Special Issue Information

Dear Colleagues,

Freshwater bivalves, which comprise over 1200 species, are distributed across Asia, Europe, North America, Africa, Australasia, and South America. As "ecosystem engineers", they play an indispensable role in the nutrient cycling and energy flow processes in freshwater ecosystems. Additionally, many species hold significant economic value, serving as food sources and in pearl cultivation. However, due to escalating threats, including environmental pollution, habitat modification, over-harvesting, and climate change, freshwater bivalves are now among the world’s most imperiled taxonomic groups, with 40% of species being near-threatened, threatened, or extinct. Therefore, urgent conservation action is needed.

This Special Issue provides an opportunity to highlight innovative research on the ecology and conservation of freshwater bivalves. We welcome manuscripts covering, but not limited to, biodiversity, molecular evolution, taxonomy, ecology, ecotoxicology, and conservation. By advancing the knowledge of their organismic and molecular diversity, values, and ecosystem services, this Special Issue seeks to inform a proactive approach to the conservation of these declining species.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs).

Abstract
Eutrophication of water bodies significantly accelerates water quality degradation, leading to the decline of aquatic organisms. To evaluate the synergistic restoration effects of submerged macrophyte Hydrilla verticillata and filter-feeding bivalve Anodonta woodiana on hypereutrophic water, a 40-day mesocosm simulation experiment in hypereutrophic aquatic [...] Read more.
Eutrophication of water bodies significantly accelerates water quality degradation, leading to the decline of aquatic organisms. To evaluate the synergistic restoration effects of submerged macrophyte Hydrilla verticillata and filter-feeding bivalve Anodonta woodiana on hypereutrophic water, a 40-day mesocosm simulation experiment in hypereutrophic aquatic ecosystems was conducted by setting up four treatments: control group (CK), A. woodiana group (Aw), H. verticillata group (Hv), and combined H. verticillata + A. woodiana group (HA). The results indicated that the combined application of H. verticillata and A. woodiana significantly reduced total phosphorus (TP), chlorophyll a (Chl a) concentration, and turbidity in the water, with removal rates reaching 58.3%, 60.6%, and 85.4%, respectively. The introduction of A. woodiana substantially altered the algal community composition. At the end of the experiment, the average proportion of cyanobacteria in the CK and Hv groups was 55.6%, whereas in the Aw and HA groups it decreased to 36.0%. Both total phosphorus and water-soluble phosphorus contents in H. verticillata tissues were significantly lower in HA compared to Hv, indicating that the combined treatment could reduce the risk of internal phosphorus release after H. verticillata senescence. These findings collectively demonstrate that the combination of H. verticillata and A. woodiana represents an efficient and environmentally friendly ecological restoration technology of eutrophic waters.
