Measurements of salinity, temperature, phytoplankton biomass, and speciation, dissolved nitrate, dimethylsulphide (DMS) in seawater and air, and dimethylsulphoniopropionate (DMSP), were made in the subantarctic zone of the Southern Ocean from 40-54oS…
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 morphological diversity of naturally occurring populations of the chroococcoid cyanobacterial genus Synechococcus were investigated by electron microscopy. Analysis of samples from a coastal Tasmanian site (38° S 148° E) and from south of the Sub Tropical Convergence (54°S 146°E)…

Weddell seals (Leptonychotes weddelli) are the most southerly breeding of all mammals and breed on the fast-ice around the shores of the Antarctic continent. Weddell seals display a polygynous mating system, with operational sex ratios (OSR) ranging from 3:1 to 8:1.
