Resumo: 	Gros, Ph. (2011). Marine Ecosystems, Chapter 5 in: Current knowledge of impacts of climate change on biodiversity from Metropolitan France – A literature review. Coord. N. Massu &amp; G. Landmann (Ecofor), MEDDTL, 179 pp.  This chapter aims at providing an overview of the current knowledge of impacts of climate change on biodiversity in the marine eco-regions from Metropolitan France (i.e. in the North Sea, English Channel, Celtic Sea, Bay of Biscay and north-western Mediterranean Sea). The major physical (heat budget, circulation) and chemical (acidification) changes in waters of the north-eastern Atlantic and of the western Mediterranean Sea are summarized. Based on results from multidecadal time series analysis and from ongoing research work, examples of observed effects attributable to warming of marine waters are presented. Responses are examined at the different levels of organization of marine biodiversity (eukariotic species are chiefly considered): at the molecular and genetic levels, organism level (physiology, phenology), population level (shift in the geographical distribution of plankton and fish), community level (disruption of between-species relationships), and at the ecosystem level (regime shift). Then are outlined some projections of likely or speculative consequences of future changes in ocean dynamics, in sea-surface temperature, and in water pH. We give special attention to the expected strengthening of stratification of temperate surface waters, and on its quantitative and qualitative effects on plankton primary production and on pelagic food webs. We mention also the capacity of different types of marine ectotherms to maintain their physiological performances in their future marine habitats. A bibliography containing 169 references follows, more than half from the 2008-2010 period.
