The material
for the writing of this article is based on the
observation of animals hunted by domestic cats.
The hamsters were immobilized and killed by the
predators mostly by biting through the spine at
the back of the neck. Regarding the dispersal of
melanistic forms, it has been established that today
the boundary of the Podillia segment of the species’
range is much further to the west of the point determined
by V. Samosh (1978), which suggests the idea about
the expansion of the distribution range of melanistic
variants. The results of the study of quantitative
parameters of the hamster population show that the
density of inhabited burrows and the activity of
their use decrease from perennial grasses, crops,
and motley grass crops to gardens and areas overgrown
by weeds. A colony of this rodent was found on the
banks of the Strypa River as well. |
