“…The results showed differences in relative growth rate (RGR) among species during the growing season with almost all species having the highest growth rate in June and also varying in the range of 0.002-0.106 day À1 . The relative growth rate of the specific emergent species used in this study are somewhat in the same range as 0.003-0.13 day À1 found by Manolaki et al (2020) and within the range of relative growth rates (0.007-0.109 day À1 ) found by Nielsen and Sand-Jensen (1991) for 14 submerged species. However, the growth capacity of submerged species is much lower than the one recorded in relation to the emergent species (Manolaki et al, 2020).…”

“…However, recent studies suggest that higher biodiversity both in terms of species number and of species growth forms (such as more emergent species, floating leaved and submergent species) can significantly increase nutrient removal from a system due to important differences in their nutrient uptake strategies (e.g. Bouchard et al, 2007;Choudhury et al, 2018;Manolaki et al, 2020) via niche complementarity (Choudhury et al, 2018;Olesen et al, 2018) and the extension of the nutrient period across seasons (Manolaki et al, 2020).…”

“…Therefore, information about the propagation of tolerant species in relation to species establishment, survival rate and size suitability for planting, will support the high number of plants required for the new CWs. Still, their survival and establishment rate can vary among plant species during the growing season, with some species being most productive in spring, summer and/or autumn (Manolaki et al, 2020).…”

Constructed wetlands have become a widely used tool for reducing nutrient loading from agriculture drainage water running to aquatic ecosystems. To ensure a high nutrient removal efficiency, it is often suggested to use macrophytes to retain or remove nutrients via uptake and through the denitrifying biofilm. In Europe, Phragmites australis and Typha spp are the most commonly used aquatic plants in constructed wetlands (CWs) with free surface flow, and these species often form monocultures in the wetlands. In order to achieve a more diverse vegetation, there is a need to introduce more plant species. Creating a mass production of plant material reduces both handling time and the risk of depleting and disturbing vegetation in natural habitats such as streams or lakes. However, a successful and continuous production of such material during growing seasons requires knowledge of the selected species' establishment and propagation. We examined the relative growth rate (RGR) of six emergent macrophyte species collected from streams and small lakes located in Mid Jutland (Denmark), in seasonal experiments from March to October in order to determine the most efficient time period for their propagation. We found that all species had highest RGR in June, and that several species showed high growth efficiency from April to August. The results showed that it is possible to have a full production of emergent macrophytes throughout the growing season, and therefore, we suggest to propagate plants for use in constructed wetlands in order to enhance biodiversity and ecosystem functioning.

“…The ability of nutrient uptake by aquatic plants differed seasonally due to the change in water and sediment nutrient content in response to the seasonal changes in plant growth requirements following seasonal changes in biomass production ( Manolaki et al 2020 ). The above- and belowground organs of the water primrose exhibited significant seasonal variation in their inorganic nutrients.…”

“…Aquatic macrophytes, including floating life forms, regulate freshwater ecosystem services respecting nutrient remediation and water purification ( Manolaki et al 2020 ). Aquatic plants can sequester high amounts of nutrients from wetlands by storing them in the roots and/or shoots ( Lai et al, 2011 , Eid et al, 2020 ).…”

The current work investigates the capacity of the water primrose ( Ludwigia stolinefera ) to sequester inorganic and organic nutrients in its biomass to restore eutrophic wetlands, besides its nutritive quality as fodder for animals. The nutrient elements and nutritive value of the water primrose were assessed seasonally in polluted and unpolluted watercourses. The water primrose plants’ highest biomass was attained during summer; then, it was significantly reduced till it reached its lowest value during winter. In the polluted canal, the plant root and shoot accumulated higher contents of all nutrient elements (except Na and Mg) rather than in the unpolluted Nile. They accumulated most investigated nutrients in the growing season during summer. The shoots accumulated higher contents of N, P, Ca, and Mg than the root, which accumulated higher concentrations of Na and K. Therefore, summer season is the ideal time to harvest water primrose for removing the maximum nutrients for restoring eutrophic watercourses. The aboveground tissues had the highest values of ether extract (EE) during spring and the highest crude fibers (CF) and total proteins (TP) during summer. In contrast, the belowground tissues had the lowest EE, CF, and TP during winter. In spring, autumn, and winter seasons, the protein content in the grazeable parts (shoots) of the water primrose was within the range, while in summer, it was higher than the minimum requirement for the maintenance of animals. There was a decrease in crude fibers and total proteins, while an increase in soluble carbohydrates content in the below- and above-ground tissues of water primrose under pollution stress. The total protein, lipids, and crude fibers of the aboveground parts of water primrose support this plant as a rough forage.

Elevated concentrations and loads of nutrients in the South Platte River and Cherry Creek in Denver, Colorado, may have adverse effects on those streams and downstream water bodies, including increased production of algae, eutrophication, and decreased recreational opportunities. This article describes streamflow and concentrations and loads of nutrients for the South Platte River and Cherry Creek in Denver based on data collected during two longitudinal Lagrangian sampling campaigns in low-flow conditions in fall of 2019 and 2020. The results are used to assess sources and sinks of nutrients in the study area and help to establish baseline conditions against which future changes in nutrient concentrations and loads can be assessed. Discharges from Chatfield and Cherry Creek Reservoirs, storm drains, and most tributaries to the South Platte River, and Cherry Creek were generally small sources of streamflow and nutrient loads in both years. The Marcy Gulch, South Platte Water Renewal, and Robert W. Hite wastewater treatment plants were larger sources of streamflow and nutrient loads. The BurlingtonDitch was a sink for streamflow and nutrient loads, diverting more than 95% of the South Platte River during the two sampling campaigns. Most other sinks were associated with decreases in streamflow between sampling sites. Golf courses were a potential source of nutrients for Cherry Creek but not for the South Platte River.
