Census of marine zooplankton in Southeast Asia

本研究以受人类活动和气候变化威胁的生物多样性热点地区东南亚沿海生态系统为研究对象，旨在扩大我们对浮游动物的定量认识。在对现有资料进行分类、分子遗传学和生态学分析的基础上，我们发现并描述了迄今为止未知的大约20种桡足类，并证明了在几个已知物种中存在遗传分化的隐种。我们还通过对现有样本/论文的分析/挖掘，将大约16000个数据点的浮游动物分布定量数据数字化。在毛齿纲方面，我们编制了印度-太平洋地区物种多样性的分布格局，并建立了基于环境参数的物种多样性（物种丰富度和多样性）预测模型。

Focusing on the coastal ecosystems in Southeast Asia, which is a biodiversity hotspot under the threats of human activities and climate change, this study aimed at expanding our quantitative knowledge on zooplankton. On the basis of taxonomic, molecular-genetic, and ecological analyses of existing materials, we discovered and described ca. 20 species of copepods so far unknown, and demonstrated presence of genetically-differentiated cryptic species within several known species. We also digitized quantitative data of zooplankton distribution from ca. 16,000 data points by analyses/mining of existing samples/papers. As for chaetognaths, we compiled the distributional patterns of species diversity in the Indo-Pacific Region, and established/published a model to predict species diversity (species richness and diversity) from environmental parameters.
