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...

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...

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...

Titi monkey call sequences vary with predator location and type (2013)
Journal Article
Casar, C., Zuberbulher, K., Young, R., & Byrne, R. (2013). Titi monkey call sequences vary with predator location and type. Biology Letters, 9(5), 20130535. https://doi.org/10.1098/rsbl.2013.0535
