Conditioned defeat in the Syrian golden hamster (Mesocricetus auratus)

Behavioral and Neural Biology, 1993
When singly housed under laboratory conditions, male Syrian golden hamsters routinely attack novel conspecific intruders introduced into their home cages. As we report here, after being repeatedly defeated by a larger, more aggressive intruder, such normal territorial aggression on the part of the resident hamsters is replaced by defensive behavior and

Diazepam enhances conditioned defeat in hamsters (Mesocricetus auratus)

Pharmacology Biochemistry and Behavior, 1996
Male hamsters that have been repeatedly defeated by larger, aggressive males subsequently flee from, rather than attack, nonaggressive male intruders that are introduced into their home cages. We have referred to this generalization of flight in response to nonaggressive intruders as "conditioned defeat" (CD).

Discrimination of Salivary Olfactants by Male Mesocricetus Auratus

Psychological Reports, 1984
Salivary secretions of rodents have been observed to play an important role during various developmental periods. The present study examined the nature of adult salivary olfactants in regard to behavioral interactions. The ability of 12 adult male hamsters to detect and respond differentially to salivary stimuli from dominant and submissive males and a

Sexual discrimination by golden hamsters (Mesocricetus auratus)

Behavioral and Neural Biology, 1980
Experiments were designed to investigate variables that may be essential for the establishment of sexual discriminations by male and female golden hamsters. It was demonstrated that heterosexual contact experience of females is not an essential prerequisite for their ability to discriminate between males and females as adults.

Occurrence of hibernation in the golden hamster,Mesocricetus auratus waterhouse

Experientia, 1963
Une hypothese est presentee pour expliquer la variabilite en duree de la periode prelethargique au cours de l'annee. La periode prelethargique pouvait etre approximee a trois mois. Des novembre, le Hamster developpe une predisposition, resultant dans un raccourcissement de la periode prelethargique.

Renal function in the hibernating, and hypothermic hamster Mesocricetus auratus

American Journal of Physiology-Legacy Content, 1975
Plasma and urine concentrations of Na+, K+, and urea were examined in hibernating, hypothermic, and normothermic hamsters. Plasma Na+ and K+ appear unaffected by 48 h of hypothermia (T-re 7 degrees C); however, plasma Na+ increased (P smaller than 0.05) from control values of 125.8 plus or minus 10.2 to 173 plus or minus 9.2 meg/liter in hibernators ...

Histochemical study of glycoconjugates in the epididymis of the hamster (Mesocricetus auratus)

The Histochemical Journal, 1995
The glycoconjugates of hamster epididymis were investigated with conventional and lectin histochemistry. A zone of the caput epididymis, with particular histochemical characteristics, has been differentiated. beta-Elimination in combination with lectins was used to establish the presence and distribution of N- and O-linked glycoconjugates.

Thyroid function and cold acclimation in the hamster, Mesocricetus auratus

American Journal of Physiology-Endocrinology and Metabolism, 1987
Basal metabolic rate (BMR), thyroxine utilization rate (T4U), and triiodothyronine utilization rate (T3U) were measured in cold-acclimated (CA) and room temperature-acclimated (RA) male golden hamsters, Mesocricetus auratus. Hormone utilization rates were calculated via the plasma disappearance technique using 125I-labeled hormones and measuring serum

The Golden Hamster, Mesocricetus auratus

1975
The golden hamster (Mesocricetus auratus) has adapted admirably to life in the laboratory and is now held in esteem by many workers. The majority of known mutant genes produce modification of coat color, but, if the histories of other species are a reliable guide, this aspect will change.

Mesocricetus auratus (Syrian or “golden” hamster)

1967
The karyotypes displayed were prepared from fetal tissue cultures and kindly supplied by Dr. M. Galton, Hanover, New Hampshire. They have been published by Galton & Holt and are reproduced with permission of the publishers. The long arm of X and Y are late replicating as shown by the autoradiographs.
