摘要: Abstract In northern Belarus, we have documented a decline in the local stoat Mustela erminea population following naturalisation of American mink vison. The most likely cause is reduction density and distribution main prey stoats, riparian voles (the water vole Arvicola terrestris root Microtus oeconomus), due to excessive predation by mink. Since has declined, number weasels nivalis marshlands increased their mean body mass increased, correlated with higher weights rodents available for marshland compared forest habitats.
