- W2185959643 abstract "The spring population density of European sousliks ( Spermophilus citellus) in a suburban area near Vienna, Austria, changed from 60 to 6 individuals/ha from 1991 to 1998. The decline occurred during the active seasons of 1994 and 1995. In order to investigate effects of population density on reproduction we examined ma- le mating effort and success. Male home-range size, intrasexual aggression, mass loss during the mating period, and individual reproductive success changed with population density. Home-range size increased with density de- cline, whereas aggression and mass loss decreased. High densities were characterized by more intense male- male competition and a skewed distribution of mates per male. Mate numbers in low-density situations were nor- mally distributed and all males were able to acquire at least one mate. At low density, all yearling males were reproductively active compared to only 13% in the high-density years. Mature yearlings had lower growth rates than non-reproductive ones. Analyses of cortisol secretion indicated high stress levels at low density throughout the season. These changes could be viewed as a facultative response to changes in mate availability and the dis- tribution of reproductive success. On the other hand, the costs of reproduction could be amplified by precocious- ness associated with population density changes." @default.
