These are data from the paper: “Effect of light on macrophyte sprouting and assessment of viable seedbank to predict community composition” Sediments cores from each lake were pooled and homogenized and placed in trays with controlled lighting and temperature. Germination was determined for low light conditions (low water clarity), higher light conditions (high water clarity) and a treatment with gibberellic acid to induce germination and sprouting (maximum emergence – called maximum germination in the JAPM publication). Trays were examined weekly for newly sprouted plants that were identified to species and enumerated.
The data include propagule counts from the experiments and associated data. Eight data files are provided: AnnPropagulesbyTaxa; RileyPropagulesbyTaxa; Riley2mPropagulesbyTaxa, RileyAnnSeedbankvsPI; RileyAnnWeeklyTotalPropagules; RileyAnnWeeklyCumulativePropagules; RileyAnnUnsproutedSeeds; Taxonomic_Shorthand_KeyRileySeedbank. Details are provided in the SeedBankDRUMReadme file.
