Lecture 29. THERMOREGULATION Summary. Multicellular animals frequently regulate the conditions of their internal environment within rather narrow limits so that individual cells see minimal changes in their environment. This lecture focuses on factors that influence heat exchange, particularly ambient temperature, metabolic rate, radiation, conduction, convection, and evaporation. We will emphasize animals at the warm end of their temperature range and save discussion of adaptive strategies at the cold end of the thermal range for the last lecture of the semester. At the warm end, we will discuss how different types of animals respond to temperature change, why they regulate temperature as much as they are able, and how they balance heat exchange with the environment. Reading Assignment Campbell, N. A. and Reece, J. B. (2008), 8 th edition., Chapter 40, pages 860-874. . Objectives and Questions 1. To be able to explain the difference control of body temperature between an endotherm such as a mammal, and an ectotherm such as a lizard. 2.
