Special Issue "Aquatic Microbial Ecotoxicology"
A special issue of Environments (ISSN 2076-3298).
Deadline for manuscript submissions: closed (15 July 2019).
The management, protection and rehabilitation of freshwater and marine ecosystems are central environmental concerns on a global scale. In particular, water managers must deal with rapid population growth and urban development, as well as with their associated consequences. Aquatic environments worldwide are under multi-stressor pressures, the effects of which are expected to be exacerbated in the context of climate change. Continental waters are continuously under multiple stresses from anthropogenic sources (mixtures of contaminants, nutrients, salts, suspended solids, etc.), which degrade their chemical, physical and biological integrities. Marine environments are the ultimate receptacle for in-land waters, and, despite strong dilution potential, have been showing multiple signs of degradation.
The assessment of aquatic ecosystem health and integrity poses a major challenge because multiple anthropic stressors act cumulatively, and possibly synergistically, in addition to fluctuating in space and time. Traditional water quality monitoring does not necessarily reflect bioavailability, and does not inform on the effects of stressors on biota. Alternatively, biological assessment is an integrative approach increasingly included in water quality management protocols. Evaluating and understanding the response of living organisms subjected to environmental pressures provides insight on the real effects of ecosystem degradation on biota. Microorganism response is of particular interest, as microorganisms respond quickly to changes in their environments due to their position at the base of the trophic chain. These effects observed on microorganisms are therefore the starting points for a myriad of consequences cascading to higher trophic levels. One advantage of incorporating microorganism response in ecotoxicology is that microorganisms are always present in all types of conditions and they are particularly diverse in terms of functional groups and taxonomy. Multiple aspects of microorganism response therefore can provide information on water quality, e.g., taxonomy, functions (recycling, photosynthesis), traits, biomarkers, genetic expression, diversity, etc. A response to a perturbation or to multiple stressors can usually be observed despite confounding natural environmental factors.
This Special Issue invites critical reviews and research papers providing innovative insights into the effects of contaminants on freshwater and marine microorganisms. The focus of this Special Issue includes the following topics:
(i) a more realistic characterization of microorganism exposure to contaminants;
(ii) novel biomarkers or toxicity endpoints;
(iii) ecotoxicological responses at the individual, population and community levels;
(iv) structural and functional impacts of contaminants on aquatic microorganisms;
(v) effects of multiple stressors in a context of global change;
(vi) other topics related to microbial toxicology.

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 papers will be 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. Environments 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 1000 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.
