Black rhinoceros (Diceros bicornis) in U.S. zoos: I. individual behavior profiles and their relationship to breeding success
Abstract This is the first part of a multi-zoo study to analyze the effects of captive environments on black rhinoceros (Diceros bicornis) behavior, breeding success, and well-being. We estimated the reliability and validity of a standardized method of cross-institutional assessment of the behavior of individual rhinoceros. In 1994 and 1995, we asked zookeepers at 19 […]
Black rhinoceros (Diceros bicornis) in U.S. zoos: II. behavior, breeding success, and mortality in relation to housing facilities

This can only be achieved by cross-institutional analyses of environments, behavior, and performance. In this study, we collected data on 23 zoos with black rhinoceros to compare zoo environments with reproductive […]
