    Fatty acid content of POM, sediment, foraminifer and peracarid samples obtained during POLARSTERN cruise ANT-XXIV/2 (PS71) (2011)
    PANGAEA
    In:  Supplement to: Würzberg, Laura; Peters, Janna; Brandt, Angelika (2011): Fatty acid patterns of Southern Ocean shelf and deep sea peracarid crustaceans and a possible food source, foraminiferans.

    Beschreibung: In order to investigate the diversity of diet composition in macrobenthic peracarid crustaceans from the Antarctic shelf and deep sea, the fatty acid (FA) composition of different species belonging to the orders Isopoda, Amphipoda, Cumacea and Tanaidacea was analysed. Multivariate analyses of the FA composition confirmed general differences between the orders, but also distinct differences within these orders. To gain information on the origin of the FAs found, the potential food sources sediment, POM and foraminiferans were included in the study. Most of the analysed amphipod species displayed high 18:1(n-9)-18:1(n-7) ratios, widely used as an indicator for a carnivorous component in the diet. Cumaceans were characterised by increased phytoplankton FA markers such as 20:5(n-3) (up to 29% of total FAs), suggesting a diet based on phytodetritus. High values of the FA 20:4(n-6) were found in some munnopsid isopods (up to 21% of total FAs) and some tanaidacean species (up to 19% of total FAs). 20:4(n-6) also occurred in high proportions in some foraminiferan samples (up to 21% of total fatty acids), but not in sediment and POM, possibly indicating the ingestion of foraminiferans by some peracarid crustaceans.

    Gut filling, gut content and fatty acid composition of demersal fish species sampled during POLARSTERN cruise ANT-XXIV/2 (2011)
    PANGAEA
    In:  Supplement to: Würzberg, Laura; Peters, Janna; Flores, Hauke; Brandt, Angelika (2011): Demersal fishes from the Antarctic shelf and deep sea: A diet study based on fatty acid patterns and gut content analyses.

    Beschreibung: The gut contents and fatty acid composition of 49 fish belonging to five Antarctic demersal families (Nototheniidae, Macrouridae, Channichtyidae, Bathydraconidae and Artedidraconidae) sampled at two stations at the Southern Ocean shelf and deep sea (600 and 2150 m) were analysed in order to identify their main food resource by linking trophic biomarkers with the dietary items found in the fish guts. Main food items of most fish analysed were amphipod crustaceans (e.g. in 63% of Trematomus bernachii guts) and polychaetes (e.g. in 80% of Bathydraco sp. guts), but other food items including fish, other crustaceans and gastropods were also ingested. The most prominent fatty acids found were 20:5(n-3), 16:0, 22:6(n-3) and 18:1(n-9). The results of gut content and fatty acid analyses indicate that all fish except the Channichthyidae share similar food resources irrespective of their depth distribution, i.e. benthic amphipods and polychaetes. A difference of the dietary spectrum can be observed with ontogenetic phases rather than between species, as high values of typical calanoid copepod marker fatty acids as 22:1(n-11) indicate that younger (smaller) specimens include more zooplankton in their diet.

    Short notes and reviews A Storthyngura (Crustacea, Isopoda) from the Bellingshausen Sea, Antarctica (2000)
    In:  Contributions to Zoology (1383-4517) vol.68 (2000) nr.4 p.261
    Details
    Publikationsdatum: 2015-05-08
    Beschreibung: During the expedition ANT XI/3 with RV Polarstern 17 multiple corers were taken in the Bellingshausen Sea. From this material only a single, immature isopod was sorted. This specimen is a manca II of a presumably new species of the genus Storthyngura. However, as it is immature and only a single specimen was sampled, more material of this species will have to be collected prior to the description of a new species.

    Redescription of Echinomunna horrida Vanh\xc3\xb6ffen, 1914, a highly derived and rare species from the Antarctic (Crustacea, Isopoda, Munnidae) (1999)
    In:  Bulletin Zoologisch Museum vol. 17 no. 2, pp. 9-16
    Details
    Publikationsdatum: 2024-01-12
    Beschreibung: During an expedition with RV Polarstern (1998) a male specimen of Echinomunna horrida was collected in the supranet of an epibenthic sledge in the Weddell Sea, Antarctica. Due to an incomplete and poor description by Vanh\xc3\xb6ffen (1914) a redescription is necessary on the basis of the male from the Weddell Sea and the female syntypes from the East Antarctic.

    Sphaeromatidae (Crustacea, Isopoda) of the Beagle Channel and description of Cymodopsis beageli n. sp (1998)
    In:  Beaufortia vol. 48 no. 7, pp. 137-161

    Publikationsdatum: 2024-01-12
    Beschreibung: During an expedition with RV Victor Hensen (1994) and the RV Polarstern (1996) Isopoda Sphaeromatidae were collected in and off the eastern entrance of the Beagle Channel. The species found, Caecocassidias patagonica Kussakin, 1967, Cassidinopsis emarginata (Gu\xc3\xa9rin-M\xc3\xa9neville, 1843) and Moruloidea darwinii (Cunningham, 1871), were previously all poorly or insufficiently described; therefore a redescription is presented herein. Exosphaeroma gigas (Leach, 1818) was also collected frequently, but it was already redescribed earlier and thus only the localities are presented. Moreover, a new species, Cymodopsis beageli, n.sp., which is most closely allied to Cymodopsis sphyracephalata Hurley & Janssen, 1977, is described from the Beagle Channel.
