Extended Data Fig. 2: Annual start and end day of the polar bear fasting season in Western Hudson Bay as estimated from PMW and the days-of-year when bears arrive on shore and depart back to the sea ice.
From: Fasting season length sets temporal limits for global polar bear persistence
Days-of-year of observed bear on-shore arrival (triangles) and departure to sea ice (circles) are from ref. 38. The estimated start (magenta) and end (turquoise) dates of the fasting season are the days-of-year corresponding to the squares in Extended Data Fig. 1 with 27 and 3 day offsets to match the timing of the on-shore arrival and departure to sea ice of bears in Western Hudson Bay, respectively.
