Linear correlations by year between hormone metabolite concentrations (ng.g-1, dried mass) of gray whale fecal samples collected from June to October of 2016–2018 along the Oregon coast, USA: androgen vs progestin metabolites in mature males (A) and resting females (B), and glucocorticoid vs thyroid metabolites in mature males (C) and resting females (D). Asterisks indicate significant correlations between hormone metabolites in specific years. Fecal thyroid metabolite analysis was not performed in 2016. Note logarithmic scale of x- and y-axes.
