The Sea as major source of ions to lichens in terrestrial ecosystems of Victoria Land
Entry ID: Ions_to_lichens_Victoria_Land

[ Update this Record ]

Summary
Abstract: Lichens and mosses constitute the bulk of plant biomass in terrestrial
ecosystem of continental Antarctica. On the hypothesis that cryptogams can be
used as an early warning system to detect the effects of climatic changes on
environmental biochemistry, we investigated the elemental composition and the
main source of soluble ions to the saxicolous lichen Umbilicaria decussata in
Victoria Land. ... View entire text

Quality U. decussata samples were collected from rock outcrops representing the main
regional lithological features. To estimate the bioavailability of ions in
lichen substrata, two filter papers were laid for five minutes on rock surface
near Umbilicaria stands and wet with 3 ml of deionized water. Whenever
possible, 2 filters were also put on salt encrustations and sample of
