Abstract: The identity and phylogenetic relationships of Laetiporaceae taxa (Polyporales, Basidiomycota) remain poorly studied. In this work we carry out a multigene phylogenetic analysis to identify the Laetiporus species that grow in South America and move forward the understanding of the phylogenetic relationships among the poroid genera of Laetiporaceae within the antrodia clade. Based on the morphology and molecular phylogenetic data, two new genera are proposed, Berckurtia to accommodate Berkcurtia persicina comb. nov. and Atlantiporus to accommodate Atlantiporus squalidus comb. nov., and 2 other new combinations Kusaghiporia talpae and Laetiporus dilatohyphus. A key to the poroid genera of the Laetiporaceae is also provided and the taxonomic implications for these species and related taxa are discussed.

3. New insights on Bjerkandera (Phanerochaetaceae, Polyporales) in the Neotropics with description of Bjerkandera albocinerea based on morphological and molecular evidence

Author: Viviana Motato-Vásquez, Adriana Gugliotta, Mario Rajchenberg, Myriam Catania, Carlos Urcelay, and Gerardo Robledo
Subjects: cryptic species, Neotropical polypores, phylogeny, Plant ecology, QK900-989
Abstract: Background and aims – Bjerkandera is one of the few poroid genera in the Phanerochaetaceae family known to date. The genus has a worldwide distribution and is characterized by effused-reflexed, pileate basidiomata with a pale cream to smoky or mouse grey hymenophore that becomes darker when dried, and a monomitic hyphal structure with clamped generative hyphae. Morphological and phylogenetic studies have traditionally accepted only two species in the genus, B. adusta (generic type) and B. fumosa, both described from temperate Europe. Recently, three additional species, B. atroalba, B. centroamericana and B. mikrofumosa were described from the Neotropics. While studying polypores in the Yungas forests of northwest Argentina and the Atlantic Forest of southeast Brazil, several specimens of Bjerkandera were gathered. A comparative morphological study revealed that some of these specimens do not correspond to any of the known species in the genus. This study aimed to propose a broad species-level phylogenetic hypothesis for Bjerkandera in the Neotropics and worldwide and to discuss the taxonomic status and diversity of the species in this genus.Methods – This study is based on a morphological examination of specimens collected between 2012 and 2017, and on a revision of original collections, including the type specimens. A total of eleven ITS and seven nLSU sequences were generated and phylogenetic analyses based on Bayesian Inference (BI) and Maximum Likelihood (ML) were performed.Key results – An extensive documentation of the species diversity within Bjerkandera in the Neotropics is presented. Genetic data of B. mikrofumosa were obtained for the first time and its phylogenetic position was tested. Additionally, its geographic distribution was extended in the Neotropics to Argentina and Brazil. Finally, molecular and morphological evidence was used to propose a new species for the genus, Bjerkandera albocinerea sp. nov.Conclusion – This study provides an update of the known diversity of the genus in the Neotropics and worldwide. In addition, our results indicate that the number of taxa in Bjerkandera has been underestimated by morphological evidence, and may actually be greater than traditionally accepted.

4. El 'siempreverde' (Ligustrum lucidum), ¿Altera la composición de las comunidades de hongos micorrícicos arbusculares en el Chaco Serrano?

Author: Valentina Borda, M. Noelia Cofré, Silvana Longo, Gabriel Grilli, and Carlos Urcelay
Subjects: planta invasora leñosa, grupos funcionales de hongos, propiedades del suelo, simbiosis, Environmental sciences, GE1-350, Ecology, QH540-549.5
Abstract: Las invasiones biológicas representan una gran amenaza para la biodiversidad y la integridad de los ecosistemas dado que alteran las comunidades bióticas. Entre las comunidades bióticas del suelo se destacan los hongos micorrícicos arbusculares (HMA), que establecen asociaciones simbióticas con la mayoría de las plantas terrestres. Las especies de HMA no responden del mismo modo a los cambios ambientales, por lo que se propuso la existencia de grupos de especies de HMA con estrategias ecológicas compartidas (ruderales, competidoras y estrés tolerantes). Las plantas invasoras son capaces de alterar las comunidades de HMA para su propio beneficio. Este podría ser el caso del “siempreverde” (Ligustrum lucidum), un árbol asiático que invade numerosos sectores de la Argentina y forma, en algunas zonas, bosques monoespecíficos densos. En este estudio se compararon las comunidades de esporas de HMA entre bosques monoespecíficos de siempreverde y bosques chaqueños serranos nativos. Se seleccionaron 6 áreas con ambos tipos de bosque. De cada área se tomaron muestras de suelo, a las que se les midieron características físico-químicas y se les extrajeron las esporas de HMA. De acuerdo con lo esperado, la composición de las comunidades de esporas de estos bosques monoespecíficos fue diferente a la presente en suelos de bosques nativos. La riqueza de morfoespecies de esporas de HMA no mostró diferencias entre ambos tipos de bosque, pero la abundancia total fue mayor en los suelos de bosque de siempreverde, que presentan un mayor número de esporas de especies ruderales. Este estudio provee evidencia que sugiere que la expansión del siempreverde altera las comunidades de esporas de HMA y algunas propiedades químicas del suelo. Estos cambios posiblemente sean parte del mecanismo que promueve la formación de bosques monoespecíficos.

5. Neotropical Studies on Hymenochaetaceae: Unveiling the Diversity and Endemicity of Phellinotus

Author: Carlos A. Salvador-Montoya, Samuel G. Elias, Orlando F. Popoff, Gerardo L. Robledo, Carlos Urcelay, Aristóteles Góes-Neto, Sebastián Martínez, and Elisandro R. Drechsler-Santos
Subjects: three new taxa, endemic fungi, phylogenetic lineages, SDTF species, taxonomy, xanthocroic polypores, Biology (General), QH301-705.5
Abstract: Phellinotus, a neotropical genus of wood-decay fungi commonly found on living members of the Fabaceae family, was initially described as containing two species, P. neoaridus and P. piptadeniae. The members of this genus, along with six other well-established genera and some unresolved lineages, are the current representatives of the ‘phellinotus clade’. On the other hand, based on a two-loci phylogenetic analysis, some entities/lineages of the ‘phellinotus clade’ have been found in Fomitiporella s.l. In this work, we performed four-loci phylogenetic analyses and based on our results the genera of the ‘phellinotus clade’ are shown to be monophyletic groups. In addition to the natural groups confirmed as different genera, morphological revisions, phylogenetic relationships, and host distribution of different specimens resembling P. neoaridus and P. piptadeniae revealed three new species in the Phellinotus genus, referred to here as P. magnoporatus, P. teixeirae and P. xerophyticus. Furthermore, for P. piptadeniae a narrower species concept was adopted with redefined morphological characters and a more limited distribution range. Both P. neoaridus and P. teixeirae have a distribution range restricted to seasonally dry tropical forests in South America. Additionally, based on detailed morphological revisions Phellinus badius, Phellinus resinaceus, and Phellinus scaber are transferred to the Phellinotus genus. The geographic distribution and host range of the genus are then discussed.

6. Evaluación de la restauración de la diversidad fúngica en un área reforestada con Polylepis australis (Rosaceae): un estudio de caso

Author: Ana L. Gallo, Gerardo L. Robledo, Marcos Landi, and Carlos Urcelay
Subjects: hongos, macromicetes, riqueza, abundancia, equitatividad, reforestación, bioindicadores, argentina, Environmental sciences, GE1-350, Ecology, QH540-549.5
Abstract: Los bosques de Polylepis australis han sido muy disturbados y la reforestación es una alternativa para restaurar esos ecosistemas. El objetivo del presente estudio es evaluar la restauración de la comunidad fúngica en un bosque de P. australis reforestado. Nuestra hipótesis de trabajo es que la comunidad fúngica se modifica en concordancia con las situaciones del bosque: alta degradación, bosque natural maduro y bosque restaurado. Se compararon variables fúngicas (riqueza, abundancia y equitatividad de macromicetes) de un área nativa, de un área degradada y reforestada y de un área degradada sin reforestación. Para ello se establecieron 15 parcelas de 5x5 m y se muestrearon cinco por estación. Se recolectaron las fructificaciones de macromicetes, y luego se las clasificó en grupos morfo-taxonómicos. Se hicieron análisis de componentes principales y de correlación entre las variables fúngicas y la estructura vegetal, y análisis de correlación entre las variables fúngicas y las variables químicas del suelo. La riqueza, la abundancia y la equitatividad fueron significativamente mayores en el área nativa, intermedias en el área reforestada y menores en el área degradada. Las parcelas del área nativa se caracterizaron por una alta cobertura de árboles maduros, las del área reforestada por graminoides y árboles jóvenes y las del área degradada por herbáceas latifoliadas. Las tres variables fúngicas fueron máximas a mayor cobertura arbórea y correlacionaron positivamente con el fósforo y pH del suelo. Los resultados muestran que 12 años después de que un área degradada fuera reforestada con P. australis, la diversidad fúngica es mayor que la de un área degradada, pero está lejos de alcanzar los niveles del área nativa. Se postula que los hongos serían bioindicadores sensibles a la degradación y la restauración de los bosques.

7. El potencial de colonización micorrícico-arbuscular varía entre prácticas agrícolas y sitios en diferentes áreas geográficas de la Región Pampeana

Author: Noelia Cofré, Carlos Urcelay, Luis G. Wall, Laura Domínguez, and Alejandra Becerra
Subjects: Environmental sciences, GE1-350, Ecology, QH540-549.5
Abstract: Para evaluar las comunidades fúngicas es necesario identificar las especies presentes, cuantificar la densidad de propágulos y también determinar su infectividad. En este estudio se evaluó, mediante un ensayo experimental, el potencial de colonización micorrícico-arbuscular (PCM) de tres suelos bajo diferentes sistemas de cultivo (pastizal natural, rotación de cultivo y monocultivo de soja en siembra directa), en cuatro sitios ubicados en diferentes áreas geográficas de la Región Pampeana (Bengolea, Monte Buey, Pergamino y Viale), y se usó a Vicia villosa Roth como planta testigo. Los usos del suelo y los sitios tuvieron efecto sobre el PCM. Como esquema de rotación, el monocultivo mostró el mayor potencial para colonizar las raíces de Vicia villosa con respecto al pastizal natural, y la rotación de cultivo en la mayoría de las combinaciones planteadas, a diferencia de lo encontrado antes para los mismos suelos, donde el monocultivo disminuyó la riqueza de las comunidades micorrícicas determinadas por la densidad y la diversidad de esporas. Estos resultados remarcan las limitaciones de los paradigmas de interpretación de los sistemas simbióticos generados a partir de ensayos en condiciones controladas y el gran desconocimiento que aún existe sobre el funcionamiento de las interacciones planta-microorganismo en el suelo. Alternativamente, estos resultados podrían ser consecuencia de un efecto inhibitorio de la mayor fertilidad N-P en los suelos con rotación de cultivo respecto de los suelos bajo monocultivo debido a un manejo de reposición histórica de nutrientes por fertilización, ausente en los casos de monocultivo. El uso de una única especie vegetal en los ensayos de infectividad también podría estar sesgando los resultados, ya que limitaría, por especificidad de hospedador, su expresión en la totalidad de la comunidad micorrícica del suelo. https://doi.org/10.25260/EA.18.28.3.0.696

Abstract: En ecosistemas áridos y semiáridos las raíces de las plantas suelen formar simbiosis con hongos, los que les proporcionan nutrientes y agua. Poco se conoce sobre los hongos asociados a palmeras nativas y cómo éstos podrían estar relacionados entre ellos. Se describe y cuantifica la colonización radical de los simbiontes de Trithrinax campestris en poblaciones leve y fuertemente afectadas por el fuego. T. campestris fue colonizada por hongos micorrícico-arbusculares (HMA) y endófitos septados oscuros (ESO). La colonización por HMA fue del tipo intermedio entre los tipos Arum y Paris. La colonización por HMA y ESO y la producción de pelos radicales, presentó diferencias entre las poblaciones estudiadas. Los resultados sugieren que en T. campestris la relación entre hongos simbiontes/producción de pelos radicales podrían estar relacionada con su alta tolerancia al fuego y la aridez.In arid and semiarid ecosystems, roots frequently form symbiosis with fungi that provides access to nutrients and water. Knowledge regarding the study of fungal symbionts colonizing native palms roots is still scarce. We described, quantified and compared fungal colonization in roots of Trithrinax campestris from two environmental situations: population with weak-burning-signs and population with strong-burning-signs. T. campestris was colonized by arbuscular-mycorrhizal-fungi (AMF) and dark-septate-endophytes (DSE). AMF colonization was an intermediate type between Arum and Paris. The AMF and DSE colonization and root hair production differed between populations. Our results suggest that in T. campestris the relation between fungal-symbionts and root-hair-production might be related to tolerance to burning and aridity.

Abstract: Se estudió la colonización de las raíces por simbiontes fúngicos en Miconia ioneura y Tibouchina paratropica (Melastomataceae). Se observaron y describen estructuras micorrícicas arbusculares pertenecientes a los tipos 'Paris' (hifas y rulos intracelulares) y 'Arum' (hifas intercelulares y arbúsculos). Además se observaron endófitos septados oscuros (hifas y esclerocios). Se registra por primera vez la ocurrencia de ambos tipos micorrícicos arbusculares y de endófitos septados oscuros en raíces de especies pertenecientes a la familia Melastomataceae. Se discuten las implicancias ecológicas y evolutivas de la ocurrencia simultánea de los distintos tipos de colonización micorrícica en raíces de la misma especie.The roots of Miconia ioneura and Tibouchina paratropica (Melastomataceae) were studied for fungal symbionts colonization. Typical structures of 'Paris' (intracellular hyphae and coils) and 'Arum' (intercellular hyphae and arbuscules) arbuscular mycorrhizal types were observed and are described here. Dark septate fungi (hyphae and sclerotia) were also observed. The occurrence of both types of arbuscular mycorrhizal colonisation and dark septate fungi in the roots of species belonging to Melastomataceae is reported for the first time. The possible ecological and evolutionary implications of the co-occurrence of these mycorrhizal colonisation types in the same species are discussed.

Subjects: graminoides, dicotiledóneas anuales, dicotiledóneas perennes, micorrizas arbusculares, Environmental sciences, GE1-350, Ecology, QH540-549.5
Abstract: En el centro de Argentina se han realizado numerosos estudios evaluando la relación entre distintos tipos funcionales de plantas (TFPs) en función de sus caracteres vegetativos y sus efectos sobre la herbivoría y el funcionamiento ecosistémico. Sin embargo, se desconoce la relación entre TFPs y la colonización micorrícica arbuscular, a pesar de que esta asociación está presente en la mayoría de las plantas vasculares terrestres y tiene influencia en la estructuración de las comunidades vegetales. El objetivo de este trabajo fue evaluar si existen diferencias en la colonización micorrícica arbuscular entre conjuntos de especies herbáceas agrupadas en distintos TFPs establecidos a priori sobre la base de caracteres vegetativos. Para ello cuantificamos la colonización micorrícica en 18 especies herbáceas correspondientes a las más abundantes de tres TFPs herbáceos del arbustal serrano del centro de Argentina, dicotiledóneas anuales, dicotiledóneas perennes y graminoides, dentro de éstas últimas C3 y C4 . Se observaron diferencias significativas en la colonización total y colonización por arbúsculos pero no por vesículas. En particular, las dicotiledóneas no variaron significativamente entre ellas pero mostraron valores de colonización significativamente más altos que las graminoides. En conjunto, nuestros resultados sugieren que la combinación de caracteres vegetativos, probablemente arquitectura radical y asignación de carbono, en herbáceas del centro de Argentina influye en los patrones de colonización por hongos micorrícicos arbusculares.

Abstract: The great majority of plants gain access to soil nutrients and enhance their performance under stressful conditions through symbiosis with arbuscular mycorrhizal fungi (AMF). The benefits that AMF confer vary among species and taxonomic groups. However, a comparative analysis of the different benefits among AMF has not yet been performed. We conducted a global meta-analysis of recent studies testing the benefits of individual AMF species and main taxonomic groups in terms of plant performance (growth and nutrition). Separately, we examined AMF benefits to plants facing biotic (pathogens, parasites, and herbivores) and abiotic (drought, salinity, and heavy metals) stress. AMF had stronger positive effects on phosphorus nutrition than on plant growth and nitrogen nutrition and the effects on the growth of plants facing biotic and abiotic stresses were similarly positive. While the AMF taxonomic groups showed positive effects on plant performance either with or without stress, Diversisporales were the most beneficial to plants without stress and Gigasporales to plants facing biotic stress. Our results provide a comprehensive analysis of the benefits of different AMF species and taxonomic groups on plant performance and useful insights for their management and use as bio-inoculants for agriculture and restoration.

Abstract: Alien invasive trees may expand and form monospecific forests by enhancing mutualism with arbuscular mycorrhizal fungi (AMF) and/or preventing the establishment of other plants through accumulation of antagonists for native plants. The success of invasive plants also has been associated with their higher phenotypic plasticity. Here we tested these mechanisms by studying the global invasive tree Ligustrum lucidum (hereafter Ligustrum) and the dominant native tree of the Chaquean montane forest (central Argentina) Lithraea molleoides (hereafter Lithraea). We experimentally addressed the effects of soil biota from Ligustrum monospecific forest stands and native montane forests on growth, biomass allocation, and nutrition of alien Ligustrum and native Lithraea. Soil biota was recovered from the rooting zone of adult trees of both species in each forest type. We found that arbuscule colonization in Ligustrum roots was significantly higher in seedlings grown with AMF communities from monospecific invaded forests in comparison to native soils. Mycorrhizal colonization in Lithraea roots did not differed between forest types. Soil biota from the rooting zone of the native Lithraea had no major effects on both itself and the invasive Ligustrum. Instead, AMF from Ligustrum rooting zone almost tripled and doubled P nutrition of the alien and the native compared with non-AMF treatments, respectively. Besides, antagonistic effects of soil biota were not observed. Lithraea root mass fraction (root mass/total plant mass, RMF) was not affected by forest type nor by soil treatment but Ligustrum RMF was affected by both factors. In particular, RMF decreased when seedlings grew with AMF from its rooting zone. The observed positive plant–soil feedback and the phenotypic plasticity of Ligustrum could explain, at least in part, the high invasiveness and the formation of monospecific forest stands by this global invader.

Abstract: Changes in soil biota following fire and its successive influence on their interactions with plants may have direct implications on the invasion successof woody alien species in fire-prone ecosystems. In this work, we experimentally addressed if soil biota from burned and unburned areas differentially affectgrowth and nutrition of two dominant woody natives (Lithraea molleoides and Vachellia caven) and three woody invaders (Gleditsia triacanthos, Ligustrumlucidum and Pyracantha angustifolia) that occur on fire-prone ecosystems of central Argentina. Our results indicate that growth and P content in tissuesof both woody natives Lithraea and Vachellia were generally benefited by arbuscular mycorrhizal fungi (AMF) and that these effects did not strongly differ between AMF communities from burned and unburned soils. In the case of alien species, differences in growth and nutrition in response to AMF wererelated more to the identity of the invader than on the provenance of the soil biota. This study provides evidence on the important role that soil biota may have in the success of woody aliens in these ecosystems and on the functional stability of AMF communities facing disturbances.

Abstract: Soil use and management modify mycorrhizal interactions, but how these changes affect the growth and nutrition of crops under different contexts has been poorly studied. The objective of this study was to evaluate the effects of arbuscular mycorrhizal fungal (AMF) spore communities belonging to two no-till cropping systems (soybean monoculture and soybean-maize rotation), and uncultivated grasslands replicated at four locations along a regional geographic gradient on soybean mycorrhizal colonization and performance. At a regional scale, AMF spore richness was higher in uncultivated grasslands, intermediate in crop rotations, and lower in monocultures. Arbuscular mycorrhizal colonization in soybean roots was also higher in uncultivated soils but did not differ between no-tillage systems. Soybean growth was positively affected by AMF from uncultivated grasslands in comparison to control without AMF. Instead, there were no significant effects of AMF from no-till cropping systems. Foliar P concentration was lower in monocultures irrespective of AMF. At the local scale, patterns were highly variable and differed between locations. These results highlight the importance of scales for management decisions in agriculture and add further support for the context-dependent nature of mycorrhizal interactions.

Abstract: Two main soil management practices are generally used for soybean production: monoculture (MC) and crop rotation (CR). These strategies have different impacts on soil microbial communities. Among them, arbuscular mycorrhizal fungi (AMF) are well known to provide access to nutrients in a majority of cultivated plants. AMF communities have been shown to be more diverse in CR than in MC. Because AMF species differ in their effects on nutrition and development of plants, it could be expected that soil biota from different soil management practices affect soybean yield and quality. Therefore the objective of this study was to examine the combined effects of soil microbial communities and soil management practices (MC and CR) on yield, protein content, and oil quality of soybean grown under greenhouse conditions. The effects of three soil treatments, namely: sterile (S); microorganisms without AMF (MO); and microorganisms with AMF (AMF) were evaluated. These treatments were applied to soils from two crop management practices (CR and MC). Sterile soil promoted lower numbers of pods and seed weight per plant in MC but not in CR. AMF showed increased seed protein content (12?14%) whereas MO presented increased oil concentration (20?27%) (mainly within CR). Soybean grown with AMF from CR soil showed significantly higher amounts of oleic acid (21?25%), and lower linoleic acid (9%) when compared with other treatments. Findings from this study suggest that soybean yield and quality are affected by crop management practices and soil biota composition. Further, these parameters should be considered at the time of selecting agricultural strategies. Fil: Marro, Nicolás Alejandro. Consejo Nacional de Investigaciones Científicas y Técnicas.

Abstract: Las invasiones biológicas representan una gran amenaza para la biodiversidad y la integridad de los ecosistemas dado que alteran las comunidades bióticas. Entre las comunidades bióticas del suelo se destacan los hongos micorrícicos arbusculares (HMA), que establecen asociaciones simbióticas con la mayoría de las plantas terrestres. Las especies de HMA no responden del mismo modo a los cambios ambientales, por lo que se propuso la existencia de grupos de especies de HMA con estrategias ecológicas compartidas (ruderales, competidoras y estrés tolerantes). Las plantas invasoras son capaces de alterar las comunidades de HMA para su propio beneficio. Este podría ser el caso del ?siempreverde? (Ligustrum lucidum), un árbol asiático que invade numerosos sectores de la Argentina y forma, en algunas zonas, bosques monoespecíficos densos. En este estudio se compararon las comunidades de esporas de HMA entre bosques monoespecíficos de siempreverde y bosques chaqueños serranos nativos. Se seleccionaron 6 áreas con ambos tipos de bosque. De cada área se tomaron muestras de suelo, a las que se les midieron características físico-químicas y se les extrajeron las esporas de HMA. De acuerdo con lo esperado, la composición de las comunidades de esporas de estos bosques monoespecíficos fue diferente a la presente en suelos de bosques nativos. La riqueza de morfoespecies de esporas de HMA no mostró diferencias entre ambos tipos de bosque, pero la abundancia total fue mayor en los suelos de bosque de siempreverde, que presentan un mayor número de esporas de especies ruderales. Este estudio provee evidencia que sugiere que la expansión del siempreverde altera las comunidades de esporas de HMA y algunas propiedades químicas del suelo. Estos cambios posiblemente sean parte del mecanismo que promueve la formación de bosques monoespecíficos. Fil: Borda, Valentina. Consejo Nacional de Investigaciones Científicas y Técnicas.

Abstract: Diacanthodes (Polyporales, Basidiomycota) is a fungal genus with stipitate basidiomata and a combination of ornamented and dextrinoid basidiospores that is unique among the poroid fungi. Although some hypotheses based on morphological features speculated about the phylogenetic relationships of the taxon, they have never been tested based on molecular data. We performed molecular phylogenetic analyses including specimens of Diacanthodes from the Neotropics and Africa using the internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) and the D1–D2 domains of the 28S gene of the nuclear rDNA regions, as well as the translation elongation factor 1-alpha (TEF-1α) protein-coding gene. Our study revealed Diacanthodes as a member of the ‘core polyporoid’ clade within the Polyporales. Two new species from South America: Diacanthodes cerebriporoides and D. neotropicalis, a new combination D. coffeae from Africa and notes on the other Diacanthodes species are presented. Basidiospore morphology in Diacanthodes and related genera is discussed in the phylogenetic context. Fil: Robledo, Gerardo Lucio. Universidad Nacional de Córdoba.

Abstract: Terrestrial ecologists have identified multifaceted controls-climate, biogeography, disturbances, and their interactions-that shape how plant communities in natural ecosystems organize in space and time. Multiple documented interactions directly link plant diversity with other biotic guilds (herbivores, root symbionts, bacteria, and pathogens) and ecosystem processes [carbon (C) and nutrient cycling] (1). However, all appears to go awry when exotic (non-native) plant species invade and establish themselves without human intervention; such changes affect the functioning and diversity of natural ecosystems (2). On page 967 in this issue, Waller et al. (3) provide insight into pathways that explain the underlying relationship between plant invasions and acceleration of a crucial ecosystem process: C turnover. Fil: Urcelay, Roberto Carlos.

Abstract: Fungi are import organisms in tropical ecosystems. However, there is little information about their community structure and dynamics in these environments. This study aimed to evaluate the structure and presence of indicator species of epigeous Gasteromycetes in distinct ecosystems (lowland rain forest, Araucaria forest, and semideciduous forest) of the Atlantic Forest in southern Brazil. Samplings were carried out during the summer and autumn of 2014 and 2015 involving ten transects (50 × 4 m). Forty-seven species were identified, of which 48% belong to Geastrum. An ANOVA showed a significant difference in diversity of gasteroid fungi among the forest types and the two evaluated seasons. An ordination nonparametric analysis to assess the composition of species of the forest types revealed a stress value of 0.12. In total, 13 species were classified as indicator species by an IndVal analysis. Our results reject our hypothesis, which we infer, that a greater diversity of gasteroid fungi would be in areas of lowland rain forest.In this sense, leading us to rethinking techniques and new approaches for ecological studies of gasteroid fungi in Brazil. However, the study underscores the importance of understanding the relationships of fungal communities in forest environments.

Abstract: On the basis of morphological and molecular analysis of several specimens of Lysurus periphragmoides collected in Argentina, the examination of materials collected in the type locality of Simblum sphaerocephalum (nowadays known as L. periphragmoides), also collected in Argentina (Córdoba), and the examination of specimens of L. periphragmoides from the old world, we conclude that Argentinean and South American material identified and synonymized to L. periphragmoides by Dring in 1980 should be emended as L. sphaerocephalum. As this species lacks type material designated on its protologue, and there is no type material either, we propose a lectotype and an epitype for L. sphaerocephalum. On the basis of species descriptions found in literature, we constructed a table with relevant differences between these two species: L. periphragmoides and L. sphaerocephalum. We fully describe L. sphaerocephalum, including lecto- and epitypes, and its position within the Lysuraceae clade. This work also includes descriptions and images of Blumenavia rhacodes, Itajahya galericulata, L. cruciatus, and Phallus indusiatus from Argentina, with the aim of expanding our knowledge of their distribution ranges in the studied regions.

Abstract: Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

Abstract: This study examined bio-oil and solid products generated from the diatom Melosira varians by fast pyrolysis using a fixed-bed reactor with inert gas flow and a vacuum medium. The effect of temperature (300–700 °C) on product yields, the bio-oil composition and the properties of the solid fraction were evaluated. It was found that the most suitable temperature to obtain significant amounts of high-quality bio-oil (29% yield) was 450 °C, at which point fatty acids appeared as main components. Under all operating conditions a solid material, mainly composed of siliceous frustules, was the most abundant product (59–88% yield). These materials were exhaustively characterized by SEM microscopy, Raman and FT-IR spectroscopy, XRD, elemental analysis and BET surface analyses. The structure and morphology of the biosilica were practically unaltered in the studied temperature range. The conductivity properties of the solids derived from diatom and their composites with carbon nanotubes were determined using cyclic voltammetry. Fil: Piloni, Roxana Verónica.

Abstract: Fungi are organisms with important roles in ecosystem functioning and services, but knowledge about how habitat fragmentation affect fungal diversity is biased by experimental approaches and it is spread in different trophic groups. We analyzed the empirical evidences of fungal diversity in fragmented landscapes, and proposed future perspectives for the study of these organisms under land use changes. Fungal diversity might be negatively affected by habitat fragmentation; however, this trend may differ in magnitude depending on fungal groups and their nutritional habits. In addition, due to the fact that fungal diversity at fragmented landscapes has been studied mainly through few indicators (e.g. isolation, area and edge effect); we propose incorporating the landscape structure and accurate spatio-temporal scales to the study of fungal diversity responses to fragmented landscapes. Together, this methodological refinement may allow improving knowledge on fungi when designing proper strategies for landscape management. Fil: Grilli, Gabriel.

Abstract: Here, we compare arbuscular mycorrhizal fungi (AMF) communities and fatty acids in soils under different no-till (NT) agricultural managements over two seasons in two consecutive years. Two NT practices with different agricultural managements were compared: crop rotation (CR) and soya bean monoculture (MC). Soils of natural grasslands (NGs) were used as a reference. Treatments were tested along a regional gradient (four geographical locations) across a 400-km transect of the Argentinean Pampas. We identified 46 morphospecies. Several morphospecies occurred abundantly at all soils; others appeared to be restricted to specific situations. At the regional scale, CR maintained the same richness levels of AMF spores, whereas MC showed less richness, when compared with the NG. Although AMF spore density was clearly affected by cropping practices in the four locations, we could observe some changes in AMF species richness, and similar diversity under agricultural and natural soils. Fatty acid concentrations (whole-cell, phospholipid and neutral lipid fatty acids) revealed differences between soil managements and showed similar patterns of variation in all locations. Spore density positively correlated with all soil lipids fractions. The results suggest that AMF spore communities and fatty acids in soils are suitable indicators of soil management involving different levels of crop rotation. Spore richness measured at a regional scale proved to be sensitive to different NT agricultural managements. Moreover, certain morphospecies could be good bioindicators for NT practices based on cropping systems on the Argentinean Pampas.

Abstract: We asked if exotic Pinus elliotti seedlings can survive and form ectomycorrhizas at higher elevations and long distances from their current range, and which ECM partners disperse to these soils. We selected three plots at four grassland sites along an altitudinal gradient (900, 1600, 2200, and 2700 m asl) established at c. 110, 3000, 6000, and 9000 m from the closest pine plantation, respectively. We combined field experiments with glasshouse assays to assess survival and ECM fungi in roots and soils. A pine plantation close to the lowest site was also selected for DNA metabarcoding of soils. Pine seedlings survived at all altitudes but not all formed mycorrhizas. They formed mycorrhizas with Suillus granulatus at 900, 1600, and 2200 m asl (i.e. up to 6000 m from the closest pine plantation), and with Rhizopogon pseudoroseolus and Thelephora terrestris at lower altitudes and distances. Twelve ECM fungal OTUs were found in grasslands and 34 were detected in the pine plantation. Although richness and abundance of ECM fungi decreased with increasing distance from the pine plantation, there was at least one non-native ECM fungal species present in each sampling site, even at 2700 masl and 9000 m distance from the closest plantation. This study provides evidence that the availability of suitable fungal symbionts might constrain but not hinder the expansion of a pine species over wide distances and altitudinal zones even in areas with no native ECM fungi.

Abstract: Aim: A growing number of studies show a discrepancy between the isotopic composition of xylem water and plant water sources. We tested the effect of arbuscular mycorrhizal fungi (AMF) on the isotopic composition of Acacia caven xylem water. As the most common plant-fungal association, AMF might explain this isotopic mismatch. Methods: Seedlings were grown with and without AMF and irrigated with the same water. After 120 days, stem and soil samples were collected and following cryogenic distillation, H and O isotopic composition of xylem and soil water, as well as irrigation water, was measured. Results: Xylem water of non-mycorrhizal seedlings was significantly depleted in 2H compared to soil water (differences up to −15.6‰). When AMF were present, the depletion was significantly higher and appeared for both H and O (differences up to −24.6‰ for δ2H and − 2.9‰ for δ18O between soil and xylem water). Conclusions: Results suggest that isotopic fractionation occurred during water uptake in this xerophytic species. To explain this, we propose an aquaporin-driven mechanism mediating water transport via transmembrane passage. Furthermore, we show for the first time, that AMF enhance the observed discrimination against heavy isotopes, probably by enforcing water passage through aquaporins. Given their ubiquity, AMF could question the fractionation-free assumption during root water uptake. Fil: Poca, María. Consejo Nacional de Investigaciones Científicas y Técnicas.

32. Latitudinal Distribution of Mycorrhizal Types in Native and Alien Trees in Montane Ecosystems from Southern South America

Abstract: Biological invasions constitute a global environmental threat that rapidly alters natural communities and ecosystem functioning. A way to understand the success of alien trees in novel ecosystems is by comparing their ecological strategies with those of natives. Plants often associate with mycorrhizal fungi in their roots to enhance nutrient acquisition. According to fungal identity, morphological structures and functioning, different types of mycorrhizas can be distinguished. Despite the phylogenetic imprints that often characterize mycorrhizal distribution among plants, it is well known that mycorrhizal types vary across environmental gradients, vegetation types and plant life forms. Then, at the global scale, the different types of mycorrhizas are not randomly distributed across biomes but rather related to environmental variables. In this chapter we examine the patterns of mycorrhizal distribution in native and alien tree species occurring in contrasting montane ecosystems across a broad latitudinal gradient in South America. We analyze whether patterns of mycorrhizal distribution in alien trees tend to converge or diverge with those in observed in natives. From the analyses we conclude that patterns of mycorrhizal distribution in alien and native trees occurring in montane ecosystems from subtropical to temperate regions, roughly follow those predicted by models of mycorrhizal distribution at global scales. This is seemingly in line with the idea of broad scale environmental filters driving predominance of convergences in the functional strategies of coexisting tree species along these mountain biomes. Nonetheless, ECM in aliens is in higher proportion compared to natives, particularly in temperate forests. Results of this chapter suggest that mycorrhizal associations have an unambiguous role in tree invasions in montane forests across different climates. However, they also reveal that the relative importance of each mycorrhizal type in each ecosystem remains to be determined.

Abstract: Several technologies have been developed with the aim of obtaining fuels from algae. In the present work, the fast pyrolysis of three different types of microalgae (Botryococcus braunii, Spirulina platensis, and Pithophora sp.) is investigated focusing on the quality and yield of the liquid product as a potential biofuel. The characterization of microalgae shows an elevated content of lipids in Botryococcus braunii, higher levels of proteins in Spirulina, and an equal number of proteins and carbohydrates in Pithophora sp. A fixed bed reactor, connected to a vacuum system, and nitrogen as inert gas flow are used in the pyrolysis experiments at 300, 400, 500, and 600 °C. At 500 °C, Botryococcus braunii produces the maximum amount of pyrolytic oil (65% yield) while Spirulina and Pithophora sp. affords the greatest amount at 600 °C, in 45% and 28% yield, respectively. Gas chromatography-mass spectrometry (GC–MS) analysis of the Botryococcus braunii-derived oils shows a high content of long-chain derivatives of alcohols, carboxylic acids, and unsaturated hydrocarbons. On the other hand, Spirulina-derived oil consists mostly of nitrogenated compounds while oil from Pithophora sp. is composed of oxygenated and/or nitrogenated products, depending on the reaction temperature. The measured higher heating value (HHV) of Botryococcus braunii-derived oil produced at 500 °C is 45 MJ/kg and this bio-oil could be used as a feedstock for fuel production after chemical upgrading to decrease the oxygen content (6.59 wt%).

Abstract: We aimed to evaluate if exotic ectomycorrhizal fungi from exotic pine plantations disperse through non-native, but also native, mammals in a mountain ecosystem devoid of native ECM plants. Among four non-native and three native mammal species, feces of non-native wild boar (Sus scrofa) and brown hare (Lepus europaeus), and native pampa fox (Lycalopex gymnocercus) were selected to inoculate seedlings of Pinus elliottii. These feces came from two transects in an elevation gradient (1350–2250 m asl) and different distances from a pine plantation (100–6000 m). We show that feces of wild boar, brown hare (non-native), and pampa fox (native) were effective as inoculum for establishing ectomycorrhizal pine seedlings. Through molecular analyses, we determined that two species are mostly consumed and successfully form ectomycorrhizas with pine roots: Suillus granulatus and Rhizopogon pseudoroseolus. We provide novel evidence for the long-distance dispersal of exotic ectomycorrhizal fungi by non-native and native animal vectors.

Abstract: Plant uptake of dissolved organic nitrogen (DON) has been proposed to explain inconsistency in the ecosystem N balance of semi-arid systems. Nevertheless, direct evidence for an ecologically important role of DON in plant nutrition in these systems remains elusive under field conditions. Here, natural abundance 15N signatures of NO3−, NH4+, DON and whole plants from a semi-arid model forest were analyzed to provide robust estimates of plant N source partitioning and relative N cycling rates under in-situ conditions. Concurrently, architectural and symbiotic root traits were determined to assess their relationship to plant N acquisition strategies. Bayesian isotope mixing models indicated an insignificant contribution of DON to ecosystem plant N nutrition. Nitrate was the dominant plant N source in this ecosystem, while the contribution of NH4+ to plant nutrition varied between herbaceous (26%) and woody plants (8%). The low C:N ratio of the dissolved organic matter pool - ranging from 12.7 to 4.9 within the soil profile ? indicated microbial C-limitation in this ecosystem. Dissolved organic N was significantly enriched in 15N relative to NH4+ and NO3−, corroborating the importance of dissolved organic matter recycling as a cost-effective pathway that simultaneously supplies C and nutrients for microbial metabolism. Plants exclusively depend on inorganic N forms made available through microbial N mineralization and free-living atmospheric N2 fixation, followed by autotrophic nitrification. Fil: Huygens, D..

Nuestra hipótesis de trabajo es que la comunidad fúngica se modifica en concordancia con las situaciones del bosque: alta degradación, bosque natural maduro y bosque restaurado. Se compararon variables fúngicas (riqueza, abundancia y equitatividad de macromicetes) de un área nativa, de un área degradada y reforestada y de un área degradada sin reforestación. Para ello se establecieron 15 parcelas de 5x5 m y se muestrearon cinco por estación. Se recolectaron las fructificaciones de macromicetes, y luego se las clasificó en grupos morfo-taxonómicos. Se hicieron análisis de componentes principales y de correlación entre las variables fúngicas y la estructura vegetal, y análisis de correlación entre las variables fúngicas y las variables químicas del suelo. La riqueza, la abundancia y la equitatividad fueron significativamente mayores en el área nativa, intermedias en el área reforestada y menores en el área degradada. Las parcelas del área nativa se caracterizaron por una alta cobertura de árboles maduros, las del área reforestada por graminoides y árboles jóvenes y las del área degradada por herbáceas latifoliadas. Las tres variables fúngicas fueron máximas a mayor cobertura arbórea y correlacionaron positivamente con el fósforo y pH del suelo. Los resultados muestran que 12 años después de que un área degradada fuera reforestada con P. australis, la diversidad fúngica es mayor que la de un área degradada, pero está lejos de alcanzar los niveles del área nativa. Se postula que los hongos serían bioindicadores sensibles a la degradación y la restauración de los bosques. Polylepis australis forest had been significantly disturbed and afforestation is an alternative to restore these ecosystems. The aim of this study is to evaluate the restoration of the fungal community in P. australis afforestation. Our hypothesis is that the fungal community varies between forest situations: high degraded, mature forest, and restored forest. Fungal variables (richness, abundance and evenness of macromicetes) were compared between a native area, an afforestation and a degraded land. To this end, 15 plots of 5x5 m were established and five of them were sampled in each season. Macromicetes fruiting bodies were collected and classified into different morpho-taxonomical groups. Principal Components Analyses and correlation analyses between the fungal variables and the plot’s structure were performed as well as correlation analysis between the fungal variables and soil chemical variables. Richness, abundance and evenness were significantly higher in the native area, intermediate in the afforestation and lower in the degraded land. The native area’s plots showed high tree cover, the afforestation´s plots high graminoid and young trees cover, and the degraded land’s plots high forbs cover. Values of fungal variables were higher at higher tree cover and were positively correlated with soil phosphorus content and pH. The results show that, after 12 years of afforestation with P. australis, the fungal diversity in that ecosystem is higher than the observed in reference degraded land but is far from the observed in a native area. It can be hypothesized that fungi are sensitive bioindicators of forest degradation and restoration.

Abstract: It is generally assumed that recruitment and expansion of alien species along elevation gradients are constrained by climate. But, if plants are not fully constrained by climate, their expansion could be facilitated or hindered by other factors such as biotic interactions. Here, we assessed the composition of arbuscular mycorrhizal fungi (AMF) in soils along an elevation gradient (i.e. 900 m, 1600 m, 2200 m and 2700 m a.s.l.) through a fungal DNA meta-barcoding approach. In addition, we studied in the greenhouse the effects of AMF on growth and phosphorous (P) nutrition of seedlings of the alien trees Gleditsia triacanthos, Ligustrum lucidum and Pyracantha angustifolia cultivated in soils from those elevations, spanning the elevation at which they already form monospecific stands (below 1450 m a.s.l.) and higher elevations, above their current range of distribution in montane ecosystems of Central Argentina. For comparison, we also included in the experiment the dominant native tree Lithraea molleoides that historically occurs below 1300 m a.s.l. Arbuscular mycorrhizal fungal community composition showed strong community turnover with increasing elevation. The effects of these AMF communities on plant growth and nutrition differed among native and alien trees. While P nutrition in alien species? seedlings was generally enhanced by AMF along the whole gradient, the native species benefited only from AMF that occur in soils from the elevation corresponding to its current altitudinal range of distribution. These results suggest that AMF might foster upper range expansion of these invasive trees over non-invaded higher elevations. Fil: Urcelay, Roberto Carlos.

Abstract: Summary Land-use changes and forest fragmentation have strong impact on biodiversity. However, little is known about the influence of new landscape configurations on arbuscular mycorrhizal fungal (AMF) community composition. We used 454 pyrosequencing to assess AMF diversity in plant roots from a fragmented forest. We detected 59 virtual taxa (VT; phylogenetically defined operational taxonomic units) of AMF – including 10 new VT – in the roots of Euphorbia acerensis. AMF communities were mainly composed of members of family Glomeraceae and were similar throughout the fragmented landscape, despite variation in forest fragment size (i.e. small, medium and large) and isolation (i.e. varying pairwise distances). AMF communities in forest fragments were phylogenetically clustered compared with the global, but not regional and local AMF taxon pools. This indicates that non-random community assembly processes possibly related to dispersal limitation at a large scale, rather than habitat filtering or biotic interactions, may be important in structuring the AMF communities. In this system, forest fragmentation did not appear to influence AMF community composition in the roots of the ruderal plant. Whether this is true for AMF communities in soil and the roots of other

Abstract: Anthropogenic activities have increased disturbances and alien woody invasion in mountain ecosystems worldwide. Whether disturbances promote or counteract upward movement of woody aliens is poorly understood. We assessed if the most successful woody invader of low mountains of central Argentina (Gleditsia triacanthos) might expand its elevational distribution in response to the principal disturbances of these ecosystems (fire and livestock browsing) across increasing climatic severity. We assessed seedling emergence, growth and mycorrhizal colonization on sown plots distributed in burned and unburned sites, with and without browsing at the lower and upper elevation belts (i.e. 1000 and 2400 m a.s.l.). Additionally, several abiotic variables were measured to relate their influence on the seedling establishment. Disturbances reduced seedling emergence at both elevations. Burned conditions increased seedling growth and arbuscular colonization only in the lower belt. Seedling success (total seedling biomass per plot) was not modified by disturbances at the upper elevation, but was reduced by browsing and enhanced by fire in the lower elevation. The overall reduction in seedling emergence and growth in the upper elevation despite the higher soil nutrient content places climate as the strongest regulator of G. triacanthos seedling establishment. Accordingly, climate rather than disturbances would be the main limiting factor of upward expansion of this woody alien. Our findings differ from general patterns described for mountain invasion by herbaceous species, highlighting that mountain invasibility is highly growth-form dependent, and that upper range expansion by woody aliens interacting with multiple disturbances should be assessed worldwide.

Abstract: Based on molecular evidence and morphological analyses, a new species in the genus Trametopsis is revealed. Trametopsis aborigena sp. nov. is proposed and described from South America. Molecular phylogenetic analyses of ITS and LSU rDNA sequences suggest that Trametopsis cervina seems to encompass more than one species and confirm previous results showing that Antrodiella brasiliensis groups with Trametopsis. The morphological analyses of type specimens of A. brasiliensis and A. luteocontexta revealed a shared morphological pattern with Trametopsis and their combinations in Trametopsis are proposed. The circumscription of Trametopsis is discussed since all the studied specimens revealed a previously overlooked arrangement of characters, i.e., cylindrical and slightly curved to allantoid basidiospores and a metachromatic hyphal system monomitic in the context and dimitic in the tubes.

Abstract: Forest fragmentation and biological invasions modify plant–mycorrhizal fungal interactions, but how these variations affect native and invasive plant vegetative and reproductive growth in a fragmented forest remain unknown. To test the effects of soil fungi from different forest fragment sizes on native and invasive plants, we conducted a greenhouse factorial experiment combining soil source (i.e., small and large forest fragments) and fungicide application (with and without fungicide) on two ruderal congeneric Euphorbia (E. acerensis and E. dentata, native and invasive, respectively). Soil fungi from small forest fragments promoted lower rates of mycorrhizal colonization than soil from large forest fragments in both plant species. In general, the source of soil fungi had no effect on vegetative and reproductive growth of both plant species. Fungicide application positively affected plant height and dry mass of the native host, while the fungicide application negatively affected height and neutrally affected growth of the invasive plant species. Reproductive traits were in general positively affected by fungicide application, although in some cases, they were dependent on soil source. Forest fragmentation might promote changes in soil conditions that negatively affect mycorrhizal colonization at levels without functional consequences for plant growth. However, landscape modifications that contribute to a more severe reduction in Arbuscular Mycorrhizal (AM) fungal colonization might certainly have important consequences on native and invasive plant growth.

Abstract: It is well known that arbuscular mycorrhizal fungi (AMF) effects on plant growth largely depend on fungus identity. The objective of this study was to test whether three individual AMF isolates and their mixture mitigate drought stress (DS) differentially in soybean (Glycine max) genotype, predicting that under DS, the mixture of the AMF isolates would provide greater benefits to soybean plants than individual ones. In a greenhouse experiment, a drought-susceptible soybean genotype was inoculated with Septoglomus constrictum, Glomus sp., and Glomus aggregatum, known to be among the most abundant in agricultural and natural soils from central Argentina, and their mixture (Mx). Whereas under wellwatered (WW) conditions, individual isolates and Mx treatment were similarly infective; under DS conditions, the Mx treatment showed lower rates of root colonization. Between WW and DS conditions, biomass was decreased in all treatments, although this effect was more marked in non-AM plants. Moreover, AMF strains improved water content and P and N concentrations. Under DS, the Mx treatment was unable to exceed the highest contents that were recorded by AMF isolates. However, under WW conditions, the Mx treatment showed a higher N content than individual isolates. Under both watering conditions, AM plants reduced oxidative damage evaluated as malondiadehyde and chlorophyll content and keep constant osmotic metabolites such as soluble sugars and proline content, without significant differences between AMF isolates and the Mx treatment. These results show that AMF play an important role in mitigating drought impacts on soybean, but that mixtures of AMF isolates did not perform as well as the best single strain inoculum, excluding complementarity effects and suggesting selection effect of AMF on DS alleviation in soybean.

Abstract: Pérez-Harguindeguy et al., Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels and influence ecosystem properties. Variation in plant functional traits, and trait syndromes, has proven useful for tackling many important ecological questions at a range of scales, giving rise to a demand for standardised ways to measure ecologically meaningful plant traits. This line of research has been among the most fruitful avenues for understanding ecological and evolutionary patterns and processes. It also has the potential both to build a predictive set of local, regional and global relationships between plants and environment and to quantify a wide range of natural and human-driven processes, including changes in biodiversity, the impacts of species invasions, alterations in biogeochemical processes and vegetation-atmosphere interactions. The importance of these topics dictates the urgent need for more and better data, and increases the value of standardised protocols for quantifying trait variation of different species, in particular for traits with power to predict plant-and ecosystem-level processes, and for traits that can be measured relatively easily. Updated and expanded from the widely used previous version, this handbook retains the focus on clearly presented, widely applicable, step-by-step recipes, with a minimum of text on theory, and not only includes updated methods for the traits previously covered, but also introduces many new protocols for further traits. This new handbook has a better balance between whole-plant traits, leaf traits, root and stem traits and regenerative traits, and puts particular emphasis on traits important for predicting species' effects on key ecosystem properties. We hope this new handbook becomes a standard companion in local and global efforts to learn about the responses and impacts of different plant species with respect to environmental changes in the present, past and future. © CSIRO 2013., This contribution was funded, in part, by the Inter-American Institute for Global Change Research (IAI) CRN 2015 and SGP-CRA2015, which were supported by US National Science Foundation Grants GEO-0452325 and GEO-1138881 The work was also funded by FONCyT (PICT 20441 and 365), CONICET (PIP 2006-2011 11220080101532), SECYT-Universidad Nacional de Córdoba – Argentina, and the US NSF (DEB-0620652).

Abstract: It has been predicted that land use change will pose the main threat to biodiversity worldwide (Sala et al. 2000). A recent meta-analysis shows that, at local scale, conversion and degradation of habitats promote on average a global decline of 8.1 % of species richness and 10.1 % of abundance (Newbold et al. 2015). These human-mediated changes in biodiversity strongly affect ecosystem stability (Hautier et al. 2015). Given the importance of biodiversity on ecosystem functions and services, studies on the effects of land use on species assemblages are highly relevant in current global context.

Abstract: We performed a comprehensive comparative study of functional traits in coexisting alien and native woody species in order to examine the strategies related to resource use and dispersion underlying alien success in mountain Chaco woodlands of central Argentina. Our approach integrated seemingly contrasting pieces of evidence in the region. We specifically assessed whether (i) the 'functional acquisitive trend' previously observed along a broad environmental gradient accounts for woody alien naturalization when considering a single mesic ecosystem; or (ii) more than one trait syndrome is important among alien species, which would be more in line with the context-dependent nature of biological invasions at a local scale. Fifteen vegetative and regenerative traits were measured on the most common 14 native and 11 alien woody species.We compared the attributes of (i) native and alien species and (ii) between native species and two contrasting groups of alien species identified in the previous analysis. The overall trait comparison (i) showed that, in terms of vegetative attributes, woody alien species tend to be on average more acquisitive than native species. However, (ii) two contrasting syndromes were revealed among alien species: a group of seven deciduous species with acquisitive attributes; and a group of four evergreen species showing markedly more conservative attributes than the first group. The functional attributes of 'conservative aliens' completely overlapped with the range observed for native species, except for an exclusive dispersal phenology and a stronger tendency to clonal spread. Acquisitive aliens, in turn, proved to be beyond the range of attributes of native species, at the acquisitive extreme, as they did in previous comparisons. Despite their importance, general trends in plant functional attributes across regions and ecosystems can sometimes obscure trends at more local scales that are nevertheless important for the understanding and management of particular systems. Our study concurs with previous general trends when looking at the overall comparison between native and alien species, but unveils contrasting functional strategies among alien species when examining their attributes more closely, even within the same ecosystem.

Abstract: In the past few decades, it has been widely accepted that forest loss due to human actions alter the interactions between organisms. We studied the relationship between forest fragment size and arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) colonization, and the AMF spore communities in the rhizosphere of two congeneric Euphorbia species (native and exotic/invasive). We hypothesized that these fungal variables will differ with fragment size and species status, and predicted that (a) AMF and DSE colonization together with AMF spore abundance and diversity would be positively related to forest fragment size; (b) these relationships will differ between the exotic and the native species; and (c) there will be a negative relationship between forest fragment size and the availability of soil nutrients (NH4 +, NO3-, and phosphorus). This study was performed in the eight randomly selected forest fragments (0.86-1000 ha), immersed in an agricultural matrix from the Chaquean region in central Argentina. AMF root colonization in the native and exotic species was similar, and was positively related with forest fragment size. Likewise, AMF spore diversity and spore abundance were higher in the larger fragments. While DSE root colonization in the native host was positively related with forest fragment size, DSE colonization in the exotic host showed no relationship. Soil nutrients contents were negatively related with forest fragment size. In addition, NH4 and NO3 were negatively correlated with AMF spores abundance and root colonization and with DSE colonization in the native species. The results observed in this study show how habitat fragmentation might affect the interaction between key soil components, such as rhizospheric plant-fungal symbiosis and nutrient availability. These environmental changes may have important consequences on plant community composition and nutrient dynamics in this fragmented landscape. Fil: Grilli, Gabriel.
