Temperature and Humidity Relations of the Cockroach

Thermoregulation in Reptiles, a Factor in Evolution

“…body size and shape affect the thermal level of animals heated from below, Herter's findings are one-sided in relation to the preferred (or eccritic, from the Greek, "pick out," as suggested by Gunn and Cosway, 1938, for those who object to the anthropomorphic connotations of "preferred") body temperatures of reptiles. It must be emphasized at this point that the preferred substratum temperature (or V.T.)…”

Thermal preference in Drosophila

“…For example, some insects preferred cooler temperatures when kept in a dry environment prior to testing ( Adesmia clothroata : Deal, 1941; Blatta orientalis : Gunn and Cosway, 1938). However, other authors have found no effect of gradient humidity on T p ( Blatta orientalis : Gunn, 1933; Periplaneta americana : Chapman, 1965).…”

Studies in the biology of Talitridae (Crustacea, Amphipoda): effects of atmospheric humidity

“…Only one specimen was introduced into the chamber at one time, and numerical values of the intensity of reaction to the gradient were based on the respective times spent by the animal in each half of the apparatus. In most of tl,1eprevious work on the behaviour of animals in humidity gradients using an 'alternative' chamber, several specimens have been introduced at once, and measures of intensity of reaction based on readings of the number of animals in each half (Gunn, 1937;Gunn & Cosway, 1938;Pielou & Gunn, 1940;Lees, 1943). This method gives greater uniformity of results, since each result is an average for several specimens, but it cannot be applied to Talitridae because of their high rate of waterloss.…”
