My research focuses on the invasive crab Hemigrapsus sanguineus and its impact on the crustacean-eating
guild of fishes in Long Island Sound. For the past fifteen years, consideration of the potential ecological impacts of the invasive
crab H. sanguineus was limited to intertidal habitats. Recent observations demonstrate the expansion of the species into
shallow subtidal habitats in Long Island Sound where it has the potential to impact the crustacean-eating guild of fishes through
direct and indirect interactions.
My main research objectives are to determine if H. sanguineus is adversely affecting the food resource for economically
important fishes in Long Island Sound, and to determine the impacts of the crab on the food web dynamics
of crustacean-feeding fishes. Understanding how the communities respond to changes in food web structure (i.e. predator or prey
population increases or declines) is vital to the management of our region's coastal fisheries.
