Harmful cyanobacterial blooms have caused several problems in freshwater environments due to their prolific growth and the harmful cyanotoxins produced by some species. The occurrence of these organisms has increased in recent decades due to climate change and eutrophication, although most studies are from temperate regions in the Northern hemisphere. This review presents data about cyanobacteria occurrence, dominance, and toxicity events in freshwater bodies in a semiarid region of Northeast Brazil, in the tropical Southern hemisphere. We performed a literature survey of cyanobacteria publications from 1930 to 2016. We made a list of all the dominant species registered in each state, noted their distribution and occurrence of dominance events involving one or more species, and the registered records of toxic blooms, including information about the toxins involved and the range of values. We selected 102 publications that described cyanobacteria occurrence from states in Northeast Brazil; these publications included relevant contributions regarding cyanobacteria distribution, richness, density, and biomass. Forty-nine dominant species were recorded, with the most representation found in the state of Pernambuco (30 spp.). The genera with the highest occurrences were Microcystis, Cylindrospermopsis, Planktothrix, Dolichospermum (= Anabaena), and Geitlerinema, especially the species Cylindrospermopsis raciborskii, Microcystis aeruginosa, and Planktothrix agardhii. Episodes of toxic blooms were observed in four states. Microcystins, cylindrospermopsin, saxitoxins, and anatoxin-a(S) were found to be associated with these blooms. In Northeast Brazil, harmful cyanobacterial blooms are common in urban and public reservoirs. However, in recent years, cyanobacterial blooms in this region have been more intense and perennial, with high biomass occurring throughout the year.

Toxic Diatom Pseudo-nitzschia and Its Primary Consumers (Vectors) Bargu, Sibel; Smith, Emily; Özhan, Koray (Springer, Dordrecht, 2011-01-01) Toxic algal blooms are occurring on a more frequent basis and have been shown to cause harm in higher trophic levels. The diatom toxin domoic acid, produced by the genus Pseudo-nitzschia, has been shown to be responsible for the contamination of shellfish, zooplankton, and fish around the world. Contaminations have impacted various economical markets as well. These primary consumers (vectors) have a variety of responses to blooms of toxic phytoplankton species ranging from avoidance to ingestion of the alga...
Ecological impacts of freshwater algal blooms on water quality, plankton biodiversity, structure, and ecosystem functioning Alves Amorım, Cıhelıo; Moura, Ariadne do Nascimento (2021-03-01) Harmful algal blooms are among the emerging threats to freshwater biodiversity that need to be studied further in the Anthropocene. Here, we studied freshwater plankton communities in ten tropical reservoirs to record the impact of algal blooms, comprising different phytoplankton taxa, on water quality, plankton biodiversity, and ecosystem functioning. We compared water quality parameters (water transparency, mixing depth, pH, electrical conductivity, dissolved inorganic nitrogen, total dissolved phosphorus...
Seasonal variations of morpho-functional phytoplankton groups influence the top-down control of a cladoceran in a tropical hypereutrophic lake Alves Amorım, Cıhelıo; Valenca, Celina Rebeca; de Moura-Falcao, Rafael Henrique; Moura, Ariadne do Nascimento (2019-09-01) Shallow lakes are often affected by the increase in nutrients and global climate change, with frequent occurrences of cyanobacterial blooms. In this context, the biomanipulation of the higher trophic levels, such as zooplankton, can efficiently control these blooms. Based on this, this study aimed to verify the potential of a medium-sized cladoceran, Macrothrix spinosa, to control the phytoplankton biomass from the Apipucos reservoir, a shallow tropical hypereutrophic lake. For this, grazing experiments wer...
Biometric and physiological responses of Egeria densa Planch. cultivated with toxic and non-toxic strains of Microcystis Alves Amorım, Cıhelıo; Ulisses, Claudia; Moura, Ariadne Nascimento (2017-10-01) Cyanobacterial blooms are becoming increasingly common in aquatic environments around the world, mainly due to eutrophication and climate change. Cyanotoxin-producing strains (e.g., microcystins (MC) producers) may be present in these blooms, affecting the growth of other aquatic organisms, such as aquatic macrophytes. In this study, we evaluated the morphometric and physiological responses of the aquatic macrophyte Egeria densa to the exposure to a toxic strain of Microcystis aeruginosa (MCs producer) and ...
Operational control on environmental safety of potentially toxic elements during thermal conversion of metal-accumulator invasive ragweed to biochar Yousaf, Balal; Liu, Guijian; Abbas, Qumber; Ali, Muhammad Ubaid; Wang, Ruwei; Ahmed, Rafay; Wang, Chengming; Al-Wabel, Mohammad I.; Usman, Adel R. A. (2018-09-01) Ragweed (Ambrosia artemisiifolia L), a metal-accumulator invasive species, was pyrolyzed under a range of pyrolytic conditions to investigate their influence on immobilization and environmental safety of potentially toxic elements (PTEs) in the produced biochar. Conditions tested included temperature, retention time, heating rate, gas flow rate and particle size. Temperature and particle size had pronounced effects on product yields and physico-chemical characteristics of the produced biochar. All PTEs were...
