    Description: Copepod samples were taken during the Antarctic expedition PS 79 (ANT XXVIII/2) with RV Polarstern (Cape Town – Cape Town, 3 Dec 2011 – 5 Jan 2012). Copepods were collected at Station 53 (60° 3.22'S, 0° 2.14' E) in the Antarctic Weddell Gyre on 28 December 2011 by vertical bongo net hauls down to 300 m depth. Specimens of C. acutus (210 copepodids CV and 160 females) and of C. propinquus (125 females, no CV stages available) were gently sorted from the catch, maintained alive in filtered seawater at 0°C in a cooling container on board and transported to Germany at 0°C by airplane. Feeding carbon-labelled diatoms to these copepods during 9 days of feeding ,13C elucidated assimilation and turnover rates of copepod total lipids as well as specific fatty acids and alcohols. The 13C incorporation into these compounds was monitored by compound-specific stable isotope analysis (CSIA). The differences in lipid assimilation and turnover clearly show that the copepod species exhibit a high variability and plasticity to adapt their lipid production to their various life phases.

    Description: A combined stable isotope and fatty acid trophic biomarker approach was adopted for key zooplankton taxa and higher trophic positions of the northern Humboldt Current System to elucidate the pelagic food-web structure and to better understand trophic interactions. Samples covered an extensive spatial range from 8.5°S to 16°S and a vertical range down to 1,000 m depth. Immediately after each haul, specimens were sorted alive in the lab and apparently live and healthy individuals were stored in vials and deep-frozen at -80°C until further lipid and stable isotope analyses. The comprehensive data set covered over 20 zooplankton taxa and indicated that three biomass-rich crustacean species usually dominated the zooplankton community, i.e., the copepods Calanus chilensis at the surface and Eucalanus inermis in the pronounced oxygen minimum zone and the krill Euphausia mucronata, resulting in an overall low number of major trophic pathways toward anchovies. In addition, the semi-pelagic squat lobster Pleuroncodes monodon appears to play a key role in the benthic-pelagic coupling. By partly feeding on benthic resources and by diel vertical migration, P. monodon provides a unique pathway for returning carbon and energy from the sea floor to the epipelagic layer, increasing the food supply for pelagic fish.

    Description: Males of the four crab species Percnon affine (H. Milne Edwards, 1853), Grapsus albolineatus (Latreille in Milbert, 1812), Orisarma intermedium (Schubart &Ng, 2020), and Geothelphusa albogilva (Shy, Ng & Yu, 1994), were collected in the southern part of Taiwan in May 2007. Individuals were starved for 12 days and midgut glands were dissected before and after the starvation period. Midgut glands were lyophilized and total lipids were extracted with dichloromethane:methanol (2:1 per volume) and an aqueous solution of 0.88% KCl. Extracted lipid mass was determined gravimetrically. Lipid classes were separated and quantified using Thin-Layer Chromatography with an integrated flame ionization detector (MK-5 TLC/FID analyzer, Iatron Laboratories). Lipids were converted to fatty acids methyl esters (FAME) by applying methanol containing 3% concentrated sulfuric acid. FAMEs were quantified by gas chromatography equipped with a DB-FFAP column, a programmable temperature vaporizer injector, and a flame ionization detector. Helium was used as carrier gas. Fatty acids were identified by retention times and by using fish oil standard (Marinol). Data are supplement to: Stumpp et al (2021) Dietary preferences of brachyuran crabs from Taiwan for marine or terrestrial food sources: evidence based on fatty acid trophic markers accepted for publication in Frontiers in Zoology

    Description: Small copepod genera play an important role in marine food webs and biogeochemical fluxes but have been neglected in many studies. Abundance, biomass and carbon consumption rates of small- (〈1 mm prosome length (PL)), medium- (1-1.5 mm PL) and large-sized (〉2 mm PL) copepods along a cross-shelf transect in the southern Benguela upwelling system were determined using rather high taxonomic resolution. Zooplankton samples were collected with a Multinet (Hydrobios Multinet midi, 5 nets with 200 µm meshsize) during the Meteor cruise M153 in February/March 2019. Calanoids contributed on average 55 ± 19% to total copepod abundance and 82 ± 13% to total copepod biomass. Small-sized Oithona spp. (119/114 mg C m-2 d-1) and Clauso-/Paracalanidae (87/263 mg C m-2 d-1) as well as large-sized Calanoides natalis (47/193 mg C m-2 d-1) were the dominant consumers at the most inshore stations. Small and medium-sized copepodite stages of Metridia lucens were also important, especially towards the continental slope. At offshore stations, Para-/Clausocalanidae (17-27 mg C m-2 d-1), Oithona spp. (9-16 mg C m-2 d-1), Pleuromamma spp. (0-16 mg C m-2 d-1), Calanus agulhensis (0-15 mg C m-2 d-1), Acartia spp. (0-12 mg C m-2 d-1), C. natalis (0-10 mg C m-2 d-1) and M. lucens (2-6 mg C m-2 d-1) were dominant consumers. Hence, usually small- and medium-sized copepods dominated total copepod ingestion, emphasizing that inadequate representation of small copepods will lead to significant underestimations and misinterpretations of the functioning of zooplankton communities, and finally to inadequate biogeochemical models.

    In:  Supplement to: Lischka, Silke; Hagen, Wilhelm (2006): Seasonal lipid dynamics of the copepods Pseudocalanus minutus (Calanoida) and Oithona similis (Cyclopoida) in the Arctic Kongsfjorden (Svalbard). Marine Biology, 150(3), 443-454, https://doi.org/10.1007/s00227-006-0359-4
    Publication Date: 2024-04-24
    Description: Seasonal lipid dynamics of various developmental stages were investigated in Pseudocalanus minutus and Oithona similis. For P. minutus, the dominance of 16:1(n−7), 16:4(n−3) and 20:5(n−3) fatty acids indicated a diatom-based nutrition in spring, whereas 22:6(n−3), 16:0, 18:2(n−6) and 18:1(n−9) pointed to a flagellate-based diet during the rest of the year as well as omnivorous/carnivorous low-level feeding during winter. The shorter-chain fatty alcohols 14:0 and 16:0 prevailed, also reflecting biosynthetic processes typical of omnivores or carnivores. Altogether, the lipid signatures characterized P. minutus as an opportunistic feeder. In contrast, O. similis had consistently high amounts of the 18:1(n−9) fatty acid in all stages and during all seasons pointing to a generally omnivorous/carnivorous/detritivorous diet. Furthermore, the fatty alcohol 20:1(n−9) reached high percentages especially in adult females and males, and feeding on Calanus faecal pellets is suggested. Fatty alcohols, as wax ester moieties, revealed significant seasonal variations in O. similis and a seasonal trend towards wax ester accumulation in autumn in P. minutus. P. minutus utilized its lipid deposits for development in the copepodite stages III and IV and for gonad maturation in CV and females during the dark season. However, CVs and females depended on the spring phytoplankton bloom for final maturation processes and reproduction. O. similis fueled gonad maturation and egg production for reproduction in June by wax esters, whereas reproduction in August/September co-occurred with the accumulation of new depot lipids. Both species revealed significantly higher wax ester levels in deeper (〉50 m) as compared to surface (0–50 m) dwelling individuals related to a descent prior to overwintering.
