Reproductive phase locking of mosquito populations in response to rainfall frequency

Creator:: Shaman, Jeffrey and Day, Jonathan F.
Abstract:: The frequency of moderate to heavy rainfall events is projected to change in response to global warming. Here we show that these hydrologic changes may have a profound effect on mosquito population dynamics and rates of mosquito-borne disease transmission. We develop a simple model, which treats the mosquito reproductive cycle...

Aquatic pesticide best management practices and relational database for the protection of NOAA trust species

Creator:: Gianou, Kelsey, Lam, Jennifer, Emanuel, Robert, Jepson, Paul, and Chan, Sam
Abstract:: Pesticides are widely used to control undesirable pests and may be applied directly to water or lands directly adjacent to water. There can be unintended consequences, however, to native, threatened, and endangered species. There is little information on the impacts of aquatic pesticides and best management practices (BMPs) to NOAA...

Timescales of large silicic magma systems : investigating the magmatic history of ignimbrite eruptions in the Altiplano-Puna Volcanic Complex of the Central Andes through U-Pb zircon dating

Creator:: Kern, Jamie M.
Abstract:: The Altiplano-Puna Volcanic Complex in the Central Andes is one of the youngest large silicic volcanic fields (LSVFs) in the world, erupting over 13,000 km³ of material during multiple supereruptions from 11 to 1 Ma. Understanding the timescales over which magma is stored in the crust prior to eruption is...

Investigating climate feedbacks across forcing magnitudes and time scales using the radiative kernel technique

Creator:: Jonko, Alexandra
Abstract:: Radiative feedbacks associated with changes in water vapor, temperature, surface albedo and clouds remain a major source of uncertainty in our understanding of climate's response to anthropogenic forcing. In this dissertation climate model data is used to investigate variations in feedbacks that result from changing CO₂ forcing and the time...

Dynamic seascapes : a quantitative framework for scaling pelagic ecology and biogeochemistry

Creator:: Kavanaugh, Maria T.
Abstract:: Understanding and modeling microbial responses and feedbacks to climate change is hampered by a lack of a framework in the pelagic environment by which to link local mechanism to large scale patterns. Where terrestrial ecology draws from landscape theory and practice to address issues of scale, the pelagic seascape concept...

Satellite observations of the inﬂuence of mesoscale ocean eddies on near-surface temperature, phytoplankton and surface stress

Creator:: Gaube, Peter
Abstract:: The influence of mesoscale ocean eddies on near-surface ocean temperature, surface stress and phytoplankton communities is investigated by collocating numerous satellite measurements along with vertical profiles of oceanic temperature and salinity to the interiors of eddies identified and tracked in altimetric sea surface height maps. The surface currents associated with...

The Spatial distribution of parks and crime in Seattle, Washington

Creator:: Weems, Candice Michelle
Abstract:: Parks help to build social cohesion within a community. Urban open spaces offer a sense of place, act as the focal points for public gatherings, and provide an opportunity for social networking (Francis, 2003; Hayward, 1989). While offering so much they are also known to be places of disgust and...

Recruitment, Growth and Mortality of an Antarctic Hexactinellid Sponge, Anoxycalyx joubini

Creator:: Dayton, Paul K., Kim, Stacy, Jarrell, Shannon C., Oliver, John S., Hammerstrom, Kamille, Fisher, Jennifer L., O'Connor, Kevin, Barber, Julie S., Robilliard, Gordon, Barry, James, Thurber, Andrew R., and Conlan, Kathy
Abstract:: Polar ecosystems are sensitive to climate forcing, and we often lack baselines to evaluate changes. Here we report a nearly 50-year study in which a sudden shift in the population dynamics of an ecologically important, structure-forming hexactinellid sponge, Anoxycalyx joubini was observed. This is the largest Antarctic sponge, with individuals...

Effects of land use policy on urban growth rates in the Willamette Valley, Oregon

Creator:: Davis, Ellen and Davis, Ellen H.
Abstract:: This study seeks to determine the correlation between changes in statewide land use planning policies and the resulting periods of high or low urban growth in the Willamette Valley, Oregon using automated classification methods and freely available satellite imagery. To protect its farms, forests and open spaces, Oregon became the...

A Bayesian approach to marine spatial planning

Creator:: Erhardt, Morgan William
Abstract:: The marine ecosystem provides a broad spectrum of services for a wide array of user groups. Such broad use of marine resources often results in use conflicts between ecosystem elements and human interests. To help mitigate these conflicts, the Bayesian Analysis for Spatial Siting (BASS) tool was developed to incorporate...
