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,

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.

Behavioral Thermoregulation and the Role of Melatonin in a Nocturnal Snake
Hormones and Behavior, 2002Daily and seasonal variations in hormone levels influence the complex interactions between behavior and physiology. Ectothermic animals possess the unique ability behaviorally to adjust body temperature (T(b)) to control physiological rate processes.

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.

Behavioral Thermoregulation with Microwave Radiation of Albino Rats
Perceptual and Motor Skills, 1986The objective of this exploratory study was to investigate the extent to which microwave radiation would reinforce operant behavior in a cold environment. A reversal-design with the single subject serving as its own control was used for testing the reinforcing properties of microwaves. Six albino rats were conditioned to produce 6-sec.

New apparatus for studying behavioral thermoregulation in rats
Physiology & Behavior, 1998The operant system described here contains a box that can be convectively heated or cooled. A rat moves freely in the box. Its location is monitored photoelectrically while its deep body temperature is monitored by a telemetry system. In heat-escape experiments, hot air (40 degrees C) flows through the box.

A system for the study of behavioral thermoregulation of small animals
Physiology & Behavior, 1985A system suitable for the simultaneous monitoring of two unrestrained animals in separate thermoclines is described. It makes use of low-cost, field-proven components to: provide a graded convective and/or conductive temperature continuum over a relatively short runway; measure ambient temperatures at multiple locations within the thermocline; measure ...

Mate Selection and Behavioral Thermoregulation in Fowler's Toads
Science, 1981Male Fowler's toads produce mating calls that are affected by the body size and temperature of the caller. Females are able to discriminate between variations in these calls and select the largest available males. By thermoregulation, males are able to alter their calls to make them more attractive to females.

Relationship between autonomic and behavioral thermoregulation in the mouse
Physiology & Behavior, 1985Preferred ambient temperature (Ta) was measured in nine mice of the BALB/c strain using a temperature gradient. When tested over four consecutive days the mean preferred Ta was 30.9 degrees C. In another study using the same animals, metabolic rate, evaporative water loss, whole-body thermal conductance, and colonic temperature were measured at ...
