The Commentary by Pörtner, Bock and Mark (Pörtner et al., 2017)
elaborates on the oxygen- and capacity-limited thermal tolerance
(OCLTT) hypothesis. Journal of Experimental Biology
Commentaries allow for personal and controversial views, yet
the journal also mandates that ‘opinion and fact must be
clearly distinguishable’ (http://jeb.biologists.org/content/articletypes#
comms). We contend that Pörtner et al. (2017) do not meet
this requirement, and that they present a biased account of the
OCLTT hypothesis. We raise two main points: (1) Pörtner et al.
(2017) do not do justice to the growing number of empirical studies
that failed to support the OCLTT hypothesis when specifically
testing its predictions, and (2) in response to these studies, and
without new empirical evidence to support OCLTT, Pörtner and
colleagues have gradually redefined the core assumptions of the
hypothesis so that it is increasingly difficult to test and has lost
predictive power.
