In cooperative breeding systems, some individuals help to raise offspring that are not their
own. While early explanations for such altruistic behaviour were predominantly based on kin …

The general belief that cooperation and altruism in social groups result primarily from kin
selection has recently been challenged, not least because results from cooperatively …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

The evolution of cooperative breeding has been traditionally attributed to the effect of kin
selection. While there is increasing empirical evidence that direct fitness benefits are …

Anthropogenic (man-made) noise is a global problem and present in virtually all terrestrial
and aquatic environments. To date, most studies investigating the potential impact of this …

Social evolution is tightly linked to dispersal decisions, but the ecological and social factors
selecting for philopatry or dispersal often remain obscure. Elucidating selection mechanisms …

The group augmentation (GA) hypothesis states that if helpers in cooperatively breeding
animals raise the reproductive success of the group, the benefits of living in a resulting …

The conundrum of why subordinate individuals assist dominants at the expense of their own
direct reproduction has received much theoretical and empirical attention over the last 50 …

The behaviour of animals towards their mirror image (“mirror test”) is routinely used as a
proxy to measure aggression levels, especially in fish. The lack of evidence for visual self …

Although kin selection is assumed to underlie the evolution of sociality, many vertebrates—
including nearly half of all cooperatively breeding birds—form groups that also include …
