Dr. Mykle Hoban is a molecular ecologist interested in fundamental questions about marine biodiversity: Why are there so many species? Where do they come from? Why are they found in the places that they are? He has become especially interested in how these questions may be answered in new and unexplored habitats in the sea, particularly the deepest parts of coral reefs, or mesophotic coral ecosystems. These ecosystems, which are found from approximately 30 to 150 m (100–500 ft) depth along tropical coastlines, may actually contain the majority of existing reef habitat, but they are still poorly understood. Mykle’s research applies both traditional (e.g., visual surveys and specimen collection) and molecular (DNAbased) approaches to try to understand these still mostlyunexplored habitats.
