Abstract
SynopsisIn the red deer population of the Isle of Rhum, the effects of increasing population density on reproduction and survival vary with the individual's sex, age. reproductive status, home-range quality, group size and social rank. Males are generally more strongly influenced than females. Within both sexes, individuals that are at an initial competitive disadvantage are generally most strongly influenced by rising density.These differences are likeh to have far-reaching consequences. In particular, they may help to explain why dense deer populations commonly have female biased adult sex ratios: why calculations of maximum sustainable yield commonh overestimate the number of animals that can be culled; and why some populations that are not subiect to animal or human predation stabilize while others oscillate.
