LIAS

LIAS is a global information system for Lichenized and Non-Lichenized Ascomycetes. It includes several interoperable data repositories. In recent years, the two core components ‘LIAS names’ and ‘LIAS light’ have been much enlarged. LIAS light is storing phenotypic trait data. They includes 10,700 descriptions (about 2/3 of all known lichen species), each with up to 75 descriptors comprising 2,000 traits (descriptor states and values), including 800 secondary metabolites. 500 traits may have biological functions and more than 1,000 may have phylogenetic relevance. LIAS is thus one of the most comprehensive trait databases in organismal biology. The online interactive identification key for more than 10,700 lichens is powered by the Java applet NaviKey and has been translated into 19 languages (besides English) in cooperation with lichenologists worldwide. The component ‘LIAS names’ is a platform for managing taxonomic names and classifications with currently 50,000 names, including the c. 12,000 accepted species and recognized synonyms. The LIAS portal contents, interfaces, and databases run on servers of the IT Center of the Bavarian Natural History Collections and are maintained there. 'LIAS names' and ‘LIAS light’ also deliver content data to the Catalogue of Life, acting as the Global Species Database (GSD) for lichens. LIAS gtm is a database for visualising the geographic distribution of lichen traits. LIAS is powered by the Diversity Workbench database framework with several interfaces for data management and publication. The LIAS long-term project was initiated in the early 1990s and has since been continued with funding from the DFG, the BMBF, and the EU.

LIAS（地衣化与非地衣化子囊菌全球信息系统）是一个包含多个互操作数据存储库的信息系统。近年来，其两大核心组件‘LIAS名称’和‘LIAS轻量级’得到了显著扩充。‘LIAS轻量级’用于存储表型性状数据，包含10,700条描述（约占已知地衣物种的2/3），每条描述包含多达75个描述符，涉及2,000个性状（描述符状态和值），其中包括800种次级代谢物。约500个性状具有生物学功能，超过1,000个可能与系统发育相关。因此，LIAS成为有机生物学中最全面的性状数据库之一。超过10,700种地衣的在线交互式鉴定键由Java小程序NaviKey提供支持，并与全球地衣学家合作翻译成19种语言（除英语外）。‘LIAS名称’组件是一个管理分类名称和分类的平台，目前包含50,000个名称，包括约12,000个被接受物种和已认可的同义词。LIAS门户的内容、界面和数据库运行在巴伐利亚自然历史收藏信息技术中心的服务器上，并由其维护。‘LIAS名称’和‘LIAS轻量级’还向《生命目录》提供内容数据，作为地衣的全球物种数据库（GSD）。LIAS gtm是一个用于可视化地衣性状地理分布的数据库。LIAS由Diversity Workbench数据库框架提供支持，具有多个数据管理和发布接口。LIAS长期项目始于20世纪90年代初，并自那时起由DFG、BMBF和欧盟的资金支持持续进行。
