Use of toxic baits or other tools for managing nuisance species must ensure that the species of interest is adequately targeted while exposure to nontarget species is minimized. Nontarget takes of acetaminophen‐laced baits for control of invasive brown treesnakes (Boiga irregularis) on Guam may put those animals at risk of lethal intoxication and render the bait unavailable to the intended target species. We used wildlife cameras to identify species removing toxic and nontoxic baits from brown treesnake bait stations designed to exclude nontarget taxa in 2015 and 2016. Throughout various sites and habitat types, and balanced by season (wet ...


Time Allocation To Resources By Three Species Of Rats (Rattus Spp.) In A Radial Arm Maze, Gary Witmer, Nathan P. Snow, Rachael S. Moulton May 2020

Time Allocation To Resources By Three Species Of Rats (Rattus Spp.) In A Radial Arm Maze, Gary Witmer, Nathan P. Snow, Rachael S. Moulton

USDA National Wildlife Research Center - Staff Publications

Context. Introduced rats (Rattus spp.) can pose a serious threat to native flora and fauna, especially on islands where most species have evolved in the absence of terrestrial predators. Effective detection and eradication methods for introduced rats are essential to the maintenance of insular ecosystem integrity. Thus, it is important to better understand the behaviour of rats when they first arrive in a new setting.

Aims. To determine whether rats would find some novel stimuli to be significantly more attractive than other novel stimuli.

Methods. An eight-arm radial maze was used to study the behaviour of three species of Rattus ...


Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck May 2020

Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck

USDA National Wildlife Research Center - Staff Publications

Medium and large carnivores coexist with people in urban areas globally, occasionally resulting in

negative interactions that prompt questions about how to reduce human-wildlife conflict. Hazing,

i.e., scaring wildlife, is frequently promoted as an important non-lethal means for urbanites to reduce

conflict but there is limited scientific evidence for its efficacy. We used a population of captive coyotes (Canis latrans) to simulate urban human-coyote interactions and subsequent effects of hazing on coyote behavior. Past experiences with humans significantly affected the number of times a coyoteapproached a human to necessitate hazing. coyotes that had been hand fed by adults had ...

Deciphering Interactions Between White-Tailed Deer And Approaching Vehicle, Morgan Pfeiffer, Raymond B. Iglay, Thomas W. Seamans, Bradley F. Blackwell, Travis L. Devault

USDA National Wildlife Research Center - Staff Publications

Deer-vehicle collisions are a major transportation hazard, but factors affecting deer escape decision-making in response to vehicle approach remain poorly characterized. We made opportunistic observations of deer response to vehicle approach during daylight hours on a restricted- access facility in Ohio, USA (vehicle speeds were ≤64 km/h). We hypothesized that animal proximity to the road, group size, vehicle approach, and ambient conditions would affect perceived risk by white-tailed deer (Odocoileus virginianus) to vehicle approach, as measured by flight-initiation distance (FID). We constructed a priori models for FID, as well as road-crossing behavior. Deer responses were variable and did not ...

UCARE Research Products

Chapter 1

Mycobacterium avium complex (MAC) has become one of the major problems in public health and livestock. Members of MAC, such as M. avium subsp paratuberculosis (MAP) and M. avium subsp hominissuis (MAH), are responsible for many opportunistic infections and the loss of livestock. MAP is economically significant to the beef and dairy industries because it is the etiologic agent of Johnes’s disease, a chronic and fatal enteritis in ruminants. Tracing the infection sources of MAC could be difficult since it infects many types of hosts in the natural environment. Furthermore, there is less information known about MAP ...

Theses, Dissertations, and Student Research in Agronomy and Horticulture

With commercialization of multiple herbicide-resistant corn and soybean cultivars, producers have new management options for controlling herbicide-resistant weeds and volunteer corn. Corn-on-corn production systems are common in irrigated fields in southcentral Nebraska which can create issues with volunteer corn management in corn fields. Enlist corn contains a new multiple herbicide-resistant trait providing resistance to 2,4-D choline, glyphosate, and the aryloxyphenoxypropionate (FOPs). Field experiments were conducted in 2018 and 2019 at South Central Agricultural Laboratory near Clay Center, Nebraska with the objective to evaluate ACCase-inhibiting herbicides and herbicide application timing on volunteer corn control, Enlist corn injury, and yield. Glyphosate ...


Translational Genomics For Improving Sow Fertility, Hiruni R. Wijesena May 2020

Translational Genomics For Improving Sow Fertility, Hiruni R. Wijesena

Theses and Dissertations in Animal Science

Sow fertility traits, such as litter size and number of lifetime parities produced (reproductive longevity), are economically important. Selection for these traits is difficult because they are lowly heritable, polygenic, sex-limited, and express late in life. Age at puberty is an early indicator of reproductive longevity. Gilts that achieve puberty at an early age have a greater probability to produce more parities over their lifetime. However, measuring age at puberty is time consuming and tedious. Identifying pleiotropic polymorphisms that affect age at puberty and other fertility traits, including reproductive longevity, could help to improve the accuracy of genomic prediction for ...

Energy And Amino Acid Metabolism In Lactating Jersey Cows Consuming Feed Byproducts, Kyle Mclain

Theses and Dissertations in Animal Science

Animal protein byproducts are high bypass proteins commonly used in the dairy industry. These bypass proteins can escape the rumen to supply additional amino acids needed to support milk and protein yield. Two of the more popular animal protein byproducts used in the dairy industry are blood meal and hydrolyzed feather meal. In the first experiment, two flow meters were compared using headbox-style calorimeters. The objectives of the first study were to test mass flow meter (MFM) and volumetric flow meter (VFM) by measuring O2 consumption and CO2 production and to illustrate the effects of incomplete gas recovery on estimated ...


The Impact Of Oxidative Stress On Postmortem Meat Quality, Nicolas J. Herrera May 2020

The Impact Of Oxidative Stress On Postmortem Meat Quality, Nicolas J. Herrera

Theses and Dissertations in Animal Science

Tenderness is the primary factor to influence consumer palatability in fresh meat. The tenderization of muscle is dependent on proteolytic mechanisms, including calcium dependent, non-lysosomal endogenous enzymes such as calpains and proteasomes. These mechanisms have been indicated alongside apoptosis early postmortem as cascades of apoptotic events promote ideal conditions for postmortem tenderization. Recent literature has identified oxidative stress-mediated events to be linked to apoptotic activity. Oxidative stress is defined as the overwhelming production of reactive species compared to homeostatic, endogenous antioxidants present within muscle systems. These conditions exhaust antioxidant function and facilitate reactive species to alter protein, lipid, or nucleic ...

Protein Availability And Consumption, And Stunting Rates, For Primary School Children In The Southern Regions Of Ethiopia And Zambia, Megan Wackel May 2020

Protein Availability And Consumption, And Stunting Rates, For Primary School Children In The Southern Regions Of Ethiopia And Zambia, Megan Wackel

NUTR/GLST 498b: Global Research Experiences in Nutrition & Health

•Stunting is common in Sub-Sahara Africa, with millions of children who are short in stature also experiencing poor overall health and development, as well as poor school performance (Semba 2016; Semba, et al., 2016). •As many as 39% of children under 5 years of age in Ethiopia’s Sidama Region (formerly SNNPR) can be classified as stunted (CSA & ICF 2016). By comparison, 29% of under 5’s in Zambia’s Southern Province have short height for age (CSA, MOH, & ICF 2018). •Low protein and essential amino acid intake, among populations of 116 countries, has been suggested as the primary cause of stunting (Semba 2016; Semba, et al., 2016). •Given that Ethiopia and Zambia have high rates of stunting, children are unlikely to be consuming protein on a regular basis. Because data on protein availability and dietary intake are limited, this study was designed to explore availability ...


The Effects Of Phosphate On Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Lexy Polivanov, Dennis Ferraro Apr 2020

The Effects Of Phosphate On Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Lexy Polivanov, Dennis Ferraro

UCARE Research Products

This study seeks examine the effects of elevated phosphate levels on the larval stage of the Western Barred Tiger Salamander (Ambystoma mavortium). Hypothesis: Additional phosphate in the water will cause the larval salamanders to have a slower metamorphosis rate than the control group with no additional phosphates. This hypothesis is based off of research that showed that additional nitrogen in the water caused a slower growth rate in the Western Barred Tiger Salamander (Ambystoma mavortium) (Griffis-Kyle, 2007).

The hypothesis was rejected. The dates the larvae morphed alternated between treatment and control. The treatment metamorphosis was not slowed. Temperature was found ...

UCARE Research Products

It is now well established that the composition of the gastrointestinal (GI) microbiota has a profound influence on intestinal and overall health. Many contemporary diseases such as type two diabetes, IBS and obesity are associated with a dysbiotic microbiota. Therefore, researchers are interested in how diet and specific dietary components can modulate the gastrointestinal microbiota and possibly repair a dysbiotic state. One approach to improve gastrointestinal health is by consuming probiotics and prebiotics or a diet rich in fermented foods containing live microbes. Fermented foods are popular because of their enhanced preservation, safety, organoleptic, functionality, and nutritional properties. These fermented ...

Fungicide Sensitivity Of Sclerotinia Sclerotiorum Isolates From Five States With Different Fungicide Treatments, Cristian Wulkop Gil, Edgar Nieto-Lopez, Sydney Everhart

UCARE Research Products

Sclerotinia sclerotiorum is a plant pathogenic fungus that causes a disease called white mold that can infect more than 450 plant species including soybeans, dry beans, green beans, canola, and sunflower. This pathogen is capable of up to $252M in losses every year (U.S. Canola Association, 2014). Fungicides are widely used in developed agricultural systems to control disease. However, resistance to the most effective fungicides has emerged and spread in pathogen populations and there have been multiple reports of S. sclerotiorum isolates becoming resistant to certain fungicides. Since different fields in different states use different fungicide treatments on plants ...


Zika Virus Induces Apoptosis In Retinal Pigmented Epithelial Cells, Madison Kraus, Philma Glora Muthuraj, Sathish Kumar Natarajan Apr 2020

Zika Virus Induces Apoptosis In Retinal Pigmented Epithelial Cells, Madison Kraus, Philma Glora Muthuraj, Sathish Kumar Natarajan

UCARE Research Products

Zika virus is a single-stranded positive sense RNA virus that attracted international attention in 2015 when an epidemic broke out in Brazil. This vector borne virus is transmitted by mosquitos and is especially concerning for pregnant women because the virus can affect the development of the fetus. One known complication is the destruction of infected retinal epithelial cells. The transduction of light is interrupted due to cell death and results in blind spots. Previous research has demonstrated that palmitoleate can reduce the observed levels of apoptosis in ZIKAV infected JEG-3 cells. We have also seen the protection of retinal pigmented ...


Evolutionary And Ecological Determinism Of Host Specificity In Arthropod Parasites, Joseph Levey Apr 2020

Evolutionary And Ecological Determinism Of Host Specificity In Arthropod Parasites, Joseph Levey

UCARE Research Products

Understanding why some diseases infect more species than others is crucial for predicting where and when disease will spread, which can inform the management of wildlife, agriculture, and human health. Currently, large scale patterns of host-parasite dynamics are being studied to understand where to look for and how to manage emerging human diseases (Leroy 2005; Benelli 2018). Previous research has used the Global Mammal Parasite Database (GMPD) to look at host breadth—the number and diversity of species a pathogen can infect—for various groups of parasites, e.g. helminths, arthropods, fungi, etc., from a host-centric perspective (Stephens et al ...

Mutagenesis Of Claudins To Probe In Vivo Interactions And Assemblies, Currey Zalman, Alex J. Vecchio

UCARE Research Products

Paracellular transport of solutes and the control of the flow of molecules through the intracellular space in vertebrate epithelia is directed by tight junctions (TJs). Claudins form paracellular barriers and pores that determine tight junction permeability. This investigation attempts to explain the molecular bases for destruction and reconstruction of tight junctions within epithelial cells, occurring via both natural and disease-causing mechanisms. This interdisciplinary research is important in the advancement of our understanding of human biology and health, as different disruptions to epithelial tight junctions are hallmarks of many human diseases. The overall objective was to take previously made Claudin containing ...
