Prenatal androgens are responsible for sex differences in behaviour and morphology in many species, causing changes in neural structure and function that persist throughout life. Some variation in the expression of behaviour between individuals of th...

Primate species are characterised by variation in foraging behaviour and dietary composition across their geographic range. Here we examine how ecological conditions account for variation in the behavioural ecology of a widespread arboreal guenon, Ce...

A comparison of heterosexual and homosexual mating preferences in personal advertisements (2014)
Journal Article

Human heterosexual mating preferences have been shown to conform to predictions drawn from evolutionary theory, with men and women adopting broadly distinct strategies. Attempts to reconcile sexual selection theory with homosexual behaviour have been... Read More about A comparison of heterosexual and homosexual mating preferences in personal advertisements.

Human observers impact habituated samango monkeys’ perceived landscape of fear (2014)
Journal Article
Nowak, K., le Roux, A., Richards, S., Scheijen, C., & Hill, R. (2014). Human observers impact habituated samango monkeys’ perceived landscape of fear. Behavioral Ecology, 25(5), 1199-1204. https://doi.org/10.1093/beheco/aru110

Humans and human infrastructure are known to alter the relationship between predators and prey, typically by directly or indirectly shielding one of the species from the other. In addition to these overt changes to animals’ behavior, observers may ha... Read More about Human observers impact habituated samango monkeys’ perceived landscape of fear.
