Due to the fish-specific genome duplication event (~ 320–350 mya), some genes which
code for serotonin proteins were duplicated in teleosts; this duplication event was preceded …

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

Fish social behavior can be affected by artificial environments, particularly by factors that act
upon species that show aggressive behavior to set social rank hierarchy. Although …

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 …

Serotonin (5-HT) inhibits aggression and modulates aspects of sexual behaviour in many
species, but the mechanisms responsible are not well understood. Here, we exploited the …

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

Scientific research and public debate on the welfare of animals in human custody is
increasing at present. Fish are in this context mentioned with particular attention to the high …

Differences in social status are often mediated by agonistic encounters between
competitors. Robust literature has examined social status-dependent brain gene expression …

The communication behaviors of vocal fish and electric fish are among the vertebrate social
behaviors best understood at the level of neural circuits. Both forms of signaling rely on …

The neuroendocrine control of intraspecific aggression is a matter of current debate.
Although aggression in a reproductive context has been associated with high levels of …
