Fish Flow: Filling the gap between spawning and settlement

PI: Brian Bowen
This project aimed to track reef fish, using their genetic data, from where they spawned as larvae to where they settle on the reef, as a direct measure of population connectivity. Engaging student volunteers, the research team collected over 1500 samples of three target species across the Hawaiian islands. Using advanced genetic technology and computer-aided population connectivity texts, the team generated maps that illustrate that most adult reef fish in Kāneʻohe Bay originate from neighboring East Oʻahu reefs rather than from inside the bay, useful information for appropriate managers.

Predicting Hawaiʻi water demand under climate change

PI: Michael Roberts
This project studied how climate change may affect future water demand on Oʻahu, focusing on variations in temperature, precipitation, and prevailing climatic conditions. Results imply that microclimates play an important role in demand, with the hot and dry area households using typically 100 gallons more per day than those in cooler, wetter aras. Using water billing data cross-referenced with fine-scale weather data, a model was developed that estimates the growth of Oʻahu aquifer yields needed to satisfy possible shifts in demand (up to 50% increase) under different climate scenarios, or alternatively, the price increases necessary to limit consumption levels.
