Resumo: Abundance-occupancy relationships of Trichoptera larvae, estimated in two seasons, were compared to evaluate the following hypothesis: hydrologic instability during the rain season is the main mechanism which reduces the magnitude of these relationships in streams located in the Cerrado region, Centre-West of Brazil. The larvae density was determined from 18 sampling stations in a region surrounding the Parque Estadual da Serra de Caldas, Caldas Novas, Estado de Goiás, by Surber sampler. The distribution of each taxon was given by the number of occurrences in the region. During the dry season (July), a significant correlation between abundance-occupancy was detected (r =0.606; n = 20; P < 0.005). On the other hand, such relationships were not significant during rainy periods. These results support the hypothesis that, during the periods of hydrological stability, abundance and distribution patterns of Trichoptera were controlled by the interaction of organisms tolerance and environment gradients. Besides, the relative importance of stochastic and deterministic, acting on benthonic insects may be temporally dependent

As densidades das larvas foram estimadas a partir de coletas quantitativas em 18 pontos amostrais no entorno do Parque Estadual da Serra de Caldas (Caldas Novas, Estado de Goiás), obtidas pelo amostrador de Surber. A distribuição dos táxons foi dada pelo número de ocorrências na região. As análises realizadas demonstraram que, no ápice do período de seca, houve uma correlação de Pearson significativa entre a distribuição e a abundância das larvas (julho: r = 0,606, n= 20, P < 0,005). Por outro lado, nas coletas realizadas sob a influência de precipitações pluviométricas, os valores não foram significativos. Esses resultados apóiam a hipótese de que, durante os períodos de estabilidade hidrológica, os padrões de distribuição espacial e a abundância resultaram da interação entre os gradientes ambientais e as tolerâncias dos organismos. Além disso, demonstraram que a importância relativa de processos estocásticos e determinísticos, atuando sobre as comunidades desses insetos bentônicos, pode variar temporalmenteUniversidade Estadual De Maringá2008-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/136010.4025/actascibiolsci.v27i1.1360Acta Scientiarum.
