From: Do Arctic breeding geese track or overtake a green wave during spring migration?

The match between goose arrival time during spring migration and the date that plants reach a specific development stage.
Specific plant development stages are the peak in nutrient biomass (a) and the onset of spring (b). RMSD and the number of observations (n) are indicated for each stopover site (1–4) and the breeding site (5).
