摘要

本研究首次对喀拉拉邦阿什塔穆迪湖沉积物中出现的梭形纲动物进行了分类，旨在为未来的古生态学或古环境应用提供一个基准。从湖中采集的 66 个表层沉积物样本中，共鉴定出隶属于 Podocopida 目 16 属、11 科、5 超科和 2 亚目的 22 个 Ostracod 种类。对 CaCO3、有机质、砂质粉土和粘土等沉积物参数进行了估算，并讨论了它们的分布情况。在确定研究区域的沉积速率时，考虑了瓣膜与开放瓣膜之间的比率。

A first report on the distribution of Ostracod taxa in the Ashtamudi Lake, southwest coast of Kerala, India

The present study is the first taxonomical account of Ostracoda occurring in the sediments of the Ashtamudi Lake in Kerala, intending to generate a baseline for future palaeo-ecological or palaeoenvironmental applications. A total of 22 Ostracod species belonging to 16 genera, 11 families, 5 superfamilies and 2 suborders of the order Podocopida have been identified from 66 surface sediment samples collected across the lake. Sedimentological parameters, such as CaCO3, organic matter, sand silt and clay, were estimated and their distribution is discussed. The ratio between the carapaces and open valves has been taken into consideration for determining the rate of sedimentation in the study area.
