Amelia MacDonald is assessing the impacts of invasive green crabs on the mudflats of the upper Bay of Fundy. The European green crab is very invasive and has altered the ecological balance of many eco-systems where it has established populations. This crab was recently found in parts of the Bay of Fundy, raising concerns for local ecosystems, including invertebrates, flatfish, and migrating shorebirds. MacDonald’s field research will help determine if there is an established breeding population and give biologists a better understanding of the current status of green crabs, potential effects of this species, and resource management in the upper Bay of Fundy. MacDonald is the recipient of an NSERC undergraduate student research award and is completing her work with biology professor Dr. Diana Hamilton and adjunct professor Dr. Dave Drolet from the Department of Fisheries and Oceans.
