Antarctic cyanobacteria form microbial mats in perennially ice-covered lakes in the McMurdo Dry Valleys, Antarctica. These mats demonstrate a variety of ecological and metabolic behaviors consistent with Antarctic conditions as well as specific challenges between and within the lakes. In this thesis...
