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

Molecular Data Leads to Surprising Discoveries about Oysters in Panamanian Waters

Dr. Katrina Lohan and her colleagues used a combination of morphological and molecular data to determine the distribution of oysters in Panama. They collected and identified ten bivalve species and made two important and unexpected discoveries. First, the eastern oyster (Crassostrea virginica) occurs on the Caribbean side of Panama where it lives in close contact with another closely related species, the mangrove oyster (C. rhizophorae). Second, a non-native species of oyster, the hooded oyster or Natal rock oyster (Saccostrea “cucullata”) from the Indo-Pacific Ocean, was found in multiple locations along the Caribbean coast of Panama. Both oyster species were previously unknown from Panama, and these discoveries are detailed in their latest paper in the journal Marine Biology.  Full Story
