United States Geological Survey: Staff Publications

Approaches using telemetry, precise reproductive assessments, and surgically implanted data storage tags (DSTs) were used in combination with novel applications of analytical techniques for fish movement studies to describe patterns in migratory behavior and predict spawning success of gravid shovelnose sturgeon. From 2004 to 2007, over 300 gravid female shovelnose sturgeon (Scaphirhynchus platorynchus) from the Lower Missouri River, that were expected to spawn in the year they were collected, were surgically implanted with transmitters and archival DSTs. Functional cluster modeling of telemetry data from the spawning season suggested two common migration patterns of gravid female shovelnose sturgeon. Fish …

A fundamental need in conserving species and their habitats is defining distinct entities that range from individuals to species to ecosystems and beyond (Table 1; Ryder 1986, Moritz 1994, Mayden and Wood 1995, Haig and Avise 1996, Hazevoet 1996, Palumbi and Cipriano 1998, Hebert et al. 2004, Mace 2004, Wheeler et al. 2004, Armstrong and Ball 2005, Baker 2008, Ellis et al. 2010, Winker and Haig 2010). Rapid progression in this interdisciplinary field continues at an exponential rate; thus, periodic updates on theory, techniques, and applications are important for informing practitioners and consumers of genetic information. Here, we outline conservation …

Challenges Of Predicting The Potential Distribution Of A Slow-Spreading Invader: A Habitat Suitability Map For An Invasive Riparian Tree, Catherine S. Jarnevich, Lindsay V. Reynolds

United States Geological Survey: Staff Publications

Understanding the potential spread of invasive species is essential for land managers to prevent their establishment and restore impacted habitat. Habitat suitability modeling provides a tool for researchers and managers to understand the potential extent of invasive species spread. Our goal was to use habitat suitability modeling to map potential habitat of the riparian plant invader, Russian olive (Elaeagnus angustifolia). Russian olive has invaded riparian habitat across North America and is continuing to expand its range. We compiled 11 disparate datasets for Russian olive presence locations (n = 1,051 points and 139 polygons) in the western US and …

Evaluating The Effect Of Predators On White-Tailed Deer: Movement And Diet Of Coyotes, Melissa M. Turner, Aimee P. Rockhill, Christopher S. Deperno, Jonathan A. Jenks, Robert W. Klaver, Angela R. Jarding, Troy W. Grovenburg, Kenneth H. Pollock

United States Geological Survey: Staff Publications

Coyotes (Canis latrans) may affect adult and neonate white-tailed deer (Odocoileus virginianus) survival and have been implicated as a contributor to the decline of deer populations. Additionally, coyote diet composition is influenced by prey availability, season, and region. Because coyote movement and diet vary by region, local data are important to understand coyote population dynamics and their impact on prey species. In southeast Minnesota, we investigated the effect of coyotes on white-tailed deer populations by documenting movement rates, distances moved, and habitats searched by coyotes during fawning and nonfawning periods. Additionally, we determined survival, cause-specific mortality, …

Land Change Variability And Human–Environment Dynamics In The United States Great Plains, Mark A, Drummond, Roger F. Auch, Krista A. Karstensen, Kristi L. Sayler, Janis L. Taylor, Thomas Loveland

United States Geological Survey: Staff Publications

Land use and land cover changes have complex linkages to climate variability and change, biophysical resources, and socioeconomic driving forces. To assess these land change dynamics and their causes in the Great Plains, we compare and contrast contemporary changes across 16 ecoregions using Landsat satellite data and statistical analysis. Large-area change analysis of agricultural regions is often hampered by change detection error and the tendency for land conversions to occur at the local-scale. To facilitate a regional-scale analysis, a statistical sampling design of randomly selected 10 km × 10 km blocks is used to efficiently identify the types and rates …

Introduction To “Environmental Contaminants In Biota, 2nd Edition”, W. Nelson Beyer, James P. Meador

United States Geological Survey: Staff Publications

Ecotoxicology is the study of the movement of environmental contaminants through ecosystems and their effects on plants and animals. Examining tissue residues of these contaminants in biota is basic to ecotoxicology, both for understanding the movement of contaminants within organisms and through food chains, and for understanding and quantifying injuries to organisms and their communities. This book provides guidance on interpreting tissue concentrations of environmental contaminants.

Tissue concentrations have long been used both to identify the cause of toxicity in animals and as a measure of the severity of toxicity. More recently, they have been incorporated into environmental models, tying …

Lead In Birds, J. Christian Franson, Deborah J. Pain

United States Geological Survey: Staff Publications

Lead is a highly toxic heavy metal that acts as a nonspecific poison affecting all body systems and has no known biological requirement. Absorption of low concentrations may result in a wide range of sublethal effects in animals, and higher concentrations may result in mortality (Demayo et al. 1982).

Lead has been mined and smelted by humans for centuries, but the use of lead-based products increased greatly following the Industrial Revolution. Consequently, lead today is ubiquitous in air, water, and soil, in both urban and rural environments (Eisler 2000). Vertebrates are exposed to lead mainly via inhalation and ingestion. A …

Spatial Patch Occupancy Patterns Of The Lower Keys Marsh Rabbit, Mitchell J. Eaton, Phillip T. Hughes, James D. Nichols, Anne Morkill, Chad Anderson

United States Geological Survey: Staff Publications

Reliable estimates of presence or absence of a species can provide substantial information on management questions related to distribution and habitat use but should incorporate the probability of detection to reduce bias. We surveyed for the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri) in habitat patches on 5 Florida Key islands, USA, to estimate occupancy and detection probabilities. We derived detection probabilities using spatial replication of plots and evaluated hypotheses that patch location (coastal or interior) and patch size influence occupancy and detection. Results demonstrate that detection probability, given rabbits were present, was <0.5 and suggest that naı¨ve estimates (i.e., estimates without consideration of imperfect detection) of patch occupancy are negatively biased. We found that patch size and location influenced probability of occupancy but not detection. Our findings will be used by Refuge managers to evaluate population trends of Lower Keys marsh rabbits from historical data and to guide management decisions for species recovery. The sampling and analytical methods we used may be useful for researchers and managers of other endangered lagomorphs and cryptic or fossorial animals occupying diverse habitats.

Estimating Age From Recapture Data: Integrating Incremental Growth Measures With Ancillary Data To Infer Age-At-Length, Mitchell J. Eaton, William A. Link

United States Geological Survey: Staff Publications

Estimating the age of individuals in wild populations can be of fundamental importance for answering ecological questions, modeling population demographics, and managing exploited or threatened species. Significant effort has been devoted to determining age through the use of growth annuli, secondary physical characteristics related to age, and growth models. Many species, however, either do not exhibit physical characteristics useful for independent age validation or are too rare to justify sacrificing a large number of individuals to establish the relationship between size and age. Length-at-age models are well represented in the fisheries and other wildlife management literature. Many of these models …

Characteristics Of Road-Kill Locations Of San Clemente Island Foxes, Nathan P. Snow, William F. Andelt, Nicholas P. Gould

United States Department of Agriculture Wildlife Services: Staff Publications

Mortalities from collisions with vehicles have created concern for the welfare of the San Clemente Island fox (Urocyon littoralis clementae); 1 of only 6 genetically distinct subspecies of island fox. To find possible solutions for minimizing these mortalities, we compared 9 characteristics of roads and roadsides at kill-sites and control-sites to ascertain whether certain features were associated with risk of collisions. We found that kill-sites were positively associated with the volume of traffic, and negatively associated with the distance of motorists’ visibility, which had not been previously identified for island foxes. Additionally, visual obstructions along roadsides (i.e., steep …

A Field Evaluation Of A Trap For Invasive American Bullfrogs, Nathan P. Snow, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Native to the eastern United States, American bullfrogs (Rana catesbeiana [Lithobates catesbeianus]) have been introduced in many countries throughout the world. There have been relatively few effective and efficient control methods developed to manage bullfrogs. Particularly in the Hawaiian Islands, Pacific coast of North America, and Japan, finding effective methods for controlling invasive bullfrogs is needed with special emphasis on low impacts for sensitive native species. We conducted a field study to examine the efficacy of a newly designed live trap for capturing invasive bullfrogs. We found that our trap was successful at capturing bullfrogs because we …

Adaptive Resource Management And The Value Of Information, Byron K. Williams, Mitchell J. Eaton, David R. Breininger

United States Geological Survey: Staff Publications

The value of information is a general and broadly applicable concept that has been used for several decades to aid in making decisions in the face of uncertainty. Yet there are relatively few examples of its use in ecology and natural resources management, and almost none that are framed in terms of the future impacts of management decisions. In this paper we discuss the value of information in a context of adaptive management, in which actions are taken sequentially over a timeframe and both future resource conditions and residual uncertainties about resource responses are taken into account. Our objective is …

A Loess–Paleosol Record Of Climate And Glacial History Over The Past Two Glacial–Interglacial Cycles (~150 Ka), Southern Jackson Hole, Wyoming, Kenneth L. Pierce, Daniel R. Muhs, Maynard A. Fosberg, Shannon A. Mahan, Joseph G. Rosenbaum, Joseph M. Licciardi, Milan J. Pavich

United States Geological Survey: Staff Publications

Loess accumulated on a Bull Lake outwash terrace of Marine Oxygen Isotope Stage 6 (MIS 6) age in southern Jackson Hole, Wyoming. The 9 m section displays eight intervals of loess deposition (Loess 1 to Loess 8, oldest), each followed by soil development. Our age-depth model is constrained by thermoluminescence, meteoric ¹⁰Be accumulation in soils, and cosmogenic ¹⁰Be surface exposure ages. We use particle size, geochemical, mineral-magnetic, and clay mineralogical data to interpret loess sources and pedogenesis. Deposition of MIS 6 loess was followed by a tripartite soil/thin loess complex (Soils 8, 7, and 6) apparently re!ecting the …

A Sufficient Condition For The Tops-Only Property Of Strategy-Proof Social Choice Functions In The Case Of Two Voters, Huaxia Zeng

Dissertations and Theses Collection (Open Access)

In this thesis, we consider the standard voting model with a finite set of alternatives A and 2 voters, and address the following question: besides Domains D satisfying the

Property T (Chatterji & Sen (2011) ), what are other characteristics of domains that induce every strategy-proof and unanimous social choice function f : Dn → A to satisfy the tops-only property? We impose a minimal richness condition which ensures that for every alternative a ∈ A, there exists a preference ordering where a is maximal. We identify a more general condition on domains that is sufficient for strategy-proofness …

Pathology, East Africa

Background: Verbal autopsy methods are critically important for evaluating the leading causes of death in populations without adequate vital registration systems. With a myriad of analytical and data collection approaches, it is essential to create a high quality validation dataset from different populations to evaluate comparative method performance and make recommendations for future verbal autopsy implementation. This study was undertaken to compile a set of strictly defined gold standard deaths for which verbal autopsies were collected to validate the accuracy of different methods of verbal autopsy cause of death assignment.

Methods: Data collection was implemented in six sites in four …

Cloth Simulation Using Hardware Tessellation, David Huynh

Theses

Cloth simulation has long been a topic of interest in computer graphics since the early works of Terzopoulos et al. Over the years many techniques have been developed to simulate cloth. Though the general concern has been on the physical accuracy of the simulation. As the simulation gets closer to computational sciences the complexity also increases which at times may come at the cost of real-time performance. With newer and more powerful graphics hardware coming out each year, researchers are starting to shy away from the traditional CPU implementation and turning towards the GPU to offload work. As the parallel …

Ray-Traced Simulation Of Radiation Pressure For Optical Lift, Timothy Peterson

Theses

When light refracts at a surface, it changes the direction and intensity of the light rays. By Newton's 3rd law, this process imparts a small momentum to the object. This effect can be exploited to manipulate very small objects, by carefully selecting the shape and optical properties of the object. This thesis describes a computational model based on the laws of physics to determine the forces and torques resulting from light interacting with a hemicylindrical particle. This model has been successfully used to predict for the first time a phenomenon called optical lift.

Engaging The Legal Academy In Disaster Response, Davida Finger, Laila Hlass, Anne Sikes Hornsby, Susan S. Kuo, Rachel A. Van Cleave

Faculty Scholarship

This article discusses three models of law school engagement that have been used to respond to natural disasters. The three models discussed are a disaster law clinic, a course on disaster law, and a student-led initiative featuring non-credit, pro bono placements. Each model offers a conceptual approach for integrating community-based, justice-oriented initiatives into academic and clinical teaching. Taken as templates for a more permanent model of engagement in the area of post-disaster law and social justice, these models demonstrate that the legal academy can meet its service obligation to the community while training lawyers to better appreciate the central tenets …

Religious And Political Virtues And Values In Congruence Or Conflict?: On Smith, Bob Jones University, And Christian Legal Society, Linda C. Mcclain

Faculty Scholarship

A basic tension in the U.S. constitutional and political order exists between two important ideas about the relationship between civil society and the state: (1) families, religious institutions, voluntary associations, and other groups are foundational sources, or “seedbeds,” of virtues and values that undergird constitutional democracy, and (2) these same institutions guard against governmental orthodoxy and overweening governmental power by generating their own distinctive virtues and values and by being independent locations of power and authority. The first idea envisions a comfortable congruence between civil society and government: the values and virtues - and habits and skills - cultivated in …

Involuntary Servitude, Public Accommodations Laws, And The Legacy Of Heart Of Atlanta Motel V. United States, Linda C. Mcclain

Faculty Scholarship

In Heart of Atlanta Motel v. United States (1964), the U.S. Supreme Court unanimously affirmed Congress’s power under the Commerce Clause to pass Title II, the public accommodations component of the Civil Rights Act of 1964 (CRA). The Johnson Administration expressed hope that this unanimous decision would aid the “reasonable and responsible acceptance” of the CRA. A less familiar legacy of this case is the role played by the Thirteenth Amendment and its declaration that “neither slavery and involuntary servitude . . . shall exist within the United States.” The owner of the Heart of Atlanta Motel unsuccessfully invoked this …

The interface of the database is publicly accessible at http://bucatini.bioinformatics.rit.edu/bindhuURMC/. Even though it is known that influenza viruses are under constant evolution at the surface glycoproteins to develop drug resistance or …

The Second Amendment As Interpreted By Congress And The Court, Sean J. Kealy

Faculty Scholarship

In the last two years, the U.S. Supreme Court has finally offered a reasoned interpretation of the Second Amendment. By the slimmest of majorities in District of Columbia v. Heller and McDonald v. City of Chicago, the Supreme Court held that the Second Amendment supplies an individually-held right to bear arms; the government may place reasonable restrictions on gun ownership, but neither the federal government nor an individual state can deprive a person of their right to possess a handgun. Despite many pages of opinion, however, the majority in Heller offers an unsatisfying explanation for why the Second Amendment …

Les Devoirs De L'Arbitre: Ni Un Pour Tous, Ni Tous Pour Un, William W. Park

Faculty Scholarship

Fans of the Alexandre Dumas novel Three Musketeers will remember that the adventure includes a fourth young man, d'Artagnan, who hopes to become one of the King’s guards, along with his friends Athos, Porthos, and Aramis, living by the motto “All for one, one for all”. Likewise, an arbitrator’s generally include four key obligation: accuracy, fairness, and efficiency, as well as vigilance in promoting an enforceable award. Prevailing litigants normally hope that the arbitral process will lead to something more than a piece of paper. To this end, they expect arbitrators to avoid giving reasons for annulment or non-recognition to …
