The dataset covers photos of the microcosms used to collect the seasonal data for <i>Lemna<i> sp. populations; the results of the pre-experiments to study the appropriate nutrient levels for the growth of <i>Lemna<i> sp.; the experimental datasets covering experimental data over 2 consecutive years including biotic (biomass and numbers of fronds) and abiotic data from the aquatic habitat of <i>Lemna<i> sp. in the temperate climate region and the statistical regression results; and finally the weather data. The dynamics of biomass and numbers of fronds of <i>Lemna<i> sp. were studied using 100 small microcosms. Each microcosm was 45 cm in internal diameter, with a surface area of 0.174 m2, a height of 67 cm, a water depth of 56.5 cm and a volume of 26.56 L. The microcosms were buried in the ground to reduce fluctuation of water temperatures, and to provide conditions comparable to a small (edge-of-field) pond or ditch. Parameters monitored included biomass (fresh and dry weight), seasonal growth rates, relevant environmental parameters and weather data. This dataset includes the 2-year experimental biotic (biomass and numbers of fronds) and environmental data (water quality data, weather data).
