Intrapopulation variability and intrapopulation differenciation (an example of five species of the orger Carnivora)

Intrapopulation variability and intrapopulation differentiation of five carnivoran species: American mink Neovison vison, European mink Mustela lutreola L., polecat Mustela putorius L., pine marten Martes martes L., and raccoon dog Nyctereutes procyonoides were investigated. It is shown that species with high level of variability (American mink, polecat, raccoon dog) are characterized by better intrapopulation structuring. The degree of differences between groups is not deep, and does not depend on the distance; it is determined by the combination of endogenic and abiotic factors.
