| Investigations were conducted in the Lipetsk region in 1987-1997 and 2001-2007. The patterns of the pygmy
wood mouse population dynamics have been studied using time-series analysis. The observed population magnitude
changes have been found to represent a complex process having a trend and a cyclical component with a period
of one year. The structure and variations of the population with the period of one year are
determined by the adaptation to the seasonal changes of environmental factors. The exogenous (weather)
factors limit the growth of population. These factors are most effective during autumn-winter and spring-summer
periods. |
