Aggressive behavior is thought to have evolved as a strategy for gaining access to
resources such as territory, food, and potential mates. Across species, secondary sexual …

Aggression is an adaptive behavior that plays an important role in gaining access to limited
resources. Aggression may occur uncoupled from reproduction, thus offering a valuable …

Various game theory models have been used to explain animal contests. Here we attend to
the presumed cognitive abilities required by these models with respect to information …

Aggression is costly, and animals have evolved tactics to mitigate these costs. Submission
signals are an underappreciated example of such adaptations. Here we review submissive …

Steroids play a crucial role in modulating brain and behavior. While traditionally it is thought
that the brain is a target of sex steroids produced in endocrine glands (eg gonads), the brain …

Communication is inherently social, so signaling systems should evolve with social systems.
The 'social complexity hypothesis' posits that social complexity necessitates communicative …

Aggressive behaviors occurring dissociated from the breeding season encourage the
search of non-gonadal underlying regulatory mechanisms. Brain estrogen has been shown …

Agonistic behavior has shaped sociality across evolution. Though extremely diverse in types
of displays and timing, agonistic encounters always follow the same conserved phases …

Research on intraspecific aggression has typically focused on dominant individuals, but a
better understanding of the consequences and mechanisms of agonistic encounters …

Teleost fishes show an extraordinary diversity of sexual patterns, social structures, and
sociosexual behaviors. Sex steroid hormones are key modulators of social behaviors in …
