The Influence Of Environmental Variables On The Height Growth Of Loblolly Pine (Pinus Taeda) In The Western Gulf, Osakpamwan Edo-Iyasere
Electronic Theses and Dissertations
Understanding the effects of environmental factors on stand growth is important in optimizing forest management plans. This study investigated the effects of soil and climate factors on the height growth (site index) of loblolly pine (Pinus Taeda L.) using data collected from permanent plots established in intensively-managed plantations across East Texas and Western Louisiana. The Chapman-Richards model was selected as the base model to describe the height-age relationships and important soil and climate variables were incorporated into the models as model parameter coefficient adjustors. Our results showed that the most important factors for predicting site index were nitrogen …

Mammals Of Cedar Breaks National Monument, S. Nicole Frey, Natalie D'Souza, Ethan Hammer, Bryan Larsen, Jake Nielson
All Current Publications
This document is the result of a study of the terrestrial mammals found at Cedar Breaks National Monument from 2017-2019. During this time, we conducted a survey of mammals using a series of trail cameras. We used survey results to provide an index of terrestrial mammals (excluding bats) within the park. Our goal is to provide a beginner’s guide to the mammals at Cedar Breaks National Monument. We include information regarding appearance, diet, habitat, and population status according to the International Union for the Conservation of Nature (IUCN). The guide represents the species a visitor to Cedar Breaks National Monument …

Preliminary Flammability Assessment Of Sea Buckthorn From The Netherlands Compared To Known Flammable Shrubs Of The Southern And Western Us,

Preliminary Flammability Assessment Of Sea Buckthorn From The Netherlands Compared To Known Flammable Shrubs Of The Southern And Western Us, Michael Tiller, Brian P. Oswald, Mathijs Schuijn
Faculty Presentations
Sea buckthorn (Hippophae rhamnoides) is a common coastal species in The Netherlands that potentially burns with extreme energy levels. In this region of Europe that is experiencing increases in wildfire events, the need to gain a greater understanding of energy released when this species burns will improve fire behavior predictions. The objective of this study was to conduct an initial investigation into the foliage flammability of sea buckthorn to a common southern United States native shrub known for its flammability, yaupon (Ilex vomitoria), and two common dominant shrub species in California chaparral, chamise (Adenostoma fasciculatum …

The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
Theses and Dissertations from 2020
Insects are important in woodland ecosystems due to their role as pollinators and as prey for bats. My research investigated the relationships between forest management, vegetation, and insects in the Ozark National Forest in Arkansas. I selected 30 stands burned at varying frequencies in the last 12 years. Twelve of these stands were burned and mechanically thinned, 12 were only burned, and 6 were untreated. I deployed blacklight traps and malaise traps in each stand monthly from mid-March to mid- November 2019. Over 42,391 insects were collected, and Lepidoptera was the most abundant order. Insects were dried, weighed, and identified …

Ecology and Evolution published by John Wiley & Sons Ltd. The effects of climate change on tropical forests may have global consequences due to the forests’ high biodiversity and major role in the global carbon cycle. In this study, we document the effects of experimental warming on the abundance and composition of a tropical forest floor herbaceous plant community in the Luquillo Experimental Forest, Puerto Rico. This study was conducted within Tropical Responses to Altered Climate Experiment (TRACE) plots, which use infrared heaters under free-air, open-field conditions, to warm understory vegetation and soils + 4°C above nearby control plots. Hurricanes …

Carbon Sequestration In A Restored West Michigan Oak Savanna: Implications For Management Practices, Jeffrey A. Heise
Masters Theses
The savanna system is an ecosystem (i.e. a transitional ecosystem) that lies between forest and grassland ecosystems. They occur across the world in various forms, but in the North American Midwest they are specifically oak savannas: systems where the open overstory is dominated by various species of oak (Quercus spp.) and the understory consists of carbon-rich prairie grasses and forbs. This ecosystem is a highly degraded ecosystem and has lost almost 99% of its former range due to agriculture and fire suppression. Since savannas are fire-evolved systems, they are maintained by and require fire as a regular disturbance to …

Optimizing Species Selection For Forest Restoration In The Lower Rio Grande Valley, Faeqa Mohsin
Theses and Dissertations
Over the past four decades, the Lower Rio Grande Valley has been reforested with over 3.3 million native thornscrub plants in old agricultural land through transplanting native species. However, assessments of LRGV forest restoration efforts are scarce, and to address the knowledge gap, this study examined species-specific responses to restoration interventions (RIs) aimed at minimizing seedling mortality for optimizing species selection. A critical period for forest restoration in old croplands is the seedling stage, where high mortality occurs due to the interactive effects of abiotic stress, compromised soil nutrient status from intensive agriculture, and mammalian herbivory. So, we evaluated seedling …

Multiple Fgf4 Retrocopies Recently Derived Within Canids, Kevin Batcher, Peter Dickinson, Kimberly Maciejczyk, Kristin Brzeski, Sheida Hadji Rasouliha, Anna Letko, Cord Drögemüller, Tosso Leeb, Danika Bannasch

Two transcribed retrocopies of the fibroblast growth factor 4 (FGF4) gene have previously been described in the domestic dog. An FGF4 retrocopy on chr18 is associated with disproportionate dwarfism, while an FGF4 retrocopy on chr12 is associated with both disproportionate dwarfism and intervertebral disc disease (IVDD). In this study, whole-genome sequencing data were queried to identify other FGF4 retrocopies that could be contributing to phenotypic diversity in canids. Additionally, dogs with surgically confirmed IVDD were assayed for novel FGF4 retrocopies. Five additional and distinct FGF4 retrocopies were identified in canids including a copy unique to red wolves (Canis rufus). The …
