Widespread synchrony in phosphorus concentrations in northern lakes linked to winter temperature and summer precipitation
Abstract In recent years, unexplained declines in lake total phosphorus (TP) concentrations have been observed at northern latitudes (> 42°N latitude) where most of the world's lakes are found. We compiled data from 389 lakes in Fennoscandia and eastern North America to investigate the effec...
