Parent Perceptions Of A Child Physical Activity Initiative In A Rural Community., Katie F. Leslie, Kristi M. King, Richard W. Wilson, Patricia Gagne, V. Faye Jones

Faculty and Staff Scholarship

This study assessed the extent to which a community-based intervention developed for children impacted parent perceptions and behaviors toward physical activity in a rural community. Focus groups and individual interviews were conducted with parents of children who participated in physical activity programs. Analysis revealed an increased community awareness surrounding physical activity following program implementation. Parents and children encouraged each other to be physically active. Ecological barriers and enabling factors to adult physical activity were identified these findings indicate a bidirectional influence between parent and child physical activity and the need for community facilities where families can be active together.

Behavioral Responses By Cottonmouths (Agkistrodon Piscivorus) To Chemical And Visual Predator Cues, Kristen Lee Kohlhepp Jan 2016

Behavioral Responses By Cottonmouths (Agkistrodon Piscivorus) To Chemical And Visual Predator Cues, Kristen Lee Kohlhepp

Graduate Theses/Dissertations

Predator detection and assessment of predation risk have important survival consequences for animals. However, responses to predatory threats can vary with different stimuli. Chemical cues are important for predator recognition but visual cues may elicit defensive responses. Cottonmouths (Agkistrodon piscivorus) exhibit an array of antipredatory behaviors that have been thoroughly characterized in response to human aggressors, but their responses to cues from other predators are poorly known. I conducted three experiments to evaluate cottonmouth responses to visual and chemical stimuli from predators and non-predators. Snakes exposed to predator chemical cues exhibited elevated tongue-flick rates compared to controls but did not …


Effect Of Polymer Concentration, Rotational Speed, And Solvent Mixture On Fiber Formation Using Forcespinning, Nancy Obregon, Victor Agubra, Madhab Pokhrel, Howard Campos, David Flores, David De La Garza, Yuanbing Mao, Javier Macossay, Mataz Alcoutlabi Jan 2016

Effect Of Polymer Concentration, Rotational Speed, And Solvent Mixture On Fiber Formation Using Forcespinning, Nancy Obregon, Victor Agubra, Madhab Pokhrel, Howard Campos, David Flores, David De La Garza, Yuanbing Mao, Javier Macossay, Mataz Alcoutlabi

Physics & Astronomy Faculty Publications

Polycaprolactone (PCL) fibers were produced using Forcespinning® (FS). The effects of PCL concentration, solvent mixture, and the spinneret rotational speed on fiber formation were evaluated. The concentration of the polymer in the solvents was a critical determinant of the solution viscosity. Lower PCL concentrations resulted in low solution viscosities with a correspondingly low fiber production rate with many beads. Bead-free fibers with high production rate and uniform fiber diameter distribution were obtained from the optimum PCL concentration (i.e., 12.5 wt%) with tetrahydrofuran (THF) as the solvent. The addition of N, N-dimethylformamide (DMF) to the THF solvent promoted the gradual formation …


Slip-Jump Model For Carbon Combustion Synthesis Of Complex Oxide Nanoparticles, A. A. Markov, Mkhitar A. Hobosyan, Karen S. Martirosyan Jan 2016

Slip-Jump Model For Carbon Combustion Synthesis Of Complex Oxide Nanoparticles, A. A. Markov, Mkhitar A. Hobosyan, Karen S. Martirosyan

Physics & Astronomy Faculty Publications

Carbon Combustion Synthesis of Oxides (CCSO) is a promising method to produce submicron- and nano- sized complex oxides. The CCSO was successfully utilized for producing several complex oxides, a complete theoretical model including the sample porosity, fl ow parameters and reaction energetics is needed to predict the combustion parameters for CCSO. In this work, we studied the ignition temperature and combustion wave axial temperature distribution, activation energy, combustion heat and thermal losses for a typical CCSO synthesis for cylindrical samples of Ni-Zn ferrites with high (>85%) porosity. We developed a two level combustion model of chemically active nano-dispersed mixture, …

Chapter 8 Keeping Wildlife Out Of Your Food: Mitigation And Control Strategies To Reduce The Transmission Risk Of Food-Borne Pathogens, Alan B. Franklin, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

In this chapter, we provide a general framework for developing strategies to mitigate the contamination of agricultural operations with pathogens carried by wildlife. As part of this framework, we present adaptive management as a viable approach to developing these strategies to reduce the uncertainty over time as to whether management methods are being effective. We provide the general steps to developing an adaptive management strategies as well as generic mitigation methods that can be applied to agricultural operations as part of an adaptive management strategy.

Molecular Forensics In Avian Conservation: A Dna‑Based Approach For Identifying Mammalian Predators Of Ground‑Nesting Birds And Eggs, Matthew W. Hopken, Elizabeth K. Orning, Julie K. Young, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Background: The greater sage-grouse (Centrocercus urophasianus) is a ground-nesting bird from the Northern Rocky Mountains and a species at risk of extinction in in multiple U.S. states and Canada. Herein we report results from a proof of concept that mitochondrial and nuclear DNAs from mammalian predator saliva could be non-invasively collected from depredated greater sage-grouse eggshells and carcasses and used for predator species identification. Molecular forensic approaches have been applied to identify predators from depredated remains as one strategy to better understand predator–prey dynamics and guide management strategies. This can aid conservation efforts by correctly identifying predators most …


Photographic Estimation Of Wild Boar Damage To Alpine Grazing Pastures In The Carpathian Mountains Of Central Romania, Richard M. Engeman, Renate Cattaruzza, Marco Cattaruzza, Justin W. Fischer Jan 2016

Photographic Estimation Of Wild Boar Damage To Alpine Grazing Pastures In The Carpathian Mountains Of Central Romania, Richard M. Engeman, Renate Cattaruzza, Marco Cattaruzza, Justin W. Fischer

United States Department of Agriculture Wildlife Services: Staff Publications

Observations of wild boar damage to alpine grazing pastures in Romania’s Carpathian Mountains were collected using photographs of the slopes from vantage points. We mapped the rooted areas and then used GIS software to estimate the relative proportions of the total grazing areas visible in the photographs that were damaged by wild boar. The amounts of damage from our two demonstration pastures were 11.2 and 13.5 %. Pastures are rented for summer grazing with grazing density monitored. Wild boar damage essentially decreases the economic benefit received for the cost of the grazing rights. This paper appears to be the first …


Defending Against Disparate Marine Turtle Nest Predators: Nesting Success Benefits From Eradicating Invasive Feral Swine And Caging Nests From Raccoons, Richard M. Engeman, David Addison, J. C. Griffin Jan 2016

Defending Against Disparate Marine Turtle Nest Predators: Nesting Success Benefits From Eradicating Invasive Feral Swine And Caging Nests From Raccoons, Richard M. Engeman, David Addison, J. C. Griffin

United States Department of Agriculture Wildlife Services: Staff Publications

Nest predation can threaten marine turtle nesting success, and having to address dissimilar predator species complicates nest protection efforts. On Florida’s Keewaydin Island predation by raccoons Procyon lotor and invasive feral swine Sus scrofa are disparate, significant threats tomarine turtle nests. Using 6 years of nesting data (mostly for loggerhead marine turtles Caretta caretta) we examined the impacts of swine predation on nests and the benefits of swine eradication, caging nests to protect them from raccoon predation, and the effects of nest caging on swine predation. Nest predation by swine began in mid nesting season 2007, after which swine …

Report To The Chicago Park District On Conflicts With Ring-Billed Gulls And The 2015 Integrated Ring-Billed Gull Damage Management Project, M. L. Bloomquist, J.W. Hartmann, C.K. Pullins, T.G. Guerrant, S. F. Beckerman, R. M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The large ring-billed gull (Larus delawarensis) population in the City of Chicago has caused various conflicts including general nuisance, property damage, economic losses, and threats to human health and safety. Several studies have shown a relationship between ring-billed gulls and increased levels of fecal indicator bacteria (FIB) such as Escherichia coli (E. coli) in nearshore waters. Results of tests for E. coli have led to the issuance of swim advisories at Chicago beaches. The objectives of the Chicago Ring-billed Gull Damage Management Project were to (1) reduce the local production of ring-billed gulls, (2) reduce the …


Guiding The Management Of An Agricultural Pest: Indexing Abundance Of California Meadow Voles In Artichoke Fields, Richard M. Engeman, Roger A. Baldwin, Denise I. Stetson Jan 2016

Guiding The Management Of An Agricultural Pest: Indexing Abundance Of California Meadow Voles In Artichoke Fields, Richard M. Engeman, Roger A. Baldwin, Denise I. Stetson

United States Department of Agriculture Wildlife Services: Staff Publications

Nearly 100% of U.S. artichoke production comes from California and is concentrated in Monterey County. California meadow voles are damaging rodent pests that can threaten the profitability of growing artichokes. A practical population monitoring method can be invaluable to integrated pest management programs for guiding when and where control is needed and assessing control efficacy. The standard method for indexing vole populations in artichoke fields has been based on observing chewing on artichoke bracts placed throughout the field. Because toxicants are delivered on artichoke bracts, bias for population indexing is potentially introduced. We therefore compared artichoke bracts to nontoxic grain-based …

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Understanding predator–prey relationships is important for making informed management decisions. Knowledge of jaguar (Panthera onca) predation on livestock and native prey is imperative for future conservation of jaguars in Central and South America.

Aim. As part of an investigation to determine predation patterns of jaguars in the southern Pantanal, Brazil, we examined spatial, temporal and habitat variables, which are useful in categorising location clusters as kill sites and non-kill sites.

Methods. Using GPS-collars on 10 jaguars we obtained a total of 11 784 locations, from which 877 clusters were identified, visited and examined for …


Integrating Early Detection With Dna Barcoding: Species Identification Of A Nonnative Monitor Lizard (Squamata: Varanidae) Carcass In Mississippi, U.S.A., Robert N. Reed, Matthew W. Hopken, David Steensen, Bryan G. Falk, Antoinette J. Piaggio Jan 2016

Integrating Early Detection With Dna Barcoding: Species Identification Of A Nonnative Monitor Lizard (Squamata: Varanidae) Carcass In Mississippi, U.S.A., Robert N. Reed, Matthew W. Hopken, David Steensen, Bryan G. Falk, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Early detection of invasive species is critical to increasing the probability of successful management. At the primary stage of an invasion, invasive species are easier to control as the population is likely represented by just a few individuals. Detection of these first few individuals can be challenging, particularly if they are cryptic or otherwise characterized by low detectability. The engagement of members of the public may be critical to early detection as there are far more citizens on the landscape than trained biologists. However, it can be difficult to assess the credibility of public reporting, especially when a diagnostic digital …


No Filters, No Fridges: A Method For Preservation Of Water Samples For Edna Analysis, Kelly E. Williams, Kathryn P. Huyvaert, Antoinette J. Piaggio Jan 2016

No Filters, No Fridges: A Method For Preservation Of Water Samples For Edna Analysis, Kelly E. Williams, Kathryn P. Huyvaert, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Background: Advancements in the detection of environmental DNA (eDNA) for detecting species of interest will likely allow for expanded use of these techniques in the field. One obstacle that continues to hinder applications in the field is the requirement of a cold chain of storage for water samples containing eDNA. While eDNA has been successfully preserved using Longmire’s lysis buffer applied to filters, it has yet to be tried with freshwater samples collected for eDNA detection of an invasive species. We tested the utility of Longmire’s solution (100 mM Tris, 100 mM EDTA, 10 mM NaCl, 0.5 % SDS, 0.2 …


Resource Selection By Cougars: Influence Of Behavioral State And Season, Linsey W. Blake, Eric M. Gese Jan 2016

Resource Selection By Cougars: Influence Of Behavioral State And Season, Linsey W. Blake, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

An understanding of how a predator uses the landscape can assist in developing management plans. We modeled resource selection by cougars (Puma concolor) during 2 behavioral states (moving and killing) and 2 seasons (summer and winter) with respect to landscape characteristics using locations from global positioning system (GPS)-collared cougars in the Pryor Mountains, Montana and Wyoming, USA. Furthermore, we examined predation-specific resource selection at 2 scales (fine and coarse). When possible, we backtracked from cache sites to kill sites and used a fine-scale analysis to examine landscape characteristics of confirmed kills. At this fine scale, kill sites had …

Frugivorous birds impose significant costs on tree fruit growers through direct consumption of fruit and grower efforts to manage birds.We documented factors that influenced tree fruit bird damage from 2012 through 2014 with a coordinated field study in Michigan, New York, and Washington. For sweet cherries, percent bird damage was higher in 2012 compared to 2013 and 2014, in Michigan and New York compared toWashington, and in blocks with more edges adjacent to non-sweet cherry land-cover types. These patterns appeared to be associated with fruit abundance patterns; 2012 was a particularly lowyield year for tree fruits in Michigan and New …

United States Department of Agriculture Wildlife Services: Staff Publications

The high levels of human demands of resources—from food to space and energy—are one of the main drivers of global change and are causing large negative impacts on ecosystems functioning worldwide (Vitousek et al. 1997 ). Global change components range from climate change to habitat destruction, species invasions, pollution and eutrophication. Although these factors can produce ecosystem changes independently, the final descent is often driven by synergistic processes. The resulting amplifying feedbacks can be disconnected from the original driver of change, leading to a state shift in the biosphere with unexpected consequences (Barnosky et al. 2012 ). Climate change seems …


Chapter 3: One Health, One Medicine, Laura H. Kahn, Thomas P. Monath, Bob H. Bokma, E. Paul Gibbs, A. Alonso Aguirre Jan 2016

Chapter 3: One Health, One Medicine, Laura H. Kahn, Thomas P. Monath, Bob H. Bokma, E. Paul Gibbs, A. Alonso Aguirre

United States Department of Agriculture Wildlife Services: Staff Publications

In recognition that the health of humans, animals, and the environment is linked, One Health seeks to increase communication and collaboration across the disciplines in order to promote, improve, and defend the health of all species on the planet. This strategy may seem simple, but unfortunately it will not be easy to implement. The explosion of medical knowledge in the 20th century led to academic, governmental, and industrial silos of specialization; these silos fostered a compartmentalized approach to health and disease. Building bridges across these silos will require leadership, joint educational programs, financial support, and other strategies that promote transdisciplinary …


Olfactory Attractants And Parity Affect Prenatal Androgens And Territoriality Of Coyote Breeding Pairs, Christopher J. Schell, Julie K. Young, Elizabeth V. Lonsdorf, Jill M. Mateo, Rachel M. Santymire Jan 2016

Olfactory Attractants And Parity Affect Prenatal Androgens And Territoriality Of Coyote Breeding Pairs, Christopher J. Schell, Julie K. Young, Elizabeth V. Lonsdorf, Jill M. Mateo, Rachel M. Santymire

United States Department of Agriculture Wildlife Services: Staff Publications

Hormones are fundamental mediators of personality traits intimately linked with reproductive success. Hence, alterations to endocrine factors may dramatically affect individual behavior that has subsequent fitness consequences. Yet it is unclear how hormonal or behavioral traits change with environmental stressors or over multiple reproductive opportunities, particularly for biparental fauna. To simulate an environmental stressor, we exposed captive coyote (Canis latrans) pairs to novel coyote odor attractants (i.e. commercial scent lures) midgestation to influence territorial behaviors, fecal glucocorticoid (FGMs) and fecal androgen metabolites (FAMs). In addition, we observed coyote pairs as first-time and experienced breeders to assess the influence …


Environmental Factors Influencing The Occurrence Of Coyotes And Conflicts In Urban Areas, Sharon A. Poessel, Eric M. Gese, Julie K. Young Jan 2016

Environmental Factors Influencing The Occurrence Of Coyotes And Conflicts In Urban Areas, Sharon A. Poessel, Eric M. Gese, Julie K. Young

United States Department of Agriculture Wildlife Services: Staff Publications

The increase of global urbanization can have effects on wildlife species, including carnivores such as coyotes (Canis latrans). As coyotes continue to settle in more urban areas, reports of human-coyote conflicts, such as attacks on humans or pets, may also increase. Understanding environmental variables that might influence whether or not coyotes and human-coyote conflicts will occur in certain urban areas may assist wildlife officials in creating management plans for urban wildlife.We conducted a survey of 105 urban areas in the United States requesting information on the occurrence of coyotes and human-coyote conflicts. We analyzed the responses with data …


Morphometric Variation During Chick Development In Interior Double-Crested Cormorants (Phalacrocorax Auritus), Jennifer E. Chastant, Corey T. Callaghan, D. Tommy King Jan 2016

Morphometric Variation During Chick Development In Interior Double-Crested Cormorants (Phalacrocorax Auritus), Jennifer E. Chastant, Corey T. Callaghan, D. Tommy King

United States Department of Agriculture Wildlife Services: Staff Publications

In numerous avian species, egg size is correlated to female body condition, hatchling size and nestling growth. Recent demography studies of Interior Double-crested Cormorants (Phalacrocorax auritus) suggest a migratory divide across the Great Lakes; western populations winter in the Gulf of Mexico region of the southeastern United States (Alabama, Arkansas, Louisiana, and Mississippi) with extensive catfish (Ictalurus punctatus) aquaculture, and eastern populations winter in Florida, where catfish aquaculture is not pervasive. If Double-crested Cormorants have improved their overall body condition through catfish exploitation, then egg and chick sizes should also be affected. Three breeding areas in Ontario (east, central, and …

Bait Flavor Preference And Immunogenicity Of Onrab Baits In Domestic Dogs On The Navajo Nation, Arizona, Are R. Berentsen, Scott Bender, Peggy Bender, David Bergman, Amy T. Gilbert, Hannah M. Rowland, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies is responsible for an estimated 59,000 human deaths worldwide, and domestic dogs are the primary reservoir and vector of the disease. Among some nations, widespread vaccination has led to elimination of rabies in domestic dogs, yet dogs are still susceptible to rabies infection from interactions with wildlife reservoirs. On Tribal lands in the United States, less than 20% of domestic dogs are vaccinated for rabies, and parenteral vaccination is often unfeasible. Oral rabies vaccination may provide a solution, but a suitable bait flavor and vaccine must be identified. We evaluated 5 bait flavors (bacon, cheese, egg, fish, and sweet) …

Prioritizing Management And Research Actions Against Invasive Reptiles In Florida: A Collaboration By An Expert Panel, Richard M. Engeman, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

Florida has more introduced animals than any other region of the U.S. and also ranks high in this respect globally. Given Florida's climate, it is no coincidence that a large proportion of Florida’s invasive vertebrate species are reptiles and amphibians. Exotic snakes, lizards, frogs, turtles, and crocodilians are all breeding in Florida. The largest snakes in Florida are constrictors from other continents, and the five largest lizard species breeding in Florida are from Africa, South America, and Central America. Establishment of non-native reptiles and amphibians has been documented in Florida for over 135 years, and the rate of invasive reptile …

Heartland virus (HRTV) is a recently described phlebovirus initially isolated in 2009 from 2 humans who had leukopenia and thrombocytopenia. Serologic assessment of domestic and wild animal populations near the residence of 1 of these persons showed high exposure rates to raccoons, white-tailed deer, and horses. To our knowledge, no laboratory-based assessments of viremic potential of animals infected with HRTV have been performed. We experimentally inoculated several vertebrates (raccoons, goats, chickens, rabbits, hamsters, C57BL/6 mice, and interferon-α/β/γ receptor–deficient [Ag129]) mice with this virus. All animals showed immune responses against HRTV after primary or secondary exposure. However, neutralizing antibody responses were …

Cougar Predation Rates And Prey Composition In The Pryor Mountains Of Wyoming And Montana, Linsey W. Blake, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding predator-prey dynamics is a fundamental principle of ecology and an ideal component for management decisions. Across North America, the impact of cougars (Puma concolor) on their prey varies regionally. To document the relationships between cougars, bighorn sheep (Ovis canadensis canadensis), mule deer (Odocoileus hemionus), and feral horses (Equus caballus) on the Bighorn Canyon National Recreation Area and the Pryor Mountains, we deployed GPS collars on 6 cougars (the total number residing on the study area), and visited their clusters to determine predation rates and foraging patterns. We examined the composition of …


Seasonal Evolution Of Active Layer Formation In Subarctic Peat Plateaux And Implications For Dissolved Organic Matter Composition And Transfer, Jennifer L. Hickman Jan 2016

Seasonal Evolution Of Active Layer Formation In Subarctic Peat Plateaux And Implications For Dissolved Organic Matter Composition And Transfer, Jennifer L. Hickman

Theses and Dissertations (Comprehensive)

Peat-accumulating wetlands are ecosystems whose rate of photosynthetic production of organic matter is greater than that of its decomposition, resulting in a build up of soil organic matter that may take centuries to fully decompose. Carbon (C) stocks within these ecosystems are a function of inputs from photosynthesis, and losses from heterotrophic decomposition. Due to the short growing season and overall cold climate of boreal and tundra regions, C has been accumulating within these landscapes, mostly in soil organic matter, since the last glaciation. Climate change, predicted to result in rising temperatures and increased precipitation, has begun to degrade the …
