Beta-diversity measures have been used to understand patterns of community distribution in natural ecosystems. Recent studies included different facets of beta-diversity analyses, e.g. trait- and phylogeny-based. Here, we used ostracod communities to evaluate the influence of environmental and spatial factors structuring different facets of beta-diversity and their components (Beta-total, replacement and richness-difference) of ostracod communities associated with different macrophyte life forms. We test the hypotheses (1) that the influence of environmental factors is higher for ostracod beta-diversity facets of communities associated with submerged plants compared to emergent and floating plants and (2) that the influence of spatial factors is higher in communities associated with rooted, compared to non-rooted plants. Ostracods were sampled from five life forms of macrophytes, including emergent, rooted floating, rooted submerged, free submerged and free floating in 25 floodplain lakes. Our results showed that the environmental factors turned out to be important for all beta-diversity facets of ostracod communities, mainly for those associated with submerged macrophytes, thus corroborating the first hypothesis. We also found that spatial factors’ influence on ostracod beta-diversity was not related to whether the plant is rooted or not, thus refuting our second hypothesis. We also found differences in factors structuring each of the beta-diversity facets, showing the importance to include these three approaches (species-, traits- and phylogeny-based) in ecological surveys. Finally, we highlight the importance of considering different macrophyte life forms in biodiversity surveys for the preservation and management of the diversity of these plants and their associated communities.

Beta多样性度量已用于了解自然生态系统中社区分布的模式。最近的研究包括β多样性分析的不同方面，例如基于性状和系统发育的分析。在这里，我们使用了兽类群落来评估环境和空间因素的影响，这些环境和空间因素构成了与不同大型植物生命形式相关的兽类群落的β多样性多样性及其组成部分（总数，置换和富集-差异）的β面。我们检验了以下假设：（1）与淹没植物和浮游植物相比，与淹没植物相关联的群落的成虫β-多样性方面环境因素的影响更高；（2）与生根相关联的群落中，空间因素的影响较高，与无根植物相比。从25种洪泛区湖泊中的五个生命形式的大型植物中提取了兽脚类生物，包括生出的，有根的漂浮物，有根的淹没物，游离的淹没物和游离的漂浮物。我们的研究结果表明，环境因素对于整个类群的β-多样性方面都很重要，主要是对于那些与淹没的大型植物相关的方面，因此证实了第一个假设。我们还发现，空间因素对成虫类β-多样性的影响与植物是否生根无关，因此驳斥了我们的第二个假设。我们还发现构成每个β多样性方面的因素存在差异，表明在生态调查中包括这三种方法（基于物种，基于特征和基于系统发育的方法）的重要性。最后，
