Parameter estimates from the chosen generalized linear mixed model (model 2) for gray whale fecal glucocorticoid metabolite concentrations using vessel counts from the previous day, sex, month, year, progestin metabolites, androgen metabolites, and body condition (Body Area Index: BAI) as fixed effects and whale identification as random factor.
