摘要: |
满月蛤目物种是海洋常见的双壳类软体动物,通常生活在有机质含量较高或化能生态系统中,是这两类生态环境中的主要类群。本文回顾了满月蛤目分类与系统演化的研究历史。随着受关注程度的增加以及技术手段的发展,世界范围内出现大量的分类和系统演化研究,但由于物种繁多、样品获取困难、贝壳形态多变,该类群的分类系统仍存在大量尚未解决的问题,且其物种多样性被严重低估。我国对该类群系统性的研究尚未开展。未来需加强标本采集,结合新技术进行整合分类学研究以摸清我国满月蛤目物种组成和区系特点,完善分类系统,进而对其起源演化、扩布路径等问题进行探究。 |

Abstract: |
Marine bivalves of the order Lucinida that live primarily in habitats with high organic input or chemosynthesis have attracted interest by the discovery of their chemosymbiosis with sulfide-oxidizing bacteria. The unsolved problems in the taxonomy of Lucinida entangle its systematics. The phylogenetic relationship between the families Lucinidae and Thyasiridae within Lucinida remains controversial. Moreover, many taxa have not been well delimited. Continuing systematic studies of this group have demonstrated that their biodiversity has been grossly underestimated, with a plethora of new species and genera being described from shallow- and deep-water habitats in the past two decades. This group has not been thoroughly studied in the Chinese seas, which is a marine biodiversity center. The species richness of this group has never been adequately documented, with many unknown species yet to be discovered. Taxonomic studies in China have lagged behind the international level. A detailed sampling survey and systematic studies using an integrative taxonomic approach are needed for Lucinida in Chinese waters. |
