The impacts of Paridae pox on reproductive performance of great tits.

Results of model selection for the effects of parental disease status (PDS), lay date (LD), year, and local breeding density (Density) on measures of reproductive performance in great tits: (a) clutch size (CS), (b) the number of young alive at day 15 (NYoung), (c) the number of young fledged (NFledged), (d) whether any young fledged (FledgedY/N), (e) the number of independent young produced (NIndYoung) and (f) whether parents produced any independent young (IndYoungY/N). Estimates of coefficients of the linear predictors (on the link scale, with standard errors, SE) are shown along with the relevant test statistics (z/t) and their significance (P). Statistics for significant terms (P
