Who do male chimpanzees defend a group range?

Article Abstract:

Eighteen years of observational data on the Gombe chimpanzees is examined to determine the behavior of males during extra group encounters, and the consequences of change in community range size on the number of adult females and indirect measures of food availability. The findings suggest that males defend a feeding territory for their resident females and protect them from sexual harassment.
