Play fighting in juvenile golden hamsters (Mesocricetus auratus): Effects of litter size and analysis of social interaction among males.
Previous studies have shown that different social experiences, such as the interaction involving partners of different ages or among individuals of different sexes, significantly alter the play rate. In the present study, two experiments are described, the hamster being used as subject, to investigate the effects of litter size and to analyse the play fighting behavior among males. It was found...
متن کاملEffects of Social Stimuli on Testosterone, Aggression, and Fighting Behavior in Male Golden Hamsters (Mesocricetus auratus) Honors Thesis

This study examined the influence of testosterone on aggression but also aimed to further explore the effect of previous social stimuli on the outcome of malemale fights. Experimental males were exposed to animal stimuli (males, diestrus females, or estrous females) through a mesh barrier, and th...
متن کاملThe maternal behaviour cycle in golden hamsters (Mesocricetus auratus).
Maternal behaviour in golden hamsters has been the subject of several studies (ROWELL 1960, 1961 a, 1961 b; LOTT 1962; NOIROT & RICHARDS 1966; RICHARDS 1966 a, 1966 b). Most of these have investigated the response to the presentation of pups placed outside the nest by the experimenter, analysing the functional relations between test behaviour and such variables as reproductive stage, hormonal s...
متن کاملNeural Mechanism of Play Fighting – Neural Circuitry, Vasopressin, and CRH – in Juvenile Golden Hamsters
Play fighting is common in juvenile mammals as a peri-pubertal form of agonistic behavior preceding adult aggressive behavior. In golden hamsters, play fighting peaks in early puberty around postnatal day 35 (P-35), and gradually matures into adult aggression in late puberty. Though extensively studied, the neural mechanisms underlying play fighting remains poorly understood. My dissertation fo...
