摘要

For more than a century, biologists have known that body temperature strongly affects the capacities and rates of organisms and thus is a key determinant of organismal performance and Darwinian fitness (1-3). Although rate/temperature (RT) relationships have been quantified for many traits and taxa, interest in RT studies is being revitalized because RT relationships are relevant to predicting biological responses to climate warming (4), as well as to testing the metabolic theory of ecology (MTE), a thermodynamic model of the impacts of body size, temperature, and metabolism on broad-scale biological patterns (5, 6). In PNAS, Dell et al. (7) present a massive compilation of RT data, evaluate quantitative predictions of MTE, and analyze systematic patterns of variation in temperature sensitivity. Their findings both support and challenge MTE, and their analyses will prompt new insights into systematic variation in temperature sensitivity of biological traits.
