Defects in Breathing and Thermoregulation in Mice with Near-Complete Absence of Central Serotonin Neurons
It is concluded that the proper function of the 5-HT system is particularly important under conditions of environmental stress and contributes significantly to the hypercapnic ventilatory response and thermoregulatory cold defense.
Geographical Variation in Bill Size across Bird Species Provides Evidence for Allen’s Rule
The results provide the strongest comparative support yet published for Allen’s rule and demonstrate that thermoregulation has been an important factor in shaping the evolution of bird bills.
Heat Loss May Explain Bill Size Differences between Birds Occupying Different Habitats
This work tested the hypotheses that sparrows can use their bills to dissipate “dry” heat, and that heat loss from the bill is higher in M. m.
Heat Exchange from the Toucan Bill Reveals a Controllable Vascular Thermal Radiator
The results indicate that the toucan's bill is, relative to its size, one of the largest thermal windows in the animal kingdom, rivaling elephants’ ears in its ability to radiate body heat.
Coping with thermal challenges: physiological adaptations to environmental temperatures.
Physiological responses to cold and warmth differ depending on whether animals maintain elevated body temperatures or exhibit minimal internal heat production, whereas ectothermic adaptations to temperature are best exemplified by the numerous mechanisms that allow for the tolerance or avoidance of ice crystal formation at temperatures below 0°C.

Since ranid frogs have minimal tolerance to anoxia, it is untenable to suggest that they spend a significant portion of the winter buried in anoxic mud, but instead utilise a suite of behavioural and physiological mechanisms geared to optimal survival in cold, hypoxic conditions.
Embryonic motility and hatching success of Ambystoma maculatum are influenced by a symbiotic alga
Embryonic motion is potentially vital to salamander development and muscular contractions were more frequent in embryos from algae-inhabited egg masses in light than those in the dark; thus embryos with less O2 reduced muscular activity, thereby reducing energy consumption when O2 availability was compromised.
Hypometabolic homeostasis in overwintering aquatic amphibians.

It is shown that the skeletal muscle of frogs oxyconforms in vitro to the amount of O2 available, and the cellular basis for the oxyconformation of skeletal muscle is unknown, but the hypothesis driving the continuing experiments theories that metabolic suppression at a cellular level is synonymous with suppressed ion leak across cellular membranes is driven.
