What Are They Doing?
To date, the researchers have found that microbial communities in lakes and rivers change dramatically through the seasons but reassemble on an annual basis. They have also found that community composition in soil and surface waters shifts within days in response to environmental fluctuations in temperature or dissolved organic matter composition. They have also found that upland terrestrial habitats act as landscape-level seedbanks for lowland aquatic systems. The ultimate goal of the project is to develop a greater understanding of the controls on microbial community composition and function over space and time.

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.
