Form And Risk Class Distribution And Its Effect On Estimated Product Ratios In Commercial Species Commonly Found In Northeastern Forests And A Comparative Analysis Of Contrasting Field Inventory Methodologies, Ryan Smith

Electronic Theses and Dissertations

Estimating product ratios in hardwood forests is difficult due to the highly complex stem forms and diverse growth and regeneration strategies found in hardwood species. This is of particular concern for landowners with large ownerships requiring robust product potential estimates as part of both short-term tactical harvest planning and long-term growth and yield projections. Hardwood-dominated forests are generally managed for high-value sawlog and veneer products. This makes it increasingly important to identify strategies for improving hardwood management to meet economic (maximizing sawlog recovery) and ecological (maintaining healthy and diverse forests) goals.

This study seeks to achieve two primary goals. The …

Exploring Reusable Takeout Packaging As An Alternative To Disposable Plastics In Maine's Restaurant Industry, Jared Wildwistle

Electronic Theses and Dissertations

Since the emergence of plastic over 100 years ago, businesses have increasingly relied on them to protect products. While convenient, the proliferation of plastic packaging is a major contributor to pollutants in the soil, oceans, and bodies of humans and animals alike. Goals in states like Maine seek to reduce the amount of waste and alleviate these issues. However, the deeply embedded popularity of disposable packaging and lack of reliable waste processing capabilities has caused Maine to fall short of its goals. While solutions need to focus on reducing the amount of packaging entering the economy, most businesses rely on …

A Sky Island Perspective: New England Alpine Plant Distributions Across The Region, Andrea Tirrell

Electronic Theses and Dissertations

Alpine ecosystems around the globe are at risk due to climate change, human disturbance, and habitat loss. New England alpine zones are small and fragmented, which could make them vulnerable to global change. However, the persistence of tundra relics throughout the Holocene suggests the persistence of these communities in microclimate refugia. Assessing the near-term vulnerability of alpine plant communities is challenged by a lack of standardized, repeat surveys and long-term monitoring data, which presents a challenge for the many agencies monitoring New England’s alpine zones. Island biogeography theory predicts that alpine species richness is a function of area, but this …

Assessment Of Historical Climate Variability In Maine With Implications For Future Agricultural Productivity And Adaptation, Carly Frank

Electronic Theses and Dissertations

Climate change is a wicked problem with global impacts, one of which being the sustainability of the existing global food system. As temperatures and variability in precipitation are projected to increase, the challenges to agriculture are expected to intensify. This thesis examines the Maine historical climate record over the growing season, in combination with future projections, to assess how conditions have changed and will change with agricultural implications. In this analysis, relevant climatic variables are analyzed, and agriculture-significant measures are derived for Maine’s three climate divisions using four decades of daily and monthly gridded datasets. In addition, this thesis explores …

Bound By Print: The Baptist Borderlands Of Maine And The Canadian Maritimes, 1770-1840, Brittany P. Goetting

Electronic Theses and Dissertations

Asynchronous communication was essential for the development of the cross-border and global identities of Baptists in Maine and the Canadian Maritimes between 1770 and 1840. Religious print, especially published association meeting notes and periodicals, extended the reach of itinerant preaching and molded a cross-border community in the Northeast Borderlands between 1790 and 1810. It allowed Baptists to discuss theology, share news about local churches, and expand their community. American Baptists formed international institutions focused on the spread of Protestantism after the War of 1812, and Maine Baptists actively engaged this more global community through financial donations to the new institutions …
