Among vertebrate classes, fishes exhibit by far the greatest variability in competitive and
cooperative behaviors in male reproduction. Scramble competition between reproductive …

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 …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …

Predation risk is a major ecological factor selecting for group living. It is largely ignored,
however, as an evolutionary driver of social complexity and cooperative breeding, which is …

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 …

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 …

The approaches of the social and the biological sciences to the study of behavior have been
seen as almost mutually exclusive. The nature versus nurture debate has been almost …

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 …

Environmental conditions are thought to be responsible for the extent and benefits of
cooperative breeding in many animal societies, but experimental tests are scarce. We …

The 'pay-to-stay hypothesis' proposes that subordinate group members help dominants in
order to be tolerated in the territory. Accordingly, helpers should be punished if they are not …
