Cyanobacteria are the Earth’s oldest oxygenic photoautotrophs and have had major impacts on shaping its biosphere. Their long evolutionary history (∼3.5 by) has enabled them to adapt to geochemical and climatic changes, and more recently anthropogenic modifications of aquatic environments, including nutrient over-enrichment (eutrophication), water diversions, withdrawals, and salinization. Many cyanobacterial genera exhibit optimal growth rates and bloom potentials at relatively high water… 
Controlling harmful cyanobacterial blooms in a climatically more extreme world: management options and research needs
Cyanobacteria have a long evolutionary history that has been instrumental in allowing them to adapt to long-term geochemical and climatic changes, as well as current human and climatic alterations of
Mitigating Harmful Cyanobacterial Blooms in a Human- and Climatically-Impacted World
TLDR
Rising temperatures and greater hydrologic variability will increase growth rates and alter critical nutrient thresholds for CyanoHAB development; thus, nutrient reductions for bloom control may need to be more aggressively pursued in response to climatic changes globally.

TLDR
In order to ensure long‐term control of CyanoHABs, these strategies should be adaptive to climatic variability and change, because nutrient‐CyanoHab thresholds will likely be altered in a climatically more‐extreme world.
Dynamics of harmful cyanobacterial blooms and their toxins: environmental and human health perspectives and management strategies
TLDR
This chapter summarizes how, when, and why cyanotoxins occur; how to determine cyanOToxins if they occur in a given water source; toxicology mechanisms of major groups of cyanotOxins; what management and control procedures can reduce cyanotoxin production in source waters; and finally, what treatment strategies can prevent cyano-Hbs from reaching the public.
Freshwater Viruses: From Ecosystem Dynamics to the Cyanobacterial Cell
TLDR
Examination of viral ecology in two freshwater habitats in Australia and the Netherlands reveals a very high viral abundance in this reservoir system, which varied little spatially or temporally, and there were negative correlations between the abundances of viruses and individual cyanobacterial species.
Mitigating a global expansion of toxic cyanobacterial blooms: confounding effects and challenges posed by climate change
Managing and mitigating the global expansion of toxic cyanobacterial harmful algal blooms (CyanoHABs) is a major challenge facing researchers and water resource managers. Various approaches,
Harmful Algal Blooms
TLDR
While HABs are as diverse as the water bodies they impact, this chapter focuses on some specific examples of known HAB taxa that affect inland waters in North America and highlight some of the important strategies used by these species to enable their excessive growth.
