What is torpor in biology These data provide evidence that torpor bouts are induced by Mar 4, 2013 ยท Hibernation (multiday torpor) and daily torpor in heterothermic mammals and birds are characterized by pronounced temporal reductions in body temperature, energy expenditure, water loss, and other physiological functions and are the most effective means for energy conservation available to endotherms. This temporary period of inactivity is called torpor, and reserves energy in especially harsh conditions. e. It is characterized by cycles of metabolic suppression, known as torpor, accompanied by a controlled decrease in body temperature, heart rate, breathing rate, and a general halt of the cell cycle 2. It has been used to describe those plants, insects and fish that warm specific tissues for limited periods of time, but it has mostly been used to describe mammals and birds that allow extremities to cool in order to retain heat (regional heterothermy), or which go into torpor and hibernation (temporal Torpor, in the context of biology, refers to the process of hibernation. In general, there are two main forms of developmental arrest: diapause and quiescence (or torpor). This state is typically shorter and less profound than hibernation, which involves extended periods of inactivity. Wild D. If both are "warm-blooded," then why are birds not considered mammals?, What is the limiting factor in how large land animals can become?, Which of the following best explains how some animals survive even in times of True or False? Given unlimited food, shrews should enter torpor on cold nights.
