Earthworm And Soil Data For Ottawa National Forest, Blair Orr

Michigan Tech Research Data

Two types of analysis were run.

I. Probability of finding L. terrestris in habitat types of the Ottawa National Forests.

Abstract: Parts of the Ottawa National Forest (ONF) provide suitable habitat for invasive earthworms. Extensive earthworm invasion is a relatively recent event on the ONF and this study captures the current state of the earthworm invasion through a four-stage invasive species distribution model (iSDM). The random distribution of earthworms indicates early colonization by earthworms which is moderated by habitat (forest type, soil group, and drainage class). CART modeling was used to determine probability of earthworm invasion. The CART model had …

Comparing Allelochemicals Of ​English Ivy And Native Georgia Plants​, Rebecca Senft

Symposium of Student Scholars

English Ivy (Hedera helix L.) is a common invasive plant causing biodiversity losses across the southeast and parts of the northwestern US. The mechanisms by which Ivy invades native ecosystems are not well understood but may include allelopathy, a process through which one species produces biochemicals that disrupt competitors. These biochemicals are often produced and exuded by roots into soil, making them difficult to isolate. This study used a soil-less hydroponic system and gas-chromatography mass spectroscopy to examine differences in the chemicals produced by roots of native Georgia plants and English Ivy. Our results suggest there are differences in the …

Making Agriculture Carbon Neutral Amid A Changing Climate: The Case Of South-Western Australia, Ross Kingwell

Climate Science Research Articles

Making Australian agriculture carbon neutral by 2050 is a goal espoused by several agricultural organisations in Australia. How costly might it be to attain that goal, especially when adverse climate change projections apply to agriculture in southern Australia? This study uses scenario analysis to examine agricultural emissions and their abatement via reforestation in south-western Australia under projected climate change. Most scenarios include the likelihood of agricultural emissions being reduced in the coming decades. However, the impact of projected adverse climate change on tree growth and tree survival means that the cost of achieving agricultural carbon neutrality via reforestation is forecast …

Modeling Environmental Factors Related To Drought-Induced Tree Mortality Based On Lidar And Hyperspectral Imagery, Lauren Nicole Sharwood

Dissertations and Theses

Climate change is projected to bring more frequent and prolonged droughts, causing widespread forest die-off. Identifying tree mortality over large spatial extents in response to the most recent California drought will help forest managers and conservationists understand where there may be a greater likelihood of future die-offs. In order to find more at-risk areas, this study evaluated how interacting site-specific topographic, climate, substrate, and stand characteristics mediated tree mortality in the Central Sierra Nevada during the 2012-2016 drought. The author used lidar and hyperspectral imagery provided by the National Ecological Observatory Network to identify individual dead trees using the Random …

Willingness Of Non-Industrial Private Forest Landowners To Obtain A Private Versus Public Consultation, Erika Largacha

LSU Master's Theses

Promoting conservation practices among family forests landowners play a critical role to enhance forest health and ecosystem services. Several certification programs recognize such efforts, but participation among landowners varies based on their characteristics, program requirements, and incentives. One crucial step of certification is to obtain a forest management plan, but acquisition among landowners remains extremely low. Several studies suggest connecting landowners with foresters as the key element towards the adoption of forest management plans. Because foresters are typically employed by public forestry agencies or as private self-employed consultants, landowners' willingness to work with either may differ. As far as we …

Sampling Bias Exaggerates A Textbook Example Of A Trophic Cascade, Elaine M. Brice, Eric J. Larsen, Daniel R. Macnulty

Aspen Bibliography

Understanding trophic cascades in terrestrial wildlife communities is a major challenge because these systems are difficult to sample properly. We show how a tradition of non-random sampling has confounded this understanding in a textbook system (Yellowstone National Park) where carnivore [Canis lupus (wolf)] recovery is associated with a trophic cascade involving changes in herbivore [Cervus canadensis (elk)] behaviour and density that promote plant regeneration. Long-term data indicate a practice of sampling only the tallest young plants overestimated regeneration of overstory aspen (Populus tremuloides) by a factor of 4–7 compared to random sampling because it favoured plants taller than the preferred …

Fuel Inventory Report For Montana De Oro State Park, Spencer Gordon

Master of Science in Environmental Sciences and Management Projects

Within the last century anthropogenic effects have shifted fire resilient habitats that are adapted to thousands of years of frequent low intensity fires to landscapes that are susceptible to extreme fire behavior which threaten human assets and sensitive natural resources. Entities that manage forests will need to prioritize fuel reduction as a management tool to promote forest health and mitigate hazardous fire conditions. A fuel inventory of a eucalyptus forest at Montana De Oro State Park in Los Osos, CA was collected using a combination of Brown’s 1973 and Brown’s 1982 methods. The fuel inventory revealed the eucalyptus forest yielded …

Genome-Wide Snp Identification In Fraxinus Linking Genetic Characteristics To Tolerance Of Agrilus Planipennis, Cecelia E. Hale, Mark A. Jordan, Gloria Iriarte, Kirk Broders, Andrew J. Storer, Vamsi J. Nalam, Jordan M. Marshall

Michigan Tech Publications, Part 1

Ash (Fraxinus spp.) is one of the most widely distributed tree genera in North America. Populations of ash in the United States and Canada have been decimated by the introduced pest Agrilus planipennis (Coleoptera: Buprestidae; emerald ash borer), having negative impacts on both forest ecosystems and economic interests. The majority of trees succumb to attack by A. planipennis, but some trees have been found to be tolerant to infestation despite years of exposure. Restriction site-associated DNA (RAD) sequencing was used to sequence ash individuals, both tolerant and susceptible to A. planipennis attack, in order to identify single nucleotide polymorphism (SNP) …

Planning For Future Fire: Scenario Analysis Of An Accelerated Fuel Reduction Plan For The Western United States, Alan A. Ager, Cody Evers, Michelle A. Day, Fermin J. Alcasena, Rachel Houtman

Environmental Science and Management Faculty Publications and Presentations

Recent fire seasons brought a new fire reality to the western US, and motivated federal agencies to explore scenarios for augmenting current fuel management and forest restoration in areas where fires might threaten critical resources and developed areas. To support this effort, we modeled the scheduling of an accelerated forest and fuel management scenario on 76 western US national forests. Specifically, we modeled a 10-year ramp up of current forest and fuel management that targeted the source of wildfire exposure to developed areas and simulated treatment in areas that accounted for 77% of the predicted exposure. We used a sample …

Climate Change Is Driving Greening Trend Whereas Tree Cover Is Declining In The Western Himalaya Of Pakistan, Arshad Mahmood Khan, Nadia Khalid

Journal of Bioresource Management

Recent studies suggest that two factors including climate change (especially precipitation) and human land use management (HLUM) are primarily driving greening trend around the world. However, studies targeting the impact of both factors on different vegetation layers (i.e. herbs, shrubs and tree layers) are lacking. This study hypothesize that precipitation relatively influence the under-storey vegetation cover more quickly, and HLUM (say afforestation/reforestation, deforestation) is more important towards top-storey layer. To investigate this, 13 randomly selected permanent stations in the wild natural west Himalayan coniferous forests of Sudhan Gali, Pakistan were explored from 2000-2016 to collect vegetation health data by two …

Water Requirements For Growth And Survival Of Swietenia Macrophylla And Tabebuia Heterophylla Juvenile Trees In Relation To Water Production Capacity Of Dew Condensers1, Jodelin Seldon, Victor A. Snyder, Eric Harmsen, Skip Van Bloem

Publications

Drought mortality of juvenile trees is a major cause for failure of reforestation projects. Portable devices such as passive radiative dew condensers can often provide 0.15 L/day of water in situ, possibly sufficient for tree survival until roots can access groundwater, allowing self-sustainability. To evaluate growth and survivability of juvenile trees of Tabebuia heterophylla Britton and Swietenia macrophylla King under such low water amounts, juvenile trees received approximately 0.033, 0.067, 0.134, 0.201 and 0.268 L/tree/day, representing fractions (relative evapotranspiration or RET) of 0.125, 0.25, 0.50, 0.75 and 1.00 of the evapotranspiration demand (ETo). The experiment lasted 60 days for S. …

Investigating The Impact Of Land Use On Avian Diversity And Abundance In Areas Surrounding Mabamba Swamp, Uganda, Sydney Marie Jones

Independent Study Project (ISP) Collection

The primary objective of this study was to investigate the impact of wetland-adjacent land use on avian species richness and abundance areas surrounding Mabamba Swamp, Uganda. Four types of land use were investigated: Eucalyptus plantations, wetland-edge agricultural fields, residential areas, and mature secondary forests. A total of 40-morning point counts were conducted for ten days in late November and late December of 2021. One-way ANOVA tests and Tukey’s HSD tests revealed significant differences in mean avian richness and abundance between all sites except residential areas and Nkima Forest. Additionally, Nkima Forest was found to contain the most number of specialist …
