Costs and Consequences of Evolutionary Temperature Adaptation: Response pt. 3

Clarke then shifts his focus to the ecological constraints of temperature, energetics, and life history. The cost of living for marine organisms in low temperatures is significantly lower than those in warmer tropic temperatures. Based on this, Clarke argues that a temperature related latitudinal variation in resting metabolic rates will lead to higher ecological growth in organisms at lower temperatures. Despite this, there is little data that show a connection between energy flow and food-web structures. He fights for a larger concentration on the implications of macroecological variations in energetics of organisms on food-web dynamics. Linking physiology with macroecology is difficult due to the varied findings in studies. We lack an understanding for how thermal physiology and climate determine biogeography
