The GBIF Backbone Taxonomy is a single, synthetic management classification with the goal of covering all names GBIF is dealing with. It's the taxonomic backbone that allows GBIF to integrate name based information from different resources, no matter if these are occurrence datasets, species pages, names from nomenclators or external sources like EOL, Genbank or IUCN. This backbone allows taxonomic search, browse and reporting operations across all those resources in a consistent way and to provide means to crosswalk names from one source to another.

It is updated regulary through an automated process in which the Catalogue of Life acts as a starting point also providing the complete higher classification above families. Additional scientific names only found in other authoritative nomenclatural and taxonomic datasets are then merged into the tree, thus extending the original catalogue and broadening the backbones name coverage. The GBIF Backbone taxonomy also includes identifiers for Operational Taxonomic Units (OTUs) drawn from the barcoding resources iBOL and UNITE.

International Barcode of Life project (iBOL), Barcode Index Numbers (BINs). BINs are connected to a taxon name and its classification by taking into account all names applied to the BIN and picking names with at least 80% consensus. If there is no consensus of name at the species level, the selection process is repeated moving up the major Linnaean ranks until consensus is achieved.

UNITE - Unified system for the DNA based fungal species, Species Hypotheses (SHs). SHs are connected to a taxon name and its classification based on the determination of the RefS (reference sequence) if present or the RepS (representative sequence). In the latter case, if there is no match in the UNITE taxonomy, the lowest rank with 100% consensus within the SH will be used.

Note: this dataset was previously orphaned. It has been rescued by ① extracting it from the GBIF.org index (see GBIF Download in External Data) and ② republishing it on this IPT data hosting centre as version 1.0.

This dataset contains occurrence data of flora and fauna species. From the Netherlands on a 5 x 5 km scale, data from other countries are exact. Observations from Belgium are excluded and can be accessed on GBIF through Natuurpunt and Natagora. It summarizes the observations recorded by >175.000 volunteers.

Sierra Nevada mountain range (southern Spain) hosts a high number of endemic plant species, being one of the most important biodiversity hotspots in the Mediterranean basin. The high-mountain meadow ecosystems (borreguiles) harbour a large number of endemic and threatened plant species. In this data paper, we describe a dataset of the flora inhabiting this threatened ecosystem in this Mediterranean mountain. The dataset includes occurrence data for flora collected in those ecosystems in two periods: 1988-1990 and 2009-2013. A total of 11002 records of occurrences belonging to 19 orders, 28 families 52 genera were collected. 73 taxa were recorded with 29 threatened taxa. We also included data of cover-abundance and phenology attributes for the records. The dataset is included in the Sierra Nevada Global-Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this area.

The Denver Museum of Nature & Science Mammal Collection currently consists of approximately 21,000 specimens, which includes 20,000+ cataloged specimens. The collection spans 1870 to the present, is worldwide in coverage, and includes specimens from the three major extant mammalian lineages (monotremes, marsupials, and placentals) distributed across 21 orders, 266 genera, and 381 species. The collection’s primary strength is its focus on the southern Rocky Mountains and Great Plains. Approximately 82% of the collection is from the western United States, with specimens from Colorado (73%) representing the largest percentage. Small mammals, such as shrews, rodents, lagomorphs, and bats, constitute the majority (84%) of specimens in the collection. The composition of the collection is primarily study skins and skeletal material, with a growing wet collection. High-quality specimen data, frozen tissues, and parasites are associated with most of the specimens archived since 2006.

The Fish Collection at the Auburn University Museum of Natural History has fishes from all over the world. The collection has particularly large holdings of fishes from the Southeastern US and South America. Approximately 750,000 preserved specimens in more than 72,000 lots are cataloged in the collection.

Specimen data for amphibians

The vertebrate paleontology program at the University of Kansas has, for over a century, sustained a national and international reputation. The reputation of the collection has been based more on intensive use than on sheer size. We now hold over 150,000 cataloged specimens (>75,000 are available in digital format) and around 400 publications related to our collections have been published in the last 35 years. Research strengths include: Paleozoic and Mesozoic fishes, Paleozoic tetrapods, Mesozoic marine vertebrates, Cenozoic small mammals and Natural Trap Cave fauna.
