Fig 2. Cortisol Reference Intervals.

Fig 2

(a) Pre-sampling (<30 minutes elapsed time) and (b) post-sampling 95th percentile reference intervals for serum cortisol (μg/dL) versus elapsed sampling time (min). Points represent measured pre-sampling (N = 93) and post-sampling (N = 52) serum cortisol values for bottlenose dolphins sampled in Sarasota Bay, FL 2000–2012; solid lines represent upper and lower bounds for the 95th percentile.
