    Abundance and biomass of macrofauna in the German Bight from 2012 to 2015 (2024)
    PANGAEA
    Details

    Description: The long-term ecological research benthic monitoring comprises four representative permanent stations (SSd, Slt, FSd and WB) that have been sampled countinuously since 1969. The four stations are representative for the different benthic communities in the German Bight. Inter-annual variability and possible long-term trends were analysed based on spring-time samples since 1969. Earlier datasets have been published in the publication series https://doi.org/10.1594/PANGAEA.667646. Macrozoobenthos of soft-bottom benthic community was collected by van-Veen grabs. This dataset contains the continuation of this time series with the samples collected in spring between 2012 and 2015 each year in the North Sea, German Bight. Data for each campaign comprise four stations in the German Bight, sampled by grab samples (infauna). Biodiversity data of species include abundance (count data) and biomass (wet mass, g) per sample.

    Hydrolysis rates of biodegradable plastics by the gastric fluid and enzymatic activities of the gastric fluid of the edible crab Cancer pagurus (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The hydrolytic degradation of biodegradable and conventional plastics by the gastric fluid of the edible crab Cancer pagurus were assayed in-vitro with pH Stat titration. Suspensions of different microplastics were incubated with gastric fluid at 15 °C in artificial seawater. Rates of hydrolysis, as determined by counter-titration with a diluted base (NaOH), was recorded for two hours. The gastric fluid was separated by anion exchange chromatography into 65 fractions. Again, three pools of fractions were tested for their hydrolytic potential with a plastic based on polylactic acid at 30°C. Enzyme assays with fluorogenic substrates were performed with each of the 65 fractions of the gastric fluid. Methylumbelliferone derivatives of fatty acid esters (MUF-butyrate, MUF-heptanoate and MUF-oleate) were used as substrates in buffer at different pH ranging from 5 to 9 and at a temperature of 25°C. The increase in fluorescence was measured with a microplate reader. Analogously, the effect of a detergent (sodium dodecyl sulfate) on the enzymatic activity was measured. All measurements were conducted under controlled laboratory conditions.
