Place of publishing:

Białowieża

Description:

Earlier studies have shown that there is a predominance of females in the adult component of peak Microtus agrestis populations. The present studies included three areas in which the populations respectively reached a two year peak, a one year peak and showed no cyclic behavior at all. Each peak was associated with a surplus of females around midsummer which was apparently due to more rapid maturation or higher survival rate in female than male spring-boring animals. Wcześniej wykazano, że w fazie szczytu liczebności wśród dorosłych osobników przeważają samice. Obecnie zbadano stosunek płci w trzech populacjach M. agrestis różniących się charakterem fluktuacji. Pierwsza osiągała szczyt liczebności co 2 lata, druga rokrocznie a trzecia nie wykazywała żadnej cykliczności (Ryc. 1). Wykazano, że każdy szczyt liczebności związany jest w środku lata z nadwyżką samic (Tabela 1 i 2), która przypuszczalnie wiąże się z szybszym ich dojrzewaniem lub wyższym stosunkiem przeżywania samic, w porównaniu z urodzonymi równiez na wiosnę samcami (Ryc. 2).
