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

Bovine Mastitis Resistance: Novel Quantitative Trait Loci And The Role Of Bovine Mammary Epithelial Cells, 2018 Utah State University
Bovine Mastitis Resistance: Novel Quantitative Trait Loci And The Role Of Bovine Mammary Epithelial Cells, Jacqueline P. Kurz
All Graduate Theses and Dissertations
Bovine mastitis, or inflammation of the mammary gland, has substantial economic and animal welfare implications. A genetic basis for mastitis resistance traits is recognized and can be used to guide selective breeding programs. The discovery of regions of the genome associated with mastitis resistance, and knowledge of the underlying molecular mechanisms responsible, can facilitate development of efficient mastitis control and therapeutic strategies. The objectives of this dissertation research were to identify sites of genetic variation associated with mastitis resistance, and to define the contributions of the milk-secreting epithelial cells to mammary gland immune responses and mastitis resistance. Twenty seven regions ...
Uvb Avoidance In Dendrobates Azereus Tadpoles, 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 ...
Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, 2018 Boise State University
Climate Change, Cattle, And The Challenge Of Sustainability In A Telecoupled System In Africa, Tara S. Easter, Alexander K. Killion, Neil H. Carter
Neil Henderson Carter
Information, energy, and materials are flowing over greater distances than in the past, changing the structure and feedbacks within and across coupled human and natural systems worldwide. The telecoupling framework was recently developed to understand the feedbacks and multidirectional flows characterizing social and environmental interactions between distant systems. We extend the application of the telecoupling framework to illustrate how flows in beef affect and are affected by social-ecological processes occurring between distant systems in Africa, and how those dynamics will likely change over the next few decades because of climate-induced shifts in a major bovine disease, trypanosomosis. The disease is ...
Investigating The Genetic Structure Of Northern Long-Eared Bats In Nebraska, 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
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 ...

When Extinction Is More Ethical Than Conservation: The Endangered Species Act And The Keystone Dilemma, 2018 Danville Community College
When Extinction Is More Ethical Than Conservation: The Endangered Species Act And The Keystone Dilemma, Miranda F. Thomas
This paper examines how the Endangered Species Act's measures to protect endangered species have resulted in increased rates of extinction. The author summarizes the concept of endangered keystone species and explains the processes and operations of the environmental legislation enacted to protect the species. The paper discusses the harmful consequences that certain laws have had on both species and humans, such as misappropriating resources to species that are not as endangered as others, and abusing regulations in manners that punish people for conservation efforts. By examining opposing arguments that favor increased regulation, this paper explains through data from leading ...
Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, 2018 Germanna Community College
Hunting A Home: The Abandonment And Neglect Of Hunting Dogs, Jamie B. Walker
Each year, an immeasurable number of hunting dogs are found in emaciated, malnourished or even abusive conditions due to neglect and abandonment by their owners. These dogs, primarily hounds, have increasingly become a burden on animal shelters and have cast a negative light on hunting with dogs, particularly in Virginia. The difficulty in identifying the owners of these dogs has stymied law enforcement and animal welfare authorities for years. Mandatory microchipping, now compulsory in England, may be the key to protecting talented working dogs from neglect, cruelty and abandonment by uncaring owners. These microchips can allow abandoned animals to lead ...
The Controversy Of Sunscreen Ingredients: Examining The Relationship Between Oxybenzone And Butylparaben On Stylophorum Pistillata, 2018 Northern Virginia Community College, Annandale Campus
The Controversy Of Sunscreen Ingredients: Examining The Relationship Between Oxybenzone And Butylparaben On Stylophorum Pistillata, Brian K. Lee, Natalia Corvalan, Jae Z. Saraum
The basis of this proposal is to understand the relationship between select UV filters and coral bleaching and provide a framework for additional research. Coral reefs are home to a diversity of marine life and are keystones to major coastal economies around the world. Oxybenzone and butylparaben are major ingredients found in sunscreen that induces coral bleaching to major coral reefs. To alleviate the negative effects, this proposal will attempt to better understand how oxybenzone and butylparaben facilitates coral bleaching and develop an effective and environmentally fair sunscreen. The research proposed will be funded by donors to cover research ...

The Great Lakes Entomologist
A study of fecal samples collected over a two-year period from juvenile ornate box turtles (Terrapene ornata ornata Agassiz) revealed diets consisting of six orders of insects representing 19 families. Turtles were reared in captivity from eggs harvested from local, wild populations, and released at two remnant prairies. Identifiable insect fragments were found in 94% of samples in 2013 (n=33) and 96% in 2014 (n=25). Frequency of occurrence of insects in turtle feces is similar to results reported in previous studies of midwestern Terrapene species. A comparison of insect composition presented no significant difference between release sites. There ...

Two New Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) From Hispaniola, Greater Antilles, Rolando Teruel, Gabriel De Los Santos
Two new species of Buthidae scorpions of the genus Tityus C. L. Koch, 1836 are herein described from the Greater Antillean island of Hispaniola. One of them belongs to the "crassimanus" species-group and is known from an adult pair collected at Massif de la Hotte, in southwestern Haiti. The other belongs to the "quisqueyanus" species-group and is known from a single adult female from a high peak in the Central Range (= Cordillera Central), in northwestern Dominican Republic. Moreover, two fossil taxa from this island are retained as junior synonyms of Tityus geratus Santiago-Blay, 1988†.
Water Quality Characterization And Mathematical Modeling Of Dissolved Oxygen In The East And West Ponds, Jamaica Bay Wildlife Refuge, John Tanacredi Ph.D., D Roy, Krishnanand Maillacheruvu
Dr. John T. Tanacredi
The current study was undertaken to characterize the East and West Ponds and develop a mathematical model of the effects of nutrient and BOD loading on dissolved oxygen (DO) concentrations in these ponds. The model predicted that both ponds will recover adequately given the average expected range of nutrient and BOD loading due to waste from surface runoff and migratory birds. The predicted dissolved oxygen levels in both ponds were greater than 5.0 mg/L, and were supported by DO levels in the field which were typically above 5.0 mg/L during the period of this study. The ...
Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz
Dr. John T. Tanacredi
Growth rates, body weight, density and biomass of ribbed mussels, Geukensia demissa (Dillwyn), were determined at Spartina alterniflora marsh-flat sites in Jamaica Bay, New York (Lower Hudson Estuary). Cumulative growth and annual growth increments varied but rates were lower at sites within the central bay relative to peripheral sites. Local variability both in size at Ring-1 and size-specific annual growth rates probably account for the variability in cumulative length. No pattersn were noted in frequency distributions of shell size but congruence in age structure was observed among neighboring sites in some areas of the bay. Mussel densities were greater within ...
Questioning Ecosystem Assessment And Restoration Practices In A Major Urban Estuary: Perpetuating Myths Of Degradation In Spite Of Facts, John T. Tanacredi Ph.D., Martin P. Schreibman, Kevin Mcdonnell
Dr. John T. Tanacredi
The Jamaica Bay ecosystem is a dichotomy. It encompasses more than 12,000 acres of coastal estuarine marshes and an ecological diversity rivaling any coastal environment in the world. It is considerably altered, and is affected by a variety of ecological insults directly related to the fact that more than 14 million people live in its vicinity. Environmental protection institutions responded to the challenge of protecting the bay, surrounding wetlands and recreational benefits by addressing the increasing load of contaminants into the ecosystem. Billions of dollars have been spent during the past five decades on restoration attempts, including upgrading wastewater ...

Dr. John T. Tanacredi
Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives ...
Naphthalenes Associated With Treated Wastewater Effluents In An Urban National Wildlife Refuge, John T. Tanacredi Ph.D.
Dr. John T. Tanacredi
Our coastal enviornments have become the invariable recipient of petroleum and petroleum wastes. Demands for petroleum products coupled with a lack of economic incentive to recycle waste oil, will increase the probability of greater concentrations of petroleum derived hyrdrocarbons entering our estuaries (CEQ Report, 1983).

Limulus In The Limelight: Exploring An Ancient Species, John Tanacredi Ph.D.
Dr. John T. Tanacredi
In an era when sports numbers shatter historical ceilings (especially in baseball) and fall by the wayside like fall leaves, a most enduring record of life continues to crawl along emerging from the sea early each spring pronouncing their incredible "record" of existences... over 350 million years. Now there is a number that even the rarified air of baseball salaries can admire. Yet, today the remarkable sea creature which endured over 100 million years of dramatically changing earth history prior to the existence of the dinosaurs, and which is comprised of only four species globally, is being tested for its ...
