How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany
Wildlife Biology, EarlyView.Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Ecologie des systèmes alimentaires : Définition
, 2022 L’écologie des systèmes alimentaires (SA) désigne une approche englobant l’agroécologie et la manière de se nourrir, de façon à prendre en compte les interdépendances entre l’environnement, l’alimentation et les filières. Fondée sur des approches holistiques, de type « one-health », cette approche interdisciplinaire en cours de construction permet d ...

Wildlife Monographs, EarlyView.Abstract Woodland caribou (Rangifer tarandus) are one of the most iconic wildlife species in Canada. These large ungulates depend on undisturbed, interconnected assemblages of mature and old‐growth conifer forests for survival, and exhibit life‐history traits typical of K‐selected species (i.e., low reproductive rates, long generation times, and slow ...

Journal of Animal Ecology, EarlyView.We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Quels programmes d’amélioration génétique des animaux pour des systèmes d’élevage agro-écologiques ?
INRAE Productions Animales, 2017 L’agro-écologie utilise les processus naturels et les ressources locales plutôt que des intrants chimiques pour assurer la production tout en limitant l’impact environnemental de l’agriculture.

Ranking threats to biodiversity and why it doesn’t matter
Nature Communications, 2022 Several rankings of the relative importance of global threats to biodiversity have been proposed. This Comment argues that relative rankings of biodiversity threats have little application for conservation and might even mislead policymaking.
