Ranging And Behavior Of Black And Gold Howler Monkeys In Formosa, Argentina, Claire Rossi De Leon May 2019

Ranging And Behavior Of Black And Gold Howler Monkeys In Formosa, Argentina, Claire Rossi De Leon

Library Map Prize

Howler monkeys (Alouatta spp.) are known for their adaptability, allowing them to inhabit a large range of forest types and driving high levels of variation in ranging and behavioral patterns. I address a series of hypotheses relating these relationships: 1) If an energy minimizing lifestyle is an adaptation to eating high quantities of leaves, then howler groups that have a high proportion of leaves in their diet will occupy smaller home ranges, have shorter daily path lengths, and spend more time resting, 2) if temperature is the primary driver of high levels of resting, then howlers will conserve energy and ...


The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring; Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species., Robert J. Posont Apr 2019

The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring; Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species., Robert J. Posont

Theses and Dissertations in Animal Science

Our first study identified the effects of maternal inflammation-induced intrauterine growth restriction (MI-IUGR) on growth and muscle glucose metabolism in offspring supplemented with curcumin. MI-IUGR lambs exhibited asymmetric growth restriction at birth and 30d of age, but normal glucose-stimulated insulin secretion. Hindlimb glucose oxidation was reduced by MI-IUGR and not improved by curcumin supplementation. Ex vivo muscle glucose oxidation was reduced by MI-IUGR but improved somewhat by curcumin. These finding indicate that fetal programming responses to MI contribute to neonatal growth and metabolic deficits. Neonatal curcumin supplementation had minimal effect on growth deficits but may improve glucose metabolism.

The Most Critical Resource: How Climate Change Fuels The Crisis In Syria And The Implications For The World At Large, Edward Medeiros Apr 2019

The Most Critical Resource: How Climate Change Fuels The Crisis In Syria And The Implications For The World At Large, Edward Medeiros

Honors College

The Syrian crisis, both domestic and international in scope, may well be the defining geopolitical challenge of the generation. Climate change may be the single greatest challenge to face humanity in the entirety of our species’ life history. The dramatic effects of climate change can be seen in the origins of the Syrian crisis when one looks to humanity’s single most critical resource: water. We take the word critical to have two meanings in this context: first, that water is essential to human survival and second that water is a resource in critical condition. Syria’s water crisis pre-dates ...


An Intersectional Feminist Approach To Lyme Disease Epidemiology, Meghan Frisard Apr 2019

An Intersectional Feminist Approach To Lyme Disease Epidemiology, Meghan Frisard

Honors College

Nationally, Maine is the state with the second highest incidence of Lyme disease. While the spread of Lyme disease is generally attributable to ecological factors that affect the life cycle of Lyme-spreading ticks, socioeconomic factors may have substantial impacts on diagnosis and reporting of human cases. Socioeconomic factors could influence one’s ability to see a healthcare provider and ultimately be diagnosed with and treated for Lyme. Additionally, access to and treatment within the healthcare system is often gendered. I hypothesize that certain socioeconomic factors will have a negative correlation with Lyme disease incidence among the general population and among ...


Mmp13 Inhibition Does Not Rescue Gmppb-Deficient Skeletal Muscle In Zebrafish, Sean Driscoll Apr 2019

Mmp13 Inhibition Does Not Rescue Gmppb-Deficient Skeletal Muscle In Zebrafish, Sean Driscoll

Honors College

The dystroglycan protein is one of many that attach skeletal muscle fibers to the basement membrane at the myotendinous junction. In the alpha-subunit of the dystroglycan molecule, there are sugar chains that help with the adhesion of the molecule to the basement membrane. A mutation in any gene that codes for an enzyme that adds these sugar chains can result in a form of congenital muscle disease called secondary dystroglycanopathy. One of the genes that codes for an enzyme that adds sugar chains is GMPPB and a mutation in this gene results in GMPPB-associated dystroglycanopathy. Using zebrafish as a model ...

Construction Of A Cpsa Double Mutant To Determine The Function Of The Lyt-R Domain, Klarissa Klier

Honors College

Streptococcus agalactiae, otherwise known as Group B Streptococcus (GBS), is a zoonotic, Gram-positive, commensal and invasive bacteria which is the leading cause of neonatal bacterial infections. These bacterial infections include sepsis, meningitis, pneumonia, and bacteremia. In neonates, GBS is most commonly transferred to the child in utero or during birth when the child aspirates amniotic or vaginal fluids. GBS can also infect the child through the bloodstream while in utero, causing premature births or still births. Children who survive the initial infection develop severe morbidities which include mental retardation, cerebral palsy, and seizures. GBS can also affect immunocompromised adults, leading ...


Camera Trap Study Of The Mammal Communities Across An Urbanization Gradient, Caleb Durbin, Christine Brodsky Apr 2019

Camera Trap Study Of The Mammal Communities Across An Urbanization Gradient, Caleb Durbin, Christine Brodsky

Posters

Urbanization impacts mammal communities due to habitat removal, resource abundance distribution, and the introduction of exotic species. Other studies have found that wildlife species richness is greatest at intermediate urbanization, while abundance is greatest in cities. This study was done to explore the mammal community across an urban to rural gradient in Pittsburg. Using motion-sensor camera traps, we documented small mammal pres­ence for 24 hours a day, finding patterns in mammal abundance, species richness, and community composition. Our hypothesis was that we will observe trends in mammal communities similar to other cities. Over six weeks, we placed two cameras ...

Quantitative Heterodonty In Crocodylia: Assessing Size And Shape Across Modern And Extinct Taxa, Domenic D'Amore, Megan Harmon, Stephanie Drumheller, Jason Testin Feb 2019

Quantitative Heterodonty In Crocodylia: Assessing Size And Shape Across Modern And Extinct Taxa, Domenic D'Amore, Megan Harmon, Stephanie Drumheller, Jason Testin

Faculty Articles

Heterodonty in Crocodylia and closely related taxa has not been defined quantitatively, as the teeth rarely have been measured. This has resulted in a range of qualitative descriptors, with little consensus on the condition of dental morphology in the clade. The purpose of this study is to present a method for the quantification of both size- and shape-heterodonty in members of Crocodylia. Data were collected from dry skeletal and fossil specimens of 34 crown crocodylians and one crocodyliform, resulting in 21 species total. Digital photographs were taken of each tooth and the skull, and the margins of both were converted ...


The Endangerment Of The Nubian Giraffe, Alexa Casacci Jan 2019

The Endangerment Of The Nubian Giraffe, Alexa Casacci

Academic Festival Posters

The Nubian Giraffe (Giraffa camelopardalis) is a large herbivore that resides in the African savanna. Due to habitat loss, habitat fragmentation, habitat degradation, poaching, and human population growth, this species has been declining. The current estimate of Nubian giraffes is 2,645. Conservation efforts include relocating the giraffes to wildlife reserves and creating National Strategies/Action Plans in which countries in Africa are enlightened on how to assess threats, limit resources, and monitor the species. My poster will investigate which conservation plan works best and what other methods may help in saving this species.

Conservation Of The Pig-Nosed Turtle, Joanna Budzynski

Academic Festival Posters

The pig-nosed turtle (Carettochelys insculpta) is an omnivore that can grow up to 70cm in length. They are found in the freshwater wetlands of Australia, Indonesia, and Papua New Guinea. Carettochelys insculpta is the only surviving member of the genus Carettochelys and the family Carettochelyidae. The pig-nosed turtle is listed as endangered due to flooding, habitat destruction, and human egg collection for consumption of turtles by the indigenous people. In addition, the pet trade traps and sells these turtles. The total population number is unknown; however, it is known that the population has declined by 50% since 1981. Conservation efforts ...

Conservation Of The Polar Bear, Maya Rutherford

Academic Festival Posters

The polar bear (Ursus maritimus) is a large carnivore found on the sea ice of the Arctic Ocean. As a result of climate change, the melting of the sea ice has listed this species as vulnerable. Polar bears depend on ice for their existence and play an important role in the overall health of the marine environment. Current conservation efforts have focused on preserving the biodiversity in the Arctic by reducing industrial impacts. This poster will evaluate the current conservation plans for this species and offer alternative solutions.


Snow Leopard (Panthera Uncia) Vulnerability, Savannah Warner Jan 2019

Snow Leopard (Panthera Uncia) Vulnerability, Savannah Warner

Academic Festival Posters

The Snow Leopard (Panthera uncia) is a vulnerable species on its way to endangerment. Its population size is around 3,000 individuals who reside in mountainous regions in Asia. The population decline of snow leopards is due to hunting and trapping, problematic native species/diseases, and human encroachment on their habitat. While there are some conservation efforts already in place through action recovery plans, education and awareness programs, trade control, and conservation areas, there is still more that can be done. This poster will discuss the reasons for snow leopard vulnerability and ways conservation efforts can affect the snow leopard ...


Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines Jan 2019

Trade-Offs Shape Carotenoid-Based Color Variation In Redheaded Pine Sawfly (Neodiprion Lecontei) Larvae, Maranda Gaines

Lewis Honors College Capstone Collection

Carotenoids serve various ecological roles in animals including coloration, immune responses, and vision. Carotenoid-derived coloration is greatly emphasized in the literature, particularly relating to mate choice and aposematic warning. However, the trade-offs between the color and non-color functions of carotenoids are not thoroughly explored. In the redheaded pine sawfly (Neodiprion lecontei), some larval populations have yellow pigmentation, using carotenoids derived from their diets for aposematic warning coloration. Other larval populations are white in color, having genetically lost the ability to produce the yellow pigment. Because carotenoids are essential to life functions in both the yellow and white populations, we aim ...

Conservation Isn't Irrelephant!, Elizabeth Potalivo

Academic Festival Posters

The Borneo pygmy elephant (Elephas maximus borneensis) is an endangered subspecies of the Asian Elephant. It differs both physically and behaviorally from other Asian elephants. The Borneo pygmy elephant is found in Malaysia and Borneo. Only 1,000-1,600 of the individuals remain due to habitat loss for oil palm plantations and human-elephant conflicts. Several conservation plans exist which target the protection of migratory paths for the elephants and identify where palm oil plantations may be established. This poster will evaluate these existing plans and propose additional strategies to aid in the conservation efforts for the Borneo pygmy elephant.


Novel Habitat Causes A Shift To Diurnal Activity In A Nocturnal Species, J. Sean Doody, Colin R. Mchenry, David Rhind, Simon Clulow Jan 2019

Novel Habitat Causes A Shift To Diurnal Activity In A Nocturnal Species, J. Sean Doody, Colin R. Mchenry, David Rhind, Simon Clulow

Faculty Publications

Plastic responses may allow individuals to survive and reproduce in novel environments, and can facilitate the establishment of viable populations. But can novel environments reveal plasticity by causing a shift in a behavior as fundamental and conspicuous as daily activity? We studied daily activity times near the invasion front of the cane toad (Rhinella marina), an invasive species that has colonized much of northern Australia. Cane toads in Australia are nocturnal, probably because diurnal activity would subject them to intolerably hot and dry conditions in the tropical savannah during the dry season. Our study can demonstrate, however, that upon reaching ...

Rediscovery Of Red Wolf Ghost Alleles In Canid Population Along The American Gulf Coast, Elizabeth Heppenheimer, Kristin Brzeski, Ron Wooten, William Waddell, Linda Y. Rutledge, Michael J. Chamberlain, Et. Al.

School of Forest Resources and Environmental Science Publications

Rediscovering species once thought to be extinct or on the edge of extinction is rare. Red wolves have been extinct along the American Gulf Coast since 1980, with their last populations found in coastal Louisiana and Texas. We report the rediscovery of red wolf ghost alleles in a canid population on Galveston Island, Texas. We analyzed over 7000 single nucleotide polymorphisms (SNPs) in 60 canid representatives from all legally recognized North American Canis species and two phenotypically ambiguous canids from Galveston Island. We found notably high Bayesian cluster assignments of the Galveston canids to captive red wolves with extensive sharing ...

School of Forest Resources and Environmental Science Publications

The threatened eastern wolf is found predominantly in protected areas of central Ontario and has an evolutionary history obscured by interbreeding with coyotes and gray wolves, which challenges its conservation status and subsequent management. Here, we used a population genomics approach to uncover spatial patterns of variation in 281 canids in central Ontario and the Great Lakes region. This represents the first genome-wide single nucleotide polymorphism (SNP) dataset with substantial sample sizes of representative populations. Although they comprise their own genetic cluster, we found evidence of eastern wolf dispersal outside of the boundaries of protected areas, in that the frequency ...


Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes Dec 2018

Painted Ferocity: The Social Behaviors Of African Wild Dogs, Threats To Survival, And Resulting Conservation Initiatives, Alexis Valdes

Senior Honors Theses

African Wild Dogs (Lycaon pictus) are an endangered species of canid from Sub-Saharan Africa. They are very social communal hunters, and are capable of chasing down prey for long stretches of time. Wild dogs benefit a savannah ecosystem by regulating the populations of their prey so that it does not become unhealthy and overgrown. Like many organisms, wild dogs are also in competition with other predators for resources, namely lions and hyenas, who are capable of stealing their kills and occasionally injuring and killing them. Due to the depletion of their wild prey, wild dogs may also prey upon farmers ...

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Natural history collections spanning multiple decades provide fundamental historical baselines to measure and understand changing biodiversity. New technologies such as next generation DNA sequencing have considerably increased the potential of museum specimens to address significant questions regarding the impact of environmental changes on host and parasite/pathogen dynamics. We developed a new technique to identify intestinal helminth parasites and applied it to shrews (Eulipotyphla: Soricidae) because they are ubiquitous, occupy diverse habitats, and host a diverse and abundant parasite fauna. Notably, we included museum specimens preserved in various ways to explore the efficacy of using metabarcoding analyses that may enable ...
