SETAC Europe 2020 Session: Marine and Freshwater Pelagic and Benthic Harmful Algal Blooms

SETAC Europe 30th Annual meeting will take place on 3-7 May 2020 in Dublin, Ireland.

A Session on “Marine and Freshwater Pelagic and Benthic Harmful Algal Blooms: Toxins Production, Detection, Fate, Effects, Monitoring and Management” (Co-chairs Triantafyllos Kaloudis, James Lazorchack) is scheduled under “Track 6”. 

You can submit your abstracts by 27 November 2019.

Description:

Harmful algal blooms (HABs) in freshwater and marine systems are defined as an assemblage of eukaryotic or prokaryotic plankton which have the potential to cause negative health, ecological or economic impacts. These negative impacts are caused by mechanisms that include, but are not limited to, public health and environmental risks from toxin(s) production, light attenuation, diurnal swings in pH and dissolved oxygen, offensive tastes and odors, and impaired visual aesthetics. Examples of some of the major toxins found in various combinations are: (a) prokaryotes (cyanobacteria) – microcystins, cylindrospermopsins, anatoxins, nodularin and saxitoxins; and (b) eukaryotes (dinoflagellates, diatoms, chrysophytes and raphidophytes) euglenophysins, prymensins, brevetoxins, ciguatoxins, saxitoxins and domoic acid. In recent years, there has been new information about the potential threat of benthic (attached and/or buried) toxin-producing cyanobacteria and algae. However, there are still many uncertainties about planktonic and benthic cyanobacteria/algae and the nature of their benthic/pelagic life stages. There is also some uncertainty concerning whether there is a greater risk to aquatic life due to the effects of filamentous and matt forming toxin and non-toxin producing algae on feeding inhibition and smothering. What are the current knowledge gaps related to blooms of benthic cyanobacteria/algae on substrates (attached) and/or in sediment (buried)? What research is required to address these gaps? Do we have enough knowledge to develop mitigation plans and predictive models? What tools are available to track and monitor benthic cyanobacteria/algae and their associated toxins in freshwater and marine environments, and are these fit for purpose? What information do we need to make informed risk assessments and are our current tools/techniques sufficient? How should we best incorporate ‘omics techniques into benthic cyanobacterial/algal research? What are the risks of filamentous of matt forming cyanobacteria and algae? What are the current regulations available to address both benthic and pelagic HABS and what are the current difficulties in managing the conditions that contribute to toxin production? To help address these questions, the objective of this session is to exchange information on the distribution, detection, identification, , occurrence and interaction of both benthic and planktonic cyanobacteria and algae and their associated toxins and finally management tools or approaches to reduce occurrence of blooms.

Special Issue “Potentially Toxic Benthic Microorganisms in Freshwater and Marine Ecosystems”

Dr. Philipp Hess (Ifremer, France) and Dr. Jean-Francois Humbert (Sorbonne University, France) are editors of a Special Issue titled “Potentially Toxic Benthic Microorganisms in Freshwater and Marine Ecosystems”, in Toxins (MDPI). This special issue belongs to the section “Marine and Freshwater Toxins“.
The aim of the  Special Issue is to “gather the most recent research on benthic cyanobacteria and microalgae proliferating in marine and freshwater ecosystems and on their toxins. All papers dealing with the taxonomy, genetic diversity, ecology and toxicity of biofilms dominated by potentially-toxic cyanobacteria and microalgae and on risk assessment and management associated with such assemblages will be considered in this Special Issue.
The deadline for manuscript submissions is 31 August 2019, but papers will be published as soon as they are accepted following peer-review, i.e. well before the deadline and typically within 4-8 weeks from submission. 
Information about manuscript submission for this Special Issue can be found in the Issue’s webpage.
You can share this information with colleagues that may be interested to publish in this Special Issue.

CyanoSED: A Workshop on Benthic Cyanobacteria and Cyanotoxins, August 6 & 7, in Cincinnati, Ohio.

On August 6 and 7, 2018, CyanoSED: A Workshop on Benthic Cyanobacteria and Cyanotoxins will take place at EPA-Cincinnati.

The workshop is organized by Dr. Kaytee Pokrzywinski (U.S. Army Corps of Engineers), Dr. Timothy Davis (Bowling Green State University), Dr. Susie Wood (The Cawthron Institute) and Dr. Jim Lazorchak (EPA, ORD, NERL).

The goals of the workshop are to identify knowledge gaps and prioritize research needs on issues surrounding benthic cyanobacteria and it will feature presentations from experts in the field and discussions on those presented topics.

 Symposium Objectives:

  1. Understand current research in benthic/sediment-associated HABs related to benthic mat-forming (including attached, periphytic and filamentous) cyanobacteria and benthic-pelagic (planktonic) coupling of bloom events.
  2. Identify knowledge gaps and topic areas worth pursing in more detail.
  3. Facilitate engagement among federal, local and state government agencies; academic institutions; and industry partners to continue coordination and collaboration on sediment/benthic-associated HABs issues.
  4. Effectively disseminate workshop results by facilitating publication of research priorities and detailed key discussions developed through this workshop.
