Abstract: | Long-term (1985–1999) stationary observations on a polymorphic population of northern mole voles (Ellobius talpinus Pall.) in Kurgan oblast, Russia, using a mark-recapture method yielded original data on the population dynamics and population
structure of a polymorphic colony consisting of animals of three color morphs (black, brown, and intermediate or transitional).
The period when the northern mole vole population dynamics was studied (15 years) consisted of five distinct three-year population
phases: depression, growth, peak (stabilization), decline to depression, and the next growth phase. It was shown that the
population dynamics and changes in the population structure of northern mole voles in the Kurtamysh colony are cyclic. |
