The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database which attempts to cover published genus names for all domains of life from 1753 in zoology (1758 in botany) up to approximately 2014, arranged in a single, internally consistent taxonomic hierarchy, for the benefit Biodiversity Informatics initiatives plus general users of biodiversity (taxonomic) information. In addition to containing over 490,000 published genus name instances as at March 2020 (also including subgeneric names in zoology), the database holds over 1.7 million species names (1.3 million listed as "accepted"), although this component of the data is not maintained in as current or complete state as the genus-level holdings. IRMNG can be queried online for access to the latest version of the dataset and is also made available as periodic snapshots or data dumps for import/upload into other systems as desired.



IRMNG contains scientific names (only) of the genus, species, and higher ranks of many plants, animals and other kingdoms, both living and extinct, within a standardized taxonomic hierarchy, with associated machine-readable information on habitat (e.g. marine/nonmarine) and extant/fossil status for the majority of entries. [1] The database aspires to provide complete coverage of both accepted and unaccepted genus names across all kingdoms, with a subset only of species names included as a lower priority. In its March 2020 release, IRMNG contained 492,620 genus names, of which 232,093 were listed as "accepted", 121,389 "unaccepted", 7,462 of "other" status i.e. interim unpublished, nomen dubium, nomen nudum, taxon inquirendum or temporary name, and 131,676 as "uncertain" (unassessed for taxonomic status at this time). [2] The data originate from a range of (frequently domain-specific) print, online and database sources, including (among others) Nomenclator Zoologicus for animals and Index Nominum Genericorum for plants, and are reorganised into a common data structure to support a variety of online queries, generation of individual taxon pages, and bulk data supply to other biodiversity informatics projects. IRMNG content can be queried and displayed freely via the web, and download files of the data down to the taxonomic rank of genus as at specific dates are available in the Darwin Core Archive (DwC-A) format. The data include homonyms (with their authorities), including both available (validly published) and selected unavailable names. [3]

Database location and hosting

IRMNG was initiated and designed by Tony Rees in 2006. [1] [4] For his work on this and other projects, GBIF awarded him the 2014 Ebbe Nielsen Prize. [4] From 2006-2014 IRMNG was located at CSIRO Marine and Atmospheric Research, and was moved to the Flanders Marine Institute (VLIZ) over the period 2014–2016; from 2016 onwards all releases have been available via its new website which is hosted by VLIZ. [1] [5] VLIZ also hosts the World Register of Marine Species (WoRMS), using a common infrastructure. [6]

IRMNG usage

Content from IRMNG is used by several global Biodiversity Informatics projects including Open Tree of Life, [7] the Global Biodiversity Information Facility (GBIF), [8] and the Encyclopedia of Life (EOL), [9] in addition to others including the Atlas of Living Australia [10] and the Global Names Architecture (GNA)'s Global Names Resolver. [11] From 2018 onwards, IRMNG data are also being used to populate the taxonomic hierarchy and provide generic names for a range of taxa in the areas of protists (kingdoms Protozoa and Chromista) and plant algae (Charophyta, Chlorophyta, Glaucophyta and Rhodophyta) in the Catalogue of Life. [12] IRMNG identifiers have also been associated with numerous Wikipedia taxon pages, based on content harvested from IRMNG and stored in Wikidata. [13]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Ebbe Schmidt Nielsen was a Danish entomologist. Nielsen was influential in systematics and Lepidoptera research, and was an early proponent of biodiversity informatics. The journal Invertebrate Systematics was established with significant contributions from Nielsen and he assisted in the founding of the Global Biodiversity Information Facility (GBIF). Nielsen authored several books, published over eighty scientific papers, and was highly regarded within the scientific community. Following his death, the GBIF organised the Ebbe Nielsen Prize in his memory, awarded annually to promising researchers in the field of biodiversity informatics. The moth Pollanisus nielseni is dedicated to Nielsen.

<i>Scinax</i> genus of amphibians

Scinax is a genus of frogs in the family Hylidae found in eastern and southern Mexico to Argentina and Uruguay, Trinidad and Tobago, and Saint Lucia. These are small to moderate-sized tree frogs, drably colored. Duellman and Wiens resurrected this genus in 1992. The name originates from the Greek word skinos, meaning quick or nimble.

Global Biodiversity Information Facility Aggregator of scientific data on biodiversity; data portal

The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data.

<i>Ansonia</i> (genus) genus of amphibians

Ansonia is a genus of true toads found in south India, northern Thailand, Malay Peninsula, Tioman Island, Borneo, and Mindanao (Philippines). These small forest species spawn in streams and have torrent-adapted tadpoles. Common name stream toads has been coined for the genus, although individual species are also being referred to as slender toads.

Biodiversity Informatics is the application of informatics techniques to biodiversity information for improved management, presentation, discovery, exploration and analysis. It typically builds on a foundation of taxonomic, biogeographic, or ecological information stored in digital form, which, with the application of modern computer techniques, can yield new ways to view and analyse existing information, as well as predictive models for information that does not yet exist. Biodiversity informatics is a relatively young discipline but has hundreds of practitioners worldwide, including the numerous individuals involved with the design and construction of taxonomic databases. The term "Biodiversity Informatics" is generally used in the broad sense to apply to computerized handling of any biodiversity information; the somewhat broader term "bioinformatics" is often used synonymously with the computerized handling of data in the specialized area of molecular biology.

Ocean Biogeographic Information System

The Ocean Biogeographic Information System (OBIS) is a web-based access point to information about the distribution and abundance of living species in the ocean. It was developed as the information management component of the ten year Census of Marine Life (CoML) (2001-2010), but is not limited to CoML-derived data, and aims to provide an integrated view of all marine biodiversity data that may be made available to it on an open access basis by respective data custodians. According to its web site as at July 2018, OBIS "is a global open-access data and information clearing-house on marine biodiversity for science, conservation and sustainable development." 8 specific objectives are listed in the OBIS site, of which the leading item is to "Provide [the] world's largest scientific knowledge base on the diversity, distribution and abundance of all marine organisms in an integrated and standardized format".

A taxonomic database is a database created to hold information related to biological taxa - for example groups of organisms organized by species name or other taxonomic identifier - for efficient data management and information retrieval as required. Today, taxonomic databases are routinely used for the automated construction of biological checklists such as floras and faunas, both for print publication and online; to underpin the operation of web based species information systems; as a part of biological collection management ; as well as providing, in some cases, the taxon management component of broader science or biology information systems. They are also a fundamental contribution to the discipline of biodiversity informatics.

Plazi is a Swiss-based international non-profit association supporting and promoting the development of persistent and openly accessible digital bio-taxonomic literature. Plazi is maintaining a digital taxonomic literature repository to enable archiving of taxonomic treatments, enhances submitted taxonomic treatments by creating version in the XML formats TaxonX and Taxpub, and educates about the importance of maintaining open access to scientific discourse and data. It is a contributor to the evolving e-taxonomy in the field of Biodiversity Informatics.


AquaMaps is a collaborative project with the aim of producing computer-generated predicted global distribution maps for marine species on a 0.5 x 0.5 degree grid of the oceans based on data available through online species databases such as FishBase and SeaLifeBase and species occurrence records from OBIS or GBIF and using an environmental envelope model in conjunction with expert input. The underlying model represents a modified version of the relative environmental suitability (RES) model developed by Kristin Kaschner to generate global predictions of marine mammal occurrences.

AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature can be difficult for researchers who need the old sources for their taxonomic research.

Nomenclator Zoologicus is one of the major compendia in the field of zoological nomenclature, compiled by Sheffield Airey Neave and his successors and published in 9 volumes over the period 1939–1994, under the auspices of the Zoological Society of London; a tenth, electronic-only volume was also produced before the project ceased. It contains over 340,000 published name instances with their authorities and details of their original publication, certain nomenclatural notes and cross references, and an indication of the taxonomic group to which each is assigned. An electronic (digitised) version of volumes 1-10 was released online by the uBio project, based at the Marine Biological Laboratory, Woods Hole, in 2004–2005.
