Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo

Aspen Bibliography

Data collected over a 30-year period from an experiment replicated across 21 locations in western Canada are used to explore the effects of precommercial thinning of trembling aspen to a range of densities in combination with three initial white spruce densities on tree growth and stand dynamics. Increasing differentiation amongst the 15 treatments was observed with age after thinning for both spruce and aspen responses. Spruce height and diameter declined with increasing aspen density. At age 10 spruce diameter with no aspen was 1.5× that of spruce in unthinned while it was 2.6× that of spruce in unthinned at age …

Tracing The Maternal Line In Glacial-Interglacial Migrations Of Populus Tremuloides: Finding Trees For Future Sustainable Forests By Searching In The Past, Luke R. Tembrock, Frida A. Zink, Guozhe Zhang, Andrea Schuhmann, Cuihua Gu, Zhiqiang Wu

Aspen Bibliography

Maintaining and planting sustainable forests is fundamental in perpetuating the essential functions of these ecosystems. A central aspect of managing forests for future resilience is the consideration of past migration and evolution of trees using genetic and genomic data to ensure that functionally appropriate diversity is conserved and utilized. In our study, we generated and compared genetic and genomic data from the plastome to better understand phylogeography and molecular evolution in the tree species Populus tremuloides (aspen). With these analyses, we found evidence of divergence and migration between northern and southern sites. Additionally, evidence of deep incomplete plastome sorting across …

Perianth Evolution And Implications For Generic Delimitation In The Eucalypts (Myrtaceae), Including The Description Of The New Genus, Blakella, Michael D. Crisp, Bui Q. Minh, Bokyung Choi, Robert D. Edwards, James Hereward, Carsten Kulheim, Yen Po Lin, Karen Meusemann, Andrew H. Thornhill, Alicia Toon, Lyn G. Cook

Michigan Tech Publications

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

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 …

Dynamics Of Soil Microbial Communities Involved In Carbon Cycling Along Three Successional Forests In Southern China, Minghui Hu, Shuyidan Zhou, Xin Xiong, Xuan Wang, Yu Sun, Ze Meng, Dafeng Hui, Jianling Li, Deqiang Zhang, Qi Deng

Biology Faculty Research

Dynamics of plant communities during forest succession have been received great attention in the past decades, yet information about soil microbial communities that are involved in carbon cycling remains limited. Here we investigated soil microbial community composition and carbohydrate degradation potential using metagenomic analysis and examined their influencing factors in three successional subtropical forests in southern China. Results showed that the abundances of soil bacteria and fungi increased (p ≤ 0.05 for both) with forest succession in relation to both soil and litter characteristics, whereas the bacterial diversity did not change (p > 0.05) and the fungal diversity of Shannon-Wiener index …

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

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 …

The Long-Term Effects Of Prescribed Fire On Floral Abundance And Bumble Bee Abundance In Mixed-Oak Forests Of Southeastern Ohio, Moses Shafer

Theses, Dissertations and Capstones

Pollinators are declining due to climate change and habitat loss driven by agriculture and urbanization. In fire-adapted ecosystems, fire promotes the biodiversity of plants by creating space, reducing competition, and increasing light and nutrient availability. However, little is known regarding the effects of fire on floral abundance of plants used by Bombus. The overall goal of this project was to assess the long-term effects of fire on floral abundance and Bombus abundance. Our specific questions were: (1) How does fire frequency influence floral abundance?, (2) How does fire frequency influence floral abundance of species specifically utilized by bumble bees?, …

Habitat loss due to deforestation is a primary threat to global biodiversity. Clearing tropical rainforests for agriculture leads to forest fragmentation. Forest fragments contain fewer large trees and provide lower food availability for primates compared to continuous forests. Mantled howler monkeys inhabit the increasingly fragmented rainforests of Central and South America and may need to alter their activity and spatial cohesion to mitigate competition and preserve energy in fragments where there is lower quality food. We compared howler monkey activity and spatial cohesion across a small forest fragment (La Suerte Biological Research Station, LSBRS) and a large, continuous forest (La …

Human wildlife interactions (HWI) pose a complex challenge for wildlife managers. Human encroachment into wildlife habitat and the growing number of outdoor recreationists are increasing the frequency of contact and conflict, especially in regions such as the Front Range of Colorado. Geographic information systems (GIS), which use a combination of remote sensing and environmental survey data, allow for predictive spatial analyses of where human wildlife interactions are likely to occur. I used publicly reported observations of moose to create spatial predictive maps in a species distribution model framework. Slope and elevation were shown to be the strongest predictors of HWI, …

Short-Term Impacts Of Biochar And Mycorrhizal Inoculation For Pinus Echinata Reforestation On Strip-Mined Soils, Casey Iwamoto, Courtney Siegert, Joshua J. Granger, Adam Polinko, Krishna P. Poudel, Zachary Freedman

FWRC Publications

Coal strip mining has left widespread degraded soils throughout the southeastern US. These soils tend to have low pH, high bulk density, impacted hydrologic processes, and an accumulation of heavy metals that limit revegetation efforts. Shortleaf pine (Pinus echinata) is an ideal species for these reforestation efforts as it can tolerate the poor conditions on post-mined sites and has the largest native pine range in the southeastern US, overlapping with many post-mined areas. However, limited empirical field studies have been conducted on the success of soil amendments for soil physical, chemical, biological properties and tree growth. To fill …

Effects Of Climate Change On Seed Germination May Contribute To Habitat Homogenization In Freshwater Forested Wetlands, Kori Carr, Xavier Ozowara, Taylor M. Sloey

Biological Sciences Faculty Publications

Climate changes in temperate regions are expected to result in warmer, shorter winters in temperate latitudes. These changes may have consequences for germination of plant species that require a period of physiological dormancy. The effect of cold duration on seed germination has been investigated in a number of plant taxa, but has not been well studied in wetland and bottomland forest tree species, an ecosystem that is threatened by habitat homogenization. Our work sought to test the role of changing winter temperatures on seed germination in specialist (Nyssa aquatica and Taxodium distichum) and generalist (Acer rubrum and Liquidambar styraciflua) tree …

Longevity Of Prescribed Fire Effectiveness In Mixed-Evergreen Forests Of The Klamath Mountains, Kaily M. Fineran

Cal Poly Humboldt theses and projects

Prescribed fire is a common management tool used across the western United States to create wildfire-resilient ecosystems and communities. The Klamath Mountains of northern California, USA has experienced numerous, large wildfires in recent years. This is due in part to a combination of highly flammable fuels, uncharacteristic weather events, and high fuel accumulations as a result of fire exclusion and forest management practices. Within the last decade, local land management organizations and the Karuk Tribe have begun re-introducing prescribed fire in low elevation, mixed evergreen forests. While the long-term effects of fuel treatments are not well-known, these efforts provided a …

Post-Fire Persistance Of Sequoia Semperviens In A Secondary Forest: Examining Drivers Of Basal Resprouting Response, Jackson T. Carrasco

Cal Poly Humboldt theses and projects

Historically frequent-fire forest ecosystems are now facing increased size, frequency, and severity of fires attributed to climate change, intensive forest management, and fire exclusion. Understanding post-fire resilience in forest ecosystems is critical amidst escalating challenges posed by recent increases in fire activity. This study examined the basal resprouting response of coast redwood (Sequoia sempervirens) in a secondary forest two years after the CZU Lightning Complex fire on the central coast of California. Robust allometric equations were developed to quantify redwood resprout biomass and leaf area, revealing strong explanatory power for biomass equations (R² > 0.85). Probability of …

Satellite-Based Phenology And Climate Anomaly Analysis In Evaluating The Response Of Puerto Rico And The U.S. Virgin Islands Tropical Forests To The 2015-2016 Drought, Sean Fleming

Cal Poly Humboldt theses and projects

The health and overall resilience of tropical forest ecosystems are closely tied to the timing of phenological events. One must consider how forests react to significant climate anomalies to forecast the possible effects of climate change. This research study utilized U.S. Forest Service Forest Inventory Analysis (FIA) plot-level data and Landsat satellite data together to determine if these datasets are valuable techniques to understand the impacts of the 2015-2016 drought on Puerto Rico and the U.S. Virgin Islands (PRVI). I did remote sensing analysis on PRVI to produce repaired and near cloud-free satellite imagery, producing dozens of phenometrics of all …

Spatiotemporal Patterns For Agroforestry Tree Crops In The U.S. Corn Belt For Usda Census Of Agriculture Periods 2012–2022, Andria Caruthers, Justin Dijak, Robin M. Rotman

Faculty Publications

Within the U.S., there is a growing need to integrate environmentally friendly practices into conventional agriculture. Agroforestry enhances environmental and resource stewardship in agricultural landscapes while offering potential economic benefits to farmers. Despite rising interest, limited information on its application in the U.S. hinders development efforts. A spatiotemporal analysis of current farm operations can provide crucial insights. This study examined patterns of agroforestry and tree crop adoption in the U.S. Corn Belt using USDA Census data (2012, 2017, and 2022) and spatial tools (Global Moran’s I, Local Moran’s I, and Moran scatterplots). The tree crops included in the analysis were …

Forensic Archaeology Protocols for Wildfires and Fire-Related Scenes

Forensic archaeology is a relatively new area of study and focuses on the medical legal aspects of archaeology. This paper will focus on how forensic archaeology should be used for wildfire and other fire-related fatalities or investigations, what happens to bone when exposed to heat, what protocols should be in place and how an excavation should look, and finally the challenges of fire-related investigations. This report will focus on the larger scale of the investigation and will be using several sources from different wildfire and fire fatality reports.
