The American mink
was brought to Scotland for fur-farming and has been living wild for 50 years.
We detected American beaver (Castor canadensis), American mink
, coyote, muskrat (Ondatra zibethicus), northern raccoon, red fox, Virginia opossum (Didelphis virginiana), weasel (Mustela spp.), white-tailed deer (Odocoileus virginiana), river otter, and a variety of birds and small mammals (Table 1).
Morphometric traits of the heart in standard and mutational colour variants of American mink
The Mazurian Lakeland, NE Poland, is an area where the distribution of water voles is affected by the presence of the invasive American mink
because the probability of water vole occurrence is significantly lower at sites inhabited by mink (Brzezinski et al.
Water voles have seen numbers plummet across the country in the past few decades in the face of loss of suitable habitat and because they are preyed on by invasive American mink
, which escaped or were set free from fur farms.
The rodents had become extinct in the area in the 1990s through loss of habitat, watercourse pollution and the spread of the non-native American mink
was brought over to Britain by fur farm operators.
However, it was the introduction of the North American mink
for fur farming that had a catastrophic effect on their numbers.
But habitat loss, development, water pollution and predation by invasive American mink
introduced into the UK for fur farming led to massive declines.
The nucleotide sequence, variation and gene-structure of the American mink
(Neovison vison) growth hormone gene was analyzed.
in Patagonia: an historical and socio-ecological analysis of research and management.
The American mink
was originally introduced to the UK from its homeland across the Atlantic for its fur.
In the following work, the potential biological effect (including molecular phenotype) of nucleotide variation within the growth hormone gene in American mink
(Neovison vison Schreb., 1777) was evaluated, based on multilocus genotypes of 389 individuals (wild mink from Canada, six colour types of ranch mink, mink acquired from the natural environment in Poland and Iceland), identified by direct sequencing.
About twice as large as our American mink
, chunkier and noticeably redder, they swam visibly, diurnally hunting for seabirds, eggs and shellfish.
