Zajímavé nálezy vzácných mechorostů ve starých sedimentech 2

Old peat deposits represent a natural archive of past species occurrences. Frequently, remains of bryophytes are especially well preserved in peat deposits, including fens, and can often be identified to the species level. During ongoing research in the Western Carpathians and the Morava river valley, we discovered new sites where the relic fen species Drepanocladus sendtneri, D. trifarius, Meesia triquetra and Scorpidium scorpioides occurred in the Late Glacial and Holocene periods. Moreover, remains of six epiphytic bryophyte species were also recorded in one carbonate sediment of Early-Holocene age in southern Slovakia. Fossil records of epiphytic bryophytes are rather unique and rare in fen deposits.
