Q₁₀as a Function of Size and Habitat Temperature in Poikilotherms

Abstract

Data has been assembled from various sources, which show that Q10 of various measures of activity commonly increases with increasing size within the physiologically normal ranges of temperature. Several instances are drawn together, which indicate that the Q10 of a given species varies with the habitat temperature to which it is adapted. Neither relation as presently formulated can be said to be necessarily adaptive and exceptions to both are pointed out.
