Meehan, C. L., Hogan, J. N., Bonaparte-Saller, M. K. et al. 2016. Housing and social environments of African (Loxodonta africana) and Asian (Elephas maximus) elephants in North American zoos. PLOS ONE 11(7), e0146703.

We evaluated 255 African (Loxodonta africana) and Asian (Elephas maximus) elephants living in 68 North American zoos over one year to quantify housing and social variables. All parameters were quantified for the both the day...

Yamanashi, Y., Teramoto, M., Morimura, N. et al. 2016. Effects of relocation and individual and environmental factors on the long-term stress levels in captive chimpanzees (Pan troglodytes): Monitoring hair co

Understanding the factors associated with the long-term stress levels of captive animals is important from the view of animal welfare. In this study, we investigated the effects of relocation in addition to individual and environmental...

Holdgate, M. R., Meehan, C. L., Hogan, J. N. et al. 2016. Walking behavior of zoo elephants: Associations between GPS-measured daily walking distances and environmental factors, social factors, and welfare indicators. PLOS ONE 11(7), e0150331.

Research with humans and other animals suggests that walking benefits physical health. Perhaps because these links have been demonstrated in other species, it has been suggested that walking is important to elephant welfare, and that...

Greco, B. J., Meehan, C. L., Hogan, J. N. et al. 2016. The days and nights of zoo elephants: Using epidemiology to better understand stereotypic behavior of African elephants (Loxodonta africana) and Asian elephants (Elephas maximus) in North A

Stereotypic behavior is an important indicator of compromised welfare. Zoo elephants are documented to perform stereotypic behavior, but the factors that contribute to performance have not been systematically assessed. We collected behavioral data on 89...

Brown, J. L., Paris, S., Prado-Oviedo, N. A. 2016. Reproductive health assessment of female elephants in North American zoos and association of husbandry practices with reproductive dysfunction in African Elephants (Loxodonta africana).

As part of a multi-institutional study of zoo elephant welfare, we evaluated female elephants managed by zoos accredited by the Association of Zoos and Aquariums and applied epidemiological methods to determine what factors in the...

Ceja, C., White, J. 2010. Feeding behavior of Saguinus oedipus in relation to food hardness in a zoo setting: Possibilities for enrichment? Laboratory Primate Newsletter 49(3), 10-13.

We suggest that by providing animals with food in a more natural form (i.e., not cut to a standardized size), they would have an opportunity to process the food in a manner that best approaches...

Hoy, J. M., Murray, P. J., Tribe, A. 2010. Thirty years later: Enrichment practices for captive mammals. Zoo Biology 29(3), 303-316.

Environmental enrichment of captive mammals has been steadily evolving over the past thirty years. For this process to continue, it is first necessary to define current enrichment practices and then identify the factors that limit...

Leonardi, R., Buchanan-Smith, H. M., Dufour, V. et al. 2010. Living together: Behavior and welfare in single and mixed species groups of capuchin (Cebus apella) and squirrel monkeys (Saimiri sciureus). American Journal of Primatology 72(1), 33-47.

There are potential advantages of housing primates in mixed species exhibits for both the visiting public and the primates themselves. If the primates naturally associate in the wild, it may be more educational and enjoyable...
