Description:

A study of the energy flow through a population of the common hamster Cricetus cricetus (L i n n a e u s, 1758) and its impact on crops was carried out in cultivated fields, 128 ha in area, in the Vistula valley, about 80 km east of Cracow. The population dynamics of these rodents, their activity rhythm, and the climatic parameters were determined in a field study. The average daily metabolic rate (ADMR) and chemical thermoregulation (RMR) were measured in the laboratory, where the composition of their natural diet and the consumption and utilization of foods were also estimated. Badania nad przepływem energii przez populację chomików (L i n n a e u s, 1758) oraz ich wpływem na uprawy prowadzono na 128 ha pól leżących w dolinie Wisły - 80 km od Krakowa (Ryc. 1). Liczebność dorosłych chomików określano wiosną i jesienią każdego roku przez liczenie czynnych nor (Tabela 1). Średnie roczne zagęszczenie dorosłych zwierząt wynosiło 8,5/ha. Po uwzględnieniu młodych zwierząt, których ilość oszacowano z liczby embrionów całkowite zagęszczenie wynosi rocznie średnio 12,4 chomików/ha (Ryc. 2). Na podstawie zależności ciężarów ciała i ciężarów soczewek oka chomików ustalono strukturę wiekową tych gryzoni (Ryc. 3, Tabele 2, 3, 4). Z kolei pozwoliło to na ułożenie tabel życia populacji chomików (Tabela 5, Ryc. 4).
