The best-fit model was selected using both statistical criteria ( R 2 and AIC) and the model's prediction of three anchor points for hypoxic performance: critical P O 2 ( P crit ), maximum Ṁ O 2 and a new metric, the minimum P O 2 that supports 50% of absolute aerobic scope ( P AAS-50...

We propose that the behavioural differences between these two sympatric morphs are functionally complementary and represent evolutionary stable...

Rather than an index of hypoxia tolerance, P crit is a reflection of α, which evolves to support maximum energy demands and aerobic scope at the prevailing temperature and oxygen level. Thus, direct determination of α has several advantages...
