The Role Of Personality In Large Nut Dispersal By Sciurus Carolinensis And Its Implications For Seed Dispersal Across Human-Modified Landscapes, Skye Cahoon
Honors College
Small mammals are well known seed dispersers, but their efficiency at seed dispersal is directly affected by their personality type. Anthropomorphic habitat change shifts the distribution of personalities within small mammal populations, thus altering the mechanisms by which seeds are dispersed across these areas. Little is known about how small mammals interact with sidewalks, roads, or parking lots during the seed dispersal process despite these areas’ prevalence within human modified landscapes and the importance of understanding the ways in which seeds are transported across anthropomorphically altered regions. The goal of this study is to explore the role of personality in …
Mmp13 Inhibition Does Not Rescue Gmppb-Deficient Skeletal Muscle In Zebrafish, Sean Driscoll
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 …
The Most Critical Resource: How Climate Change Fuels The Crisis In Syria And The Implications For The World At Large, Edward Medeiros
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 the civil …
Construction Of A Cpsa Double Mutant To Determine The Function Of The Lyt-R Domain, Klarissa Klier
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, …
An Intersectional Feminist Approach To Lyme Disease Epidemiology, Meghan Frisard
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 women, …
The Effects Of The Hemlock Woolly Adelgid On Abundance And Nymphal Infection Prevalence Of Black-Legged Ticks In Maine, Spencer Christian Debrock
The Effects Of The Hemlock Woolly Adelgid On Abundance And Nymphal Infection Prevalence Of Black-Legged Ticks In Maine, Spencer Christian Debrock
Honors College
The black-legged tick (Ixodes scapularis) has recently made a tremendous impact in Maine due to its role as a vector for the bacterial pathogen Borrelia burgdorferi, the causative agent of Lyme disease. A lesser known, but equally concerning, invasive insect is the hemlock woolly adelgid (HWA; Adelges tsugae), a sap-sucking scale that is primarily responsible for the ongoing widespread decline of eastern hemlock in the northeast. Maine is currently experiencing a co-invasion of these species, and this study tests the hypothesis that the phenomenon of hemlock loss may facilitate the invasion of the black-legged tick by …
Construction Of An Accessible Ocean-Acidification Simulator To Investigate Physiological Responses Of The Green Crab, Carcinus Maenas, To Acidified Conditions, Caroline M. Spangenberg
Construction Of An Accessible Ocean-Acidification Simulator To Investigate Physiological Responses Of The Green Crab, Carcinus Maenas, To Acidified Conditions, Caroline M. Spangenberg
Honors College
The European green crab Carcinus maenas L, is a major invasive species in North America as well as many other regions around the world, including South Africa, Australia, South America, and Asia. The species poses a significant threat to the diverse ecosystems and the aquaculture industries on the East coast of the United States, with the state of Maine particularly at risk. The shellfish industry is a significant part of Maine’s economy, and is threatened by the foraging behavior of green crabs toward small bivalves (Beal 2015). Climate change likely plays a large role in the rapid population growth of …
Assessing The Impacts Of Commercial Clearcut On Freshwater Invertebrate Communities, Nicholas J. Kovalik
Assessing The Impacts Of Commercial Clearcut On Freshwater Invertebrate Communities, Nicholas J. Kovalik
Honors College
Forest harvesting can impact the environment in many ways, one of which is causing a loss of subsidies and increased light intensity to freshwater ecosystems. This can have a major impact on freshwater invertebrate communities that may rely on subsidies to survive. In this study, I tested two effects of commercial clearcut, changes in light availability and detrital resources, on freshwater invertebrate communities. Cattle tanks containing freshwater invertebrates were given detritus from two different plots: one which underwent commercial clearcut over 50 years ago, and one which underwent commercial clearcut 2 years ago. Tanks were also placed in two areas …
Do Insulating Characteristics Of Feathers Vary Among Color Phases Of Ruffed Grouse (Bonasa Umbellus)?, Nicole Keefner
Do Insulating Characteristics Of Feathers Vary Among Color Phases Of Ruffed Grouse (Bonasa Umbellus)?, Nicole Keefner
Honors College
Ruffed grouse (Bonasa umbellus) occupy a wide distribution in North America, from Georgia in the south to Alaska in the north, as well as southern and central Canada. Color phases in ruffed grouse range from red to gray with gray phase birds found more frequently at higher latitudes than red birds. Gray and red morphs become exclusive at northern and southern range margins, respectively. This pattern is generally attributed to increased ability of gray morphs to survive northern winters. Although a number of mechanisms have been proposed for these relationships, recent studies on tawny owls have suggested that …
The Importance Of Social Science In Biomedical Education, Kathryn Asalone
The Importance Of Social Science In Biomedical Education, Kathryn Asalone
Honors College
This study proposes an intervention in undergraduate education that could enhance doctor-patient interactions. This intervention would provide evidence, to pre-medical students, that social science training is important during medical school. Semi-structured interviews were conducted of six doctors from hospitals in the Maine. The goal was to determine whether or not taking more social science courses during an MD’s undergraduate education would result in better reported doctor satisfaction with their patient interactions. The interview questions were designed to encourage doctors to explain how they interact with patients and coworkers and to describe their undergraduate education. This information and the impressions that …
Exploring The Mechanisms Involved In Paxillin Amerlioration Of Dystrophies In Zebrafish, Margaret E. Pasquarella
Exploring The Mechanisms Involved In Paxillin Amerlioration Of Dystrophies In Zebrafish, Margaret E. Pasquarella
Honors College
Muscle cells must anchor to their environment, the extracellular matrix (ECM), in order to function properly. Muscular dystrophy occurs when muscle cells cannot anchor to the ECM because specific protein complexes, such as the dystroglycan complex, are disrupted. Previously published studies have shown that overexpressing Paxillin can reduce dystrophy in dag1 deficient embryos. The aim of this study is to determine which domains of Paxillin are necessary to rescue dystrophy by overexpressing Paxillin with the LD2 or LD4 domains knocked out in dystrophic embryos. However, disruption of Dag1 via the previous method stopped producing the muscular dystrophy phenotype, so ethanol …
Foraging Behavior Of Eastern Gray Squirrels On The University Of Maine Campus, Aimee Young
Foraging Behavior Of Eastern Gray Squirrels On The University Of Maine Campus, Aimee Young
Honors College
The goal of this study was to observe the foraging behavior of Eastern Gray Squirrels (Sciurus carolinensis) on the University of Maine campus. The study tested whether squirrels in a more urban setting followed the optimal foraging theory, or if rarity of a food type played a greater factor in food selection. The study also examined whether urban squirrel behavior mimicked that of wild squirrels when presented with a food type uncommon on campus, but common in other parts of Maine, specifically the acorns of the white oak tree (Quercus alba). In three different areas on the campus, squirrels were …
The Phylogeny And Biogeography Of The Monito Del Monte (Dromiciops Gliroides) And Its Relatives, Ariel Berthel
The Phylogeny And Biogeography Of The Monito Del Monte (Dromiciops Gliroides) And Its Relatives, Ariel Berthel
Honors College
Marsupials are a group of mammals that give birth to young that are not fully developed. These offspring must complete the remainder of their development outside of the womb attached to their mother’s teat. Marsupials only occur in South America and Australasia, with one species extending into North America. The marsupial known as the monito del monte, which is Spanish for ‘little monkey of the mountain,’ (Dromiciops gliroides) is a South American marsupial; however, it shares a key morphological feature of ankle bone morphology with Australasian marsupials. This shared, derived trait is what defines the cohort Australidelphia, to which the …
Mammals Of Maine, Ralph S. Palmer
Mammals Of Maine, Ralph S. Palmer
Honors College
The present paper was undertaken in order that the compiler might gain a slight knowledge of Maine mammals and the literature pertaining to this branch of zoology. It was undertaken as a "major honors" course at the University of Maine for the school year of 1936-1937. It is possible that a perusal of this paper will reveal to others the striking scarcity of information on many of our mammalian forms. All the endemic forms known to have occurred in Maine within historic times are listed. Some of these forms are extirpated at the present time. Introduced species are not treated.
