  1. IVs independent variables, df degrees of freedom, AICc Akaike’s information criterion, w Akaike weights, and goodness of fit statistics (scaled deviance, D*, and P value of associated Chi square test) for generalized linear models used to analyze probability of detection of acoustic-tagged lake sturgeon at locations in the North Channel of the lower St. Clair River (≤2 km from release sites, >2 km upstream or downstream from release sites) during 2012, 2013, and 2014. Release group identifies individuals observed 15–29 days post-surgery and simultaneously-observed conspecifics tagged in prior years. The highest-ranking (best) model is italicized
