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 algae. To define their role in toxin transfer, it is necessary to know their position in the food web and their response to toxic food species. If the toxin is transferred via these vectors, it can cause a serious intoxication in humans, marine birds, and mammals.

Cyanobacterial blooms in freshwater bodies from a semiarid region, Northeast Brazil: A review Moura, Ariadne do Nascimento; Aragao-Tavares, Nisia K. C.; Alves Amorım, Cıhelıo (2018-01-01) 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...
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...
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...
Reproductive toxicity parameters and biological monitoring in occupationally and environmentally boron-exposed persons in BandA +/- rma, Turkey DUYDU, YALÇIN; Basaran, Nursen; ÜSTÜNDAĞ, AYLİN; AYDIN DİLSİZ, SEVTAP; ÜNDEĞER BUCURGAT, ÜLKÜ; Ataman, Osman Yavuz; AYDOS, KAAN; Duker, Yalcin; Ickstadt, Katja; Waltrup, Britta Schulze; Golka, Klaus; Bolt, Hermann M. (2011-06-01) Boric acid and sodium borates have been considered as being "toxic to reproduction and development", following results of animal studies with high doses. Experimentally, a NOAEL (no observed adverse effect level) of 17.5 mg B/kg-bw/day has been identified for the (male) reproductive effects of boron in a multigeneration study of rats, and a NOAEL for the developmental effects in rats was identified at 9.6 mg B/kg-bw/day. These values are being taken as the basis of current EU safety assessments. The present...
Warming Effects on Periphyton Community and Abundance in Different Seasons Are Influenced by Nutrient State and Plant Type: A Shallow Lake Mesocosm Study Hao, Beibei; Wu, Haoping; Zhen, Wei; Jo, Hyunbin; Cai, Yanpeng; Jeppesen, Erik; Li, Wei (Frontiers Media SA, 2020-4-9) Periphyton plays an important role in lake ecosystems processes, especially at low and intermediate nutrient levels where periphyton contribution to primary production can be similar to or exceed that of phytoplankton. Knowledge of how periphyton responds to key drivers such as climate change and nutrient enrichment is, therefore, crucial. We conducted a series of mesocosm experiments over four seasons to elucidate the responses of periphyton communities to nutrient (low and high, TN-0.33 mg L-1 TP-7.1 mu g...
