A Brochure describing the Climate Change and Invasive Species Impacts on Watersheds WDST
Although climate change is predicted to place mountain-top and other narrowly endemic species at severe risk of extinction, the ecological processes involved in such extinctions are still poorly resolved. In addition, much of this biodiversity loss will likely go unobserved, and therefore largely unappreciated. The Haleakalā silversword is restricted to a single volcano summit in Hawai‘i, but is a highly charismatic giant rosette plant that is viewed by 1–2 million visitors annually. We link detailed local climate data to a lengthy demographic record, and combine both with a population-wide assessment of recent plant mortality and recruitment, to show that after decades of strong recovery following successful management,...
The “Assessment and Inventory of Ecosystem Services and Environmental Threats” research project will deliver an inventory of existing ecosystem services assessments, products, and decision-support or visualization tools conducted within the Appalachian LCC boundary. The inventory will document and assess the classification, methodology used, describe priority ecosystem services and how they were identified, and provide economic valuations if available. Research will also involve a regional survey and workshops within our boundary to assemble a list of high priority economic goods and services and non‐monetized values and benefits that are dependent on Appalachia’s natural assets while identifying the associated...
Increased water levels, erosion, salinity, and flooding associated with sea-level rise threaten coastal and wetland habitats of endangered waterbirds, sea turtles, monk seals, and migratory shorebirds. As sea-level rises the greatest challenge will be prioritizing management actions in response to impacts. We provide decision makers with two solutions to adaptively manage the impacts of SLR and apply these methods to three coastal wetland environments at Keālia National Wildlife Refuge (south Maui), Kanaha State Wildlife Sanctuary (north Maui), and James Campbell National Wildlife Refuge (north O‘ahu). Firstly, due to the low gradient of most coastal plain environments, the rate of SLR impact will rapidly accelerate...
This final report summarizes the project’s major accomplishments in research, training and product development. We have accomplished our primary goals of this project. With our research we contribute significant new information to the monitoring and assessment of ongoing climatic changes in Hawai‘i. Over the last decades the general trends in the wet season rainfall was negative and given the modeled climate scenarios from CMIP3 and CMIP5, it is very likely these trends are going to continue in the 21st century. In this research project, we improved the spatial information content of our statistical downscaling method through the introduction of the Rainfall Atlas of Hawai‘i station data sets and the use of improved...
Point Blue Final Report Climate Change Monitoring Workshop Summary and Report
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...
Future Distribution of Cloud Forests and Associated Species in Hawaii Final Report
Forested Stream and/or Seepage Forested stream environments are typically found in the buffer zones between forested land and stream banks, often known as riparian zones. Stream headwaters and seepage areas occur where ground water percolates to the surface through muck, mossy rock, and nettles. It can also be found under rocks, among gravel, or cobble where water has begun to percolate in areas near open water. Breeding grounds are commonly found beneath mosses growing on rocks, on logs, or soil surfaces in these types of seepage areas.Predicted climate change will largely impact changes in temperature and moisture availability in forested streamand/or seepage systems, likely having a cascading effect on a species...
Hawaiian forest birds serve as an ideal group to explore the extent of climate change impacts on at-risk species. Avian malaria constrains many remaining Hawaiian forest bird species to high elevations where temperatures are too cool for malaria’s life cycle and its principal mosquito vector. The impact of climate change on Hawaiian forest birds has been a recent focus of Hawaiian conservation biology, and has centered on the links between climate and avian malaria. To elucidate the differential impacts of projected climate shifts on species with known varying niches, disease resistance and tolerance, we use a comprehensive database of species sightings, regional climate projections and ensemble distribution models...
Publication titled “​Statistical downscaling of rainfall changes in Hawai‘i based on the CMIP5 global model projections”
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...
