WebbInvestigations of thermoreception and thermoregulation in birds indicate that thermosensors exist not only in the skin on the body but also in the skin around the face, the thoracic brood patch (the area used for egg incubation), and the beak. Thermoreceptors also exist in the spinal cord and brainstem (though apparently not in … WebbStudying the origin of avian thermoregulation is complicated by a lack of reliable methods for measuring body temperatures in extinct dinosaurs. Evidence from bone histology and stable isotopes often relies on uncertain assumptions about the relationship between growth rate and body temperature, or the isotopic composition (δ 18 O) of body water.

Webb20 juni 2011 · This specialized form of thermoregulation means that controlling Tb constitutes a large portion of the energy expended by endotherms when environmental temperatures ( Ta) deviate from the thermoneutral zone (TNZ) ( McNab 2002 ). WebbFew environmental factors have a larger influence on animal energetics than temperature, a fact that makes thermoregulation a very important process for survival. In general, endothermic species, i.e., mammals and birds, maintain a constant body temperature (Tb) in fluctuating environmental temperat … http://biology.ucr.edu/people/faculty/Garland/174_PPT_2016_Winter/174-16-Winter_5_19-Jan_Thermoregulation.ppt santa barbara humane society adoption
