The
European Polecat (
Mustela putorius), also known as a
fitch, is a member of the
Mustelidae family, and is related to the
stoats,
otters,
weasels, and
minks. They are dark brown with a lighter bandit-like mask across the face, pale yellow underbody fur, a long tail and short legs. They are somewhat larger than
weasels, weighing between 0.7 kg for females to 1.7 kg for males, but smaller than
otters.
Polecats live in most of the countries of Europe. They are mainly nocturnal and usually found in woodlands, farmlands, and wetlands. They often make dens in stream banks or under tree roots. Mainly carnivorous, they feed largely on
frogs and voles, but will also catch rats and other small prey. They require a home range of about a square kilometer. The pattern of
polecat predation on
frogs was found to be sex selective and predation by
polecats is found to influence sex ratio, male abundance and sexual conflict in a
frog mating system, restricting the opportunity for multiple mating (see Thierry Lod??).
Polecats (mainly dark phenotype) are able to hybridize with the rare
European mink and have fertile hybrids (see Lod?? Thierry, Journal of Heredity). In some parts of England, the abandoning of domestic
ferrets has led to
ferret-
polecat hybrids living in the wild that are almost indistinguishable from pure
polecats. Although
Polecats were chiefly polygynous, but females could show polyandry and, related to sexual conflict, the mating system could change with environmental conditions. Note that sexual conflict may result into sexually antagonistic co-evolution, in which one sex evolves a "manipulative" character which is countered by a "resistance" trait in the other sex. Deliberate homosexuality was also observed (Thierry Lod??) in wild
polecats.
Other species of
polecat include the
Steppe Polecat (M. eversmanni) and the
European Mink (M. lutreola). Most zoologists believe that the domestic
ferret (M. putorius furo) is descended from the
European Polecat, or possibly from a hybrid of the European and steppe varieties. The Zorilla, also called the
striped polecat (
Ictonyx striatus), lives in subsaharan Africa.
