Body temperature is controlled by balancing heat production against heat loss. For lizards, however, thermoregulation is a time-consuming activity that is energetically costly because the energy and time needed for it may compromise the time or energy that otherwise can be. Tolerate small changes in the internal heat of the body managed by maintaining a high metabolic rate and having a complex respiratory and circulatory system Uploaded on Nov 01, 2014 They are thus classified as homeotherms. 1949 Sep;3(3):195-211. doi: 10.1111/j.1558-5646.1949.tb00021.x. learning objectives 2/13/08 distinguish between the thermoregulators classified as endotherms and ectotherms, homeotherms, heterotherms, and poikilotherms describe the adaptive advantage(s) of endothermy discuss the 4 mechanisms utilized by land homeotherms to balance their heat budget discuss the roles of the hypothalamus in vertebrate Humans normally maintain a body temperature at 37C, and maintenance of this relatively high temperature is critical to human survival. Thermoregulation is a mechanism by which mammals maintain body temperature with tightly controlled self-regulation independent of external temperatures. Mammals, for example, must feed to maintain a constant body temperature. Thermoregulation in Mammals, Birds and Reptiles Pictures retrieved from National Geographic - Heat loss mainly through respiration - Legs -> important in thermoregulation - Higher endurance to high temperature - Body temperature generally higher than mammals Importance of legs One of the advantages of thermoregulation in reptiles is that these animals don't need to eat to maintain their temperature, so all the energy they acquire from food is used for growth. Thermoregulation Thermoregulation is a neural process that matches information about the external environment with the appropriate animal response to maintain a more or less stable internal environment relative to external variation ( Nakamura and Morrison, 2008 ). When sweat comes in contact with the skin, a cooling effect occurs as sweat evaporates. Thermoregulation in Heat Heat Loss by Convection ( conduction 35) Effectiveness depends on how rapidly the air (or water) adjacent to the body is exchanged. The hypothalamus, a portion of a brain which plays an important role in regulating body temperature by acting as a thermostat. Regulating homeotherms Conforming poikilotherms Internal state Internal state External state External state 2 Body temperature after 2 hours in 5, 10, 20, 30 35 0C 40 cat If there is a change in temperature, the body responds by reversing the change, returning it to the normal level. running speeds, growth, reproduction and digestion, by exploiting thermal distribution patterns in the environment to attain physiological optimum body temperatures. by ; Thermoregulation in Reptiles and Amphibians When it comes to reptiles and amphibians, keeping cool is easier than keeping warm. Air currents at 4 mph are about twice as effective for cooling air currents at 1 mph.

The rate at which animals consume energy. This concept is so important that control of thermoregulation is often the principal example cited when teaching physiological homeostasis. Thermoregulation Leads to Homeostasis Endotherms- Mammals, birds, some reptiles, and numerous insects. Mammals also change postures, choosing to expose either fur or naked skin depending on their heat needs. But birds and mammals generally maintain a nearly constant temperature in spite of wide variations in the surroundings temperature. It refers to the ability to regulate that body temperature which best serves survival and reproduction, and it encompasses numerous conflicting constraints and selective pressures. When sunlight isn't available some ectotherms burrow under large objects or in warm soil that act as a heat sink. It also is defined asan estimation of the animal's energy needs. Reptiles and insects also like to bask in the sun, exposing through crests and sails as much surface as they are able to. Thermoregulation in Heat Heat Loss by Evaporation (~ 55%) Heat transferred as water is vaporized from respiratory passages and skin surfaces. Introduction The role of the thermal environment has received increased attention due to the current phenomenon of global warming. We suggest that the physiological mechanisms that facilitate thermoregulation transcend phylogenetic boundaries.
