Even though since the time of Bert and Viault mammals and birds have been included in high-altitude studies, human physiology has dominated this field, not only by the number of physiological studies conducted but also ...

Measuring peripheral oxygen saturation (SpO2) with pulse oximeters at the point of care is widely established. However, since SpO2 is dependent on ambient atmospheric pressure, the distribution of SpO2 values in populations ...

Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope ...

Being sessile, plants developed adaptive and flexible strategies for nutrient acquisition. Localized deficiency or oversupply of many nutrients induces morphological and physiological adaptations, such as gas exchange, ...

Two decades after its first detection in the retina, nitric oxide (NO) continues to puzzle visual neuroscientists. While its liberation by photoreceptors remains controversial, recent evidence supports three subtypes of ...

Intertidal organisms have evolved physiological mechanisms that enable them to maintain performance and survive during periods of severe environmental stress with temperatures close to their tolerance limits. The level of ...
