Habitat-Mediated Dive Behavior in Free-Ranging Grey Seals
Figure 4
Frequency of pelagic dives occurring over fine, coarse, and rock substrates during day and night.
Data represent frequency of pelagic dives out of all dives occurring over areas with available substrate data (n = 43,737), calculated for each seal, and averaged across all (n = 8) seals. For example, over fine sediment, approximately 30% of dives were pelagic during the day, while approximately 50% of dives were pelagic during the night. Error bars represent standard errors. Graph also illustrates how with increasing sediment size/habitat complexity, there is a corresponding decrease in the frequency of pelagic dives.
