Fig. 2. Model sensitivity analysis comparing (A) central circulation, (B) muscle,
(C) brain and (D) fat PN2 levels against diving
tissue time constant (
tiss1/2). Results shown are predicted
compartment values at the time the bird reaches the surface after the last
dive in a dive bout (black circles), or after deep (>50 m, red triangles)
or shallow (
50 m, green squares) dives.
