“…Recent years have seen renewed efforts to improve the efficiency of biological monitoring tools to assess water resources (Buss et al 2003, Czerniawska-Kusza 2005. The effective use of these tools requires a better understanding of the organisms that have the greatest influence on biotic index results, as well as of the processes that underlie the distribution and occurrence of bioindicator taxa in the environment.…”

“…Given this state of affairs, efficient assessments of water quality are a critical tool for managing water resources (Buss et al 2003). The most commonly used variables to monitor water quality at present include physical and chemical attributes (e.g., pH, conductivity, water temperature, current speed, streamflow, biochemical oxygen demand (BOD 5 ), chemical oxygen demand (COD), phosphate, nitrate, nitrite, and oils and grease) as well as biological attributes (e.g., benthonic macroinvertebrates, fish, algae, and bacteria).…”

“…In contrast, biological communities provide a more faithful reflection of environmental conditions, since they are continually exposed to them (Rosenberg & Resh 1993). As some groups of organisms are extremely sensitive to environmental conditions while others can survive in severely disturbed systems, aquatic communities are a good indicator of environmental quality (Buss et al 2003). …”

MENEZES, M.S. A comparative analysis of biotic indices that use macroinvertebrates to assess water quality in a coastal river of Paraná state, southern Brazil. Biota Neotrop. 11(4): http://www. biotaneotropica.org.br/v11n4/en/abstract?article+bn00411042011.Abstract: Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers and lakes. In Brazil water samples are mainly analyzed using physical and chemical attributes, because most biotic indices were developed in other countries and their effective application to Brazilian ecosystems requires significant research. This study compared four biotic indices commonly used to evaluate water quality via benthic macroinvertebrates in order to determine which index best reflects ecosystem health in a coastal river in Brazil's Paraná state. We also analyzed functional feeding groups. The indices studied were: 1) EPT (percent of Ephemeroptera, Plecoptera and Trichoptera); 2) BMWP' (Biological Monitoring Work Party System); 3) BMWP'-ASPT (Average Score per Taxon); and 4) HFBI (Hilsenhoff Family Biotic Index). All indices were calculated from five samples collected from April 2005 to April 2006 at two stations on the coastal do Pinto River. The river's headwaters are inside a protected area but impacts increase downriver (e.g., towns, cattle grazing, tourism). The HFBI index did the poorest job of reflecting water quality. No one index performed better than the others, and all indices yielded water quality scores that did not accurately reflect macroinvertebrate community structure because all of them had differences between ordination scores and the structure of assemblage. The functional feeding groups protocol classified the lower stretch of the river as disturbed due to human impacts, suggesting that this method is a good one to evaluate health in environments.

“…A utilização desses organismos vivos como ferramentas para o monitoramento de ambientes aquáticos serve para avaliar alterações ocorridas em locais que, geralmente, são atribuídas a ações antrópicas (BUSS et al, 2003). Nos sistemas aquáticos os insetos são apropriados para tal finalidade por serem diversos, apresentarem ciclo rápido e serem facilmente amostrados (SILVEIRA NETO et al,1995) Nesse contexto, comunidades bentônicas podem ser utilizadas como indicadores de qualidade de ambientes aquáticos, onde sua estabilidade e permanência são determinadas pelas condições do meio em que vivem (MENEGATT et al, 2007).…”

“…Os rios estão sujeitos a inúmeras perturbações e a biota aquática reage a esses estímulos, sejam naturais, sejam antrópicos (BUSS & NESSIMIAN, 2003). A detecção dos resultados dos impactos sobre os rios depende do uso de bioindicadores, combinados com variáveis físicas e químicas que regem o funcionamento dos ecossistemas (CALLISTO et al, 2004).…”

RESUMO: Com objetivo de caracterizar espacial e temporalmente os riachos da microbacia do rio São Francisco Verdadeiro, Marechal Cândido Rondon -PR, em função de fatores limnológicos, foram estabelecidas seis estações de coleta em três riachos (Curvado, Ajuricaba e Arroio Fundo), sendo uma estação na foz e outra na nascente. As coletas de água foram obtidas entre junho de 2005 e maio de 2006, totalizando 72 amostras. Foram analisadas as seguintes variáveis: temperatura, pH, condutividade elétrica, oxigênio dissolvido, turbidez, material em suspensão, fósforo total dissolvido, ortofosfato, nitrogênio total e nitrogênio amoniacal. De acordo com a análise de variância, houve baixa variabilidade entre as estações de coleta, porém a variação temporal demonstrou a influência do ciclo hidrológico. A análise de componentes principais (ACP) discriminou o sistema com base nos maiores valores registrados para as variáveis limnológicas, ficando separados os períodos influenciados pelas secas e pelas chuvas. A maior parte das variáveis está associada com o período de chuvas, no entanto há concentrações esporádicas de nutrientes na seca e menores valores de oxigênio dissolvido, demonstrando a dificuldade de diluição nesse período, causada pela diminuição da chuva e, consequentemente, do volume de água dos riachos. PALAVRAS-CHAVE:variáveis físicas e químicas, limnologia, material alóctone. SPATIAL AND TEMPORAL VARIATION I OF LIMNOLOGICAL FACTORS IN STREAMS OF THE MICRO-BASIN OF THE SÃO FRANCISCO VERDADEIRO RIVERABSTRACT: In order to characterize spatially and temporarily streams of the São Francisco Verdadeiro river micro-basin in Marechal Cândido Rondon, State of Paraná, Brazil, according to limnological factors, six sampling stations were established in three streams (Curvado, Ajuricaba and Arroio Fundo) -one station at the mouth of the river and other at the spring of the streams. Water samples were collected between June 2005 and May 2006, totalizing 72 samples. The following variables were analyzed: temperature, pH, electric conductivity, dissolved oxygen, turbidity, suspended matter, total dissolved phosphorus, orthophosphate, total nitrogen and amoniacal nitrogen. According to ANOVA (variance analysis) it was observed low variability among the sampling stations however the temporal variation demonstrated the influence of the hydrologic cycle. The Principal Components Analysis (PCA) discriminated the system based on the largest values registered for the limnological variables separating the periods influenced by droughts and rains. Most of the variables are associated with the rain period; however, sporadic concentration of nutrients in the drought and smaller dissolved oxygen values indicates a dilution difficulty in this period, caused by decrease of rain and consequently decrease of water volume in the streams.
