Fig. 4. Relationship between oxygen consumption, and (A) heart rate and (B) cardiac
output, when Atlantic cod acclimated to 10-11°C were exposed to an acute
temperature increase of 
1.7°C h-1. Open circles represent
data for individual fish; filled circles represent mean values (±
s.e.m.) recorded at particular temperatures. The broken lines define the
linear regressions that were fitted to the individual data (heart rate:
y=2.92x-18.5, r2=0.744; cardiac output:
y=3.55x+16.7, r2=0.759). The solid lines
are third order regressions that were fitted to the mean data to show the
general trends in cardiac parameters with temperature (heart rate:
y=-18.7x+0.4x2+0.0019x3+372.5,
r2=0.986; cardiac output:
y=-20.0x+0.7x2+0.0069x3+242.8,
r2=0.995).
