Fig. 2: Green wave surfing en route for early, mid and late migrants.
From: Migrating mule deer compensate en route for phenological mismatches
Green wave surfing en route was measured as mean days from peak Instantaneous Rate of Green-up (IRG) ± 95% confidence intervals as a function of distance from winter range (solid lines represent loess regressions). Despite being strongly mismatched ahead or behind the green wave when they began their spring migration, early migrants (n = 47 animal-years; purple), mid-migrants (n = 58 animal-years; green), and late migrants (n = 47 animal-years; orange) ended spring migration largely synchronized and closer to peak IRG. Early and late migrants seemingly compensated for being mismatched with the green wave during migration. The horizontal dashed line represents perfect surfing (0 days from peak IRG).
