Plan Maestro Humedales

El Plan Maestro Humedales forma parte del grupo de iniciativas regionales que la gestión provincial ha priorizado en materia de planificación integral para la provincia, y tiene por objetivo apor tar al gobierno un instrumento para la gestión integral del territorio que colabore en el fortalecimiento de su accionar en relación con la conservación y gestión sustentables del Humedal Chaco. Este trabajo fue desarrollado en el marco de un convenio entre el gobierno provincial con el Consejo Federal de Inversiones (CFI) y Viator Proyectos SA, con la coordinación general de la Subsecretaría de Planificación y Proyectos del Ministerio de Infraestructura y Servicios Público

Global patterns in endemicity and vulnerability of soil fungi

Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns and conservation needs of fungi have been little explored. Here, we examined endemicity patterns, global change vulnerability and conservation priority areas for functional groups of soil fungi based on six global surveys using a high-resolution, long-read metabarcoding approach. We found that the endemicity of all fungi and most functional groups peaks in tropical habitats, including Amazonia, Yucatan, West-Central Africa, Sri Lanka, and New Caledonia, with a negligible island effect compared with plants and animals. We also found that fungi are predominantly vulnerable to drought, heat and land-cover change, particularly in dry tropical regions with high human population density. Fungal conservation areas of highest priority include herbaceous wetlands, tropical forests, and woodlands. We stress that more attention should be focused on the conservation of fungi, especially root symbiotic arbuscular mycorrhizal and ectomycorrhizal fungi in tropical regions as well as unicellular early-diverging groups and macrofungi in general. Given the low overlap between the endemicity of fungi and macroorganisms, but high conservation needs in both groups, detailed analyses on distribution and conservation requirements are warranted for other microorganisms and soil organisms

Connecting the multiple dimensions of global soil fungal diversity

15 páginas.- 5 figuras.- 99 referenciasHow the multiple facets of soil fungal diversity vary worldwide remains virtually unknown, hindering the management of this essential species-rich group. By sequencing high-resolution DNA markers in over 4000 topsoil samples from natural and human-altered ecosystems across all continents, we illustrate the distributions and drivers of different levels of taxonomic and phylogenetic diversity of fungi and their ecological groups. We show the impact of precipitation and temperature interactions on local fungal species richness (alpha diversity) across different climates. Our findings reveal how temperature drives fungal compositional turnover (beta diversity) and phylogenetic diversity, linking them with regional species richness (gamma diversity). We integrate fungi into the principles of global biodiversity distribution and present detailed maps for biodiversity conservation and modeling of global ecological processes.This work was supported by the Estonian Science Foundation: PRG632 (to L.T.), Estonian Research Council: PRG1615 (to R.D.), Estonian Research Council: PRG1170 (to U.K. and Ka.Po.), Estonian Science Foundation: MOBTP198 (to St.An.), Novo Nordisk Fonden: NNF20OC0059948 (to L.T.), Norway-Baltic financial mechanism: EMP442 (to L.T., K.-A.B., and M.T.), King Saud University: DFSP-2020-2 (to L.T.), King Saud University: Highly Cited Program (to L.T.), European Regional Development Fund: Centre of Excellence EcolChange TK131 (to M.O., M.Z., Ü.M., U.K., and M.E.), Estonian Research Council: PRG1789 (to M.O. and I.H.), British Ecological Society: LRB17\1019 (MUSGONET) (to M.D.-B.), Spanish Ministry of Science and Innovation: PID2020-115813RA-I00 (to M.D.-B.), Spanish Ministry of Science and Innovation: SOIL4GROWTH (to M.D.-B.), Marie Sklodowska-Curie: 702057 (CLIMIFUN) (to M.D.- B.), European Research Council (ERC): grant 647038 [BIODESERT] (to F.T.M.), Generalitat Valenciana: CIDEGENT/2018/041 (to F.T.M.), Spanish Ministry of Science and Innovation: EUR2022-134048 (to F.T.M.), Estonian Research Council: PRG1065 (to M.M. and M.Z.), Swedish Research Council Formas: 2020-00807 (to Mo.Ba.), Swedish Research Council: 2019-05191 (to Al.

The Global Soil Mycobiome consortium dataset for boosting fungal diversity research

Fungi are highly important biotic components of terrestrial ecosystems, but we still have a very limited understanding about their diversity and distribution. This data article releases a global soil fungal dataset of the Global Soil Mycobiome consortium (GSMc) to boost further research in fungal diversity, biogeography and macroecology. The dataset comprises 722,682 fungal operational taxonomic units (OTUs) derived from PacBio sequencing of full-length ITS and 18S-V9 variable regions from 3200 plots in 108 countries on all continents. The plots are supplied with geographical and edaphic metadata. The OTUs are taxonomically and functionally assigned to guilds and other functional groups. The entire dataset has been corrected by excluding chimeras, index-switch artefacts and potential contamination. The dataset is more inclusive in terms of geographical breadth and phylogenetic diversity of fungi than previously published data. The GSMc dataset is available over the PlutoF repository
