Myxomycetes, or slime molds, despite their unassuming name, are fascinating organisms that play a crucial role in forest ecosystems. They live as single-cell amoebae in soil or all sorts of plant debris, where they feed on microscopic bacteria, algae, and fungi. However, when it is time to reproduce and disseminate, these tiny amoebae fuse with each other and form slimy, mobile structures – plasmodia. Plasmodia slowly but actively crawl on the substrate, and eventually transform into fungi-like fruiting bodies filled with spores. Both plasmodia and fruiting bodies are visible with the naked eye and can be easily found e.g. on decaying wood or on the forest floor.
Myxomycetes are unusual in their life cycle and very eye-catching – if only one knows where to look for them. No wonder that they have attracted the attention of naturalists for centuries. On the territory of Ukraine, observations of myxomycetes first appeared in the first half of 19th century and have been occurring sporadically in the mycological literature ever since.
However, much valuable information about the myxomycetes of Ukraine before our study was in a “grey zone”. This includes undigitized historical books and articles published in languages such as Polish, French, or German. Furthermore, there is a significant body of proceedings of local conferences, articles in local journals, and reports produced by the employees of protected areas. Yet, many of these publications existed only in print and were written in the Cyrillic alphabet, so they remained difficult to discover, to access, or to work with.
Within this study, published in Biodiversity Data Journal, we aimed to summarize all published research on myxomycetes of Ukraine, which spans over 150 years, and make the data, as well as the literature behind the data, open and easy to use. For this, we collected and mined 91 publications on this topic, spanning the years 1842 to 2023. As the result, we extracted over 5000 occurrences of myxomycetes that belong to 331 species. The produced datasets we published on GBIF, and the major part of the literature sources on the platform Zenodo.org in open access.
With this initiative, we aimed to open to the wider audience and digitally preserve some part of the biodiversity data heritage of Ukraine that is currently under threat of destruction.
This study was substantially driven by the BioDATA project, which helped a lot in developing biodiversity data management skills in our team.
