“…We now know of various intermediate larval feeding modes and drifting stages [7,60], but the total number of larval morphotypes known from Antarctic waters is still !250 [15,16]. Increasing records of pelagic larvae in Antarctic waters have frequently been used to challenge this idea [10,[14][15][16]58,59], but even allowing for missing species identification and unknown energetic conditions in most larval records [15,16], the lack of planktonic larvae is striking compared with the benthic diversity of Antarctic waters [61,62].…”

“…The predominance of brooding species in the Antarctic benthos and especially in the peracarid crustaceans was often proposed a key factor for the success of this group in the Southern Ocean (e.g. Picken 1980;White 1984;Pearse et al 1991). At local scale, however, Stanwell-Smith et al (1999) showed that the diversity of marine invertebrate larvae at Signy Island (Antarctica) was similar to that reported by Thorson (1950) from a single non-polar region (Denmark).…”

“…include a reduction in fecundity, increase in egg size and energy per offspring with increasing latitude (Clarke et al 1985;Shilling and Bosch 1994;Fischer and Thatje 2008). Such reproductive patterns seem evident at least in decapod crustaceans, prosobranch molluscs, and echinoderms (Thorson 1936(Thorson , 1950Clarke 1979;Clarke et al 1985;Pearse et al 1991;Thatje et al 2005). However, the mechanisms driving latitudinal patterns in reproduction are far from being fully understood although often related to adaptations to decreasing temperature and more pronounced seasonality towards higher latitudes (Clarke 2003;Pearse and Lockhart 2004;Thatje et al 2005;Fischer and Thatje 2008).…”

Changes in biomass and elemental composition during early ontogeny of the Antarctic isopod crustacean Ceratoserolis trilobitoides

et al. 2008

Changes in biomass and elemental composition (dry mass, DM; carbon, C; hydrogen, H; nitrogen, N) were studied throughout the early ontogeny in the serolid isopod Ceratoserolis trilobitoides from a population off the South Shetland Islands (62°24.35 0 S, 61°23.77 0 W). Specimens of C. trilobitoides were sampled using an Agassiz trawl during the expedition ANT XXIII-8 of RV Polarstern in January 2007. Classification of embryos into six developmental stages followed previous studies. No clear sizedependant fecundity relationship was found in ovigerous C. trilobitoides. Egg volume increased by about 160 and 400% from stage I to IV and stage IV to VI, respectively. DM, C, N, and H continuously decreased throughout the early ontogeny from stage I to VI, but DM showed significant increase on reaching the late-V stage and premanca stages. The C:N ratio remained relatively stable throughout stages I to V, followed by a significant drop from about 6.17 to 5.5 in subsequent stages, indicating depletion of lipid resources of maternal origin. The results coincide with previous studies and indicate a shift from a lipid-based metabolism throughout early embryo stages to a proteinbased metabolism in the late-V and premanca stage, which requires external energy supply. Given the steep increase in DM in the final phase of embryo development (late-V stage to premanca) and the need for external food supply to exert growth, the possibility of external food supply or cannibalism in early offspring of C. trilobitoides is discussed.

“…data). As low temperature slows down oogenesis as well as growth in bivalve molluscs (Giese, 1959;Sastry, 1979;Pearse et al, 1991), it limits population turnover and hence the capacity of the population to withstand commercial extraction. Consequently, careful studies of potentially exploitable populations are the more important in high latitudes in order to prevent rapid overexploitation.…”

Growth, mortality and productivity of the hard clam Eurhomalea exalbida from Ushuaia Bay, Beagle Channel, were investigated. The parameters of the von Bertalanffy growth function were estimated to be H l = 74 mm, K = 0.18 y À 1 , t 0 = 0.15 y. Maximum individual production amounted to 2.74 g shell-free wet mass (SFWM) at 49.5 mm shell height. Animals between 40 mm and 70 mm shell height contributed most to overall population somatic production P of 134 g SFWM m À 2 y À 1 . Mean annual biomass B amounted to 1123 g SFWM m À 2 y À 1 . Annual P/B ratio and mortality rate Z were estimated to be 0.12 y À 1 and 0.14 y À 1 , respectively. Slow growth and low turnover make this population less suitable for sustainable commercial exploitation. D
