Unformatted text preview: Lecture 11 Lecture 11 Endothermy Endothermy 11 October 2010 11 October 2010 Heat Balance energy in + energy generated = energy out + energy stored Energy in is dominant in ectotherms. Energy generated is dominant in endotherms. The sum total of heat exchange between an organism and its environment determines the body temperature of the organism. Heat Balance Heat Balance S = solar radiation R = thermal radiation to and from substrate L = latent heat of evaporation E = rate of evaporation G = conduction to and from the ground C = convectional exchange with the air M = metabolic heat production s = storage (or loss) of heat S + R + LE + G + C + M + s = 0 S + R + LE + G + C + M + s = 0 Heat Balance Heat Balance S + R + LE + G + C + M + s = 0 S + R + LE + G + C + M + s = 0 (S + (S + R R i ) + M = (G + C + R ) + M = (G + C + R e + LE) + s + LE) + s eat in + heat generated = heat out + heat stored eat in + heat generated = heat out + heat stored Rearrange....
