Life and death: metabolic rate, membrane composition, and life span of animals.
TLDR
The links between metabolic rate andmaximum life span of mammals and birds as well as the linking role of membrane fatty acid composition in determining the maximum life span are reviewed.

Interactions of corticosterone with feeding, activity and metabolism in passerine birds
TLDR
In White-crowned Sparrows, exogenous B substantially reduced overnight metabolic expenditure by reducing the frequency and amplitude of arousal bouts during the night and, possibly, insurance that the individual will retain sufficient resources to seek food the following day.

Dietary n-3 and n-6 fatty acids alter avian metabolism: metabolism and abdominal fat deposition.
TLDR
It is indicated that dietary fatty acid profile influences nutrient partitioning in broiler chickens and lowers plasma concentrations of serum triacylglycerols and cholesterol.

ROLES OF THE TENT IN BEHAVIORAL THERMOREGULATION OF EASTERN TENT CATERPILLARS
TLDR
Operative temperature models were used to evaluate the roles of the tent and of aggregation behaviors in the thermoregulation of tent caterpillars and found that temperatures of a model aggregation on the tent surface were higher than those of a single caterpillar model.

Acyl composition of muscle membranes varies with body size in birds.
TLDR
Allometric variation in the acyl composition of bird muscle phospholipids is similar to that observed in mammals, although birds have fewer n-3 polyunaturates and more n-6 polyunsaturates than do mammalian phospholIPids.

Effects of sublethal fenitrothion ingestion on cholinesterase inhibition, standard metabolism, thermal preference, and prey‐capture ability in the Australian central bearded dragon (Pogona vitticeps,…
TLDR
Plasma total ChE levels remained substantially depressed up to 21 d after dosing in the high‐dose group, making this species a useful long‐term biomonitor of OP exposure in its habitat.

Seasonal and Acute Changes in Adrenocortical Responsiveness in an Arctic-Breeding Bird
TLDR
Birds captured during the storm showed highly significant increases in both the rate of plasma corticosterone increase during capture and the peak postcapture level compared with birds sampled before the storm, which suggests increased activity of the HPA axis in response to severe conditions and is reminiscent of the response to fasting.

From bivalves to birds : oxidative stress and longevity
TLDR
There is a consistent positive correlation between rates of ROS formation and antioxidant levels among most animals examined so far for these traits, and the consensus of these studies is that ROS and antioxidants levels are inversely related to MLSP.

Avian Eggs: Thermoregulatory Value of Very High Near-Infrared Reflectance
TLDR
Studies of the spectral reflectance of the eggs of 25 species of birds disclosed uniformly high reflectance in the near infrared, associated with the presence of the eggshell pigments protoporphyrin and the bilins, which allow coloration for cryptic or other purposes with minimum solar heating.

Seasonal and Geographic Variation of Cold Resistance in House Finches Carpodacus mexicanus
TLDR
Evidence is assembled suggesting that winter acclimatization is primarily metabolic in captive as well as free-living house finches.
