Endothermy is a conspicuous and important adaptation in birds. Even though juvenile and
adult birds are endothermic and maintain a constant, high body temperature by means of …

Thyroid hormones are key regulators of development and metabolism in vertebrates. During
the nestling period, young of altricial species transition from an ectothermic phenotype to an …

Chickens experience rapid change in their physiology and metabolism during hatching. We
propose that thyroid hormones play a major role in regulating the developmental changes …

The 'membrane pacemaker'hypothesis proposes a biochemical explanation for among-
species variation in resting metabolism, based on the positive correlation between …

For many, if not all, air-breathing vertebrates, breathing-like movements begin while the
embryo is still ensconced in an aqueous environment. This is because primordial regions of …

Compared to mammals, little is known about the development of the respiratory control
system in birds. In the present study, ventilation and metabolism were measured in Coturnix …

Although the mechanistic details of central respiratory chemosensitivity have been studied
for a long time, the emergence of central chemosensitivity in embryos remains largely out of …
