...Jussara N. Chaves; Glenn J. Tattersall; Denis V. Andrade ABSTRACT Body temperature regulation under changes in ambient temperature involves adjustments in heat production and heat exchange rates between the animal and the environment. One mechanism involves the modulation of the surface temperature...
