Abstract

In 2023, a scientific project for studying the fungal biodiversity in organogenic soils in the area of the Bulgarian Antarctic Base &amp;lsquo;St. Kliment Ohridski&amp;rsquo; on Livingston Island was funded by the National Center for the Polar Studies at Sofia University &amp;lsquo;St. Kliment Ohridski&amp;rsquo;, implemented under the National Program for Polar Research &amp;lsquo;From Pole to Pole&amp;rsquo;, adopted by the Ministry of Education and Science.&amp;nbsp;<br> In the period February-March 2023, a total of 126 soil samples were collected for analysis. Soil samples were carried out in the upper 0-5 cm soil layer. In places with deeper soil profiles, samples were collected from the deeper layer &gt;5 cm. All samples were stored in sterile polyethylene bags in a freezer at minus 28&amp;deg;C on the Bulgarian ship &amp;lsquo;St. St. Cyril and Methodius&amp;rsquo;, which arrived in Bulgaria on 2nd May 2023.<br> The present study aims to present the conceptual basis for the study of structure, composition, and bioecological features of fungal species occurring in Antarctic organogenic soils from Livingston Island, to investigate the representatives of separate taxonomic groups of invertebrate organisms interacting with the fungal species in the soil, and to establish the relationships with the soil characteristics in the studied sites. Studies of the biological and ecological features of representatives of the mycota in Antarctic organogenic soils, their physiological and biochemical behavior, and interaction with invertebrate organisms, are essential for a better understanding of the biological processes occurring in them, and the implementation of this project will have substantial contribution to these issues.
