We are using techniques of molecular genetics to investigate the extent of genetic diversity in Antarctic mosses. The RAPD technique has proven especially useful in demonstrating that these mosses exhibit extensive genetic variation (levels being similar to those in temperate regions)…
The RAPD technique (Random Amplified Polymorphic DNA) was used to assess the level of genetic diversity in Bryum pseudotriquetrum from Southern Victoria Land, Antarctica. Isolates were collected from two transects…
A detailed study was made of the extent of genetic variation within populations of two moss species, Bryum argenteum and Henediella heimii, from the Garwood Valley in Southern Victoria Land, Antarctica. RAPD technology was used to analyse over 30 clumps of each species…
The RAPD technique (Random Amplified Polymorphic DNA) was used to assess the level of genetic diversity in Bryum argenteum from Ross Island and Southern Victoria Land, Antarctica. Samples were collected from three transects at different sites…
We are using molecular genetics techniques to investigate (a) the overall level of genetic diversity in Antarctic mosses, (b) the spatial arrangement and mutation levels within populations, (c) their taxonomic relationships and origins, (d) the effect of climate change on mutation levels, and (e)…
The extent of genetic variation and dispersal mechanisms were investigated over short distances of 1 – 100 m and up to 3 km, by the RAPD technique, for the moss Sarconeurum glaciale at three locations on Ross Island, Antarctica. At Arrival Heights, genetic variation occurred within single colonies…
Bryum argenteum sensu lato is a cosmopolitan moss found in many countries of the world, and is one of only a few moss species present in continental Antarctica. We have used RAPD (Random Amplified Polymorphic DNA) technology to investigate how this moss has colonised and spread in Antarctica…
