Modeling Coral Reef Fish Home Range Movements in Dry Tortugas, Florida

Table 2

Estimated home range areas (km²) for empirically observed red grouper, black grouper, and mutton snapper compared to home range areas from simulated detection patterns and actual paths for simulated fish, with difference between simulated and simulated detection home range sizes.
