Analysis of the phytoplankton community emphasizing cyanobacteria in four cascade reservoirs system of the Iguazu River, Paraná, Brazil

Abstract: Knowing the ecological changes in a reservoir is of great relevance to study environmental impacts and assess water quality. Among these studies, the knowledge about the structure of the phytoplankton community is essential, once they represent a fundamental component of aquatic ecosystems, responding immediately to physical and chemical alterations in water. The objective of this work was to analyze the phytoplankton community and the influence of abiotic factors, along the longitudinal axis in four cascade r… Show more

“…Reports of cyanobacterial blooms in oligo-mesotrophic reservoirs are not uncommon (Brito, Maia-Barbosa & Pinto-Coelho, 2011;Su et al, 2019). Some previous studies in the SS and SO reservoirs have also recorded large abundances of cyanobacteria in the phytoplankton (Adloff et al, 2018;Bortolini et al, 2018). The filaments or mucilages of these algae directly interfere with the filtration apparatuses of large cladocerans and calanoid copepods, which leads to the decline and replacement of these populations by small rotifers and cladocerans (Sendacz, Caleffi & Santos-Soares, 2006;Eskinazi-Sant'Anna et al, 2013;Perbiche-Neves et al, 2016).…”

“…En ellos, el agua enriquecida en nutrientes que corre en los ríos es retenida, generando condiciones que favorecen la acumulación de cianobacterias de gran tamaño y la ocurrencia de floraciones (Wang, et al, 2018). En estas condiciones, las cianobacterias del CMA son las más frecuentes (Reynolds, et al, 2002;Debastiani, et al, 2016;Haakonsson, et al, 2017;Adloff, et al, 2018;González-Piana, et al, 2017). Esto transforma a los embalses en fuentes potenciales de cianobacterias, que en condiciones de lluvias muy intensas pueden ser transportadas aguas abajo, distribuyendo las grandes biomasas o inoculando nuevos ecosistemas (Anderson, et al, 2018).…”

“…Los embalses y los cuerpos de agua que registran más floraciones en la Cuenca del Plata, en particular en el área de influencia de la costa de Uruguay, son aquellos cuyas cuencas de drenaje incluyen una producción agrícola intensiva (Aguilera, et al, 2018;Debastiani et al, 2016). Este es el caso de los embalses en los tributarios del Plata, como por ejemplo el río Uruguay (Salto Grande: Bordet, et al, 2017), Río Negro (González-Piana, et al, 2017) y río Paraná (Adloff et al, 2018). Alternativamente, los remansos de los ríos, con adecuada temperatura, salinidad y luz, también pueden actuar como fuentes de desarrollo de organismos que, en función de variables hidrológicas y climáticas, podrían ser arrastrados hacia zonas con condiciones menos adecuadas para el crecimiento, como los ambientes estuarino-marinos.…”
