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. The reasons for this overall conservation success include protective legislation, supportive public opinion, and a variety of practices making coexistence between large carnivores and people possible. The European situation reveals that large carnivores and people can share the same landscape.
In the last two centuries, persecution and deforestation caused grey wolf Canis lupus populations in Europe to decline. Recently, their numbers started to recover although most populations still remain isolated from one another. This study presents the first documented evidence of the successful reconnection of the Dinaric-Balkan and the Alpine wolf populations via long distance dispersal and subsequent reproduction. A young male wolf radiocollared in the Dinaric Mountains in July 2011 travelled through Slovenia and Austria to the Italian Alps, where he settled in March 2012. During the 98 days of dispersal period the wolf has travelled a cumulative line distance of 1176 km crossing multiple anthropogenic and natural barriers, and successfully hunting wild prey until he settled 233 km straight line distance from its natal territory. Camera trapping, snow tracking and genetic evidence in the new territory confirmed pairing with a female wolf from the neighboring Alpine population. In the following year the pair has produced a first documented "mixed" litter between wolves from the Dinaric-Balkan and the Alpine wolf populations.This case study demonstrates the potential for the future merging of European wolf populations even in human-dominated landscapes and highlights the importance of transboundary cooperation in wolf research and management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
