分类学的主要目标之一是提供关于一组生物多样性的综合知识，例如开花植物。生物多样性的保护和管理要求在物种一级进行快速和准确的全球评估。与此同时，进化生物学的快速发展，以及一系列测试物种关系和物种极限的方法，已经并仍在革命性地改变包括分类学在内的植物系统学科学。我们探讨了相关的科学和技术发展，目的是为能够覆盖全球的综合专题综合提出一个概念框架。我们的样本群是石竹目，这是一个分布在世界各地的谱系，大约包括。5%的开花植物物种多样性。目前的分类情况的特点是从系统发育前的处理方法向分类处理方法的过渡，越来越多地在进化的背景下进行评估。将结构化数据(包括分子和形态数据)链接到文件齐全的标本，作为可接受进化分析的基本信息实体将是重要的。因此，分类单元概念被建立为假设，然后可以在第二步中用作分类系统的基础。全球综合需要提供信息，并使用反映当前知识状态的分类系统。为了适应不断提高的对生物体的了解，最终也导致分类概念的改变，处理需要是动态的。这里概述的全球专题综合的工作流程得到了目前可用的生物多样性信息学工具的支持，例如网络分类学编辑平台。电子资源(姓名、原著、文字图片、文献)的可获得性极大地便利了信息的获取，但正如我们的案例所显示的那样，仍然需要在数据管理和研究方面作出相当大的努力。实施全球专题综合，如石竹目，需要全球科学界的参与。(C)2015年提交人。由Elsevier GmbH出版。代表地球植物研究所，Stiftung Ruebel。
One of the major goals of systematics is to provide a synthesis of knowledge on the diversity of a group of organisms, such as flowering plants. Biodiversity conservation and management call for rapid and accurate global assessments at the species level. At the same time the rapid development of evolutionary biology with a spectrum of approaches to test species relationships and species limits, has revolutionised and is still revolutionizing the science of plant systematics including taxonomy. We explore the relevant scientific and technological developments with the aim to suggest a conceptual framework for an integrated monographic synthesis which can reach global coverage. Our exemplar group are the Caryophyllales, which are a lineage of worldwide distribution, comprising approx. 5% of flowering plant species diversity. The current situation of classification is marked by a transition from pre-phylogenetic treatments to taxonomic treatments increasingly evaluated in an evolutionary context. Structured data (both molecular and morphological), linked to well-documented specimens will be important as fundamental entities of information that can be subjected to evolutionary analysis. As a result, taxon concepts are established as hypotheses which then can be used as basis for a classification system in a second step. Global syntheses need to provide information and use a classification system that reflects the current state of knowledge. In order to accommodate the constantly improved understanding of the organisms, eventually also resulting in the change of taxon concepts, the treatments need to be dynamic. The work-flow for a global monographic synthesis as outlined here is supported by currently available biodiversity informatics tools such as the EDIT Platform for Cybertaxonomy. The availability of electronic sources (names, protologues, type images, literature) greatly facilitates the access to information, but as our case shows, considerable efforts for data curation and research are still needed. The implementation of a global monographic synthesis such as the Caryophyllales requires the involvement of the global scientific community. (C) 2015 The Authors.
