Effects of Bombesin on Behavioral Thermoregulation in the Bullfrog
Brain, Behavior and Evolution, 1997Bombesin is a member of a class of neuroactive chemicals that have potent thermoregulatory effects in ectothermic and endothermic vertebrate species. Bombesin-like peptides are found in the brains of ectothermic and endothermic vertebrates and have been implicated in the central nervous system modulation of behavioral thermoregulation.

Behavioral thermoregulation in the fasted C57BL/6 mouse
Journal of Thermal Biology, 2021Under relatively cool ambient temperatures and a caloric deficit, mice will undergo daily torpor - a short-term regulated reduction in metabolic rate with a concomitant drop in body temperature. Mice can alternatively achieve metabolic savings by utilizing behavioral changes, such as seeking a warmer environment.

Thyroxine: effect on behavioral thermoregulation in fishes
Canadian Journal of Zoology, 1982Exposure to thyroxine in the ambient water significantly lowered the preferred temperatures of two fish species. Acute exposure to thyroxine at a concentration of 20 μg/L of water lowered the preferred temperature by approximately 2 °C, while chronic exposure to the same concentration for 14 days prior to testing lowered the preferred temperature by ...

Behavioral Thermoregulation in Butterflies
Ecology, 1966Behavioral thermoregulation is well studied in reptiles but has not previously been known to exist in butterflies, where it seems to be widespread and perhaps universal. Like reptiles, butterflies are heliotherms, deriving their heat almost exclusively from the sun. For reception of heat they make much use of their wings. Blood circulates in the wings,

Behavioral thermoregulation and immobilization: Conflicting demands for survival.
Journal of Comparative Psychology, 1991In three studies, core temperatures of immature chicks rose during immobilization induced by simulated predation and fell rapidly when immobilization terminated. Immobilization termination was predicted by proximity of the core temperature to the daily resting core temperature of adult fowl.

Behavioral thermoregulation in lizards: A circadian rhythm
Journal of Experimental Zoology, 1979AbstractBody temperatures of individually housed Sceloporus occidentalis were monitored continuously while the animals moved freely over a thermal gradient during several daily light‐dark cycles and a subsequent period of constant darkness. These self‐selected body temperatures display a distinct daily pattern, a pattern which is maintained (with an ...

Effect of triethyltin on autonomic and behavioral thermoregulation of mice
Toxicology and Applied Pharmacology, 1984The organotin compound, triethyltin (TET), produces toxic effects in a variety of physiological systems. Thermoregulatory control appears to be especially susceptible to TET toxicity, since TET administration has been shown to cause a pronounced hypothermia in rats.

Taurine and Thermoregulation: Behavioral and Cellular Studies
1982According to the generally accepted model of thermoregulation, the temperature of the body is detected by thermosensitive neurons which bring autonomic and behavioral mechanisms into play to counteract any deviation from the optimal state.

Reptile embryos are not capable of behavioral thermoregulation in the egg
Evolution & Development, 2017Reptile embryos have recently been observed moving within the egg in response to temperature, raising the exciting possibility that embryos might behaviorally thermoregulate analogous to adults. However, the conjecture that reptile embryos have ample opportunity and capacity to adaptively control their body temperature warrants further discussion ...

Behavioral thermoregulation in the California Sea Lion
Behavioral Biology, 1974Behavioral thermoregulation in the California sea lion, Zalophus californianus, was studied during the summers of 1970 and 1971 on San Nicolas and San Miguel Islands, California. Zalophus has a series of behavioral responses which correlates with the rate of radiant input.
