| Abstract: | Coastal region on the Antarctic continent, where it is under the influences
both of ocean and ice sheet, as well as frequent human activities, could be considered as
a fragile zone in Antarctic ecological environment. There are many lakes in coastal
region, showing much differences from each other in physical-chemical features because
of individual evolutionary history in their geographical environments, and suffering
from different outside factors, such as climate changes and precipitation. Thus, it
results in respective biological distribution and ecological structure in lakes. The present
paper reports the results from the studies of chemical components, species distributions
and community structures, which mainly consisted of planktons in lakes in the Vestfold
Hills (68°38＇S, 78°06＇E), and the Larsemann Hills (69°30＇S, 76°20＇E), East
Antarctica. It also treats the biological diversities and nutrient relationships of these
different types of lakes. So as to provide more scientific basis for monitoring of climate
changes and environmental protection in Antarctica. |
