Microbial biogeochemical cycling across a chronosequence of mangrove introductions across Hawaiʻi

PI: Rosanna Alegado
Invasive mangroves harm Hawaiian coastal ecosystems, choking native plants, providing footholds for invasives, and generating leaf litter mounds inedible to Hawaiian species. This study investigates whether microbial communities can evolve to tackle the detritus and examines the resilience of our coastal ecosystems to mangrove invasion.

Effects of watershed restoration to traditional Hawaiian land use practices on health of nearshore coral reef ecosystems

PI: Robert Toonen
Reimplementation of traditional practices in the Heʻeia ahupuaʻa, in addition to invasive mangrove removal, has been predicted to support improvements to the coastal ecosystems of Kānoʻohe Bay. This study will examine effects on water quality and changes to coral reef health, in response to restoration efforts.

Ola I Ka Wai Water is Life

by Lurline Wailana McGregorI ka wā kahiko (in ancient times), before western contact in Hawaiʻi, there was no such thing as private ownership of the land or water or any other natural resource that gave life to the people. Such ...

Huli ‘ia: Observing the Changing Landscape

by Pelika Andrade Huli ‘ia is an observational process documenting seasonal changes and shifts across entire landscapes, ma uka to ma kai (from the mountains to the ocean). Developed by Na Maka o Papahānaumokuākea, the Huli ‘ia process documents these ...

The Return of Kū‘ula: Restoration of Hawaiian Fishponds

by Josh McDaniel According to Hawaiian moʻolelo (oral traditions), Kūʻula built the first Hawaiian fishpond, or loko iʻa, on the island of Maui. Kūʻula was a fisherman of rare skill who is described as having supernatural powers for directing and ...

Voyages of Rediscovery and Discovery

by Randolph Fillmore Thousands of years ago, people indigenous to the Pacific Islands traveled in large sea-going canoes, covering huge expanses of ocean. Exploring, trading, and settling newly found islands, including today’s Hawaiian Islands, these people carried their culture with ...

Puakea: The Consummate Kumu

by James Brancho Dr. Puakea Nogelmeier retired from the University of Hawaiʻi at Mānoa in May after 35 years in front of the classroom. A dedicated teacher with high expectations, he worked throughout educational settings in Hawaiʻi to foster a ...

Book Review: Kaiāulu Gathering Tides

by Jackie Dudock The tide is rising ahead of the early morning sun on the northeast coast of the Hawaiian island of Kaua‘i. Waves rush singing onto the outer reef where two throw net fishermen stalk the surge. An elderly ...

Podcast #2: Loko iʻa

Meet Dr. Rob Toonen and Kaleonani Hurley and hear about their study of historical harvesting practices of crab populations in Hawaiian fishponds (or loko i'a) and the applicability to today's management practices. Read more about their project here ...

Hehihehi management for microbial-mediated sediment removal in fishponds

PI: Kiana Frank
This study employs the modern tools of microbiology to examine the efficacy of a traditional management tool applied to today’s fishpond restoration efforts. The researcher is examining whether microbes may decompose pond-clogging sediment faster if aided by hehihehi, the traditional practice of stomping and mixing of the fishpond sediment.

Integrating climate science with local knowledge through community vulnerability assessment on Kauaʻi

PI: Daniele Spirandelli
This study examines the opportunities and challenges of integrating coastal resilience into local community plans, using the County of Kauaʻi’s efforts as a case study. Researchers will combine broader climate science risk information with local knowledge to support statewide goals to prepare counties for future climate hazards.

Integration of next-generation sequencing into traditional Hawaiian practices to improve management and restoration of fishponds

PI: Robert Toonen
With Hawaiian fishponds as models of sustainable aquatic resource management, this study uses two important crab species, Portunus sanguinolentus hawaiiensis and Scylla serrata, to explore whether fishponds are self-seeding, importing, or exporting species, and whether traditional harvest practices continue to be viable. Early results show a broad diversity of crab sizes, with a possibility of tagging and tracking crabs outside the fishpond, as well as within.

Longitudinal assessment: Our Project in Hawaiʻi’s Intertidal (OPIHI)

PI: Kanesa Seraphin
This project revisited the Hawaiian intertidal zone, last studied over a decade ago, to document, monitor, and assess changes in species compositions due to factors like climate change, coastal development, and the spread of invasive species. The project trained and mentored undergraduate students as interns, for college credit, gaining important, required hands-on research experience. By engaging these students as well as community members in this place-based research, 48 comprehensive surveys were completed across the state, with preliminary results suggesting the spread of invasive algae and changes to water quality.
