... and predators (Taborsky and Limberger, 1981 ; Wong and Balshine, 2011a). These fish also have a clear linear size-based dominance hierarchy, with increasing body size associated with increasing rank (Balshine-Earn et al., 1998). Natural groups regularly experience turnover of group members as helpers join...

... flexibility to the behavioral repertoire. Experience-dependent modification of innate aggressive behavior in flies alters fighting strategies during fights and establishes dominant–subordinate relationships. Dominance hierarchies resulting from agonistic encounters are consolidated to longer-lasting, social...

...Jasmine L. Loveland; Natalie Uy; Karen P. Maruska; Russ E. Carpenter; Russell D. Fernald 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 social dominance hierarchy...

...Ryusuke Ueno; Toshiki Nagayama SUMMARY We characterized the role of chelae during agonistic encounters of the crayfish Procambarus clarkii . Physical asymmetries in body length, body mass and chelae size were directly related to dominance hierarchy formation. More than 80% of winning crayfish had...

... between smaller (crayfish <20 and 20–32 mm in length) and larger crayfish (41–48 and 69–75 mm). Social hierarchy was formed more rapidly in smaller animals. In larger crayfish, dominance hierarchy was developed through a series of fights. One crayfish would retreat from the fight and be deemed...

...Sacha LeBlanc; Stephen Middleton; Kathleen M. Gilmour; Suzanne Currie SUMMARY When faced with limited resources, juvenile salmonid fish form dominance hierarchies that result in social stress for socially subordinate individuals. Social stress, in turn, can have consequences for the ability...

...Cha-Kyong Song; Laurel M. Johnstone; Manfred Schmidt; Charles D. Derby; Donald H. Edwards SUMMARY Olfactory cues are among the sensory inputs that crayfish use in establishing dominance hierarchies. Throughout their lives, new neurons are continuously added into brain cell clusters 9 and 10, which...

...Cha-Kyong Song; Jens Herberholz; Donald H. Edwards SUMMARY Crayfish fight and form a dominance hierarchy characterized by a pattern of repeated agonistic interactions between animals with a consistent outcome of winner and loser. Once a dominance hierarchy is established, dominant animals display...
