We are very pleased to announce our next online CESABINAR, which will take place on Thurs Mar 26th, at 3:00pm, Paris time). Mélanie Roy (Toulouse University, France / IRL IFAECI, Buenos Aires, Argentina), Caroline Dracxler (São Paulo University & Federal University of Rio de Janeiro, Brazil) et Paulo R. Guimaraes Jr. (São Paulo University, Brazil) will present the work of the NEFINEO group: Network of Interactions in the Neotropics – a field guide to mushroom networks.

Network of interactions in the neotropics – A field guide to mushroom networks
Our project aimed at exploring the ecology of interactions involving ectomycorrhizal (ECM) fungi – that form symbioses with tree roots – in the Neotropics. Ectomycorrhizal interactions involve fungi belonging to up to 86 lineages and are often dominant in temperate and boreal forest soils – but show a scattered distribution and a lower diversity in the Neotropics as compared with other regions.
Our CESAB group joined fungal and network ecologists from Brazil and France, but also Mexico, Colombia, Argentina, and United Kingdom. We aimed at gathering data from specimen and symbioses observations, specimens and root tips sequencing, and soil eDNA to explore new hypotheses explaining the peculiar ECM diversity pattern in the Neotropics. We evaluated (1) how far the evolutionary history of Neotropical ECM differed from other regions and among lineages, (2) if environmental conditions or biogeographic history shape the present distribution of ECM in soils and (3) how these rare ECM symbioses could contribute to ecosystem stability through indirect interactions.
For this CESABINAR, we will present our advances on these three axes, the challenges of gathering eDNA data from diverse projects and barcodes, and the perspectives for network ecology and conservation biology.

______________________
The aim of these CESABINARS is to present the main results of the working groups once they finish a CESAB cycle. They last about 1 hour: 40 minutes of presentation and 20 minutes of questions, perhaps a bit more. The CESABINARs are open to the whole scientific community, to the participants of the CESAB groups and to the FRB network. They are in English, so don’t hesitate to promote them in your networks.
In case you miss it, this session (and all the other ones whenever possible) will be recorded and shared on the FRB’s Youtube channel.
