A Holocene moss species preserved in lake sediment core and the present moss diversity at Schirmacher Oasis, Antarctica
Abstract The sub-fossil moss Pohlia nutans is recorded from lake sediment cores at Schirmacher Oasis, Dronning Maud Land, Antarctica. It was isolated from 160–162 cm depth of a sediment core. Radiocarbon ( 14 C) dates by accelerator mass spectrometry confirmed its age to be 10.65 kyr bp . The preser...

Summary: | Abstract The sub-fossil moss Pohlia nutans is recorded from lake sediment cores at Schirmacher Oasis, Dronning Maud Land, Antarctica. It was isolated from 160–162 cm depth of a sediment core. Radiocarbon ( 14 C) dates by accelerator mass spectrometry confirmed its age to be 10.65 kyr bp . The preserved Holocene sub-fossil moss includes delicate leaves, axes and rhizoids and matches perfectly the extant specimens of P. nutans. This is the first record of this sub-fossil from Dronning Maud Land, although the species is common as present-day flora in other parts of the Antarctic. The present status of the moss flora of Schirmacher Oasis is also discussed, including its diversity, ecology and biogeography. |
