Dinoflagellates and other microalgae can produce a wide spectrum of toxic molecules, which are the main responsible of shellfish poisoning syndromes. During seasonal harmful algal blooms (HABs), many filter-feeding marine invertebrates, including bivalve molluscs, can accumulate phycotoxins at extremely high levels, thus representing a serious threat to human health. Furthermore, HABs also have...

Harmful algal blooms (HABs) have been documented along the coasts of India and the ill effects felt by society at large. Most of these reports are from the Arabian Sea, west coast of India, whereas its counterpart, the Bay of Bengal (BOB), has remained unexplored in this context. The unique characteristic features of the BOB, such as large amount of riverine fresh water discharges, monsoonal cl...

Ladder polyether natural products are a class of natural products denoted by their high functional-group density and large number of well-defined stereocenters. They comprise the toxic component of harmful algal blooms (HABs), having significant negative economic and environmental ramifications. However, their mode of action, namely blocking various cellular ion channels, also denotes their pro...

Abstract Harmful algal blooms (HABs) pose a potential risk to human and ecosystem health. HAB occurrences are influenced by numerous environmental factors; thus, accurate predictions of HABs explanations about the required implement preventive water quality management. In this study, machine learning (ML) algorithms, i.e., random forest (RF) extreme gradient boosting (XGB), were employed predic...

Abstract Flow-regulated discharges of water from control structures into estuaries result in hydrologic and chemistry conditions that impact spatial temporal variability the structure biomass phytoplankton communities, including potential for harmful algal blooms (HABs). The relationships between regulated Caloosahatchee River (i.e., C-43 Canal) communities Estuary adjacent nearshore regions on...

Abstract. The western basin of Lake Erie has a history recurrent cyanobacterial harmful algal blooms (HABs) despite decades efforts by the United States and Canada to limit phosphorus loading, major driver blooms. In response, National Oceanic Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL) Cooperative Institute for (CIGLR) created an annual sampling prog...

We present an on-line early warning system that is operational in Scottish coastal waters to minimize the risk humans and aquaculture businesses terms of human health economic impacts harmful algal blooms (HABs) their associated biotoxins. The includes both map time-series based visualization tools. A “traffic light” index approach used highlight locations at elevated HAB/biotoxin risk. High re...

Dinoflagellates are essential components in marine ecosystems, and they possess two dissimilar flagella to facilitate movement. Dinoflagellates are major components of marine food webs and of extreme importance in balancing the ecosystem energy flux in oceans. They have been reported to be the primary cause of harmful algae bloom (HABs) events around the world, causing seafood poisoning and the...

Harmful algal blooms (HABs) cause a variety of deleterious effects on aquatic ecosystems, especially the toxic dinoflagellate Alexandrium tamarense, which poses a serious threat to marine economic and human health based on releasing paralytic shellfish poison into the environment. The algicidal bacterium Deinococcus sp. Y35 which can induce growth inhibition on A. tamarense was used to investig...
