Loblolly Pine (Pinus Taeda) Leaf-Level Physiology And The Influence Of Genotype, Drought, And Thinning, Norman Jesse Cone Iv

Master's Theses

The Southeastern U.S. is known as the “Wood Basket” for producing the vast majority of U.S. timber, but projected increases in the frequency of severe drought events could threaten timber plantations. Loblolly pine (Pinus taeda) is the principle timber species of the southeast and is distributed across the Atlantic Coastal Plains and west into Texas. Western Gulf states (LA, TX, AR, and OK) lie at the edge of the range for loblolly pine and are particularly vulnerable to any changes in precipitation or temperature. Current research suggests two main methods to increase plantation drought resistance: plant drought resistant seedlings or …

Marketing Agroforestry Products: Lessons From Producers

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This publication shares producer experiences with marketing agroforestry products, including how producers entered — or created — the markets for their products. These individual stories highlight a diversity of experiences, from family-run farms to intermediaries assisting with market access. United States Department of Agriculture (USDA) and other federal, state, and local programs can provide capital or technical assistance to farmers at different phases of market development. The case studies in this publication highlight programs and resources available through USDA.

While marketing tree crops and non-timber forest products can be a challenge for producers, there is room for growth and opportunities …

Survey Of Ticks And Tick-Borne Pathogens Associated With Feral Swine (Sus Scrofa) In Arkansas, Haylee Campbell

Graduate Theses and Dissertations

Feral hogs (Sus scrofa L.) are an invasive species throughout the southeast United States and found in every Arkansas county. As feral hogs invade new habitat, they can disrupt ecosystems, damage agriculture systems, and bring ticks and tick-borne pathogens with them. There are no surveys of the tick species parasitizing the Arkansas feral hog populations or the pathogens they carry. This is a public health concern because feral hogs occupy often same geographical regions as humans and livestock and can harbor over 45 animal diseases and parasites. The ticks carried by feral hogs can carry tick-borne pathogens that can cause …

Sensitivity And Threshold Dynamics Of Pinus Strobus And Quercus Spp. In Response To Experimental And Naturally-Occurring Severe Droughts, Heidi Asbjornsen, Cameron D. Mcintire, Matthew A. Vadeboncoeur, Katie A. Jennings, Adam P. Coble, Z. Carter Berry

All Materials

Increased drought frequency and severity are a pervasive global threat, yet the capacity of mesic temperate forests to maintain resilience in response to drought remains poorly understood. We deployed a throughfall removal experiment to simulate a once in a century drought in New Hampshire, USA, which coupled with the region-wide 2016 drought, intensified moisture stress beyond that experienced in the lifetimes of our study trees. To assess the sensitivity and threshold dynamics of two dominant northeastern tree genera (Quercus and Pinus), we monitored sap flux density (Js), leaf water potential and gas exchange, growth, and intrinsic water use efficiency (iWUE) …

Pando's Lessons: Restoration Of A Giant Aspen Clone, Paul C. Rogers, Jody Gale, Darren Mcavoy

Aspen Bibliography

A 106 acre (43 ha) aspen clone lives in the Fishlake National Forest in south-central Utah. Clones are comprised of multiple aspen stems, called ramets, which are genetically identical. This particular colony of ramets was named “Pando” (Latin for “I spread”) by researchers believing it to be the largest living organism by mass on earth. Recently, forest managers have noted a rapid dying of mature stems without recruitment of younger trees. This unsustainable situation has galvanized restoration efforts at Pando. Human interventions caused this imbalance; restoration will rely on protection, monitoring, and innovation. As a laboratory, this forest icon may …

Analysis Of The White-Tailed Deer Population Of Hobbs State Park, Jesse Morrison

Biological and Agricultural Engineering Undergraduate Honors Theses

White Tailed deer (Odocoileus virginianus) are the only deer species native to Arkansas, playing a crucial role in the ecosystem. Healthy deer populations are important for environmental and human wellbeing, and overpopulation can lead to poor herd health, overgrazing, increased vehicle collisions, and transmission of diseases. Monitoring deer populations through surveys can be a useful tool in managing wildlife and maintaining Arkansas’ natural resources.

This study analyzed trends in Hobbs State Park’s deer population and estimated the current roadside deer population of the park. Data from past surveys was analyzed for trends using a Mann-Kendall Test, and a distance sampling …

Modeling Hydrochemical And Vegetation Responses Of High-Elevation Forested Watersheds To Future Climate And Atmospheric Deposition Changes In The Southeastern U.S., Hailong Huang

Dissertations

Changes in climate and atmospheric acidic deposition alter biogeochemical cycles in forested ecosystems. I investigated the responses of vegetation, soil, and hydro-related processes to changes in climate and acidic deposition at five high-elevation forests in the southeastern U.S. using a biogeochemical model - PnET-BGC model. I focused on change-points and thresholds concepts that were less studied in forest ecosystems as well as seasonal variability of responses and extreme events. I applied principal component analysis (PCA) to reduce the dimensionality of data. I developed a Bayesian multi-level model to derive key biogeochemical variables response to temperature and precipitation (local) and latitude …

Measuring Dynamic Changes In The Spatial Pattern And Connectivity Of Surface Waters Based On Landscape And Graph Metrics: A Case Study Of Henan Province In Central China, Bo Mu, Guohang Tian, Gengyu Xin, Miao Hu, Panpan Yang, Yiwen Wang, Hao Xie, Audrey L. Mayer, Yali Zhang

Michigan Tech Publications, Part 1

An understanding of the scientific layout of surface water space is crucial for the sustainable development of human society and the ecological environment. The objective of this study was to use land-use/land-cover data to identify the spatiotemporal dynamic change processes and the influencing factors over the past three decades in Henan Province, central China. Multidisciplinary theories (landscape ecology and graph theory) and methods (GIS spatial analysis and SPSS correlation analysis) were used to quantify the dynamic changes in surface water pattern and connectivity. Our results revealed that the water area decreased significantly during the periods of 1990–2000 and 2010–2018 due …

Modeling The Growth And Establishment Of Plantation And Converted Silvopasture Systems In The Missouri Ozarks Region, Stewart James Mccollum

Graduate Theses/Dissertations

The Missouri Ozarks are well known for high production in both timber products and cattle production. Most areas are also not well suited for many other agricultural practices such as row cropping, so forests and grazing lands dominate the landscapes. Such characteristics provide high potential for the agroforestry practice known as silvopasture. This study monitors the establishment of two different types of silvopasture systems, plantation and conversion types. In the plantation silvopasture, two cultivars of black walnut (Juglans nigra) were planted, Football and Kwikrop. Health and growth were monitored for those cultivars over the first year. The converted …

Understanding Water And Energy Fluxes In The Amazonia: Lessons From An Observation-Model Intercomparison, Natalia Restrepo-Coupe, Loren P. Albert, Marcos Longo, Ian Baker, Naomi M. Levine, Lina M. Mercado, Alessandro C. Da Araujo, Bradley O. Christoffersen, Marcos H. Costa, David R. Fitzjarrald

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Tropical forests are an important part of global water and energy cycles, but the mechanisms that drive seasonality of their land-atmosphere exchanges have proven challenging to capture in models. Here, we (1) report the seasonality of fluxes of latent heat (LE), sensible heat (H), and outgoing short and longwave radiation at four diverse tropical forest sites across Amazonia—along the equator from the Caxiuanã and Tapajós National Forests in the eastern Amazon to a forest near Manaus, and from the equatorial zone to the southern forest in Reserva Jaru; (2) investigate how vegetation and climate influence these fluxes; and …

Effects Of Prescribed Fire On Soil Respiration In A Longleaf Pine Forest., Caroline E. Paxton

Honors Theses

Prescribed fire is a common tool used to increase the herbaceous diversity in longleaf pine forest understories and to eliminate competition from undesirable mid-canopy species. Little is known about the effects of these fires on the soil respiration rates within these forests. A study of the effects of prescribed fire on soil respiration was conducted within a longleaf pine stand at the Lake Thoreau Environmental Center to examine soil respiration across seasons and before and after a prescribed fire. Soil CO₂ efflux rates were measured using a LICOR LI-8100A gas flux system with long-term chambers from October 2020 to …
