The database includes 4724 records of 355 species of benthic invertebrates mostly belonging to phylums Annelida, Arthropoda and Mollusca. The database includes 528 sampling events held in period 2007-2021 in Ukrainian part of Danube delta. Most of the records were carried out on the territory of the Danube Biosphere Reserve. The database includes findings of bottom-living and plant-living benthic invertebrates.
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 528 records.
1 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.
The table below shows only published versions of the resource that are publicly accessible.

BioDATA grant for data mobilization including digitization, data quality assurance, data preparation, and publication of collection specimen and other species data from Ukraine to GBIF. Dataset preparation was supported within the project "Records of macrozoobenthos organisms in the Ukrainian part of the Danube delta during 2007-2021".

The samples of macrozoobenthos were collected three times a year - spring, summer and autumn. Samples were collected from sandy, silt and silty-sand bottom substrates and representatives of aquatic vegetation. Samples were collected by bottom-grabbers (with a working area of 100 cm2), hand samplers (with a working area of 100 cm2), hydrobiological net, kicking net and bottom dredgers. The upper layer of the bottom sediments (up to 5 cm) was selected for the study. The samples were washed through a sieve with a mesh size of 1 mm2, fixed with a 4% formaldehyde solution and transported to the laboratory to determine the species composition. The database contains mostly finds identified to species or genus. Geographical locations were indicated by GPS-navigator in decimal degrees according to the WGS84 system. The nomenclature follows the GBIF BackBone Taxonomy.
|Study Extent||The dataset represents the results of samplings of invertebrates associated with aquatic habitats, made in different water bodies within the Danube River delta (Odesa region, Ukraine) every year from 2007 to 2021.|
|Quality Control||The authors are responsible for the quality of data presented within the published dataset.|
Method step description:
- Conducting regular samplings using the technoque describend in the "Sampling methods" section.
- Collecting of invertebrates for further identification.
- Identification of the collected samples to the level of species or higher taxonomic level.
- Organising of the dataset according to Darwin Core standards.
