Defining ecosystem-based management boundaries using genetics and fisheries data

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Robert Toonen Graduate Trainee: Johanna Wren In this study, we compile and assess existing population data for marine species throughout the Hawaiian archipelago and test whether these data reveal distinct populations among sites within the ...

Disease outbreak investigation on the reefs of Kauaʻi

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Greta Aeby Co-INVESTIGATORS: Sean Callahan Graduate Trainee: Christina Runyon Outbreaks of coral disease can kill large numbers of corals and are occurring more frequently on the reefs of Hawaiʻi. In 2012, an Eyes of the Reef ...

Forecasting climate change impacts on coastal ecosystem services in Hawaiʻi through integration of ecological and social participatory models

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Christopher Lepczyk Co-INVESTIGATORS: Steven Gray Graduate Trainee: Hla Htun Both climate and land use/cover changes are expected to have significant impacts on freshwater ecosystem services and human well-being. Understanding and modeling these impacts in a manner ...

Global and regional vulnerability to 21st century climate shifts in current areas of plant growth

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Camilo Mora Graduate Trainee: Alessandra Shea Terrestrial plant production is a fundamental component of the carbon cycle on Earth, which delivers numerous ecological, economic, social and aesthetic goods and services to humanity. A growing body ...

Groundwater inundation: Doubling community damage from sea level rise

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Chip Fletcher Graduate Trainee: Shellie Habel Many of the Nation’s largest cities face risk of sea level rise induced flooding owing to their limited elevations and proximities to the coastline. Climate scientists generally agree that ...

Groundwater-derived nutrient uptake in coastal ecosystems as driver of reef accretion-erosion balance

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Megan Donahue Co-INVESTIGATORS: Henrietta Dulai, Florence Thomas Graduate Trainee: Catherine Lubarsky Coastal coral reefs are subject to freshwater impacts from many sources, including runoff from rivers and streams and discharge of groundwater into the coastal ocean ...

Groundwater-derived nutrient uptake in coastal ecosystems as driver of reef accretion-erosion balance

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Henrietta Dulai Co-INVESTIGATORS: Peter Fuleky Graduate Trainee: Christina Richardson The last century of human activity has dramatically affected coral reefs. Global changes, due to increased atmospheric carbon dioxide, and local changes, like coastal development and overfishing, ...

Groundwater-derived nutrient uptake in coastal ecosystems as driver of reef accretion-erosion balance

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Florence Thomas Co-INVESTIGATORS: Henrietta Dulai, Megan Donahue Graduate Trainee: Florybeth LaValle For coral reefs to persist grown of the reef must exceed the erosion of the reef due to chemical and biological erosion. Inputs of nutrients ...

Humankind’s biogeochemical experiment: Ocean acidification and “coral reef” dissolution

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Michael Guidry Co-INVESTIGATORS: Eric DeCarlo, Fred Mackenzie Graduate Trainee: Robert Thompson Ocean acidification (the process by which the surface waters of the ocean are becoming more acidic due to absorbing atmospheric carbon dioxide generated, in part, ...

Maintaining healthy coastal ecosystems: Understanding disease risk of Hawaiʻi’s coral reefs and sources of coral pathogens

 Research Projects 2014-2016
PRINCIPAL INVESTIGATOR: Sean Callahan Co-INVESTIGATORS: Greta Aeby Graduate Trainee: Amanda Shore Disease is an emerging problem to coral reef ecosystems worldwide. Yet, the basic mechanisms of disease in corals are poorly understood. For infectious diseases, vectors allow the ...
