The article presents information on the ecology of pine voles in the highlands of the Carpathians based on the results of studies conducted in 1956–1986. The results of population surveys in different types of habitats and plant associations are presented, with corresponding estimates of abundance (maximum 123 specimens/ha) and density (maximum 2.6 kg/ha), as well as an analysis of population features in different habitats and different years. The high frequency of the species occurrence in ruderal coenoses of the highlands, in particular in thickets of the alpine sorrel, is shown. Detailed information on the reproduction of populations, in particular on the number of young in a litter, is given: the modal value is 2–3, the limits are 1–5, and the average is 2.4–2.9, depending on the biotope (plant association). Data on the ratio of reproductively active individuals and the age and sex structure of populations, as well as the ecomorphological and ecophysiological parameters of voles are presented. |
