Quantifier l'impact d'une certaine quantité d'émissions de gaz à effet de serre sur les ours polaires n'avait pour le moment jamais été fait.

Wildlife return in Europe is seen by many as a great conservation success, but it brings some new challenges too. For centuries, the wolf, the bear, the lynx and wolverine, were chased and expelled from their natural habitats – and went almost extinct in many European places. However, the current land use in Europe, habitat improvement and increase of prey species - backed by the legal protection large carnivores have in some countries - brought a new opportunity for them to come back, raising potential conflicts between farmers and livestock producers, hunters, local authorities, protected areas, and NGOs.

The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using a data set on the past and current status of brown bears (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolves (Canis lupus), and wolverines (Gulo gulo) in European countries, we show that roughly one-third of mainland Europe hosts at least one large carnivore species, with stable or increasing abundance in most cases in 21st-century records.

Understanding the processes related to wildlife recoveries is not only essential in solving human - wildlife conflicts, but also for identifying priority conservation areas and in turn, for effective conservation planning. We used data from a large citizen science program to study the spatial processes related to the demographic and genetic recovery of brown bears in Greece and to identify new areas for their conservation. This was achieved by visually comparing our data with an estimation of the past distribution of brown bears in Greece and by using a Point Process Model to model habitat suitability, and then comparing our results with the current distribution of brown bear records and with that of protected areas.
