Freshwater Cyanobacteria Global Impacts and New Challenges

Dear Colleagues,

Freshwater cyanobacteria are cosmopolitan microorganisms. As cyanotoxins producers their occurrence, particularly on toxic forms, can impair ecosystems safety, human health or water quality. Freshwater resources such as lakes, lagoons, ponds, rivers and reservoirs on their multiple demands (drinking, water provision, irrigation, recreational and sustainable) carry a need on continuous surveillance on freshwater cyanobacteria. On these on cyanotoxins such as microcystins, cylindrospermopsins, anatoxins and saxitoxins are a persistent problem on freshwater ecosystems demanding a constant endeavour since their occurrence can result overall on intoxication episodes that can lead on serious illnesses resulting on death on humans, wildlife or even cattle. Likewise bloom formation (CyanoHABs) usually a result of anthropogenic activities, increased eutrophication and rise on temperature are on need on report on describing bloom-forming cyanobacteria species, toxin amounts, related cyanotoxins-producing taxa as well as on climate change impacts. Recently new toxin-driven cyanobacteria cyanotoxins were reported on the US and consequently its global search is imperative on secure ecosystems, promote human health, foster water quality and water management practices without overlooking the sustainability of freshwater ecosystems. Studies on new toxic cyanobacteria toxin-production can contribute on improving our understanding on freshwater cyanobacteria toxin impacts and on in deep global search. On this Special Issue studies on all sciences are most welcomed aiming on fostering global search on toxic cyanobacteria and on their cyanotoxins towards improvement on regulations. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

• Toxic cyanobacteria diversity;
• Toxin production on undescribed taxa;
• New cyanotoxins;
• Occurrence on known cyanotoxins;
• Toxin production on known taxa;
• Public health impairment;
• Water quality impairment;
• Toxin impacts on sustainable ecosystems;

Climate change impacts on CyanoHABs. We look forward to receiving your contributions.

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. Microorganisms 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 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
