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.
The 19th International Conference on Harmful Algae will take place from the 11th to the 16th of October 2020 in La Paz, BCS, Mexico, being the 2nd ICHA conference held in Latin America. As the last conferences, the 2020 conference will include topics related with the understanding of the causes, evolution and impacts of harmful microalgae and cyanobacteria. We are planning an enjoyable meeting where scientists can present their research, share their ideas, establish new collaborations, and connect the science on harmful algae with the beneficiaries of this research.
La Paz is an ideal city for the meeting where many academic institutes are found. It is a small, secure and quiet city, with beautiful surroundings, which is visited by many international tourists and academics year round. The average temperature in October is between 21 and 34 °C.
For some countries a visa may be required. Please check visa regulations well in advance with your local Mexican Consulate for official instructions on the specific visa regulations and application procedures.
As the major host of the conference, ISSHA will support the event with various activities: Travel awards to students and post-docs, several achievement awards, and ISSHA auction.
Looking forward to seeing you in La Paz, Mexico!
The Organizing Committee,
Freshwater cyanobacteria are known to produce a suite of different chemicals that can be toxic to many organisms. These toxins can have adverse impacts on humans, animals, and even aquatic and terrestrial plants. Further information about cyanobacterial toxins is required to better understand and manage their risks in freshwater environments. This Special Issue aims to bring together papers that provide new information on the monitoring of cyanobacterial toxins and the identification of toxins in freshwater environments. Further, papers are invited that develop our knowledge of how cyanobacterial toxins impact humans, as well as different aquatic and terrestrial organisms. Papers that better develop our understanding of how toxin production by cyanobacteria is regulated are also welcomed.

Cyanobacterial blooms are a water quality problem that has been widely acknowledged to cause detrimental ecological and economic effects in drinking and recreational waters supplies, and fisheries. There is increasing evidence that cyanobacterial blooms have increased globally and are likely to expand in water resources due to climate change. Of most concern are cyanotoxins, along with mechanisms that induce their release and fate in the aquatic envirornment. These secondary metabolites pose a potential hazard to human health and agricultural and aquaculture products directed for animal and human consumption; therefore, strict and reliable control of cyanotoxins is crucial for assessing risk. In this direction, a deeper understanding of the mechanisms that determine cyanobacterial bloom structures and toxin production become a target for managing practices.This Special Issue aims to bring together recent research of multi- and interdisciplinary approaches from the field to the laboratory and back again, driven by working hypotheses based on any aspect from ecological theory to applied research on mitigating cyanobacterial blooms. Of special interest are papers that suggest the use of complementary approaches, from the most recently developed molecular-based methods to more classical approaches and experimental and mathematical modeling regarding factors (abiotic and/or biotic) that control the diversity of not only the key bloom forming cyanobacterial species, but also their interactions to other biota, either in frehswater systems or their adjacent habitats, and their role in preventing and/or promoting cyanobacterial growth and toxin production and/or degradation.

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”,
(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.
You can share this information with colleagues that may be interested to publish in this Special Issue.

A Session on “Ecology – Harmful Algae and Global Change” is organized by Gustaaf HALLEGRAEFF, Myriam BORMANS and Raffaele SIANO, within ICHA2018 in Nantes (21 to 26 October 2018).
Over the last few decades, an increase in frequency and intensity of harmful algal blooms as well as changes in the biogeography and in the temporal dynamics of species and functional groups have been associated to ecosystem variations of both natural and antropogenic origins. This session is focused on the observed and forecasted effects of the climate and of the human driven on the ecology of toxic cyanobacteria and eukaryotic microalgae. We welcome contributions using experimental analyses, in situ observations or model predictions which advance our understanding on the selection of harmful algae in a warmer and changing future. Studies which consider interactions between abiotic and/or biotic drivers on bloom development, composition and toxicity in the context of climate changes are particularly encouraged.
The deadline for abstract submission is 15 April 2018 !!!
