Transmission of avian malaria in the Hawaiian Islands varies across altitudinal gradients and is greatest at elevations below 1500 m where both temperature and moisture are favorable for the sole mosquito vector, Culex quinquefasciatus, and extrinsic sporogonic development of the parasite, Plasmodium relictum. Potential consequences of global warming on this system have been recognized for over a decade with concerns that increases in mean temperatures could lead to expansion of malaria into habitats where cool temperatures currently limit transmission to highly susceptible endemic forest birds. Recent declines in two endangered species on the island of Kaua’i, the ‘Akikiki (Oreomystis bairdi) and ‘Akeke’e (Loxops...

Climate change is anticipated to affect freshwater resources, but baseline data on the functioning of tropical watersheds is lacking, limiting efforts that seek to predict how watershed processes, water supply, and streamflow respond to anticipated changes in climate and vegetation change, and to management. To address this data gap, we applied the distributed hydrology soil vegetation model (DHSVM) across 88 watersheds spanning a highly constrained, 4500 mm mean annual rainfall (MAR) gradient on Hawai‘i Island to quantify stream flow at 3-h time-steps for eight years in response to the independent and interactive effects of (1) large observed decrease in MAR; (2) projected warming and altered precipitation; and...

Since the beginning of the industrial revolution, the concentration of atmospheric CO2 has been rising due to the burning of fossil fuels. increased absorption of this CO2 by the oceans is lowering the seawater pH and aragonite saturation state (Ωar). This process is known as ocean acidification (OA). numerous studies have shown a direct correlation between declining ocean pH, declining Ωar, and declining coral growth, but the mechanism is not understood. Various experiments designed to evaluate the relative importance of pH, CO3 2–, Ωar, HCO3 –, aqueous CO2, total alkalinity, and total inorganic carbon (Ct) to coral calcification have led to opposing conclusions. A reanalysis of existing data suggests that the...

One of the greatest ecological, social and economic issues of the day is the problem of climate change. Increasing levels of carbon dioxide (CO2) in the atmosphere are increasing global temperatures. Much of the CO2 dissolves in the ocean, creating more acidic conditions and leading to a process known as ocean acidification (OA). Higher temperatures and increased levels of CO2 operating independently are known to be detrimental to corals, but little is known about their effect when operating in unison. Irradiance has a great influence on coral calcification rates and can interact with higher temperature and increased OA to an unknown extent. Therefore, experiments were performed in continuous flow mesocosms under...

A landscape-based assessment of climate change vulnerability for native Hawaiian plants Final report
A landscape-based assessment of climate change vulnerability for native Hawaiian plants Final report
We analyzed the chemical composition of wood produced by Māmane, a tropical tree growing in Hawai’i, in order to reconstruct changes in climate over the Hawaiian Islands. Specifically, we measured changes in the relative abundance of carbon and oxygen isotopes taken up by the trees during photosynthesis at high elevation sites on Mauna Kea. We found that these isotopes reflect the climatic conditions (precipitation and temperature) under which the trees lived, allowing us to reconstruct relative changes in climate extending back ~130 years. Our results indicate decadal-scale changes in precipitation that correlate well with large-scale atmospheric and ocean circulation patterns that dominate much of the Pacific....

Determination of carbon isotope (δ13C) values of tree-ring tissue is a well-established method to reconstruct past climate variability at annual resolution, but such records are limited in tropical latitudes due to the lack of well-defined annual growth bands. Recent work has demonstrated the potential for high-resolution, intra-ring δ13C records to help define ring boundaries in tropical environments and provide additional climate information at sub-annual resolution. Here we present a high-resolution, intra-ring carbon isotope (δ13C) record of the Hawaiian endemic species Sophora chrysophylla(also known as “māmane”) in order to assess the ability to extract seasonal climate information from these drought tolerant...

In the tropics, ample freshwater is the primary resource supporting thriving human and ecological communities. In the Pacific Islands, many watersheds are threatened by climate change, urban encroachment, and invasion by water-demanding exotic plant species like strawberry guava (SG). To maintain an adequate freshwater supply, adaptive management strategies are needed to address these concerns while confronting operational barriers to implementation. We developed a prototype watershed decision support tool (WDST) that incorporated: (i) distributed hydrology modeling to quantify effects of climate change and SG invasion on freshwater yield; (ii) a decision support tool that linked potential changes in yield with...
