Perceptions Of Historical Climate Change And Park Policy: The Impact On The Fremont Cottonwood In Zion National Park, Kathleen Kavarra Corr

Doctoral Dissertations

Despite its “natural” appearance and the Organic Act 1916 mandate for preservation of the natural environment in National Parks, the Virgin River as it flows through Zion National Park’s Zion Canyon was transformed through massive flood control re-engineering projects in the 1930s. The armoring of the river has had significant impacts on riparian vegetation, particularly on the stands of native Fremont Cottonwood trees that once filled the narrow valley. What was the motivation for this massive flood control project carried out in an arid region with less than 15 inches of rain per year?

This dissertation explores the motivations which …

Assessment Of The Economic And Ecosystem Service Contributions Of Usda Forest Service Landowner Assistance Programs In The Conterminous United States, Jacqueline S. Dias

Masters Theses

Forests provide immense goods and services to both local and regional communities. The USDA Forest Service’s, State and Private Forestry program administer multiple landowner assistance programs aimed at helping private forest owners while supporting the continued supply of ecosystem services (e.g., timber harvesting, recreation, carbon sequestration and storage). The two landowner assistance programs assessed in this study are the Forest Legacy Program (FLP) and the Forest Stewardship Program (FSP). A majority of the nation’s forests are privately owned, many of which are facing deleterious impacts like wildfires, invasive species, development pressures, and other adverse effects from climate change. The goal …

The Study Of Tree Biomass Calculation By Comparing Partial Harvest Method With The Allometric Equations Method, Kanlayarat Jantawong, Titinan Pothong

Journal of Bioresource Management

This study aimed to investigate the effective of partial harvest method used for tree biomass estimation. Such method was analyzed for the correlation in compare with invented allometric equations. The advantages and disadvantages of those methods were discussed. The significantly difference between estimation methods were analyzed. As a result, tree biomass calculated by the Brown’s allometric equation produced highest results, followed by the partial harvest method, Tsutsumi’s, Chave’s and Pothong’s equations respectively. The selected allometric equations showed the positive correlation with partial harvest method. The highest positive correlation was found between the partial harvest method and both equation of Chave …

Disturbance Reduces Fungal White-Rot Litter Mat Cover In A Wet Subtropical Forest, D. Jean Lodge, Ashley E. Van Beusekom, Grizelle González, Mareli Sánchez-Julia, Sarah Stankavich

USDA Forest Service / UNL Faculty Publications

Fungi that bind leaf litter into mats and produce white-rot via degradation of lignin and other aromatic compounds influence forest nutrient cycling and soil fertility. Extent of white-rot litter mats formed by basidiomycete fungi in Puerto Rico decreased in response to disturbances—a simulated hurricane treatment executed by canopy trimming and debris addition in 2014, a drought in 2015, a treefall, and two hurricanes 10 days apart in September 2017. Percent fungal litter mat cover ranged from 0.4% after Hurricanes Irma and Maria to a high of 53% in forest with undisturbed canopy prior to the 2017 hurricanes, with means mostly …

Eight-Year Regeneration Response To Gap-Based Irregular Shelterwood Practices In Oak Dominated Stands Near Berea, Kentucky, Brooke Elizabeth Gauthier

Theses and Dissertations--Forestry and Natural Resources

This research examined regeneration dynamics following gap-based irregular shelterwood practices in intermediate productivity oak (Quercus)-dominated stands located in Berea College Forest, Berea, KY, USA. Established in 2012, the study includes 12 experiment units comprising a circular harvest gap (30 m radius) and a matrix zone delineated around the circumference of the gap, which extended 30 m from the gap edge into the adjacent forest. A midstory removal treatment was performed within six of the experiment units’ matrices, while six matrices were left untreated (control). Belt transects extending 60 m from gap center to the end of the matrix zone were …

Rna Interference For Emerald Ash Borer Suppression: Ecotoxicological Assessment And Delivery Methods, Flavia Pampolini

Theses and Dissertations--Entomology

The emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), is a highly invasive phloem-feeding insect native to Asia. It has killed millions of ash trees (Fraxinus spp.) since its accidental introduction into North America, causing profound economic and ecological impacts. RNA interference (RNAi) or double-stranded RNA (dsRNA)-mediated gene silencing is an emerging biotechnology that is developing as an innovative tool for pest management. Exogenous dsRNA triggers the RNAi pathway, silences genes, and disrupts protein function, causing insect mortality. RNAi has proven effective in reducing target gene expression and causing mortality in EAB; however, two aspects stand as barriers …
