Patterns of daily torpor and day-roost selection by male and female big brown bats (Eptesicus fuscus)
Daily torpor can provide significant energy savings, but in bats may reduce rates of fetal and juvenile development and spermatogenesis. We examined the use of torpor during the day by male andExpand

Size differences within a dominance hierarchy influence conflict and help in a cooperatively breeding cichlid
In size-structured groups, conflict over rank, resources or access to breeding opportunities is expected to be greatest among individuals that are similar in size. We tested this general predictionExpand

The relationship between social status, behaviour, growth and steroids in male helpers and breeders of a cooperatively breeding cichlid
We tested whether subordinate helper males of the Lake Tanganyika cooperatively breeding cichlid Neolamprologus pulcher show elevated excretion levels of the stress hormone cortisol and reducedExpand

Validation of a randomization procedure to assess animal habitat preferences: microhabitat use of tiger sharks in a seagrass ecosystem.
1. Tiger sharks Galeocerdo cuvier are important predators in a variety of nearshore communities, including the seagrass ecosystem of Shark Bay, Western Australia. Because tiger sharks are known toExpand

The effects of temporal variation in predation risk on anti-predator behaviour: an empirical test using marine snails
Foraging animals must often balance the conflicting demands of finding food and avoiding predators. Temporal variation in predation risk is expected to influence how animals allocate time to theseExpand

Mobile Pastoralists in the Logone Floodplain Distribute Themselves in an Ideal Free Distribution
We examined whether mobile pastoralists in the Logone floodplain of Cameroon distribute themselves according to the ideal free distribution (IFD), which predicts that the number of individuals inExpand
