Figure 4 in Chronic stress from fishing gear entanglement is recorded in baleen from a bowhead whale (Balaena mysticetus)

Figure 4. Glucocorticoid hormone profile in baleen from entangled bowhead whale 17B6. Baleen GC concentrations (ng/g) are shown as red circles for cortisol and orange circles for corticosterone. Sample dates were estimated based on an annual baleen growth rate of 17.5 cm/yr, starting with the harvest date (5 May 2017) on the right side of the bottom x-axis and extending retrospectively to approximately November 2005 on the left side of the x-axis (tick marks are months). Sampling locations along the baleen plate are shown on the top x-axis, and background gridlines represent the 1.25 or 2.5 cm sampling intervals used, starting at the plate base.
