Results of mixed-model analyses predicting stress response levels as a function of random (site and year) and fixed effects (individual fish mass and temperature class, above or below 21°C)

Stress response	Model	ΔAIC	Temperature class
HSP70	Site, year, individual mass, 3 day temperature class	8.262	P < 0.001
HSP70	Site, 10 day temperature class	8.849	P < 0.001
Plasma cortisol	Site, 10 day temperature class	2.005	P = 0.010
Plasma glucose	Site, year	4.462	n.a.

Effects retained in the best-supported model (based on differences of at least two AIC units) are listed in the second column.Abbreviations: ΔAIC, change in Akaike information criterion; HSP, heat shock protein; n.a., not applicable.
