ABSTRACT P crit–generally defined as the P O2 below which the animal can no longer
maintain a stable rate of O2 consumption (Ṁ O2), such that Ṁ O2 becomes dependent upon …

Shallow or near-shore environments, such as ponds, estuaries and intertidal zones, are
among the most physiologically challenging of all aquatic settings. Animals inhabiting these …

Human activities are increasing both the frequency of hypoxic episodes and the mean
temperature of aquatic ecosystems, but few studies have considered the possibility that …

Determining the resilience of a species or population to climate change stressors is an
important but difficult task because resilience can be affected both by genetically based …

Early life stages of salmonids are particularly vulnerable to warming and hypoxia, which are
common stressors in hyporheic, gravel bed, rearing habitat (ie a 'redd'). With the progression …

Despite the importance of Atlantic salmon in marine aquaculture production systems,
remarkably little is known about the effects of hydrogen sulfide (H 2 S) on the physiology of …

Oxygen bioavailability is declining in aquatic systems worldwide as a result of climate
change and other anthropogenic stressors. For aquatic organisms, the consequences are …

Hypoxia is one of the most significant threats to biodiversity in aquatic systems. The ability of
high-latitude fish to tolerate hypoxia with histological and physiological responses is mostly …

Many fish encounter hypoxia in their native environment, but the role of mitochondrial
physiology in hypoxia acclimation and hypoxia tolerance is poorly understood. We …

The critical O2 tension (P crit) is the lowest P O2 at which an animal can maintain some
benchmark rate of O2 uptake (Ṁ O2). This P O2 has long served as a comparator of hypoxia …
