Primate Body Size–Home Range Relationships; A Comparison between Four Locomotive Techniques.

Claire Bennett

Abstract


Primates have an intricate relationship with their environment. Previous studies have demonstrated that there is a positive correlation of primate body size and home range. Inasmuch biological characteristics such as body size and locomotion style  be characteristics which influence how primates use their surrounding environment to create home ranges. In this paper the author critically analysed research and bodies of data to locate body size and home range information for sixteen primate species. The primates that were selected were divided into four locomotor styles; arboreal quadrupedalism, terrestrial quadrupedalism, leaping and suspensory locomotion. Graphs and statistics were generated to determine if there were any patterns between body size and home range. Once graphs were created a comparison between locomotor types was feasible. The data demonstrated that only vertical clinging and leaping species demonstrated a strong positive body size vs. home range relationship. Although strong correlations did not exist between the other locomotor types it is likely that the sample size was too small and more data points are needed in future studies. Another possibility to explain the results is that non-leapers have their body size and home range affected by other biological, ecological or behavioural factors. The study reveals where more analysis is needed and what the next steps are in understanding body size and home range correlations.
