“…Monitoring and management programs are usually more systematic in high risk source waters, and increasingly, include cyanotoxins (e.g. Graham et al, 2008Graham et al, , 2012Hobson et al, 2010). In South Australian reservoirs, for example, the planktonic odor and toxin producing cyanobacterium Dolichospermum circinale is most likely to cause T&O issues during the warmer months from October to April, while in the River Murray, a lentic system, odorous planktonic populations of Dolichospermum, Pseudanabaena and Planktothrix can persist from summer into early winter under conditions of low flow and decreasing water temperatures.…”

“…Modeling has also been used to predict T&O and relate outbreaks to environmental parameters and in some cases, cyanobacteria (Smith et al, 2002;Davies et al, 2004;Dzialowski et al, 2009;Graham et al, 2008;Parinet et al, 2013;Su et al, 2015;). Yet despite the substantial costs that cyanobacterialderived and other T&O events impart on drinking water and other industries, there are few guidelines or standards for acceptable odor levels in drinking water and this issue is most often managed in a reactive mode.…”

“…For example, the physical transport of dissolved and particulate geosmin and 2-MIB by large scale down-welling events or river transport played major roles in T&O events affecting millions of consumers in Tokyo, Toronto and the Kansas River drainage (Hosaka et al, 1995;Rao et al, 2003;Graham et al, 2008Graham et al, , 2012. This spatial and temporal complexity has limited our ability to source-track and control T&O events using broad scale empirical data to infer sources and drivers, and as with other harmful metabolites, more effective prediction and control requires a more polyphasic approach that combines this ecosystem-level knowledge with the ecophysiology and expression and production of geosmin and 2-MIB (e.g.…”

“…Recent investigations suggest that picocyanobacterium Synechococcus sp. synthesize 2-methylisoborneol (MIB) and geosmin (1,2,7,7-tetramethyl-2-norbomeol) (GSM) [ 79 , 83 , 84 ]. It was also demonstrated that MIB is produced and secreted during cyanobacterial cell cycle, while GSM is released only after cells’ death.…”

Picocyanobacteria are extremely important organisms in the world's oceans and freshwater ecosystems. They play an essential role in primary production and their domination in phytoplankton biomass is common in both oligotrophic and eutrophic waters. Their role is expected to become even more relevant with the effect of climate change. However, this group of photoautotrophic organisms still remains insufficiently recognized. Only a few works have focused in detail on the occurrence of massive blooms of picocyanobacteria, their toxicity and allelopathic activity. Filling the gap in our knowledge about the mechanisms involved in the proliferation of these organisms could provide a better understanding of aquatic environments. In this review, we gathered and described recent information about allelopathic activity of picocyanobacteria and occurrence of their massive blooms in many aquatic ecosystems. We also examined the relationships between climate change and representative picocyanobacterial genera from freshwater, brackish and marine ecosystems. This work emphasizes the importance of studying the smallest picoplanktonic fractions of cyanobacteria.Keywords: allelopathy; allelochemicals; climate change; cyanotoxins; picocyanobacteria; picoplankton; blooms; secondary metabolites Key Contribution: We have updated a review of the literature dealing with allelopathic activity of picocyanobacteria; their toxicity; occurrence of their massive blooms and the relationships between climate change and representative picocyanobacterial genera from aquatic ecosystems.

“…In a summary report for the 2008–2009 state legislature, the top three toxic cyanobacteria genera in Washington lakes were identified as Anabaena , Aphanizomenon , and Microcystis [ 69 ]. Gloeotrichia was also included because a recent study confirmed microcystin-LR production by Gloeotrichia echinulata [ 70 ], and exposure to this genus has led to reports of human health impacts in Washington lakes.…”

The more frequent occurrence of both marine and freshwater toxic algal blooms and recent problems with new toxic events have increased the risk for illness and negatively impacted sustainable public access to safe shellfish and recreational waters in Washington State. Marine toxins that affect safe shellfish harvest in the state are the saxitoxins that cause paralytic shellfish poisoning (PSP), domoic acid that causes amnesic shellfish poisoning (ASP) and the first ever US closure in 2011 due to diarrhetic shellfish toxins that cause diarrhetic shellfish poisoning (DSP). Likewise, the freshwater toxins microcystins, anatoxin-a, cylindrospermopsins, and saxitoxins have been measured in state lakes, although cylindrospermopsins have not yet been measured above state regulatory guidance levels. This increased incidence of harmful algal blooms (HABs) has necessitated the partnering of state regulatory programs with citizen and user-fee sponsored monitoring efforts such as SoundToxins, the Olympic Region Harmful Algal Bloom (ORHAB) partnership and the state’s freshwater harmful algal bloom passive (opportunistic) surveillance program that allow citizens to share their observations with scientists. Through such integrated programs that provide an effective interface between formalized state and federal programs and observations by the general public, county staff and trained citizen volunteers, the best possible early warning systems can be instituted for surveillance of known HABs, as well as for the reporting and diagnosis of unusual events that may impact the future health of oceans, lakes, wildlife, and humans.
