Behavioural reaction norms: animal personality meets individual plasticity.
Recent studies in the field of behavioural ecology have revealed intriguing variation in behaviour within single populations. Increasing evidence suggests that individual animals differ in theirExpand

Behavioural syndromes differ predictably between 12 populations of three-spined stickleback.
Animals often differ in suites of correlated behaviours, comparable with how humans differ in personality. Constraints on the architecture of behaviour have been invoked to explain why suchExpand

Helping effort increases with relatedness in bell miners, but ‘unrelated’ helpers of both sexes still provide substantial care
Indirect fitness benefits from kin selection can explain why non-breeding individuals help raise the young of relatives. However, the evolution of helping by non-relatives requires direct fitnessExpand

Begging and digestive responses to differences in long-term and short-term need in nestling pied flycatchers
Offspring begging provides parents with an honest signal of short-term nutritional need (i.e. hunger). However, offspring that have experienced contrasting levels of long-term food intake may begExpand

Predator inspection behaviour in three-spined sticklebacks (Gasterosteus aculeatus): body size, local predation pressure and cooperation
The apparently maladaptive tendency of fish to approach and inspect potential predators has been explained in terms of useful information gathering or as a signal to the predator that it has beenExpand

Monkeys Spontaneously Discriminate Their Unfamiliar Paternal Kin under Natural Conditions Using Facial Cues
Kin recognition can enhance inclusive fitness via nepotism and optimal outbreeding. Mechanisms allowing recognition of patrilineal relatives are of particular interest in species in which femalesExpand

When are vomiting males attractive? Sexual selection on condition-dependent nuptial feeding in Drosophila subobscura
Nuptial gifts are any nutritious items or inedible tokens transferred from the male to the female as a part of courtship or copulation. Although nuptial gift donation has been studied in a variety ofExpand

Cooperative provisioning dynamics: fathers and unrelated helpers show similar responses to manipulations of begging
Cooperative provisioning dynamics between members of a pair in biparental systems has received a lot of attention, both empirically and theoretically. The dynamics of provisioning in cooperativelyExpand

Helping as a signal: does removal of potential audiences alter helper behavior in the bell miner?
Despite many studies on the evolution of cooperative breeding and helping at the nest, relatively few have explored the possibility that helping functions as a signal to gain social advantage withinExpand
