Table 1. Temporal distribution across undisturbed and disturbed days for seven mammal species in coastal Orange County, California.

All means (from angle θ, with it and 95% confidence intervals, CI, converted to time of day, t, on a 24-h clock) differed significantly (Rayleigh test: P < 0.0001) from a random distribution of occurrences around the clock. Statistic r, which varies from 0 to 1, is a standardized measure of concentration at the mean. At the right, results are presented a rank sum test of temporal shift between undisturbed vs. disturbed occurrences.
