Fig 1. Diel activity of the Gray Fox (Urocyon cinereoargenteus) and Coyote (Canis latrans) with or without human disturbance.

Arrows indicate time (direction) and proportional magnitude (length) of mean activity, and the “net” displays the spread of activity on a 24-h clock, binned at 30-min. intervals. Note the predator’s (the Coyote) nocturnal shift when disturbance was present. The extent of overlap in activity increased from 33% to 45%.
