Home ranges of predators and small sources of marine biomass

Sergio Cobarrubia-Russo

The meaning of the ecological term home range defines an important ecological aspect of mobile animals and has "evolved" in an attempt to project the most comprehensive definition. In a study of home ranges and ranges of two species of coastal dolphins and fishermen on the western coast of Aragua, Venezuela, South Caribbean, it was observed that these three species coincided in a specific area, so that a spatial analysis determined a small and important source of biomass that provides prey throughout the year for dolphins, fishermen and local people. This note aims to highlight the ease of defining these areas and their conservation importance as sources of protein for humans and other predators.
