Genetic diversity and dispersal of the moss Sarconeurum glaciale on Ross Island, East Antarctica

Skotnicki, Mary; Ninham, J; Selkirk, Patricia M


The extent of genetic variation and dispersal mechanisms were investigated over short distances of 1-100 m, and up to 3 km, by the random amplified polymorphic DNA (RAPD) technique, for the moss Sarconeurum glaciale, at three locations on Ross Island, Antarctica. At Arrival Heights, genetic variation occurred within single colonies, and the relationships between clumps indicated that they were dispersed down small, meltwater drainage channels by water. The genetic similarities between the...[Show more]
