Thermal tolerances of a large number of terrestrial ectotherm, endotherm and plant species worldwide are analysed, and it is shown that tolerance to heat is largely conserved across lineages, while tolerance to cold varies between and within species.
Trade‐Offs in Thermal Adaptation: The Need for a Molecular to Ecological Integration*
This effort illustrates the need for an overarching concept of thermal adaptation that encompasses molecular, organellar, cellular, and whole‐organism information as well as the mechanistic links between fitness, ecological success, and organismal physiology.

The hypothesis that variation in environmental factors leads to variation in the selective regime for metabolic rates of rodents is supported and a highly significant positive correlation between residual BMR and MMR is indicated, consistent with a key assumption of the aerobic capacity model for the evolution of vertebrates.
Physiological Correlates of Geographic Range in Animals
It is suggested that it may be necessary to evaluate patterns of physiological diversity as a function of different ecological regions oriented to produce mechanisti... to integrate the understanding of the interaction between physiology and distribution within current global warming scenarios.
Intrapopulational variation in the standard metabolic rate of insects: repeatability, thermal dependence and sensitivity (Q10) of oxygen consumption in a cricket
The results suggest that MR could be of selective value in insects, showing consistency over time and intrapopulational variability in its thermal dependence, Nevertheless, its heritability remains to be determined.
Daily and seasonal limits of time and temperature to activity of degus
Presentamos un analisis de la flexibilidad conductual en la actividad diaria del degu (Octodon degus), un roedor caviomorfo, en respuesta a la heterogeneidad del ambiente temporal (diario y…
Effects of sugar concentration on hummingbird feeding and energy use
Passerines versus nonpasserines: so far, no statistical differences in the scaling of avian energetics.
We analyzed and compared the scaling of both basal and maximal thermogenic metabolic rates in passerine and nonpasserine birds using conventional and phylogenetic methods. In spite of the presumed…
Energetics and torpor of a South American “living fossil”, the microbiotheriid Dromiciops gliroides

Torpor in this species as well as in marsupials in general appears to be an opportunistic response to unpredictable biotic and abiotic conditions.
Dietary Flexibility and Intestinal Plasticity in Birds: A Field and Laboratory Study
Doubts are cast on the notion that dietary flexibility and the plasticity of the gut's enzymes are necessarily correlated and on the general validity of the adaptive modulation hypothesis after the first field documentation of modulation of intestinal enzymes by diet in birds.
