...Stephen M. Secor SUMMARY Anuran estivation is characterized by long episodes of aphagia. To investigate whether estivating anurans downregulate intestinal performance as an adaptive mechanism to reduce energy expenditure, I compared the metabolic and intestinal responses to feeding, fasting...

...Julian L. Pakay; Andrew A. Hobbs; Scot R. Kimball; Michael Guppy SUMMARY We have investigated the role of eukaryotic initiation factor 2α(eIF2α) in two estivating organisms previously shown to downregulate protein synthesis during metabolic depression, the land snail Helix aspersa Müller...

...BERNARD B. REES; STEVEN C. HAND Within 4 days following entry into estivation, heat dissipation and oxygen consumption by the land snail Oreohelix spp. decreased by 83% compared to standard non-estivating rates. During both non-estivating and estivating conditions, the quantity of heat dissipated...

...STEPHEN P. BROOKS; KENNETH B. STOREY The mechanisms controlling glycolytic rate were examined in foot muscle of the terrestrial snail Otala lactea (Miiller) (Pulmonata, Helicidae), during short and long periods of estivation and anoxia. Binding associations between glycolytic enzymes...
