项目摘要

This project is a contribution to the development of workflows for the acceleration of biodiversity inventorying and for species re-identification in complex ecosystems, as described in the introductory text for the “ABA Ecuador” group. We will focus on a species-rich group of herbivorous beetles, the Chrysomelidae, and combine for this purpose the expertise of two different working groups, one for the taxonomy and biology of these beetles (second applicant), and one for molecular biodiversity research (first applicant). More than 40.000 species of Chrysomelidae have been described to date globally. Their relationship with food plants is little studied. A detailed analysis of host-specificity and of species ranges along altitudinal gradients is necessary to understand mechanisms that maintain high biodiversity in tropical mountain forests. Since taxonomic work requires much time and many experts, our approach will be “reverse taxonomy”: starting with the development of species-specific markers, vouchering of specimens, linking metadata, sequence data and images for each voucher in databases, to enable later classical taxonomic work with the same material. The results will be used to test a series of ecological hypotheses concerning the correlation of community composition and species presence with the diversity of other organisms and with environmental parameters.

正如“ABA 厄瓜多尔”小组的介绍性文本所述，该项目有助于开发工作流程，以加速生物多样性清查和复杂生态系统中的物种重新识别。我们将重点关注物种丰富的群体。食草甲虫，叶甲科，并为此目的结合了两个不同工作组的专业知识，一个负责这些甲虫的分类学和生物学（第二申请人），另一个负责分子生物多样性研究（第一申请人）。迄今为止，全球已描述了超过 40,000 种叶甲科物种，但对它们与食用植物的关系的研究很少，需要对宿主特异性和沿海拔梯度的物种范围进行详细分析，以了解维持热带山地森林高生物多样性的机制。由于分类工作需要大量时间和许多专家，我们的方法将是“反向分类”：从开发物种特异性标记、标本凭证、链接元数据、序列数据和图像开始数据库中的每个凭证，以便以后使用相同材料进行经典分类学工作。结果将用于测试一系列有关群落组成和物种存在与其他生物多样性和环境参数之间的相关性的生态假设。
