We conducted a systematic review to investigate the relationship between aquatic insects and climatic seasonality in the Cerrado biome in Brazil. The review encompassed the number of studies, the spatial distribution of studies across microbasins, the duration of the studies, collection methods, taxonomic resolutions, the most significant environmental predictors for the communities, and the impact of land-use changes on the seasonal variation of aquatic insect communities. We also tested the relationship between climatic seasonality and aquatic insect diversity using a meta-analysis and discussed the potential effects of climate change on these communities. To achieve this, we used a set of keywords related to aquatic insects and climatic seasonality in the Cerrado biome to search Scopus and Web of Science databases. Our main findings indicate that the collection methods are robust and well-established, and taxonomic resolutions are generally good. However, the number of streams and the duration of sampling are often inadequate for addressing ecological questions in most studies. Additionally, the spatial distribution of studies is concentrated around areas close to universities. Finally, it was evident that the richness and abundance of aquatic insects are higher during the dry season. These results indicate ways to improve studies with temporal questions using aquatic insect communities in the Cerrado and raise awareness about the potential issues caused by climate change. Changes in precipitation patterns and temperature are expected to transform some of the currently perennial streams into intermittent ones, thereby homogenizing aquatic insect communities and negatively impacting their potential to provide ecosystem services.
我们进行了一项系统综述，以研究巴西塞拉多生物群落中水生昆虫与气候季节性之间的关系。该综述涵盖了研究数量、跨微流域研究的空间分布、研究持续时间、收集方法、分类分辨率、群落最重要的环境预测因子，以及土地利用变化对水生昆虫群落季节变化的影响。我们还使用荟萃分析检验了气候季节性与水生昆虫多样性之间的关系，并讨论了气候变化对这些群落的潜在影响。为此，我们使用了一组与塞拉多生物群落中的水生昆虫和气候季节性相关的关键词，在Scopus和Web of Science数据库中进行检索。我们的主要研究结果表明，收集方法可靠且成熟，分类分辨率总体良好。然而，在大多数研究中，溪流数量和采样持续时间往往不足以解决生态学问题。此外，研究的空间分布集中在靠近大学的区域。最后，很明显，水生昆虫的丰富度和丰度在旱季更高。这些结果表明了改进利用塞拉多水生昆虫群落进行时间问题研究的方法，并提高了对气候变化可能引发的潜在问题的认识。预计降水模式和温度的变化将使一些目前常年性的溪流转变为间歇性溪流，从而使水生昆虫群落同质化，并对其提供生态系统服务的潜力产生负面影响。
