The estimation of energy expenditure is key to resolve ecological questions and conservation strategies. The puma ( Puma concolor (Linnaeus, 1771)) has been the subject of several efforts to measure the daily energy expenditure (DEE). Most of the est

Trehalose is a nonreducing disaccharide that is a primary storage and energy source in prokaryotes, yeasts, fungi, and invertebrates. Vertebrates digest trehalose with the intestinal brush border membrane (BBM) enzyme trehalase. Intestinal trehalase

A simple method for the identification of brush-border membrane α-glucosidases is described. The proteins were first solubilized and separated in a gel under native, non-denaturing, conditions. The gel was then incubated in substrate solutions (malt

Phenotypic flexibility in avian metabolic rates and body composition have been well-studied in high-latitude species, which typically increase basal metabolic rate (BMR) and summit metabolism (Msum) when acclimatized to winter conditions. Patterns of

Vertebrate diets and digestive physiologies vary tremendously. Although the contribution of ecological and behavioral features to such diversity is well documented, the roles and identities of individual intestinal enzymes shaping digestive traits re

Amphibian populations are decreasing worldwide, and pollution is a contributing factor. Polychlorinated biphenyls (PCBs) are a class of persistent organic pollutants known to exert immunotoxicity. To assess impacts of PCBs on frogs, we exposed Lithob

Current life history theory suggests that during times of extreme energetic demand, animals may need to trade off physiological capacity of certain functions to maintain other more important biological functions. This might be especially true during
