Hibernation in Mesocricetus auratus

Journal of Mammalogy, 1958
As a check on laboratory conditions designed primarily for a study of the hibernation of Tamias striatus , hamsters were exposed to cold. Although the hibernation of hamsters has been discussed by Lyman (Jour. Exp. Zool., 109: 55, 1948; Jour. Mamm., 35: 545, 1954), Chatfield and Lyman (Amer. Jour. Physiol., 163: 566, 1950), Kayser (Annee Biol., 29: 109,

Circulating lipids in the golden hamster (Mesocricetus auratus)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974
Abstract 1. 1. Golden hamster normal serum levels of total lipids, free and total cholesterol, phospholipid, free fatty acids and corticosteroids were determined. 2. 2. Circulating lipoproteins were studied in terms of their electrophoretic mobility, metabolic half-life, polyanion agglutination and lipid composition. 3. 3.

The organ of Zuckerkandl of the golden hamster (Mesocricetus auratus)

General and Comparative Endocrinology, 1974
The organ of Zuckerkandl of the hamster involutes during the first 15 post natal days. Its decrease in size can be clearly observed with the glutaraldehyde-silver reaction. A parallel diminution of epinephrine and norepinephrine contained in the organ has been observed.

Hypothermia and behavioural thermoregulation by the hamster (Mesocricetus auratus)

Animal Behaviour, 1970
Abstract Behavioural thermoregulatory temperature preference was investigated prior to and following both mild (approximately 10 °C) and deep (0 °C for 1 hr) hypothermia. Temperature preference of adult male hamsters (Mesocricetus auratus) was assessed with apparatus specifically designed and constructed for that purpose.

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 ...
