L'organisation Environmental Working Group a publié une synthèse, sous forme de carte, des espèces dont on connaît une exposition aux polluants éternels. Ces produits chimiques sont très persistants dans la nature... et dangereux. Les PFAS (substances per- et polyfluoroalkylées) ont une durée de vie si longue qu'on

Visualizing how migratory animals connect continents, countries, sites and habitats is the result of an international scientific effort under the aegis of the CMS, in developing the first atlas of bird migration across three continents. CMS, an environmental UN treaty, will launch the Eurasian-African Bird Migration Atlas today at the Museum of Migration on the Italian island of Ventotene, as the first part of a broader initiative to develop a global atlas of animal migration.

La Journée mondiale des oiseaux migrateurs est organisée par un partenariat de collaboration entre deux traités des Nations Unies - la Convention sur la conservation des espèces migratrices appartenant à la faune sauvage ( CMS ) et l'Accord sur les oiseaux d'eau migrateurs d'Afrique-Eurasie ( AEWA ).

Le projet FAUNAPYR est un projet européen (POCTEFA) qui contribue à la protection des écosystèmes transfrontaliers à travers l’amélioration des connaissances de la répartition des espèces de la faune pyrénéenne.

L’objectif de ce projet est de mutualiser, sur un portail unique, l’ensemble des données de faune pyrénéenne.

Lancé en novembre 2019, le projet de recherche européen Alptrees s'inscrit dans le contexte de l'adaptation de l'espace alpin au changement climatique. Il regroupe 14 partenaires de cinq pays de l'arc alpin et vise à étudier les caractéristique

Freshwater fish have been widely introduced worldwide, and freshwater ecosystems are among the most affected by biological invasions. Consequently, freshwater fish invasions are one of the most documented invasions among animal taxa, with much information available about invasive species, their characteristics, invaded regions, invasion pathways, impacts, and management. While existing reviews address specific aspects of freshwater fish invasions, there is still a gaping lack of comprehensive assessments of freshwater fish invasions that simultaneously address pivotal and connected elements of the invasion process. Here, we provide a holistic review, together with quantitative assessments, divided into four major parts: (1) introduction pathways; (2) characteristics of non-native species and invaded ecosystems to explain successful invasion processes; (3) invasion impacts and their mechanisms; and (4) management.

The ongoing recovery of terrestrial large carnivores in North America and Europe is accompanied by intense controversy. On the one hand, reestablishment of large carnivores entails a recovery of their most important ecological role, predation. On the other hand, societies are struggling to relearn how to live with apex predators that kill livestock, compete for game species, and occasionally injure or kill people. Those responsible for managing these species and mitigating conflict often lack fundamental information due to a long-standing challenge in ecology: How do we draw robust population-level inferences for elusive animals spread over immense areas? Here we showcase the application of an effective tool for spatially explicit tracking and forecasting of wildlife population dynamics at scales that are relevant to management and conservation.
