Table 2. Minimal adequate LMEs with cohort and breeder identity (only in models with repeated measures) as random effects examining the impacts of SSTA during the year before birth and each of the first three years of life on the standardized annual breeding success of booby recruits in the season when they recruiteda and across all their breeding attempts up to age 10 yearsb.
