Figure 1. Longitudinal RMR data collected for four spotted seals (a–d) over a 4-year period. Data from each individual in successive years are stacked and displayed in two adjacent panels. Left panels display monthly mean mass-specific RMR (±SD) for each animal. On average, four data points (range: 1–11) were collected each month. Dashed vertical lines denote the typical molting period. Source data for the left panels, along with corresponding absolute RMR values and subject metadata, are provided as Supplementary Data. Right panels display individual metabolic data points collected during the 100 days preceding and 100 days following the 50% molt date each year (solid vertical line). Dashed vertical lines denote the mean start and end dates of molt referenced to the 50% molt date.
