Caribou of the TCH display a variety of movement patterns, including use of four wintering areas. (A) One representative caribou-year of data is depicted for each wintering area. (B-E) Individual paths for the four individuals in panel A are shown divided by season. Teshekpuk Lake, the vicinity of most calving for the TCH, is shown in each panel for reference, with size varying relative to movement distance. (F-I) Corresponding first passage time–net squared displacement (FPT-NSD) plots for caribou overwintering in the (B,F) western coastal plain (W Coastal), (C,G) eastern coastal plain (E Coastal), (D,H) western Brooks Range (W Brooks), and (E,I) eastern Brooks Range (E Brooks). Seasonal periods in panels B-E are replicated along the x-axis of each corresponding FPT-NSD plot, with vertical dashed grey lines indicating season breaks. Panels F-I depict the FPT in the color matching the corresponding movement data in panel A and NSD in grey.
