INFORMATIONFACILITY GLOBALBIODIVERSITY An Index of all genera David Remsen and David Patterson TDWG, Bratislava September, 2007 WWW.GBIF.ORG
All Genus Index: What it is • A federated catalog of all genus names • Past and present • Includes • Currently (VALID | AVAILABLE) • Unavailable/Invalid genera, misspellings • Genera with no current nomenclatural standing • All species combinations include a genus
All Genus Index: What it isn’t • Is NOT itself an authoritative database(But it IS informed by authoritative databases) • Is NOT a list of taxonomically Valid|Accepted genera
All Genus Index: Why • Identify all “homographs” (i.e., homonyms in the broad sense) • Identify genera missing from existing nomenclators To enable informatics devices: • Disambiguation of homonyms/homographs • Provisionally place “orphan” species combinations • What nomenclator should treat them? • What taxonomic area do they fall under?
All Genus Index: Why • To identify all HOMOGRAPHS How many Oenanthe are there?
All Genus Index: Why • ALL species names include a genus Stegomyia aegypti (L.) Stegomyia
Unite under a “convenience” hierarchy • NOT a taxonomic classification!
Homonym disambiguation 5 Oenanthe 2 choices Nomenclators identify two
Organization framework for species names • ALL species names include a genus Stegomyia aegypti (L.) Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Diptera Genus: Stegomyia Enables: • There is one Stegomyia • It is a fly • It isn’t in the BDWD • Alert Chris Thompson

Genera • Every species combination is anchored to a genus • Index all genera names • Provisionally catalog in a “convenience” hierarchy • Cross-reference to authoritative sources • Develop homograph/homonym disambiguation methods • Organizational device to all combinations
