Microbial degradation of atmospheric halocarbons
Ronald S. Oremland
2003, Book chapter, Microbiology of atmospheric trace gases
Halocarbons are present in the atmosphere at parts-per-trillion (ppt) mixing ratios and are represented by such substances as chlorofluorocarbons (CFCs), hydrochlolofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and methyl halides like methyl bromide (MeBr) and their further substituted halomethane analogues (e. g., dibromomethane, bromoform). Many Halocarbons have only an anthropogenic origin (e.g., CFCs,...

Geochemical processes controlling transport of arsenic in groundwater: A review of adsorption
Kenneth G. Stollenwerk
A. H. Welch, Kenneth G. Stollenwerk, editor(s)
2003, Book chapter, Arsenic in Ground Water
Adsorption is the predominate mechanism controlling transport of arsenic in many ground water systems. Hydrous oxides of iron, aluminum, and manganese, and clay minerals are commonly associated with aquifer solids and have been shown to be significant adsorbents of arsenic. The extent of arsenic adsorption is influenced by the chemistry...

Status assessment and conservation plan for the Western Burrowing Owl in the United States

2003, Biological Technical Publication BTP-R6001-2003
The Western Burrowing Owl (Athene cunicularia hypugaea) is a grassland specialist distributed throughout w. North America, primarily in open areas with short vegetation and bare ground in desert, grassland, and shrub-steppe environments. Burrowing Owls are dependent on the presence of fossorial mammals (primarily prairie dogs and ground squirrels), whose burrows...

Monitoring amphibians in Great Smoky Mountains National Park
C. Kenneth Dodd Jr.
2003, Circular 1258
Amphibian species have inexplicably declined or disappeared in many regions of the world, and in some instances, serious malformations have been observed. In the United States, amphibian declines frequently have occurred even in protected areas. Causes for the declines and malformations probably are varied and may not even be related....
Global carbon sequestration in tidal, saline wetland soils
G.L. Chmura, S.C. Anisfeld, Donald R. Cahoon, J.C. Lynch
2003, Global Biogeochemical Cycles (17)
Wetlands represent the largest component of the terrestrial biological carbon pool and thus play an important role in global carbon cycles. Most global carbon budgets, however, have focused on dry land ecosystems that extend over large areas and have not accounted for the many small, scattered carbon-storing ecosystems such as tidal saline wetlands. We compiled data for 154 sites in mangroves and salt marshes from...
Estimating mortality rates of adult fish from entrainment through the propellers of river towboats
S. Gutreuter, John M. Dettmers, David H. Wahl
2003, Transactions of the American Fisheries Society (132) 646-661
We developed a method to estimate mortality rates of adult fish caused by entrainment through the propellers of commercial towboats operating in river channels. The method combines trawling while following towboats (to recover a fraction of the kills) and application of a hydrodynamic model of diffusion (to estimate the fraction...
Predator exclusion methods for managing endangered shorebirds: Are two barriers better than one?
Robert K. Murphy, R. J. Greenwood, Jacob S. Ivan, Karen A. Smith
2003, Waterbirds (26) 156-159
Reproductive success of shorebirds can be improved by placement of predator exclosure fences along beaches or wire-mesh exclosure “cages” over nests. We predicted that these two types of exclosures used simultaneously might further improve reproductive success over that when cages alone are used. Field experiments were carried out...
Comparison of helicopter and ground surveys for North American elk Cervus elaphus and mule deer Odocoileus hemionus population composition
Louis C. Bender, Woodrow L. Myers, William R. Gould
2003, Wildlife Biology (9) 199-205
Both ground and helicopter surveys are commonly used to collect sex and age composition data for ungulates. Little attention has been paid, however, to whether data collected by each technique are similar. We compared helicopter and ground composition data for both elk Cervus elaphus and mule deer Odocoileus hemionus across a variety of habitats...
Genetic concepts and uncertainties in restoring fish populations and species
R.R. Reisenbichler, F.M. Utter, C.C. Krueger
2003, Book chapter, Strategies for restoring river ecosystems: Sources of variability and uncertainty in natural and managed systems
Genetic considerations can be crucially important to the success of reintroductions of lotic species. Current paradigms for conservation and population genetics provide guidance for reducing uncertainties in genetic issues and for increasing the likelihood of achieving restoration. Effective restoration is facilitated through specific goals and objectives developed from the definition that a restored or...

The human footprint in the west: a large-scale analysis of human impacts
Matthias Leu
2003, Fact Sheet 127-03
Background Humans have dramatically altered wildlands in the western United States over the past 100 years by using these lands and the resources they provide. Anthropogenic changes to the landscape, such as urban expansion and development of rural areas, influence the number and kinds of plants and wildlife that remain. In...
Left-Right Asymmetric Morphogenesis in the Xenopus Digestive System
Jennifer K. Muller, D.R. Prather, N. M. Nascone-Yoder
2003, Developmental Dynamics (228) 672-682
The morphogenetic mechanisms by which developing organs become left-right asymmetric entities are unknown. To investigate this issue, we compared the roles of the left and right sides of the Xenopus embryo during the development of anatomic asymmetries in the digestive system. Although both sides contribute equivalently to each of the...
Patterns and processes of population change in selected nearshore vertebrate predators
James L. Bodkin, Brenda E. Ballachey, T.A. Dean, Daniel Esler
2003, Report, EVOS Restoration Project 423 Final Report
Sea otters and harlequin ducks have not fully recovered from the oil spill. This project will explore links between oil exposure and the lack of population recovery, with the intent of understanding constraints to recovery of these species and the nearshore environment. In FY 02, sea otter work will include...
