Regulation of body temperature by the bluefin tuna

Comparative Biochemistry and Physiology, 1969
Abstract Bluefin tuna (Thunnus thynnus Linnaeus) can control the temperature of their bodies (25–30°C) so that the warmest portion of the muscle mass varies only 5°C over a 10°C–30°C range of water temperature.

Body temperature regulation in the amphisbaenian Trogonophis wiegmanni

, 2002
We studied the thermal ecology of the amphisbaenian Trogonophis wiegmanni at the Chafarinas Islands (North Africa). We aimed to evaluate the extent of thermoregulation in this fossorial amphisbaenian by analyzing the relationships between environmental ...

Regulation of Body Temperature

1992
Homeothermy is defined by the Thermal Physiology Commission of the International Union of Physiological Sciences [35] as a pattern of temperature regulation in which cyclic variation in core temperature is maintained within arbitrary limits of ±2°C despite much larger variations in ambient temperature.

Body temperature regulation in red-tailed hawks and great horned owls: responses to air temperature and food deprivation

, 1984
-Core body temperatures of Red-tailed Hawks (Buteojamaicensis) and Great Homed Owls (Bubo virginianus) were monitored by telemetry at intervals throughout the winter and summer.

Body temperature and its regulation

Anaesthesia & Intensive Care Medicine, 2005
Abstract Humans must maintain deep-body (core) temperature within narrow limits, despite large fluctuations in ambient temperature and metabolic heat production. Core temperature homeostasis is facilitated by behavioural strategies and physiological effector responses, which influence the factors that add and subtract body heat.

Control of skin blood flow in the neutral zone of human body temperature regulation.

Journal of applied physiology, 1996
In humans, matching of heat loss and heat production in the "neutral" zone, defined operationally in terms of a range of skin temperatures (Tsk), is accomplished by regulation of skin blood flow (SkBF).

Adenosine and the Regulation of Metabolism and Body Temperature

2011
Adenosine levels are increased under conditions of energy deprivation, both because intracellular energy stores are reduced and because ATP is released. The adenosine thus formed can serve to influence energy homeostasis in a number of different ways, besides alterations in blood supply and cellular work (including contraction, maintenance of membrane ...

Body Weight and the Energetics of Temperature Regulation

Journal of Experimental Biology, 1970
ABSTRACT The interactions of basal rate of metabolism, thermal conductance, body temperature, lower limit of thermoneutrality, and body weight in mammals are compatible with Newton’s law of cooling. A small body weight will normally reduce the level and preciseness of body temperature, but a high basal rate of metabolism or a low thermal

Catecholamines and the Regulation of Body Temperature

1980
It is clear now that the two principal components of an animal’s temperature regulating capacity — central and peripheral — utilize catecholaminergic mechanisms. What is biologically so fascinating is the entirely different way in which a given catecholamine acts. On the one hand, central noradrenergic neurons are involved in the complicated activation
