Investigation Of Zebrafish Larvae Behavior As Precursor For Suborbital Flights: Feasibility Study, Pedro Llanos, Kristina Andrijauskaite, Mark Rubinstein, Sherine S.L. Chan 2018 Embry-Riddle Aeronautical University - Daytona Beach

Investigation Of Zebrafish Larvae Behavior As Precursor For Suborbital Flights: Feasibility Study, Pedro Llanos, Kristina Andrijauskaite, Mark Rubinstein, Sherine S.L. Chan

Pedro J. Llanos (www.AstronauticsLlanos.com)


Suborbital spaceflights, carrying scientific payloads, allow scientists not only to test the feasibility of their payloads, but they also provide the basis for refining scientific hypotheses to be later tested on the International Space Station (ISS). Therefore, it is essential to establish robust pre-flight procedures in order to take advantage of this unique research platform to facilitate payload delivery. In the present study, we assessed zebrafish larvae behavior as a precursor for the future suborbital spaceflight involving research on the musculoskeletal system. Zebrafish larvae were exposed to the same physiological stressors they would encounter during suborbital spaceflight: alterations in light ...


Sniffer Dogs, Kayla Holland 2018 University of Mississippi

Sniffer Dogs, Kayla Holland

International Journal of Security Studies

Sniffer dogs have worked alongside law enforcement officers, military units, border patrols and search and rescue teamss since the 1980s. There are two training locations for canines. One is located in Front Royal, Virginia. The headquarters of the Customs and Border Protection Canine Training center is located in El Paso, Texas. There has been many different studies conducted on sniffer dogs and their ability to detect certain odors. One of those studies was conducted by Osterkamp (2011) who examined how dogs are capable of transporting particular scents in water into their noses. Water dogs have been used in the U ...


Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King 2018 Wildlife Control Consultant, LLC Lewistown, Montana

Wildlife Carcass Disposal, Stephen M. Vantassel, Mark A. King

Wildlife Damage Management Technical Series

Many wildlife management situations require the disposal of animal carcasses. These can include the lethal removal of wildlife to resolve damage or conflicts, as well as clean-up after mortalities caused by vehicle collisions, disease, oil spills (Figure 1) or other natural disasters. Carcasses must be disposed of properly to protect public sensitivities, the environment, and public health. Improper disposal of carcasses can result in public outrage, site contamination, injury to animals and people, and the attraction of other animals that may lead to wildlife damage issues. Concern over ground water contamination and disease transmission from improper carcass disposal has resulted ...


Wildlife Translocation, Michael T. Mengak 2018 University of Georgia

Wildlife Translocation, Michael T. Mengak

Wildlife Damage Management Technical Series

Many people enjoy wildlife. It enriches their lives in many ways. Nationwide, Americans spend over $144 billion annually on fishing, hunting, and wildlife-watching activities. However, wildlife is not always welcome in or near homes, buildings, or other property and can cause significant damage or health and safety issues (Figure 1). In one study, 42% of urban residents reported experiencing a wildlife problem during the previous year and more than half of them said their attempts to resolve the problem were unsuccessful. Many people who experience a wildlife conflict prefer to resolve the issue without harming the offending animal. Of the ...


Evaluation Of Dopaminergic And Antidopaminergic Agents For Use In Equine Metabolic Physiology, Nicole Arana Valencia 2018 Louisiana State University and Agricultural and Mechanical College

Evaluation Of Dopaminergic And Antidopaminergic Agents For Use In Equine Metabolic Physiology, Nicole Arana Valencia

LSU Doctoral Dissertations

A series of experiments studied the effects and practical applications of dopaminergic and antidopaminergic compounds in equine metabolic physiology. The first experiment was performed to assess the long-term effects of repeated cabergoline injections (every 10 days for a total of seven injections) on prolactin and α-melanocyte stimulating hormone concentrations in insulin insensitive mares. Additionally, the experiment also evaluated the use of cabergoline for improving insulin sensitivity. Plasma prolactin and α-melanocyte stimulating hormone concentrations were suppressed throughout the duration of the experiment even when the mares were challenged with a low-dose dopamine antagonist, sulpiride, the day previous to their subsequent cabergoline ...


Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke 2018 Chapman University

Common Loons Respond Adaptively To A Black Fly That Reduces Nesting Success, Walter H. Piper, Keren B. Tischler, Andrew Reinke

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Nesting birds must often cope with harassment from biting insects, but it is difficult to ascertain what effect such pests might have on breeding success and population dynamics. We tested the hypothesis that a black fly (Simulium annulus) that feeds on the blood of nesting Common Loons (Gavia immer) causes nest abandonment in this charismatic diving bird. In addition, we measured effects of fly-induced abandonment on a loon population, and examined potential predictors of fly abundance and nest abandonment. We also tested a second hypothesis, which holds that loon pairs that abandon a nest owing to flies should often remain ...


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender 2018 Fordham University

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...


Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes 2018 University of Maine

Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes

Electronic Theses and Dissertations

Bacterial uterine infections inflict major losses on the equine breeding industry. These infections usually arise from bacteria introduced at breeding. Micro-currents propelled by ciliated cells between the folds of the uterus and cervix have been proposed as a means by which contaminants are expelled. Previous data have shown possible ciliary micro-currents propelling carbon particles, occasionally rotating, through cervical folds. However, adherence to the epithelium may have interfered with movement of carbon in these studies. Therefore, we tested potentially non-adherent substances to reveal ciliary micro-currents on the equine cervix under high magnification video-endoscopy. We hypothesized that polyethylene green microspheres 1 - 5 ...


Morphological Traits As Indicators Of Sexual Dimorphism In Prairie Rattlesnakes (Crotalus Viridis), Colleen Rothe-Groleau, Claudia M. Rauter, James D. Fawcett 2018 University of Nebraska at Omaha

Morphological Traits As Indicators Of Sexual Dimorphism In Prairie Rattlesnakes (Crotalus Viridis), Colleen Rothe-Groleau, Claudia M. Rauter, James D. Fawcett

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

As humans encroach into areas inhabited by predators, the potential of human-predator confrontations increases and the predators become regarded as dangerous pests. Predators exert a measure of population control over pest species such as small rodents, as well as limit the quantity and scope of diseases (e.g. spread of Hantavirus by these prey species). Control of these small rodent pest species can be aided by conserving and managing their predators like rattlesnakes (Crotalus spp). Management of any population requires detailed information on population composition and the ability to determine the key information (especially age and sex) for each individual ...


Biological And Abiotic Factors Influencing Cetacean Mass Strandings In The Northeastern United States, Octavia Williams 2018 Nova Southeastern University

Biological And Abiotic Factors Influencing Cetacean Mass Strandings In The Northeastern United States, Octavia Williams

HCNSO Student Capstones

Marine mammal strandings are frequent occurrences along many coastal areas around the world. The significance of stranded cetaceans has been of interest since around 300 B.C. when philosophers, like Aristotle, pondered why marine mammals, including whales, dolphins and porpoise beach themselves; and famous authors, like Henry David Thoreau, whose fascination in mammal strandings lead him to write a book about these mass occurrences off the coast of Cape Cod. Numerous hypothetical theories have been developed to explain these mass stranding phenomena. Though the causes of mass strandings remain unresolved, recent investigations suggest contributing factors could include environmental elements. Less ...


Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter 2018 University of Arkansas, Fayetteville

Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter

Animal Science Undergraduate Honors Theses

A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Further growth performance data were analyzed during different phases of the nursery stage. Overall, no effect of teat order was found on average daily gain, average ...


Relationships Among Beef Cow Productivity Traits And Single Nucleotide Polymorphisms In The Bovine Heat Shock Protein 70 Gene, Ashley Finney 2018 University of Arkansas, Fayetteville

Relationships Among Beef Cow Productivity Traits And Single Nucleotide Polymorphisms In The Bovine Heat Shock Protein 70 Gene, Ashley Finney

Animal Science Undergraduate Honors Theses

When eukaryotes are exposed to stressors such as heat, toxins, and low oxygen levels, heat shock proteins (HSPs) are synthesized to maintain normal cellular function within the body. Single nucleotide polymorphisms in the heat shock protein 70 (Hsp70) gene have been associated with calving percentage, and Julian calving date in spring-calving crossbred Brahman cows (Rosenkrans, et al., 2010). Our objective was to determine associations between previously identified polymorphisms in the promoter region and coding sequence of the bovine Hsp70 gene and beef cow efficiency. We evaluated productivity traits, including Julian calving date and calving rates, of fall-calving cows at each ...


Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans 2018 USDA, Wildlife Services

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans

Wildlife Damage Management Technical Series

Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to ...


How Wolves Turned Into Dogs And How Dogs Are Valuable In Meeting Human Social Needs, Kurt Kotrschal 2018 University of Vienna Department of Behavioural Biology, Wolf Science Center and University of Veterinary Medicine Vienna

How Wolves Turned Into Dogs And How Dogs Are Valuable In Meeting Human Social Needs, Kurt Kotrschal

People and Animals: The International Journal of Research and Practice

A wealth of recent behavioral, neurobiological, and genetic results allows us to draw a new, comprehensive picture of the human-wolf- dog relationship. Dogs originated from wolves 35,000 years ago, mainly via selection for tameness. Wolves were probably spiritual partners and hunting buddies of Paleolithic hunter-gatherers over wide areas of Eurasia. Coming together and staying together was probably facilitated by the close ecological and social match between wolves and humans. Both are cursorial hunters and scavengers living in cooperative but relatively closed family groups, which selected for very similar mentalities.

Parallel selection for tameness (i.e., being “nice”) in dogs ...


Keeping And Killing: Six Conversations On The Complex Nature Of The Human-Animal Relationship, Shannen Cashman 2018 Lake Forest College

Keeping And Killing: Six Conversations On The Complex Nature Of The Human-Animal Relationship, Shannen Cashman

Senior Theses

This thesis examines the complexity of animal-human relationships in the contemporary United States, drawing on literature, science, and philosophy to explore the various ways that humans keep animals in captivity, such as in the instances of pet-keeping, animal research, and animal agriculture, while also having to kill them. By examining these ways of interacting with animals, an inherent duality within human consciousness is exposed. Humans both do and do not want to take responsibility for their actions regarding animals, often times resulting in humans telling themselves stories that make them feel more comfortable with these conflicting desires. The final chapter ...


Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins 2018 Lynchburg College

Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins

Student Scholar Showcase

Global agriculture is beset by numerous challenges which must be surmounted to feed a developing world, from combating climate change to the cultivation of sustainable food products. This, in addition to protein and nutrient deficiencies in the developing world, makes considering alternative protein sources, such as a crickets, an attractive option. Crickets use a fraction of the land and water that protein sources like beef cattle do, and can be cultivated in urban environments in stacked boxes. This research investigation aims to quantify the nutrient mineral content (Iron, Sodium, Potassium, Calcium, and Magnesium) of two cricket species (Acheta domesticus & Gryllodes ...


Uvb Avoidance In Dendrobates Azereus Tadpoles, Matthew Sturtevant, Lee Kats, Agustin Vargas, Arthur Garnica 2018 Pepperdine University

Uvb Avoidance In Dendrobates Azereus Tadpoles, Matthew Sturtevant, Lee Kats, Agustin Vargas, Arthur Garnica

Seaver College Research And Scholarly Achievement Symposium

Most frogs are nocturnal, but dart frogs (Dendrobatidae) are diurnal and lack scales or hair that would protect them from UVB rays. Previous studies have demonstrated that adult dart frogs avoid UVB light. The purpose of this experiment was to test whether dart frog larvae would avoid UVB light when compared to local nocturnal treefrog larvae. For the experiment we used tadpoles of Dendrobates azureus and Pseudacris regilla. The tadpoles were put in tubs with a submerged shelter and exposed to 3 lighting conditions: UVB, no light and visible light. The tadpoles were exposed to only one lighting condition each ...


An Analysis Of The Characteristics And Practices Of Selected Florida Small Livestock Producers: A Focus On Production And Processing, Jannette R. Bartlett, David Nii O. Tackie, Dana Reid, Akua Adu-Gyamfi, Angela McKenzie-Jakes 2018 Tuskegee University

An Analysis Of The Characteristics And Practices Of Selected Florida Small Livestock Producers: A Focus On Production And Processing, Jannette R. Bartlett, David Nii O. Tackie, Dana Reid, Akua Adu-Gyamfi, Angela Mckenzie-Jakes

Professional Agricultural Workers Journal

The study assessed the characteristics and practices of small livestock producers, emphasizing production and processing. Data were obtained from a convenience sample of seventy small producers from selected counties in Florida, and analyzed using descriptive statistics, including chi-square tests. The socioeconomic characteristics showed that part-time producers, White producers, middle-aged producers, fairly educated producers, and moderate-income producers dominated the group. A majority of the producers practiced rotational grazing, fed a combination of forage and concentrate, and less than half conducted soil tests regularly. Moreover, over half had parasite problems and treated them primarily with anthelmintics. Nearly all producers sold animals live ...

Bats Of Sint Eustatius, Caribbean Netherlands, Scott C. Pedersen, Peter A. Larsen, Sil A. Westra, Ellen Van Norren, Wesley Overman, Gary G. Kwiecinski, Hugh H. Genoways

Mammalogy Papers: University of Nebraska State Museum

The bat fauna of the Caribbean island of Sint Eustatius consists of five documented species—Monophyllus plethodon, Brachyphylla cavernarum, Artibeus jamaicensis, Ardops nichollsi, and Molossus molossus—and one provisional species—Tadarida brasiliensis. The Insular Single-leaf Bat, M. plethodon, is reported in the scientific literature for the first time from Sint Eustatius based on material presented herein. The bat fauna of the island is considered to be unbalanced because only three species, which are the environmental generalists, are abundant, whereas the more specialized species are rare or absent from the fauna. It is our hypothesis that the unbalanced bat fauna on ...


Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz 2018 University of Nebraska at Omaha

Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, Jonathan Korbitz

Student Research and Creative Activity Fair

Abstract:

The northern long-eared bat (Myotis septentrionalis) is one of many species of hibernating bats in North America affected by a recently discovered fungal disease called white-nose syndrome (WNS). Northern long-eared bats seem to be extremely susceptible to the disease with mass fatalities occurring among populations in eastern North America. Researchers in the eastern distribution of this species have performed mtDNA analysis to identify the population structure of the species; however, genetic analysis has yet to be done in western parts of its distribution. The goal of this study is to create a better understanding of the genetic makeup of ...
