Table 2 Odds ratios (OR) and 90% confidence intervals (CI) for the top supported model of two-dimensional utilization distribution (UD) overlap, estimated as the proportional area of UD overlap, for wild pigs (Sus scrofa) across time periods (Season-long [nseason = 2; npigs = 14], Month [nmonths = 6; npigs = 18], and Week [nweeks = 26; npigs = 17]) tracked on Savannah River Site, South Carolina, USA during 2014 and 2016. Colons separating covariate names denote interaction terms and asterisks denote 90% CI of odds ratios that did not overlap 1.
