Abstract Characterization of species diversity of zooplankton is key to understanding,
assessing, and predicting the function and future of pelagic ecosystems throughout the …

This paper focuses on the ecosystem regime shift in the North Sea that occurred during the
period 1982–1988. The evidence for the change is seen from individual species to key …

Summary 1 Climate change impacts have been observed on individual species and species
subsets; however, it remains to be seen whether there are systematic, coherent assemblage …

Much speculation and some evidence suggest that jellyfish and ctenophore populations
have increased in recent decades. Unfortunately, few past records exist with which to …

Predicted impacts of climate change on the marine environment include an increase in
temperature, a rise in sea levels and a decrease in sea-ice cover. These impacts will occur …

The index of the North Atlantic Oscillation, the dominant mode of climatic variability in the
North Atlantic region, changed in the late 1980s (1987–1989) from a negative to a positive …

From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

A current critical issue in climate change studies is how temperature changes and shifts on
different spatial and temporal scales can affect organisms in terms of trends, variability and …

Data obtained since 1958 from the continuous plankton recorder show an increasing
occurrence of jellyfish in the central North Sea that is positively related to the North Atlantic …

We combine the temperature and phytoplankton data from one of the longest aquatic data
sets in history, the Helgoland Roads (North Sea, 54° 11.3'N, 7° 54.0'E) timeseries to …
