Descriptive statistics for hormone data for bottlenose dolphins sampled in Sarasota Bay, FL (2000–2012). Abbreviations: N_i = number of individuals; “% BDL” indicates the percentage of observations with hormone concentrations below respective detection limits.

*Values below detection limit calculated as ½ of the detection limit for the assay (Schwacke et al. 2009)

⁺Detection Limits: cortisol (0.2 μg/dL); aldosterone (11 pg/mL)
