Because the correct use of names and names relationships is essential for biodiversity management, the availability of taxonomically validated standardised nomenclatures is fundamental for biological e-infrastructures. PESI is the next step in integrating and securing taxonomically authoritative species name registers that underpin the management of biodiversity in Europe. PESI will integrate the three main all-taxon registers in Europe, namely the European Register of Marine Species, Fauna Europaea, and Euro+Med PlantBase in coordination with EU-based nomenclators, i.e. Index Fungorum, IPNI, and AlgaeBase, plus the network of EU-based Global Species Databases (GSDs). It is a standards-based, quality controlled, expert validated, open-access infrastructure for research, education, and resource management.
PESI is a joint initiative of two Networks of Excellence: EDIT (European Distributed Institute of Taxonomy) and MarBEF (Marine Biodiversity and Ecosystem Functioning), funded by the European Union under the Framework 7 Capacities Work Programme: Research Infrastructures
