摘要

Based on data obtained over a period of 11 years from female ring-tailed lemurs (Lemur catta), we analyzed the correlation between group size and female reproductive parameters. The birth rate and mean number of surviving infants 1 year after birth per adult female generated an inverted U-shaped curve when plotted against group size (although not significant) and number of adult female members. Infant mortality rate did not have a consistent correlation with group size and number of adult female members. Thus, our findings were similar to the predictions of Wrangham’s inter-group feeding competition hypothesis.
