“…For filamentous or colonial taxa, there was no significant interactive effects; rather filamentous cyanobacteria were more sensitive to macrophytes and colonial cyanobacteria to bivalves. The differential sensitivity of cyanobacterial taxa to different biomanipulation approaches has been noticed previously (Gazulha et al, 2012;Amorim and Moura, 2020), the reason being that cyanobacteria are a diverse and morphologically complex group of prokaryotes with different key ecological traits thus eliciting disparate responses (Mantzouki et al, 2016;Rangel et al, 2020).…”

“…In addition, SMs can facilitate nutrient uptake from the water column and sediment (Sand-Jensen and Borum, 1991) and reduce sediment resuspension (Horppila and Nurminen, 2003). Earlier studies involving small-scale experiments (Barrow et al, 2019;Amorim and Moura, 2020) and natural aquatic ecosystems (Chao et al, 2022;Peng et al, 2022) have repeatedly reported that the restoration of SMs decreases the phytoplankton abundance and increases water clarity. Thus, usage of SMs is a prospective tool for the elimination of algal blooms (Jeppesen et al, 2007b).…”

Freshwater ecosystems are threatened by eutrophication, which causes persistent and harmful algal blooms. Filter-feeding bivalve mollusks and submerged macrophytes (SMs) alleviate the eutrophication effects by inhibiting phytoplankton biomass blooms. However, very little is known about whether and how the combined manipulation of filter-feeding bivalves and SMs control eutrophication and influence phytoplankton assemblages. Here, we performed a nutrient-enriched freshwater mesocosm experiment to assess the combined effects of the filter-feeding bivalve Cristaria plicata, a cockscomb pearl mussel, and the macrophyte Hydrilla verticillate on the biomass and composition of phytoplankton assemblages. We found that addition of C. plicata and H. verticillate decreased the water nutrient concentrations and suppressed overall phytoplankton biomass. Further, distinct differences in taxa between restoration and control treatments were observed and noticeably competitive exclusion of cyanobacteria in the restoration treatments occurred. An antagonistic interaction between filter-feeding bivalves and SMs was only detected for total cyanobacteria biomass demonstrating that a larger magnitude of SM restoration may override the effect of filter-feeding bivalves. Our results suggest that manipulation, through the addition of bivalves as grazers, associated with the restoration of SMs, is an efficient approach for reducing cyanobacterial blooms and alleviating eutrophication.

“…As a consequence of these mechanisms, along with direct absorption of nutrients by macrophytes, water quality improves. In addition to the physical interference and absorption of nutrients (Wetzel, 2001;Jabłon ´ska et al, 2021), macrophytes contribute to reducing algae growth (and eutrophication) through at least two other mechanisms: (i) provisioning of habitat that enhances the density of zooplankton (Meerhoff et al, 2007) and, in some macrophytes, (ii) release of allelopathic substances that inhibit phytoplankton development (Hilt & Gross, 2008;Amorim & Moura, 2020). These mechanisms help maintain a clear-water state, at least in temperate lakes.…”

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.

“…Therefore, the presence of macrophytes hinders the growth of phytoplankton (Scheffer et al, 1993;van Donk et al, 1993). Besides competition for nutrients, macrophytes have been shown to suppress phytoplankton even under nutrient saturation (Amorim and Moura, 2020;Vanderstukken et al, 2011). The production of allelochemicals by certain macrophyte species also has a strong impact on phytoplankton (Körner and Nicklisch, 2002;Švanys et al, 2014) especially cyanobacteria, making macrophytes a useful tool in cyanobacteria management (Bakker and Hilt, 2016;Wang et al, 2012).…”
