Gill surface area allometry does not constrain the body mass scaling of maximum oxygen uptake rate in the tidepool sculpin, Oligocottus maculosus

DA Somo, K Chu, JG Richards - Journal of Comparative Physiology B, 2023 - Springer
The gill oxygen limitation hypothesis (GOLH) suggests that hypometric scaling of metabolic
rate in fishes is a consequence of oxygen supply constraints imposed by the mismatched …

Aerobic scope falls to nil at Pcrit and anaerobic ATP production increases below Pcrit in the tidepool sculpin, Oligocottus maculosus

DA Somo, K Chu, JG Richards - Biology Letters, 2022 - royalsocietypublishing.org
The critical oxygen tension of whole-animal oxygen uptake rate, or P crit, has historically
been defined as the oxygen partial pressure (P O2) at which aerobic scope falls to zero and …

Warming-induced “plastic floors” improve hypoxia vulnerability, not aerobic scope, in red drum (Sciaenops ocellatus)

AD Zambie, KL Ackerly, B Negrete Jr… - Science of The Total …, 2024 - Elsevier
Ocean warming is a prevailing threat to marine ectotherms. Recently the “plastic floors,
concrete ceilings” hypothesis was proposed, which suggests that a warmed fish will …

Correcting systematic error in PO2 measurement to improve measures of oxygen supply capacity (α)

AW Timpe, BA Seibel - Comparative Biochemistry and Physiology Part A …, 2024 - Elsevier
An organism's oxygen supply capacity, measured as a ratio of a metabolic rate to its critical
oxygen partial pressure, describes the efficacy of oxygen uptake and transport. This metric is …

An integrative analysis of respiratory capacity, osmoregulatory function, body size, and metabolism in intertidal fishes

DA Somo - 2022 - open.library.ubc.ca
Ocean warming and eutrophication-driven hypoxia are two key threats marine organisms
face with climate change and human activities. The impacts of warming and hypoxia on …
