Parameter values from linear mixed effects model analyses of reproductive success (RS) for both the Hamilton and Meese datasets.

The analysis was limited to breeding substrates with at least 5 measurements. P-values (“pMCMC”) were obtained using Markov-chain Monte Carlo sampling using the function pvals.fnc from R library language [32]. Collector identity and year of collection were removed in model simplification and are not reported further. The mean value of reproductive success is given for marsh habitat, and then other rows of the table give the difference from this value for the groups indicated.
