Effects of territory size on the reproductive success and social system of the giant otter, south-eastern Peru: Territory size and reproductive success in giant otters

Abstract

The link between resource abundance, dispersion and cooperative breeding in mammals has been a topic of much debate among ecologists. The giant otter social system is facultatively cooperative…. We conclude that giant otter societies are likely shaped by the spatial dispersion of lakes, and food abundance and dispersion within these rich patches.
