Chapter 33: Cyanobacteria blooms: effects on aquatic ecosystems
نویسنده
چکیده
Lakes, rivers and estuaries that experience frequent and/or prolonged blooms of cyanobacteria display an array of ecosystem properties that may have impacts on water quality, biological communities and ecosystem services. Some impacts of blooms may be direct, including possible effects of toxins on fish, invertebrates, and other aquatic fauna, or indirect, including: a reduction of submerged plants when plankton biomass becomes very high; and changes in fish community structure if summer cold water refuges are lost due to hypolimnetic anoxia. This paper is a concise overview of cyanobacteria blooms, focusing on their relationship to trophic state, their temporal dynamics, and their potential impacts on ecosystem structure and function.

Chapter 5: Toxic Cyanobacteria in Florida Waters
Cyanobacteria represent a common component of algal assemblages in Florida's lakes, springs, estuaries, and other marine environments. The frequency of cyanobacterial bloom reports has recently become more common and algal toxin data are just beginning to be collected with the advent of monitoring efforts and the availability of laboratories in the state capable of conducting algal toxin analys...

Eutrophication process and, more recently, global warming have been considered major factors in disturbing aquatic ecosystems dynamics, leading to a shift in plankton communities and to the dominance of cyanobacteria worldwide [1]. As a consequence of cyanobacterial blooms, the impairment of water quality has lead to high costs in economy, mainly due to losses in fisheries and tourism industrie...

Cyanobacteria are ecologically one of the most prolific groups of phototrophic prokaryotes in both marine and freshwater habitats. Both the beneficial and detrimental aspects of cyanobacteria are of considerable significance. They are important primary producers as well as an immense source of several secondary products, including an array of toxic compounds known as cyanotoxins. Abundant growt...

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 rema...

Cyanobacteria or blue-green algae are among the pioneer organisms of planet Earth. They developed an efficient photosynthetic capacity and played a significant role in the evolution of the early atmosphere. Essential for the development and evolution of species, they proliferate easily in aquatic environments, primarily due to human activities. Eutrophic environments are conducive to the appear...
