"A comparison of two methods for interpolating the tracks of
primates:
linear weighted distance and constrained random walk"
Abstract.
| The goal of this paper is to implement and to test two
interpolation techniques that create continuous tracks of two primate species (Ateles geoffroyi, the red spider monkey, and Cebus capucinis, the white-faced capuchin). Continuous tracks were needed to calculate overall home range and to analyze the daily ranging patterns for each species. Establishing continuous tracks of primates through field data alone, however, was impossible due to challenging field conditions. A need arose to estimate their positions when their actual position was unknown. The results of the analysis using tracks with interpolated positions confirmed that Ateles tend to move directly to their destination while Cebus tended to follow a more wandering track. |
