Seasonal changes in the photosynthetic and photoprotective pigment content of three species of Antarctic moss; Grimmia antarctici…
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)…
A group of strains with potent extracellular enzymic activity were isolated from the surfaces of the chain-forming sea-ice diatom Melosira and from an unidentified macrophyte collected from the Eastern Antarctic coastal zone.
The growth rates of heterotrophic nanoflagellates (HNAN), mixotrophic cryptophytes, dinoflagellates and ciliates in field assemblages from Ace Lake in the Vestfold Hills (eastern Antarctica) and Lakes Fryxell and Hoare (McMurdo Dry Valleys, western Antarctica)…
Quartz stone sublithic cyanobacterial communities are common throughout the Vestfold Hills, Eastern Antarctica (68 degrees S 78 degrees E) contributing biomass in areas otherwise devoid of any type of vegetation. In this study…
