| Abstract | In the McMurdo Dry Valleys (MDV), the permanently ice-covered lakes are unusual aquatic environments that are home to unique communities of microbes. Mats of photosynthetic microbes grow on the floors of these lakes and are an important part of the ecosystems in MDV environments. They experience extreme seasonality that includes the challenge of months of winter darkness. Mats cannot photosynthesize during winter, but they do remain active, and this can impact their ability to respond when sprin |
