Fishing Diseased Abalone To Promote Yield And Conservation, Tal Ben-Horin, Kevin D. Lafferty, Gorka Bidegain, Hunter S. Lenihan

United States Geological Survey: Staff Publications

Past theoretical models suggest fishing disease-impacted stocks can reduce parasite transmission, but this is a good management strategy only when the exploitation required to reduce transmission does not overfish the stock. We applied this concept to a red abalone fishery so impacted by an infectious disease (withering syndrome) that stock densities plummeted and managers closed the fishery. In addition to the non-selective fishing strategy considered by past disease- fishing models, we modelled targeting (culling) infected individuals,which is plausible in red abalone because modern diagnostic tools can determine infection without harming landed abalone and the diagnostic cost is minor relative to …

Coherent Late-Holocene Climate-Driven Shifts In The Structure Of Three Rocky Mountain Lakes, Jeffrey R. Stone, Jasmine E. Saros, Gregory T. Pederson

United States Geological Survey: Staff Publications

Large-scale atmospheric pressure centers, such as the Aleutian and Icelandic Low, have a demonstrated relationship with physical lake characteristics in contemporary monitoring studies, but the responses to these phenomena are rarely observed in lake records. We observe coherent changes in the stratification patterns of three deep (>30 m) lakes inferred from fossil diatom assemblages as a response to shifts in the location and intensity of the Aleutian Low and compare these changes with similar long-term changes observed in the ¹⁸O record from the Yukon. Specifically, these records indicate that between 3.2 and 1.4 ka, the Aleutian Low shifted …

Supplementary Feeding And Endangered Avian Scavengers: Benefits, Caveats, And Controversies, Ainara Cortés- Avizanda, Guillermo Blanco, Travis L. Devault, Anil Markandya, Munir Z Virani, Joseph Brandt, José A Donázar

United States Department of Agriculture Wildlife Services: Staff Publications

Large avian scavengers are among the most vulnerable vertebrates, and many of their populations have declined severely in recent decades. To help mitigate this marked reduction in abundance, supplementary feeding stations (SFS; colloquially termed “vulture restaurants”) have been created worldwide, often without consideration of the scientific evidence supporting the suitability of the practice. SFS have been effective and important tools for conservation and reintroduction of avian scavengers. However, negative consequences can result from large aggregations of individual birds, disrupting intraguild processes and promoting density-dependent decreases in productivity. At the community level, SFS favor the congregation of predators (ie facultative scavengers), …

Disease-Emergence Dynamics And Control In A Socially-Structured Wildlife Species, Kim M. Pepin, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Once a pathogen is introduced in a population, key factors governing rate of spread include contact structure, supply of susceptible individuals and pathogen life-history. We examined the interplay of these factors on emergence dynamics and efficacy of disease prevention and response. We contrasted transmission dynamics of livestock viruses with different life-histories in hypothetical populations of feral swine with different contact structures (homogenous, metapopulation, spatial and network). Persistence probability was near 0 for the FMDV-like case under a wide range of parameter values and contact structures, while persistence was probable for the CSFV-like case. There were no sets of conditions where …

Limited Transmission Of Emergent H7n9 Influenza A Virus In A Simulated Live Animal Market: Do Chickens Pose The Principal Transmission Threat?, Angela Bosco-Lauth, Richard A. Bowen, J. Jeffrey Root

United States Department of Agriculture Wildlife Services: Staff Publications

Emergent H7N9 influenza A virus has caused multiple public health and financial hardships. While some epidemiological studies have recognized infected chickens as an important bridge for human infections, the generality of this observation, the minimum infectious dose, and the shedding potential of chickens have received conflicting results. We experimentally tested the ability of domestic chickens (Gallus gallus domesticus) to transmit H7N9 to co-housed chickens and to several other animal species in an experimental live animal market. Results indicated that an infected chicken failed to initiate viral shedding of H7N9 to naIve co-housed chickens. The infected chicken did, however, …

High Rates Of Detection Of Clade 2.3.4.4 Highly Pathogenic Avian Influenza H5 Viruses In Wild Birds In The Pacific Northwest During The Winter Of 2014–15, Hon S. Ip, Robert J. Dusek, Barbara Bodenstein, Mia Kim Torchetti, Paul Debruyn, Kristin Mansfield, Thomas J. Deliberto, Jonathan M. Sleeman

United States Department of Agriculture Wildlife Services: Staff Publications

SUMMARY. In 2014, clade 2.3.4.4 H5N8 highly pathogenic avian influenza (HPAI) viruses spread across the Republic of Korea and ultimately were reported in China, Japan, Russia, and Europe. Mortality associated with a reassortant HPAI H5N2 virus was detected in poultry farms in western Canada at the end of November. The same strain (with identical genetic structure) was then detected in free-living wild birds that had died prior to December 8, 2014, of unrelated causes in Whatcom County, Washington, U. S. A., in an area contiguous with the index Canadian location. A gyrfalcon (Falco rusticolus) that had hunted and …

Outbreak Of H7n8 Low Pathogenic Avian Influenza In Commercial Turkeys With Spontaneous Mutation To Highly Pathogenic Avian Influenza, Mary Lea Killian, Mia Kim Torchetti, Nichole Hines, Sam Yingst, Thomas J. Deliberto, Dong-Hun Lee

United States Department of Agriculture Wildlife Services: Staff Publications

Highly pathogenic avian influenza (HPAI) subtype H7N8 was detected in commercial turkeys in January 2016. Control zone surveillance discovered a progenitor low pathogenic avian influenza (LPAI) virus in surrounding turkey flocks. Data analysis supports a single LPAI virus introduction followed by spontaneous mutation to HPAI on a single premises.

Highly Pathogenic Avian Influenza Viruses And Generation Of Novel Reassortants, United States, 2014–2015, Dong-Hun Lee, Justin Bahl, Mia Kim Torchetti, Mary Lea Killian, Hon S. Ip, Thomas J. Deliberto, David E. Swayne

United States Department of Agriculture Wildlife Services: Staff Publications

Asian highly pathogenic avian influenza A(H5N8) viruses spread into North America in 2014 during autumn bird migration. Complete genome sequencing and phylogenetic analysis of 32 H5 viruses identified novel H5N1, H5N2, and H5N8 viruses that emerged in late 2014 through reassortment with North American low-pathogenicity avian influenza viruses.

A Noninvasive Method To Detect Mexican Wolves And Estimate Abundance, Antoinette J. Piaggio, Chip.A. Cariappa, Dyan J. Straughan, Melissa Neubaum, Margaret Dwire, Paul R. Krausman, Warren B. Ballard, David L. Bergman, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Monitoring wolf abundance is important for recovery efforts of Mexican wolves (Canis lupus baileyi) in the Blue Range Wolf Recovery Area in Arizona and New Mexico, USA. Although radiotelemetry has been a reliable method, collaring and tracking wolves in an expanding population will be prohibitively expensive and alternative methods to estimate abundance will become necessary. We applied 10 canid microsatellite loci to 235 Mexican wolf samples, 48 coyote (C. latrans) samples, and 14 domestic dog (C. lupus familiaris) samples to identify alleles that provide reliable separation of these species. We then evaluated an approach …

Ecosystem Services Provided By Avian Scavengers, Travis L. Devault, James C. Beasley, Zachary H. Olson, Marcos Moleón, Martina Carrete, Antoni Margalida, José Antonio Sánchez-Zapata

United States Department of Agriculture Wildlife Services: Staff Publications

Food webs developed under classical theoretical models often depict simplistic interactions among trophic levels linked by predation (Hairston et al. 1960). As a result, extensive research efforts have been devoted to studying predator-prey interactions, often ignoring the contribution of scavenging in food-web dynamics. However, recent advancements in food-web theory have recognized the widespread and critical role that scavenging plays in stabilizing food webs in ecosystems throughout the world, thus suggesting that previous models may have greatly underestimated the importance of scavenging in food web research ( Wilson and Wolkovich 2011; Barton et al. 2013). Such disregard for the importance of …

Proportions Of Bird Damage In Tree Fruits Are Higher In Low-Fruit-Abundance Contexts, Catherine A. Lindell, Karen M.M. Steensma, Paul D. Curtis, Jason R. Boulanger, Juliet E. Carroll, Colleen Burrows, David P. Lusch, Nikki L. Rothwell, Shayna L. Wieferich, Heidi M. Henrichs, Deanna K. Leigh, Rachael A. Eaton, George M. Linz

United States Department of Agriculture Wildlife Services: Staff Publications

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 …

Feral Swine Damage To Globally Imperiled Wetland Plant Communities In A Significant Biodiversity Hotspot In Florida, Richard M. Engeman, Steve L. Orzell, Rodney K. Felix, Eric A. Tillman, Gary Killian, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

We studied rooting damage during five-years of feral swine control at Avon Park Air Force Range, a significant botanical biodiversity hotspot in peninsular Florida with many globally imperiled plant species and communities. While control reduced swine abundance, remaining animals consistently rooted the 49 studied sites in both middle-dry season (MDS) and late-dry season (LDS) each year. At each study site, we measured rooting with sub-meter accuracy. Neither total nor proportional area rooted differed in either season, across study years, or among plant community types: herbaceous seepage slopes, wet pine savannas, wet grasslands. The proportion of sites with damage during MDS …

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 …

Evaluation Of Boldness Assays And Associated Behavioral Measures In A Social Parrot, Monk Parakeet (Myiopsitta Monachus), Kaan Kerman, Kathryn E. Sieving, Colette S. Mary, Michael L. Avery

United States Department of Agriculture Wildlife Services: Staff Publications

Boldness reflects consistent individual differences in risk-taking behavior across various contexts. However, evaluating this basic assumption has largely been neglected in birds. In a captive monk parakeet population (Myiopsitta monachus; N = 33), we undertook an analysis of 7 measures across 3 commonly used boldness assays (i.e., novel object, emergence, and predator-exposure tests). Using principal component analysis, we derived 3 components (PCs). PC-2 loaded strongly with measures from emergence and predator-exposure tests; we interpreted it as the closest approximation of boldness. PC-1 and PC-3 described different aspects of feeding such as foraging activity and rate, respectively. Finally, we …

New Study Underway To Estimate The Impact Of Lesser Scaup On Arkansas’ Baitfish Industry, Stephen Clements, Brian Davis, Brian S. Dorr, Luke A. Roy, Anita M. Kelly, Carole R. Engle

United States Department of Agriculture Wildlife Services: Staff Publications

The baitfish industry is an important economic enterprise for many aquaculture producers in Arkansas. The industry generates approximately $30 million annually in farm-gate sales of these small fish that include fathead minnows, goldfish and golden shiners. Diving ducks known as scaup, or “Bluebills,” spend late fall through early spring in Arkansas and Mississippi on deep water wetlands, rivers, and aquaculture ponds. The notion that scaup are consuming an abundance of baitfish in Arkansas ponds has concerned commercial growers for several years.

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 …

Role For Migratory Wild Birds In The Global Spread Of Avian Influenza H5n8

United States Department of Agriculture Wildlife Services: Staff Publications

Avian influenza viruses affect both poultry production and public health. A subtype H5N8 (clade 2.3.4.4) virus, following an outbreak in poultry in South Korea in January 2014, rapidly spread worldwide in 2014–2015. Our analysis of H5N8 viral sequences, epidemiological investigations, waterfowl migration, and poultry trade showed that long-distance migratory birds can play a major role in the global spread of avian influenza viruses. Further, we found that the hemagglutinin of clade 2.3.4.4 virus was remarkably promiscuous, creating reassortants with multiple neuraminidase subtypes. Improving our understanding of the circumpolar circulation of avian influenza viruses in migratory waterfowl will help to provide …

Antigenic Characterization Of H3 Subtypes Of Avian Influenza A Viruses From North America, Elizabeth Bailey, Li-Ping Long, Nan Zhao, Jeffrey S. Hall, John A. Baroch, Jacqueline M. Nolting, Lucy Senter, Frederick L. Cunningham, G. Todd Pharr, Larry Hanson, Richard Slemons, Thomas J. Deliberto, Xiu-Feng Wan

United States Department of Agriculture Wildlife Services: Staff Publications

Besides humans, H3 subtypes of influenza A viruses (IAVs) can infect various animal hosts, including avian, swine, equine, canine, and sea mammal species. These H3 viruses are both antigenically and genetically diverse. Here, we characterized the antigenic diversity of contemporary H3 avian IAVs recovered from migratory birds in North America. Hemagglutination inhibition (HI) assays were performed on 37 H3 isolates of avian IAVs recovered from 2007 to 2011 using generated reference chicken sera. These isolates were recovered from samples taken in the Atlantic, Mississippi, Central, and Pacific waterfowl migration flyways. Antisera to all the tested H3 isolates cross-reacted with each …

Effects Of Visual Obstruction, Prey Resources, And Satiety On Bird Use Of Simulated Airport Grasslands, Bradley F. Blackwell, Thomas W. Seamans, Kimberly Linnell, Lisa Kutschbach-Brohl, Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Grasslands represent 39%–50% of U.S. airport properties, and a recent management framework recommended exploiting both antipredator behaviours and food resources in airport grasslands to curb use by birds considered hazardous to aviation safety. We evaluated framework predictions empirically by exposing unsated and sated brown-headed cowbirds (Molothrus ater) to visually obstructive (∼13-cm vegetation height; tall), higher-risk plots versus unobstructive (height; short) plots, and relative to prey resources. We predicted that 1) unsated birds (unfed since the previous day) would be present in greater numbers and forage more in short than tall vegetation plots 24 h post-mowing because of invertebrate …

Widespread Detection Of Antibodies To Eastern Equine Encephalitis, West Nile, St. Louis Encephalitis, And Turlock Viruses In Various Species Of Wild Birds From Across The United States, Kerri Pedersen, David R. Marks, Eryu Wang, Gillian Eastwood, Scott C. Weaver, Samuel M. Goldstein, David R. Sinnett, Thomas J. Deliberto

United States Department of Agriculture Wildlife Services: Staff Publications

Wild birds serve as amplifying hosts for many arboviruses, and are thought to be responsible for introducing these viruses into new areas during migration as well as reintroducing them to places where winter temperatures disrupt mosquito-borne transmission. To learn more about four mosquito-borne arboviruses of concern to human or animal health, we tested sera from 997 wild birds of 54 species and 17 families across 44 states of the United States collected from January 1, 2013, through September 30, 2013. Samples were tested for antibody against eastern equine encephalitis, St. Louis encephalitis, West Nile, and Turlock viruses using plaque reduction …

Weak Support For Disappearance And Restricted Emergence/Persistence Of Highly Pathogenic Influenza A In North American Waterfowl, Andrew M. Ramey, Erica Spackman, Mia Kim-Torchetti, Thomas J. Deliberto

United States Department of Agriculture Wildlife Services: Staff Publications

Krauss et al. (1) use lack of detection of highly pathogenic (HP) H5 clade 2.3.4.4 (henceforth “H5”) influenza A viruses (IAVs) from >22,000 wild bird samples collected in North America in 2014–2015 to argue that HP H5 IAVs disappeared from waterfowl and that unresolved mechanisms restrict emergence and perpetuation of HP IAVs in natural reservoir species. Here we offer an alternative interpretation.

Use Of Predator Hair To Enhance Perceived Risk To White-Tailed Deer In A Foraging Context, Thomas W. Seamans, Bradley F. Blackwell, Kimberly E. Linnell

United States Department of Agriculture Wildlife Services: Staff Publications

Deer react to predator scent in varying degrees even when exposed to unknown predators. This response could be genetically based and maintained as long as the population is exposed to predation. We tested whether predator scent in the form of hair would enhance perceived risk and serve as a foraging repellent to free-ranging white-tailed deer (Odocoileus virginianus). During the winters of 2013 and 2014, we quantifi ed alert behaviors and consumption of whole-kernel corn in response to current (coyote [Canis latrans]) and extirpated (bobcat [Lynx rufus]; black bear [Ursus americanus]) predator species …

Repellent Application Strategy For Wild Rodents And Cottontail Rabbits, Scott J. Werner, Shelagh T. Deliberto, Roger A. Baldwin, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Effective chemical repellents and repellent application strategies are needed to manage damages caused by wild rodents and rabbits to agricultural resources. For the purpose of comparatively investigating the behavioral response of wild rodents and rabbits to a chemical repellent, we experimentally evaluated the concentration-response relationship of an anthraquinone-based repellent in California voles (Microtus californicus Peale), Richardson’s ground squirrels (Urocitellus richardsonii Sabine), deer mice (Peromyscus maniculatus Wagner) and cottontail rabbits (Sylvilagus audubonii Baird) in captivity. We observed 52–56% feeding repellency for whole oats treated with 10,800ppm anthraquinone or 18,500ppmanthraquinone in mice and squirrels, and 84–85% repellency for …

Multi-Isotopic (Δ2H, Δ13C, Δ15N) Tracing Of Molt Origin For Red-Winged Blackbirds Associated With Agro-Ecosystems, Scott J. Werner, Keith A. Hobson, Steven L. Van Wilgenburg, Justin W. Fischer

United States Department of Agriculture Wildlife Services: Staff Publications

We analyzed stable-hydrogen (δ²H), carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope ratios in feathers to better understand the molt origin and food habits of Red-winged Blackbirds (Agelaius phoeniceus) near sunflower production in the Upper Midwest and rice production in the Mid-South of the United States. Outer primary feathers were used from 661 after-second-year (ASY) male blackbirds collected in Minnesota, Montana, North Dakota and South Dakota (spring collection), and Arkansas, Louisiana, Mississippi, Missouri and Texas (winter collection). The best-fit model indicated that the combination of feather δ²H, δ¹³C and δ …

Immunotherapy Using Algal-Produced Ara H 1 Core Domain Suppresses Peanut Allergy In Mice, James A. Grgeory, Ariel Shepley-Mctaggart, Michelle Umpierrez, Barry K. Hurlburt, Soheila J. Maleki, Hugh A. Sampson, Stephen P. Mayfield, M. Cecilia Berin

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

Peanut allergy is an IgE-mediated adverse reaction to a subset of proteins found in peanuts. Immunotherapy aims to desensitize allergic patients through repeated and escalating exposures for several months to years using extracts or flours. The complex mix of proteins and variability between preparations complicates immunotherapy studies. Moreover, peanut immunotherapy is associated with frequent negative side effects and patients are often at risk of allergic reactions once immunotherapy is discontinued. Allergen-specific approaches using recombinant proteins are an attractive alternative because they allow more precise dosing and the opportunity to engineer proteins with improved safety profiles. We tested whether Ara h …

Component Greenhouse Gas Fluxes And Radiative Balance From Two Deltaic Marshes In Louisiana: Pairing Chamber Techniques And Eddy Covariance, Ken W. Krauss, Guerry O. Holm Jr., Brian C. Perez, David E. Mcwhorter, Nicole Cormier, Rebecca F. Moss, Darren J. Johnson, Scott C. Neubauer, Richard C. Raynie

United States Geological Survey: Staff Publications

Coastal marshes take up atmospheric CO₂ while emitting CO₂, CH₄, and N₂O. This ability to sequester carbon (C) is much greater for wetlands on a per area basis than from most ecosystems, facilitating scientific, political, and economic interest in their value as greenhouse gas sinks. However, the greenhouse gas balance of Gulf of Mexico wetlands is particularly understudied. We describe the net ecosystem exchange (NEE_c) of CO₂ and CH₄ using eddy covariance (EC) in comparison with fluxes of CO₂, CH₄, and N₂O using …

Interpreting And Predicting The Spread Of Invasive Wild Pigs, Nathan P. Snow, Marta A. Jarzyna, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

1. The eruption of invasive wild pigs (IWPs) Sus scrofa throughout the world exemplifies the need to understand the influences of exotic and nonnative species expansions. In particular, the continental USA is precariously threatened by a rapid expansion of IWPs, and a better understanding of the rate and process of spread can inform strategies that will limit the expansion.

2. We developed a spatially and temporally dynamic model to examine three decades (1982– 2012) of IWP expansion, and predict the spread of IWPs throughout the continental USA, relative to where IWPs previously inhabited. We used the model to predict where …

Urolithin A, C And D, But Not Iso-Urolithin A And Urolithin B, Attenuate Triglyceride Accumulation In Human Cultures Of Adipocytes And Hepatocytes, Inhae Kang, Yongeun Kim, Francisco A. Tomás-Barberán, Juan Carlos Espín, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Scope: Urolithins (Uro) are ellagic acid (EA)-derived metabolites produced by gut microbes. There is a growing interest in the biological activities of Uro. Our aim was to evaluate the impacts of Uro on regulating triglyceride (TG) accumulation using cultures of primary human adipocytes and hepatoma Huh7 cells.

Methods and Results: UroA, B, C, D, and iso-UroA, were used to determine the effect of Uro on adipogenesis and lipogenesis. Individual Uro (30 M) were added to human adipogenic stem cells (hASCs) during differentiation. UroA, C and D, but not iso-UroA and UroB, significantly inhibited new fat cell formation by decreasing TG …

Suppression Of Nlrp3 Inflammasome By Γ-Tocotrienol Ameliorates Type 2 Diabetes, Yongeun Kim, Wei Wang, Meshail Okla, Inhae Kang, Regis Moreau, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

The Nod-like receptor 3 (NLRP3) inflammasome is an intracellular sensor that sets off the innate immune system in response to microbial-derived and endogenous metabolic danger signals. We previously reported that γ-tocotrienol (γT3) attenuated adipose tissue inflammation and insulin resistance in diet-induced obesity, but the underlying mechanism remained elusive. Here, we investigated the effects of γT3 on NLRP3 inflammasome activation and attendant consequences on type 2 diabetes. γT3 repressed inflammasome activation, caspase-1 cleavage, and interleukin (IL) 1β secretion in murine macrophages, implicating the inhibition of NLRP3 inflammasome in the anti-inflammatory and antipyroptotic properties of γT3. Furthermore, supplementation of leptin-receptor KO mice …

Disparities In Access To Preventive Health Care Services Among Insured Children In A Cross Sectional Study, Christian King

Department of Nutrition and Health Sciences: Faculty Publications

Children with insurance have better access to care and health outcomes if their parents also have insurance. However, little is known about whether the type of parental insurance matters. This study attempts to determine whether the type of parental insurance affects the access to health care services of children. I used data from the 2009–2013 Medical Expenditure Panel Survey and estimated multivariate logistic regressions (N=26,152). I estimated how family insurance coverage affects the probability that children have a usual source of care, well-child visits in the past year, unmet medical and prescription needs, less than 1 dental visit per year, …
