Species-specific relationship for Angiospermae between spring sediment propagule density (lower inverted Y-axis on left side; data points separately shown: n = 3 for top and sub layer each), herbivorous waterfowl biomass (lower Y-axis on right side; average of cold, spring, and warm periods) and established species cover in two consecutive summer seasons (upper Y-axis; box = 25th percentile-median-75th percentile, whiskers = non-outlier range, crosses = outliers and extremes, n = 15). Ponds (X-axis) are ordered from high to low propagule densities, excluding those in which the macrophyte species is absent. Cal. obt., Callitriche obtusangula; Cer. dem., Ceratophyllum demersum; Elo. nut., Elodea nuttallii; Pot. cri., Potamogeton crispus.
