Winter Feeding Sites Of Hay In Round Bales As Major Developmental Sites Of Stomoxys Calcitrans (Diptera: Muscidae) In Pastures In Spring And Summer, Alberto B. Broce, Jerome Hogsette, Steven Paisley Jan 2005

Winter Feeding Sites Of Hay In Round Bales As Major Developmental Sites Of Stomoxys Calcitrans (Diptera: Muscidae) In Pastures In Spring And Summer, Alberto B. Broce, Jerome Hogsette, Steven Paisley

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The stable fly, Stomoxys calcitrans (L.), historically has been a pest of livestock in confined operations but seldom of animals on pastures or rangelands. In the past two decades, however, S. calcitrans has become a major pest of cattle and horses on pastures in the midwestern United States. Although there usually is an overabundance of diverse stable fly and house fly, Musca domestica L., larval habitats in confined livestock operations, no larval habitat for stable flies has been clearly identified in the pasture-range environment. Because the winter feeding of hay in round bales results in significant amounts of hay wastage …

Comparison Of A Novel Passive Sampler To Standard Water-Column Sampling For Organic Contaminants Associated With Wastewater Effluents Entering A New Jersey Stream, D. A. Alvarez, P. E. Stackelberg, J. D. Petty, J. N. Huckins, E. T. Furlong, S. D. Zaugg, M. T. Meyer

United States Geological Survey: Staff Publications

Four water samples collected using standard depth and width water-column sampling methodology were compared to an innovative passive, in situ, sampler (the polar organic chemical integrative sampler or POCIS) for the detection of 96 organic wastewater-related contaminants (OWCs) in a stream that receives agricultural, municipal, and industrial wastewaters. Thirty-two OWCs were identified in POCIS extracts whereas 9–24 were identified in individual water-column samples demonstrating the utility of POCIS for identifying contaminants whose occurrence are transient or whose concentrations are below routine analytical detection limits. Overall, 10 OWCs were identified exclusively in the POCIS extracts and only six solely identified in …

Characterization Of Waste Rock Associated With Acid Drainage At The Penn Mine, California, By Ground-Based Visible To Short-Wave Infrared Reflectance Spectroscopy Assisted By Digital Mapping, Irene C. Montero S., George H. Brimhall, Charles N. Alpers, Gregg A. Swayze Jan 2005

Characterization Of Waste Rock Associated With Acid Drainage At The Penn Mine, California, By Ground-Based Visible To Short-Wave Infrared Reflectance Spectroscopy Assisted By Digital Mapping, Irene C. Montero S., George H. Brimhall, Charles N. Alpers, Gregg A. Swayze

United States Geological Survey: Staff Publications

Prior to remediation at the abandoned Cu–Zn Penn Mine in the Foothills massive sulfide belt of the Sierra Nevada, CA, acid mine drainage (AMD) was created, in part, by the subaerial oxidation of sulfides exposed on several waste piles. To support remediation efforts, a mineralogical study of the waste piles was undertaken by acquiring reflectance spectra (measured in the visible to short-wave infrared range of light (0.35–2.5 Am) using a portable, digitally integrated pen tablet PC mapping system with differential global positioning system and laser rangefinder support. Analysis of the spectral data made use of a continuum removal and band-shape …

A Curious Pellet From A Great Horned Owl (Bubo Virginianus), Neal Woodman, Carla J. Dove, Suzanne C. Peurach Jan 2005

A Curious Pellet From A Great Horned Owl (Bubo Virginianus), Neal Woodman, Carla J. Dove, Suzanne C. Peurach

United States Geological Survey: Staff Publications

One of the traditional methods of determining the dietary preferences of owls relies upon the identification of bony remains of prey contained in regurgitated pellets. Discovery of a pellet containing a large, complete primary feather from an adult, male Ring-necked Pheasant (Phasianus colchicus) prompted us to examine in detail a small sample of pellets from a Great Horned Owl (Bubo virginianus). Our analyses of feather and hair remains in these pellets documented the presence of three species of birds and two species of mammals, whereas bones in the pellets represented only mammals. This finding indicates an …

Survival And Selection Of Migrating Salmon From Capture-Recapture Models With Individual Traits, Richard W. Zabel, Tyler Wagner, James L. Congleton, Steven G. Smith, John G. Williams Jan 2005

Survival And Selection Of Migrating Salmon From Capture-Recapture Models With Individual Traits, Richard W. Zabel, Tyler Wagner, James L. Congleton, Steven G. Smith, John G. Williams

United States Geological Survey: Staff Publications

Capture–recapture studies are powerful tools for studying animal population dynamics, providing information on population abundance, survival rates, population growth rates, and selection for phenotypic traits. In these studies, the probability of observing a tagged individual reflects both the probability of the individual surviving to the time of recapture and the probability of recapturing an animal, given that it is alive. If both of these probabilities are related to the same phenotypic trait, it can be difficult to distinguish effects on survival probabilities from effects on recapture probabilities. However, when animals are individually tagged and have multiple opportunities for recapture, we …

High Dispersal In A Frog Species Suggest That It Is Vulnerable To Habitat Fragmentation, W. Chris Funk, Allison E. Greene, Paul Stephen Corn, Fred W. Allendorf Jan 2005

High Dispersal In A Frog Species Suggest That It Is Vulnerable To Habitat Fragmentation, W. Chris Funk, Allison E. Greene, Paul Stephen Corn, Fred W. Allendorf

United States Geological Survey: Staff Publications

Global losses of amphibian populations are a major conservation concern and have generated substantial debate over their causes. Habitat fragmentation is considered one important cause of amphibian decline. However, if fragmentation is to be invoked as a mechanism of amphibian decline, it must first be established that dispersal is prevalent among contiguous amphibian populations using formal movement estimators. In contrast, if dispersal is naturally low in amphibians, fragmentation can be disregarded as a cause of amphibian declines and conservation efforts can be focused elsewhere. We examined dispersal rates in Columbia spotted frogs (Rana luteiventris) using capture– recapture analysis …

Population Structure Of Columbia Spotted Frogs (Rana Luteiventris) Is Strongly Affected By The Landscape, W. Chris Funk, Michael S. Blouin, Paul Stephen Corn, Bryce A. Maxell, David S. Pilliod, Stephen Amish, Fred W. Allendorf Jan 2005

Population Structure Of Columbia Spotted Frogs (Rana Luteiventris) Is Strongly Affected By The Landscape, W. Chris Funk, Michael S. Blouin, Paul Stephen Corn, Bryce A. Maxell, David S. Pilliod, Stephen Amish, Fred W. Allendorf

United States Geological Survey: Staff Publications

Landscape features such as mountains, rivers, and ecological gradients may strongly affect patterns of dispersal and gene flow among populations and thereby shape population dynamics and evolutionary trajectories. The landscape may have a particularly strong effect on patterns of dispersal and gene flow in amphibians because amphibians are thought to have poor dispersal abilities. We examined genetic variation at six microsatellite loci in Columbia spotted frogs (Rana luteiventris) from 28 breeding ponds in western Montana and Idaho, USA, in order to investigate the effects of landscape structure on patterns of gene flow. We were particularly interested in addressing …

Conflicting Patterns Of Genetic Structure Produced By Nuclear And Mitochondrial Markers In The Oregon Slender Salamander (Batrachoseps Wrighti): Implications For Conservation Efforts And Species Management, Mark P. Miller, Susan M. Haig, Steven Wagner Jan 2005

Conflicting Patterns Of Genetic Structure Produced By Nuclear And Mitochondrial Markers In The Oregon Slender Salamander (Batrachoseps Wrighti): Implications For Conservation Efforts And Species Management, Mark P. Miller, Susan M. Haig, Steven Wagner

United States Geological Survey: Staff Publications

Endemic to Oregon in the northwestern US, the Oregon slender salamander (Batrachoseps wrighti = B. wrightorum) is a terrestrial plethodontid found associated with late successional mesic forests. Consequently, forest management practices such as timber harvesting may impact their persistence. Therefore, to infer possible future effects of these practices on population structure and differentiation, we used mitochondrial DNA sequences (cytochrome b) and RAPD markers to analyze 22 populations across their range. Phylogenetic analyses of sequence data (774 bp) revealed two historical lineages corresponding to northern and southern-distributed populations. Relationships among haplotypes and haplotype diversity within lineages suggested that the …

Geographic Variation, Genetic Structure, And Conservation Unit Designation In The Larch Mountain Salamander (Plethodon Larselli), R. Steven Wagner, Mark P. Miller, Charles M. Crisafulli, Susan M. Haig Jan 2005

Geographic Variation, Genetic Structure, And Conservation Unit Designation In The Larch Mountain Salamander (Plethodon Larselli), R. Steven Wagner, Mark P. Miller, Charles M. Crisafulli, Susan M. Haig

United States Geological Survey: Staff Publications

The Larch Mountain salamander (Plethodon larselli Burns, 1954) is an endemic species in the Pacific northwestern United States facing threats related to habitat destruction. To facilitate development of conservation strategies, we used DNA sequences and RAPDs (random amplified polymorphic DNA) to examine differences among populations of this species. Phylogenetic analyses of cytochrome b revealed a clade of haplotypes from populations north of the Columbia River derived from a clade containing haplotypes from the river’s southwestern region. Haplotypes from southeastern populations formed a separate clade. Nucleotide diversity was reduced in northern populations relative to southern populations. These results were corroborated …

Selection Of Arboreal Termitaria For Nesting By Cooperatively Breeding Micronesian Kingfishers Todiramphus Cinnamominus Reichenbachii, Dylan C. Kesler, Susan M. Haig Jan 2005

Selection Of Arboreal Termitaria For Nesting By Cooperatively Breeding Micronesian Kingfishers Todiramphus Cinnamominus Reichenbachii, Dylan C. Kesler, Susan M. Haig

United States Geological Survey: Staff Publications

Limited nest-site availability appears to be an important factor in the evolution of delayed dispersal and cooperative breeding in some cavity-nesting species. The cooperatively breeding Pohnpei subspecies of Micronesian Kingfisher Todiramphus cinnamominus reichenbachii excavates nest cavities from the nests of arboreal termites Nasutitermes spp., or termitaria. In this first published description of nest-sites for this subspecies, we used surveys, remote sensing and radiotelemetry to evaluate the relationship between nest-site availability and co-operation. Results illustrate that nest termitaria are higher in the forest canopy, larger in volume and occur in areas with more contiguous canopy cover than unused termitaria. Nest termitaria …

A Complete Species Census And Evidence For Regional Declines In Piping Plovers, Susan M. Haig, Cheron L. Ferland, Francesca J. Cuthbert, Jack Dingledine, J. Paul Goossen, Anne Hecht, Nell Mcphillips

United States Geological Survey: Staff Publications

Complete population estimates for widely distributed species are rarely possible. However, for the third time in 10 years, an International Piping Plover (Charadrius melodus) Breeding and Winter Census was conducted throughout the species range in 2001. Nearly 1,400 participants from 32 U.S. states and Puerto Rico; 9 Canadian provinces; St. Pierre and Miquelon, France; Cuba; and the Bahamas visited 2,244 sites covering 11,836 km of shoreline habitat. During the winter census, 2,389 piping plovers were observed at 33.5% of potentially occupied sites (n = 352). Of these, 56.8% had ≤10 birds present. The breeding census recorded 5,945 adults …

Microclimate And Nest-Site Selection In Micronesian Kingfishers, Dylan C. Kesler, Susan M. Haig Jan 2005

Microclimate And Nest-Site Selection In Micronesian Kingfishers, Dylan C. Kesler, Susan M. Haig

United States Geological Survey: Staff Publications

We studied the relationship between microclimate and nest-site selection in the Pohnpei Micronesian Kingfisher (Todiramphus cinnamominus reichenbachii ) which excavates nest cavities from the mudlike nest structures of arboreal termites (Nasutitermes sp.) or termitaria. Mean daily high temperatures at termitaria were cooler and daily low temperatures were warmer than at random sites in the forest. Results also indicate that termitaria provided insulation from temperature extremes, and that temperatures inside termitaria were within the thermoneutral zone of Micronesian Kingfishers more often than those outside. No differences were identified in temperatures at sites where nest termitaria and nonnest termitaria occurred …

Conservation Genomics: Disequilibrium Mapping Of Domestic Cattle Chromosomal Segments In North American Bison Populations, Natalie D. Halbert, Todd J. Ward, Robert D. Schnabel, Jeremy F. Taylor, James N. Derr

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Introgressive hybridization is one of the major threats to species conservation, and is often induced by human influence on the natural habitat of wildlife species. The ability to accurately identify introgression is critical to understanding its importance in evolution and effective conservation management of species. Hybridization between North American bison ( Bison bison ) and domestic cattle ( Bos taurus ) as a result of human activities has been recorded for over 100 years, and domestic cattle mitochondrial DNA was previously detected in bison populations. In this study, linked microsatellite markers were used to identify domestic cattle chromosomal segments in …

Concentrations Of Cadmium, Lead, And Zinc In Fish From Mining-Influenced Waters Of Northeastern Oklahoma: Sampling Of Blood, Carcass, And Liver For Aquatic Biomonitoring, William G. Brumbaugh, Christopher J. Schmitt, Thomas W. May

United States Geological Survey: Staff Publications

The Tri-States Mining District (TSMD) of Missouri (MO), Kansas (KS), and Oklahoma (OK), USA, was mined for lead (Pb) and zinc (Zn) for more than a century. Mining ceased more than 30 years ago, but wastes remain widely distributed in the region, and there is evidence of surface- and groundwater contamination in the Spring River- Neosho River (SR-NR) system of northeastern OK. In October 2001, we collected a total of 74 fish from six locations in the SR-NR system that included common carp (Cyprinus carpio), channel- and flathead catfish (Ictalurus punctatus and Pylodictis olivaris), largemouth- and spotted bass (Micropterus salmoides …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We summarized the data from the past three TTC (now IMC) meetings to examine the potential trends in presentation of parasites of mammals at the meeting. The lists include titles and authors of papers given in symposia, poster sessions, and oral presentations related to diseases, zoonoses, parasites, and causative agents of diseases of sylvatic mammals. Our analysis shows that there has been an increase in the number of papers (from 2.8% in 1997 to 5.1% in 2005) presented at the International Mammalogical Meetings. We also show that there are potentially more than 27,000 species of parasites (broadly defined) currently inhabiting …

Parasites Of The American White Pelican, Robin M. Overstreet, Stephen S. Curran Jan 2005

Parasites Of The American White Pelican, Robin M. Overstreet, Stephen S. Curran

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Metazoan symbionts, including parasites, infecting the American white pelican (AWP) Pelecanus erythrorhynchos comprise a list of 75 species, 7 of which are new host records. Several new geographic records are also presented, but generally these have a low value because of the migratory nature of the bird. Evidence suggests that some parasites, mostly flies and other arthropods but also nematodes and digeneans, produce detrimental behavioral or pathologic changes in the AWP. Some of the arthropods transmit microbial agents to the pelican. Two digeneans that have the AWP as a definitive host harm and even kill their catfish intermediate host, especially …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report Phrixocephalus cincinnatus, a pennellid copepod infecting the eyes of flatfishes, from a single specimen of rex sole, Glyptocephalus zachirus, for the first time. In the typical host, the arrowtooth flounder, Atherestes stomias, the parasite occurred commonly in sampled populations from the Broughton Archipelago in British Columbia, infected primarily the right eye of the flounder, and on only one occasion presented more than two parasites per eye. The copepod attached to the choroid layer and ramified throughout the posterior compartment of the eye, resulting in the disruption of the retina and probably impairing host vision. Inflammation …

Status Of Oral Rabies Vaccination In Wild Carnivores In The United States, Dennis Slate, Charles E. Rupprecht, Jane A. Rooney, Dennis Donovan, Donald H. Lein, Richard B. Chipman

United States Department of Agriculture Wildlife Services: Staff Publications

Persistence of multiple variants of rabies virus in wild Chiroptera and Carnivora presents a continuing challenge to medical, veterinary and wildlife management professionals. Oral rabies vaccination (ORV) targeting specific Carnivora species has emerged as an integral adjunct to conventional rabies control strategies to protect humans and domestic animals. ORV has been applied with progress toward eliminating rabies in red foxes (Vulpes vulpes) in western Europe and southern Ontario, Canada. More recently since 1995, coordinated ORV was implemented among eastern states in the U.S.A. to prevent spread of raccoon (Procyon lotor) rabies and to contain and eliminate …

Periplasm Organization In Treponema Denticola As Studied By Cryo-Electron Tomography, Jacques Izard, C.-E. Hsieh, C. A. Mannella, Ronald J. Limberger, M. Marko

Department of Food Science and Technology: Faculty Publications

As a spirochete, the genus Treponema is one of the few major bacterial groups whose natural phylogenic relationships are evident at the level of gross phenotypic characteristics such as their morphology. Treponema spp. are highly invasive due to their unique motility in dense media, and their ability to penetrate cell layers. This feature is associated with the helical cell body and the presence of flagellar filaments in the periplasm. Treponema denticola is an oral pathogen involved in endodontic infections and periodontal diseases. The presence and quantity of T. denticola in the subgingival biofilm is correlated with the severity of periodontal …
