The development of biomonitoring programs based on the macroinvertebrate community requires the understanding of species distribution patterns, as well as of the responses of the community to anthropogenic stressors. In this study, 49 metrics were tested as potential means of assessing the condition of 29 first- and second-order streams located in areas of differing types of land use in São Paulo State, Brazil. Of the sampled streams, 15 were in well-preserved regions in the Atlantic Forest, 5 were among sugarcane cultivations, 5 were in areas of pasture, and 4 were among eucalyptus plantations. The metrics were assessed against the following criteria: (1) predictable response to the impact of human activity; (2) highest taxonomic resolution, and (3) operational and theoretical simplicity. We found that 18 metrics were correlated with the environmental and spatial predictors used, and seven of these satisfied the selection criteria and are thus candidates for inclusion in a multimetric system to assess low-order streams in São Paulo State. These metrics are family richness; Ephemeroptera, Plecoptera and Trichoptera (EPT) richness; proportion of Megaloptera and Hirudinea; proportion of EPT; Shannon diversity index for genus; and adapted Biological Monitoring Work Party biotic index.
基于大型无脊椎动物群落的生物监测计划的发展需要了解物种分布模式，以及群落对人为胁迫的响应。在这项研究中，测试了 49 项指标，作为评估巴西圣保罗州不同土地利用类型地区的 29 条一级和二级溪流状况的潜在手段。在所采样的溪流中，有 15 条位于大西洋森林的保护区内，5 条位于甘蔗种植区，5 条位于牧场区，4 条位于桉树种植区。这些指标是根据以下标准进行评估的：(1) 对人类活动影响的可预测响应；(2) 最高的分类分辨率；(3) 操作和理论的简单性。我们发现，有 18 项指标与所使用的环境和空间预测因子相关，其中有 7 项指标符合选择标准，因此是纳入评估圣保罗州低阶溪流的多指标系统的候选指标。这些指标是科的丰富度；蜉蝣目、石蝇目和毛翅目（EPT）的丰富度；广翅目和蛭纲的比例；EPT 的比例；属的 Shannon 多样性指数；以及适应性生物监测工作小组生物指数。
