Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo 2018 University of New England

Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Noah G. Perlut, Patricia G. Parker, Rosalind B. Renfrew, Maricruz Jaramillo

Environmental Studies Faculty Publications

Bobolinks (Dolichonyx oryzivorus) migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four Plasmodium lineages recently detected in resident Galapagos birds. We hypothesized that Bobolinks carried these parasites to Galapagos, where they were bitten by mosquitoes that then transmitted the parasites to resident birds. The haemosporidian parasite community in 44% of the Bobolinks we captured was consistent with those on their breeding grounds ...


Phenotypic Association Between Lactose And Other Milk Components In Western Us Dairy Herds And Japan, Takuji Asami 2018 Utah State University

Phenotypic Association Between Lactose And Other Milk Components In Western Us Dairy Herds And Japan, Takuji Asami

All Graduate Theses and Dissertations

Lactose in milk has relatively low variation regardless of season, breed, or country. The study of lactose concentration and correlation among other milk components is limited. Furthermore, dairy farmers have limited access to the lactose data and are not familiar with it. This study was conducted to: 1) investigate the phenotypic correlation between lactose and other milk components; and 2) determine the importance of lactose for dairy herds.

Monthly DHIA records from Utah (DHIA), Dairy Herd Performance Test (DHTP) records from Ibaraki, Japan, and California herd average data (CHAD) covering 27 states were used to analyze the relationships between milk ...

A New Species Of Vaejovis From The Patagonia Mountains, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey

Euscorpius

A new scorpion species, Vaejovis patagonia sp. nov. is described and placed in the “vorhiesi” group. This small, dark brown species is found near Patagonia, Arizona. It is geographically closest to V. troupi Ayrey & Soleglad, V. grahami Ayrey & Soleglad and V. vorhiesi Stahnke. Those three species are found in a triangle surrounding the Patagonia Mountains, the locality of Vaejovis patagonia. The pedipalp fixed finger has 5 ID denticles and the movable finger has 6, like most, but not all, of the other southern Arizona Vaejovis. Carapace of female is shorter than metasomal segment V.

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 ...


Effects Of Dietary Zinc Concentration During Gestation On Preweaning Progeny Performance, Melanie Whitmore 2018 University of Wyoming

Effects Of Dietary Zinc Concentration During Gestation On Preweaning Progeny Performance, Melanie Whitmore

Honors Theses AY 17/18

Mastitis is one of the leading reasons for culling ewes from U.S. flocks, and subclinical mastitis indicated by high somatic cell counts (SCC) in milk has also been shown to negatively impact ewe productivity. However, means to reduce subclinical mastitis and consequential effects on lamb production are sparse. A previous study which found deprived zinc levels in ewes with high SCC suggests that ewes supplemented with zinc may exhibit lower SCC and increased lamb performance (Murphy et al, 2018). In this study, yearling ewes (n = 59) were provided zinc above dietary recommendations during gestation and the effects on lamb ...

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon 2018 The University of San Francisco

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon

Master's Theses

This thesis analyzes the international discourse of greenhouse gas emissions in relation to livestock production. Specific government ministries, research institutes, and multilateral organizations are framing a new strategy to mitigate emissions by using emissions intensity metrics. Emissions intensity is a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence of this metric in international discourse and the implications this shift has on the livestock sector globally. Ultimately ...


The Impact Of Parental Traits, Offspring Traits, And Climate On Parental Care During The Incubation Stage In A Tropical Bird, Sarah Brannon, Corey Tarwater 2018 University of Wyoming

The Impact Of Parental Traits, Offspring Traits, And Climate On Parental Care During The Incubation Stage In A Tropical Bird, Sarah Brannon, Corey Tarwater

Honors Theses AY 17/18

Many factors could play a role in individual variation in amount and length of parental care. We studied parental care during the incubation period of the Black-capped antshrikes (Thamnophilus atrinucha) in central Panama. Our comprehensive data set allowed us to determine the impacts of parental traits (age and sex), offspring traits (time of year and age of young), and climate (rain and temperature) on variation in parental care within the species. We found that an interaction between sex and age of the adult influenced incubation behavior, while time of the year and age of young did not alter incubation. Perhaps ...

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 ...


Potential Minimum Threshold For Pallid Sturgeon Relative Condition In The Lower Missouri River, Kirk D. Steffensen 2018 Nebraska Game and Parks Commission

Potential Minimum Threshold For Pallid Sturgeon Relative Condition In The Lower Missouri River, Kirk D. Steffensen

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Pallid Sturgeon (Scaphirhynchus albus) condition has declined in the lower Missouri River but the cause and the effects of this decline remain uncertain. Adult Pallid Sturgeon are becoming reproductively ready less frequently and sub-adult Pallid Sturgeon are likely delaying sexual maturation. Even more concerning, Pallid Sturgeon capture rates have declined the past two years (i.e., 2016 and 2017), despite the ongoing Pallid Sturgeon stocking program. Several Pallid Sturgeon that have been captured are visually emaciated but a minimum condition threshold has not been described. Therefore, the aim of this study is to present a potential lethal condition level for ...

Animal, Dairy, and Veterinary Science Faculty Publications

The accumulating evidence demonstrates that Syrian hamsters have advantages as models for various diseases. To develop a Syrian hamster (Mesocricetus auratus) model of human immunodeficiency caused by RAG1 gene mutations, we employed the CRISPR/Cas9 system and introduced an 86-nucleotide frameshift deletion in the hamster RAG1 gene encoding part of the N-terminal non-core domain of RAG1. Histological and immunohistochemical analyses demonstrated that these hamsters (referred herein as RAG1-86nt hamsters) had atrophic spleen and thymus, and developed significantly less white pulp and were almost completely devoid of splenic lymphoid follicles. The RAG1-nt86 hamsters had barely detectable CD3+ and CD4+ T cells ...


Evaluation Of Alpha Amylase Containing Corn On Finishing Cattle Performance And Digestibilty, Melissa L. Jolly-Breithaupt 2018 University of Nebraska Lincoln

Evaluation Of Alpha Amylase Containing Corn On Finishing Cattle Performance And Digestibilty, Melissa L. Jolly-Breithaupt

Theses and Dissertations in Animal Science

One digestion and four finishing trials were conducted to evaluate the effect of a new corn hybrid containing an α-amylase trait, Syngenta Enogen Feed Corn (SYT-EFC) on site and extent of digestion, ruminal fermentation parameters, and feedlot performance. Experiments utilized corn containing the enzymatic gene compared to controls, the near isoline parental corn (NEG) or commercially available corn grain (CON), processed as dry-rolled corn (DRC) or high moisture corn (HMC) in diets with dry [distillers grains plus solubles (DGS)] or wet (Sweet Bran) milling byproducts. The corn grain of the experimental diets were fed as the sole grain source, comprising ...


Targeted-Grazing As A Fuels Reduction Treatment: Evaluation Of Vegetation Dynamics And Utilization Levels, Travis Decker 2018 Utah State University

Targeted-Grazing As A Fuels Reduction Treatment: Evaluation Of Vegetation Dynamics And Utilization Levels, Travis Decker

All Graduate Theses and Dissertations

Wildfires have caused concern as they have increased in severity and intensity over the last few decades. Land managers have sought management actions to mitigate the risk of wildfire by reducing fuel loads, thus decreasing wildfire intensity. Camp Williams is a National Guard camp near Bluffdale, Utah, where small arms and artillery training occurs. Managers at Camp Williams have created fuel breaks by implementing targeted sheep and goat grazing to remove fine fuel and thin brush. Management objectives set utilization of fine fuels (herbaceous) at 80% by weight. Questions arose regarding the ecological impact of the prescribed grazing rates in ...

Veterinary Training Practice In Pinnipeds, Samantha Hatfield 2018 University of Rhode Island

Veterinary Training Practice In Pinnipeds, Samantha Hatfield

Senior Honors Projects

Little research has been conducted in determining how to train a Northern Fur Sea Lion (Callorhinus ursinus) for veterinary husbandry care procedures. There is no clear path or instruction manual on how to complete a veterinary examination on a Fur Sea Lion, or any marine mammal for that matter, since every animal behaves and reacts differently. Animal behavior (ethology) is an ongoing field of study that focuses on the natural interactions between these species with each other, other living organisms (including humans), and their environment. The purpose of this research is to establish a guideline on how to begin training ...


Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth DeLay 2018 University of Arkansas, Fayetteville

Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth Delay

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Foreign Direct Investment (FDI) has the potential to increase economic activity and improve GDP growth in low-income countries, but can hinder economic development (quality of life improvements) if not sustainable and holistic in manner. Africa serves as a host to many cases of FDI focused on economic growth, but not necessarily improving the quality of life for its citizens. FDI has spread throughout the African continent, where many countries are well endowed with natural resources, like minerals and coal. These economies have experienced rapid GDP growth with few benefits reaching citizens of the host country. Mozambique is a low-income country ...


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 ...
