Blake’s thesis research focuses on describing food webs around tropical Pacific Islands, particularly how coastal environments like coral reefs are trophically connected to the deep sea. He uses compound-specific stable isotope analysis and DNA metabarcoding to identify coastal zooplankton in the diets of deep-sea micronekton (small fishes, shrimps, and squids) around the Hawaiian Islands. This information will be used to inform coastal and deep sea conservation policy, as well as to better parameterize ecosystem models that are used to predict catch rates of bigeye tuna and swordfish.
Blake was awarded a grant to pay for indexing costs in the DNA metabarcoding process that will be used to identify distinctly reef-associated zooplankton from the Hawaiian Islands!
