The Interim Register of Marine and Nonmarine Genera is a provisional (or ‘interim’) compilation of genus names
– including species names in many cases – and covers both living and extinct biota into a single system to support
taxonomic and other queries dealing with e.g. homonyms, authorities, parent-child relationships, spelling variations
and distinctions between marine and non-marine or fossil and recent taxa.
Taxonomic names in IRMNG are assigned flags to distinguish between marine vs. non-marine, and extant vs. fossil status;
they are also arranged into a simple management hierarchy for navigation purposes, compilation of statistics per taxonomic group and more.
Fuzzy matching is also supported (using "Taxamatch") so that a misspelled name can in most instances be reconciled to a correctly spelled name
at genus or species rank, where this is held.
IRMNG commenced in 2006 following an analysis of needs in respect of taxonomic names management for the Ocean Biogeographic Information System (OBIS).
The main objectives were to fill the gaps and produce a hierarchical classification of all life, extant + fossil, to at least genus level
and provide a tool to distinguish marine from non-marine taxa.
It was designed as a contribution to the International OBIS system from OBIS Australia,
which is hosted at CSIRO Marine and Atmospheric Research (CMAR) in Australia, and also used as taxonomic information system by other initiatives.
CMAR contributed in kind to IRMNG development and ongoing hosting as part of its commitment to OBIS AU,
and small amounts of OBIS, GBIF and Atlas of Living Australia funds have contributed to aspects of its population.
Late 2013, the database manager and curator of IRMNG – Tony Rees, who was awarded the prestigious
GBIF Ebbe Nielsen Prize for 2014- started to look
for a new host institute for his database. The Flanders Marine Institute (VLIZ) made an offer –
including hosting, adding & distributing content and the possible development of new features for IRMNG – which has been accepted by
Tony and the former host institute CSIRO in Australia. During 2014 and 2015, the data transfer and integration from CSIRO to VLIZ was prepared,
leading to the new launch early 2016.
Sources & Contributors
Initial sources utilised for creation of IRMNG include the Nomenclator Zoologicus compilation of zoological genus names (1758-2004),
the Index Nominum Genericorum compilation of botanical names (sensu lato), the Catalogue of Life compilation of species names
(2006 version, to be updated in due course) and a range of others including both databases and print works.
Frequently the required information on a given name is required to be assembled from multiple sources,
for example Nomenclator Zoologicus gives names but not families or taxonomic status,
Index Nominum Genericorum gives names and families (which may have subsequently changed) but not taxonomic status, and so on.
Contributors to this project until 2014 include:
The project has also been assisted by two small grants from the Global Biodiversity Information Facility and support from the
Atlas of Living Australia.
The transfer of hosting institution for IRMNG will not cease the existing database nor stop the development and
updates of the register in the future. Close collaboration with Tony Rees will remain.
The Flanders Marine Institute (VLIZ) will provide ongoing hosting of the IRMNG data content,
using the same infrastructure that is currently provided to host the World Register of Marine Species (WoRMS)
and with the technical support already in place.
VLIZ will also support the web interfaces for the external users
so they can easily query existing and future IRMNG content and continue the delivery of IRMNG data dumps for the benefit of significant-scale
IRMNG users such as e.g. GBIF, EoL, ALA, OBIS and many more. In time – and as resources permit – VLIZ will develop additional services over both
IRMNG and WoRMS to serve the users’ needs. Also content-wise, VLIZ will contribute to IRMNG by committing to help build an editor network
– similar to the WoRMS editor network - who can help to keep the IRMNG information up-to-date and to help fill in the already identified gaps
within the database.
The transfer and hosting of IRMNG is supported by LifeWatch Belgium, part of the E-Science European LifeWatch Infrastructure for Biodiversity and Ecosystem Research.
LifeWatch is a distributed virtual laboratory which is used for different aspects of biodiversity research. The Taxonomic Backbone of LifeWatch aims at bringing
together taxonomic and species-related data and at filling the gaps in our knowledge.
