“…Metal concentrations in both water and sediment were lower than those found in previous works in the lower basin of the Salado River and Colastiné-Corralito stream system (Frau et al, 2020;Gagneten & Paggi, 2009;Gagneten et al, 2007;José de Paggi & Devercelli, 2011;Regaldo et al, 2017). According to results obtained in this work, Cr and Pb maximum concentrations in water were 5.67 μg/L and 15.3 μg/L, respectively), surpassing AEQG proposed for the protection of the aquatic biota in 37.5% and 31.3% of the samples, respectively.…”

“…Because of their short life cycles, they respond quickly to environmental fluctuations of natural or anthropic origin (Parmar et al, 2016). The relationship between land use and plankton diversity has been explored in streams, lakes, and rivers of Central East Argentina (Frau et al, 2020;Gagneten & Paggi, 2009; José de Paggi & Devercelli, 2011), but urban aquatic systems remain poorly studied in Argentina and other countries (Kozak et al, 2017;Perbiche-Neves et al, 2013).…”

parameters, nutrients, chemical oxygen demand (COD), biological oxygen demand (BOD 5 ), and concentrations of potentially toxic metals (Cu, Cr, Pb, and Cd) in water and benthic sediments were analyzed in four sampling sites. The heavy metal geo-accumulation index (Igeo) was also calculated. Quali-quantitative analysis of phytoplankton and zooplankton samples was performed and summarized in ecological attributes and indices: Total density, specific richness, Shannon's diversity index, Simpsons' dominance index, and evenness index, as well as phytoplanktonic biovolume and functional groups. Except Cu, metal concentrations in water exceeded recommended limits for freshwaters in 37.5% (Cr), 31.3% (Pb), and 18.8% (Cd) of samples. Igeo revealed that sediments were moderately, highly, and very seriously polluted with Cu, Cr, and Pb, respectively. Phytoplankton showed the predominance of functional groups typical of eutrophic and low-flow environments, with high concentrations of nutrients. Cyanobacterial blooms occurred in 75% of the samples, considered high-risk events for the aquatic life and users of the urban reserve. The zooplankton community was dominated by microzooplankton, characterized by smaller species, more tolerant to polluted and eutrophic waters. This survey evidences the urgent need to develop a comprehensive management plan for the area.

“…L. quadridentata was highly resistant to DDT and less susceptible to Mn than the cladocerans D. magna [165]. José de Paggi and Devercelli [193] examined the influence of watershed land use on microzooplankton around the city of Santa Fe in Argentina. Six rivers and a shallow lake located in rural and urban areas were sampled during 4 weeks.…”

An important objective of aquatic ecotoxicology is to determine the effects of toxic compounds in organisms that play a central role in aquatic communities where rotifers have a large impact on several important ecological processes. The contribution of the rotifers to secondary production in many aquatic communities is substantial as they are often the larger fraction of zooplankton biomass at certain times of the year. In addition to the importance of their ecological roles in aquatic communities, the rotifers are attractive organisms for ecotoxicological studies by its short life cycles and rapid reproduction, their small size, and little volumes needed for culture and toxicity assays. The main end points used in ecotoxicological studies are mortality, reproduction, behavior, and biomarkers. Such parameters are included in international regulations from all over the world, where different species are used to evaluate the effect of environmental samples or chemical compounds. The high diversity of rotifers is an important issue because it can modify their relative susceptibility to toxicants. Thus, more studies are needed to know the relations and mechanisms involved in clonal variation, sensitivity, and development, which can be all assessed by state-of-the-art procedures.

“…Essa distribuição está associada asseveros custos e benefícios, como a ocorrência da predação, alimentação ótima e condições ambientais (IGLESIAS et al, 2007). Essas interações podem estruturar as comunidades locais (COTTENIE et al, 2003) como de rotíferos, especialmente em lagos ( JOSÉ DE PAGGI;DEVERCELLI, 2011), igarapés e tanques de piscicultura.…”

ResumoOs rotíferos são organismos microscópicos e representam um dos mais importantes grupos da comunidade zooplanctônica, não apenas pela riqueza de espécies, mas também pela abundância dos organismos. A situação hipotética para a realização desta pesquisa consiste em verificar se a distribuição espacial da comunidade de rotíferos é heterogênea e se há diversidade de organismos em tanques de piscicultura em Cruzeiro do Sul. Os tanques selecionados foram agrupados, considerando o zooplâncton, através da análise de cluster utilizando dissimilaridade, e ainda sobre a comunidade foram aplicados também os índices de diversidade e riqueza. Os resultados não revelaram agrupamento significativo para os tanques; cada sistema apresentou sua peculiaridade.Palavras-chave: riqueza; zooplâncton; aquicultura. AbstractRotifers are microscopic organisms that present themselves as one of most significant groups of the zooplankton community, not only by species richness, but also by the numerical abundance. A hypothetical situation for this research is whether the spatial distribution of the rotifer community in fishponds is heterogeneous and has organism's diversity in Cruzeiro do Sul is heterogeneous. The selected tanks were grouped, considering the zooplankton by cluster analysis using dissimilarity multivariate analysis, as well as on the community has been applied also the diversity and richness indexes. The results revealed no significant clustering for tanks, with each system its peculiarity.
