Asynchrony in the dynamics of chironomids across six locations in northeastern Iceland

The objective of this study was to determine whether chironomid abundances fluctuated synchronously across five subarctic lakes in northeastern Iceland. Specifically, we wished to determine whether chironomid dynamics were more influenced by localized lake-specific drivers or more regional (climatic or dispersal) drivers. This dataset includes 18 years of sample data from the lakes and three years of the same data identified to the species-level.
