Abstract
Patterns of relation between environmental filtering and competition, structuring assemblages of ecologically similar rodents, remain unclear. Thereupon we studied population density of mice and voles of Prikhanakaya Plain. We find their population variability limits describing habitat preferences. It was shown that populations of the harvest mouse, the gray red-backed vole and the northern red-backed vole, and also probably the Korean field mouse and the stripped field mouse, depend on warm-/humidity-supply, while their competition don’t influence structure of the rodent assemblage studied. We discuss its functioning mechanism and probable transformation trends through global change.
