Assessing The Potential For Bigleaf Maple Syrup Production In Humboldt County, Ca, David A. Reinhart, Juan A. Ramos-Cool, Liam H. Richardson
Undergraduate Scholarship
The bigleaf maple (Acer macrophyllum, Pursh) is the largest maple of the Pacific Northwest. While it has generally been treated as a nuisance in timber harvesting operations, a small amount of research has been conducted on its sugaring ability in Oregon, Washington, and British Columbia. This research has yet to reach further south in the species' range. This study aims to help a California landowner understand which maple trees on his property produce the most maple sap, to gauge what environmental factors contribute to maple sap production, and to find greater implications for the production of maple sap …

Huchum: The Legacy Of Fire Suppression, Indigenous Land Management, And Media Representation, Carolyn Coyne
Pomona Senior Theses
In my thesis, I examine how various forms of news media from the 1900s to present day in Ohlone territory have framed a particular hegemonic ideology around fire that matches early colonial journal entries – an ideology that is fueled by fear, sensationalism, and exclusion and directly commits violence against the Ohlone people. I investigate this time period because this is when modern news corporations, like The New York Times, rose into prominence. Specifically, I question how media representations of fire inform regulations over controlled burns; what are the similarities in discourse between media framing and policy? What tactics are …
How Forest Stand Conditions Influence Whitebark Pine And Clark’S Nutcracker: A Systematic Review,

How Forest Stand Conditions Influence Whitebark Pine And Clark’S Nutcracker: A Systematic Review, Bryan Mathew Cohen
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Whitebark pine (Pinus albicaulis), a keystone species of high-elevation ecosystems of western North America, is threatened with extinction due to disease (Blister rust), pests (Mountain pine beetle), and climate change. Regeneration of the species depends nearly exclusively on the seed-caching behavior of Clark’s nutcracker (Nucifraga columbiana, Family Corvidae). Because of this, conservation of whitebark ecosystems requires restoring stand structures that favor nutcrackers. Although there are increasing numbers of studies on the relationship between nutcrackers and whitebark pine, findings have not yet been synthesized, limiting knowledge for application to management. I did a systematic literature review to answer the following questions: …

University of Kentucky
Predicting Patterns Of Species Presence In Eastern Kentucky Using Fine- And Broad-Scale Site-Species Relationships, Kyra L. Shrout
Theses and Dissertations--Forestry and Natural Resources
Understanding site-species relationships is integral to effective forest management, as landscape factors influence both the presence of mature trees and the regeneration of future trees. This study examined the influence of topographic, soil, and canopy variables on species presence at both fine (i.e., stand-level) and broad (i.e., forest-wide) scales within Robinson Forest, Kentucky. At the fine-scale, using vegetation data from permanent sampling plots, LiDAR-derived topographic data, and historical soils data, the relationships between the species of interest and the landscape variables within a single watershed were analyzed using conditional inference tree (CTree) models. Elevation and slope aspect were the most …

Initial Fungal Decomposer Community Determines Wood-Derived Carbon In Discrete Soil Carbon Pools In Aspen Clearcuts, Theresa K. Meyer
Dissertations, Master's Theses and Master's Reports
Soil carbon storage can be affected by forest management activities that alter the amount of biomass at a site, including slash retention and salvage harvesting. Initial fungal colonization of retained biomass may affect soil carbon storage due to differences in fungal decomposition strategies. To examine the effect of wood addition on wood-derived soil carbon storage and the interaction between initial fungal decomposer communities and wood application depth, δ13C modified wood inoculated with white- or brown-rot fungi was applied to soils across Michigan’s Upper Peninsula. Wood-derived carbon was assessed after 3.5 years in bulk soil samples and in three …

Impacts Of Southern Pine Beetle (Dendroctonus Frontalis Zimmerman) On Loblolly Pine (Pinus Taeda L.) Canopy And Water Use In The Homochitto National Forest, Mississippi, Usa, Sasha Goodnow, Yun Yang, Hui Liu, Ashley Schulz
Endeavors: Mississippi State Undergraduate Research Journal
Abiotic and biotic forest disturbances can have many impacts to forest ecosystem services, including to forest water use. Studies on impacts to forest evapotranspiration have been conducted on the mountain pine beetle (Dendroctonus ponderosae) in western North America, but not on the southern pine beetle (Dendroctonus frontalis), which is a native pest of loblolly pine (Pinus taeda) and shortleaf pine (Pinus echinata), in the southeastern United States. Stressed pine trees produce pheromones that attract southern pine beetles and, with enough stressed trees, beetle populations can quickly grow to epidemic levels and attack healthy trees, which results in widespread tree mortality. …

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn
Journal of Earth and Life Science
How white-tailed deer use the landscape in an urban environment can help us understand the effects of urbanization on deer populations. White-tailed deer form observable matriarchal hierarchies in studied populations. This study examines the matriarchal structure, home range size, and home range composition of 25 collared white-tailed deer within the city limits of Bemidji, MN. The results found no significant difference between age class and home range size or composition. However, movement metrics from yearling and mature age classes were more similar than the juvenile age class females. I propose this is because social acceptance between mature females was higher …
Tree Crown Economics Of Broadleaf Deciduous Forests,

West Virginia University
Tree Crown Economics Of Broadleaf Deciduous Forests, Yiting Fan
Graduate Theses, Dissertations, and Problem Reports (ETD)
Tree crown architecture, a critical determinant of forest ecosystem processes such as photosynthesis, evapotranspiration, and spectral reflectance, is shaped by adaptive trade-offs in resource use and environmental responses. However, significant gaps remain in our understanding of how these traits vary across species, environmental gradients, and temporal scales. This dissertation addresses these gaps by employing remote sensing data across three interconnected studies. Together, these studies advance tree crown economic theory, highlighting how crown traits mediate trade-offs between light capture and water-use efficiency and how these traits influence forest responses to global change. Collectively, this dissertation offer insights for improving models that …

Balancing Timber Harvest And Biodiversity: Impacts Of Selective Logging On Wildlife In The Chiquibul Forest Reserve, Belize, Kilynn Groen
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Selective logging is often promoted as a sustainable forestry practice that maintains biodiversity and ecosystem function, yet its ecological consequences remain under examined, particularly in tropical forests. This study investigates how selective logging affects wildlife communities in the Chiquibul Forest Reserve, Belize. Using remote camera trap data from 22 sites (9 unlogged forest sites and 13 logged (stump) sites), we assessed species richness, trophic structure, and environmental predictors of wildlife abundance. While overall wildlife captures and species richness did not differ significantly between forest and stump habitats, principal component analysis revealed strong community-level separation, with stump habitats supporting distinct species …

Herpetofauna Richness, Diversity, And Occurrence At The Northern Ecotone Of Longleaf Pine, Julianne Jones, Dylan Bryant, Erik Yando
Biological Sciences Faculty Publications
Habitat suitability commonly differs between the core and periphery of ecosystems. The longleaf pine ecosystem is recognized for its value in providing habitat to a variety of specialist and endemic species, especially herpetofauna. However, at the northernmost extent of longleaf pine (in southeastern Virginia) little is known about the denizen reptiles and amphibians. Moreover, the remaining longleaf pine ecosystem at the latitudinal ecotone is fragmented amongst a mosaic of other ecosystems. We examined herpetofauna diversity, richness, and capture rates between four focal habitat types—mature longleaf pine, restored longleaf pine, maple-gum swamp, and pocosin-bog—in the Zuni Pine Barrens of southeastern Virginia. …
