Changes in land cover are the main threats to integrity and biodiversity of wetlands. Here, we evaluated the effects of agriculture and urbanization on the functional traits (FT) of aquatic invertebrate. We evaluated 30 wetlands distributed among agricultural, urban and natural landscapes on the south of Brazil. We selected eight FT that encompassed aspects of life history, morphology and behavioral strategies to functionally characterize invertebrate fauna and 10 environmental variables of wetlands. We collected 3868 organisms distributed among 138 taxa (Crustacea, Mollusca, Hexapoda. The RLQ analysis (environmental, R; species-abundances, L; species-traits, Q) showed that there was a relationship between environmental conditions and the functional composition of the invertebrates. The FT that were more sensitive to environmental changes were scrapers feeding habit, reproduction mode, resistance form, adult aquatic stage, flat body shape, and dispersal mode. Our results suggest that land use acted as environmental filters, as they promote the selection and convergence of specific characteristics that give organisms more resilience and/or resistance to cope with the effects of anthropogenic disturbances. Also this results showed that (i) human disturbance can influence directly on the dynamic of the wetlands ecosystems functioning and (ii) the efficiency of the use FT in the environmental monitoring.

土地覆盖的变化是对湿地完整性和生物多样性的主要威胁。在这里，我们评估了农业和城市化对水生无脊椎动物功能特征（FT）的影响。我们评估了巴西南部农业，城市和自然景观中分布的30个湿地。我们选择了八个FT，涵盖了生活史，形态和行为策略的各个方面，以在功能上表征无脊椎动物和湿地的10个环境变量。我们收集了分布在138个类群（甲壳纲，软体动物，六足纲）中的3868种生物。RLQ分析（环境，R；物种丰度，L；物种特征，Q）表明，环境条件与该物种的功能组成之间存在关系。无脊椎动物。对环境变化更敏感的FT是刮刀的进食习惯，繁殖方式，抵抗形式，成年水生阶段，扁平体形和扩散方式。我们的研究结果表明，土地利用起到了环境过滤器的作用，因为它们促进了特定特征的选择和融合，从而赋予生物更多的适应力和/或抵抗力，以应对人为干扰的影响。该结果还表明，（i）人为干扰可以直接影响湿地生态系统功能的动态，并且（ii）在环境监测中使用FT的效率。因为它们可以促进特定特征的选择和融合，从而赋予生物更多的适应力和/或抵抗力，以应对人为干扰的影响。该结果还表明，（i）人为干扰可以直接影响湿地生态系统功能的动态，并且（ii）在环境监测中使用FT的效率。因为它们可以促进特定特征的选择和融合，从而赋予生物更多的适应力和/或抵抗力，以应对人为干扰的影响。该结果还表明，（i）人为干扰可以直接影响湿地生态系统功能的动态，并且（ii）在环境监测中使用FT的效率。
