Ecosystem dynamics and temporal variations in a microbially dominated, coastal antarctic lake: Author: Dieser, Markus; Date: 2009-12-15; Program: Ecology and Environmental Sciences; Abstract: This study investigated the microbial ecology of Pony Lake, Antarctica. The main objectives of this research were to 1) characterize physicochemical parameters in Pony Lake during the transition from ice covered to ice free, 2) highlight seasonal and inter-seasonal alterations in lake parameters, 3) relate the physicochemical conditions in the ice and water column to microbial processes and community structure, 4) characterize the effects of phototransformation of dissolved organic matter (DOM) on its bioavailability to bacteria, and 5) demonstrate the role of carotenoid pigments in protecting...; Download File | View full details
