What can seascape-scale vegetation patterns on coral reefs tell us about reef health?

PI: Elizabeth Madin
Coral reefs worldwide are threatened by changing conditions yet are often remote and hard to monitor. This project will use drone-based imagery to explore how coral “halos” are linked to reef ecosystem health, and whether that health may change over time where protective measures are instituted.

Resolving the Diet of Larval Marine Fishes to Accelerate Aquaculture Opportunities

PI: Brian Bowen
Demand for sea food increases while wild stocks dwindle, but marine aquaculture efforts struggle to raise fish larvae due to their highly selective, yet undetermined, food preferences. This project applies innovative DNA barcoding of larval intestinal contents to determine typical diets and thus enhance aquaculture opportunities to provide sustainable fish stocks.

Land-based pollutants on Hawaiian reefs

PI: Megan Donahue
Increased military, agricultural, and residential development contaminates surrounding watersheds that feed into critical coastal ecosystems. This work examines land-based pollutants, such as metals and persistant organics, in coastal ecosystems and reef fish to understand how the pollutants are distributed and transported, with an eye toward better land management decisions.
