Research Questions: How do populations of Asian shore, European green, and native crabs compare up and down the coast of the Gulf of Maine? Are crab populations changing over time and in response to warming temperatures? Where will Asian shore, European green, and native crabs be most abundant in the future?

Why this matters

New species of crabs have been introduced to the intertidal zones across the Gulf of Maine disrupting the ecosystem. We need more data to understand how these populations are changing and where they could have the greatest impact in the future.
