... responses in SMR and MMR of 35°C-acclimated fish measured at 35°C ( Fig. 2 C,F) are less apparent when examining aerobic scope ( Fig. 3 C). While there remain many questions regarding the utility of the OCLTT hypothesis and the aerobic scope thermal performance curve ( Clark et al., 2013 ; Jutfelt et al...

... Hyperoxia TSR OCLTT Gill allometry Temperature is critical to all biological processes and environmental temperature is especially important to ectotherms, whose body temperature is more or less at its mercy. Understanding what limits upper thermal tolerance for an organism, both in the short...

Published: 29 May 2020
...Emily J. Lombardi; Candice L. Bywater; Craig R. White ABSTRACT The oxygen and capacity-limited thermal tolerance (OCLTT) hypothesis proposes that the thermal tolerance of an animal is shaped by its capacity to deliver oxygen in relation to oxygen demand. Studies testing this hypothesis have largely...

... on acute upper thermal tolerance. Thus, the most parsimonious explanation for our observations seems to be that the central and peripheral nervous systems, and potentially the muscle, have very similar upper thermal limits. The ‘oxygen- and capacity-limited thermal tolerance’ (OCLTT) hypothesis...

... will be impaired through oxygen and capacity limited thermal tolerance [OCLTT; reduced aerobic metabolic scope (MS)] and, on acute exposure to high temperatures, thermal safety margins may be reduced because of constrained acclimation capacity of upper thermal limits.

... ( Pörtner and Farrell, 2008 ). Therefore, the data generated and synthesized in the present study ( Fig. 4 ) represent a relevant entry into the debate about our ability to predict temperature-specific performance and fitness using the OCLTT hypothesis ( Franklin et al., 2009 ; Clark et al., 2013a , b...
