Abstract：
The introduction of invasive species has become an increasing environmental problem in freshwater ecosystems due to the high economic and ecological impacts it has generated. This systematic review covers publications from 2010 to 2020, focusing on non-native invasive freshwater bivalves, a particularly relevant and widespread introduced taxonomic group in fresh waters. We collected information on the most studied species, the main objectives of the studies, their geographical location, study duration, and type of research. Furthermore, we focused on assessing the levels of ecological evidence presented, the type of interactions of non-native bivalves with other organisms and the classification of their impacts. A total of 397 publications were retrieved. The studies addressed a total of 17 species of non-native freshwater bivalves; however, most publications focused on the species Corbicula fluminea and Dreissena polymorpha, which are recognised for their widespread distribution and extensive negative impacts. Many other non-native invasive bivalve species have been poorly studied. A high geographical bias was also present, with a considerable lack of studies in developing countries. The most frequent studies had shorter temporal periods, smaller spatial extents, and more observational data, were field-based, and usually evaluated possible ecological impacts at the individual and population levels. There were 94 publications documenting discernible impacts according to the Environmental Impact Classification for Alien Taxa (EICAT). However, 41 of these publications did not provide sufficient data to determine an impact. The most common effects of invasive bivalves on ecosystems were structural alterations, and chemical and physical changes, which are anticipated due to their role as ecosystem engineers. Despite a considerable number of studies in the field and advances in our understanding of some species over the past decade, long-term data and large-scale studies are still needed to understand better the impacts, particularly at the community and ecosystem levels and in less-studied geographic regions. The widespread distribution of several non-native freshwater bivalves, their ongoing introductions, and high ecological and economic impacts demand continued research. Systematic reviews such as this are essential for identifying knowledge gaps and guiding future research to enable a more complete understanding of the ecological implications of invasive bivalves, and the development of effective management strategies.
摘要：
由于其产生的高度经济和生态影响，入侵物种的引入已成为淡水生态系统中日益严重的环境问题。本系统综述涵盖2010年至2020年的出版物，重点是非本地侵入性淡水双壳类动物，淡水中一个特别相关和广泛引入的分类群。我们收集了研究最多的物种的信息，研究的主要目标，他们的地理位置,研究持续时间，和研究类型。此外，我们专注于评估所提供的生态证据的水平，非天然双壳类与其他生物相互作用的类型及其影响的分类。共检索到397份出版物。这些研究涉及总共17种非本地淡水双壳类动物；然而，大多数出版物都集中在种Corbiculafluminia和Dreissenapolymorpha上，因其广泛分布和广泛的负面影响而得到认可。许多其他非天然侵入性双壳类动物物种的研究很少。还存在高度的地理偏见，在发展中国家相当缺乏研究。最常见的研究时间较短，较小的空间范围，和更多的观测数据，是基于现场的，并通常在个人和人口层面评估可能的生态影响。根据《外来分类群环境影响分类》（EICAT），有94份出版物记录了可辨别的影响。然而,这些出版物中有41篇没有提供足够的数据来确定影响。侵入性双壳类动物对生态系统最常见的影响是结构改变，以及化学和物理变化，由于他们作为生态系统工程师的角色而被预期。尽管在过去十年中，在该领域进行了大量研究，并且我们对某些物种的理解有所进步，仍然需要长期数据和大规模研究来更好地了解影响，特别是在社区和生态系统层面以及研究较少的地理区域。几种非本地淡水双壳类动物的广泛分布，他们正在进行的介绍，和高生态和经济影响需要继续研究。像这样的系统评价对于识别知识差距和指导未来的研究是必不可少的，以便更全面地了解侵入性双壳类动物的生态影响。并制定有效的管理策略。
