Financial Health Of Grain Operations After Adding A Hog Barn, 2020 University of Nebraska - Lincoln
Financial Health Of Grain Operations After Adding A Hog Barn, Elliott James Dennis
Extension Farm and Ranch Management
There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replace commercial fertilizer expense as the primary reasons for adding a hog barn.
While there is industry demand to increase hog contract growing, these agreements can possess significant benefits and risks to producers. This is the second of a four part series which will discuss some financial and legal implications of adding a hog barn to ...
Identifying Fox Squirrels And Their Damage In Your Yard, 2020 Utah State University
Identifying Fox Squirrels And Their Damage In Your Yard, S. Nicole Frey, Jessica Tegt
All Current Publications
Native to the eastern United States, fox squirrels (Sciurus niger) were first documented in Utah in 2011. It is unknown how fox squirrels made their way into Utah; however, it is possible they followed riparian corridors (areas along rivers, where trees often grow) through Colorado into Utah and were only detected once their populations grew in number. Since the Utah Natural Heritage Program began tracking them, there have been over 500 observations of this species, predominantly around Salt Lake City and the Wasatch Front. Fox squirrels are the largest tree squirrel in the U.S. (17–28 inches, and 17 ...
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, 2020 Nova Southeastern University
To Feed Or Not To Feed: Examining The Effects Of Provisioning Tourism On Nurse Sharks In Caye Caulker, Belize, Carlee Jackson
All HCAS Student Capstones, Theses, and Dissertations
Wildlife tourism is increasing in popularity around the world, creating the need to understand alterations in animal behavior and spatial distributions that may occur due to associated anthropogenic disturbances. Nurse sharks (Ginglymostoma cirratum, Bonnaterre 1788) are commonly used for wildlife tourism within the Caye Caulker Marine Reserve in Belize. Shark and Ray Village (SRV) is a site within the reserve where nurse sharks are consistently fed by tour/snorkel boats to create an interactive experience with tourists, termed provisioning tourism. Prior to this experiment, no studies had been conducted in SRV to evaluate the impact of provisioning tourism (tourism that ...

Feral Swine, 2020 USDA National Wildlife Research Center
Feral Swine, Michael P. Glow, Nathan P. Snow, Kurt C. Vercauteren
Wildlife Damage Management Technical Series
Feral swine (Sus scrofa; Figure 1), also known as feral hogs, feral pigs, wild pigs, wild boar, or other similar derivations, are a non-native species considered to be one of the most destructive invasive terrestrial vertebrates in North America. While feral swine populations remained relatively small and confined in the continental United States following initial introductions by European explorers during the 15th century, substantial range expansion has occurred across every geographical region of the United States (Figure 2). This expansion has primarily been attributed to human-mediated movements, predominately for the purpose of establishing populations for recreational hunting, and facilitated by ...
Population Status, Threats, And Conservation Of Preuss's Red Colobus (Piliocolobus Preussi) And Other Diurnal Primates In The Ndokbou Forest, Littoral Region, Cameroon, Ruth Bowers-Sword
Masters Theses, 2020-current
The Ebo-Makombe-Ndokbou forest block in southwest Cameroon lies within the Gulf of Guinea biodiversity hotspot, characterized by extremely high levels of species richness and endemism, including those of primates. These forests may contain one of the last populations of the Critically Endangered Preuss’s red colobus monkey (Piliocolobus preussi; PRC), which is found only in southeastern Nigeria and western Cameroon. Gun hunting for bushmeat and habitat loss and degradation from logging and agriculture are the main threats to PRC. The conservation status of PRC and other primates in the Ndokbou forest are largely unknown, with most regional research efforts occurring ...

Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, 2020 University of Nebraska-Lincoln
Spatial Ecology And Resource Selection Of Bighorn Sheep (Ovis Canadensis) Ewes In A Prairie Badlands Population, Erin Wood
Dissertations & Theses in Natural Resources
The basic spatial ecology and habitat relationships of female bighorn sheep in Nebraska are poorly understood. Establishing seasonal patterns of space use and resource selection for this population at the margin of their historical and current range addresses a key knowledge gap and provides important baseline information for ongoing conservation efforts in Nebraska. We deployed GPS radio-collars on 56 adult ewes in western Nebraska to quantify seasonal space use, movements, and resource selection of ewes. To investigate spatial ecology, we quantified movements of ewes and the factors that influence home range size, seasonal use, and spatial stability across seasons. Home ...
Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, 2020 Chapman University
Wild Mice With Different Social Network Sizes Vary In Brain Gene Expression, Patricia C. Lopes, Barbara König
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Appropriate social interactions influence animal fitness by impacting several processes, such as mating, territory defense, and offspring care. Many studies shedding light on the neurobiological underpinnings of social behavior have focused on nonapeptides (vasopressin, oxytocin, and homologues) and on sexual or parent-offspring interactions. Furthermore, animals have been studied under artificial laboratory conditions, where the consequences of behavioral responses may not be as critical as when expressed under natural environments, therefore obscuring certain physiological responses. We used automated recording of social interactions of wild house mice outside of the breeding season to detect individuals at both tails of a distribution ...
Brain Complexity, Sentience And Welfare, 2020 University of Cambridge
Brain Complexity, Sentience And Welfare, Donald M. Broom
Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, 2020 University of South Dakota
Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt
The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with the genetic ...
The Role Of Dopamine In Decision Making Processes In Drosophila Melanogaster, 2020 University of San Diego
The Role Of Dopamine In Decision Making Processes In Drosophila Melanogaster, Michelle C. Bowers
Undergraduate Honors Theses
Understanding the neural processes that mediate decision making is a relatively new field of investigation in the scientific community. With the ultimate goal of understanding how humans decide between one path and another, simpler models such as Drosophila Melanogaster, the common fruit fly, are often utilized as a way of determining the neural circuits involved in these decision-making processes. One of the most important decisions flies make is the decision of where to lay their eggs (oviposit). Choosing the proper substrate upon which to lay eggs is a crucial decision that can ultimately impact their fecundity. This paper investigates the ...

Pilot Testing A Qualitative Methodology To Evaluate The Perceived Benefits And Stressors Of Sole-Dog Ownership In Full-Time College Students, Emma Williams
Animal Science Undergraduate Honors Theses
The number of individuals acquiring pets is continually increasing, with 71.5% of Americans owning a pet in 2012. Companion animals are a huge source of benefits but owning them can also come with several stressors. However, little research has been conducted on the negative aspects of dog ownership. This pilot test evaluates the perceived stressors and benefits of sole dog ownership in full-time college students. The pilot aimed to hold three focus groups from which qualitative thematic data were collected and quantitative were collected from a demographic survey of participants. Participants were asked a series of questions about sole ...
Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, 2020 University of Arkansas, Fayetteville
Use Of Diatomaceous Earth And Copper Oxide Wire Particles To Control Gastrointestinal Nematodes In Lambs, Olivia Jones
Animal Science Undergraduate Honors Theses
Anthelmintic resistance (AR) urges alternatives to control gastrointestinal nematodes (GIN). Copper oxide wire particles (COWP) are more efficacious when used with other dewormers and little is known on efficacy of diatomaceous earth (DE) to control gastrointestinal parasites. The objective was to examine the effects of DE and COWP on GIN control. Katahdin lambs (n = 32; ~150 d of age; 25.0 ± 1.8 kg) were randomly assigned to receive: 1) DE fed at an estimated 2% dry matter intake (with the assumption of moderate consumption of bermudagrass forage and provided supplement), 2) 1g COWP, 3) both 2% DE and ...

Usu Equine-Assisted Activities And Therapies Facilities Designed Master Plan, Lindsie C. Smith
All Graduate Plan B and other Reports
Equine-Assisted Activities and Therapies (EAAT) is recognized as a therapeutic approach for persons with disabilities. The USU Animal, Dairy, and Veterinary Sciences Department provides EAAT instruction and services; however, they do not have the appropriate facilities to model best-practices in the delivery of these services. This design research entailed the development of a phased masterplan to support the instruction and delivery of equine-assisted activities and therapies in an innovative and accessible environment that supports animal-assisted intervention and natural equine behaviors.
The methodology used to approach the master plan design was derived from Norman K. Booth’s (1990) design process, as ...
The Effects Of Phosphate On Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), 2020 University of Nebraska-Lincoln
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 ...
Chemosensory And Temperature-Based Prey Discrimination In Ball Pythons, 2020 Susquehanna University
Chemosensory And Temperature-Based Prey Discrimination In Ball Pythons, Brianne Yarger
Senior Scholars Day
Ball pythons (Python regius), like other snakes in the Boidae family, use heat-sensitive pit organs and odor-sensitive Jacobson’s organ (vomernasal organ) to detect prey. The discrimination sensitivity and interaction of these organs to influence prey detection and choice however have been poorly tested. We performed a series of two-choice experiments to determine ball python preference for specific odors and/or biologically-relevant thermal stimuli. We tested the following pairs of stimuli: 1) rat odor vs. water, 2) anterior vs posterior odors of a rat, 3) rat (familiar) vs rabbit (unfamiliar) odor, 4) rat vs orange peel odor, 5) odor from ...
Herbicide Effects On The Feeding Behavior Of The Wolf Spider Pardosa Milvina, 2020 Susquehanna University
Herbicide Effects On The Feeding Behavior Of The Wolf Spider Pardosa Milvina, Briana Heinly, William Ward, Catherine Johnson, Jack Preston
Senior Scholars Day
Herbicides can potentially impact feeding behavior of beneficial predators in agricultural systems and subsequently compromise integrated pest management efficacy. We measured variation in feeding behaviors of an agriculturally abundant wolf spider, Pardosa milvina, when exposed to soil with field-relevant concentrations of five commonly used herbicides. Tested herbicides included atrazine, S-metolachlor, rimsulfuron, mesotrione, glyphosate, a mixture of all five herbicides, and a distilled water control. Spiders were housed individually in containers with topsoil previously sprayed with a recommended herbicide dosage or water control. Tested spiders were collected from two adjacent fields: one kept under continuous crop rotation for over twenty years ...
