Aim: Quantifying the relative contribution of environmental filtering versus limiting similarity in shaping communities is challenging because these processes often act simultaneously and their effect is scale‐dependent. Focusing on caves, island‐like natural laboratories with limited environmental variability and species diversity, we tested: (i) the relative contribution of environmental filtering and limiting similarity in determining community assembly in caves; (ii) how the relative contribution of these driving forces changes along environmental gradients. Location: Europe. Time period: Present. Major taxa studied: Subterranean spiders. Methods: We used data on distribution and traits for European cave spiders (n = 475 communities). We estimated the trait space of each community using probabilistic hypervolumes, and obtained estimations of functional richness independent of the species richness of each community via null modelling. We model functional diversity change along environmental gradients using generalized dissimilarity modelling. Results: Sixty‐three percent of subterranean spider communities exhibited a prevalence of trait underdispersion. However, most communities displayed trait dispersion that did not depart significantly from random, suggesting that environmental filtering and limiting similarity were both exerting equally weak or strong, yet opposing influences. Overdispersed communities were primarily concentrated in southern latitudes, particularly in the Dinaric karst, where there is greater subterranean habitat availability. Pairwise comparisons of functional richness across caves revealed these effects to be strongly scale‐dependent, largely varying across gradients of cave development, elevation, precipitation, entrance size and annual temperature range. Conversely, geographical distance weakly affected trait composition, suggesting convergence in traits among communities that are far apart. Main conclusions: Even systems with stringent environmental conditions maintain the potential for trait differentiation, especially in areas of greater habitat availability. Yet, the relative influence of environmental filtering and limiting similarity change with scale, along clear environmental gradients. The interplay of these processes may explain the assembly of species‐poor subterranean communities displaying high functional specialization. [ABSTRACT FROM AUTHOR]

Genus Harpactea Bristowe, 1939 Type species Dysdera latreillii Blackwall, 1832, by original designation. Remarks. Harpactea hombergii is currently stated as the type species of the genus Harpactea (World Spider Catalog 2021). It is through synonymy of Aranea hombergii and Dysdera latreillii. Templeton (1835) described a new dysderid genus Harpactes for Dysdera latreillii. He was not sure whether his specimens were conspecific with Blackwall’s (1832) Dysdera latreillii, therefore he called it D. latreillii with question mark. Vigors (in Templeton 1835), the editor of the paper, emended the name to D. templetoni. Later, Bristowe (1939) noticed that the name Harpactes was already preoccupied, so he replaced it with Harpactea. In summary, the type species of the genus Harpactea is undoubtedly Dysdera latreillii, not Aranea hombergii (see also Thaler & Knoflach 2002, Řezáč et al. 2014). Diagnostic characters. Diagnostic characters of Harpactea include the body size, colour of prosoma, leg spination and the shape of male chelicerae and copulatory organs. Harpactea are usually small to medium size spiders (carapace length 1.3–2.3 mm, although members of the group rubicunda from the eastern Meditteranean are usuay larger), with a homogeneous body shape (Fig. 1), although some species have elongated body and appendages (e.g., Fig. 1C). The prosoma is brown or yellow, usually darker in the anterior part. The abdomen shows no color patterns, its cuticle is hardly pigmented, so that grey or brownish midgut is visible. The shape of the chelicerae and the arrangement of the cheliceral teeth are uniform and characteristic for the majority of species of the genus (see the fageli type below)., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on page 337, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Bristowe, W.

It can be distinguishged from any other Iberian Harpactea by cymbium with concave retrolateral side, unlike retrolateral side of cymbium being either convex or straight, in other species (only the prolateral side is concave in some species), and concave hairless dorso-apical side. It possesses the cheliceral type minoccii (see the Materials and Methods) characterised by only three cheliceral teeth. In contrast to other two representatives of this cheliceral type, H. minoccii and H. subiasi, it has slightly obtuse posterior distal tooth (in two mentioned species it is pointed) and thicker basal cheliceral segment (Fig. 2M). Vulva is similar to that of H. algarvensis, but it can be distinguished by sclerotization only present at the median rod of the anterior arc (Fig. 8E). A couple of bands of white delicate tissue run from the epigastric furrow towards the ovary and turn dorsally in the middle of the abdomen (Fig. 8E —wt, when the spider is in certain level of saturation, it can be observed by transparency, without dissecting). It co-occurs with H. algarvensis, from which it can be distinguished by smaller size (H. algarvensis 2.2 mm, H. tavirensis 1.4–2.0 mm), darker coloration and slightly annulated legs. Description. Male. Carapace red-brown, matting (Fig. 1M). Sternum brown-yellow, matting. Chelicerae red brown. Legs yellow-brown, anterior legs and pedipalps are darker. For measurements and leg spination see the Table 1. Relative leg length: IV>I>II>III. Cymbium slightly elongated (Fig. 3M), distally widened, with concave retrolateral side. Tegulum wider than long (Fig. 5E). Conductor relatively short, slightly S-shaped. Embolus dark, extremely long, its base directs to the opposite side than the conductor but then it is bent in 180° angle, so its tip directs to the same side as conductor. Opisthosoma cylindrical, whitish. Female. All somatic characters as described for the male. The vulva is of the type algarvensis (Fig. 8E). The vulva is very small and weakly sclerotised, anterior arc, transversal bar and median rod are only tiny rudiments. Rudiment of posterior diverticle is tiny circular spot. Behind the epigastric furrow there is a paired mass of whitish tissue. Variability. Male carapace length 1.51–2.00 mm (1.77±0.14, N=9), female carapace length 1.38–2.00 mm (1.65±0.13, N=22). The twisting of embolus is variable. Moreover, its appearance depends on the angle of view. Ecology. The adults occur in early spring in leaf litter of Quercus suber and Erica forests on eastern slopes. Females lay 16– 21 eggs (N=2). Distribution.

Crop Research Institute, Prague. Etymology. Named after the Czech arachnologist Jan Dolanský, our friend who helped us to discover this species. Diagnosis. This species is characterised by long thin S-shaped conductor and embolus (Fig. 5D). Its bulbus is similar to that of H. tavirensis, but tegulum is longer than wide, and embolus is more detached from tegulum. It possesses the cheliceral type algarvensis (Fig. 2L). In contrast to the other two representatives of this cheliceral type, H. algarvensis and H. krejcii sp. nov., its posterior basal cheliceral tooth is shifted more basally (it is not next to the anterior basal tooth, Fig. 2L). The male pedipalpal tarsus is only slightly elongated, it exhibits, like in H. algarvensis, no special modifications (Fig. 3L). Description. Male (holotype). Carapace olive brown, matting (Fig. 1L). Sternum yellow-brown, matting. Chelicerae brown. Legs yellow-brown, anterior legs and pedipalps darker. For measurements and leg spination see the Table 1. Relative leg length: IV>I>II>III. Cymbium with elongated distal part (Fig. 3L), and concave basal half of the prolateral side. Tegulum large, longer than wide (Fig. 5D). Conductor thin, relatively long, S-shaped. Embolus dark, very long, thin, S-shaped, directing distally. Opisthosoma cylindrical, whitish. Female unknown. Variability. Male carapace length 1.9–2.5 mm (2.2±0.2, N=4). Ecology. It was found in relatively dry leaf litter under Eucalyptus trees on a northern slope in early spring. Distribution.

Males can be distinguished from the similar H. subiasi by very concave prolateral side of pedipalp tarsus, and by proportions of conductor and embolus. The embolus is thicker and relatively shorter, and the conductor is of similar width in its whole length, while in H. subiasi it is markedly tapering (Fig. 4E). The numbers in brackets indicate the number of spines on left legs. Measurements are in mm. ......continued on the next page ......continued on the next page The vulva is of the type minoccii. It resembles H. subiasi but it can be distinguished from the later species by larger paired posterior diverticles, easy to overlook in H. subiasi (Fig. 7B —pd) and by more compact hooks of the anchor-shaped anterior arc (Fig. 7A ven.). Description. The female has not been known so far. The somatic characters correspond with those described for the holotype male. The vulva is well developed. The anterior arc is high in ventral view. The median rod carries large crest, it does not contain any spermatheca. The anterior arc with median rod strongly resemble anchor in the ventral/dorsal view. The transversal bar carries a couple of translucent membranous pockets (Fig. 7A). Ecology. In humid leaf litter under trees or bush on shaded slopes. Females lay eggs at the beginning of spring. The presence of independent juveniles at the same time suggests a two-year life cycle. Distribution. Relatively large area comprising southern Spain (Ferrandez 1990: 37, fig. 3; Ferrandez & Ferrandez 1990: 49, fig. 4; Machado & Ferrandez 1991: 58, fig. 8) and southern Portugal., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on pages 349-354, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Ferrandez, M.

They differ by relatively longer, markedly flattened embolus. The vulva is of the type algarvensis. In contrast to the vulva of H. minoccii and H. subiasi it is reduced, without paired posterior spermathecae, small and only slightly sclerotised (Fig. 8D). In contrast to vulvae of H. tavirensis and H. crespoi sp. nov. the anterior arc is sclerotised (slightly though), it constitutes two pockets on sides of the median rod (Fig. 8D fro.). Description. The female has not been known so far. The somatic characters are as in males. The vulva is relatively small, only slightly sclerotised. Posterior diverticle is absent. Anterior arc is of rectangular shape in dorsal view, the sclerotised median rod is short.Anteriorly there are two lobes of whitish tissue connected to the anterior arc. Ecology. It was found in humid leaf litter in shaded Quercus forests or Pinus monocultures. Females were found with eggs (Range = 12–68, mean = 27, SD = 15, N = 20) in April. The presence of independent juveniles in early spring suggests a two-year life cycle. Distribution. It occurs in southern Portugal (Ferrandez 1990: 37, fig. 3; Machado & Ferrandez 1991: 58, fig. 8)., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on pages 342-343, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Le Peru, B.

Harpactea hombergii (Scopoli, 1763) (Fig. 9) Dysdera latreillii Blackwall, 1832: 190 (the first description of this species, based on ♁). Remarks. The name Harpactea hombergi has been erroneously used for this species (Řezáč et al. 2008a). Walckenaer (1830) first used the name D. hombergii for the Harpactea species. His wrong concept was adopted by the latter authors (see the above list of misidentifications). The species so far called Harpactea hombergii was first described as Dysdera Latreillii by Blackwall (1832). However, resurrecting a name that has not been used as valid for over 150 years would severely threaten nomenclatoric stability. Therefore, we propose to keep using the name hombergii for this species. Harpactea hombergii is usually incorrectly written with a single “i” (for example, World Spider Catalog 2021). It was named after Homberg, latinized in Hombergius; the genitive of Hombergi-us is then Hombergi-i. Therefore, the name “hombergii” does not fit into the cases of incorrect names that must be changed. Thus, the original spelling of the specific name should be maintained according to ICZN, articles 31–33. Material. Type material was not examined. New material. Alcos de Valdevez, Mezio, 41.886, -8.312, inside house, 2 ♁♁, 14 June 2005, leg. S. Henriques, coll. Crop Research Institute, Prague. Diagnosis. Harpactea hombergii can be easily distinguished from other Portuguese Harpactea by dark brown carapace, especially in males elongated body, slightly annulated legs, remarkably shortened tarsus of male pedipalps, and by the shape of copulatory organs. Ecology. During the day this nocturnal species can be found in leaf litter, under stones and branches lying on the ground or under bark of trees. In the Iberian Peninsula it lives in humid forests, adults are usually found in May. In central Europe it usually lives in sparse dry forests on rocks, especially with predominating Quercus spp., less often Fagus sylvatica or Pinus spp.; it matures at the end of summer. Distribution. Harpactea species with the largest area of distribution comprising most of the western, central and southern Europe. It is absent in its southernmost (southern parts of Iberian, Appenine and Balkan peninsulas), northern (Scandinavia, Baltic countries, Russia) and eastern parts (Bielorussia, Ukraine). In Spain (Ferrandez & Ferrandez 1990: 49, fig. 4) and Portugal (Fig. 9) it lives only in the northern parts, with very few southern records that probably are misidentified (see Branco et al. 2019b)., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on page 347, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Scopoli, I.

Crop Research Institute, Prague. Etymology. Named after the Czechoslovak arachnologist Stano Pekár, our friend who helped us to collect material for this study. Diagnosis. The smallest and more gracile Portuguese Harpactea species. It resembles H. gaditana, H. fageli and H. henriquesi sp. nov. by slightly elongated unmodified cymbium (Fig. 3D). It can be distinguished from the former species by spherical tegulum, no conductor and long regularly curved embolus, transversal in respect to tegulum (Fig. 4D). The reduced (small, only slightly sclerotised and without spermathecae) vulva resembles H. algarvensis, H. tavirensis and H. crespoi sp. nov. but it can be distinguished from these species by narrow posterior transversal bar bearing two furrows (Fig. 6C). It co-occurs with H. minoccii, from which it differs by smaller and lighter body. Description. Male (holotype). Carapace yellow-orange, head region darker, matting (Fig. 1D). Sternum yellow, matting. Chelicerae brown. Legs yellow, femora I and pedipalps darker. For measurements and leg spination see the Table 1. Relative leg length: IV>I>II>III. Cymbium with only slightly elongated distal part (Fig. 3D). Tegulum large, longer than wide (Fig. 4D). Conductor atrophied. Embolus dark, long, regularly bent, directing to the side. Opisthosoma cylindrical, whitish. Female. All somatic characters as described for the male. The vulva is of the type pekari (see the Material and Methods). It is very reduced and does not possess any posterior diverticle (Fig. 6C). Variability. Male carapace length 1.33–1.84 mm (1.58±0.14, N=21), female carapace length 1.51–1.60 mm (1.54±0.04, N=4). Ecology. Adults are found in early spring in leaf litter and under stones on humid northern slopes with Quercus ilex and Juniperus turbinata bush. Distribution.

Řezáč, coll. Crop Research Institute, Prague. Etymology. Named after the Portuguese arachnologist Sergio Henriques, our friend who helped us to collect material for this study. Diagnosis. Harpactea henriquesi differs from the majority of Portuguese Harpactea species by the shape of copulatory organs, in particular by slender tegulum and thin embolus and conductor of approximately the same length (Fig. 4C). Males are also characteristic by markedly slender and elongated abdomen and elongated prosoma (Fig. 1C). It resembles H. gaditana and H. fageli in that the first leg is longer than the fourth. Concerning bulbus shape, it is most similar to H. gaditana, from which it differs by base of embolus covered by the base of conductor (in H. gaditana it is not covered). Embolus is uniformly curved (Fig. 4C, in H. gaditana the distal part of embolus is less curved than the basal one). Concerning size and body proportions H. henriquesi sp. nov. is more similar to H. sciakyi Pesarini, 1988 from Spain, from which it differs by uniformly curved embolus (in H. sciakyi it is strongly bent in the middle), straight conductor with only slightly dilated apex (in H. sciakyi conductor is bent at base, its apex is strongly and suddenly spatulated), and femora I with a single, relatively weak subapical prolateral spine (in H. sciakyi femora I with a pair of strong prolateral spines). The vulva is similar to that of H. fageli, but it is relatively smaller and less sclerotised, the anterior part is terminated by a globule, it does not carry any crest for attaching muscles. Also the members of Harpactea hombergii group possess similar vulva morphology. In the only representative of this group in Portugal, Harpactea hombergii, the lateral parts of the anterior arc are bent like in anchor (Fig. 6B). Description. Male (holotype). Carapace olive brown, matting, in comparison with other Harpactea species elongated (Fig. 1C). Sternum ferruginous, matting. Chelicerae brown. Legs brown-yellow, anterior legs and pedipalps darker. Measurements and spination are shown in Table 1. Relative leg length: I>IV>II>III. Cymbium with only slightly elongated distal part (Fig. 3C, like in H. gaditana). Tegulum thin, much longer than wide (Fig. 4C). Conductor straight, directing distally. Embolus dark, parallel to conductor, but regularly bent, of the same length as conductor, directing distally. Opisthosoma cylindrical, markedly elongated and slender (Fig. 1C). Female. In females the carapace is less elongated (especially the posterior part) than in males: the ratio length / maximum width of carapace in females is 1.36–1.40, in males 1.44–1.50. Opisthosoma less elongated than in males. The vulva is of the type fageli (see the chapter Diagnostic characters) (Fig. 6B). Variability. Male carapace length 1.17–2.07 mm (1.56±0.23 (mean± SD), N=39), female carapace length 1.18– 1.79 mm (1.50±0.16, N=32). Ecology. Found in leaf litter in sparse Quercus forests. Distribution. The species was found in several sites in central-western Portugal., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on pages 346-347, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Pesarini, C.

Harpactea proxima Ferrández, 1990 (Fig. 9) H. proxima Ferrández 1990: 33, fig. 1c–d (description based on ♁); Le Peru 2011: 277, fig. 436 (♁, redrawn from Ferrández 1990). Material. Type material was not examined. Diagnosis. Harpactea proxima is very similar to H. minoccii. According to Ferrández (1990) H. minoccii differs from H. proxima by absence of femoral spines. However, all our H. minoccii specimens possess femoral spines. Their absence is very unusual in the genus Harpactea in general, which lead us to conclude that the holotype of H. minoccii is just an individual with aberrant spination. Further, H. proxima possesses conductor (not embolus as stated in Ferrández (1990)) that is uniformly curved (in H. minoccii it is sinuous— Fig. 4E). Because we found only Harpactea with bulbus morphology of H. minoccii in the region from where H. proxima was described, we can not exclude the possibility that these two morphotypes are in fact the same species. Ecology. So far unknown (cf. Ferrández 1990). Distribution. It is recorded from southern Portugal (Ferrandez 1990: 37, fig. 3; Machado & Ferrandez 1991: 58, fig. 8)., Published as part of Řezáč, Milan, Cardoso, Pedro & Řezáčová, Veronika, 2023, Review of Harpactea ground-dwelling spiders (Araneae: Dysderidae) of Portugal, pp. 335-364 in Zootaxa 5263 (3) on page 355, DOI: 10.11646/zootaxa.5263.3.2, http://zenodo.org/record/7804268, {"references":["Le Peru, B.

Cave-obligate organisms usually have smaller ranges and their assemblages have higher beta diversity than their epigean counterparts. Phylogenetic and functional diversity is usually low in cave communities, leading to taxonomic and functional disharmony, with entire groups missing from the subterranean realm. The objective of this work is to compare range, beta diversity, phylogenetic and functional diversity, taxonomic and functional disharmony of epigean versus troglobiont spiders in the Iberian Peninsula. The median extent of occurrence was found to be 33 times higher for epigean than for cave species. Beta diversity was significantly higher for troglobiont assemblages. Cave assemblages present lower phylogenetic and functional diversities than expected by chance. Taxonomic disharmony was noticeable, with many speciose families, namely Gnaphosidae, Salticidae and Lycosidae, absent in caves. Functional disharmony was equally high, with ambush hunters and sensing web weavers being absent in caves. The small range and high beta diversity of troglobiont spiders in the Iberian Peninsula is typical of many cave-obligate organisms, caused by the fragmentation and isolation of cave systems and the low vagility and high habitat specialization of species. Caves were colonized mainly by pre-adapted lineages, with high proportions of eutroglophile species. Some families no longer occur in surface habitats, possibly since the last glaciations, and currently are restricted to caves in the region. Few hunting strategies and web types are efficient in caves and these dominate among the troglobiont species. As troglobiont communities are of low alpha diversity, with low functional redundancy, have narrow ranges, present high levels of population fragmentation and are taxonomically unique, they should present higher proportions of imperilled species than epigean spiders in the Iberian Peninsula. Some species are probably endangered and require urgent conservation measures.

Aim: Much research has focused on the separate and combined effects of habitat and geography on species communities, both in mainland and island ecosystems. However, few studies have looked into the differences among communities inhabiting different island habitats. Here we aim to determine the contributions of habitat filtering and dispersal to the differences in taxonomic structure of island communities across geographic scales. Location: Sixty plots in two habitats (forest and dry habitat) across eight islands of the Macaronesian archipelagos of the Azores, Madeira, Canary Islands and Cabo Verde. Taxon: Spiders (Araneae). Methods: We generated community data by using the optimised and standardised COBRA sampling protocols. We tested the differences in three beta diversity metrics ( βTotal, βReplacement and βRichness) for each habitat and dispersal category separately, across geographic scales through nested non-parametric PerMANOVA. We tested if dispersal and habitat influenced differences between the communities of the same area by applying a PERMDISP to βreplacement, and using the distances in linear mixed models. We tested the effects of habitat and dispersal on species relative abundances (SADs) and rarity by building Gambin models for each community and dispersal group separately. Results: Communities grouped according to archipelago and habitat, in terms of taxonomic similarity. In general, β diversity increased with geographic scale, and was greater in dry habitats. βReplacement among communities of the same region was greater in dry habitats than in forests, and this difference was stronger for rare ballooners. Dry habitat communities showed more species with low abundances (rare species) at different spatial scales. Main conclusions: Our findings reveal that habitat type does not only condition the processes behind community assembly but also the scale at which they occur. Indeed, our findings are highly relevant for theories on across and within island community assembly as well as for biodiversity conservation., Field work was supported by two projects: 1) the ERA-Net Net-Biome research framework, Canary Islands Government ACIISI grants SE-12/02 (PO), SE-12/03 (JCC), SE-12/04 (BE), co-financed by FEDER, Portuguese FCT-NETBIOME grant 0003/2011 (PB); and 2) FCT MACDIV – FCT PTDC/BIABIC/0054/2014.

Despite their ecological importance and diversity, spiders (Arachnida: Araneae) are underrepresented in conservation policies in comparison to other groups. We review all extant conservation tools focusing on spiders in Europe, highlighting general patterns, limitations, gaps, and future directions. We assembled a comprehensive online database reporting all available information concerning the legal protection and conservation status of 4,154 spider species. Existing international legislation has limited coverage, with only one species listed in the Bern Convention and EU Habitats Directive. At the national and subnational levels, 178 species are formally mentioned in the legislation of 19 European countries. Moreover, the International Union for Conservation of Nature (IUCN) includes assessments for 301 species worldwide, 164 of these threatened and eight native to Europe. In addition, spiders are mentioned in Regional Red Lists and Red Books in 28 out of 42 European countries considered in this review. Northern and Central European countries have the highest percentage of species assessed at the regional level in Red Lists and Red Books. The Mediterranean basin has the highest spider diversities in Europe but conservation efforts are lacking, both in terms of assessments and national or subnational legislation. Among European species, Dolomedes plantarius, Argyroneta aquatica and Eresus kollari are the most frequently mentioned in European conservation measures, possibly due to their ecological traits and their strict association with declining habitats. Considering the current threats to spiders in Europe, the protection of large areas of suitable habitat should be considered as the most effective approach to spider conservation.

Background: Long-term studies are key to understand the drivers of biodiversity erosion, such as landuse change and habitat degradation, climate change, invasive species or pollution. The long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) started in 2012 and focuses on arthropod monitoring, using SLAM (Sea, Land and Air Malaise) traps, aiming to understand the impact of the drivers of biodiversity erosion on Azorean native forests (Azores, Portugal). This is the fourth contribution including SLAM project data and the second focused on the spider fauna (Arachnida, Araneae) of native forests on two islands (Pico and Terceira). In this contribution, we describe data collected between 2019 and 2021 and we analyse them together with a previously published database that covered the 2012-2019 period, in order to describe changes in species abundance patterns over the last ten years. New information: We present abundance data of Azorean spider species for the 2019-2021 period in two Azorean Islands (Terceira and Pico). We also present analyses of species distribution and abundance of the whole sampling period. In the period of 2019-2021, we collected a total of 5110 spider specimens, of which 2449 (48%) were adults. Most juveniles, with the exception of some exotic Erigoninae, were also included in the data presented in this paper, since the low diversity of spiders in the Azores allows a relatively precise specieslevel identification of this life-stage. We recorded a total of 45 species, belonging to 39 genera and 16 families. The ten most abundant species were composed mostly of endemic or native non-endemic species and only two exotic species (Tenuiphantes tenuis (Blackwall, 1852) and Dysdera crocata C. L. Koch, 1838). They included 4308 individuals (84%) of all sampled specimens and were the dominant species in Azorean native forests. The family Linyphiidae was the richest and most abundant taxon, with 15 (33%) species and 2630 (51%) specimens. We report Cheiracanthium mildei L. Koch, 1864, a non-native species, from Pico Island for the first time. We found no new species records on Terceira Island. This publication contributes to increasing the baseline information for future longterm comparisons of the spiders on the studied sites and the knowledge of the arachnofauna of the native forests of Terceira and Pico, in terms of species abundance, distribution and diversity across seasons for a 10 years period.

Background A large scale semi-quantitative biodiversity assessment was conducted in white oak woodlands in areas included in the Spanish Network of National Parks, as part of a project aimed at revealing biogeographic patterns and identify biodiversity drivers. The semi-quantitative COBRA sampling protocol was conducted in sixteen 1-ha plots across six national parks using a nested design. All adult specimens were identified to species level based on morphology. Uncertain delimitations and identifications due to either limited information of diagnostic characters or conflicting taxonomy were further investigated using DNA barcode information. New information We identified 376 species belonging to 190 genera in 39 families, from the 8,521 adults found amongst the 20,539 collected specimens. Faunistic results include the discovery of 7 new species to the Iberian Peninsula, 3 new species to Spain and 11 putative new species to science. As largely expected by environmental features, the southern parks showed a higher proportion of Iberian and Mediterranean species than the northern parks, where the Palearctic elements were largely dominant. The analysis of approximately 3,200 DNA barcodes generated in the present study, corroborated and provided finer resolution to the morphologically based delimitation and identification of specimens in some taxonomically challenging families. Specifically, molecular data confirmed putative new species with diagnosable morphology, identified overlooked lineages that may constitute new species, confirmed assignment of specimens of unknown sexes to species and identified cases of misidentifications and phenotypic polymorphisms.

Aim: Habitat diversity has been linked to the diversity and structure of island communities, however, little is known about patterns and processes within habitats. Here we aim to determine the contributions of habitat type and inferred dispersal frequency to the differences in taxonomic structure between assemblages in the same island habitat. Location: The Macaronesian archipelagos (Azores, Madeira, the Canary Islands and Cabo Verde). Taxon: Spiders (Araneae). Methods: We established forest and dry habitat sites (each with five plots) on two islands per archipelago. We collected spiders using standardised sampling protocols. We tested the differences in beta diversity separately for each habitat and for each inferred category of ballooning (an aerial dispersal strategy) frequency across geographic scales through nested non-parametric permutational multivariate analyses of variance. We then tested whether ballooning and habitat influenced heterogeneity in species composition (dispersion in beta diversity) in the two habitat types. We analysed the effects of habitat and ballooning on species abundance distribution (SAD) and rarity by fitting Gambin models and evaluating the contribution of ballooning categories to SAD. Results: Communities of the same archipelago and habitat were taxonomically more similar, and beta diversity increased with geographic scale, being greater in dry habitats. There was greater species replacement among assemblages in dry habitats than in forests, with greater differences for rare ballooners. There were no differences in SAD between habitats although dry habitat sites seemed to harbour more species with low abundances (rare species) than forests. Main conclusions: Habitat type does not only condition the differences between spider assemblages of the same habitat but also the scale at which they occur. These differences may be determined by the heterogeneity in the physical structure of each habitat as well as how much this structure facilitates aerial dispersal (ballooning), and should be considered in theories/hypotheses on island community assembly as well as in conservation strategies.

Online open databases are increasing in number, usefulness, and ease of use. There are currently two main global databases for spiders, the World Spider Catalogue (WSC) and the World Spider Trait (WST) database. Both are regularly used by thousands of researchers. Computational tools that allow effective processing of large data are now part of the workflow of any researcher and R is becoming a de facto standard for data manipulation, analysis, and presentation. Here we present an R package, arakno, that allows interface with the two databases. Implemented tools include checking species names against nomenclature of the WSC, obtaining and mapping data on distribution of species from both the WST and the Global Biodiversity Information Facility (GBIF), and downloading trait data from the WST. A set of tools are also provided to prepare data for further statistical analysis. [ABSTRACT FROM AUTHOR]

session 01 - Diversity and faunistics; World experts of different disciplines, from molecular biology to macroecology, recognize the value of cave ecosystems as ideal ecological and evolutionary laboratories. Among other subterranean taxa, spiders stand out as intriguing model organisms for their ecological role of top-predators, their unique adaptations to the hypogean medium and their sensitivity to anthropogenic disturbance. Here, we provide a general overview of the spider families recorded in hypogean habitats in Europe–20 families including nearly 500 species, most of them with restricted distributions. We also review the different adaptations of hypogean spiders to subterranean life and summarize the information gathered so far about their origin, population structure, ecology and conservation status. Taxonomic knowledge on subterranean spiders in Europe appears to be well, but not exhaustively documented. The origin of the European assemblages is mostly explained by past climate dynamics, although other factors are likely to be involved. Most of the macroecological issues related to spiders in European caves are based on qualitative assessments or have been quantified only at a sub-regional scale. In order to shed light on cave spiders’ biogeography and the macroecological patterns driving the diversity of European subterranean spiders we created the CAWEB network, a spontaneous collaboration between subterranean arachnologists from 30 different European countries. We here present the team and provide some preliminary results, which highlight Southern Europe as an important hot-spot for the European subterranean spider diversity.

session 01 - Diversity and faunistics; World experts of different disciplines, from molecular biology to macroecology, recognize the value of cave ecosystems as ideal ecological and evolutionary laboratories. Among other subterranean taxa, spiders stand out as intriguing model organisms for their ecological role of top-predators, their unique adaptations to the hypogean medium and their sensitivity to anthropogenic disturbance. Here, we provide a general overview of the spider families recorded in hypogean habitats in Europe–20 families including nearly 500 species, most of them with restricted distributions. We also review the different adaptations of hypogean spiders to subterranean life and summarize the information gathered so far about their origin, population structure, ecology and conservation status. Taxonomic knowledge on subterranean spiders in Europe appears to be well, but not exhaustively documented. The origin of the European assemblages is mostly explained by past climate dynamics, although other factors are likely to be involved. Most of the macroecological issues related to spiders in European caves are based on qualitative assessments or have been quantified only at a sub-regional scale. In order to shed light on cave spiders’ biogeography and the macroecological patterns driving the diversity of European subterranean spiders we created the CAWEB network, a spontaneous collaboration between subterranean arachnologists from 30 different European countries. We here present the team and provide some preliminary results, which highlight Southern Europe as an important hot-spot for the European subterranean spider diversity.

Background: There is an increasing demand for databases including species trait information for biodiversity and community ecology studies. The existence of trait databases is useful for comparative studies within taxa or geographical regions, but there is low availability of databases for certain organisms. Here we present an open access functional trait database for spiders from Macaronesia and the Iberian Peninsula, recording several morphological and ecological traits related to the species life histories, microhabitat and trophic preferences. New information: We present a database that includes 12 biological traits for 506 spider species present in natural forests of the Iberian Peninsula (Spain) and three Macaronesian archipelagoes (Azores, Madeira and Canary Islands). The functional trait database consists of two sections: 1. individual-level data for six morphological traits (total body size, prosoma length, prosoma width, prosoma height, tibia I length and fang length), based on direct measurements of 2844 specimens of all spider species; and 2. species-level aggregate data for 12 traits (same 6 morphological traits as in the previous section plus dispersal ability, vertical stratification, circadian activity, foraging strategy, trophic specialization and colonization status), based on either the average of the direct measurements or bibliographic searches. This functional trait database will serve as a data standard for currently ongoing analyses that require trait and functional diversity statistics. [ABSTRACT FROM AUTHOR]

Background The semideciduous Atlantic Forest is one of the most diverse ecosystems in the world with a great diversity of spiders. Most spider-related studies in this ecosystem focused on species richness and composition; however, little is known about their trait diversity (including morphological, ecological and/or physiological traits). Two main datasets were compiled to generate a complete record of spider traits for this ecosystem. New information Here, we present two datasets about 259 species of spiders from the semideciduous Atlantic Forest of Argentina. The trait data set compiled information of morphological and ecological traits such as body size, femur length, ocular distance, foraging strategy, prey range, circadian activity and stratum preference; traits were assessed by species considering sexual dimorphism. The second dataset included information about phenology (season when spiders were collected), number of individuals assessed by species and presence/absence of spiders in the different sample sites. This dataset has high potential to help researchers in recording the state of a component of biodiversity (functional) and contributes with the study of ecosystem services and species conservation.

Aim: The main aims were to determine: (a) the relative contribution of species replacement and richness difference from components to overall taxonomic (TDβ) and functional (FDβ) beta diversity of spider communities; (b) the degree to which TDβ and FDβ components can be explained by the environmental or geographic predictors; (c) whether FDβ components were lower than expected given the underlying TDβ variation. Location: This study was carried out in 22 oak forest sites across the Iberian Peninsula. The area comprises two biogeographic regions, Eurosiberian (North) and Mediterranean (Centre and South). Methods: Spiders were sampled using a standardized protocol. A species x traits matrix was constructed. Total taxonomic (TDβtotal) and total functional (FDβtotal) beta diversity were calculated, by pairwise comparisons, and partitioned into their replacement (βrepl) and richness difference (βrich) components. Mantel tests were used to relate taxonomic and functional dissimilarity with environmental and geographic distances. A spatial eigenfunction model was constructed and the variation in TDβ and FDβ explained by environment and geographic predictors was quantified. Null models were used to test if FDβ was higher or lower than expected given TDβ. Results: βrepl was the dominant component contributing to 84.2% and 72.8% for TDβtotal and FDβtotal, respectively. TDβtotal and FDβtotal (and their replacement components) were higher between‐ than within‐biogeographic regions. TDβtotal and TDβrepl were positively correlated with environmental and geographic distances, even when controlling for a biogeographic effect, but their functional counterparts were only correlated with environmental distance. Variation partitioning showed that pure environmental and spatially structured environmental effects had a small contribution to beta diversity, except for TDβrich. The observed slopes of the regressions of FDβtotal and FDβrepl in relation to environmental distance were slower than the null model expectations. Main Conclusions: Spider assemblage variation was mainly determined by the replacement, and not the net loss, of species and traits. TDβ was influenced by niche filtering and dispersal limitation, whereas FDβ was mainly generated by niche filtering. A high level of functional convergence among spider communities, despite the high taxonomic divergence, revealed the signal of replacement of species performing similar functions across sites.

Background: Here we present the data obtained from the samples collected as part of a large research project (MACDIV) which aims at understanding the drivers of spider (Araneae) community assembly in Macaronesian islands. To obtain the data, we applied the sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment), in twelve 50 m x 50 m native forest plots and five dry habitat plots on the island of Madeiraand in 5 dry habitat plots on the island of Porto Santo. Through this publication, we contribute to the knowledge of the arachnofauna of the Madeiran archipelago. New information: From the samples that we collected, we obtained a total of 14,902 specimens, of which 49% were adults (7,263). We identified these specimens to 87 species and 18 morphospecies (undescribed), belonging to 26 families. Species of the family Linyphiidae dominated the samples, with 24 (morpho)species. Out of the 105 recorded (morpho)species, 34 were endemic, 26 native non-endemic, 22 introduced and 23 species of unknown origin. We report seven new records of possibly recently introduced species in the Madeiran archipelago. We also present 21 new records for Madeira island and 32 for Porto Santo (33 for the whole archipelago). [ABSTRACT FROM AUTHOR]

Turinyphia cavernicola Wunderlich, 2008 is one of the two endemic cavernicolous spiders known from the Azorean archipelago (Portugal). In spite of relatively intensive searches, this species is known from only three caves, but with a single sustainable subpopulation restricted to the Algar do Carvão show cave. With an observed extent of occurrence (EOO) of 2 km² and an area of occupancy (AOO) around 0,75 km², it presents a restricted range, severe fragmentation, and continuing decline in EOO, AOO, habitat quality, number of locations and subpopulations caused by the ongoing threat from pasture intensification and tourist activities in the cave systems.

Trabajo presentado en el II International Conference on Island Evolution, Ecology and Conservation, celebrado en Angra do Heroísmo, Islas Azores (Portugal) del 18 al 22 de julio de 2016., Current island native forest habitats are particularly important repositories of threatened endemic arthropods that are frequently restricted to higher elevations. As a consequence of the ongoing deleterious impacts of invasive species, land-use changes and climatic changes, the long-term conservation of island forest mountain invertebrates is considered a priority. During the project NETBIOME –ISLANDBIODIV a modified version of COBRA protocol was used to inventory alpha diversity of spiders and beetles on pristine native forest of three islands, Terceira (Azores), Tenerife (Canaries) and La Réunion (Mascarenes). The modified COBRA protocol incorporated the following standardized methods that totaled 28 samples: AAS - active aerial searching during the night (4 hours); BLM - searching under bark, lichens and mosses during the day (2 hours); TWS - searching in decaying trunks, dead wood on the ground, and under stones during the day (2 hours); FBD - foliage beating during the day (2 hours); FBN - foliage beating during the night (2 hours); FSD - foliage sweeping during the day (2 hours); FSN - Foliage sweeping during the night (2 hours); PIT- Pitfall traps (12 samples). Monitoring is essentially different from inventorying, that was the main objective of the original COBRA protocol. Here we will describe a new optimized and standardized COBRA protocol designed to respond to long-term changes of spider and beetle diversity, i.e., designed to measure beta diversity. Using data collected in the above mentioned islands and using simulation methods the new COBRA protocol was optimized to only six samples using: AAS - active aerial searching during the night (four hours); FBN - foliage beating during the night (two hours). With this new solution it is possible to quantify and monitor long-term changes in communities with minimal effort and using a method that proved to be suitable, efficient, feasible, flexible, transparent and accountable.

Additional material examined. Paratype ♀ of Lepthyphantes acoreensis Wunderlich, 1992 (misidentification), Flores, Lago do Seco (this should probably refer to Lagoa Seca, as there is no lagoon in Flores with that name), SNM 60150 ��� 124, epigynum missing. Etymology. The species name refers to the local dominant endemic tree, Juniperus brevifolia combined with the Latin verb colo (to live in). Diagnosis. Males of Canariphantes junipericola n. sp. can be diagnosed from all other congeners by the combination of the following palp characters: absence of Fickert���s gland, massive lamella characteristica, and paracymbium bearing a keel, resultant from the merged apical and anterior pockets (Fig. 9). Females are diagnosed by the protruding lateral lobes of scape (Fig. 13) and coiled entrance grooves (Figs. 14, 15). Description. Male holotype (from Flores). Total length 2.7. Prosoma 1.3 long, 1.1 wide. All eyes except AME equal in size, large, AME small, posterior row slightly recurved, anterior row recurved. PME separated by less than half their diameter, separated from PLE by half their diameter. PLE touching ALE. ALE separated from AME by half the diameter of the former. AME separated by half their diameter. AME separated from PME by the diameter of the latter. Clypeus height ca. 2.5 times an AME diameter. Chelicerae with 40 to 50 stridulatory striae, 3 promarginal teeth and 6 retromarginal denticles. Prosoma yellow. Sternum anteriorly truncated, roughly triangular, darkened. Opisthosoma whitish with a black longitudinal band in the cardiac area and with posterior black chevrons (Fig. 25), ventrally black. Legs with a prolateral spine in femur I; all patellae with 1 dorsal spine; 2 dorsal, 1 prolateral and 1 retrolateral spine in tibia I, 2 dorsal and 1 retrolateral spine in tibia II and 2 dorsal spines in tibiae III and IV; 1 dorsal, 1 prolateral and 1 retrolateral spine in all metatarsi. TmI 0.2. TmIV absent. L Sp Ti I 2.7, L Sp Ti IV 3.8. Overall color yellow, with black annulations in femora and tibiae near the joints. Palp (Figs. 9���12). Patella with 1 dorsal spine, roughly as long as diameter of patella. Tibia as long as wide, with 1 dorsal spine, twice the diameter of tibia. Tibial spine roughly twice the length of patellar spine. Cymbium with a retrolateral keel. Paracymbium simple, with a distal keel, resultant from the merged anterior and apical pockets, with 4 to 6 hairs in its basal part. Suprategular apophysis a wide tooth, with a sclerotized dorsal arch above the large opening of the column. Lamella characteristica wide, terminally pointed. Terminal apophysis with a small ventral branch and a large dorsal branch, terminally pointed. Radix base widely rounded, without a pointed tail. Median membrane laminar. Embolus with a lobed thumb extending retrolaterally, anteriorly and dorsally. Fickert���s gland absent. Female (from Flores). Total length 4.0. Prosoma 1.8 long, 1.4 wide. Eyes same as in males except the distance of PME, separated by half their diameter. Clypeus height ca. 3.5 times an AME diameter. Chelicerae with 30 to 40 stridulatory striae, 3 promarginal teeth and 7 retromarginal denticles. Prosoma yellowish to brown. Sternum as in male. Opisthosoma with a dorsal reticulate pattern of black patches interspersed with whitish areas, ventrally black (Fig. 26). Leg spination same as in male. TmI 0.2. TmIV absent. Overall color yellowish to brown, with black annulations in femora and tibiae near the joints. Epigynum (13���15). Scape sigmoid, with short proximal part, as long as wide, somewhat angular, with a total reduction or merging of the median part of the scape, distal part ending into rounded sclerotized lateral lobes on each side. Stretcher wide, with a large pit. Posterior median plate protruding in ventral view, heart-shaped in dorsal view. Entrance grooves coiled, ascending from the distal part of scape to the proximal part of scape into a coil, then proceeding in posterior direction to the oval receptacula. Variation. Total body size in male varies from 2.6 to 2.8, in female from 3.5 to 4.0. Prosoma length from 1.1 to 1.2 in male, from 1.3 to 1.6 in female. Prosoma width in male varies from 0.9 to 1.0, in female from 1.1 to 1.4. Distribution. Endemic to the island of Flores (Fig. 8). Natural history. This species is yet to be collected by direct hand sampling, having appeared solely through the use of pitfall trapping. Although several sites in Flores Island were sampled covering a wide area in the two main native forest areas and other habitat types spread through the island, the site where this species occurs is a small native forest fragment and the only one sampled in this island devoid of abundant Sphagnum mosses covering the ground. In this small patch of Juniperus brevifolia dominated forest, the ground has few or little herbaceous cover, due to a closed canopy. We can safely assume that C. junipericola builds its webs on the ground layer of the shady J. brevifolia forest. In other sites with J. brevifolia cover but no extensive shade or with abundant moss cover, C. junipericola is yet to be found. Adults were collected solely in June and July., Published as part of Crespo, Lu��s Carlos, Bosmans, Robert, Cardoso, Pedro & Borges, Paulo A.

Entrance grooves coiled, ascending from distal part of scape along the median part into proximal part coiling anteriorly and then posteriorly into the oval receptacula. Distribution. Endemic to the island of Santa Maria (Fig. 8). Natural history. This species builds typical sheet-webs at ground level. The site where the majority of these spiders were caught is a marginal forest patch on Pico Alto Nature Reserve, and it was mainly composed of the exotic Cryptomeria japonica and the invasive species Acacia sp. and Pittosporum undulatum, with a residual presence of native trees. Adults were collected from June to August, but the absence of sampling outside this period might obscure the complete phenology of this species.

All specimens collected by pitfall trapping and deposited at EDTP. Diagnosis. Males of Canariphantes acoreensis can be diagnosed from all other congeners by the combination of the following palpal characters: absence of Fickert���s gland, paracymbium with a bifurcated tip (Fig. 1) and terminal apophysis with several apical digitiform processes (Figs. 3���4). Females are more difficult to diagnose because the epigynum is very similar to that of C. zonatus (see Bosmans 2006), but it can be distinguished from it (and all other congeners) by the short and rounded proximal part of scape (Figs. 5���7). Description. Male (from Terceira). Total length 2.4. Prosoma 1.0 long, 0.8 wide. All eyes except AME equal in size, large, AME small, posterior row slightly recurved, anterior row recurved. PME separated by half their diameter, separated from PLE by less than half their diameter. PLE touching ALE. ALE separated from AME by half the diameter of the former. AME separated by less than half their diameter. AME separated from PME by the diameter of the latter. Clypeus height ca. two AME diameters. Chelicerae with roughly 20 stridulatory striae, 3 promarginal teeth and 4 retromarginal denticles. Prosoma yellow. Sternum anteriorly truncated, roughly triangular, black. Opisthosoma whitish with a dorsal pattern of black chevrons (Fig. 23). Legs with a prolateral spine in femur I; all patellae with 1 dorsal spine; tibiae I and IV with 2 dorsal, 1 prolateral and 1 retrolateral spine, tibiae II and III with 2 dorsal and 1 prolateral spine. Metatarsi with 1 dorsal spine. TmI 0.16. TmIV absent. L Sp Ti I 5, L Sp Ti IV 5.8. Legs uniformly dark yellow. Palp (Figs. 1���4). Patella with 1 dorsal spine, 3 times longer than diameter of patella. Tibia slightly longer than wide, with 1 dorsal spine, as long as diameter of tibia. Tibial spine roughly half the length of patellar spine. Three tibial trichobotria present, 2 retrolateral, 1 dorsal. Cymbium with a retrolateral keel. Paracymbium simple, with an incised tip, the inner tooth larger than the outer, with 6 to 7 hairs scattered from the basal to the median section. Suprategular apophysis hookshaped in ventral view, directed anteriorly in retrolateral view, with a small sclerotized dorsal arch close to the column opening. Lamella characteristica simple, with an incised distal part. Embolic division with a terminal apophysis with several apical, small, digitiform processes. Lamella characteristica and terminal apophysis separated by a membranous area bearing two small teeth, which can be variable in size. Radix unsclerotized, with a short, pointed tailpiece. Median membrane laminar. Embolus with a lobed thumb extending retrolaterally and dorsally. Fickert���s gland absent (contra Wunderlich 1992). Female (from Terceira). Total length 2.8. Prosoma 1.3 long, 1.0 wide. Eyes same as in male. Clypeus height ca. three AME diameters. Chelicerae with roughly 20 stridulatory striae, 3 promarginal teeth and 5 retromarginal denticles. Prosoma same color as in male. Sternum as in male. Opisthosoma with a dorsal pattern of black chevrons, these are more diffuse than those of males and sometimes only interspersed white patches appear in a black opisthosoma (Fig. 24). Leg spination and coloration as in male. L Sp Ti I 3.6, L Sp Ti IV 4.7. Epigynum (Figs. 5���7). Proximal part of scape short, wide and rounded, directly passing into distal part, with a total reduction or merging of the median part of scape; distal part of scape reduced, lateral lobes and stretcher very short (Figs. 5���7). Posterior median plate not visible in ventral view, heart-shaped in dorsal view. Entrance grooves not coiled, proceeding from the distal part of scape into the proximal part of scape and almost directly into the oval receptacula. Variation. Total body size in male varies from 1.9 to 2.5, in female from 2.8 to 3.1. Prosoma length from 0.9 to 1.1 in male, from 1.2 to 1.4 in female. Prosoma width in female varies from 0.9 to 1.1. Some female specimens present 2 prolateral spines in Femur I. Comments. In the original description of C. acoreensis by Wunderlich (1992: 567, Fig. 407) illustrated an epigynum with coiled entrance grooves and a wide stretcher. This morphology was not consistent with the genital structure of recently collected females together with males of C. acoreensis from nearly all the Azorean islands of the central group (Terceira, S��o Jorge and Pico). All collected females appeared to have an epigynum differing from Wunderlich���s description, except for one single female from Flores. The first author studied the type material deposited by Wunderlich at ULT and SNM. All males and females of the central group of islands appeared to be identical to our specimens, but this could not be confirmed for a female from Flores islands with the missing epigynum. Since none of the females of the type series of C. acoreensis has an epigynum resembling Wunderlich���s figures, the female with the missing excised epigynum must be the one used by Wunderlich to describe the female of C. acoreensis. Both females from Flores belong in fact to a new species described below. Distribution. The central group of islands with native forest patches (Terceira, S��o Jorge, Pico and Faial) (Fig. 8). Although C. acoreensis was cited from Faial (Wunderlich 1992), the referred material was not found at ULT, thus rendering the presence of C. acoreensis unconfirmed. Natural history. This species builds small sheet-webs at ground level, exclusively in patches of native laurel forest. Adults were collected from May to September, but sampling outside this period was not performed., Published as part of Crespo, Lu��s Carlos, Bosmans, Robert, Cardoso, Pedro & Borges, Paulo A.

Macroecologists seek to identify drivers of community turnover (β-diversity) through broad spatial scales. However, the influence of local habitat features in driving broad-scale β-diversity patterns remains largely untested, owing to the objective challenges of associating local-scale variables to continental-framed datasets. We examined the relative contribution of local- versus broad-scale drivers of continental β-diversity patterns, using a uniquely suited dataset of cave-dwelling spider communities across Europe (35–70° latitude). Generalized dissimilarity modelling showed that geographical distance, mean annual temperature and size of the karst area in which caves occurred drove most of β-diversity, with differential contributions of each factor according to the level of subterranean specialization. Highly specialized communities were mostly influenced by geographical distance, while less specialized communities were mostly driven by mean annual temperature. Conversely, local-scale habitat features turned out to be meaningless predictors of community change, which emphasizes the idea of caves as the human accessible fraction of the extended network of fissures that more properly represents the elective habitat of the subterranean fauna. To the extent that the effect of local features turned to be inconspicuous, caves emerge as experimental model systems in which to study broad biological patterns without the confounding effect of local habitat features.

SPIDER ecology ,ARACHNIDA classification ,MACROECOLOGY ,ECOSYSTEM services - Abstract
Background Spiders (Arachnida: Araneae) are widespread in subterranean ecosystems worldwide and represent an important component of subterranean trophic webs. Yet, global-scale diversity patterns of subterranean spiders are still mostly unknown. In the frame of the CAWEB project, a European joint network of cave arachnologists, we collected data on cavedwelling spider communities across Europe in order to explore their continental diversity patterns. Two main datasets were compiled: one listing all subterranean spider species recorded in numerous subterranean localities across Europe and another with high resolution data about the subterranean habitat in which they were collected. From these two datasets, we further generated a third dataset with individual geo-referenced occurrence records for all these species. New information Data from 475 geo-referenced subterranean localities (caves, mines and other artificial subterranean sites, interstitial habitats) are herein made available. For each subterranean locality, information about the composition of the spider community is provided, along with local geomorphological and habitat features. Altogether, these communities account for > 300 unique taxonomic entities and 2,091 unique geo-referenced occurrence records, that are made available via the Global Biodiversity Information Facility (GBIF) (Mammola and Cardoso 2019). This dataset is unique in that it covers both a large geographic extent (from 35° south to 67° north) and contains high-resolution local data on geomorphological and habitat features. Given that this kind of high-resolution data are rarely associated with broad-scale datasets used in macroecology, this dataset has high potential for helping researchers in tackling a range of biogeographical and macroecological questions, not necessarily uniquely related to arachnology or subterranean biology.

Background The data presented here come from samples collected as part of two recent research projects (NETBIOME - ISLANDBIODIV and FCT - MACDIV) which aimed at understanding the drivers of community assembly in Macaronesian islands. We applied the sampling protocol COBRA (Conservation Oriented Biodiversity Rapid Assessment, Cardoso 2009) in sixteen 50 m x 50 m native forest plots in the Azorean Islands of Pico (6 plots) and Terceira (10 plots) to assess spider diversity. Through this publication, we contribute to the knowledge of the arachnofauna of the Azores and, more specifically, to that of the islands of Pico and Terceira. New information The collected samples yielded 8,789 specimens, of which 45% were adults (3,970) belonging to 13 families, 36 species and three morphospecies that have yet to be described. Species of the family Linyphiidae dominated the samples, with 17 species and two morphospecies that have yet to be described (48% of the taxa). Out of the identified (morpho)species, 16 were introduced, 13 Azorean endemic (three of which were undescribed) and seven native (five of them Macaronesian endemics). We report the first record of the introduced species Haplodrassus signifer and Agyneta decora in Pico Island. [ABSTRACT FROM AUTHOR]

Background The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within available resources to assess all known species. In such cases, a random sample of species might be selected for assessment and the results derived from it extrapolated for the entire group - the Sampled Red List Index (SRLI). The current contribution is the final in four papers that will constitute the baseline of a future spider SRLI encompassing 200 species distributed across the world. [ABSTRACT FROM AUTHOR]

Savigniorrhipis topographicus Crespo new species (figs. 9���16; 19���20) Type material. Holotype male, S��o Jorge: Topo Natural Reserve, (UTM 26 S 421857 4272031, datum WGS 84), VIII. 2000 (P.A.V. Borges et al. leg.), deposited at EDTP; Paratypes: from same locality and date as holotype: 1 ♂ and 2 ♀ (P.A.V. Borges et al. leg.), deposited at EDTP; 2 ♂ and 3 ♀ (P.A.V. Borges et al. leg.), deposited at SNM. Additional material. 1 ♂, same locality and date as holotype (without opisthosoma). S��o Jorge: Topo Natural Reserve (UTM 26 S 422089 4271756, datum WGS 84) 13.IX- 1.X. 2010: 2 ♂ and 1 ♀ (P.A.V. Borges et al. leg.), deposited at EDTP. Diagnosis. The males of this species differ from S. acoreensis by the shape of the anterior radical process, the posterior radical process, the coiled embolus and the tibial apophysis. Females can be diagnosed by the epigynal folds that divide the dorsal plate only slightly and converge anteriorly, and by the shape of the copulatory ducts. Etymology. The species name ��� topographicus ��� is an adjective, showing its affinity with the soil stratum (in contrast to S. acoreensis, dwelling in canopies). The species epithet, composed of two segments ��� topo ��� and ��� graphicus ���, also relates to the fact that topo is the site of the discovery, the Topo Natural Reserve, and that graphicus could also refer to the presence of an abdominal pattern. Description. Male. Total length 1.45 (1.37���1.50). Prosoma 0.67 (0.58���0.72) long, 0.52 (0.50���0.55) wide. Male cephalic area slightly elevated, without tubercles or sulci but with distinct concavity behind the eyes (fig. 14). Clypeus not protruding. Eye region of prosoma with few small hairs. Eyes in a compact group. Anterior row of eyes recurved. Posterior row procurved. AME separated from ALE by the diameter of the former. AME separated by half their diameter. PME separated from AME roughly two times the diameter of the former. PLE touching ALE. PME separated by their diameter. PME separated from PLE by 1.5 times the diameter of the former. Coloration of prosoma and legs yellowish to brown. Sternum slightly darker. Chelicerae with 10 to 15 imbricated stridulatory striae, with 5 promarginal and 4 smaller retromarginal denticles. Opisthosoma generally black with a dorsal pattern of non-pigmented patches along its dorsal side (specimens were captured with pitfall traps and the conservation of the abdominal marks might differ from living specimens). Legs with basal and apical spines on tibiae I and II, and one basal in tibiae III and IV (2211). L Sp Ti I-II = 1.4; L Sp Ti III���IV = 2.2. Patelar apical spine present on all legs. Measurements of legs in Table 3. Male palp (Figs. 9���13). Tibia with stiff setae, with a large unciform prolateral apophysis, curving retrolaterally. Paracymbium simple without apophyses or hairs, with a narrow base. Cymbium with a dorsal depression that accommodates the terminal section of the tibial apophysis. Suprategular apophysis with a bifid marginal apophysis, and a curved widened terminal lobe. Anterior radical process a sharpened process that points out frontally, posterior radical process a filiform ventral process, in close contact with the embolus. Embolus coiling backwards while descending in front of tegulum. Female. Total length 1.63 (1.50���1.75). Prosoma 0.72 (0.70���0.75) long, 0.51 (0.47���0.53) wide. Clypeus not protruding. Anterior row of eyes recurved. Posterior row procurved. AME separated from ALE by the diameter of the former. AME separated by their diameter. PME separated from AME by the diameter of the former. PLE touching ALE. PME separated by half their diameter. PME separated from PLE by half their diameter. Coloration of prosoma and legs yellowish to brown. Sternum slightly darker. Chelicerae with 5 to 7 small stridulatory striae, with four promarginal teeth and five smaller retromarginal denticles. Opisthosoma as in the male (see above). Leg spination as in the male. Tm IV present. Tm I values (for 5 females): 0.51 (0.49���0.57). Measurements of legs in Table 4. Epigynum (Figs. 15, 16). Ventral plate wide, unsclerotized, divided slightly by epigynal folds, which converge anteriorly. Dorsal plate nearly triangular, in ventral view visible for its greater part by reduction of the ventral plate. Receptacula U-shaped, with coiled slender copulatory ducts. Ecology. This species dwells only at the soil stratum of the largest Natural Reserve of S��o Jorge (Topo). Specimens were solely collected by the use of pitfall traps and never by direct hand sampling. The dominant habitat in Topo is the Juniperus brevifolia high altitude cloud forest. Endemic trees, such as Juniperus brevifolia or Ilex perado subsp. azorica are present but do not form large forested areas, the trees being spread in patches with some open spaces with natural hyper-humid grassland. Several small streams cross the area. Phenology. Adults of both sexes were collected in August and September. This might not represent its phenology. No sampling was made in the island of S��o Jorge in other months. Distribution. The island of S��o Jorge, and most precisely, the Topo Natural Reserve., Published as part of Crespo, Lu��s Carlos, Bosmans, Robert, Cardoso, Pedro & Borges, Paulo A.

Borges et al. leg.). All cited material is deposited at EDTP. Diagnosis. The males of this species differ from S. topographicus n. sp. by the anterior radical process sensu Hormiga (2000), which is long, thin, pointing out in a roughly 45 �� angle from the base of the radix, by the straight embolus with a slightly curved tip and by the tibial apophysis, which shows a dorsal widening process hump in its prolateral side. The females can be diagnosed by the wide undivided dorsal plate of the epigynum, and by the shape of the copulatory ducts. The apical position of the metatarsal trichobotria appears to be unique in the Savignia - group (Tm I 0.81 (0.74���0.85)). Redescription. Male. Total length 1.70 (1.60���1.75). Prosoma 0.85 (0.83���0.87) long, 0.59 (0.57���0.60) wide. Male cephalic area slightly elevated, without tubercles or sulci (Fig. 6). Clypeus protruding. Anterior side of prosoma with small hairs. Anterior row of eyes recurved. Posterior row procurved. AME separated from ALE twice the diameter of the former. AME separated by half their diameter. PME separated by four times their diameter. PLE touching ALE. PME separated from AME roughly four times the diameter of the former. PME separated from PLE 1.5 times the diameter of the former. Coloration of prosoma and legs yellowish to brown. Sternum slightly darker. Chelicerae with 15 to 20 imbricated stridulatory striae, with four promarginal teeth and five smaller retromarginal denticles. Opisthosoma with a dorsal pattern of black patches along its dorsal side in a whitish background and black areas along the sides reaching the spinnerets, this pattern being variable to an extent where some specimens present one single large black patch with non-pigmented areas in its center. Legs with a basal and apical spine on tibiae I and II, and one basal on tibiae III and IV (2211). L Sp Ti I���II = 0.4; L Sp Ti III���IV = 1.6. Patellar apical spine present on all legs. Tm IV present. Measurements of legs in Table 1. Male palp (Figs. 1���5). Tibia with three trichobothria, and a large unciform apophysis extending prolaterally, curving retrolaterally. Halfway its length with a flag-like extension. Paracymbium simple without apophyses or hairs, with a wide base. Cymbium with a smooth dorsal depression accommodating the terminal section of the tibial apophysis. Suprategular apophysis with a bifid marginal apophysis and a curved sharpened terminal lobe. Radix with two apophyses, the anterior radical process a thin, long process pointing ventrally in a 45 �� angle direction in regard to the radix���s base, the posterior radical process a stout, short ventral process, in close contact with embolus. Embolus short, descending straight in front of tegulum. Female. Total length 1.89 (1.75 ���2.00). Prosoma 0.83 (0.83 ��� 0.83) long, 0.59 (0.57���0.60) wide. Clypeus not protruding. Anterior row of eyes recurved. Posterior row procurved. AME separated from ALE by the diameter of the former. AME separated by half their diameter. PME separated from AME roughly 1.5 times the diameter of the former. PLE touching ALE. PME separated by their diameter. PME separated from PLE by their diameter. Coloration of prosoma and legs yellowish to brown. Sternum slightly darker. Chelicerae with about five to seven small stridulatory striae, with five promarginal teeth and five smaller retromarginal denticles. Opisthosoma same as in male (see above). Leg spination same as in male. Tm IV present. Tm I values (for 10 females): 0.81 (0.74���0.85). Measurements of legs in Table 2. Epigynum (Figs. 7, 8). Dorsal plate wide and rectangular, in ventral view visible for its greater part by the reduction of the ventral plate. Receptacula J-shaped, with short thick copulatory ducts. Ecology. This species dwells in the canopy of endemic bushes and trees such as Ilex perado subsp. azorica, Vaccinium cylindraceum, Laurus azorica, Erica azorica and Juniperus brevifolia. In the latter species, it is the most abundant endemic spider species. Juniperus brevifolia has numerous short leaves, which provide refuge for the spiders. Using the Lloyd Index (see Ribeiro et al. 2005) this species could be considered as specialist of the endemic tree Juniperus brevifolia. The related gymnosperm exotic tree Cryptomeria japonica is also an important habitat for this spider, particularly at high altitudes when C. japonica is planted as a monoculture near native forests. Phenology. Adults of both sexes are continually found from June to September. This might not represent its phenology as no sampling was carried out in other months. Distribution. Azorean islands with patches of native forest and possible extinct in the remaining islands (Corvo and Graciosa)., Published as part of Crespo, Lu��s Carlos, Bosmans, Robert, Cardoso, Pedro & Borges, Paulo A.

Abstract: We provide the first overview on spiders living in subterranean habitats in Europe, including the first European subterranean spider checklist. In Europe, there are 486 spider species known to dwell in caves and other subterranean habitats, distributed across 22 families. Despite a few species being able to colonize caves across the whole continent, approximately 90% of the species show a restricted distribution, occurring exclusively in one or two countries. From a biogeographic perspective, southern Europe emerges as the main hot spot of subterranean spider diversity, showing the highest richness of endemic species. Compared to other temperate regions of the world, some families appear to be well represented and other poorly represented (or lacking) in European subterranean habitats. Overall, it appears that the taxonomical knowledge on subterranean spiders in Europe is sufficient, but not evenly distributed. As this checklist represents a useful baseline for advances in this field, we point out specific areas of interest for future research. [ABSTRACT FROM AUTHOR]

Background The IUCN Red List of Threatened Species is the most widely used information source on the extinction risk of species. One of the uses of the Red List is to evaluate and monitor the state of biodiversity and a possible approach for this purpose is the Red List Index (RLI). For many taxa, mainly hyperdiverse groups, it is not possible within available resources to assess all known species. In such cases, a random sample of species might be selected for assessment and the results derived from it extrapolated for the entire group - the Sampled Red List Index (SRLI). The current contribution is the third in four papers that will constitute the baseline of a future spider SRLI encompassing 200 species distributed across the world. New information A sample of 200 species of spiders were randomly selected from the World Spider Catalogue, an updated global database containing all recognized species names for the group. The 200 selected species where divided taxonomically at the family level, and the familes were ordered alphabetically. In this publication, we present the conservation profiles of 58 species belonging to the famillies alphabetically arranged between Oecobiidae and Salticidae, which encompassed Oecobiidae, Oonopidae, Orsolobidae, Oxyopidae, Palpimanidae, Philodromidae, Pholcidae, Pisauridae, Prodidomidae and Salticidae.
