Robert Holmes at the Yem'sey River, Russia International Study Shows River Discharge in Arctic Ocean is Increasing Another question investigated microbes in nature. These are responsible for many of the transformations in the carbon and nitrogen cycles that control important ecological processes such as carbon storage and nutrient recycling. This study looked at the link between the structure of the microbial populations in an Arctic lake and seasonal changes. This research, carried out by Byron Crump and John Hobbie of the Center, could only be done with the assis- tance in molecular tech- niques from Mitch Sogin of the Bay Paul Center. New techniques allowed the identification of microbes and species changes, which is the first step towards the long-term goal of linking species to ecological function. The study, the first of its kind for lakes, revealed that there was a resident population of bacterial species throughout the year. However, a distinctly different group of species appeared when large amounts of organic matter entered the lake during the spring meltwater runoff. This organic matter, and perhaps the bacteria, came from the plant litter and soil in the surrounding An Ecosystems scientist collects samples from the Kuparuk River in Alaska Researchers from The Ecosystems Center, along with an interna- tional team of hydrologists and oceanographers, have docu- mented that the flow of freshwater from Arctic rivers into the Arctic Ocean has increased significantly over recent decades. If the trend continues, some scientists predict this could impact the global climate, perhaps leading to the cooling of Northern Europe. Ecosystems Center researchers Bruce Peterson, Robert (Max) Holmes, and James McClelland led the team of scientists from the United States, Russia, and Germany. They analy2ed discharge data from the six largest Eurasian rivers that drain into the Arctic Ocean. The
