[Spatial-temporal dynamics of the pine marten (Martes martes L.), mountain hare (Lepus timidus L.) and red squirrel (Sciurus vulgaris L.) trail activity in the European southern taiga].

Observations of trail activity of the martens, mountain hares, and red squirrels in winter along fixed routes in the Central Forest Reserve showed its high variability and synchronism in time and space. Polynomial dependence of the trail activity and correlation between spatial distribution of marten, mountain hare and squirrel are detected. The influence of weather on the trail activity is smaller, but statistically significant.
