Abstract
On the basis of the results of long-term monitoring of water vole populations in northern Baraba (Ubinskoye district of the Novosibirsk Region), a connection between water flow intensity in the Om river in the region under investigation, magnitude of population, its seasonаl variations from May to August, average number of living embryos in over-wintered females and the fraction of young females of the current year entering reproduction for different years is investigated.
