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 the frequency of short-distance movements made by acoustic-tagged lake sturgeon in the lower St. Clair River during 2012, 2013, and 2014. Residence time = total days spent in the North and Middle Channels. Release group identifies individuals observed 0–14 days post-surgery and simultaneously-observed conspecifics tagged in prior years. The highest-ranking (best) model is italicized
