Abstract

Our focus for this project is to determine how the population densities of Hemigrapsus sanguineus, Asian shore crab and Carcinus maenas, European green crabs have shifted over a brief period of time. We are comparing data collected on September 17, 2018, to data collected on October 22, 2018. The location where the two sets of data were collected from is Kettle Cove, Cape Elizabeth, Maine. The GPS coordinance was 43°.33.55N70°.13.40N. We discuss what affects the influences of environmental factors such as temperature, salinity, high intertidal versus low intertidal, and percent ascophyllum cover affect have on the population densities of these two invasive species.
