Winter selection of habitats within intertidal foraging areas by mink (Mustela vison)

摘要: Patterns of habitat selection by American mink Mustela vison within foraging areas located on the shore, were studied in a coastal environment Scotland from November to March 1983/84, 1984/85 and 1994/95. The abundance prey intertidal zone was modelled relation abiotic environmental characteristics. Four factors found be important predictors abundance: position tidal zone, size rockpools, nature substratum presence fresh water streams. model used predict different shore. We then investigated whether choosing with higher at levels within, as opposed between, core (areas relatively high density fixes, encompassing usually one or more dens). Only when low mid-tide behave selectively. They showed no significant preference for rich tide between areas. Mink also avoid streams prefer zone. findings are discussed competition otter Lutra lutra.
