A Study Of Teacher Practices And Perspectives On Nutrition Education In Maine Elementary Schools, Alexandra J. Courtney

Honors College

The purpose of this study was to identify how multiple influencing factors on nutrition education, relating to professional development, teacher self-efficacy, teacher beliefs, program use, wellness policies, and environmental factors, influence the amount of time elementary educators spend teaching nutrition in their classrooms. The primary tool for data collection was a comprehensive survey developed using Qualtrics software. The survey was distributed to Maine superintendents and principals who were asked to pass the survey along to K-5 teachers. Out of 270 responses collected before the survey end date, 233 were used for statistical analyses. The factors that influenced time teaching nutrition …

Penobscot River Restoration, Catherine Schmitt

Maine Sea Grant Publications

BETWEEN THE HEAD of tide above Bangor to where it widens into the bay at Searsport, the Penobscot River shifts from a flowing freshwater waterway banked by cedar and pine to a brackish, wave-lapped marsh with a rocky shoreline. In this estuary, salt concentrations fluctuate as the winds and tides push sea water and sediments back and forth. The estuary and the river that feeds it have taken on a new character recently, and have become an international example of watershed restoration. Despite two centuries of intensive timber harvesting and pulp and paper manufacturing, and the construction of hundreds of …

Measuring The Impact Of Pollution Closures On Commercial Shellfish Harvest: The Case Of Soft-Shell Clams In Machias Bay, Maine, Keith S. Evans, Kevin Athearn, Xuan Chen, Kathleen P. Bell, Tora Johnson

Publications

Temporary closures of polluted coastal waters to shellfish harvesting protect human health but also generate broad socioeconomic impacts on rural, fishing-dependent communities. Improved understanding of these impacts could help coastal managers prioritize investments to protect water quality and mitigate the effects of coastal pollution. Using a regression model of monthly landings, we explore the impact of temporary closures on the commercial harvest of soft-shell clams (Mya arenaria) in the Machias Bay region of Maine (USA). We find that economic losses are significant and depend heavily on tidal activity, and the size, frequency and timing of closures. Over the …

A Biochemical Approach To Define The Interactome For Calpain2 In Endothelial Cells, Dorothy E. Croall Phd, Jordan R. Hoffman Ms, Calvin Ph Vary Phd, Sharon L. Ashworth Phd, Billy R. Chase, Jay Beaudoin Ii

Molecular & Biomedical Sciences Faculty Scholarship

Current repositories for protein-protein interactions and high throughput screening methods focus on individual gene products and do not consider the significance of calcium induced conformational changes. These limitations suggest the need for alternative strategies to better define the calpain2 interactome. Affinity capture coupled with LC-MS/MS and proteomic analysis of the recovered proteins provides a powerful approach to identify protein-protein interactions for the heterodimeric calpain2. CAPN2 (rat) was modified to be catalytically incompetent (C105A) and fused with a C-terminal 15 residue peptide optimized for biotinylation by the biotin protein ligase, BirA. The resulting CAPN2*, heterodimerized with truncated CAPNS1, was purified from …

Aquaculture In Shared Waters Fact Sheet: Kelp Aquaculture, Sarah Redmond, Sam Belknap, Rebecca Clark Uchenna

Maine Sea Grant Publications

“Kelp” are large brown marine macroalgae species native to New England and traditionally wild harvested for food. There are three commercially important kelp species in Maine—sugar kelp (Saccharina latissima), winged kelp (Alaria esculenta), and horsetail kelp (Laminaria digitata). Maine is developing techniques for culturing kelp on sea farms as a way for fishermen and farmers to diversify their operations while providing a unique, high quality, nutritious vegetable seafood for new and existing markets. Kelp is grown on submerged horizontal long lines on leased sea farms from September to May, making it a “winter crop” for Maine. The simple farm design, …

Aquaculture In Shared Waters Fact Sheet: Getting To Know Your Water, Dana Morse, Samuel Belknap, Rebecca Clark Uchenna

Maine has significant potential to benefit from the successful integration of commercial fishing and the seafood business in the form of aquaculture and you have a chance to be involved in the beginning stages of this promising field. Aquaculture can be seen as a way to diversify on-the-water income and can easily complement existing fisheries businesses. There are risks associated with any business, however if managed properly aquaculture can be profitable.

Aquaculture In Shared Waters Fact Sheet: Site Selection, Dana Morse

Maine Sea Grant Publications

Site selection is the process of determining the optimum place for the sea farm. It’s a critical process, and will affect success - or failure. Crops grown on the wrong site may never do well, despite the best efforts of the farmer, and since obtaining a lease is usually a lengthy process, it’s not easy for a farmer to simply start up at a new site. The best approach is to do your homework thoroughly.

Aquaculture In Shared Waters Fact Sheet: Husbandry, Dana Morse, Samuel Belknap, Rebecca Clark Uchenna

Maine Sea Grant Publications

When people think of sea farming, it’s usually the husbandry part that they have in mind: tending the crop, working on the boat, etc. Husbandry is a rewarding part of the aquaculture process, and good husbandry is critical to success. Paired with strong financial management and sales and marketing, husbandry is where the rubber meets the road. Your goal as the farmer is very simple, but difficult to do well: Successful aquaculturists keep their animals and plants at optimum health. Another way to think about this is to keep the crop at minimum stress: low stress equals faster growth, improved …

Initial Movements Of A Dispersing Amphbian In Response To Partial Harvestion In The Acadian Forest Of Maine, Usa, Brittany Cline, Malcolm L. Hunter Jr.

Publications

Maintaining amphibian populations in managed forests requires a balance between timber extraction and retaining functional connectivity for animals that use multiple vegetation types to satisfy habitat requirements, particularly where extensive harvesting may increase fragmentation. Quantifying dispersal patterns in response to harvest, especially across high-contrast edges adjacent to unlogged forest, is critical for evaluating the effects of harvest configuration on amphibians. We tested the initial post-metamorphic orientation of juvenile wood frogs (Lithobates sylvaticus) at edges in harvests (31– 60% retention standwide) in the Acadian forest of Maine, USA, during the period when juveniles emigrate from breeding pools. We released juveniles (n …

The Effects Of Rotation And River Discharge On Net Mixing In Small-Mouth Kelvin Plumes, Kelly Cole, Robert D. Hetland

Publications

Small-mouth Kelvin number plumes, or plumes with a source width smaller than the deformation radius, are characterized by near-field plume regions of rapid lateral expansion and strong vertical mixing. Net plume mixing, or the dilution of a plume by ocean water between the estuary mouth and the far-field plume, is examined using idealized numerical experiments with the Regional Ocean Modeling System (ROMS). The density anomaly of plume water entering the far field is determined from isohaline analysis of the modeled salinity field. The experiments indicate that when estuarine discharge increases, net plume mixing decreases in a rotating environment but increases …

Interaction Of Shading And Cytokinins In The Sun-Shade Foliar Adaptation Mechanism, Oleg S. Gross

Honors College

Plants, being sessile, address environmental changes and resource constraints by means of developmental plasticity. For example, plants maximize photosynthesis driven carbohydrate production by undergoing physiological and structural changes in response to their environmental conditions. This plasticity to light environment has several potential regulatory pathways that may include light intensity and light spectral quality. Hypotheses advanced to associate foliar plasticity to light intensity include sensing products of photosynthesis and regulation by the phytohormone cytokinin. In this study, we examined the interacting roles of the cytokinin 6-Benzylaminopurine (BAP) and light intensity in the regulation foliar plasticity. Exogenous application of BAP was used …

The story is divided into four loose categories; the growing, the loving, the hurting and the healing. The growing explores puberty, and the importance of puberty in terms of creating more mature relationships. The loving defines when the main character, Clara, falls in love with the antagonist. She eventually gets her heart broken and she has to learn how to heal from that. The hurting is her heartbreak; the …

Anthocyanins Alter Endothelial Cell Dynamics, Katrina E. Ventura

Honors College

Cardiovascular disease is the leading cause of death in the United States. Previous studies suggest that a diet high in blueberries correlates with lower rates of heart disease and improved endothelial cell function. Anthocyanins, which are phenolic compounds, are known components of wild blueberry extracts. Studies suggest that cells treated with anthocyanins have increased migration and increased VEGF (vascular endothelial growth factor) production. VEGF activates a signal cascade that ultimate leads to the activation of Hsp27 (heat-shock protein 27) and LIMK (LIM-kinase). Cofilin, which is phosphorylated by LIMK, is an important protein involved in cellular migration, and plays a role …

Towards A Molecular Method For The Detection Of Leaf Rust In Lowbush Blueberry, Steven Valentino

Honors College

Thekopsora minima, or leaf rust, is a fungal pathogen that infects Vaccinium angustifolium (lowbush blueberry), an economically important crop to the state of Maine. T. minima undergoes a complicated life cycle that contains five unique spore stages. It causes abscissions in the leaves of plants that may consequently lower yields in the next growing cycle if leaf drop is severe. Currently, growers are instructed to apply fungicides in late July to prevent further infection. However, this is often not effective due to poor timing. Data on spore release patterns would be beneficial to elucidate the infection period. However, microscopic identification …

Novel Role For A Neurotrophic Factor In White Adipose Tissue, Elizabeth Wood

Honors College

Neurotrophic factors are a family of growth factors that regulate neuronal plasticity. Thus far, these factors have been understudied in peripheral tissues, including adipose tissues, where they could play a key role in mediating the neuronal inputs that lead to energy expenditure via lipolysis (white fat) and thermogenesis (brown fat). Based on prior experiments, we hypothesized that brain derived neurotrophic factor (BDNF) is the main neurotrophic factor acting in adipose tissues to mediate neurite outgrowth and branching of incoming sympathetic nerves. We found that BDNF knock-out animals had less innervation of their white fat, shown by reduced expression of neuronal …

The Role Of Neutrophil Cytosolic Factor 1 In The Innate Immune Response To Influenza A Virus, Lucy D. Algeo

Honors College

Influenza A Virus (IAV) causes over 21,000 deaths annually in the United States alone. The innate immune response to IAV includes the production of reactive oxygen species (ROS) via NADPH oxidase. ROS are known to impact signaling pathways and cellular processes in order to eliminate IAV, but can cause permanent damage to lung epithelial cells in the process. One gene involved in the production of ROS is Neutrophil Cytosolic Factor 1 (ncf1), which codes for a subunit of NADPH oxidase. Mutations in ncf1 have been correlated with chronic granulomatous disease, chronic inflammation, and autoimmunity. Studying ncf1 in response to IAV …
