Les Cesabinars, qui se déroulent en anglais sur Zoom, ont une durée d’environ une heure : 40 minutes sont consacrées à la présentation, suivies de 20 minutes d’échanges pour poser vos questions et approfondir les sujets abordés.
Vous trouverez ici toutes les informations relatives au prochain Cesabinar ainsi que les informations et enregistrements relatifs aux sessions précédentes.
Au plaisir de vous retrouver sur Zoom !
PROCHAIN CESABINAR
Nous avons le plaisir d’annoncer le troisième Cesabinar de l’année 2026, qui aura lieu le jeudi 23 avril à 15h (heure de Paris). Jérôme Mathieu (Sorbonne Université) & Miguel Cooper (Universidade de São Paulo) nous parlerons du travail du projet FaunaServices :
Relations entre la biodiversité de la macrofaune du sol et la fourniture de services écosystémiques dans les néotropiques d’Amérique du Sud.
Meeting ID: 821 3670 7026
FaunaServices: Towards Quantifying Ecosystem Services Delivered by Soil Macrofauna in the Neotropics
Neotropical forests are widely recognized for their crucial role in climate regulation, particularly through tree-mediated water cycles. However, these ecosystems also harbor an exceptional diversity and abundance of soil organisms, whose contributions to ecosystem services have largely been overlooked. Yet, these organisms are highly vulnerable to land-use change and are rapidly declining with deforestation.
Quantifying their contribution to ecosystem functioning is therefore essential to fully understand the broader consequences of deforestation beyond vegetation loss.
In this project, we aimed to quantify key ecosystem services provided by soil macrofauna. To do so, we developed four harmonized databases: (i) a standardized dataset on the abundance of 40 soil macrofauna taxa (3k sites), (ii) a database on earthworm species occurrence and abundance (1.5k sites) , (iii) a dataset on soil profiles and associated ecosystem services (6k sites), and (iv) a database documenting the impacts of ecosystem engineers on soil processes (>1k records).
This seminar will present the main outcomes of the FaunaServices project, highlight the challenges encountered, and discuss how this initiative has laid the foundation for a long-term research network dedicated to understanding soil macrofauna-driven ecosystem services across South America.
