| Submarine canyons of several regions of the world are preferential conduits for Dense Shelf Water Cascading (DSWC), which quickly modify physical and chemical conditions while transporting large amounts of material towards the adjacent deep margin. Observations conducted during the last 15 yr in the Cap de Creus Canyon (Gulf of Lion, NW Mediterranean Sea) reported several intense events of DSWC. Their effects on the deep-sea biodiversity and ecosystem functioning are almost unknown. To investigate the effects of these episodic events we analysed changes in the meiofaunal biodiversity inside and outside the canyon. Sediment samples were collected at depths varying from ca. 1000 to > 2100 m in May 2004 (before a major event), April 2005 (during a major... |

| Deep-sea ecosystems represent the largest biome of the global biosphere, but knowledge of their biodiversity is still scant. The Mediterranean basin has been proposed as a hot spot of terrestrial and coastal marine biodiversity but has been supposed to be impoverished of deep-sea species richness. We summarized all available information on benthic biodiversity (Prokaryotes, Foraminifera, Meiofauna, Macrofauna, and Megafauna) in different deep-sea ecosystems of the Mediterranean Sea (200 to more than 4,000 m depth), including open slopes, deep basins, canyons, cold seeps, seamounts, deep-water corals and deep-hypersaline anoxic basins and analyzed overall longitudinal and bathymetric patterns. We show that in contrast to what was expected from the sharp... |
