Social aggregation is a widespread and important phenomenon among fishes.
Understanding the questions of why and how aggregations form and are subsequently …

Behavioural individuality is thought to be caused by differences in genes and/or
environmental conditions. Therefore, if these sources of variation are removed, individuals …

Teleost fish exhibit extraordinary cognitive skills that are comparable to those of mammals
and birds. Kin recognition based on olfactory and visual imprinting requires neuronal circuits …

Although the majority of studies on mate choice focus on female mate choice, there is
growing recognition of the role of male mate choice too. Male mate choice is tightly linked to …

Behavior, like most other traits, can have a spatial component, and variability of behavior at
the population level is predicted. In this article, we explore male mate choice at this level …

Kin recognition has been widely observed in various taxa. Cannibalism avoidance may be a
strong driver for the evolution of kin recognition, as it may avoid a reduction in inclusive …

Kin selection theory predicts that genetic relatedness between group members can reduce
the asymmetry in resource partitioning between superior and inferior competitors. In social …

Kin recognition plays an important role in social behavior and evolution, but the proximate
mechanisms by which individuals recognize kin remain poorly understood. In many species …

disentangled familiarity and relatedness using a clonal fish.•Aggression increases and …

Predation threat is a major driver of behavior in many prey species. Animals can recognize
their relative risk of predation based on cues in the environment, including visual and/or …
