Patterns of gammaridean amphipod abundance and species composition associated with dominant subtidal macroalgae from the western Antarctic Peninsula

Assemblages and habitat preferences of soft bottom Antarctic Amphipoda: Admiralty Bay case study

“…Another abundant species in this assemblage is also Prostebbingia gracilis which is a herbivorous species found in high densities on Desmarestia sp. (Huang et al 2006(Huang et al , 2007. The comparison of the present results with data from Jażdżewski et al (1991a) indicates that also areas shallower than 37 m are inhabited by similar amphipod fauna when species richness, diversity and composition are taken into account.…”

“…6). All species contributing most to this assemblage were commonly found in Antarctic shallow sublittoral with Schraderia gracilis, Paramoera hurleyi and Prostebbingia brevicornis reported from coarse sediments where macroalgae were present (Bregazzi 1972a(Bregazzi , b, 1973Arnaud 1974;Thurston 1974;De Broyer 1983;Presler 1986;Jażdżewski et al 1991a, b;Rauschert 1991;Munn et al 1999;Takeuchi and Watanabe 2002;Huang et al 2006Huang et al , 2007. They are considered as herbivorous or herbivorous and detritivorous species.…”

“…However, analysing the species composition of Admiralty Bay assemblage A and the habits of component species reported in the literature (e.g. Thurston 1974;Huang et al 2006Huang et al , 2007 it seems that it is not only the physical conditions which influence the shallow-water assemblage but also the presence of macroalgae, as they do not only provide food but also the shelter for several species (Pabis and Siciński 2010b). Another physically controlled assemblage which can be observed in Admiralty Bay is the one characteristic of Ezcurra Inlet.…”

Chemical Interactions in Antarctic Marine Benthic Ecosystems

“…Avila et al, 2000, Iken et al, 2002. The amphipod Cheirimedon femoratus was chosen as mesograzer consumer in feeding-preference assays because this voracious, omnivorous-scavanger crustacean is found in notably high densities in Antarctica exerting remarkable, localized ecological pressures, often underestimated (Huang et al, 2007).…”

The first report on Amphipoda from Marian Cove, King George Island, Antarctic

“…In the West Antarctic region, studies of invertebrates were conducted mainly in South Shetlands, South Orkneys and Palmer archipelagos (Thurston 1974, Lowry 1975, Siciński et al 2011. Studies of the amphipod fauna are actively pursued, because amphipods represent one of the dominant marine invertebrate groups in the sublittoral zone of the Southern Ocean (Jażdżewski et al 1991, Cattaneo-Vietti et al 2000, Huang et al 2007, Pabis et al 2011, Siciński et al 2011.…”
