    Description: Cells in multicellular organisms are genetically heterogeneous owing to somatic mutations. The accumulation of somatic genetic variation in species undergoing asexual (or clonal) reproduction (termed modular species) may lead to phenotypic heterogeneity among modules. However, abundance and dynamics of somatic genetic variation under clonal growth, a widespread life history in nature, remain poorly understood. Here we show that branching events in a seagrass clone or genet leads to population bottlenecks at the cellular level and hence the evolution of genetically differentiated modules. Studying inter-module somatic genetic variation, we uncovered thousands of SNPs that segregated among modules. The strength of purifying selection on mosaic genetic variation was greater at the intra-module comparing with the inter-module level. Our study provides evidence for the operation of selection at multiple levels, of cell population and modules. Somatic genetic drift leads to the emergence of genetically unique modules; hence, modules in long-lived clonal species constitute an appropriate elementary level of selection and individuality.

    Continuous thermosalinograph oceanography along RV ALKOR cruise track AL594 (2023)
    PANGAEA
    Details
    Publication Date: 2024-01-26
    Description: Underway temperature and salinity data was collected along the cruise track with a thermosalinograph (TSG) together with a SBE38 Thermometer. Both systems worked throughout the cruise. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No temperature calibration was performed. Salinity was calibrated with independent water samples taken at the water inlet. For details to all processing steps see Data Processing Report.

    Experiment on an artificial phytoplankton community in response to high CO2: relative importance assay and calculated relative importance (2022)

    Details
    Publication Date: 2024-03-22
    Description: This dataset includes information specific to the Eco-Evo assay applied to a long-term community selection experiment after 80,186, and 288 days. The community contained Emiliania huxleyi and Chaetoceros affinis (details about Species and genotypes used can be found in doi:10.1098/rsbl.2016.0774). The long-term community selection phase to ambient and high CO2 (400 and 1250ppm, respectively) started on the 10th of January 2017, details about the sorting phase in semi-continuous batch cycles can be found in doi:10.1594/PANGAEA.887780. Here, the raw data from the subsequent Eco-Evo assay are presented, as well as the calculated relative importance of species and genotype sorting.The first eco-evo Assay (after 80 days) previously served to validate the new method (https://doi.org/10.1111/1365-2435.13923) and Abundance (column 8) of Time 80 (first 25 rows) and the calculated relative contribution to total changes of that timepoint (column 28- first 4 rows) are also included in the previous dataset (https://doi.org/10.1594/PANGAEA.896220). Abundance-weighted means are calculated as the sum of each species' cell abundances multiplied with their respective trait, divided by the total cell abundance. Relative Importance of eco-evolutionary changes to the total change are calculated following the formula given in Hattich et al 2022 (https://doi.org/10.1111/1365-2435.13923).

    Experiments on coexisting phytoplankton species Chaetoceros affinis and Emiliania huxleyi in response to nutrients (2023)
    PANGAEA
    Details
    Publication Date: 2024-03-13
    Description: Measurements of cell size, cell density, nutrient concentration and genotype composition in a long-term experiment (182 days) with the marine phytoplankton species Chaetoceros affinis and Emiliania huxleyi, each consisting of nine genotypes. The species were cultivated together at three different nutrient regimes (10 N, 20 N, 30 N) with increasing nitrate supply in a semi-continuous batch cycle system. The genotype composition of both species was assessed after 49, 91, and 182 days using microsatellites. In a short-term experiment cell size and density of nine Chaetoceros affinis genotypes separately were measured after 7 days growth at seven nitrate levels (2.5, 5, 7.5, 12.5, 20, 30, and 45 μmol L−1 N).

    Description: Onboard, cephalopods were identified morphologically to the lowest taxonomic level possible (species, genus or family), and whole specimens were preserved in formalin as voucher. In addition, tissue samples of some specimen were collected and preserved in ethanol for barcoding and the genetic reference database used for eDNA metabarcoding.
