Table A1. Results of model averaging procedure to predict each of the five life history traits and r. The parameter estimates are the averages from the five best fit reduced models, and the importance is calculated as the sum of the Akaike weights over all of the models in which the parameter of interest appears. Analysis was performed using the “dredge” routine in the R package “MuMIn”.
