The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

Wildland Fire Deficit And Surplus In The Western United States, 1984-2012, Sean A. Parks, Carol Miller, Marc-Andrè Parisien, Lisa M. Holsinger, Solomon Z. Dobrowski, John Abatzoglou

Forest Management Faculty Publications

Wildland fire is an important disturbance agent in the western US and globally. However, the natural role of fire has been disrupted in many regions due to the influence of human activities, which have the potential to either exclude or promote fire, resulting in a "fire deficit" or "fire surplus," respectively. In this study, we developed a model of expected area burned for the western US as a function of climate from 1984 to 2012. We then quantified departures from expected area burned to identify geographic regions with fire deficit or surplus. We developed our model of area burned as …

Why Add Edible And Floral Plants To Riparian Forest Buffers?

Working Trees (USDA-NAC)

Why add edible and floral plants to riparian forest buffers?

Multifunctional riparian forest buffers (MRFBs) offer the opportunity to produce perennial crops of native fruits and nuts, as well as floral trees and shrubs.

Research Notes Lower Prairie Creek Project Redwood National Park, Susie Van Kirk

Susie Van Kirk Papers

Project Description: to conduct Phase 1 of a narrative history project for the Lower Prairie Creek Watershed, funded by Save the Redwoods League. Phase1 of this project will be to compile reference materials, sources, conduct scoping with NPS staff and other local stakeholders to develop historical research themes that will be needed for a future narrative history of the Lower Prairie Creek Watershed. It will result in a detailed chapter outline to be submitted to NPS.

Mycorrhizal Roots In A Temperate Forest Take Up Organic Nitrogen From 13c- And 15n-Labeled Organic Matter, Matthew A. Vadeboncoeur, Andrew P. Ouimette, Erik A. Hobbie

All Materials

Background and Aims

The importance of the uptake of nitrogen in organic form by plants and mycorrhizal fungi has been demonstrated in various ecosystems including temperate forests. However, in previous experiments, isotopically labeled amino acids were often added to soils in concentrations that may be higher than those normally available to roots and mycorrhizal hyphae in situ, and these high concentrations could contribute to exaggerated uptake.

Methods

We used an experimental approach in which we added ¹³C-labeled and ¹⁵N-labeled whole cells to root-ingrowth cores, allowing proteolytic enzymes to release labeled organic nitrogen at a natural rate, as …

Prey Size And Dietary Niche Of Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii), Luke E. Dodd, Michael J. Lacki, Joseph S. Johnson, Lynne K. Rieske

Forestry and Natural Resources Faculty Publications

Bats in the genus Corynorhinus possess a suite of morphological characters that permit them to effectively use both gleaning and aerial-hawking foraging strategies to capture Lepidoptera. Consequently, they occupy a specialized feeding niche within North American bat assemblages and are of particular interest for dietary studies. We collected fecal pellets from a colony of C. rafinesquii (Rafinesque's Big-Eared Bat) at Mammoth Cave National Park during August–October 2011 and amplified cytochrome-c oxidase subunit 1 fragments of prey from these pellets. We used the Barcode of Life Database to identify prey, and evaluated the size of prey species based on published values. …

Demography And Disease Of The Rare Shrub Buckleya Distichophylla (Santalaceae) In Northeastern Tennessee, William Seth Ratliff

Undergraduate Honors Theses

Piratebush (Buckleya distichophylla (Nutt.) Torr.) is a rare, hemiparasitic shrub with the only extant populations in western North Carolina, northeastern Tennessee, and southwestern Virginia. The preferred natural hosts of piratebush, Carolina and eastern hemlocks, have seen sharp declines over the last decade due to the invasive hemlock woolly adelgid. Virginia pine, another important host of piratebush, is also susceptible to disease, specifically Cronartium appalachianum, a rust fungus for which piratebush is the secondary host. This study described and analyzed current demographic parameters of three Tennessee piratebush populations. Additionally, spatial patterns of disease and demographic characters were analyzed. These …

Centerville Slough Project, Susie Van Kirk

Susie Van Kirk Papers

An extensive cultural resources document for the Eel River Estuary Preserve was prepared in 2014 to identify resources within the initial project area. With new project proposals and an expanded Area of Potential Effect (APE), several additional structures were surveyed. This addendum looked at three barns and a house, none of which will be affected by proposed projects. They were surveyed because they fall within the expanded APE.

Some of the research conducted for the 2014 historic resources document was applicable to the addendum, including land ownerships and newspaper references. For the present report, additional research was conducted in the …

Southeastern Monochamus And Their Interactions With Healthy Shortleaf Pine Trees And Associated Ips Grandicollis Bark Beetles, Matthew Walker Ethington

Graduate Theses and Dissertations

Insects in the genus Monochamus are medium to large-sized, wood-boring beetles whose primary hosts in the Northern Hemisphere are pine trees. These beetles interact with both conifer hosts and associated insects throughout their life history. Past research has demonstrated that Monochamus are saprophagic, but recent findings show that they may colonize healthy pine trees. To determine if southeastern Monochamus could colonize healthy pines, adult Monochamus were attracted to healthy shortleaf pine trees from May to September, 2014, using host volatiles, Ips bark beetle kairomones, and congeneric pheromones. Subsequent development of oviposited eggs from 18 host trees was monitored. The results …

Chinese Tallow Invasion In Maritime Forests: Understand Invasion Mechanism And Develop Ecologically-Based Management, Lauren Susan Pile

All Dissertations

Invasion by highly aggressive, non-native, invasive plants is a significant threat to management and conservation priorities as these plants can transform ecosystem functions and processes. In this study, I investigated the non-native, invasive tree, Chinese tallow (Triadica sebifera (L.) Small) in the maritime forests of Parris Island, South Carolina. I studied the role of land-use history and modern forest disturbance in facilitating the invasion of Chinese tallow. I found that stands previously cleared for agriculture and reforested with slash pine (Pinus elliottii Englem.) since the 1970s had significantly more Chinese tallow stems than stands that remained forested since …

Recombinant Dna Modification Of Gibberellin Metabolism Alters Growth Rate And Biomass Allocation In Populus, Haiwei Lu, Venkatesh Viswanath, Cathleen Ma, Elizabeth Etherington, Palitha Dharmawardhana, Olga Shevchenko, Steven H. Strauss, David W. Pearce, Stewart B. Rood, Victor Busov

Michigan Tech Publications, Part 1

Overexpression of genes that modify gibberellin (GA) metabolism and signaling have been previously shown to produce trees with improved biomass production but highly disturbed development. To examine if more subtle types of genetic modification of GA could improve growth rate and modify tree architecture, we transformed a model poplar genotype (Populus tremula × P. alba) with eight genes, including two cisgenes (intact copies of native genes), four intragenes (modified copies of native genes), and two transgenes (from sexually incompatible species), and studied their effects under greenhouse and field conditions. In the greenhouse, four out of the eight tested genes produced …
