Parental care increases endothermy of striped hamsters (
This study aimed to investigate the role of parental care behavior in sustaining elevated body temperature and to explore the trade-off between metabolic thermogenesis and reproductive output in striped hamsters (Cricetulus barabensis).

Effects of manipulative prolonged temperature increase on the greater ...
We examined the effects of prolonged temperature increases on reproduction, physiology, and behavior adaption in the greater long-tailed hamster using semi-natural enclosures where temperature was manipulated via plastic roofs and windows, creating a greenhouse effect without affecting rainfall.
The Invisible Threat: 5 Insidious Neurobiological Effects of Body Temperature Imbalance Temperature fluctuations or suboptimal thermal conditions in your hamster's environment can have unnoticed but devastating effects on their brain. Understanding these insidious effects is critical to providing them with a better living space.
In the study presented here, RMR was increased through l -tyrosine injections and parental care behavior was measured. This treatment allowed us to test the relationship between RMR level and parental care behavior in a dwarf hamster . It was found that increased RMR enhanced male parental care.
Abstract Temperature affects all biological functions and will therefore modulate ecologically significant interactions between animals and their environment. Here, we examined the effect of ambient temperature (T a) on the thermal biology and energy budget in striped hamsters acclimated to cold (5°C), warm (21°C) and hot temperatures (31°C). Thermoneutral zone (TNZ) was 22.5-32.5°C, 25 ...
Aggressive behaviours track transitions in seasonal phenotypes of ...
These findings suggest that acclimation to the upper-critical temperature of TNZ impairs the hamsters' thermogenic capacity to cope with extreme cold temperature . Reduced ambient temperature was mainly responsible for the leftward shift of TNZ in striped hamsters , which reflects the adaptation to cold environments.
Gene expression profiling during hibernation in the European hamster
This up-regulation of clock genes is most likely associated with arousal from torpor rather than due to a shift in circadian fluctuations , since we previously determined that circadian clockwork stops oscillating in the European hamster SCN during torpor 30 and in most genes we found no apparent, or weak, correlation between the sampling time ...
Last, we assessed the relationship between the estimated weaning mass and adult body mass. This study offers the opportunity to analyze the flexibility and the evolutionary consequences of maternal care dependent on environmental conditions, given a natural annual cycle in temperature and fluctuation in local population density.
