Figure 6.

Correlations between blood properties and either the test temperature or the critical thermal maximum (CT_Max). Blood was drawn immediately following the chase to exhaustion (a and b) or immediately after fish lost equilibrium at their CT_Max (c). Significant relationships were identified through a pairwise Spearmen’s correlation analysis (α = 0.05; Fig. S2). Relationships for mean corpuscular haemoglobin concentration (MCHC; a) and blood lactate (b and c) are shown with their corresponding linear model (solid line) and with 95% confidence intervals (dashed line).
