Linear mixed models of fledgling production (yes/no) in relation to (A) age and (B) years before death (YBD).

<p>Summaries were derived from binomial response, linear mixed models (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040413#s2" target="_blank">Methods</a> for details). Variables included in the final models are indicated in bold. The models consisted of 879 breeding attempts by 283 dominant females of all ages. Abbreviations of explanatory variables are explained in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040413#pone-0040413-t001" target="_blank">table 1</a>.
