Novus steering committee member Kendra McLauchlan (Kansas State University) and colleagues recently published a study of the sedimentary record of Devil’s Lake, Wisconsin. The team obtained a 10-meter core from Devil’s Lake, dating back 28,000 years, making this the longest paleoecological record in the northern United States. The study highlights a series of six lithological and ecological phases which incorporate changes in lake productivity, alterations of the fire regime, shifts in terrestrial vegetation, and anthropogenic influences on ecosystem nutrient cycling due to agricultural activities.
