Abstract

Isolates of the moss Ceratodon purpureus were collected down a channel formed by a meltstream waterfall at Granite Harbour in Southern Victoria Land, Antarctica. The RAPD technique was used to analyse the extent of genetic variation within clumps, between clumps, and between this population and specimens of the same species from two other areas in Antarctica (one a few hundred metres away, the other at Edmonson Point, 300 km further north) and from Sydney, Australia. Genetic variation was detected within and among clumps, with some spatial structure to the population within the channel. Isolates from the nearby location were quite closely related, whereas those from Edmonson Point formed an outgroup on a phylogenetic tree of relatedness.
