A case of adoption in a wild group of black-fronted titi monkeys (Callicebus nigrifrons) (2007)
Journal Article
Casar, C., & Young, R. (2008). A case of adoption in a wild group of black-fronted titi monkeys (Callicebus nigrifrons). Primates, 49, 146-148. https://doi.org/10.1007/s10329-007-0066-x

We observed a case of infant adoption in an unprovisioned group of wild black-fronted titi monkeys (Callicebus nigrifrons). During our long-term field study we noticed that an infant had moved from one of our study groups (“Desbotado”) to another (“R...

Observed case of maternal infanticide in a wild group of black-fronted titi monkeys (Callicebus nigrifrons) (2007)
Journal Article
Casar, C., Franco, E., Soares, G., & Young, R. (2007). Observed case of maternal infanticide in a wild group of black-fronted titi monkeys (Callicebus nigrifrons). Primates, 49, 143-145. https://doi.org/10.1007/s10329-007-0067-9

A maternal infanticide was observed in a group of unprovisioned wild black-fronted titi monkeys (Callicebus nigrifrons). An approximately 3-day-old male infant was killed by his mother. A post-mortem revealed the infant to be clinically healthy. We c... Read More about Observed case of maternal infanticide in a wild group of black-fronted titi monkeys (Callicebus nigrifrons).

The behavioural responses of Nile tilapia (< i> Oreochromis niloticus</i>) to anti-predator training (2007)
Journal Article
Mesquita, F., & Young, R. (2007). The behavioural responses of Nile tilapia (< i> Oreochromis niloticus) to anti-predator training. Applied Animal Behaviour Science, 106(1-3), 144-154. https://doi.org/10.1016/j.applanim.2006.06.013

Globally millions of fishes are released, each year, into the wild to supplement diminishing populations. However, research indicates that less than 5% of these individuals survive, and that one of the major causes of mortality is predation. The obje...

A preliminary study into the effectiveness of stroboscopic light as an aversive stimulus for fish (2007)
Journal Article
Mesquita, F., Godinho, H., de Azevedo, P., & Young, R. (2008). A preliminary study into the effectiveness of stroboscopic light as an aversive stimulus for fish. Applied Animal Behaviour Science, 111(3-4), 402-407. https://doi.org/10.1016/j.applanim.2007.06.014

To reduce fish mortality in nature it is often necessary to expel individuals from areas modified by humans (e.g., dams) where they could be injured or killed. We tested the effectiveness of stroboscopic light as an aversive stimulus for zebrafish (D...

A note on the use of GPS collars to monitor wild maned wolves< i> Chrysocyon brachyurus</i>(Illiger 1815)(Mammalia, Canidae) (2007)
Journal Article
Coelho, C., de Melo, L., Sabato, M., Rizel, D., & Young, R. (2007). A note on the use of GPS collars to monitor wild maned wolves< i> Chrysocyon brachyurus(Illiger 1815)(Mammalia, Canidae). Applied Animal Behaviour Science, 105(1-3), 259-264. https://doi.org/10.1016/j.applanim.2006.04.024

Increasingly, problems of animal conservation are being solved with the aid of technology. One recent advance in monitoring the spatial location of wild animals is the GPS collar. In this study we evaluate the use of such technology with three wild m...

Environmental enrichment: a GAP analysis (2007)
Journal Article
de Azevedo, C., Cipreste, C., & Young, R. (2007). Environmental enrichment: a GAP analysis. Applied Animal Behaviour Science, 102(3-4), 329-343. https://doi.org/10.1016/j.applanim.2006.05.034

GAP analyses are tools used to inform us about the short-comings of a scientific area or necessities in social–economic problems. In the last 20 years, environmental enrichment as an area of scientific investigation has come of age; this can be clear... Read More about Environmental enrichment: a GAP analysis.

Socio-sexual behavior of female northern muriquis (Brachyteles hypoxanthus) (2007)
Journal Article
Possamai, C., Young, R., Mendes, S., & Strier, K. (2007). Socio-sexual behavior of female northern muriquis (Brachyteles hypoxanthus). American Journal of Primatology, 69(7), 766-776. https://doi.org/10.1002/ajp.20399

Female northern muriquis (Brachyteles hypoxanthus) are known to engage in frequent copulations with multiple partners, a pattern that in other primates has been attributed to various functions such as confusing paternity, reducing male aggression, or...
