Climate change is driving changes in the physical and chemical properties of the ocean that
have consequences for marine ecosystems. Here, we review evidence for the responses of …

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

Climate change and resource exploitation have been shown to modify the importance of
bottom-up and top-down forces in ecosystems. However, the resulting pattern of trophic …

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 …

Abstract Chaput, G. 2012. Overview of the status of Atlantic salmon (Salmo salar) in the
North Atlantic and trends in marine mortality.–ICES Journal of Marine Science, 69: 1538 …

Background Zooplankton play an important role in our oceans, in biogeochemical cycling
and providing a food source for commercially important fish larvae. However, difficulties in …

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 …

Marine zooplankton must deal with seasonal variations of the upper-ocean environment that
are both intense and prolonged compared to their life spans. This leads to large seasonal …

While documentation of climate effects on marine ecosystems has a long history, the
underlying processes have often been elusive. In this paper we review some of the …
