The Cerrado biome spans 2M km2 and is chronically underprotected. Just 30 species contribute half of tree stems. New analysis supported by ForestPlots shows why the combination of climate change and habitat loss threatens them, and the future of the Cerrado. onlinelibrary.wiley.com/doi/10.1111/...

Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (g.....

UMR AMAP - botAnique et Modélisation de l'Architecture des Plantes et des végétations When plants die, neighbours escape competition. Living conspecifics could disproportionately benefit because they are freed from negative intraspecific processes; however, if the negative effects of past neighbours persist, other species may be advantaged and diversity maintained through ‘legacy effects’ of dead trees. Using large mapped forest plots, we examine whether antecedent communities shape forest dynamics and how long dead-tree legacies persist. We find that per-capita interaction strength of dead neighbours exceeds that of living trees, and that density-dependent effects from dead trees can persist for up to 10 years after death. Over 75% of species show negative responses to dead-tree neighbours, compared with 67% to living neighbours. Preliminary evidence suggests consistent legacy effects across tropical and temperate forests, with no clear mediating gradients. The drivers of tree legacy effects remain a mystery.

UMR AMAP - botAnique et Modélisation de l'Architecture des Plantes et des végétations Conformal prediction methods are statistical tools designed to quantify uncertainty and generate predictive sets with guaranteed coverage probabilities. The two works I will present, introduce refinements to these methods for classification tasks, one specifically tailored for long-tailed classification and, the other one, for scenarios where multiple observations (multi-inputs) of a single instance are available at prediction time. Our approach is particularly motivated by applications in citizen science such as Pl@ntnet, where the distribution of species has this behavior and where multiple images of the same plant or animal are captured by individuals at test time. These works have been done in collaboration with Joseph Salmon (UM), Tiffany Ding (UC Berkeley) and Mohamed Hebiri (Université Gustave Eiffel).

Sciences des données et IA au service des transitions : INRAE et Inria élargissent leur partenariat stratégique COMMUNIQUÉ DE PRESSE - Ce 26 février 2026, Philippe Mauguin, président-directeur général d’INRAE, et Bruno Sportisse, président-directeur général d’Inria, ont signé le renouvellement de l’accord-cadre de partenariat entre les deux instituts pour la période 2026-2030. Dans un contexte marqué par la nécessité d’intensifier les transitions agricoles, alimentaires et environnementales, et par l’essor rapide de la science des données et de l’intelligence artificielle (IA), INRAE et Inria réaffirment leur ambition commune : conjuguer excellence scientifique et innovation numérique pour répondre aux grands défis sociétaux.
