Age variation in a fluctuating population of the common vole.

Popis výsledku v původním jazyce

We analysed variation in age in a fluctuating population of the common vole (Microtus arvalis) in southern Moravia to test the assumption of the senescence hypothesis that the age of voles increases with increasing population density. Between 1996 and 1998, we monitored the demographic changes by snap-trapping and live-trapping in a field population passing through the increase, peak and decline phase of the population cycle. We used the eye lens mass method to determine the age of snap-trapped and live-trapped animals. The average age of winter males was higher after the peak phase breeding season than before it. No such phase-dependent shift in age was observed in the female component. Male age continued to increase from autumn to spring over the pre-peak winter, and the highest age was in spring of the peak phase year. After the peak phase breeding season the highest age was achieved in winter, with the decline phase males during the next spring tending to be younger.
