Therefore a cold insect cannot escape as quickly from predators as a warm insect, especially if the predator is homeothermic
Handford (1980) provided the earliest report of no association for a homeothermic vertebrate, the rufous-collared sparrow (Zonotrichia capensis).
Interestingly, while decreased variability with increased heterozygosity has since been demonstrated in both poikilothermic and homeothermic vertebrates (e.
In a study of two homeothermic vertebrates, the Fox Sparrow (Passerella iliaca) and Pocket Gopher (Thomomys bottae), Zink et al.
The sum of external forces acting on homeothermic
animal to alter body temperature from the ideal temperature is termed as heat stress (Yousef, 1985).
Thus, when the ambient temperature descends sharply, it may cause a parallel decrease in the body temperature of any homeothermic
(warm-blooded) organism exposed to the change.
Body size and measures of productivity are inversely related among most homeothermic vertebrates (Fenchel 1974).
Conclusions from the literature are not consistent for homeothermic vertebrates.
Plasma cortisol concentrations have been consistently reported to increase in response to starvation or malnutrition in homeothermic
species such as mammals (Costas et al.
For that reason it was suggested that Deinonychus was not endothermic like the birds and mammals of today, but that it was homeothermic
, in other words that it was capable of regulating its body temperature either internally or externally.
The stable and minimal indoor temperature fluctuation in the EPH was beneficial to the pigs as they are homeothermic and have to maintain a relative constant temperature by adjusting their heat production.
The benefit of the ventilation system of the EPH in maintaining homeothermic heat was demonstrated in this study when it recorded a minimal indoor temperature fluctuation range of only 7[degrees]C as shown in Figure 5.
