Eucalypts (Myrtaceae tribe Eucalypteae) are currently placed in seven genera. Traditionally, Eucalyptus was defined by its operculum, but when phylogenies placed Angophora, with free sepals and petals, as sister to the operculate bloodwood eucalypts, the latter were segregated into a new genus, Corymbia. Yet, generic delimitation in the tribe Eucalypteae remains uncertain. Here, we address these problems using phylogenetic analysis with the largest molecular data set to date. We captured 101 low-copy nuclear exons from 392 samples representing 266 species. Our phylogenetic analysis used maximum likelihood (IQtree) and multispecies coalescent (Astral). At two nodes critical to generic delimitation, we tested …

Non-Invasive Methods For Monitoring Weasels: Emerging Technologies And Priorities For Future Research, David S. Jachowski, Scott M. Bergeson, Stacy Cotey, Elizabeth Croose, Tim R. Hofmeester, Jenny Macpherson, Et Al.

Michigan Tech Publications, Part 2

Weasels (genus Mustela and Neogale) are of management concern as declining native species in some regions and invasive species in others. Regardless of the need to conserve or remove weasels, there is increasingly a need to use non-invasive monitoring methods to assess population trends. We conducted a literature review and held the first ever International Weasel Monitoring Symposium to synthesise information on historical and current non-invasive monitoring techniques for weasels. We also explored current limitations, opportunities, and areas of development to guide future research and long-term monitoring. Our literature search revealed that in the past 20 years, camera traps were …

Engagement For Life's Sake: Reflections On Partnering And Partnership With Rural Tribal Nations☆, Chelsea Schelly, Valoree Gagnon, Kathleen Brosemer, Kristin Arola 2024 Michigan Technological University

Engagement For Life's Sake: Reflections On Partnering And Partnership With Rural Tribal Nations☆, Chelsea Schelly, Valoree Gagnon, Kathleen Brosemer, Kristin Arola

Michigan Tech Publications, Part 2

In this paper, we reflect on our collective experiences engaging with Anishinaabe Tribal Nations in the Great Lakes region to support Tribal sovereignty in decision-making for food, energy, and water (FEW) systems. In these diverse experiences, we find common lessons. The first set of lessons contributes new empirical knowledge regarding the challenges and opportunities that rural Great Lakes Tribal Nations navigate for enacting sovereignty in decision-making. Our experiences illustrate that while Tribal Nations benefit from a broad and deep commitment to sovereignty and many cultural strengths, they are often challenged by shortages in administrative capacity; technical support; and embeddedness in …

Permafrost degradation in peatlands is altering vegetation and soil properties and impacting net carbon storage. We studied four adjacent sites in Alaska with varied permafrost regimes, including a black spruce forest on a peat plateau with permafrost, two collapse scar bogs of different ages formed following thermokarst, and a rich fen without permafrost. Measurements included year-round eddy covariance estimates of net carbon dioxide (CO2), mid-April to October methane (CH4) emissions, and environmental variables. From 2011 to 2022, annual rainfall was above the historical average, snow water equivalent increased, and snow-season duration shortened due to later snow return. Seasonally thawed active …

Drone flights were conducted over bobwhite individuals and coveys and information was collected on the date, time of flight, number of individuals estimated in the covey, and number of individuals flushed from the covey (i.e., actual number of individuals). We also report season of flight and the thermal sensor used for each flight. NA denotes that flush or capture was not attempted.

Mobilizing Indigenous Research Methodologies And Wabanaki Knowledge In Biophysical Research To Restore Wabanaki Sweetgrass Harvesting In Acadia National Park And Identify Basket Quality Black Ash Habitat For Emerald Ash Borer (Agrilus Planipennis) Preparedness, Suzanne Greenlaw 2023 University of Maine

Mobilizing Indigenous Research Methodologies And Wabanaki Knowledge In Biophysical Research To Restore Wabanaki Sweetgrass Harvesting In Acadia National Park And Identify Basket Quality Black Ash Habitat For Emerald Ash Borer (Agrilus Planipennis) Preparedness, Suzanne Greenlaw

Electronic Theses and Dissertations

Black ash (wikpiyik/Fraxinus nigra) and sweetgrass (suwitokolasol/Anthoxanthum nitens) are two culturally important species to Wabanaki (Passamaquoddy, Penobscot, Maliseet, Mi’kmaq, and Abenaki) people, and to many other Native American tribes across the species’ ranges. Wabanaki relationships with black ash and sweetgrass include creation stories, generational stewardship practices, important economic markets, and cultural identity. Land use patterns, changes in access, invasive species, and climate change are negatively affecting both the health of black ash and sweetgrass and Wabanaki people’s relationship to these species. This dissertation consists of five chapters that mobilize Wabanaki knowledge and address Wabanaki access to sweetgrass and an invasive …


Developing Novel Food Packaging Products With High Barrier Properties, Enabled By Cnf, Nabanita Das 2023 University of Maine

Developing Novel Food Packaging Products With High Barrier Properties, Enabled By Cnf, Nabanita Das

Electronic Theses and Dissertations

In recent times, plastic has become a highly favored choice for packaging due to its exceptional microbial, damage, and water-resistant properties. However, the alarming rise in plastic usage has led to adverse environmental pollution. This study aims to develop innovative food packaging solutions using renewable and compostable cellulose nanofibrils (CNFs). This thesis comprises two related studies on the barrier performance of novel food packaging materials, including oxygen barrier and oil/grease barrier properties. The goal of the first study was to enhance the mechanical and barrier properties of the cellulose nanofibril (CNF) films by inducing fibrils orientation for food packaging applications. …


Forest Management In A Changing Climate: Integrating Social And Biopysical Sciences To Inform Adaptive Responses To Future Uncertainty, Peter Breigenzer 2023 University of Maine

Forest Management In A Changing Climate: Integrating Social And Biopysical Sciences To Inform Adaptive Responses To Future Uncertainty, Peter Breigenzer

Electronic Theses and Dissertations

Forests provide numerous ecological and socio-economic benefits, yet climate change is creating novel and extreme conditions that threaten forests and disrupt traditional management practices. To address future uncertainty about how to manage forests amid a rapidly changing climate, researchers have developed adaptive management strategies that move away from using historical ecological baselines as management goals. However, despite increases in adaptive forest management frameworks, there are still concerns that private woodland owners (PWOs; also known as family forest owners or non-industrial private landowners) are not adopting beneficial practices. Additionally, since tree canopies often buffer understory microclimates (i.e., fine scale variation in …


Regeneration Response To Salvage Logging Following Tornado Disturbance, Colby K. Bosley-Smith 2023 University of Maine

Regeneration Response To Salvage Logging Following Tornado Disturbance, Colby K. Bosley-Smith

Electronic Theses and Dissertations

In an era of increasing natural disturbances, successful tree regeneration has grown more difficult to achieve. Salvage logging, a common management response to disturbance, may further impede regeneration success, although published literature currently remains inconclusive. In 2013, a rare tornado in northcentral Maine, USA, and subsequent salvage operation created three clear ‘treatments’ for evaluation of post-disturbance regeneration: blowdown, blowdown followed by salvage logging and an undisturbed control. In the summers of 2022 and 2023, (nine and ten) years post-tornado, we revisited this site to examine regeneration outcomes.

During the summer of 2022, we evaluated stand structure and regeneration success of …


Integrating Remote Sensing And Machine Learning To Assess Forest Health And Susceptibility To Pest-Induced Damage, Rajeev Bhattarai 2023 University of Maine

Integrating Remote Sensing And Machine Learning To Assess Forest Health And Susceptibility To Pest-Induced Damage, Rajeev Bhattarai

Electronic Theses and Dissertations

Spruce budworm (Choristoneura fumiferana; SBW) outbreaks are cyclically occurring phenomena in the northeastern USA and neighboring Canadian provinces. These outbreaks are often of landscape level causing impaired growth and mortality of the host species namely spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.). Acknowledging the recent SBW outbreak in Canadian provinces like Quebec and New Brunswick neighboring the state of Maine, our study devised comprehensive techniques to assess the susceptibility of Maine forests to SBW attack. This study aims to harness the power of remote sensing data and machine learning algorithms to model and map the susceptibility of …
