Animals rely on their sensory systems to inform them of ecologically relevant environmental
variation. In the Southern Ocean, the thermal environment has remained between− 1.9 and …

Studies in temperate fishes provide evidence that cardiac mitochondrial function and the
capacity to fuel cardiac work contribute to thermal tolerance. Here, we tested the hypothesis …

The effect of increasing ocean water temperature on morpho-functional traits of Antarctic
marine species is under intense attention. In this work, we evaluated the effects of acute heat …

Antarctic notothenioid fishes are highly stenothermal, yet their tolerance for warming is
species-dependent. Because a body of literature points to the loss of cardiac function as …

Antarctic notothenioids have unique adaptations that allow them to thrive in subzero
Antarctic waters. Within the suborder Notothenioidei, species of the family Channichthyidae …

The origin of aerobic life is one of the most fascinating and elusive topics in biology. Multiple
lines of evidence build a compelling case for a central role of oxygen in driving the evolution …

The dynamic interactions between nitric oxide (NO) and myoglobin (Mb) in the
cardiovascular system have received considerable attention. The loss of Mb, the principal …

The rates of all biological processes depend on temperature. Organisms rely on proteins
that convert external temperature into biological signals to determine appropriate …
