Forty years after the identification of Dinophysis fortii as the causative agent of severe gastrointestinal outbreaks in Japan, toxins produced by a few species of Dinophysis are recognized, in terms of persistence and distribution, as the main threat to intensive bivalve shellfish exploitations. Recently, Dinophysis events have emerged in traditionally “DSP-toxin free” areas (e.g., Eastern and Northwestern USA, the Pacific coast of Mexico, South China Sea). Increased regulation may explain certain cases, but some models include Dinophysis as a potential winner in global warming scenarios. Large differences in toxin profile and toxin content have been found between strains of the same species in the same location, but a “Dinophysis trigger level” based on cell densities is still widely used in monitoring systems. Different toxins from Dinophysis cells/fragments, their grazers, and detritus derived from fecal pellets are ingested by shellfish, affecting their absorption, transformation and elimination in a species-specific manner. All these processes, which play key roles in the impact of toxic outbreaks on shellfish resources, are poorly known, in particular from a metabolic and genomic point of view. Further, the direct effects of Dinophysis toxins on the growth and survival of shellfish species feeding on them have received little attention.
In this Special Issue, we welcome papers based on field studies on distribution of Dinophysis species and related events and their intensification (or decline) in monitored areas; sampling strategies and regulation; mechanisms and kinetics of uptake and detoxification in shellfish feeders and impact of different species/toxin profiles on different shellfish resources and on the shellfish physiology itself.

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 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.
