Global to local scale simulations of streamflow in the Merced, American, and Carson Rivers, Sierra Nevada, California Global to local scale simulations of streamflow in the Merced, American, and Carson Rivers, Sierra Nevada, California
Atmospheric moisture transport and moisture budgets during winter (December-April) simulated by the National Centers for Environmental Prediction (NCEP) regional spectral model (RSM) are examined and used to simulate streamflow variations in the Sierra Nevada. The RSM was nested in 2"-latitude x 2"-longitude NCEPreanalyzed atmospheric-data fields (as a surrogate for a perfect forecast...

Health impacts of domestic coal use in China Health impacts of domestic coal use in China
Domestic coal combustion has had profound adverse effects on the health of millions of people worldwide. In China alone several hundred million people commonly burn raw coal in unvented stoves that permeate their homes with high levels of toxic metals and organic compounds. At least 3,000 people in Guizhou Province in southwest China are suffering from severe arsenic poisoning. The...

Holocene chronology for lunette dune deposition on the Southern High Plains, USA Holocene chronology for lunette dune deposition on the Southern High Plains, USA
Lunettes flank the margins of numerous ephemeral lakes that occur across the Southern High Plains of the United States. While their genesis is closely associated with the hydrology of the adjacent lake systems, the detailed inter-relationships between climate changes and geomorphological and hydrological changes upon the lake-lunette system has been hindered by an absence of reliable age...

Implications of climate change for Alaska's seabirds Implications of climate change for Alaska's seabirds
Seabirds are prominent and highly visible components of marine ecosystems that will be affected by global climate change. The Bering Sea region is particularly important to seabirds; populations there are larger and more diverse than in any similar region in North America—over 90% of seabirds breeding in the continental United States are found in this region. Seabirds, so named because...

Including long-term biological index performance in a multi-criteria Decision Support System Including long-term biological index performance in a multi-criteria Decision Support System
A Decision Support System (DSS) was developed for the reservoirs operated by the U.S. Bureau of Reclamation that incorporates biological resources in a palette of decision variables. A scoring technique was developed for the DSS to help to evaluate the long-term effects of proposed reservoir system operations on those variables. The biological component of the DSS was developed to help...

Intraspecific phylogeography of Lasmigona subviridis (Bivalvia: Unionidae): Conservation implications of range discontinuity Intraspecific phylogeography of Lasmigona subviridis (Bivalvia: Unionidae): Conservation implications of range discontinuity
A nucleotide sequence analysis of the first internal transcribed spacer region (ITS-1) between the 5.8S and 18S ribosomal DNA genes (640 bp) and cytochrome c oxidase subunit I (COI) of mitochondrial DNA (mtDNA) (576 bp) was conducted for the freshwater bivalve Lasmigona subviridis and three congeners to determine the utility of these regions in identifying phylogeographic and...

Management of groundwater supply and water quality in the Los Angeles Basin, California Management of groundwater supply and water quality in the Los Angeles Basin, California
Water use and water needs in the coastal Los Angeles Basin in California have been very closely tied to the development of the region during the last 150 years. The first water wells were drilled in the mid-1800s. Currently about 40% of the water supply (9.4 m3 s-1) in the region is provided by groundwater. Other sources of water supply include reclaimed water and surface water imported...

Micrometeorologic methods for measuring the post-application volatilization of pesticides Micrometeorologic methods for measuring the post-application volatilization of pesticides
A wide variety of micrometeorological measurement methods can be used to estimate the postapplication volatilization of pesticides from treated fields. All these estimation methods require that the entire study area have the same surficial characteristics, including the area surrounding the actual study site, and that the pesticide under investigation be applied as quickly and as...

Modeling variability in replicated surveys at aggregation sites Modeling variability in replicated surveys at aggregation sites
Surveys of aggregation sites can provide unbiased estimates of annual trends in population size if the proportion of the population counted at these sites does not vary systematically among years. However, counts at these sites tend to be highly variable and resulting trend estimates typically have poor precision. I developed an index based on a simple parametric model for counts of...
