Dr. Byron Crump has worked in the Arctic for over a decade exploring the biodiversity and ecology of bacteria and other microbes in lakes, streams and soils. Microbial communities are essential components of every ecosystem on the planet, and in recent years we have learned that the most abundant organisms in natural microbial communities are unrelated to the cultured organisms studied in the lab for the last 100 years. Microbial communities contain an extremely deep diversity and an immense genomic potential of novel functional genes. Dr. Crump is currently conducting a multi-year study of microbial community composition and growth rate in arctic lakes and streams on the North Slope of Alaska to measure how diversity and growth vary over time and are affected by global change.
