North Atlantic Oscillation signatures in aquatic and terrestrial ecosystems—a meta‐analysis
Abstract Climate variations over the Northern Hemisphere are to a substantial proportion associated with the North Atlantic Oscillation (NAO). Recently, many studies revealed the impacts of the NAO on the dynamics of organisms in different ecosystems but the results in the single studies were incons...

Abstract Climate variations over the Northern Hemisphere are to a substantial proportion associated with the North Atlantic Oscillation (NAO).
