Special Issue Information

Dear Colleagues,

Climate change will differentially modify the levels and frequency of the appearance of natural toxins in the world around us depending on a variety of factors, including longitude, latitude, altitude and geography. This Special Issue will focus on studies that investigate changes in the occurrence of fungal, algal and plant derived toxins that directly or indirectly affect human health. Topics covered will include: (i) shrinkage, expansion or relocation of the boundaries of specific toxins; (ii) Changes in frequency or levels of contamination; and (iii) model systems investigating changes of temperature (land, air, water systems), acute whether events, carbon dioxide, and water system level rises on toxin production. Such methods could include measures of contamination, models of prediction, or biomonitoring. Climate models of changes in distribution of toxins are particularly welcome, as are publications that raise issues over changes in physiology/ecology of the producing organisms, for example changes in sexual reproduction in fungal species and the potential consequence. Submissions on mitigation efforts to restrict key exposures that address concerns of climate change in their approaches will be accepted.

All areas of natural toxins from fungal, algal, and plants are of interest. Traditional high risk toxins (e.g. Fungal: aflatoxins, fumonisins, deoxynivalenol, ochratoxin, zearalenone, citrinin, cyclopiazonic acid, ergot and patulin; Algal: ciguatoxin, saxitoxins, okadaic acids, dinophysistoxins, brevetoxins, domoic acid, azaparacids, scrombotoxins, tetrodotoxins; Plant: alkaloids, phytohemagglutinin, grayanotoxins, cyanogenic glycosides) will be considered for this Special Issue; we are also interested in novel or emerging toxins in all classes.

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 double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions 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 2400 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.

In response to global warming, an increase in cyanobacterial blooms is expected. In this work, the response of two native species of Planktothrix agardhii and Aphanizomenon gracile, as well as the response of two species alien to Europe—Chrysosporum bergii and Sphaerospermopsis [...] Read more.
In response to global warming, an increase in cyanobacterial blooms is expected. In this work, the response of two native species of Planktothrix agardhii and Aphanizomenon gracile, as well as the response of two species alien to Europe—Chrysosporum bergii and Sphaerospermopsis aphanizomenoides—to gradual temperature increase was tested. The northernmost point of alien species distribution in the European continent was recorded. The tested strains of native species were favoured at 20–28 °C. Alien species acted differently along temperature gradient and their growth rate was higher than native species. Temperature range of optimal growth rate for S. aphanizomenoides was similar to native species, while C. bergii was favoured at 26–30 °C but sensitive at 18–20 °C. Under all tested temperatures, non-toxic strains of the native cyanobacteria species prevailed over the toxic ones. In P. agardhii, the decrease in concentration of microcystins and other oligopeptides with the increasing temperature was related to higher growth rate. However, changes in saxitoxin concentration in A. gracile under different temperatures were not detected. Accommodating climate change perspectives, the current work showed a high necessity of further studies of temperature effect on distribution and toxicity of both native and alien cyanobacterial species.
