Is Chimpanzee (Pan Troglodytes) Wounding Frequency Affected By The Presence Versus Absence Of Visitors? A Multi-Institutional Study, Robin Elana Salak, Christina Cloutier Barbour

Student Published Works

Visitor effect studies have had inconsistent results, due in part to the inability to control for all confounding variables such as time of day, seasonal weather patterns, and so forth. This study represents the first instance where chimpanzee (Pan troglodytes) wounding frequencies were investigated across extensive time periods in the presence and complete absence of visitors, thus eliminating many visitor-related variables. Additional variables were eliminated through the zoo selection process, based on institutional responses to a 29-question survey, providing a novel approach to the question of visitor effects. The aim of this study was to determine if visitors …
