“…3D). Many of these studies are based on laboratory experiments that investigate the ability and rate at which FBs can ingest (and, in some studies digest) and thus, remove (certain compartments of) phytoplankton from the water column, including harmful derivatives, such as hepatotoxic microcystins and nodularins (Pham et al ., 2016; Buelow & Waltham, 2020; Silva et al ., 2020). A number of studies provide evidence for these mechanisms in situ , often through mesocosm experiments.…”

Identification of ecosystem services, i.e. the contributions that ecosystems make to human well-being, has proven instrumental in galvanising public and political support for safeguarding biodiversity and its benefits to people. Here we synthesise the global evidence on ecosystem services provided and disrupted by freshwater bivalves, a heterogenous group of >1200 species, including some of the most threatened (in Unionida) and invasive (e.g. Dreissena polymorpha) taxa globally. Our systematic literature review resulted in a data set of 904 records from 69 countries relating to 24 classes of provisioning (N = 189), cultural (N = 491) and regulating (N = 224) services following the Common International Classification of Ecosystem Services (CICES). Prominent ecosystem services included (i) the provisioning of food, materials and medicinal products, (ii) knowledge acquisition (e.g. on water quality, past environments and historical societies), ornamental and other cultural contributions, and (iii) the filtration, sequestration, storage and/or transformation of biological and physico-chemical water properties. About 9% of records provided evidence for the disruption rather than provision of ecosystem services. Synergies and trade-offs of ecosystem services were observed. For instance, water filtration by freshwater bivalves can be beneficial for the cultural service 'biomonitoring', while negatively or positively affecting food

“…The respiration, filter feeding, digestion, and reproduction functions of C. fluminea are rooted in its gill, mantle, digestive gland, and gonad 19 , 20 . Recently, studies have found that the density and biomass of C. fluminea populations were significantly reduced in waters with cyanobacteria outbreaks 21 , 22 , indicating that cyanobacteria secondary metabolites had adversely affected the organism. Although detoxification and antioxidant systems do not directly impact organ functions, they play a critical role in maintaining cellular homeostasis when an organism is exposed to environmentally toxic chemicals.…”

“…When these two systems are unable to endure the toxicity of MaE, tissue damage and organ function failure may occur 23 . Currently, there are few studies on the adverse effects of MaE on C. fluminea organs and their functions 22 . Therefore, exploring the ecotoxicological effects of MaE on C. fluminea , in particular the response of their important organs to MaE exposure, is urgently required.…”

Cyanobacteria bloom and the secondary metabolites released by the microorganism are extremely harmful to aquatic animals, yet study on their adverse effects in zoobenthos is rare. Corbicula fluminea widely distributed in freshwater environment with algal blooms. It is a typical filter feeding zoobenthos that may be affected by the secondary metabolites of cyanobacteria due to its high filtering rate. In this study, C. fluminea was exposed to Microcystis aeruginosa exudates (MaE) for 96 h, which was obtained from 5 × 105 cells/mL and 2.5 × 106 cells/mL exponential stage M. aeruginosa culture solution that represented cyanobacteria cell density needs environmental risk precaution control and emergent control, respectively. The responses of C. fluminea critical organs to MaE were analyzed and evaluated based on histopathological sections, antitoxicity biomarkers, and organ function biomarkers. The results showed that all the organs underwent structural disorders, cell vacuolization, apoptosis, and necrosis, and the damage levels increased as MaE concentration increased. The detoxification and antioxidant defense systems biomarkers in each organ response to MaE exposure differently and the level of reaction improved when MaE concentration increased. The siphon rate and acetylcholinesterase activity showed that the filtration function decreased significantly as the MaE concentration increased. Increased activity of glutathione S-transferase and amylase in the digestive gland indicate that it is the major detoxification organ of C. fluminea. Increased vitellogenin concentration and enlarged oocytes in the gonad indicate that MaE may have an estrogenic effect on C. fluminea. This study demonstrates that cyanobacteria threat benthic bivalves by inducing oxidative stress, inhibiting filtering feeding system, and disturbing digestion system and reproduction potential of C. fluminea.

A number of previous studies often used living cells (Ferrao-Filho et al, 2000;Lurling, 2003;Dionisio Pires et al, 2005;da Costa et al, 2013;Pham et al, 2015a), purified MCs (Chen et al, 2005;Ortiz-Rodríguez et al, 2010;Ortiz-Rodríguez et al, 2012;Hulot et al, 2012), or cyanobacterial crude extracts (CCEs) (Pietsch et al, 2001;Dao et al, 2010;Hulot et al, 2012;Dao et al, 2013a;Pham et al, 2016;Pawlik-Skowrońska et al, 2019;Toporowska et al, 2020) in toxicity tests. In fact, water from cyanobacterial blooms contains not only MC but also a mixture of multiple 4 substances which can cause unpredictable effects on zooplankton (e.g.…”

Cyanobacterial blooms often consist of mixtures of microcystin-producing and microcystin-free species and both of them can cause unpredictable effects on aquatic organisms. In this work, the subchronic effects of the cyanobacterial crude extracts (CCEs) from microcystin-producing and microcystin-free cyanobacteria, with different microcystin concentrations (1, 10, and 50 µg L −1) on Daphnia magna (D. magna) were investigated. The life-history trait responses of D. magna to CCEs were determined based on survival, reproduction, and somatic growth. In addition, the physiological response represented by the feeding rate of D. magna on green algae (Scenedesmus sp.) after exposure to both type of crude extracts was also estimated. Our results showed that both microcystin-containing (MCCE) and microcystin-free (NCCE) crude extracts insignificantly reduced survival but strongly enhanced reproduction and somatic growth of organisms. However, the degradation of eggs and neonates of the gravid females exposed to the CCEs was observed. Besides, the feeding rate of D. magna exposed to MCCE has been increased significantly whereas no change in the feeding rate was observed for NCCE-exposed D. magna. In general, new and interesting aspects of the toxicity of MCCE and NCCE were obtained from this study and our study contributed to the understanding of the toxicity of Pseudanabaena sp. extract on D. magna under bioassays.
