Dr. Sarah Nelson, assistant research professor at the University of Maine, is working with parks in the eastern United States collecting dragonfly nymphs, and sending them to a lab for mercury analysis. She started her work in Acadia National Park (in Maine) using students and teachers to successfully collect the nymphs. She is now expanding her work to other National Parks including Great Smoky Mountains National Park. The ongoing research is investigating whether the dragonfly nymph's size, taxonomic family, or other factors explain part of the spread in the data.
