| Título: | Stonefly (Plecoptera) fauna of streams in a mountainous area of central Brazil: abiotic factors and nymph density |
| Autor: | Bispo, Pitágoras da Conceição Froehlich, Cláudio Gilberto Oliveira, Leandro Gonçalves |
| Resumo: | The stonefly (Plecoptera) nymphs of streams of the Almas River basin, Pirenópolis, Goiás State, Central Brazil, and some abiotic factors that might affecttheir temporal distribution were studied. Nymphs were sampled monthly (June 1993to July 1994) in five stations with a Surber sampler, and each sample consisted of 20 unils totalling 2 m2 ln each station, stream velocity, discharge, temperature, electrical conductivity and pH were measured in order to assess their influence on the density of nymphs. Nymphs were identified to genus leveI. ln general, lhe annual variation in density of nymphs, in four slations, showed lhal lhe seasonal variation was not clearly influenced by the annual rain cycle. ln the case ofthe one oflhe slalions, where numbers of stonefly nymphs were low and the anlhropic action high, there was a density peak in lhe rainy season. This peak was probably related to dilution of lhe organic pollution in lhe rainy season, improving lhe environmental condilions for lhe Plecoptera. |
