Data from: Climate warming may affect the optimal timing of reproduction for migratory geese differently in the low and high Arctic

This data is connected to the research paper "Climate warming may affect the optimal timing of reproduction for migratory geese differently in the low and high Arctic". It includes data on timing of snow melt, and timing nest initiation and reproductive success of barnacle geese. Detailed information can be found in the README file.
