Toxic marine phytoplankton, zooplankton grazers, and pelagic food webs

TLDR
In most interactions of toxic phytoplankters with grazers and other marine food-web components, outcomes are situation-specific, and extrapolation of results from one set of circumstances to another may be inappropriate.
Abstract
Interactions between toxic phytoplankton and their zooplankton grazers are complex. Some zooplankters ingest some toxic phytoplankters with no apparent harm, whereas others are deleteriously affected. Phycotoxins vary in their modes of action, levels of toxicity and solubility, and affect grazers in different ways. Beyond effects on direct grazers, toxins may accumulate in and be transferred through marine food webs, affecting consumers at higher trophic levels, including fish, seabirds, and marine mammals. Grazers of toxic phytoplankton include protists as well as metazoans, and the impact of zooplankton grazing on development or termination of toxic blooms is poorly understood. In most interactions of toxic phytoplankters with grazers and other marine food-web components, outcomes are situation-specific, and extrapolation of results from one set of circumstances to another may be inappropriate.

Harmful cyanobacterial blooms: causes, consequences, and controls.

TL;DR: In this article, the applicability and feasibility of various controls and management approaches for natural waters and drinking water supplies are discussed, and a key underlying approach that should be considered in almost all instances is nutrient (both N and P) input reductions; which have been shown to effectively reduce cyanobacterial biomass, and therefore limit health risks and frequencies of hypoxic events.

Harmful algal blooms: Their ecophysiology and general relevance to phytoplankton blooms in the sea

TL;DR: HAB flagellates exhibit significant ecophysiological differences when compared to diatoms, including greater biophysical vulnerability to turbulence, greater bloom dependence on water-mass stratification, greater nutritional diversity involving mixotrophic tendencies, greater potential use of allelochemical mechanisms in interspecific competition and antipredation defenses, and unique behaviorial consequences of their motility.

Nuisance phytoplankton blooms in coastal, estuarine, and inland waters1

TL;DR: In this paper, the authors identify and address general applicable criteria for deeming a water body “bloom sensitive” and incorporate such criteria into the design of water quality management strategies applicable to both coastal marine and freshwater habitats.
