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

Feature Story - Fall 2015

Spaghetti’s on the menu in the Galapagos with the discovery of the spaghetti bryozoan in Tortuga and Franklin's Bays

Smithsonian researcher Linda McCann first discovered spaghetti Bryozoan (Amathia verticillata) in the Galapagos Islands in 2015, near the town of Puerto Ayora on Santa Cruz Island. She was participating in the first International Workshop on Marine Bioinvasions of Tropical Islands at the Charles Darwin Research Station at the time. Additional surveys were undertaken by several additional scientists attending the workshop, which turned up more of the introduced bryozoan in Franklin’s Bay, a second small embayment just outside of Puerto Ayora. The potential for impact of the spaghetti bryozoan and other invaders to this world heritage site is of considerable concern and was a major focus of the recent workshop in Puerto Ayora.  Full Story
