ChromoDB: chromosome counts database for vascular plants

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 206,378 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

The dataset has global geographic scope. Geographic information refers to the reported origin of the material studied in the original chromosome-count publications, when available. Records with unclear or problematic geographic origin are excluded from this first GBIF release.

Taxonomic Coverage

This dataset covers vascular plants. The first GBIF release includes chromosome-count records for selected taxa whose names and bibliographic sources have been reviewed in ChromoDB.

Project Data

ChromoDB is an ongoing project aimed at compiling, curating, and publishing chromosome-count data for vascular plants from scientific literature.

Sampling Methods

Data were not generated through direct field sampling. Records were compiled from published chromosome-count studies and bibliographic sources. Each record corresponds to a chromosome-count report associated with a taxon, a reported geographic origin when available, and a bibliographic reference.

Method step description:

1. 1. Chromosome-count records were extracted from published scientific literature. 2. Taxon names were reviewed and linked to accepted names when possible. 3. Chromosome numbers were recorded as n and/or 2n according to the original source. 4. Geographic origin of the studied material was recorded when explicitly reported. 5. Bibliographic references were checked and standardized when possible. 6. Records considered problematic or insufficiently documented were excluded from this first GBIF release.
