Therefore a cold insect cannot escape as quickly from predators as a warm insect, especially if the predator is homeothermic
. Insects that are cold are therefore at higher risk and should be more likely to group in order to avoid predators.
"It just says that the brain is not as homeothermic
as we think."
animals develop adaptive modifications to cope with Ta fluctuations that include adjustments in metabolism, insulation, and behavior .
Briefly, rats were anesthetized with 60 mg/kg (intraperitoneally) pentobarbital sodium and kept on homeothermic
pad to maintain body temperature at 37[degrees] C.
Broiler chickens are homeothermic
animals with internal temperature around 41.5[degrees]C with a body covered with feathers, which favors thermal insulation but makes difficult heat exchange with the environment.
The hierarchical relevance of the central nervous system (CNS) to thermal control activities is explained by fine adjustments of maximum enzyme reaction activities to a given temperature in homeothermic
CALDER, W.A Scaling of physiological processes in homeothermic
Throughout the experiment, the body temperature was monitored and maintained at 36.5 [degrees]C-37.5 [degrees]C with a homeothermic
blanket system (FHC, Brunswick, ME, USA).
The only mammal present that is not naturally homeothermic
is Grant's small golden mole (Eremitalpa granti), which swims through the sand of the Namib dunes in search of its invertebrate prey like a fish in water.
In addition, their low thermal inertia dictates that small birds must respond rapidly to changes in the thermal environment if they are to remain homeothermic
. No previous study has examined the interaction between convective and radiative heat transfer and their combined effects on metabolic heat production in intact animals.
Handford (1980) provided the earliest report of no association for a homeothermic
vertebrate, the rufous-collared sparrow (Zonotrichia capensis).
Average core body temperature of cattle is well-known as 38.5[degrees]C [+ or -] 0.50[degrees]C and even 1 or 2 degree of body temperature loss from normal state may be considered as hypothermia in homeothermic
animal (Carroll et al., 2012).
