All animals face the possibility of limitations in food resources that could ultimately lead to
starvation-induced mortality. The primary goal of this review is to characterize the various …

▪ Abstract The ability of animals to survive food deprivation is clearly of considerable survival
value. Unsurprisingly, therefore, all animals exhibit adaptive biochemical and physiological …

The physiological challenges initiated by food limitation and the risk of death by starvation
were likely faced by the very first animals and show no signs of abatement within the …

The postprandial morphological changes of the intestinal epithelium of Burmese pythons
were examined using fasting pythons and at eight time points after feeding. In fasting …

Gut bacteria that produce urease, the enzyme hydrolysing urea, contribute to nitrogen
balance in diverse vertebrates, although the presence of this system of urea-nitrogen …

Anuran estivation is characterized by long episodes of aphagia. To investigate whether
estivating anurans downregulate intestinal performance as an adaptive mechanism to …

Abstract Solute Carrier 15 (SLC15) family, alias H+-coupled oligopeptide cotransporter
family, is a group of membrane transporters known for their role in the cellular uptake of di …

Vertebrate intestinal tracts possess an array of structural and functional adaptations to the
wide diversity of food and feeding habits. In addition to well-described differences in form …

Animals vary widely in their abilities to tolerate extended periods of food limitation. Although
some snakes are known for their unique ability to survive periods of inanition that last up to 2 …

The physiological mechanisms, behavioral adjustments, and ecological associations that
allow animal species to live in extreme environments have evoked the attention of many …
