About the Lab 

The Marine Invasions Research Lab is a national and international center for research on biological invasions in coastal marine ecosystems. Biological invasions (the establishment of species beyond their historical range) are a major force of ecological and evolutionary change. Invasions are fundamentally changing the structure and function of ecosystems around the world and are impacting many dimensions of human society. The observed rates and impacts of new invasions have increased dramatically in recent time. ...more

Could Expanding the Panama Canal Increase the Risk of Invasion?

The most recent expansion of the Panama Canal is scheduled to open in 2015. A third set of locks, plus widening and deepening of existing channels is expected to double the cargo capacity of the canal, allowing transits of more and larger vessels. The expansion of the canal has prompted major infrastructure changes at eight US ports. Dr. James Muirhead and others have developed a series of scenario-based models to explore how this project could impact the transfer of invasive species to the United States. Full Story
