Swimming speed and allocation of time during the dive cycle in Antarctic fur seals
Article Abstract:
Antarctic fur seals adopt various foraging tactics based on the position of their prey in the water column. These tactics are perhaps guided by their ability to dive aerobically. During shallow diving the animals are generally optimizing their energetic efficiency, while diving deeper they maximize their total energy intake. To study the behavior of the Antarctic fur seals during sustained bouts of diving, the swimming speed and time allotted to various parts of the dive cycle has been measured in 10 adult female Antarctic fur seals, Arctocephalus gazella.

Behavioural patterns associated with faecal cortisol levels in free-ranging female ring-tailed lemurs, Lemur catta
Article Abstract:
Research among free-ranging female ring-tailed lemurs has confirmed the hypothesis that predation threat, social status and decreased food accessibility can be significant challenges to free-ranging animals. Reproductive status and dominance indices were shown to be significant predictors of faecal cortisol variability in the ring-tailed lemurs. The research produced strong support for the prediction that cortisol levels would be linked to dominance status.

Finescale topographical correlates of behavioural investment in offspring by female grey seals, Halichoerus grypus
Article Abstract:
Topographical influences on the behavior of breeding female grey seals were examined using submetre resolution digital terrain models of two sites in a rocky breeding colony. Females preferred to breed close to water, making frequent forays between pups and water. Topographically induced behavior differences may affect the quantity and quality of pup provisioning by the mother.
