Résumé

Forested edges, especially those that border humanized landscapes, provide opportunities for nonhuman primates and people to interact, and such interactions are predicted to alter disease dynamics. Given the rapid expansion of edge habitats globally, understanding changes occurring on edges is important in evaluating primate behavioral ecology and developing conservation plans. Our research investigates predictions concerning how gastrointestinal parasite and stress levels (cortisol) in red colobus and black-and-white colobus (Procolobus rufomitratus; Colobus guereza) in Kibale National Park, Uganda, differ between humanized and nonhumanized forest edges. We found Trichuris sp., an unidentified strongyle, and Strongyloides sp. in the fecal samples. Results did not generally support our expectation that humanized forest edges increase parasite infection and, counter to what we predicted, fecal cortisol did not differ between habitats, suggesting that proximity to edges and/or to humans did not result in increased stress. We conclude that broad habitat classifications, e. g., "humanized," may be too general to identify consistent differences in parasite infection, as other factors, specific to the parasite (e. g., life cycled), host (e. g., immune systems strength), or environment (e. g., moisture level), likely also play important roles. © 2012 Springer Science+Business Media, LLC.
