Metabolic theory, life history and the distribution of a terrestrial ectotherm
FUNCTIONAL ECOLOGY | WILEY | Published : 2012
1. Life histories, population dynamics and geographic range limits are fundamentally constrained by the way organisms acquire and allocate energy and matter. Metabolic theories provide general, parameter‐sparse frameworks for understanding these constraints. However, they require the accurate estimation of body temperature which can be especially challenging in terrestrial environments. 2. Here, I integrate a metabolic theory (Dynamic Energy Budget theory, DEB) with a biophysical model for inferring field body temperatures and activity periods of terrestrial ectotherms and apply it to study life‐history variation and geographic range limits in a widespread North American lizard, Sceloporus u..View full abstract
