Lichens of King George Island, Antarctica
137Cs, 226, 228Ra, 210Pb and 40K concentrations in Antarctic soil, sediment and selected moss and lichen samples
Abstract During the summers of 1986, 1988 and 1992, soil, sediment, lichen and moss samples were collected near the Brazilian Antarctic station, Comandante Ferraz, King George Island, South ShetlandExpand
Short Note: The first appearance and establishment of an alien vascular plant in natural habitats on the forefield of a retreating glacier in Antarctica
. 1985). However, there is no evidencefrom palaeorecords that any other vascular plants existedin this region during the Holocene, despite the fact that amajor source of potential immigrants isExpand
Ecophysiological investigations of Usnea antarctica in the maritime Antarctic I. Annual microclimatic conditions and potential primary production
Spring and autumnal months are revealed as probably the most important periods for lichen primary production because PPFD exceeds photosynthetic light compensation point during the daytime and ambient moisture conditions frequently favour a positive carbon balance. Expand
Testing for endemism, genotypic diversity and species concepts in Antarctic terrestrial microalgae of the Tribonemataceae (Stramenopiles, Xanthophyceae).
The presence of distinctive sequence regions within the psbA/rbcL spacer, together with differences in the rbcL phylogeny, provided significant autoapomorphic criteria to re-define the Tribonemataceae species. Expand
Trace elements concentrations in selected moss and lichen species collected within Antarctic research stations
The Antarctic region has been considered as a region the least exposed to the pollution. However, increase of human activities at the research stations, transportation and tourism threaten theExpand
