TLDR
It is shown that genotype × genotype interactions are important in explaining mortality in short‐time exposures of Daphnia to Microcystis, and may result in local coadaptation and a geographic mosaic of coevolution.
Abstract
Toxic algal blooms are an important problem worldwide The literature on toxic cyanobacteria blooms in inland waters reports widely divergent results on whether zooplankton can control cyanobacteria blooms or cyanobacteria suppress zooplankton by their toxins Here we test whether this may be due to genotype × genotype interactions, in which interactions between the large-bodied and efficient grazer Daphnia and the widespread cyanobacterium Microcystis are not only dependent on Microcystis strain or Daphnia genotype but are specific to genotype × genotype combinations We show that genotype × genotype interactions are important in explaining mortality in short-time exposures of Daphnia to Microcystis These genotype × genotype interactions may result in local coadaptation and a geographic mosaic of coevolution Genotype × genotype interactions can explain why the literature on zooplankton-cyanobacteria interactions is seemingly inconsistent, and provide hope that zooplankton can contribute to the suppression of cyanobacteria blooms in restoration projects

Harmful Algal Blooms

TL;DR: 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.

Colony formation in the cyanobacterium Microcystis

TL;DR: A systematic review of field studies from the 1990s to 2017 where Microcystis was detected as the dominant genus in waterbodies from temperate to subtropical and tropical zones finds colony formation by cell adhesion can be induced by zooplankton grazing, high Ca2+ concentration, and microcystins.

The interaction between cyanobacteria and zooplankton in a more eutrophic world.

TL;DR: This synthesis shows that longer exposure to cyanobacteria can shift zooplankton communities toward better-adapted species, select for more tolerant genotypes within a species, and induce traits within the lifetime of individual zoops, in turn affecting the function of bloom-dominated plankton ecosystems.

Global expansion of toxic and non-toxic cyanobacteria: effect on ecosystem functioning

TL;DR: The expansion of toxic and non-toxic cyanobacteria to a wide geographic range may have an impact on the ecosystems, trophic cascades and geochemical cycles, and on the diversity and complexity of the microbial community.

Perspective: Advancing the research agenda for improving understanding of cyanobacteria in a future of global change

TL;DR: A recent review as discussed by the authors advocates that to better predict and manage cyanoHABs in a changing world, researchers need to leverage studies undertaken to date, but adopt a more complex and definitive suite of experiments and models which can effectively capture the temporal scales of processes driven by eutrophication and a changing climate.

Toxic cyanobacteria in water: a guide to their public health consequences, monitoring and management.

TL;DR: The state of knowledge regarding the principal considerations in the design of programmes and studies for monitoring water resources and supplies and describes the approaches and procedures used as mentioned in this paper, and the information needed for protecting drinking water sources and recreational water bodies from the health hazards caused by cyanobacteria and their toxins.

Harmful Algal Blooms and Eutrophication: Nutrient Sources, Composition, and Consequences

TL;DR: The relationship between harmful algal blooms and eutrophication of coastal waters from human activities has been investigated in this paper, focusing on sources of nutrients, known effects of nutrient loading and reduction, new understanding of pathways of nutrient acquisition among HAB species, and relationships between nutrients and toxic algae.

Blooms like it hot

TL;DR: A link exists between global warming and the worldwide proliferation of harmful cyanobacterial blooms as discussed by the authors, and it has been shown that global warming can be linked with the proliferation of these blooms.

Carbon to volume relationships for dinoflagellates, diatoms, and other protist plankton

TL;DR: Cellular carbon and nitrogen content and cell volume of nutritionally and morphologically diverse dinoflagellate species were measured to determine carbon to volume and nitrogen to volume relationships.
