Gloeosporium lupini Bondar is transferred to Colletotrichum. The fungus is characterized morphologically and illustrated. The two varieties, Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagedorn, comb. nov. var. lupini and Colletotrichum lupini var. setosum Nirenberg, Feiler & Hagedorn var. nov. are described. They are compared with additional(More)
Fauna Europaea is Europe's main zoological taxonomic index, making the scientific names and distributions of all living, currently known, multicellular, European land and freshwater animals species integrally available in one authoritative database. Fauna Europaea covers about 260,000 taxon names, including 145,000 accepted (sub)species, assembled by a(More)
The article describes an extended entity-relationship model covering biological collections, i.e. natural history collections of biotic origin; data collections used in floristic or faunistic mapping, survey, and monitoring projects; live collections such as botanical or zoological gardens, seed banks, microbial strain collections and gene banks; as well as(More)
As biological disciplines extend into the ‘big data’ world, they will need a names-based infrastructure to index and interconnect distributed data. The infrastructure must have access to all names of all organisms if it is to manage all information. Those who compile lists of species hold different views as to the intellectual property rights that apply to(More)
Background. The 7(th) Framework Programme for Research and Technological Development is helping the European Union to prepare for an integrative system for intelligent management of biodiversity knowledge. The infrastructure that is envisaged and that will be further developed within the Programme "Horizon 2020" aims to provide open and free access to(More)
Relationships among East Asian, North American and European Laetiporus sulphureus s. lat., a cosmopolitan brown rot species complex, were assessed with phylogenetic analyses and incompatibility tests. Three East Asian taxa, Laetiporus cremeiporus sp. nov., Laetiporus montanus and Laetiporus versisporus, are described and illustrated as well as compared with(More)
The success of the collaborative web-based MediaWiki platform, widely used in several projects to exchange knowledge created a new idea to use this system as a low-tech interoperability and repository layer for data providers, end users, developers and project partners. Facilitating the acquisition of knowledge for multimedia digital resources is a task(More)
With biodiversity research activities being increasingly shifted to the web, the need for a system of persistent and stable identifiers for physical collection objects becomes increasingly pressing. The Consortium of European Taxonomic Facilities agreed on a common system of HTTP-URI-based stable identifiers which is now rolled out to its member(More)
A list of all generic names that have been connected with the Orbiliomycetes is provided. Recommendations are made as to which names should be used in accordance with the rules and the different generic concepts. There is a mismatch in the current generic concepts within Orbiliomycetes regarding the two morphs: a narrow concept is used for the asexual(More)
Biodiversity data is being digitized and made available online at a rapidly increasing rate but current practices typically do not preserve linkages between these data, which impedes interoperation, provenance tracking, and assembly of larger datasets. For data associated with biocollections, the biodiversity community has long recognized that an essential(More)
