TLDR
A number of general concepts are discussed, for example the relation of convulsions to flight behaviour, the reduction of incoming aggressive stimuli in submissive postures, "Cut-Off", and the inhibition of biting in the more social species.Abstract:
This paper describes elements in the social behaviour of the laboratory rat, mouse, hamster and Guinea-pig. These elements are divided into postures, which are static, and acts, which involve movement. A total of 45 of these elements are mentioned, most of which are common, with only slight modification, to all four species. Apart from these the guinea pig differs in not having a true Upright Posture and also in showing a male sexul display "Rumba". The postures are classified under broad motivational headings. A number of general concepts are discussed, for example the relation of convulsions to flight behaviour, the reduction of incoming aggressive stimuli in submissive postures, "Cut-Off", and the inhibition of biting in the more social species.read more

Changes in social behavior of the male golden hamster accompanying photoperiodic changes in reproduction.
TL;DR: Results suggest that levels of agonistic behavior in the male hamster are inversely related to serum testosterone levels, and scent-marking appears to be unreleated to androgen levels in themale hamster and its role in hamster social behavior remains unclear.

An investigation into the effects of solid or grid cage flooring on the welfare of laboratory rats
TL;DR: Since the rats were observed to spend 70 to 75% of their time resting, it was concluded that their welfare was likely to be improved by housing them on solid floors.

The effect of parachlorophenylalanine on social interaction of male rats
TL;DR: It is concluded that 5‐hydroxytryptamine inhibits sexual behaviour in male rats, and the increase in social interaction seen in juvenile rats may be the behavioural precursor of adult sexual behaviour.

Sexual behavior in continuously cycling rats
TL;DR: The succession of vaginal and behavioral changes was followed throughout the estrous cycle of ten continuously cycling female rats, which took place during proestrus, and found females rejected males on many attempted mounts, although rejection decreased rapidly with rise in frequency of lordosis.

An analysis of the social behaviour of the male laboratory rat
TL;DR: It is suggested that there are two main Flight pathways, one leading to a Submissive Posture and the other to Crouch or Retreat, the occurrence of these is related to two types of behaviour seen in the wild, intra-colonial and territorial.

An analysis of social behaviour in wild rats
TL;DR: A small number of experiments with R. rattus showed that this species possesses all the components of amicable and aggressive behaviour observed in R. norvegicus, but that it is less fierce and more agile.

The Aggressive Behaviour of the Vole
TL;DR: In this article, a laboratory study of the aggressive behaviour of the vole (Microtus agrestis) has been made as part of an investigation of the consequences of CHITTY's hypothesis concerning the cause of vole population cycles.

Rank order in caged rats
E.C. Grant,M.R.A. Chance +1 more
TL;DR: Rank order was found to develop in cages containing 2, 3, 4 and 5 male rats but not in cagescontaining 6 male rats when assessed during the first three weeks after weaning, providing confirmatory evidence that the groups possess a stable structure.
