Description
| - The ecology of two meltwater streams on King George Island, Ornithologists Creek (with penguin rookeries close to its lower reaches) and Petrified Forest Creek (a highly oligotrophic system), was studied during the 1996-97 summer season. To estimate seasonal productivity of the periphyton and to establish which environmental parameters influenced periphyton growth most strongly, two types of artificial substrata (fibreglass nets - ash-free dry weight (AFDW), and microscope slides - Chlorophyll a (Chl a)) were tested in situ. Thus relative periphyton productivity (RPP) reflects algal colonization and growth as well as losses due to cell mortality and abrasive action of moving sediments. The Petrified Forest Creek was more productive (AFDW = 108.63 mug cm(-1) d(-1), Chl a = 0.35 mug g cm(-2) d(-1)) than the Ornithologists Creek (AFDW = 69.90 mug cm(-2) d(-1), Chl a = 0.26 mug cm(-2) d(-1)). RPP differed both along the streams, and during the season. Significant positive or negative relationships (genera
