Microbial communities in southern Victoria Land streams (Antarctica) II. The effects of low temperat . discs incubated for one month in darkness decreased by 27% at 5 °C, but by 99% at 25 °C. This set of assays suggests that the cyanobacterial mats contained large amounts of chlorophyll . and carbon associated with inactive or senescing cells. This unusual standing stock could probably not persist

Benthic algal biomass and productivity in high subarctic streams, Alaska sestonic chlorophyll . (used as estimates of benthic algal chlorophyll . standing crop) varied directly and significantly with alkalinity among ten clear-water streams; and, with total phosphorus among 8 of 10 clear-water and 5 brown-water streams studied. During the summer, when there is little da

Geochemical processes in the Lake Fryxell Basin (Victoria Land, Antarctica)ws in about three thousand years (chloride age)..Comparison of nutrient concentrations in these meltwater streamsn with other flowing waters in the world reveals that the Frywell streams are strikingly deficient in NO.-N but not PO.-P. The apparent nitrogen deficiency in Lake Frywell itself can be a

Some aspects of iron cycling in maritime antarctic lakess (assuming Fe(III) is not limiting) these should outcompete sulphate reducers and methanogens (both previously reported from Sombre and Amos Lakes) and could therefore constitute an important component of the anaerobic mineralisation of organic carbon in such lakes.

Nitrogen cycling in Arctic lakes and pondst. In the deep lake, . nitrogen regeneration and allochthonous sources are important and nitrogen deftciency can occur..An examination of the nitrogenous nutrient regime of these two systems and the major cycle processes is included.

Patterns of energy storage in , (Crustacea, Copepoda) from two contrasting lakes on Signy Island, Ansociated with an increase in dry weight. Female lipid contents show evidence of two peaks of egg production. In Sombre Lake both male and female copepods increase in size during summer and show a wider range of lipid contents than in Heywood Lake; it is likely that this is due to the poorer winter f

Physico-chemical characteristics and origin of hypersaline meromictic Lake Garrow in the Canadian Hic.Its anoxic monimolimnion is nearly three times (90%0) as salty as normal sea water..This hypersaline water seems to have been derived from isostatic trapped marine waters within thepresent lacustrine basin as well as from underground during deglaciation of the area.
