Adaptive responses and transgenerational plasticity of a submerged plant to benthivorous fish disturbance

Benthivorous fish dominance in some subtropical lakes may alter submerged plant growth, reproduction, and progeny germination by changing water-submerged plant-algae interactions. We conducted mesocosm experiments to examine the effects of three densities of benthivorous fish, Misgurnus anguillicaudatus, on the water properties, the growth, asexual reproduction, and the germination of turions of Potamogeton crispus L.
The dataset includes water environment characteristics, macrophyte traits, algae traits, and sediment nutrient characteristics. Macrophyte traits include morphological, stoichiometric, turion traits, and germination traits., Macrophytes and sediment samples: All plants were harvested and carefully washed with tap water for later measurements. The branching number of P. crispus in each tank was counted. Measuring shoot length and root length with a straightedge (cm). All the plants were divided into leaf, root, stem, and turion. To determine the dry weight (DW), all leaves, roots, and stems were dried with bibulous paper, weighed, oven-dried at 70 °C to constant weight, and weighed (g). Twenty turions of each tank were randomly selected, oven-dried at 70 °C to constant weight, and weighed to determine the dry weight (DW). The remaining biomass was calculated according to the relative proportion. In each tank, the total biomass of each species was the sum of the DW of each plant organ. The dried plant and sediment samples were meticulously ground into a fine powder to determine C, N, and P. An elemental analyzer (UNICUBE, Elementar, Germany) was then used to analyze the N and C content in both plant tissues a..., , The dataset includes water environment characteristics, macrophyte traits, algae traits, and sediment nutrient characteristics. There are no missing values in this dataset.
