Jay Reddy Publications

Myelin proteolipid protein (PLP), the major protein of mammalian CNS myelin, is a member of the proteolipid gene family (pgf). It is an evolutionarily conserved polytopic integral membrane protein and a potential autoantigen in multiple sclerosis (MS). To analyze antibody recognition of PLP epitopes in situ, monoclonal antibodies (mAbs) specific for different regions of human PLP (50–69, 100–123, 139–151, 178–191, 200–219, 264–276) were generated and used to immunostain CNS tissues of representative vertebrates. mAbs to each region recognized whole human PLP on Western blots; the anti-100–123 mAb did not recognize DM-20, the PLP isoform that lacks residues 116–150. All of …

Use Of Sediment Rating Curves And Optical Backscatter Data To Characterize Sediment Transport In The Upper Yuba River Watershed, California, 2001–03, Jennifer A. Curtis, Lorraine E. Flint, Charles N. Alpers, Scott A. Wright, Noah P. Snyder

United States Geological Survey: Publications

Sediment transport in the upper Yuba River watershed, California, was evaluated from October 2001 through September 2003. This report presents results of a three-year study by the U.S. Geological Survey, in cooperation with the California Ecosystem Restoration Program of the California Bay–Delta Authority and the California Resources Agency. Streamflow and suspended-sediment concentration (SSC) samples were collected at four gaging stations; however, this report focuses on sediment transport at the Middle Yuba River (11410000) and the South Yuba River (11417500) gaging stations. Seasonal suspended-sediment rating curves were developed using a group-average method and non-linear least-squares regression. Bed-load transport relations were used …

Cougars In Kansas, Charles D. Lee, Alyssa E. Warneke, Mike Houts, Troy R. Livingston, Philip S. Gipson

United States Geological Survey: Staff Publications

The presence of the cougar (Puma concolor) in the state of Kansas is a controversial issue. Since 1999, 234 cougar sightings have been reported to the Extension Wildlife Specialist at Kansas State University. To those who have reported such sightings, the existence of cougars in Kansas is undeniable. Others, however, question the validity of such sightings as providing evidence of cougars. After surveying other governmental agencies and organizations, we discovered that acceptable identification criteria for rare or unusual felines included things beside sightings: voucher specimens, DNA from hair or scat, tracks, prey carcasses, and photographs or videos. The …

Historical And Current Status Of Elk In Kansas, Jonathan M. Conard, Philip S. Gipson, Matt Peek

United States Geological Survey: Staff Publications

Elk (Cervus elaphus) historically occurred throughout Kansas but were extirpated from the state around 1890. Free-ranging elk populations were reestablished in Kansas through reintroduction efforts on Cimarron National Grasslands from 1981-1990, and on Fort Riley Military Installation from 1986-1994. Current elk distributions in the state have not been published following these reintroduction efforts. The current and historical distribution of this species in Kansas is described.

Measuring Groundwater–Surface Water Interaction And Its Effect On Wetland Stream Benthic Productivity, Trout Lake Watershed, Northern Wisconsin, Usa, Randall J. Hunt, Mac Strand, John F. Walker

United States Geological Survey: Staff Publications

Measurements of groundwater–surface water exchange at three wetland stream sites were related to patterns in benthic productivity as part of the US Geological Survey’s Northern Temperate Lakes–Water, Energy and Biogeochemical Budgets (NTL–WEBB) project. The three sites included one high groundwater discharge (HGD) site, one weak groundwater discharge (WGD) site, and one groundwater recharge (GR) site. Large upward vertical gradients at the HGD site were associated with smallest variation in head below the stream and fewest gradient reversals between the stream and the groundwater beneath the stream, and the stream and the adjacent streambank. The WGD site had the highest number …

Taxonomic Considerations In Listing Subspecies Under The U.S. Endangered Species Act, Susan M. Haig, Erik A. Beever, Steven M. Chambers, Hope M. Draheim, Bruce D. Dugger, Susie M. Dunham, Elise Elliott-Smith, Joseph B. Fontaine, Dylan C. Kesler, Brian J. Knaus, Iara F. Lopes, Pete Loschl, Thomas D. Mullins, Lisa M. Sheffield

United States Geological Survey: Staff Publications

The U.S. Endangered Species Act (ESA) allows listing of subspecies and other groupings below the rank of species. This provides the U.S. Fish and Wildlife Service and the National Marine Fisheries Service with a means to target the most critical unit in need of conservation. Although roughly one-quarter of listed taxa are subspecies, these management agencies are hindered by uncertainties about taxonomic standards during listing or delisting activities. In a review of taxonomic publications and societies, we found few subspecies lists and none that stated standardized criteria for determining subspecific taxa. Lack of criteria is attributed to a centuries-old debate …

Phylogeography And Spatial Genetic Structure Of The Southern Torrent Salamander: Implications For Conservation And Management, Mark P. Miller, Susan M. Haig, R. Steven Wagner

United States Geological Survey: Staff Publications

The Southern torrent salamander (Rhyacotriton variegatus) was recently found not warranted for listing under the US Endangered Species Act due to lack of information regarding population fragmentation and gene flow. Found in small-order streams associated with late-successional coniferous forests of the US Pacific Northwest, threats to their persistence include disturbance related to timber harvest activities. We conducted a study of genetic diversity throughout this species’ range to 1) identify major phylogenetic lineages and phylogeographic barriers and 2) elucidate regional patterns of population genetic and spatial phylogeographic structure. Cytochrome b sequence variation was examined for 189 individuals from 72 …

Importance Of Wetland Landscape Structure To Shorebirds Wintering In An Agricultural Valley, Oriane W. Taft, Susan M. Haig

United States Geological Survey: Staff Publications

Only recently has the influence of landscape structure on habitat use been a research focus in wetland systems. During non-breeding periods when food can be locally limited, wetland spatial pattern across a landscape may be of great importance in determining wetland use. We studied the influence of landscape structure on abundances of wintering Dunlin (Calidris alpina) and Killdeer (Charadrius vociferus) observed on wetlands in the agricultural Willamette Valley of Oregon, USA, during two winters (1999–2000, 2000– 2001) of differing rainfall. We examined (1) shorebird use within a sample of 100 km² regions differing in landscape …

Conserving Biodiversity In Human-Dominated Landscapes, Dale D. Goble, J. Michael Scott, Frank W. Davis

United States Geological Survey: Staff Publications

The two volumes of The Endangered Species Act at Thirty look backward to evaluate the effectiveness of the act over its first three decades (Wilcove and McMillan 2006; Scott et al. 2006, chap. 2; Goble, this volume; Svancara, this volume; Callicott, this volume; Norton, this volume) and also forward to suggest how it can be used as a cornerstone for conserving biological diversity in increasingly human-dominated landscapes (Davis et al. 2006; Bean 2006). The chapters in part 2 of this volume, for example, appraise the science of the 1990s and 2000s at both the large scale (Lomolino, this volume; Naeem …

Critical Habitat, J. Michael Reed, H. Resit Akçakaya, Mark Burgman, Darren Bender, Steven R. Beissinger, J. Michael Scott

United States Geological Survey: Staff Publications

The U.S. Endangered Species Act (ESA) requires that critical habitat-areas essential to the persistence or recovery of a species or population-be identified and protected (Goble and Freyfogle 2002). Despite apprehension that requiring critical habitat designation at the time (or within a year) of listing under the ESA would reduce the rate at which species were listed, this does not appear to have happened (Greenwald et al., this volume; Suckling and Taylor 2006). In fact, critical habitat has been designated for only a fraction of listed species (Scott et al. 2006). Reasons for the poor rate of designation include concerns …

Endangered Species Time Line, Leona K. Svancara, J. Michael Scott, Dale D. Goble, Frank W. Davis, Donna Brewer

United States Geological Survey: Staff Publications

The Endangered Species Act (ESA) is embedded in a web of statutes designed to regulate relationships between humans and other species that stretch back nearly a millennium (Goble, this volume; Goble and Freyfogle 2002). This chapter presents a time line of federal actions taken to protect wildlife beginning with passage of the Land and Water Conservation Fund Act in 1963 (Act of May 28, 1963). Earlier laws to protect wildlife are discussed elsewhere (Goble, this volume). The time line emphasizes federal actions that conserve species at risk of extinction and significant events in the course of implementing the Endangered Species …

Isotope Sourcing Of Prehistoric Willow And Tule Textiles Recovered From Western Great Basin Rock Shelters And Caves: Proof Of Concept, Larry V. Benson, E. M. Hattori, H. E. Taylor, S. R. Poulson, E. A. Jolie

United States Geological Survey: Staff Publications

Isotope and trace-metal analyses were used to determine the origin of plants used to manufacture prehistoric textiles (basketry and matting) from archaeological sites in the western Great Basin. Research focused on strontium (⁸⁷Sr/⁸⁶Sr) and oxygen (¹⁸O/¹⁶O) isotope ratios of willow (Salix sp.) and tule (Schoenoplectus sp.), the dominant raw materials in Great Basin textiles. The oxygen-isotope data indicated that the willow and tule used to produce the textiles were harvested from the banks of rivers or in marshes characterized by flowing water and not from lakes or sinks. The strontium-isotope …

Environmental Contaminants And Biomarker Responses In Fish From The Columbia River And Its Tributaries: Spatial And Temporal Trends, Jo Ellen Hinck, Christopher J. Schmitt, Vicki S. Blazer, Nancy D. Denslow, Timothy M. Bartish, Patrick J. Anderson, James J. Coyle, Gail M. Dethloff, Donald E. Tillitt

United States Geological Survey: Staff Publications

Fish were collected from 16 sites on rivers in the Columbia River Basin (CRB) from September 1997 to April 1998 to document temporal and spatial trends in the concentrations of accumulative contaminants and to assess contaminant effects on the fish. Sites were located on the mainstem of the Columbia River and on the Snake, Willamette, Yakima, Salmon, and Flathead Rivers. Common carp (Cyprinus carpio), black bass (Micropterus sp.), and large-scale sucker (Catostomus macrocheilus) were the targeted species. Fish were field-examined for external and internal lesions, selected organs were weighed to compute somatic indices, and tissue …

Comparison Of Breeding Bird And Vegetation Communities In Primary And Secondary Forests Of Great Smoky Mountains National Park, Theodore R. Simons, Susan A. Shriner, George L. Farnsworth

United States Geological Survey: Staff Publications

We compared breeding bird communities and vegetation characteristics at paired point locations in primary (undisturbed) and mature secondary forest (70–100 years old) sites in Great Smoky Mountains National Park, USA to understand how sites logged prior to creation of the park compare to undisturbed sites following 70 years of protection from human disturbance. We found that bird and vegetation communities are currently similar, but retain some differences in species composition. Rank abundance curves for primary and secondary forest bird communities showed very similar patterns of species dominance. Species composition was also similar on the two sites which shared 24 of …

The Role Of Ground Water In Generating Streamflow In Headwater Areas And In Maintaining Base Flow, Thomas C. Winter

United States Geological Survey: Staff Publications

The volume and sustainability of streamflow from headwaters to downstream reaches commonly depend on contributions from ground water. Streams that begin in extensive aquifers generally have a stable point of origin and substantial discharge in their headwaters. In contrast, streams that begin as discharge from rocks or sediments having low permeability have a point of origin that moves up and down the channel seasonally, have small incipient discharge, and commonly go dry. Nearly all streams need to have some contribution from ground water in order to provide reliable habitat for aquatic organisms. Natural processes and human activities can have a …

The Agricultural Productivity Of Chaco Canyon And The Source(S) Of Pre-Hispanic Maize Found In Pueblo Bonito, Larry Benson, John Stein, Howard Taylor, Richard Friedman, Thomas C. Windes

United States Geological Survey: Staff Publications

Agricultural productivity estimates suggest that the core area of Chaco Canyon could have sustained only a few hundred individuals. Modern analogues of existing Pueblo populations and their domestic habitations with Chaco structures suggest that Chaco at times had a resident population exceeding 2000 people. These data suggest that maize would have had to be imported to feed permanent residents and those visiting Chaco during ritual–political gatherings and those who participated in the accelerated construction and modification of great houses between AD 1030 and 1130. Comparison of strontium-isotope and trace-element ratios of synthetic soil and natural waters from sites within the …

Piezoresponse Force Microscopy And Recent, Alexei Gruverman, Sergei V. Kalinin

Alexei Gruverman Publications

In this paper, we review recent advances in piezoresponse force microscopy (PFM) with respect to nanoscale ferroelectric research, summarize the basic principles of PFM, illustrate what information can be obtained from PFM experiments and delineate the limitations of PFM signal interpretation relevant to quantitative imaging of a broad range of piezoelectrically active materials. Particular attention is given to orientational PFM imaging and data interpretation as well as to electromechanics and kinetics of nanoscale ferroelectric switching in PFM.

Semi-Supervised Conditional Random Fields For Improved Sequence Segmentation And Labeling, Feng Jiao, Shaojun Wang, Chi-Hoon Lee, Russell Greiner, Dale Schuurmans

Kno.e.sis Publications

We present a new semi-supervised training procedure for conditional random fields (CRFs) that can be used to train sequence segmentors and labelers from a combination of labeled and unlabeled training data. Our approach is based on extending the minimum entropy regularization framework to the structured prediction case, yielding a training objective that combines unlabeled conditional entropy with labeled conditional likelihood. Although the training objective is no longer concave, it can still be used to improve an initial model (e.g. obtained from supervised training) by iterative ascent. We apply our new training algorithm to the problem of identifying gene and protein …

Posttraumatic Stress Disorder In Children And Adolescents, Mary R. Driscoll

Graduate Research Papers

Post-traumatic stress disorder in children and adolescents has only been researched for the past fifteen to twenty years. Despite the estimates from state and local child protective services that approximately 896,000 children were victims of child abuse or neglect in 2002 (National Clearinghouse on Child Abuse and Neglect, 2002), the vast majority of research and techniques used in the assessment and treatment of children and adolescents has stemmed from research focused on adults. This report will provide a summary of current perspectives on the definition, assessment, and treatment of PTSD in adolescents.

Can Copyright Lend Its Cinderellaic Magic To Chinese Folklore?, 5 J. Marshall Rev. Intell. Prop. L. 203 (2006), Deming Liu

UIC Review of Intellectual Property Law

Folklore in China is disappearing and facing challenges for its very survival. To salvage folklore in China, some have called for immediate legislative action and proposed the law of copyright or sui generis protection as some potential solutions. However, copyright is traditionally concerned with the creations of individuals rather than the cumulative creations of an ethnic group or region. Furthermore, even sui generis protection, which is better adapted to folklore in theory, could be susceptible in practice to the abuses of private monopolies or state tyranny. Overall, the protection of folklore depends more on a consistent governmental policy of open-mindedness …

Taming The Code: Effectively Implimenting Software Patents, 5 J. Marshall Rev. Intell. Prop. L. 382 (2006), Anthony E. Anderson

UIC Review of Intellectual Property Law

Software patents are a sore subject for many programmers. Although still in their infancy, they have managed to anger many of those in the programming community. Software patents started to evolve in the early 80’s through multiple court decisions that eventually defined software as statutory patentable material. Although patentable, software has proven to be a formidable match for the examination process. The examination process has proven ineffective in properly examining software patent applications and as result multiple lawsuits based on frivolous patents have emerged. Potential battles such as the one between Creative and Apple over Creative’s patent for a hierarchal …

A Comparison Of Presettlement Vegetation And Fire Regimes With Current Patterns In Oak Woodlands And Shrublands Of Sw Oregon, Patricia S. Muir Dr., Paul Hosten Dr.

Joint Fire Science Program Research Project Reports

Fuel reduction efforts on BLM lands in southwestern Oregon are motivated by the need to reduce fire hazard and restore and rehabilitate ecosystems. Successful ecosystem restoration depends, in part, on understanding the target: what ecosystem model is considered natural and healthy for a given area? Oak (Quercus garryana) woodlands and shrublands are two of the most characteristic ecosystems in interior valleys of southwest Oregon, and extensive acreages within these systems are treated annually for fuel reduction. However, these are also two of the least understood ecosystems in the region. We know little about their presettlement attributes, responses to disturbance, or …

Dynamin As A Mover And Pincher During Cell Migration And Invasion, Anne E. Kruchten, Mark A. Mcniven

Faculty Publications

The large GTPase dynamin, long known for its role in endocytosis, has most recently been implicated as a facilitator of cell migration and invasion. Recent observations link dynamin to the cycle of membrane expansion and retraction essential for cell motility. Its role in actin polymerization, membrane deformation and vesiculation, and focal adhesion dynamics are all important for this process, and the new findings provide exciting directions for studies of this ubiquitous and diverse protein family.
