Table 2 Candidate predictor variables investigated for inclusion in tag transmission regression models
From: Methods for assessment of short-term coral reef fish movements within an acoustic array
Predictor | Units | Description |
|---|---|---|
Distance | m | Distance between tag and receiver (range 0 to 895 m) |
Distance squared | m2 | Square of distance |
Tidal phase | categorical | Takes positive value at ‘slack’ tide, negative value at ‘rising/falling’ tide |
Wind speed | km·h-1 | Continuous wind speed data averaged over interval (range 0–20.9 km·h-1); obtained from nearby National Data Buoy Center’s ‘Pulaski Shoal Light’ C-MAN Station |
Solar phase | categorical | Takes positive value during daytime, negative value at night (based on sunrise/sunset times in Tortugas) |
Depth of receiver | categorical | Water depth at receiver location; takes positive value >17 m, negative value <17 m (range 4 to 34 m) |
