Land Cover Composition, But Not Weather, Affects Female Wild Turkey Roost Site Selection, Kaj Overturf

Honors College

Populations at a species’ northern range extent are often presented with more challenges than those in more southern regions, given that winters are generally harsher, and the reproductive season is shorter in these northern regions. Wild turkeys (Meleagris gallopavo) are near their northern range limit in Maine, and there have been no studies that have researched turkey roosting here. Wild turkeys roost in trees at night, and we predicted that roost selection would be affected by changing weather conditions, particularly during winter when temperatures are expected to be coldest. We also predicted that land cover composition would affect …

Cpsa Protein-Protein Interactions In Group B Streptococcus, Ben Tero

Honors College

Group B Streptococcal (GBS) infections pose a great threat to mortality in neonates. Neonates are often exposed to GBS both before, during, and after delivery, which can cause a range of health problems including meningitis, sepsis, or stillbirth. One of the major virulence factors that contributes to the infectivity of the pathogen is the bacterial capsule. The capsule is a polysaccharide matrix surrounding the cell which helps in the evasion of host defenses, and penetration into normally sterile sites like the bloodstream. The highly conserved GBS protein CpsA has been shown to regulate expression of the capsule. The objective of …

Framing The Discussion Of Microorganisms As A Facet Of Social Equity In Human Health, Suzanne L. Ishaq, Maurisa Rapp, Risa Byerly, Loretta S. Mcclellan, Maya R. O'Boyle, Anika Nykanen, Patrick J.

What do “microbes” have to do with social equity? These microorganisms are integral to our health, that of our natural environment, and even the “health” of the environments we build. The loss, gain, and retention of microorganisms—their flow between humans and the environment—can greatly impact our health. It is well-known that inequalities in access to perinatal care, healthy foods, quality housing, and the natural environment can create and arise from social inequality. Here, we focus on the argument that access to beneficial microorganisms is a facet of public health, and health inequality may be compounded by inequitable microbial exposure.

Beyond that it could make for some tasty options on the menu the next time you visit your favorite seafood restaurant.

S1e1: What Is Edna And How Will It Change Maine’S Coastal Communities?, Ron Lisnet, Michael Kinnison

The Maine Question

From streams and ponds to the Gulf of Maine, water defines the state of Maine in many ways. For thousands of years, counting or harvesting the plants and animals in those bodies of water has been pretty low-tech, usually involving nets of some sort. Now a new technology can do this counting using DNA and this tool will revolutionize and expand how this work is done. Beyond that it will allow the public, school groups, coastal residents and others to contribute as citizen scientists and it will enhance Maine’s workforce and promote high-tech jobs as well.

Effect Of Hydroculture Methods On Tomato Root Morphology And Anatomy, Lia Maclellan

Honors College

Three methods of hydroculture were compared for their effects on the root anatomy and morphology of tomato (Solanum lycopersicum cv. Defiant). A hydroponic deep water culture method, an ebb-flood system using expanded clay pellets as a solid medium and an aeroponic sub-mist system were compared, with a solid peat/perlite medium for control. The treatments were found to have significant effects on plant root and shoot length, as well as root and shoot biomass. Root morphology was visually distinct among treatments, and all methods of hydroculture were associated with a significant increase in vascular tissue in plant roots compared with the …

Localization Of Synapses On Adipocytes And Stromal Vascular Fraction Cells In Adipose Tissue Using Electron And Immunofluorescent Microscopy, Emma Garner

Honors College

Obesity, weight gain and the many metabolic disorders that can arise from being overweight are predominant health issues in America and in the State of Maine. The body’s ability to balance energy intake and energy expenditure is what determines whether a person gains or loses body fat. Although there are many different factors that influence energy storage and expenditure, neural innervation of white and brown fat (or adipose) tissues is an important aspect of energy balance that is not well understood. The Townsend Lab focuses on brain-adipose communication and the role of adipose peripheral nerves in maintaining proper body weight …

The Potential Roles Of Melanopsin Signaling In Mediating The Effects Of Environmental Light On Voluntary Ethanol Intake In Mice, Rachel Brooks

Honors College

Intrinsically photosensitive retinal ganglion cells (ipRGCs) comprise a small subset of photoreceptors found in the eye containing the newly discovered photopigment, melanopsin. ipRGCs project directly to the hypothalamic suprachiasmatic nucleus (SCN), the central “pacemaker” underlying the generation and entrainment of circadian rhythms. Photic stimuli detected by ipRGCs are transmitted to the SCN via the retinohypothalamic tract (RHT), mediating the entrainment of the SCN pacemaker. In addition to circadian entrainment, these pathways may also contribute to seasonal changes seen in both animals and humans, such as seasonal breeding cycles in animals and seasonal affective disorder in humans. Our lab has recently …

Evaluating A Doppler Radar Monitor For Assessing Honey Bee Colony Health, Ana Eliza Souza Cunha

Honors College

Honey bees pollinate an estimated $15 billion worth of crops each year. It is therefore vital that beekeepers assess the productivity and health of colonies in order to reassure the reproductive future of this species. Modern techniques in which beekeepers can assess honey bee colony health are labor intensive, costly, and invasive to the bees as they must open and rearrange the hive to assess colony health. A radar-based sensor, placed outside of the hive, can be used to assess colony activity and health in a non-invasive manner. In order to validate the function of this hive monitor and quantify …

The Effect Of Embryonic Arsenic Exposure On The Sensorimotor Behavior Of Zebrafish (Danio Rerio), Laura Paye

Honors College

The goal of this study is to determine the effect of arsenic exposure on vision in zebrafish (Danio rerio). The optic system of D. rerio is ideal for examining visual defects. Their eyes are similar to eyes of humans and can therefore be useful models in studies of human eye disease. Their optic system functions similarly to humans, so it is beneficial to observe how zebrafish are affected by contaminants in the environment. Arsenic is ubiquitous in groundwater, due to its natural presence in bed rock, but is elevated by human activities. In order to see any …

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

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, …

The Effects Of European Fire Ants On Blacklegged Ticks In Acadia National Park, Lucy Guarnieri

Trials And Tribulations Of Modern Day Childbirth: A Literature Analysis Of Factors Contributing To The Recent Decline In Vaginal Birth After Cesarean Delivery, Camilla Horton

Honors College

C-sections are an extremely common procedure in modern day America, and while there are serious indications for cesarean delivery including complications for mother and baby, there are likely far more cesareans performed each year than medically necessary. This A comprehensive literature analysis was compared to individual data collection from the Center for Disease Control and Prevention’s National Vital Statistics System. Both the analysis of the literature and the individual data collection confirmed that cesarean deliveries in the US have increased to from less than 10% in the 1970s, to over 30% in the years following 2005. Vaginal birth after cesarean …

Landscape Factors Affecting Foraging Flight Altitudes Of Great Blue Heron In Maine; Relevance To Wind Energy Development, Lauren Dolinski

Honors College

In an attempt to increase alternative energy sources, there has been greater development of wind farms across the United States. This expanded development may pose a potential threat to birds that are flying overhead (EIA 2017, Leung and Yang 2011). More information is needed on the factors that affect a bird’s behavior while flying and if the current policies and dimensions of wind turbines interfere with flight altitudes. We used data from GPS-marked great blue herons (Ardea herodias) in Maine to classify their flight altitudes relative to wind turbine height and assess different landscape factors that affect flight …

Do Different Methods Of Communication Impact Undergraduate Student's Knowledge, Attitudes, & Beliefs Towards White-Nose Syndrome In Little Brown Bats, Kiley Davan

Honors College

White-nose syndrome (WNS) is a deadly fungal disease that has killed millions of hibernating bats since its introduction to North America in 2006. The little brown bat (Myotis lucifugus), once widespread across the US, has been the most severely impacted with some colonies experiencing a 99% decline. Scientists believe changing people’s behavior is the key to bat conservation as the fungus is spread primarily by humans transferring the fungus between bat colonies. Outreach is a common method used to affect behavioral change in people, but not all outreach methods are equally effective. The purpose of this study was …
