A description of the ontogeny of mouse agonistic behavior.

Journal of Comparative Psychology, 1998
The development of agonistic behavior was characterized in outbred Swiss CD-1 male Mus domesticus. At weaning (postnatal day [PND] 21), mice were housed either individually or as male pairs. Social encounters were carried out between dyads of initially unfamiliar same-age and same-housing subjects every 3rd day, from PND 23 to 47.

Estrogenic influences on agonistic behavior in teleost fishes

Hormones and Behavior
Teleost fishes show an extraordinary diversity of sexual patterns, social structures, and sociosexual behaviors. Sex steroid hormones are key modulators of social behaviors in teleosts as in other vertebrates and act on sex steroid receptor-containing brain nuclei that form the evolutionarily conserved vertebrate social behavior network (SBN).

Agonistic behavior and neurochemistry in grouped Japanese quail

Comparative Biochemistry and Physiology Part A: Physiology, 1987
Aggressive behavior and whole brain neurochemistry were measured in stable and unstable pairs of male Coturnix coturnix japonica. Aggressive pecking peaked on day 5 of the daily regrouping regime and returned to a basal level on day 14. Aggressive behavior was associated with increased brain norepinephrine (NE), dopamine (DA), and acetylcholinesterase (

Measuring Agonistic Behavior in Zebrafish

2010
Adult zebrafish (Danio rerio) are territorial, show aggressive behavior, and establish dominantsubordinate hierarchies. Here, a protocol for a standard opponent setup is described, which enables the identification, characterization, and quantification of agonistic activities of zebrafish.

Agonistic behavior in wild and inbred Mus musculus

Behavioral Biology, 1976
A factorial arrangement was used to investigate the effects of genotype (wild, BALB/cJ, and C57BL/6J), sex, and location of encounter on agonistic behavior in a paired-encounter situation. One hundred twenty pairs of mice, each pair consisting of one previously isolated and one previously group-housed mouse of the same sex and genotype, were tested on ...

Environment and Agonistic Behavior in Male Telomian Dogs

Psychological Reports, 1978
Scott ( 1 ) suggested that physical environment may influence agonistic behavior through the physiological effects it has upon animals. Thus environments which produce responses similar to anger should have the highest levels of aggression. This preliminary study examined several environmental conditions and their effects on agonistic behavior in a ...

Agonistic behavior: A model, experimental studies, and perspectives

Neuroscience and Behavioral Physiology, 2000
Agonistic (competitive) behavior includes the manifestations of aggression and submissiveness by individuals in conflict situations and is a universal form of behavior found in animals of different species. The sensory contact model allows aggressive and submissive (inhibited, suppressed) types of behavior to be formed in male mice as a result of ...

The evolution of agonistic behavior in amblyopsid fishes

Behavioral Ecology and Sociobiology, 1983
Agonistic behavior observed in the Amblyopsidae was analyzed using Brillouin's diversity index. Agonistic behavior was not observed in Chologaster cornuta. Chologaster agassizi and Ambloypsis spelaea, the least cave adapted subterranean species in each subfamilial lineage, engaged in relatively intense, complex agonistic bouts.
