We propose to study the microbial ecology of the hyporheic and associated arid soils in various McMurdo Dry Valley systems. We want to study the biogeochemistry of these sites and the activity, composition and distribution of the N−fixing communities. Ultimately, we want to map the distribution of these communities throughout the valley ecosystem via a landscape model and extrapolate their influence on total N budgets.
