Do wild titi monkeys show empathy? (2014)
Journal Article
Clyvia, A., Kaizer, M., Vale, R., Young, R., & Casar, C. (2014). Do wild titi monkeys show empathy?. Primate Biology, 1, 23-28. https://doi.org/10.5194/pb-1-23-2014

We observed a putative case of empathy among wild black-fronted titi monkeys (Callicebus nigrifrons) from two different groups (D and R). In over 10 years of behavioural observations of five habituated groups of this species, only low levels of int... Read More about Do wild titi monkeys show empathy?.

Demographic and growth analysis of broad snouted caiman (Caiman latirostris) in a disturbed environment in southeastern Brazil (2014)
Journal Article
southeastern Brazil. Herpetological journal, 24(4), 223-228

Crocodilian life history traits exhibit strong size and age dependence, which is determined, ultimately, by how fast individuals grow. Crocodilian population dynamics are dependent on environmental conditions such as local temperatures and hydrology...

Exercising for food : bringing the laboratory closer to nature (2014)
Journal Article
Fonseca, I., Passos, R., Araujo, F., Lima, M., Lacerada, D., Pires, W., …Rodrigues, L. (2014). Exercising for food : bringing the laboratory closer to nature. Journal of Experimental Biology, 217, 3274-3281. https://doi.org/10.1242/jeb.108191

Traditionally, exercise physiology experiments have borne little resemblance to how animals express physical activity in the wild. In this experiment, 15 adult male rats were divided into three equalsized groups: exercise contingent (CON), non-exe...

Rapid animal welfare assessment : an archaeological approach (2014)
Journal Article
Schork, I., & Young, R. (2014). Rapid animal welfare assessment : an archaeological approach. Biology Letters, 10, 20140390. https://doi.org/10.1098/rsbl.2014.0390

The welfare of an individual depends on its capacity to overcome suboptimal conditions in its environment; otherwise, its physical and psychological health becomes compromised. A situation that clearly indicates lack of control of the environment... Read More about Rapid animal welfare assessment : an archaeological approach.

Can enrichment make Brazilian tapir spend more time on view to the public? (2014)
Journal Article
more time on view to the public?. Journal of Applied Animal Welfare Science, 18, 74-81. https://doi.org/10.1080/10888705.2014.945177

One common visitor complaint in zoos is that the nonhuman animals are not visible. This problem needs to be resolved without compromising the animals’ welfare; environmental enrichment could solve the problem. This study investigated whether enrich...

Behavioural and ecological aspects of black tufted-ear marmosets, Callithrix penicillata (Geoffroy, 1812) (Primates: Callitrichidae) in a semi- urban environment (2014)
Journal Article
Nogueira, M., Santos, D., Henriques, M., Duarte, L., & Young, R. J. (2014). Behavioural and ecological aspects of black tufted-ear marmosets, Callithrix penicillata (Geoffroy, 1812) (Primates: Callitrichidae) in a semi- urban environment. #Journal not on list, 13, 37-46

O mico-estrela (Callithrix penicillata) é uma pequena espécie de primata neotropical que vive em vários tipos de ambientes como Cerrado e Mata Atlântica, podendo também ocupar áreas urbanas. Pesquisas já mostraram que a disponibilidade de recurso ali...

Enriching Tortoises: assessing color preference (2014)
Journal Article
Passos, L., Melo, H., & Young, R. (2014). Enriching Tortoises: assessing color preference. Journal of Applied Animal Welfare Science, 17(3), 274-281. https://doi.org/10.1080/10888705.2014.917556

Environmental enrichment is a principle that is used to enhance the quality of care for nonhuman animals in captivity. To achieve this, it is necessary to understand the animal’s needs. This study focused on color preference to provide food stimuli... Read More about Enriching Tortoises: assessing color preference.

Behavioural and ecological aspects of black tufted-ear marmosets, Callithrix penicillata (Geoffroy, 1812) (Primates: Callitrichidae) in a semi-urban environment (2014)
Journal Article

The black tufted-ear marmoset (Callithrix penicillata) is a small Neotropical primate, which lives in various types of environments from Cerrado (Brazilian savannah), Atlantic forest to urban areas. Research shows that food availability influences ho...

Zoo visitor effect on mammal behaviour : does noise matter? (2014)
Journal Article
Quadros, S., Goulart, V., Passos, L., Vecci, M., & Young, R. (2014). Zoo visitor effect on mammal behaviour : does noise matter?. Applied Animal Behaviour Science, 156, 78-84. https://doi.org/10.1016/j.applanim.2014.04.002

The zoo visitor effect is the change in animal behaviour and physiology in response to the presence of a viewing public. It is thought to result from, amongst other things, visitor generated sound (i.e., noise), but this hypothesis has never been e...
