“…They form clusters, or 'provinces', with notable examples in the north east Atlantic from the Porcupine Seabight (De Mol et al 2002;Huvenne et al 2005;Wheeler et al 2005), southern Rockall Trough (Akhmetzhanov et al 2003;Kenyon et al 2003) and west Africa (Colman et al 2005). Large deep-water coral accumulations and 'lithoherms' have also been reported in the western Atlantic along the Florida-Hatteras Slope (Stetson 1962;Neumann 1977), and are now the subject of increased research activity (Reed and Ross 2005;Reed et al 2006;Ross and Quattrini 2007).…”

Offshore banks and seamounts sustain diverse megafaunal communities including framework reefs formed by cold-water corals. Few studies have quantified environmental effects on the alpha or beta diversity of these communities. We adopted an interdisciplinary approach that used historical geophysical data to identify topographic highs on Hatton Bank, which were surveyed visually. The resulting photographic data were used to examine relationships between megafaunal communities and macrohabitat, the latter defined into six categories (mud, sand, cobbles, coral rubble, coral framework, rock). The survey stations revealed considerable small-scale variability in macrohabitat from exposed Late Palaeocene lava flows to quiescent muddy habitats and coral-built carbonate mounds. The first reported evidence for coral carbonate mound development in UK waters is presented, which was most pronounced near present day or former sites of topographic change suggesting that local current acceleration favoured coral framework growth and mound initiation.Alpha diversity varied significantly across macrohabitats, but not between rock and coral rubble, or between smaller-grain sized categories of cobbles, sand and mud. Community composition differed between most macrohabitats, and variation in beta diversity across Hatton Bank was largely explained by fine-scale substratum. Certain megafauna were clearly associated with particular macrohabitats, with stylasterid corals notably associated with cobble and rock habitats and coral habitats characterised by a diverse community of suspension-feeders. The visual surveys also produced novel images of deep-water megafauna including a new photographic record of the gorgonian coral Paragorgia arborea, a species not previously reported from Rockall Plateau.Further interdisciplinary studies are needed to interpret beta diversity across these and other environmental gradients on Hatton Bank. It is clear that efforts are also needed to improve our understanding of the genetic connectivity and biogeography of vulnerable deep-water ecosystems and to develop predictive models of their occurrence that can help inform future conservation measures.

“…Biological data on these reefs have been lacking, but recent studies (Messing et al, 1990;Reed et al, 2006;Ross and Quattrini, 2007) indicate that these habitats support rich invertebrate and ichthyofaunal assemblages. The present study shows that a rich hydroid assemblage is found among the SEUS deep-water coral habitats, and that much basic natural history information, such as reproductive timing and modes, still remains to be gleaned from these samples.…”

“…Our data from North Carolina to east-central Florida indicate that deep-water coral habitats on the continental shelf and slope of the SEUS support highly diverse ichthyofaunal and invertebrate L-A. Henry et al / Deep-Sea Research 155 (2008) 788-800 789 assemblages (Ross and Nizinski, 2007;Ross and Quattrini, 2007). Deep-water coral habitats are focal points of biodiversity in the SEUS in part because of the apparent high productivity around reefs and the habitat complexity conferred by the framework-building scleractinian corals L pertusa, Enallopsammia spp., Madrepora oculata and Oculina varicosa (Reed and Ross, 2005;Reed et al, 2006;Ross and Nizinski, 2007).…”

“…Elsewhere in the North Atlantic, hydroids collected from deep-water Lophelia habitats can be very species rich; 27 species from the Norwegian coast (Dons, 1944;Burdon-Jones and Tambs-Lyche, 1960;Mortensen and Fossa, 2006), 31 species from the SW Irish coast (Henry and Roberts, 2007), and 24 species from the Bay of Biscay (Browne, 1907;Le Danois, 1948). These accounts and the growing evidence for rich megafaunal assemblages associated with the deep-water coral habitats off the SEUS (Reed et al, 2006;Ross and Quattrini, 2007) prompted us to examine the hydroid fauna from our collections.…”

“…The aragonite skeleton of the polyps increases habitat complexity both at and above the seafloor (Rogers, 1999). Dead coral polyps provide hard substrate for sessile filter-feeding organisms (López Correa et al, 2004), with the complexity of the reef morphology providing refuge for mobile organisms such as fish (Husebø et al, 2002;Costello et al, 2005;Ross and Quattrini, 2007;Ballion et al, 2012;D'Onghia et al, 2012), shrimp and other crustaceans (Reed et al, 1982;Mortensen et al, 1995;Krieger and Wing., 2002; Roberts et al, 2008;Le Guilloux et al, 2010;D'Onghia et al, 2012). Local hydrodynamic flow may be influenced by coral structure, enhancing or reducing local depositional rates across a reef, or entrapping suspended material in turbidity loops above the reef structure (Mortensen et al, 1995White, 2007;Wagner et al, 2011).…”

Microhabitat and shrimp abundance within a Norwegian cold-water coral ecosystem

et al. 2013

Cold-water coral (CWC) reefs are heterogeneous ecosystems comprising numerous microhabitats. A typical European CWC reef provides various biogenic microhabitats (within, on and surrounding colonies of coral species such as Lophelia pertusa, Paragorgia arborea and Primnoa resedaeformis, or formed by their remains after death). These microhabitats may be surrounded and intermixed with non-biogenic microhabitats (soft sediment, hard ground, gravel/pebbles, steep walls). To date, studies of distribution of sessile fauna across CWC reefs have been more numerous than those investigating mobile fauna distribution. In this study we quantified shrimp densities associated with key CWC microhabitat categories at the Røst Reef, Norway, by analysing image data collected by towed video sled in June 2007. We also investigated shrimp distribution patterns on the local scale (<40 cm) and how these may vary with microhabitat. Shrimp abundances at the Røst Reef were on average an order of magnitude greater in biogenic reef microhabitats than in non-biogenic microhabitats. Greatest shrimp densities were observed in association with live Paragorgia arborea microhabitat (43 shrimp m⁻², SD = 35.5), live Primnoa resedaeformis microhabitat (41.6 shrimp m⁻², SD = 26.1) and live Lophelia pertusa microhabitat (24.4 shrimp m⁻², SD = 18.6). In non-biogenic microhabitat, shrimp densities were <2 shrimp m⁻². CWC reef microhabitats appear to support greater shrimp densities than the surrounding non-biogenic microhabitats at the Røst Reef, at least at the time of survey
