Figure 4

Cumulative daily activity of black bears and the spawning period of Pacific herring in a 2010, b 2011, and c 2012. Black bear daily activity is the daily sum of independent detections (30 min intervals) of bears by remote cameras positioned on beaches in Quatsino Sound, British Columbia (2010, n = 7 cameras; 2011, n = 11; 2012, n = 11). The study period was March to early May (2010, March 2–May 3, day of the year 61–123; 2011, March 7–May 6, day of the year 66–126; 2012, March 7–April 27, day of the year 67–118). Dashed lines indicate no data (cameras not operational).
