The dynamics of meiobenthic community were investigated on sandy sediments of the pilot station of Zoagli (Ligurian Sea) between January 1991 and January 1992. Meiofaunal densities ranged between 447 (April) and 3421 (July) ind./10 cm2. Nematodes were the dominant group comprising on the average 75 % of the total fauna. Harpacticoid copepods were the second most abundant group (from 1.7 to 55.3 %) followed by Turbellaria (on the average 5.5 % of total fauna) and Polychaeta (on average 1.2 % of total fauna). The importance of several environmental parameters (such as total organic matter, grain size and RPD depth) in structuring the meiobenthic community is discussed. |

The responsiveness of benthic biological communities to climatic drivers and shifts makes them powerful indicators of biogeochemical and other environmental change in the oceans. In addition, benthic ecosystems have an economic value and are considered a vital marine resource. However deep-sea faunal dynamics and ecosystem functioning is not well defined. This has placed a higher priority in recent years on developing and sustaining long-term, time-series studies of benthic biodiversity, rate processes, and ecosystem change in deep-sea and extreme habitats. A few key long-term time-series sites exist across the global Ocean. Many of these sites are reviewed in this paper. However, much of the existing research is uncoordinated and the data collected are... |

The deep sea, the largest biome on Earth, has a series of characteristics that make this environment both distinct from other marine and land ecosystems and unique for the entire planet. This review describes these patterns and processes, from geological settings to biological processes, biodiversity and biogeographical patterns. It concludes with a brief discussion of current threats from anthropogenic activities to deep-sea habitats and their fauna. Investigations of deep-sea habitats and their fauna began in the late 19th century. In the intervening years, technological developments and stimulating discoveries have promoted deep-sea research and changed our way of understanding life on the planet. Nevertheless, the deep sea is still mostly unknown and... |

An era of expanding deep-ocean industrialization is before us, with policy makers establishing governance frameworks for sustainable management of deep-sea resources while scientists learn more about the ecological structure and functioning of the largest biome on the planet. Missing from discussion of the stewardship of the deep ocean is ecological restoration. If existing activities in the deep sea continue or are expanded and new deep-ocean industries are developed, there is need to consider what is required to minimize or repair resulting damages to the deep-sea environment. In addition, thought should be given as to how any past damage can be rectified. This paper develops the discourse on deep-sea restoration and offers guidance on planning and... |

Numerous submarine canyons around the world are preferential conduits for episodic dense shelf water cascading (DSWC), which quickly modifies physical and chemical ambient conditions while transporting large amounts of material towards the base of slope and basin. Observations conducted during the last 20 yr in the Lacaze-Duthiers and Cap de Creus canyons (Gulf of Lion, NW Mediterranean Sea) report several intense DSWC events. The effects of DSWC on deep-sea ecosystems 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 > 2100m in May 2004 (before a major event), April 2005 (during a... |

The composition and dynamics of meio- and macrofauna in a subtidal location at Zoagli (Ligurian Sea, Italy) were followed for an annual cycle (from January 1991 to January 1992). Polychaete recruitment occurred during spring and late summerautumn. The increase in density of predatory nematodes (dominated by <i>Oncholaimellus, Viscosia, Mesacanthion </i>and <i>Chromaspirina</i>) and turbellarians corresponded to the collapse of macrobenthos recruits. Such alteration was probably due to predation by turbellarians and predator-nematodes during and immediately after the macrofaunal larval settlement. Differences in predator pressure were observed between spring and autumn. Conversely, no significant impact was observed on bivalves. The... |

The Marine Strategy Framework Directive (MSFD), introduced in June 2008, was adopted to achieve a Good Environmental Status (GES) in the EU's marine waters and to protect resources of socio-economic interest. The MSFD exerts to the marine area over which a Member State exercises jurisdictional rights in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), including the deep-sea waters, seafloor and sub-seafloor of the Exclusive Economic Zones (EEZ). However, currently the MSFD focuses on coastal habitats and the shallow-water seafloor to the detriment of the deeper habitats. Despite the huge dimension of the deep sea (below 200 m of depth) covering more than 65% of the Earth's surface and including >95% of the global biosphere,... |
