Kelsey Feser

Dr. Feser focuses her research on using molluscan subfossil remains from shallow marine seagrass environments around St. Croix, in the United States Virgin Islands, to track changes in populations and substrates through time and space. 

She uses both the live and the accumulated dead remains of seagrass-dwelling mollusks to investigate temporal and spatial changes in these environments.  By examining compositional changes (e.g. changes in taxa and their abundances), she addresses questions like: how have these environments changed over hundred - to thousand - year timescales, to what extent to assemblages vary from sample to sample or locality to locality, and to what degree are sediments in seagrass beds mixed.
