Biological Sciences

Explore the Department of Biological Sciences

Our focus is on organismal biology in the basic and applied sciences, encompassing physiology, behavior, ecology, and evolutionary biology. Faculty in our department study a wide range of organisms from freshwater, marine, and terrestrial ecosystems. Our location near the Atlantic coastline and the White Mountains provides numerous opportunities for field-based research. The Jackson Estuarine Laboratory, located nearby on Great Bay, and Shoals Marine Laboratory, located on the Isles of Shoals, are valuable resources for students in the Marine and Freshwater Biology program. Collaboration with Cooperative Extension and the Agricultural Experiment Station allows for terrestrial ecological research within farm and forest systems.

  • For my master’s thesis I am looking at the effects of ocean acidification on winter flounder (Pseudopleuronectes americanus). I will be studying how the morphology of winter flounder inner ear bones, otoliths, change under acidified ocean scenarios. And since the otolith is associated with fish...

  • My master thesis research is trying to determine the salinity tolerance of juvenile lumpfish, so that they may be used for different species in the aquaculture industry as a 'cleaner fish'. The second part of my thesis is looking at the spatial and temporal distribution of juvenile lumpfish in the...

  • My research is focused on examining how stress and the stress hormone, cortisol, impacts sex differentiation in black sea bass (Centropristis striata). Black sea bass are popular recreational and commercial marine species whose culture has been hindered  due to the rapid, unnatural sex change that...

  • My thesis project has three objectives: (1) develop and utilize a reliable protocol for the transformation of Dunaliella, (2) see if nitrogen starvation accumulates more lipids, and finally (3) see if more nitrogen sequestration in polyamines also induce lipid production. Nutrient availability has...
