The samples of river sediments from Postojna Cave System deposited by the Pivka River were analysed for chemical composition and metagenomes. Bacteria belonging to the phyllum Proteobacteria dominated in the samples. Recent sediments were compared to two reference samples, the first that has been deposited during the Middle Quaternary and the second being a karst soil. Alluvial sediments in caves represent a long-term refuge for metabolically diverse microbial lineages, a source of nutrients and microbial re-colonization potential for new ecological niches.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
COBISS.SI-ID: 40164397In the frame of the event Generations of Sciences at ZRC SAZU, where Tanja Pipan received the Golden Award for her scientific research achievements, she presented her work in the field of long-term ecological research on karst and the results obtained in the framework of the research project.
F.27 Contribution to preserving/protecting natural and cultural heritage
COBISS.SI-ID: 11306388The Pivka River which sinks in Postojna Cave is recently subjected to heavy organic pollution of an unknown origin. The karst underground with the Pivka River is an extremely vulnerable habitat in which also Proteus anguinus lives, an endemite of the Dinaric karst and endangered species placed on the IUCN Red List. Therefore it must be protected, as well as the broader catchment area of the Pivka River.
