“…In this sense, despite the dominant role of microalgae carbon to higher trophic levels (e.g., Arau ´jo-Lima et al, 1986;James et al, 2000;da Lopes et al, 2007), there is evidence that carbon from macrophyte detritus may also be important for invertebrates and fish in some ecosystems (Neill & Cornwell, 1992;Bunn & Boon, 1993;Thorp et al, 1998;Hart & Lovvorn 2003;Peel et al, 2019). In addition to providing organic matter for detritivorous organisms, macrophytes also provide food to aquatic and terrestrial herbivores (Jepsen & Winemiller, 2007;Martinez et al, 2013;Marchese et al, 2014;Bakker et al, 2016;Wolters et al, 2018;Crema et al, 2019;Franceschini et al, 2020). Thus, through photosynthesis and primary production, macrophytes have an important role in food webs of shallow ecosystems, which will translate into an increase in production of fish and of other animals used by humans (provisioning services).…”

“…The macrophyte community (hereafter ''macrophytes'') is considered a key element in freshwater ecosystems, especially in shallow ones (Scheffer, 2004;Jeppesen et al, 2007a, b). These plants change the physical and chemical environment (Bini et al, 2010;Pinero-Rodriguez et al, 2020), participate intensively in nutrient cycling (Carignan & Kalff, 1980;Wetzel, 2001;Wahl et al, 2021), produce biomass which is used by herbivores and detritivorous (Martinez et al, 2013;Peel et al, 2019;Franceschini et al, 2020) and provide habitat for other communities (Dibble et al, 2006;Dibble & Thomaz, 2009;Gething et al, 2020;Deosti et al, 2021), with consequences for higher trophic levels (Gomes et al, 2012;dos Santos et al, 2020;Paz Cardozo et al, 2021;Yofukuji et al, 2021).…”

Ecosystem services provided by freshwater macrophytes

Macrophytes are considered key components of aquatic ecosystems and they also provide multiple benefits for humans. In this review, I identified and exemplified 26 types of ecosystem services provided by macrophytes. The most important supporting services provided by these plants are related to nutrient cycling and provisioning of habitat, but macrophytes also participate in water cycling and gases production. The presence of macrophytes and their activity enhance water purification and disease control which are important regulating services. Provisioning services are provided in the form of food at the local and global scale (e.g., rice), fiber, biochemicals, natural medicine and ornamental resources. Cultural services are provided in the form of spiritual and religious artifacts and local knowledge systems of communities which depend on macrophytes for surviving. Other cultural services are associated with educational activities, art inspiration, esthetic values in aquatic gardens and ponds, uses for leisure, recreation and ecotourism. There is evidence that the efficiency of ecosystem functioning, the provision of ecosystem services and ecosystem stability is enhanced by macrophyte diversity. Because macrophyte communities provide important benefits for humans, their conservation and restoration, where necessary, are important for human well-being.

“…Harvesting directly affects the N and P cycles in the water. Currently, due to excess N, P, and other nutrients, submerged macrophytes overgrow and bloom in many lakes 7 . As the seasons change, the decomposition of many submerged macrophyte residues causes serious secondary pollution, which poses a great threat to the safety of aquatic ecosystems 8 .…”

Harvesting is an important method used to control the overproduction of Potamogeton crispus in lakes. A three-year comparative field study was performed in a eutrophic lake (harvested area) and its connected lake (non-harvested area) to determine the effects of harvesting on the phosphorus (P) composition and environmental factors in the water and sediment. Results revealed that harvesting significantly reduced the dissolved total P and dissolved organic P (DOP) and increased the alkaline phosphatase activity and particulate P (PP) in the water. No significant differences were detected in the water total P (TP), soluble reactive P, chlorophyll-a, pH, and dissolved oxygen between the harvested and non-harvested areas. Sediment TP and organic P (OP) were significantly reduced in the harvested area. Harvesting changed the P composition in the water. In the non-harvested area, P was mainly formed by DOP (40%) in the water body, while in the harvested area, PP was the main water component (47%). Harvesting increased the proportion of inorganic P (IP) in the sediment and decreased the proportion of OP. In the water, the IP to TP ratio in the non-harvested and harvested areas were 58.26% and 63.51%, respectively. Our results showed that harvesting changed the P composition in the water and sediment. In the harvesting of submerged vegetation, our results can serve as a reference for the management of vegetation-rich lakes.
