One of the oldest groups of organisms known—from fossil records dating back more than 3.5 billion years—the cyanobacteria (or "blue-green algae") are recognized to produce a diverse repertoire of biologically active secondary metabolites. Occurring ubiquitously in both free-living and symbiotic form, and perhaps most conspicuously in aquatic habitats as part of so-called "harmful algal blooms" (HABs), several of these bioactive cyanobacterial metabolites have been clearly identified as "toxins" that negatively impact human, animal and ecosystem health—including acute toxicoses and chronic, long-term health effects—in association with toxigenic HABs, contamination of drinking water, transfer through food-webs and other potential exposure routes. Moreover, in light of global climate change, and particularly measurable rises in global temperature, as well as increased fluxes of certain nutrients (i.e., nitrates, phosphates) from pollutant run-off (e.g., fertilizers, sewage/waste) and other anthropogenic sources, it has been suggested that cyanobacteria—including toxin-producing taxa—and cyanobacterial HABs may be increasing in abundance, and thus represent an emerging human and environmental health concern. This special issue will present, through both primary research and comprehensive review papers, up-to-date findings on these so-called “cyanotoxins” particularly focusing on their chemistry and toxicology, as well as aspects (e.g., monitoring strategies) related to mitigating their potential health effects, and understanding of the ecological dynamics related to the toxins and their production.

Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on theInstructions for Authors page. Toxins 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 800 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Effect of Nutrient Limited Cyanobacteria on Protease Inhibitor Production and Daphnia Magna Fitness

Abstract: The occurrence of cyanobacterial blooms in lakes and ponds has, at least partly, been attributed to cyanotoxins, which negatively affect the major grazer of planktonic cyanobacteria, i.e., Daphnia. Among these cyanotoxins are the wide-spread protease inhibitors (PIs). Here we report that growth limitation by nutrients (i.e., phosphate and nitrate) of a strain of Microcystis aeruginosa led to changes in PI-content. This altered PI-content was accompanied by changed effects on the fitness of Daphnia, measured as IC50-values of inhibition of digestive proteases and as reduction of somatic growth rate.
