“…Previous attempts to explain Antarctic marine community structure are based mainly on present-day patterns in the recolonization of habitats, following physical destruction by ice scouring at a relatively minor scale [4][5][6]. However, we suggest that these patterns cannot be applied to conditions during Cenozoic glaciations.…”

“…In particular, these processes are likely to have been crucial for the survival of sessile filter feeders, such as sponges, which are characteristic of present-day Antarctic benthic communities [2][3][4]36]. High sedimentation rates can have structuring effects on benthic communities, especially on filter feeders [53]; for example, they should particularly select against filter and suspension feeders, such as gorgonians and sponges, which have evolved feeding mechanisms that exploit the supply of only the smallest particles [54].…”

“…During the present interglacial, iceberg scouring or ploughing, caused by an iceberg running aground on the shelf, is the main physical process affecting the benthic communities (see Glossary) in shallow waters on the Antarctic continental shelf [1,2]. Effects of iceberg scouring vary locally and, on a larger geographical scale, intermediate levels of disturbance by icebergs can even enhance benthic diversity on the Antarctic continental shelf [1,3,4]. Enhanced habitat structuring through local disturbance has been frequently used to explain Antarctic species richness and community structure [2].…”

“…components of Arctic communities (Dayton et al, 1994;Gutt, 2001), while echinoderms (e.g. Odontaster and Sterechinus) are hugely important in the Antarctic (Dayton et al, 1969(Dayton et al, , 1994. The relative ease with which the sub-polar species here initiated ice formation, compared to Antarctic species reported in (Denny et al, 2011), suggests one potential barrier to polar spread: even mild anchor ice events would likely remove all of the sub-polar species we tested.…”

Bio-inspired design of ice-retardant devices based on benthic marine invertebrates: the effect of surface texture Growth of ice on surfaces poses a challenge for both organisms and for devices that come into contact with liquids below the freezing point. Resistance of some organisms to ice formation and growth, either in subtidal environments (e.g. Antarctic anchor ice), or in environments with moisture and cold air (e.g. plants, intertidal) begs examination of how this is accomplished. Several factors may be important in promoting or mitigating ice formation.As a start, here we examine the effect of surface texture alone. We tested four candidate surfaces, inspired by hard-shelled marine invertebrates and constructed using a threedimensional printing process. We screened biological and artificial samples for ice formation and accretion in submerged conditions using previous methods, and developed a new test to examine ice formation from surface droplets as might be encountered in environments with moist, cold air. It appears surface texture plays only a small role in delaying the onset of ice formation: a stripe feature (corresponding to patterning found on valves of blue mussels, ABSTRACTGrowth of ice on surfaces poses a challenge for both organisms and for devices that come into contact with liquids below the freezing point.

It appears surface texture plays only a small role in delaying the onset of ice formation: a stripe feature (corresponding to patterning found on valves of blue mussels, Mytilus edulis, or on the spines of the Antarctic sea urchin Sterechinus neumayeri) slowed ice formation an average of 25% compared to a grid feature (corresponding to patterning found on sub-polar butterclams, Saxidomas nuttalli). The geometric dimensions of the features have only a small (∼6%) effect on ice formation. Surface texture affects ice formation, but does not explain by itself the large variation in ice formation and species-specific ice resistance observed in other work. This suggests future examination of other factors, such as material elastic properties and surface coatings, and their interact...
