“…While several studies have described epibiosis on cidaroids, recent (e.g. Brey et al 1993, Gutt & Schickan 1998, Massin & Hétérier 2004, David et al 2005a) and fossil (Schneider 2003) analyses of epibiont diversity and specificity remain rare , Hopkins et al 2004). Cidaroids have rarely been taken into account in exploration of epibenthic biodiversity (Ragua-Gil et al 2004).…”

In deep-sea benthic environments, competition for hard substrates is a critical factor in the distribution and diversity of organisms. In this context, the occurrence of biotic substrates in addition to mineral substrates may change the characteristics of sessile fauna. We tested this hypothesis at different localities of the Weddell Sea (Antarctica) by studying the diversity of ectosymbionts living on the spines of cidaroids (echinoids). The presence of cidaroids promoted a higher total specific richness and increased sessile species abundance, but did not change the diversity. Analyses of species distribution suggested that the cidaroids are a favourable habitat for sessile organisms, compared to rocks, but are colonized by relatively specialist sessile species, leaving the unfavourable rock habitat to more generalist species. Therefore, our study highlights the role of some living organisms, such as cidaroids, as key species increasing Antarctic benthic deep-sea species richness through the niche they provide to symbiotic species.

“…One specific impact, however, will be seen on the ectosymbiont fauna of cidaroid spines. In environments where hard substrates are rare, cidaroids are important sources of substrate for sessile organisms such as bivalves, bryozoans, sponges and cnidarians and provide shelter for mobile fauna such as polychaetes, ophiuroids and holothuroids (Brey et al, 1993;Linse et al, 2008;Hétérier et al, 2008). Epibionts of cidaroids are an important source of biodiversity in the Southern Ocean macrofauna (Hétérier et al, 2008;Linse et al, 2008;Cerrano et al, 2009;David et al, 2009), so loss of the urchin host will result in an overall decrease in macrofaunal diversity.…”

Ocean acidification (OA) and the accompanying changes to carbonate concentrations are predicted to have especially negative impacts in the Southern Ocean where, as a result of colder temperatures, there will be shallowing of both the aragonite (ASH) and calcite saturation horizons (CSH). Echinoids are a dominant group of the Antarctic macrofauna which, because of their high-Mg calcite skeleton, are particularly susceptible to changes in the ASH. Using published information on the bathymetric distributions of Antarctic echinoids, we show that the majority of heavily calcified echinoids have their lower bathymetric limit above a depth of ca. 3000 m, approximately the current depth of the CSH. Echinoids whose depth range extends below 3000 m generally have thin, weakly calcified tests and include species from the Order Holasteroida, and the Families Cidaridae and Schizasteridae. Examination of the reproductive mode of Antarctic echinoids shows that brooding, where calcification of the young occurs in the same CaCO 3 environment as the mother, is primarily found at a depth above 3000 m. The predicted shallowing of the ASH and CSH under OA conditions is likely to negatively impact growth and reproduction of heavily calcified brooders in the Family Cidaridae, which may result in changes to bathymetric ranges, local population extinction, and associated losses in macrofaunal biodiversity. As with other calcified deep sea invertebrates, echinoids may be particularly vulnerable to the impacts of increased CO 2 and OA in the Southern Ocean.

“…Clear examples are Laternula elliptica and Adamussium colbecki, which are very abundant in some locations (e.g., Ralph & Maxwell 1977, Arnaud et al 1986, Berkman 1990, Nigro 1993, Cattaneo-Vietti et al 1997, Urban & Mercuri 1998, Passos et al 2005, Kang et al 2009), although they belong to groups with few representatives (Thracioidea and Pectinoidea, with two and three species, respectively). There are also species that occur in highdensity patches, such as Mysella charcoti, Lissarca miliaris, and L. notocardensis (Richardson 1980, Arnaud et al 1986, Brey & Hain 1992, Prezant et al 1992, Brey et al 1993, and other ones that are rich in biomass, e.g., Yoldia eightsi (Peck & Bullough 1993, which is also ecologically important. Other important characteristics of these faunas may be also neglected when comparisons are restricted to the number of species, such as those related to the shells or to the biology of the constituent species.…”

comparative study of the Bivalvia (Mollusca) from the continental shelves of Antarctica and Brazil. Biota Neotrop. 11(1): http://www.biotaneotropica.org.br/v11n1/en/ abstract?article+bn02211012011.Abstract: During identification of bivalve molluscs collected in Antarctica, a rich taxonomic bibliography was gathered, stimulating comparisons with the Brazilian malacofauna. We listed a total of 68 and 368 known shallow-water species (less than 200 m depth) from Antarctica and Brazil, respectively, in order to find species, families and superfamilies in common, and to investigate how these malacofaunas differ in regard to these representative groups and their life habits. There are 23 superfamilies absent in Antarctica, but present in Brazil with at least one species; the reverse does not occur, as all superfamilies known from Antarctica are also recorded from Brazil. The number of Brazilian species is higher, being composed of a mixture of taxa from different biogeographical provinces, whereas in Antarctica there are only a few species adapted to its polar conditions, with minor components from elsewhere. Thus, many typical Caribbean species extend into Brazil, belonging to the diverse Arcoidea, Pectinoidea, Lucinoidea, Cardioidea, Veneroidea, and Tellinoidea. Cemented Ostreoidea, Plicatuloidea, Dimyoidea, Spondylidae (Pectinoidea), and Chamoidea are absent from Antarctica, as are wood (Teredinidae, Pholadoidea) and rock borers (Pholadidae, Pholadoidea; Gastrochaenoidea; and Lithophaginae, Mytiloidea). A large number of Brazilian species of infaunal (e.g., Tellinidae, Veneridae, Cardiidae, and Mactroidea) and epifaunal groups (Pectinidae, Mytilidae, and Arcidae) are absent from or poorly represented in Antarctica. Nuculanoidea, Limopsoidea, Lucinoidea, Galeommatoidea, Cyamioidea, and Cuspidarioidea are the richest groups in Antarctica; some of them are also represented by several species in Brazil, albeit in deeper waters. Three species are recorded as living in both places: Limatula pygmaea (Limidae), Lasaea adansoni (Lasaeidae), and Gaimardia trapesina (Gaimardiidae). Through the analysis of these groups from each fauna, it is possible to identify those that are taxonomically diverse in one place or another, and then emphasize them in ecological studies, eventually using them as model or monitoring organisms. The present paper can be a starting point for future discussion on the existing latitudinal gradients along the coast of eastern South America, stimulating studies on changes occurring in the composition of the faunas of bivalves from Brazil, Uruguay, Argentina, and Antarctica. Resumo: Durante a identificação de moluscos bivalves coletados na Antártica, foi reunida uma rica bibliografia taxonômica, estimulando comparações com a malacofauna do Brasil. Assim, listamos um total de 68 espécies conhecidas para águas rasas (menos de 200 m de profundidade) da Antártica e 368 para o Brasil, procurando encontrar espécies, famílias e superfamílias em comum a ambos os locais, e investigando em que essas malacofaunas di...
