Geographic variation and thermal plasticity shape salamander metabolic rates under current and future climates
D. J. Munoz, D. A. W. Miller, R. Schilder, Evan H. Campbell Grant
2022, Ecology and Evolution (12)
Predicted changes in global temperature are expected to increase extinction risk for ectotherms, primarily through increased metabolic rates. Higher metabolic rates generate increased maintenance energy costs which are a major component of energy budgets. Organisms often employ plastic or evolutionary (e.g., local adaptation) mechanisms to optimize metabolic rate with respect...
