Responses were modeled as a function of bear characteristics (age, gender), season (pre-hyperphagia, hyperphagia), and natural food production year (good, poor). Space use responses (log-transformed) were estimated from GPS locational data using a fixed kernel home range methods and include 1) total home range area in km2, ln(Area), 2) amount of home range overlap with human development in km2, ln(HD overlap), and 3) mean human density within the home range, ln(HD density). Activity pattern responses were estimated by fitting a sine curve to the daily mean counts of up-and-down head movements collected by GPS collars and included the number of activity peaks (b) and timing of activity bouts (c) within a 24-hour period.

Indicates 95% CI did not overlap zero.
