Selection for agonistic behavior in wild female mice

Behavior Genetics, 1980
This article reports the results of 11 generations of selective breeding for isolation-induced, interfemale aggression in Mus musculus. Within-family selection was used to form two high, two low, and two unselected control lines, beginning with a population of wild-trapped mice.

Agonistic Behavior in Freshwater Crayfish

2007
AbstractFighting success and dominance in crayfish depends on a variety of extrinsic and intrinsic factors. Most intrinsic factors studied to date are related to the physical size of the crayfish. Larger crayfish or those with larger chelae often have advantages in agonistic interactions.

Pheromonal Influences on Rodent Agonistic Behavior

1977
The effects of odors on rodent agonistic behavior were unnoticed for many years. Attention was focused instead on examining the role of hormones in the regulation of attack and defensive responses. The impetus for study of the area was provided by Beeman’s (1947) discovery that androgen injections restored intraspecific sparring in castrated male ...

Parallel changes in agonistic and non-agonistic behaviors during dominance hierarchy formation in crayfish

Journal of Comparative Physiology A, 2003
Agonistic and non-agonistic behaviors were studied before, during, and after the formation of social status in crayfish. Differences in the expression of a non-agonistic behavior by dominant and subordinate crayfish developed in parallel with the differences in agonistic behaviors that indicate the animals' social status.

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 (

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 ...

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 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 ...
