The spatiotemporal structure of population in the Muskrat (Ondatra zibethicus)

  • Yu. A. Gorshkov


The spatiotemporal structure of the muskrat population has been studied by means of the prenatal radioactive marking of juveniles with 45 Ca and their subsequent recapture in the test area. The muskrat population is characterized by a cyclic type of spatial structure, with seasonal transition from a mosaic type of settling to a diffuse type and, after the breeding season, vice versa.

Key words
