Shortnose sturgeon (Acipenser brevirostrum) are a federally listed endangered species native to the east coast of the United States and Canada. In the Gulf of Maine, demographic connectivity among coastal river systems is common, though little is known about the population level consequences of such connectivity. My doctoral research aimed to elucidate such consequences and did so through a combination of field, (ultrasonic telemetry, mark-recapture), laboratory (dorsal scute microchemistry), and theoretical (life-history modeling) techniques.
This research is being continued in the labs of Dr. Gayle Zydlewski and Dr. Michael Kinnison at the University of Maine. Exciting developments are on the horizon as the removal of two mainstem dams on the Penobscot River (Great Works & Veazie dams) has opened up habitat previously unavailable for more than 100 years.
