Supplemental table 1 Competing recapture models generated in the program MARK (model
POPAN) using eastern cottontail rabbit recapture histories obtained in 2010, 2011 and 2012 in
Lincoln Park, Chicago, Illinois. The MLogit link function is used for the probability of entrance
(b; PENT) parameters. Unlike the other model parameters, super-population can exceed 1, and
therefore a Log link function is used for N. Models are arranged in descending order of best fit as
determined by corrected Akaike information criterion (AICc). PENT = probability of entrance.
Var = variance estimation method
