项目摘要

This proposal aims to study diversity dynamics and evolution patterns of bryozoans during the Carboniferous. Bryozoans are among the best-represented macroinvertebrates in the fossil record, because of the presence of a calcareous skeleton in the great majority of species. The Carboniferous bryozoan communities responded to the Late Devonian extinctions by renewed adaptive radiation and rediversification. Their diversity and evolution was influenced by such events as extensive glaciation and building of Pangaea. Bryozoan diversity could have been controlled by different extrinsic factors (climate, availability and quality of habitats, food supply) as well as intrinsic causes (environmental resistance/tolerance, adaptation, protecting, convergence, morphologic specialization etc.). The present study will include a critical species and genus level compilation of the data from the published literature and own taxonomic investigations. The compiled data base will be used to study diversity dynamics as well as rates of taxonomic turnover in bryozoans during the Carboniferous. The data gained will help to answer questions whether the bryozoan diversity during the Carboniferous was controlled by extrinsic or intrinsic factors, what kind of interaction between these factor groups could have existed, and how the bryozoan diversity and evolutionary patterns can be compared with those of other marine animal groups.

该提案旨在研究石炭纪期间苔藓族人的多样性动态和进化模式。由于绝大多数物种中存在钙质骨骼，因此bryozoans是化石记录中代表性最高的大型无脊椎动物之一。石炭纪的矮胖社区通过更新的适应性辐射和重新化来应对晚期的泥盆纪灭绝。他们的多样性和进化受到诸如广泛的冰川和pangea建设等事件的影响。 Bryozoan多样性本可以由不同的外部因素（气候，栖息地的可用性和质量，粮食供应）以及内在原因（环境抵抗/耐受性，适应性，保护，保护，收敛，形态专业化等）控制。本研究将包括关键物种和属水平汇编，来自已发表的文献和自己的分类学研究。汇编的数据库将用于研究石炭纪期间桥梁的多样性动态以及分类流动率。获得的数据将有助于回答问题的问题，是否由外部或内在因素控制了石炭纪期间的肌肉多样性，这些因素群之间可能存在什么样的相互作用，以及如何将其与其他与其他相比的肌肉多样性和进化模式相比海洋动物群体。
