Spinel lherzolite xenoliths from the Sant Corneli volcano (Catalan Volcanic Zone, NE Spain) carry the geochemical imprint of melt/rock reaction events that have affected the subcontinental lithospheric mantle (SCLM) beneath the northeastern Iberian margin. Trace element signatures of clinopyroxene indicate that this volume of the SCLM initially experienced low degrees (F = 8 %) of partial melting, followed by extensive refertilization by alkaline silicate melts undergoing chromatographic fractionation while percolating through the mantle peridotites. Furthermore, the presence of interstitial sulphide-bearing silicate glass, as well as secondary coronitic rims around mantle minerals, records the melt/rock reaction product associated with the infiltration of the host alkaline basalts while erupting to the surface. Abundant irregular/blocky sulphides located within the interstitial glass patches are comprised of myrmekitic intergrowths of pentlandite ± bornite ± chalcopyrite, suggesting their derivation from immiscible droplets of Fe-Ni-Cu sulphide melt transported by the host alkaline basalts. The variable chondrite-normalized platinum-group element (PGE) systematics and chalcogenes (Se, Te, As, Bi and Sb) abundances of these sulphides track two distinct transport mechanisms for their parental sulphide melts: 1) by unmixing of Ni-Cu-rich sulphide liquid in alkaline basalts attaining sulphide-saturation while interacting with the peridotite xenoliths, and 2) by mechanical transport of immiscible droplets of Ni-Cu-rich sulphide liquid originally extracted by residual monosulphide solid solution undergoing incongruent melting in their mantle source. In addition, many sulphides have PGE abundances that cannot be explained solely by solid-melt chemical partition coefficients but that were likely influenced by the mechanical entrapment, or earlymagmatic segregation, of pre-existing PGE-rich nanoparticles or nanomelts.

Entre el segle XVII i mitjan segle XIX la nissaga Salvador, apotecaris i naturalistes de Barcelona, van aplegar un gabinet d’història natural que inclou llibres, herbaris, minerals, fòssils, conquilles, espècimens naturals, vestigis arqueològics, peces d’antiquari i cartes. Aquest gabinet el va iniciar el naturalista i farmacèutic Joan Salvador i Boscà al segle XVII, i fou conservat i enriquit pels seus descendents fins ben entrat el segle XIX. El conjunt es trobava a l’apotecaria Salvador del carrer Ample de Barcelona però, cap al 1876 o 1877, fou dut al castell (o masia) de la Bleda (avui al terme de Castellet i la Gornal) on va romandre fins al seu trasllat a l’Institut Botànic de Barcelona el 1938, completat el 2013. A partir d’aquesta recuperació s’han catalogat l’herbari i la biblioteca, restaurat el mobiliari i revisat i restaurat la major part de les col· leccions i una part dels documents.

This archive was started by the naturalist and pharmacist Joan Salvador i Boscà in the 17th century, and was preserved and enriched by his descendants well into the 19th century. The collection was housed in the Salvador apothecary on Carrer Ample in Barcelona but, around 1876 or 1877, it was taken to the castle (or farmhouse) of Bleda (today in the district of Castellet i la Gornal) where it remained until its transfer to the Botanical Institute of Barcelona in 1938, completed in 2013.

The Xerces Blue (Glaucopsyche xerces) is considered to be the first butterfly to become extinct in historical times. It was notable for its chalky lavender wings with conspicuous white spots on the ventral wings. The last individuals were collected in their restricted habitat, in the dunes near the Presidio military base in San Francisco, in 1941. We sequenced the genomes of four 80- to 100-year- old Xerces Blue, and seven historical and one modern specimens of its closest relative, the Silvery Blue (Glaucopsyche lygdamus). We compared these to a novel annotated genome of the Green-Underside Blue (Glaucopsyche alexis). Phylogenetic relationships inferred from complete mitochondrial genomes indicate that Xerces Blue was a distinct species that diverged from the Silvery Blue lineage at least 850,000 years ago. Using nuclear genomes, both species experienced population growth during the Eemian interglacial period, but the Xerces Blue decreased to a very low effective population size subsequently, a trend opposite to that observed in the Silvery Blue. Runs of homozygosity and deleterious load in the former were significantly greater than in the later, suggesting a higher incidence of inbreeding. These signals of population decline observed in Xerces Blue could be used to identify and monitor other insects threatened by human activities, whose extinction patterns are still not well known., The Xerces Blue (Glaucopsyche xerces) is considered to be the first butterfly to become extinct in historical times.

The Fuerteventura Basal Complex comprises Oligocene and Miocene ultra-alkaline-carbonatitic magmatic pulses with outcrops that extend across kilometer-scale areas in some specific sectors of this oceanic island. Additionally, there is evidence of associated weathering materials that affect these magmatic lithologies. These alkaline magmatic rocks (including trachytes, phonolites, syenites, melteigites, and ijolites), carbonatites, and their associated weathering products underwent a preliminary evaluation of rare Earth element (REE) contents based on mineralogical and geochemical studies. REE concentrations in carbonatites of about 10 300 ppm REY (REEs plus yttrium) have been detected in volumes comparable to other locations hosting significant deposits of these critical elements worldwide. Conversely, alkaline magmatic rocks and the resulting weathering products display limited REE contents. Notably, REEs in carbonatites are associated with primary accessory phases such as REEbearing pyrochlore and britholite and secondary monazite. The results obtained in the carbonatites of Fuerteventura underscore the interest in studying the concentrations of critical elements, such as REEs, within a non-conventional geological setting like oceanic islands. However, due to intricate structural attributes, the irregular distribution of these mineralizations, and possible land use and environmental constraints, additional future detailed investigations are imperative to ascertain the real potential of these REE concentrations., The Fuerteventura Basal Complex comprises Oligocene and Miocene ultra-alkaline-carbonatitic magmatic pulses with outcrops that extend across kilometer-scale areas in some specific sectors of this oceanic island.

A growing number of studies suggest that individuals can develop long-term foraging specializations independently of phenotypic or environmental variation, yet little is known about how the foraging niche is acquired. The early learning of the foraging niche hypothesis suggests a key role of vertical cultural transmission in shaping the foraging niche of vertebrates. In birds, direct evidence from natural conditions is limited to a single study that cross-fostered two related species. To date, no study has tested whether the diet received as an offspring determines the diet delivered as a parent within a single species. We tested the early learning of the foraging niche hypothesis using a Mediterranean population of great tits Parus major, which show great diet variability and moderate consistency in the diet they provide to their offspring across years. To do this, we recorded prey delivered to 9–14 day-old chicks over twelve years. Then we assessed vertical transmission of dietary specialization using data (percentage of caterpillars, spiders, and other prey types, as well as mean prey size) from individuals recorded as a chick and as an adult. We standardised the data to control for environmental factors and ran a Linear Model for each prey type to measure individuals' consistency within the group (relative consistency), correlating the diet they received as a chick and the one they provided to their own chicks at the adult stage. The correlations between the diet received as a chick and the diet provided as a parent were either not significant or negative. Hence, although individuals showed relatively consistent foraging niches across years regarding their parental provisioning behaviour, these diet preferences were not correlated to the diet they received in the nest. Further research is needed to determine whether the foraging niche is acquired during the post-fledgling stage., A growing number of studies suggest that individuals can develop long-term foraging specializations independently of phenotypic or environmental variation, yet little is known about how the foraging niche is acquired.

Exploring natural materials offers countless opportunities for inclusive science. At the Museu de Ciències Naturals de Barcelona (Natural Science Museum of Barcelona), we know that looking closely at real materials creates a very valuable context for promoting an understanding of the world and nature, and, therefore, learning sciences. However, getting natural materials to stimulate scientific learning invariably means mobilising teaching strategies that reach all children. These approaches need to spark pertinent questions, generate interest in developing and checking hypotheses, encourage comparing and searching for explanations. They should also enrich relationships between children and the materials and also between peers. Based on exploring natural materials of animal, plant and geological origin, we raise concerns and questions, stimulate hypotheses, look for evidence and compare ideas about aspects that captivate our interest., Exploring natural materials offers countless opportunities for inclusive science.

Animals use colours, morphological structures and behaviour to advertise their dominance status and ability to obtain resources (Resource Holding Potential, RHP) in agonistic contexts with conspecifics. Dominance relationships are also known between species, although the interactions and the information used to assess the other species' RHP remain obscure and empirical evidence of interspecific recog nition of status is hard to obtain. Using behavioural inference is particularly im portant when a species needs to assess the potential loss of fitness in terms of reproduction or survival (e.g., risk of damage or predation) that could be inflicted by another species acting as a predator, parasite or competitor. Our study shows for the first time the existence of interspecific recognition of status signals: Blue tits Cyanistes caeruleus (subordinate species) perceive Great tits Parus major (dominant species) as threats as hole-nesting competitors, and respond differently based on the size of the great tit's black tie stripe. Blue tits seemed to recognize the mean ing of great tits' black ties because they were bolder when defending their nests against small-tie (less dominant) great tits than when repelling attacks by large-tie (more dominant) great tit males. Our results stress that behavioural inference can potentially be used to assess the meaning of status signals that presumably evolved in an intraspecific signalling context., Animals use colours, morphological structures and behaviour to advertise their dominance status and ability to obtain resources (Resource Holding Potential, RHP) in agonistic contexts with conspecifics.

Spinel lherzolite xenoliths from the Sant Corneli volcano (Catalan Volcanic Zone, NE Spain) carry the geochemical imprint of melt/rock reaction events that have affected the subcontinental lithospheric mantle (SCLM) beneath the northeastern Iberian margin. Trace element signatures of clinopyroxene indicate that this volume of the SCLM initially experienced low degrees (F = 8 %) of partial melting, followed by extensive refertilization by alkaline silicate melts undergoing chromatographic fractionation while percolating through the mantle peridotites. Furthermore, the presence of interstitial sulphide-bearing silicate glass, as well as secondary coronitic rims around mantle minerals, records the melt/rock reaction product associated with the infiltration of the host alkaline basalts while erupting to the surface. Abundant irregular/blocky sulphides located within the interstitial glass patches are comprised of myrmekitic intergrowths of pentlandite ± bornite ± chalcopyrite, suggesting their derivation from immiscible droplets of Fe-Ni-Cu sulphide melt transported by the host alkaline basalts. The variable chondrite-normalized platinum-group element (PGE) systematics and chalcogenes (Se, Te, As, Bi and Sb) abundances of these sulphides track two distinct transport mechanisms for their parental sulphide melts: 1) by unmixing of Ni-Cu-rich sulphide liquid in alkaline basalts attaining sulphide-saturation while interacting with the peridotite xenoliths, and 2) by mechanical transport of immiscible droplets of Ni-Cu-rich sulphide liquid originally extracted by residual monosulphide solid solution undergoing incongruent melting in their mantle source. In addition, many sulphides have PGE abundances that cannot be explained solely by solid-melt chemical partition coefficients but that were likely influenced by the mechanical entrapment, or earlymagmatic segregation, of pre-existing PGE-rich nanoparticles or nanomelts.

The Catalan Initiative for the Earth BioGenome Project (CBP) is an EBP-affiliated project network aimed at sequencing the genome of the > 40000 eukaryotic species estimated to live in the Catalan-speaking territories (Catalan Linguistic Area, CLA). These territories represent a biodiversity hotspot. While covering less than 1% of Europe, they are home to about one fourth of all known European eukaryotic species. These include a high proportion of endemisms, many of which are threatened. This trend is likely to get worse as the effects of global change are expected to be particularly severe across the Mediterranean Basin, particularly in freshwater ecosystems and mountain areas. Following the EBP model, the CBP is a networked organization that has been able to engage many scientific and non-scientific partners. In the pilot phase, the genomes of 52 species are being sequenced. As a case study in biodiversity conservation, we highlight the genome of the Balearic shearwater Puffinus mauretanicus, sequenced under the CBP umbrella., The Catalan Initiative for the Earth BioGenome Project (CBP) is an EBP-affiliated project network aimed at sequencing the genome of the > 40000 eukaryotic species estimated to live in the Catalan-speaking territories (Catalan Linguistic Area, CLA).

Invasive alien species pose a challenge to ecosystem stability and crop production, so understanding their interactions with the natural communities they invade is cru cial to mitigate negative effects. The oriental chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), is an invasive insect that attacks chestnut trees. It was first recorded in Spain in 2012 and is now presumably present in the majority of chestnut stands in the country. We assessed variation in the abundance of D. kuriphilus galls and the composition of their associated parasitoid community (Hymenoptera: Chalcidoidea) during a 4- year period (2014–2017) in 12 sampling sites in Catalonia (Spain, northeastern Ibe rian Peninsula), and identified which species contributed most significantly to the control of D. kuriphilus.The results show that the abundance of individual parasitoid species varied during the study period and that the number of species increased year after year. There was also a transition in the parasitoid community composition across the years. Our data suggest that the joint action of the non-native parasitoid Torymus sinensis Kamijo and the native T. notatus (Walker) (Hymenoptera: Chalcidoidea: Torymidae) led to the decline of D. kuriphilus until it was no longer considered a pest. Also, the observed pool of parasitoid species ended up being relatively homogeneous across sites over the years, which may be due to the high natural dispersal of these parasit oids (both by active flight and passive wind dispersal)., Invasive alien species pose a challenge to ecosystem stability and crop production, so understanding their interactions with the natural communities they invade is cru cial to mitigate negative effects.

The Montseny brook newt (Calotriton arnoldi), a glacial relict endemic to a small, isolated massif in northeast Spain, is considered the only Critically Endangered urodele in Europe. Its restricted range is divided by a deep valley that acts as an impassable barrier to dispersal, separating two isolated metapopulations (Western and Eastern) that correspond to independent lineages with different evolutionary trajectories, based on genetic and genomic data. Here, we address the ecological differentiation between lineages and discuss its potential effect on the phenotypic distinctness of each lineage. Based on multiple lines of evidence, we formally describe the Western Montseny brook newt as a new subspecies: Calotriton arnoldi laietanus ssp. nov. Finally, our study underscores the importance of considering taxonomic progress in the conservation policies of endangered species, ensuring appropriate management and protection of the newly described taxa, The Montseny brook newt (Calotriton arnoldi), a glacial relict endemic to a small, isolated massif in northeast Spain, is considered the only Critically Endangered urodele in Europe.

Predicting the future abundance and distribution of introduced alien species is crucial to mitigate their impact on ecosystems, but this has been shown to be highly challenging. A good approach to obtain crucial clues to the root causes behind dynamic changes over time and space of invasive species is historical re surveys. Barcelona holds one of the largest densities in Europe of monk parakeets Myiopsitta monachus, a highly successful invasive avian alien species. In this study, we evaluate population size, population growth rates and range expansion across the city, performing periodic nest and chamber counts from detection of the first nest in 1976 to 2022. Population estimates of monk parakeets during the study period showed a steady increase, reaching 6,444 ± 449 individuals in 2022. The population exhibited exponential growth with a mean population growth rate of r = 0.19 per year, which means a population doubling time of 3.7 years. Fur thermore, two phases were evident: the first from 1976 to 1994 with a growth rate of 0.37 and a population doubling time of 1.9 years; and the second from 1999 to 2022 with a growth rate of 0.08 and a time to double the population of nine years. Moreover, we document the expansion of the range during our study through the colonisation of new areas, which fitted to a diffusion model for the whole period. Currently, the growth rate of the invasive monk parakeet population does not appear to be limited by resources, nest availability, disease, or predators and we expect them to continue increasing and expanding their range if no control measures are taken., Predicting the future abundance and distribution of introduced alien species is crucial to mitigate their impact on ecosystems, but this has been shown to be highly challenging.

Una buena manera de obtener pistas cruciales sobre las causas fundamentales de los cambios dinámicos en el tiempo y el espacio de las especies invasoras son los nuevos estudios históricos. Barcelona tiene una de las mayores densidades de Europa de cotorra argentina, Myiopsitta monachus, una especie de ave exótica invasora de gran éxito. En este estudio, evaluamos el tamaño de la población, la tasa de crecimiento demográfico y la expansión del área de distribución en toda la ciudad, realizando conteos periódicos de nidos y cámaras desde que se detectó el primer nido en 1976 hasta 2022. Las estimaciones de la población de cotorra argentina durante el período de estudio mostraron un aumento constante hasta llegar a 6.444 ± 449 individuos en 2022. La población creció exponencialmente con una tasa media de crecimiento demográfico de r = 0,19 por año, lo que significa que el tiempo de duplicación poblacional es de 3,7 años. Además, se podían diferenciar dos fases: la primera de 1976 a 1994, con una tasa de crecimiento de 0,37 y un tiempo de duplicación de la población de 1,9 años, y la segunda de 1999 a 2022, con una tasa de crecimiento de 0,08 y un tiempo para duplicar la población de nueve años. Además, documentamos la expansión del área de distribución durante nuestro estudio mediante la colonización de nuevas áreas, que se ajustó a un modelo de difusión durante todo el período. Actualmente, la tasa de crecimiento de la población de cotorra argentina no parece estar limitada por los recursos, la disponibilidad de nidos, las enfermedades ni los depredadores y prevemos que la especie continúe aumentando y ampliando su área de distribución si no se toman medidas de control.

Rhipidia domestica Osten Sacken is recorded as new to the Iberian Peninsula and its presence is confirmed back at least to 2017. Rhipidia domestica is distributed widely throughout the New World, and is characterized by subpectinate antennae with a distinctive color pattern, combined with distinct thoracic and wing patterns. The two previously known species of Rhipidia from the Iberian Peninsula both have males with bipectinate antennae and differently patterned wings., Rhipidia domestica Osten Sacken is recorded as new to the Iberian Peninsula and its presence is confirmed back at least to 2017.

Natural history collections preserve invaluable taxidermy specimens, which are prone to lightinduced degradation, compromising their historical and educational significance. Restoration of these specimens to their original appearance through chromatic reintegration is imperative. The principle of reversibility mandates interventions that are modifiable or reversible without harming the original work, thereby preserving authenticity and enabling future conservation efforts. This study aims to identify the most suitable product for chromatic reintegration of a mammal taxidermy specimen, evaluate its fidelity to the original population, and assess its imperceptibility to the general public during exhibitions. Various products underwent rigorous evaluation for colouration, drying time, coverage, reversibility, safety, and resistance to light degradation. Accelerated aging tests using the Xenotest were conducted to simulate long-term light exposure. A beech marten taxidermy specimen was restored with the chosen dye, and its colour was compared against skins from the original population of the species. Public perception tests were conducted to gauge the ability of people to detect the chromatic restoration during exhibitions. Orasol® dye emerged as the optimal choice for chromatic reintegration, meeting criteria for colouration, reversibility, coverage, and resistance to light degradation. Despite its toxicity for aquatic organisms, it demonstrated promising results. Most colour measurements closely matched the original beech marten population, with minor hue deviations. Public perception tests confirmed the imperceptibility of the chromatic restoration, indicating its suitability for exhibition and educational purposes. This study highlights the importance of authenticity and imperceptibility in restoration processes, emphasizing the need for meticulous consideration of budget constraints in museum settings., Natural history collections preserve invaluable taxidermy specimens, which are prone to lightinduced degradation, compromising their historical and educational significance.

Gluphisia rurea (Fabricius, 1787) aparece en la península ibérica en dos núcleos separados: uno en la zona cantábrica y otro en Cataluña. Mientras que la población occidental se sitúa preferentemente en el piso colino, por debajo de los 200 m de alti- tud, la oriental muestra preferencia por el piso montano, en cotas comprendidas entre 800 y 1.400 m. En cuanto a la fenología de G. rurea en la península ibérica, los datos recopilados en este artículo confirman que se trata de una especie bivoltina, con una primera generación desde mediados de abril hasta principios de julio y una segunda desde principios de julio hasta mediados de septiembre.

Social associations among conspecifcs are typically non-random, ofen being a function of relatedness, familiarity, or spatial distributions. Te aim of this study was to combine feld observations with molecular genetic techniques and social network analysis to investigate the predictors of social associations in free-living monk parakeets, Myiopsita monachus. Monk parakeets are non-territorial parrots whose nests are ofen aggre gated, with relatives clustered in kin neighbourhoods and within cooperatively breeding groups. First, we characterized social associations when away from the nest, showing that individuals typically had a few strong social ties. Second, we investigated whether these social associations were related to nest proximity or genetic relatedness. Te strength of association decreased with increasing inter-nest distance, but there was negligible infuence of relatedness on the strength of associations. Tese paterns did not difer between same-sex and opposite-sex dyads. Finally, we inves tigated whether members of breeding pairs were close social associates, fnding that in most cases the closest associate of an individual was their mate, although social bonds also existed outside of the pair; members of breeding groups also associated closely when foraging. Social associ ations are poorly known in parrots owing to methodological challenges, hence our results add to the limited knowledge of sociality in this taxon., Social associations among conspecifcs are typically non-random, ofen being a function of relatedness, familiarity, or spatial distributions.

For the first time, an overview is presented of the species of crane flies (Limoniidae and Tipulidae) known from the West Indies, with their distributions in the area that comprise the islands of the Caribbean Sea between the United States, the Isthmus of Panama, and South America. Of the 258 species of crane flies known from the West Indies, 206 are endemic to the West Indies (80%) and 167 (65%) are known from only one island. Records are available for 22 islands, noting that there are islands where crane flies certainly do occur, but which have remained so far without records. Although the Greater Antilles show relatively large numbers of species on each island, there is a high probability of interesting new discoveries because of the size and habitat diversity of these islands. The Lesser Antilles have some islands that are well researched, but the fauna of most islands is incompletely known at best, and completely unknown for some. In addition to an updated list of the known species, we include several new records, distribution tables, and images of wings for the genera/subgenera. We also offer the island references which pertain to each species, and present a list of the regional keys that are available for species identification., For the first time, an overview is presented of the species of crane flies (Limoniidae and Tipulidae) known from the West Indies, with their distributions in the area that comprise the islands of the Caribbean Sea between the United States, the Isthmus of Panama, and South America.

Human-mediated habitat destruction has had a profound impact on increased species extinction rates and population declines worldwide. The coastal development in the United Arab Emirates (UAE) over the last two decades, serves as an example of how habitat transformation can alter the landscape of a country in just a few years. Here, we study the genomic implications of habitat transformation in the Critically Endangered Emirati Leaf-toed Gecko (Asaccus caudivolvulus), the only endemic vertebrate of the UAE. We generate a high-quality reference genome for this gecko, representing the first refer ence genome for the family Phyllodactylidae, and produce whole-genome resequencing data for 23 specimens from 10 different species of leaf-toed geckos. Our results show that A. caudivolvulus has consistently lower genetic diversity than any other Arabian species of Asaccus, suggesting a history of ancient population declines. However, high levels of recent inbreeding are recorded among populations in heavily developed areas, with a more than 50% increase in long runs of homozygosity within a 9-year period. Moreover, results suggest that this species does not effectively purge deleterious mutations, hence making it more vulnerable to future stochastic threats. Overall, results show that A. caudivolvulus is in urgent need of protection, and habitat preservation must be warranted to ensure the species' survival., Human-mediated habitat destruction has had a profound impact on increased species extinction rates and population declines worldwide.

Se acompaña una relación de todas las especies consideradas saproxílicas y de las que están presentes en los convenios IUCN de los coleópteros saproxílicos de Europa y del Mediterráneo. Se da una descripción somera del Parque Natural, indicando su área, geología, climatología y arbolado presente en las diferentes parcela muestreadas. También se incluye un índice taxonómico y fotos de habitus de diferentes especies colectadas en el área estudiada., Con el fin de profundizar en el conocimiento de la fauna coleopterológica del Parque Natural del Montseny (reserva de la biosfera de la UNESCO), se ha realizado un trampeo sistemático en toda el área del Parque durante tres años (2008 a 2010) y en el 2018 en un hayedo, mediante diferentes metodologías de captura.

Gluphisia rurea (Fabricius, 1787) occurs in the Iberian Peninsula in two discrete nuclei: one in the Basque–Cantabrian zone and the other centred on Catalonia. While the western population shows a preference for the colline zone, below 200 m in alti- tude, the eastern one exhibits a clear preference for the montane zone, at elevations ranging from 800 to 1,400 m. With respect to the phenology of G. rurea in the Iberian Peninsula, the data collected in this article confirm that it is a bivoltine species, with a first generation from mid-April to early July, and a second from early July to the middle of September., Gluphisia rurea (Fabricius, 1787) occurs in the Iberian Peninsula in two discrete nuclei: one in the Basque–Cantabrian zone and the other centred on Catalonia.
