Hormones and cooperative behaviours in the Damaraland mole-rat (Fukomys damarensis)
… in cooperative contributions are common within animal societies such as cooperative breeders, where helpers care for offspring which are not their own. Understanding this variation has been a major focus in behavioural ecology and while evidence has shown that individuals are capable to …

Individual variation in cooperative behaviour in meerkats
… a striking yet poorly understood feature of many animal societies, particularly in cooperative breeders where individuals assist in the care of young that are not their own. While previous research on these systems has emphasised the plasticity of helping and how it varies with current …

Mechanisms involved in eusocial evolution in bees
… understand the origin and maintenance of complex animal societies. Identifying the mechanisms involved in transitions from solitary to group living can shed light on the evolutionary processes through which sociality arises. Bees are a valuable group for studying social evolution because the …

Kin and social network structure in two populations of Octodon degus
A growing body of evidence showing that individuals of some species live in non-kin groups suggests kin selection is not required in all species for sociality to evolve. Here I investigate two populations of Octodon degus, a South American rodent which has been shown to form kin and non-kin groups. …

Co-operation and conflict in societies of the ponerine ant genus Pachycondyla
… the occurrence of conflict and co-operation in animal societies. They all depend on the genetic relationships among individuals. Therefore, the study of unrelated, co-operating individuals provides a unique opportunity to critically test predictions based on these evolutionary theories. Using …

Dialect formation in fragmented populations of the endangered North Island kokako (Callaeas wilsoni)
… for our understanding of the evolution of animal societies and our ability to conserve animal populations.

Living apart together
… of a social unit is a defining characteristic of animal social organization. Dispersed social organizations, where members of a social unit spend the main part of their activity period apart, have only recently been distinguished from cohesive social organizations and are still poorly understood …

Sponge Community Structure and Anti-Predator Defenses on Temperate Reefs of the South Atlantic Bight
The interaction between predation and anti-predator defenses of prey is important in shaping community structure in all ecosystems. This study examined the relationship between sponge predation and the distribution of sponge anti-predator defenses on temperate reefs in the South Atlantic Bight. …
