Hannes Baumann (PI)


Hannes Baumann started the ‘Evolutionary Fish Ecology’ Lab in September 2014 to expand ecological and evolutionary frontiers via experimental, field, and modeling work. His work focuses on the central question, how coastal marine organisms will cope with the simultaneous changes in their environment caused by global and regional human activity, and how they are already adapted to environmental variability in e.g. temperature, oxygen, or pH.

Local field work includes maintaining deployed sensors, frequent collections with plankton nets and beach seines, in addition to laboratory rearing of fish, physiological measurements, and otolith microstructure analysis – all of which can incorporate the help of interested and ambitious undergraduate students searching for hands-on experience and own projects.

Emma Cross (Post-doctoral researcher)


Emma Cross joined our team in September 2017, after receiving her PhD from Cambridge University, UK, in August 2016. Her previous work focused on the CO2-sensitivity of polar and temperate brachiopods, a group of ancient, sessile calcifiers that build large shells but are unrelated to mollusks. In addition to experimental approaches, she examined historical collections of specimens from New Zealand. Her findings suggest that brachiopods can cope with acidifying oceans by compensating for increased shell dissolution by increased shell thickness. Emma now transitions to working with fish, particularly Atlantic silversides, testing how fluctuating pH and oxygen environments typical of nearshore environments affect early life survival and growth.

Callie Concannon (MS student)

Callie Concannon started in fall 2018 as a master student in the Baumann lab after getting an excellent bachelors degree from the University of Massachusetts in Dartmouth. She is going to use otolith microstructure analysis in juvenile silversides to contribute individual-based data to our NSF project aiming to elucidate the genomic underpinnings of local adaptation in the Atlantic Silverside. Welcome, Callie!

Lucas Jones (MS student)

Lucas Jones will start in summer 2019 as a master student in the Baumann lab after getting his bachelors degree from the University of Connecticut. Lucas started out as a volunteer in our lab 2017 and because of his dedication and experimental talent quickly became an indispensable asset to our scientific operations. He will now continue to leverage his familiarity with our rearing system to further investigate the climate sensitivity and population characteristics of Northern sand lance (Ammodytes dubius), an important winter-spawning forage fish in the Gulf of Maine. Welcome, Lucas!

Deanna Elliott (NSF REU student)

Deanna Elliott is a junior at Arizona State University who has joined the Baumann lab in summer 2019 as our third NSF-REU student. Deanna has experimented with locusts before, but now strives to become an expert fish rearer. Her project will rear Atlantic silverside larvae under different feeding regimes to create fish of different body sizes and then analyze the these fish for trace levels of mercury in their tissue. She will test the hypothesis that mercury concentrations in fish can be used as a proxy for ingestion rates, which are important to trophic ecosystem models to perform better. Welcome, Deanna!
