Description
This dataset presents morphometric measurements of seeds from seven Rheum L. (Polygonaceae) species collected across Kazakhstan. Seed dimensions, mass, and morphological characteristics were analyzed to identify taxonomically informative traits and assess variation across ecological and geographical contexts. The data support species identification, provide insights into intraspecific variability, and can inform taxonomic and conservation studies of Rheum species in Central Asia. These data are derived from the published study: Sumbembayev et al., 2023, Biodiversitas Journal of Biological Diversity, 24(9), 4677–4692.
Data Records
The data in this sampling event 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 58 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.
Versions
The table below shows only published versions of the resource that are publicly accessible.
