de Azevedo, C., Lima, M., da Silva, V., Young, R., & Rodrigues, M. (2012). Visitor influence on the behavior of captive greater rheas (Rhea americana, Rheidae Aves). Journal of Applied Animal Welfare Science, 15(2), https://doi.org/10.1080/10888705.2012.624895

Visitors can affect and reduce the welfare of nonhuman animals. The Belo Horizonte Zoo, Brazil, had a group of greater rheas intended for reintroduction to the wild. Because this group received public visitation, evaluating its effect on the birds' b... Read More about Visitor influence on the behavior of captive greater rheas (Rhea americana, Rheidae Aves).

International Zoo Yearbook, 47(1), 163-170. https://doi.org/10.1111/j.1748-1090.2012.00195.x

Animals kept by zoos may express abnormal behaviours that are indicators of poor welfare. Environmental enrichment is a technique of providing items to animals that stimulate the expression of normal behaviours. The aim of this study was to evaluate...

Evidence for semantic communication in titi monkey alarm calls (2012)
Journal Article
Casar, C., Byrne, R., Hoppitt, W., Young, R., & Zuberbuhler, K. (2012). Evidence for semantic communication in titi monkey alarm calls. Animal Behaviour, 84(2), 405-411. https://doi.org/10.1016/j.anbehav.2012.05.010

Black-fronted titi monkeys, Callicebus nigrifrons, produce acoustically distinct vocalizations in response to several predator species. Compared to other primates, the calls are remarkably quiet, high-pitched and structurally simple, suggesting that... Read More about Evidence for semantic communication in titi monkey alarm calls.

The welfare of an unwanted guest in an urban environment: the case of the white-eared opossum (Didelphis albiventris) (2012)
Journal Article
Sousa, C., Teixeria, C., & Young, R. (2012). The welfare of an unwanted guest in an urban environment: the case of the white-eared opossum (Didelphis albiventris). Animal Welfare Journal, 21(2), https://doi.org/10.7120/09627286.21.2.177

One major problem facing wildlife is urbanisation, and the increasing contact between human city dwellers and animals. In this study, we investigated the problems of urban opossums (Didelphis albiventris), through the analysis involving responses to...

Failure of captive-born greater rheas (Rhea americana, Rheidae, Aves) to discriminate between predator and nonpredator models (2012)
Journal Article
de Azevedo, C., Young, R., & Rodrigues, M. (2012). Failure of captive-born greater rheas (Rhea americana, Rheidae, Aves) to discriminate between predator and nonpredator models. Acta ethologica, 15, 179-185. https://doi.org/10.1007/s10211-012-0124-2

The capacity to recognize and respond to predators can be lost by captive animals. Habituation to humans caused by the captive environment can be transferred to other stimuli, such as predators, a situation that conservation biologists wish to avoid....

Black-fronted titi monkeys, Callicebus nigrifrons, are endemic primates of the Atlantic forest of Brazil, and little is known about their diet and how it is affected by seasonal changes. The aim of this study is to analyze the diet of C. nigrifrons d... Read More about The diet of wild black-fronted titi monkeys Callicebus nigrifrons during a bamboo masting year.

The alarm call system of wild black-fronted titi monkeys, Callicebus nigrifrons (2012)

Upon encountering predators, many animals produce specific vocalisations that alert others and sometimes dissuade the predators from hunting. Callicebus monkeys are known for their large vocal repertoire, but little is known about the function and me...
