Indian Ocean Islands - Historic Freshwater Diatom Data

Latest version published by BioFresh on Aug 26, 2019 BioFresh

The data collection contains species occurrence records of freshwate diatom taxa from the Indian Ocean Islands (Madagascar, Mauritius, Seychelles). The species records have been collated from existing historical museum records and collections as well as from published scientific literature sources. The data set is a work in progress and more data will be added to it over time. The focus initially will be on Madagascar, followed by the smaller islands in no particular order.

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 333 records.

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.
