Lemurs in Captivity

Lemurs

What’s next for you? We have quite an exciting new project on elephant matriarchs under way — comparing social knowledge in natural family groups in Kenya, where the matriarch is the oldest in a group of female relatives, with more artificial groups in South Africa formed by translocation in of elephants (often young individuals) from outside. In the longer term we will be examining how age and...

Intertemporal choice in lemurs.

Different species vary in their ability to wait for delayed rewards in intertemporal choice tasks. Models of rate maximization account for part of this variation, but other factors such as social structure and feeding ecology seem to underly some species differences. Though studies have evaluated intertemporal choice in several primate species, including Old World monkeys, New World monkeys, an...

Cognition in ring-tailed lemurs.

In order to better understand the evolution of cognitive abilities in primates, information on cognitive traits of the most basal living primates can provide important comparative baseline data. Compared to haplorhine primates, lemurs have relatively smaller brains and reduced abilities to solve problems in the technical and social domain. However, recent studies have suggested that some cognit...

Captivity selects for smaller eyes

combination of kinetic proofreading and induced fit in tRNA selection provides a suitable balance between fidelity and rapid elongation rates. If we take the simplest case of kinetic proofreading, where there are no differences in forward rate constants introduced by induced fit — where k 3 and k 5 are equivalent for both cognate and near-cognate tRNAs — significant discrimination between cogna...
