Genetic diversity in the moss Pohlia nutans on geothermal ground of Mount Rittmann, Victoria Land, Antarctica.
Entry ID: GeneticDiversity_Victoria_Land

[ Update this Record ]

Summary
Abstract: The only known population of the moss Pohlia nutans in continental Antarctica
occurs on geothermally heated ground of volcanic Mt. Rittmann in northern
Victoria Land. Colonization of this bryophyte is due to peculiar environmental
characteristics of the geothermal ground, because mosses do not normally grow
in Antarctica at such elevations. Specimens from several moss patches within
two sites of ... View entire text

Quality Small samples of P. nutans colonies were collected in three different sites
near a caldera rim of Mt. Rittmann. Specimens were collected in sterile tubes
and then frozen until used for genetic analysis.

In Italy DNA was extracted and amplified in RAPD reactions by PCR. After a
period of incubation the reactions were electrophoresed through 1.5% agarose
gel, stained in ethidium bromide and photographed under UV light.
