“…Such data can be used to derive the spatial distribution of seafloor relief (with derivatives, such as slope and rugosity), together with bottom type and composition (Fonseca et al, 2009). Such information, in terms of bathymetry, seafloor type distribution and geomorphology, is a valuable source of information for: (i) the description of seabed processes and morphology (Hovland, 2003;Finkl et al, 2008;Hernández-Molina et al, 2008); (ii) habitat mapping (Kostylev et al, 2001;Orpin and Kostylev, 2006;Ryan et al, 2007;Wilson et al, 2007;Brown and Blondel, 2009); (iii) the distribution of benthic biodiversity (Baptist et al, 2006;Thrush et al, 2006;Zajac, 2008); (iv) fish species richness (Pittman et al, 2007); (v) the economic importance of species management (Kostylev et al, 2003;Lucieer and Pederson, 2008;Galparsoro et al, 2009); and, subsequently, (vi) the understanding of benthic ecosystems. Recently, such information has been used for: (i) Integrated Coastal Zone Management (ICZM) (Borja et al, 2008b); (ii) the morphological long-term development of dredged material disposal (Cooper et al, 2007;Marsh and Brown, 2009); (iii) the designation and management of marine protected areas (Harris et al, 2008); and (iv) marine spatial planning (Pickrill and Todd, 2003;Campbell and Hewitt, 2006).…”

“…Shallow areas of East Antarctica (<15 m depth) are covered with ice for most of the year, a necessary condition for microphyte growth that initiates a trophic web. This food attracts mobile animals such as S. neumayeri (Thrush et al 2006), which might be partly dependent on this source of food. Our results suggest that further studies in functional ecology might consider the ecological implication of sea ice coverage and sea surface temperature in population dynamics of S. neumayeri.…”

“…Primary production combined with other parameters of sea water (e.g. temperature, sea ice coverage, salinity, oxygen and nitrate concentration) may also be important (Thrush et al 2006, Saiz et al 2008). In the present work, 2 modelling procedures based on presence-only data, Maxent (Phillips et al 2006) and GARP (Stockwell & Peters 1999) were used to model the distribution of echinoid species at the scale of the entire Southern Ocean.…”

Understanding the factors that determine the distribution of taxa at various spatial scales is a crucial challenge in the context of global climate change. This holds particularly true for polar marine biota that are composed of both highly adapted and vulnerable faunas. We analysed the distribution of 2 Antarctic echinoid species, Sterechinus antarcticus and S. neumayeri, at the scale of the entire Southern Ocean using 2 niche modelling procedures. The performance of distribution models was tested with regard to the known ecology of the species. The respective contributions of environmental parameters are discussed along with the putative roles played by biotic interactions and biogeographic processes. Depth was the parameter that contributed most to both distribution models, whereas sea ice coverage and sea surface temperature had significant contributions for S. neumayeri only. Suitability maps of the 2 species were mostly similar, with a few notable differences. The Campbell Plateau and Tasmania were predicted as suitable areas for S. antarcticus only, while S. neumayeri was restricted to the south of the Ant arctic Polar Front. However, numerous sampling data attest that S. antarcticus is absent from the Campbell Plateau and from Tasmania. Different hypotheses are formulated to explain the mismatch between observed and modelled distribution data. They stress the putative roles played by both oceanographic barriers to dispersal (Antarctic Polar Front), biotic factors (species exclusion patterns) and biogeographic processes (ongoing dispersal).KEY WORDS: Habitat suitability map · Sterechinus · Echinoidea · GARP · Maxent · Southern OceanResale or republication not permitted without written consent of the publisher

“…The deposition site of the organic material determines the spatial distribution and composition of Antarctic benthic communities (Orejas et al, 2003;Thrush et al, 2006;Thatje et al, 2008). The redistribution of pelagic production, together with physical factors (e.g., iceberg scouring, anchor ice, resuspension) and the location of polynyas, appear to be the main factors controlling spatial variability in diversity patterns along the western coast of the Ross Sea (Barry et al, 2003;Thrush et al, 2006). As in the Arctic, the transport of reproductive forms by currents is likely an important factor in determining the species composition of the Antarctic shelf benthos.…”

a b s t r a c tWe compare and contrast the ecological impacts of atmospheric and oceanic circulation patterns on polar and sub-polar marine ecosystems. Circulation patterns differ strikingly between the north and south. Meridional circulation in the north provides connections between the sub-Arctic and Arctic despite the presence of encircling continental landmasses, whereas annular circulation patterns in the south tend to isolate Antarctic surface waters from those in the north. These differences influence fundamental aspects of the polar ecosystems from the amount, thickness and duration of sea ice, to the types of organisms, and the ecology of zooplankton, fish, seabirds and marine mammals. Meridional flows in both the North Pacific and the North Atlantic oceans transport heat, nutrients, and plankton northward into the Chukchi Sea, the Barents Sea, and the seas off the west coast of Greenland. In the North Atlantic, the advected heat warms the waters of the southern Barents Sea and, with advected nutrients and plankton, supports immense biomasses of fish, seabirds and marine mammals. On the Pacific side of the Arctic, cold waters flowing northward across the northern Bering and Chukchi seas during winter and spring limit the ability of boreal fish species to take advantage of high seasonal production there. Southward flow of cold Arctic waters into sub-Arctic regions of the North Atlantic occurs mainly through Fram Strait with less through the Barents Sea and the Canadian Archipelago. In the Pacific, the transport of Arctic waters and plankton southward through Bering Strait is minimal.In the Southern Ocean, the Antarctic Circumpolar Current and its associated fronts are barriers to the southward dispersal of plankton and pelagic fishes from sub-Antarctic waters, with the consequent evolution of Antarctic zooplankton and fish species largely occurring in isolation from those to the north. The Antarctic Circumpolar Current also disperses biota throughout the Southern Ocean, and as a result, the biota tends to be similar within a given broad latitudinal band. South of the Southern Boundary of the ACC, there is a large-scale divergence that brings nutrient-rich water to the surface. This divergence, along with more localized upwelling regions and deep vertical convection in winter, generates elevated nutrient levels throughout the Antarctic at the end of austral winter. However, such elevated nutrient levels do not support elevated phytoplankton productivity through the entire Southern Ocean, as iron concentrations are rapidly removed to limiting levels by spring blooms in deep waters.
