Decline in endangered species as an indication of anthropic pressures: the case of European mink Mustela Iutreola western population

摘要

Populations of threatened species, especially predators at the top of the food chain, may be affected by anthropic pressures. The endangered western population of European mink Mustela Iutreola has shown a large decline Over 50/100 of its nature range. M.Iutreola disappeared from Northwestern France between 1984 and 1997, and the de- Cline was associated with an increase in mustelid trapping, Changes in wastercourse quality, and habitat modifications due To agricultural practices. The pattern of decline showed a frag- Mentation restricting the minks into very small areas. Trapping Was the first known cause of mortality.
