The detailed paths of a male and female model crab over their entire
lifetime show that they move in a quasi-continuous manner
(Fig. B11). As a result of the dependence
of movement rate on temperature, the median and range of velocities of
crab movement increased during summer, peaking in July at a median of
m/hr - within the range reported in
Appendix A.5.4. Crabs also responded quickly
to changes in the location of low DO
(Fig. B12) resulting in high
crab densities on the edges of hypoxic regions and almost no crab
biomass in low DO areas.
