The ontogeny of endothermy in birds is associated with disproportionate growth of
thermogenic organs and increased mitochondrial oxidative capacity. However, no similar …

Attaining endothermic homeothermy occurs at different times post-hatching in birds and is
associated with maturation of metabolic and aerobic capacity. Simultaneous measurements …

Developmental rate increases exponentially with increasing temperature in ectothermic
animals, but the biochemical basis underlying this thermal dependence is largely …

It is well established that adult vertebrates acclimatizing to hypoxic environments undergo
mitochondrial remodeling to enhance oxygen delivery, maintain ATP, and limit oxidative …

The effect of hypoxia on cellular metabolism is well documented in adult vertebrates, but
information is entirely lacking for embryonic organisms. The effect of hypoxia on embryonic …

We investigated the ability of juvenile American alligators (Alligator mississippiensis) to
acclimate to temperature with respect to growth rate. We hypothesized that alligators would …

Growth and development can occur over a wide range of physical conditions in reptiles.
Cardiovascular function must be critical to this ability. However, information on …

Oxygen consumption and body temperature were recorded in eider and Long-tailed
ducklings and in barnacle goslings less than 4 days old. In some ducklings organ …

Body size is a central biological parameter affecting most biological processes (especially
energetics) and the mitochondrion is a key organelle controlling metabolism and is also the …

Marsupials lack brown adipose tissue, and therefore rely exclusively on other tissues for
thermogenesis. To determine the magnitude of phenotypic plasticity of the liver in response …
