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)
Journal Article
Casar, C., Byrne, R., Young, R., & Zuberbuhler, K. (2012). The alarm call system of wild black-fronted titi monkeys, Callicebus nigrifrons. Behavioral Ecology and Sociobiology, 66, 653-667. https://doi.org/10.1007/s00265-011-1313-0

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...

Feeding and social behavior of the piabanha, Brycon devillei (Castelnau, 1855)(Characidae: Bryconinae) in the wild, with a note on following behavior (2011)
Journal Article
Azevedo, P., Melo, R., & Young, R. (2011). Feeding and social behavior of the piabanha, Brycon devillei (Castelnau, 1855)(Characidae: Bryconinae) in the wild, with a note on following behavior. #Journal not on list, 9(4), https://doi.org/10.1590/S1679-62252011005000046

Knowledge concerning the behavior of wild freshwater fishes in Brazil is restricted to a few studies, despite such studies being able to answer fundamental questions about conservation. Species of Brycon are amongst the most threatened in the Neotrop...

Designing laboratory marmoset housing: What can we learn from urban marmosets? (2011)
Journal Article
Duarte, M., Goulart, V., & Young, R. (2012). Designing laboratory marmoset housing: What can we learn from urban marmosets?. Applied Animal Behaviour Science, 137(3-4), 127-136. https://doi.org/10.1016/j.applanim.2011.11.013

How to house animals in captivity, so as to maximise their level of well-being, is one of the greatest practical challenges facing animal welfare scientists. Laboratory animal housing can, necessarily, be very restrictive in terms of the facilities b... Read More about Designing laboratory marmoset housing: What can we learn from urban marmosets?.

Behavioral responses of maned wolves (Chrysocyon brachyurus, Canidae) to different categories of environmental enrichment stimuli and their implications for successful reintroduction (2011)
Journal Article
Coelho, C., de Azevedo, C., & Young, R. (2012). Behavioral responses of maned wolves (Chrysocyon brachyurus, Canidae) to different categories of environmental enrichment stimuli and their implications for successful reintroduction. Zoo Biology, 31(4), 453-469. https://doi.org/10.1002/zoo.20410

The maned wolf (Chrysocyon brachyurus, Illiger, 1815, Canidae) is a threatened species that inhabits the cerrados of Brazil, Argentina, Peru, Bolivia, Paraguay, and Uruguay. Captive maned wolves could be potentially used in reintroduction programs fo...

Noisy human neighbours affect where urban monkeys live (2011)
Journal Article
Duarte, M., Vecci, M., Hirsch, A., & Young, R. (2011). Noisy human neighbours affect where urban monkeys live. Biology Letters, 7(6), https://doi.org/10.1098/rsbl.2011.0529

Urban areas and many natural habitats are being dominated by a new selection pressure: anthropogenic noise. The ongoing expansion of urban areas, roads and airports throughout the world makes the noise almost omnipresent. Urbanization and the increas...

Human--marmoset interactions in a city park (2011)
Journal Article
Leite, G., Duarte, M., & Young, R. (2011). Human--marmoset interactions in a city park. Applied Animal Behaviour Science, 132(3-4), 187-192. https://doi.org/10.1016/j.applanim.2011.03.013

Urban wildlife, frequently, comes into contact with human city dwellers and these interactions can be viewed positively or negatively by people. In the city of Belo Horizonte (Minas Gerais, Brazil) many city parks have groups of black-tufted marmoset... Read More about Human--marmoset interactions in a city park.

Cortisol Circadian Rhythm Ratio: A Simple Method to Detect Stressed Horses at Higher Risk of Colic? (2011)

Domestic cats are known to kill small mammals and birds, and represent a predatory threat to all small wildlife. We investigated whether a high cat density affects the choice of sleeping sites of urban marmosets (Callithrix penicillata). One group of...
