Life and death: metabolic rate, membrane composition, and life span of animals.
Maximum life span differences among animal species exceed life span variation achieved by experimental manipulation by orders of magnitude. The differences in the characteristic maximum life span ofExpand

Interactions of corticosterone with feeding, activity and metabolism in passerine birds
Corticosterone (B) may play a direct role in the promotion of feeding behavior under conditions of nutritional stress. However, effects of exogenous B and nutritional stress in passerines indicate aExpand

Dietary n-3 and n-6 fatty acids alter avian metabolism: metabolism and abdominal fat deposition.
The effects of dietary saturated fatty acids and polyunsaturated fatty acids (PUFA) of the n-3 and n-6 series on weight gain, body composition and substrate oxidation were investigated in broilerExpand

ROLES OF THE TENT IN BEHAVIORAL THERMOREGULATION OF EASTERN TENT CATERPILLARS
Eastern tent caterpillars (Malacosoma americanuum) are behavioral thermoregulations and achieve higher body temperatures than expected for ectotherms of similar body size. Construction of a communalExpand

Effects of sublethal fenitrothion ingestion on cholinesterase inhibition, standard metabolism, thermal preference, and prey-capture ability in the Australian central bearded dragon (Pogona vitticeps,
The central bearded dragon (Pogona vitticeps) is a medium-sized lizard that is common in semiarid habitats in Australia and that potentially is at risk of fenitrothion exposure from use of theExpand

Avian Eggs: Thermoregulatory Value of Very High Near-Infrared Reflectance
Studies of the spectral reflectance of the eggs of 25 species of birds from nine families disclosed uniformly high reflectance (often above 90 percent) in the near infrared. This property isExpand
