Demographic parameters and variations in numbers of the common vole
Observations were made for two years of the demographic variations in two enclosed populations (A i B) of the common vole Microtus arvalis (Pallas, 1779) by means of the CMR method. Variations in numbers followed a similar course in both populations, population A reaching a lower maximum number than...

Summary: | Observations were made for two years of the demographic variations in two enclosed populations (A i B) of the common vole Microtus arvalis (Pallas, 1779) by means of the CMR method. Variations in numbers followed a similar course in both populations, population A reaching a lower maximum number than B. Both populations were more numerous in the second study year (1972).Przy pomocy metody CMR rejestrowano przez dwa lata zmiany demograficzne dwóch (A i B) zamkniętych populacji Microtus arvalis (Pallas, 1977). Zmiany liczebności w obu populacjach przebiegały podobnie.
