Factors Affecting The Site Of Investment, And The Reliance On Savings For Arctic Breeders: The Capital–Income Dichotomy Revisited, Marcel Klaassen, Kenneth F. Abraham, Robert L. Jefferies, Mark Vrtiska

Nebraska Game and Parks Commission: Staff Research Publications

The extent to which migratory birds that breed in the Arctic and winter in southern biomes rely on residual body stores for reproduction is unresolved. The short arctic summer and the limited availability of food early in the season constrain the time available for successful reproduction. Birds that are able to bring sufficient endogenous reserves to the breeding ground to meet, at least partially, the demands of egg-laying can initiate clutch production soon after arrival, thereby shortening the length of the breeding season and improving the chances of reproductive success. The amount of reserves available will be influenced by body …

Ecology Of The Missouri River. Progress Report, Dingell-Johnson Project F-75-R-24, Supplement I - Missouri River Creel Survey, Camp Creek To Kansas State Line, 1 April Through 13 October 2006., Gerald Mestl

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 29 March through 10 October 2003. This is the fourth of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data. Anglers spent over 30,000 hours fishing the Missouri River from Camp Creek (rk 883.5) to the Kansas state line (rk 790.2) during the survey period. Effort peaked during the …

What Is A Population? An Empirical Evaluation Of Some Genetic Methods For Identifying The Number Of Gene Pools And Their Degree Of Connectivity, Robin Waples, Oscar Gaggiotti

United States Department of Commerce: Staff Publications

We review commonly used population definitions under both the ecological paradigm (which emphasizes demographic cohesion) and the evolutionary paradigm (which emphasizes reproductive cohesion) and find that none are truly operational. We suggest several quantitative criteria that might be used to determine when groups of individuals are different enough to be considered ‘populations’. Units for these criteria are migration rate (m) for the ecological paradigm and migrants per generation (Nm) for the evolutionary paradigm. These criteria are then evaluated by applying analytical methods to simulated genetic data for a finite island model. Under the standard parameter set …

Preserving Nature, Shahid Naeem, Robin S. Waples, Craig Moritz

United States Department of Commerce: Staff Publications

To consider the broader environmental significance of protecting species at risk of extinction, we must first consider the roles or functions that species fulfill in nature. Although "nature" has many definitions, here we define it to mean the end product of ecological and evolutionary processes. That is, within ahabitat, region, or biosphere, the condition of the soil, water, air, and biota reßects the outcome of physical, chemical, ecological, and evolutionary processes. We refer to this combination of abiotic and biotic conditions as "nature" and to the ecological and evolutionary processes that create it as "natural processes."

Using these definitions, we …

Shepherd's Beaked Whale (Tasmacetus Shepherdi): Information On Appearance And Biology Based On Strandings And At-Sea Observations, Robert L. Pitman, Anton L. Van Helden, Peter B. Best, A. Pym

United States Department of Commerce: Staff Publications

Shepherd’s beaked whale (Tasmacetus shepherdi), one of the least known cetaceans in the world (Mead 1989, 2002), is currently represented by approximately 42 stranding records and 5 unconfirmed live sightings. Most of the strandings have been from New Zealand (including the Chatham Islands—24 records), but also the Juan Fernandez Islands (2), Argentina (7), Tristan da Cunha (6), and Australia (3) (Fig. 1). A stranding reported from the South Sandwich Islands (Mead 2002) was actually a “probable” at-sea sighting near Shag Rocks (position of sighting: 53°45'S, 42°30' W) reported by Laughlin (1996, see below), and purported strandings from South Africa (e.g., …

Survival Estimates Of Western Gray Whales Eschrichtius Robustus Incorporating Individual Heterogeneity And Temporary Emigration, Amanda Bradford, Paul R. Wade, David Weller, Alexander M. Burdin, Yulia V. Ivashchenko, Grigory A. Tsidulko, Glenn R. Vanblaricom, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Gray whales Eschrichtius robustus exist as a 2 geographically and genetically distinct populations in the eastern and western North Pacific. Subjected to intensive commercial whaling during the 19th and 20th centuries, the western population presently numbers approximately 100 individuals and is regarded as one of the most endangered baleen whale populations in the world.

Spatial Statistical Models That Use Flow And Stream Distance, Jay M. Ver Hoef, Erin Peterson, David Theobald

United States Department of Commerce: Staff Publications

We develop spatial statistical models for stream networks that can estimate relationships between a response variable and other covariates, make predictions at unsampled locations, and predict an average or total for a stream or a stream segment. There have been very few attempts to develop valid spatial covariance models that incorporate flow, stream distance, or both. The application of typical spatial autocovariance functions based on Euclidean distance, such as the spherical covariance model, are not valid when using stream distance. In this paper we develop a large class of valid models that incorporate flow and stream distance by using spatial …

Cetacean Abundance In Hawaiian Waters Estimated From A Summer/Fall Survey In 2002, Jay Barlow

United States Department of Commerce: Staff Publications

Cetacean abundance is estimated for the U.S. Exclusive Economic Zone (EEZ) around the Hawaiian Islands based on a ship line-transect survey from August to November, 2002. Sighting detection functions are estimated from this and other NOAA research surveys from 1986 to 2002 using a new, multiple-covariate approach. Twenty-four species were seen on this survey, including two species (Fraser’s dolphin [Lagenodelphis hosei] and sei whale [Balaenoptera borealis]) that had not been previously documented to occur in Hawaiian waters. The most abundant large whales are sperm whales (Physeter macrocephalus) and Bryde’s whales (Balaenoptera edeni). The most …

United States Air Force Posture Statement 2006, U.S. Air Force

United States Air Force: Publications

Over a century ago, America crossed the threshold of powered flight and gave wings to the world. Soon military leaders realized the implications of this development, and warfare was changed forever. America was fortunate to have "Great Captains" with the vision to imagine the possibilities of air and space power - Airmen like Billy Mitchell, Frank Andrews, Hap Arnold, Ira Eaker, Jimmy Doolittle, Bennie Schriever. They have given us a proud heritage of courage, excellence and innovation. In so doing, they also give us a sense of perspective and a way to understand the Air Force's future.

Development Of A Reference Dose For The Persistent Congeners Of Weathered Toxaphene Based On In Vivo And In Vitro Effects Related To Tumor Promotion, Ted Simon, Randall Manning

United States Environmental Protection Agency: Publications

Toxaphene is a mixture of chlorinated camphenes and bornanes that was produced and used in the United States until 1982. 1.3 million tons of toxaphene have been released worldwide. ‘‘Technical’’ toxaphene (TT) consists of a mixture of up to 800 different chemicals, known as congeners. TT weathers in the environment by both biotic and abiotic processes. The human body burden of toxaphene consists of only five persistent congeners that are not metabolized; three of these occur in considerably greater amounts than the other two. Because of the rapid metabolism and excretion of the non-persistent congeners, the persistent congeners that make …

Microbial Reduction Of Fe(Iii) In The Fithian And Muloorina Illites: Contrasting Extents And Rates Of Bioreduction, Jennifer L. Seabaugh, Hailiang Dong, Ravi K. Kukkadapu, Dennis D. Eberl, John P. Morton, Jinwook Kim

United States Department of Energy: Publications

Shewanella putrefaciens CN32 reduces Fe(III) within two illites which have different properties: the Fithian bulk fraction and the <0.2 mm fraction of Muloorina. The Fithian illite contained 4.6% (w/w) total Fe, 81% of which was Fe(III). It was dominated by illite with some jarosite (~32% of the total Fe(III)) and goethite (11% of the total Fe(III)). The Muloorina illite was pure and contained 9.2% Fe, 93% of which was Fe(III). Illite suspensions were buffered at pH 7 and were inoculated with CN32 cells with lactate as the electron donor. Select treatments included anthraquinone-2,6-disulfonate (AQDS) as an electron shuttle. Bioproduction of Fe(II) was determined by ferrozine analysis. The unreduced and bioreduced solids were characterized by Mossbauer spectroscopy, X-ray diffraction and transmission electron microscopy. The extent of Fe(III) reduction in the bulk Fithian illite was enhanced by the presence of AQDS (73%) with complete reduction of jarosite and goethite and partial reduction of illite. Mossbauer spectroscopy and chemical extraction determined that 21ÿ25% of illite-associated Fe(III) was bioreduced. The extent of bioreduction was less in the absence of AQDS (63%) and only jarosite was completely reduced with partial reduction of goethite and illite. The XRD and TEM data revealed no significant illite dissolution or biogenic minerals, suggesting that illite was reduced in the solid state and biogenic Fe(II) from jarosite and goethite was either released to aqueous solution or adsorbed onto residual solid surfaces. In contrast, only 1% of the structural Fe(III) in Muloorina illite was bioreduced. The difference in the extent and rate of bioreduction between the two illites was probably due to the difference in layer charge and the total structural Fe content between the Fithian illite (0.56 per formula) and Muloorina illite (0.87). There may be other factors contributing to the observed differences, such as expandability, surface area and the arrangements of Fe in the octahedral sheets. The results of this study have important implications for predicting microbe-induced physical and chemical changes of clay minerals in soils and sediments.

Adsorption Of Uranyl On Gibbsite: A Time-Resolved Laser-Induced Fluorescence Spectroscopy Study, Hyun-Shik Chang, Gregory Korshin, Zheming Wang, John M. Zachara

United States Department of Energy: Publications

Uranyl adsorbed on gibbsite at pH 4.0-8.0 and ionic strengths (ISs) 0.001-0.4 M (NaClO₄) in the absence of carbonate was studied using time-resolved laser-induced fluorescence spectroscopy (TRLIFS) under cryogenic conditions. TRLIFS data showed the presence of several distinct emission components. Their contributions were determined using the evolving factor analysis approach. Four components denoted as species A, B, C, and D were discerned. Each of them was characterized by a characteristic response to pH and IS changes and also by a unique combination of the values of the fundamental transition energyE_0,0, vibronic spacing ∆E, and half-width …

C-Type Cytochrome-Dependent Formation Of U(Iv) Nanoparticles By Shewanella Oneidensis, Matthew J. Marshall, Alexander Beliaev, Alice Dohnalkova, David Kennedy, Liang Shi, Zheming Wang, Maxim Boyanov, Barry Lai, Kenneth M. Kemner, Jeffrey Mclean, Samantha Reed, David Culley, Vanessa L. Bailey, Cody Simonson, Daad A. Saffarini, Margaret Romine, John M. Zachara, James K. Fredrickson

United States Department of Energy: Publications

Modern approaches for bioremediation of radionuclide contaminated environments are based on the ability of microorganisms to effectively catalyze changes in the oxidation states of metals that in turn influence their solubility. Although microbial metal reduction has been identified as an effective means for immobilizing highly-soluble uranium(VI) complexes in situ, the biomolecular mechanisms of U(VI) reduction are not well understood. Here, we show that c-type cytochromes of a dissimilatory metal-reducing bacterium, Shewanella oneidensis MR-1, are essential for the reduction of U(VI) and formation of extracelluar UO₂ nanoparticles. In particular, the outer membrane (OM) decaheme cytochrome MtrC (metal reduction), previously implicated …

A Health Risk Evaluation For Pallid Sturgeon (Scaphirhynchus Albus) In The Lower Platte River Using Shovelnose Sturgeon (Scaphirhynchus Platorynchus) As A Surrogate, Matthew S. Schwarz, Christina D. Lydick, Donald E. Tillit, Diana M. Papoulias, Timothy S. Gross

United States Fish and Wildlife Service: Publications

Most sturgeon species worldwide have been in steep decline since the 1900s. This research evaluated shovelnose sturgeon health, reproduction, and exposure to environmental contamination in the lower Platte River. Shovelnose sturgeon served as a surrogate species for the endangered pallid sturgeon and their health was assessed by incorporating measurements of general health with hepatic, immune, and reproductive system biomarkers. Environmental contaminants were measured in water, potential pallid sturgeon food items (cyprinid minnows), and shovelnose sturgeon digesta, liver, and blood plasma. Contaminants detected in shovelnose sturgeon at concentrations of concern included PCBs, selenium, and atrazine. Total PCBs in carcasses (n = …

Adaptive Harvest Management: 2006 Hunting Season

United States Fish and Wildlife Service: Publications

The process of setting waterfowl hunting regulations is conducted annually in the United States (Blohm 1989). This process involves a number of meetings where the status of waterfowl is reviewed by the agencies responsible for setting hunting regulations. In addition, the U.S. Fish and Wildlife Service (USFWS) publishes proposed regulations in the Federal Register to allow public comment. This document is part of a series of reports intended to support development of harvest regulations for the 2006 hunting season. Specifically, this report is intended to provide waterfowl managers and the public with information about the use of adaptive harvest management …

American Woodcock Population Status, 2006, James R. Kelley Jr., Rebecca D. Rau

United States Fish and Wildlife Service: Publications

Singing-ground Survey data indicated that the numbers of displaying American woodcock (Scolopax minor) in the Eastern Region in 2006 was unchanged from 2005; however, the Central Region experienced an 8% decline. There was no significant trend in woodcock heard in either the Eastern or Central Region during 1996-06. This represents the third consecutive year since 1992 that the 10-year trend estimate did not indicate a significant decline. There were longterm (1968-06) declines of 1.9% per year in the Eastern Region and 1.8% per year in the Central Region. The 2005 recruitment index for the U.S. portion of the …

Intercontinental Biotic Invasions: What Can We Learn From Native Populations And Habitats?, Qinfeng Guo

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The effectiveness of management strategies for invasive species is often hampered by a lack of clear understanding of the factors that limit species distributions. The distribution of exotic species, especially those that are invasive, are often so dynamic that limiting factors are difficult to identify. Comparisons of exotic species between their native ranges, where they are presumably close to equilibrium with controlling factors, and their ranges in areas of introduction can circumvent this difficulty. Such studies would help identify (1) limiting factors for distributions in native ranges, (2) factors associated with a high degree of invasiveness, (3) changes in genetics …

Fat Dynamics Of Arctic-Nesting Sandpipers During Spring In Mid-Continental North America, Gary Krapu, Jan Eldridge, Cherri Grato-Trevor, Deborah Buhl

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We measured fresh body mass, total body fat, and fat-free dry mass (FFDM) of three species of Arctic-nesting calidrid sandpipers (Baird’s Sandpiper [Calidris bairdii], hereafter “BASA”; Semipalmated Sandpiper [C. pusilla], hereafter “SESA”; and White-rumped Sandpiper [C. fuscicollis], hereafter “WRSA”) during spring stopovers in the Prairie Pothole Region (PPR) of North Dakota, and evaluated the contribution of stored fat to (1) energy requirements for migration to their Arctic-breeding grounds and (2) nutrient needs for reproduction. All spring migrant WRSA (n = 124) and BASA (n = 111), and all but 2 of 99 SESA we …

A Preliminary Biological Assessment Of Long Lake National Wildlife Refuge Complex, North Dakota, Murray K. Laubhan, Robert A. Gleason, Gregory A. Knutsen, Rachel A. Laubhan, N. H. Euliss Jr.

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

This report represents an initial biological assessment of wetland conditions on Long Lake National Wildlife Refuge (NWR), Slade NWR, and Florence Lake NWR that was conducted as part of the pre-planning phase for development of a Comprehensive Conservation Plan (CCP). According to the 1997 National Wildlife Refuge System Improvement Act (NWRSIA), decisions guiding NWR management should be based on the best available scientific information. Therefore, this report attempts to integrate relevant information from many different scientific disciplines (e.g., geology, hydrology, biology) to assist the U.S. Fish and Wildlife Service (USFWS) in identifying ecological constraints and opportunities imposed by the land …

Oxygen Exposure Promotes Fuel Diversity For Shewanella Oneidensis Microbial Fuel Cells, Justin C. Biffinger, Jacqueline N. Byrd, Breanna L. Dudley, Bradley R. Ringeisen

United States Navy: Publications

Miniature microbial fuel cells (mini-MFCs) were used to monitor the current generated by Shewanella oneidensis DSP10 under both anaerobic and aerobic conditions when exposed to glucose as a potential electron donor. In addition to glucose, other carbon fuels including fructose, sucrose, acetate, and ascorbic acid were also tested. When the anolyte containing S. oneidensis was grown in the presence of oxygen, power densities of 270±10, 350±20, and 120±10 W/m³ were recorded from the mini-MFC for glucose, fructose, and ascorbic acid electron donors, respectively, while sucrose and acetate produced no response. The power produced from glucose decreased considerably (≤100 W/m …

High Power Density From A Miniature Microbial Fuel Cell Using Shewanella Oneidensis Dsp10, Bradley R. Ringeisen, Emily Henderson, Peter K. Wu, Jeremy Pietron, Ricky Ray, Brenda J. Little, Justin C. Biffinger, Joanne M. Jones-Meehan

United States Navy: Publications

A miniature microbial fuel cell (mini-MFC) is described that demonstrates high output power per device crosssection (2.0 cm²) and volume (1.2 cm³). Shewanella oneidensis DSP10 in growth medium with lactate and buffered ferricyanide solutions were used as the anolyte and catholyte, respectively. Maximum power densities of 24 and 10 mW/m² were measured using the true surface areas of reticulated vitreous carbon (RVC) and graphite felt (GF) electrodes without the addition of exogenous mediators in the anolyte. Current densities at maximum power were measured as 44 and 20 mA/m² for RVC and GF, while short …

United States Navy: Publications

We surveyed adults in a randomly selected sample of 1,000 households in 50 villages in nine malarial sub-districts in Purworejo, central Java, Indonesia from May to July 2001. The survey assessed malaria knowledge, attitudes, and practices in communities experiencing epidemic malaria to begin exploring broad strategies for controlling the disease in the region. A pre-tested survey instrument consisting of 93 questions addressed demographic characteristics, socioeconomic factors, knowledge and perceptions of malaria, burden and severity of disease, treatment-seeking behavior, malaria prevention practices, and perceptions of government malaria control efforts. The survey was taken by in-person interview of all subjects. Most (97%) …

Divergent Patterns Of Abundance And Age-Class Structure Of Headwater Stream Tadpoles In Burned And Unburned Watersheds, Blake R. Hossack, Paul Stephen Corn, Daniel B. Fagre

United States Geological Survey: Staff Publications

Wildfire is a potential threat to many species with narrow environmental tolerances like the Rocky Mountain tailed frog (Ascaphlls montanlls Mittleman and Myers, 1949), which inhabits a region where the frequency and intensity of wildfires are expected to increase. We compared pre- and post-fire counts of tadpoles in eight streams in northwestem Montana to determine the effects of wildfire on A. montanus. All streams were initially sampled in 2001, 2 years before four of them bumed in a large wildfire, and were resampled during the 2 years follo\ving the fire. Counts of tadpoles were similar in the 1\\'0 …

Expression Of A Novel Marine Viral Single-Chain Serine Palmitoyltransferase And Construction Of Yeast And Mammalian Single-Chain Chimera, Gongshe Han, Kennerth Gable, Lianying Yan, Michael J. Allen, William H. Wilson, Prasun Moitra, Jeffrey M. Harmon, Teresa M. Dunn

Uniformed Services University of the Health Sciences

The genus Coccolithovirus is a recently discovered group of viruses that infect the globally important marine calcifying microalga Emiliania huxleyi. Surprisingly, the viral genome contains a cluster of putative sphingolipid biosynthetic genes not found in other viral genus. To address the role of these genes in viral pathogenesis, the ehv050 gene predicted to encode a serine palmitoyltransferase (SPT), the first and rate-limiting enzyme of sphingolipid biosynthesis, was expressed and characterized in Saccharomyces cerevisiae. We show that the encoded protein is indeed a fully functional, endoplasmic reticulum-localized, single-chain SPT. In eukaryotes SPT is a heterodimer comprised of long chain …

Members Of The Arabidopsis Fae1-Like 3-Ketoacyl-Coa Synthase Gene Family Substitute For The Elop Proteins Of Saccharomyces Cerevisiae, Shilpi Paul, Kenneth Gable, Frédéric Beaudoin, Edgar Cahoon, Jan Jaworski, Johnathan A. Napier, Teresa M. Dunn

Uniformed Services University of the Health Sciences

Several 3-keto-synthases have been studied, including the soluble fatty acid synthases, those involved in polyketide synthesis, and the FAE1-like 3-ketoacyl-CoA synthases. All of these condensing enzymes have a common ancestor and an enzymatic mechanism that involves a catalytic triad consisting of Cys, His, and His/Asn. In contrast to the FAE1-like family of enzymes that mediate plant microsomal fatty acid elongation, the condensation step of elongation in animals and in fungi appears to be mediated by the Elop homologs. Curiously these proteins bear no resemblance to the well characterized 3-keto-synthases. There are three ELO genes in yeast that encode the homologous …
