“…West of the Antarctic Peninsula to the Amundsen Sea, warmer circumpolar deep water (>1°C) can flood the deep (>500m) continental shelf accelerating the melting of ice along the West Antarctic Ice Shelf (Jacobs et al, 1996;Lowe and Anderson, 2002;Thorma et al, 2008). These turbulent and complex oceanographic processes increase heterogeneity in a system that may otherwise be considered highly stenothermal and stable (Barnes et al, 2006;Clarke et al, 2009). Small changes in temperature are known to cause drastic changes in metabolic rates of Antarctic benthic invertebrates in shallow water (Peck et al, 2002;Peck et al, 2004) but to date there is no published work on metabolic rates of deep-sea Antarctic invertebrates.…”

“…Plasticity in protobranchs has been observed by changes in morphology over short geographical distances and bathymetry in the Rockall Trough (Fuiman et al, 1999) and can be evidence of distinct ecotypes or even cryptic species; however, sample sizes are often too low for morphological studies to be undertaken. The Antarctic remains an interesting place to study plasticity as much of the benthic environment is considered to be extreme in its thermal stability and highly seasonal pulsed food supply from phytoplankton blooms (Clarke, 1988;Barnes et al, 2006;Clarke et al, 2009). Assessing the extent whereby benthic fauna respond to subtle environmental differences between regions is helpful in the understanding of evolutionary processes that have maintained these populations in the Southern Ocean, and to predict the impacts of future environmental changes (Reed et al, 2012).…”

“…Fishes inhabiting the high-latitude coastal regions of Antarctica, where ice is prevalent and low temperatures occur yearround (7,8), risk accumulating ice within the body. By virtue of their two AFPs, antifreeze glycoprotein (AFGP) (1) and antifreeze potentiating protein (AFPP) (9), members of the perciform suborder, Notothenioidei, thrive in and overwhelmingly dominate these environments (10,11).…”

“…rock surfaces can differ considerably from this and the animals will be affected by zonation ( figure 4C). Few marine invertebrates are capable of colonising the high intertidal zone and surviving there (Waller et al 2006), so N. concinna probably experiences amongst the widest temperature ranges of any marine Antarctic endemic species (Barnes et al 2006). This is true for both subtidal and intertidal N. concinna due to its wide geographic and tidal range (Barnes et al 2006).…”
