The aim of this research was to investigate the diversity patterns of benthic insects and functional feeding groups by assessing the contribution of α and β diversity components over 1 year. Temporal diversity variation as a function of the diversity components and regional rainfall in subterranean streams was also verified. Diversity components varied significantly at different spatial scales. In general, α diversity tended to be smaller and less varied temporally than the β diversity components. In addition, we detected a higher contribution of β 2 , indicating the importance of the regional species pool. Finally, for all significant models relating diversity values with rainfall, the relationship was negative. Intense flows leached organisms, leading to homogenization of communities. On the other hand, despite this negative effect, each functional feeding group responds differently to the hydrological stress, which makes it difficult to develop community predictability models after a disturbance.

地下溪流底栖昆虫的时间多样性模式：以巴西石英岩洞穴为例

本研究的目的是通过评估 α 和 β 多样性成分超过 1 年的贡献来研究底栖昆虫和功能性摄食群体的多样性模式。还验证了作为地下溪流中多样性成分和区域降雨量的函数的时间多样性变化。多样性成分在不同空间尺度上有显着差异。一般来说，α多样性往往比β多样性成分更小，时间上的变化也更小。此外，我们检测到 β 2 的贡献更高，表明区域物种库的重要性。最后，对于将多样性值与降雨量相关的所有重要模型，这种关系都是负相关的。强烈的水流浸出生物，导致群落的同质化。另一方面，尽管有这种负面影响，
