Journal Article
Hinchcliffe, D., Young, R., & Teixeira, C. (2022). Callout analysis in relation to wild birds in a tropical city: implications for urban species management. Urban Ecosystems, 25(6), 1643-1652. https://doi.org/10.1007/s11252-022-01256-1

Urbanisation is changing landscapes at an unprecedented rate, which consequently changes species compositions. We investigate problems faced by urban birds in a neotropical city by analysing the responses made to callouts by the environmental police...

Journal Article
de Faria, C., de Souza Sá, F., Lovenstain Costa, D., da Silva, M., da Silva, B., Young, R., & de Azevedo, C. (2020). Captive-born collared peccaries learning about their predators : lessons learnt but not remembered. Behavioural Processes, 171, 104031. https://doi.org/10.1016/j.beproc.2019.104031

Captive-born animals frequently lose their anti-predatory abilities due to the absence of encounters with their predators, but these abilities can be regained through specific training. Anti-predator training can, thus, enhance the success of reintro... Read More about Captive-born collared peccaries learning about their predators : lessons learnt but not remembered.
