From: Novel species interactions: American black bears respond to Pacific herring spawn
Relationship between mean black bear activity per day and potential predictors during Pacific herring spawn and post-spawn periods. Mean black bear activity for each beach study site and year with a Pacific herring egg mass (kg d.w.), b amphipod (Traskorchestia spp.) mass (kg d.w.), c location, ranked from lowest to highest mean Pacific herring egg mass, and d mean number of gray wolves per day. Mean black bear activity per day represents an average of the cumulative daily number independent bear detections (30 min intervals) by remote cameras positioned on beaches in Quatsino Sound, British Columbia (2010, n = 7 cameras; 2011, n = 11; 2012, n = 11).
