The Effect Of Prescribed Fires On Vernal Herbs, Janis Lemaster 2016 Western Kentucky University

The Effect Of Prescribed Fires On Vernal Herbs, Janis Lemaster

Honors College Capstone Experience/Thesis Projects

The effects of fire on vernal herbs are little known. David Kem attempted to assess the influences of spring and winter prescribed fires on vernal herbs by collecting abundance data on three sets of research plots located at the WKU Green River Preserve in Hart County, KY, on April 9-10, 2010. On April 10 he conducted spring burns, and on February 22, 2011, he conducted winter burns. He then collected post-fire data on the abundance of the herbs on the 12-19 of March, 2011. He found little influence of fire on overall species richness and the density of common species ...


Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, Knox Lemee Flowers 2016 University of Southern Mississippi

Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, Knox Lemee Flowers

Master's Theses

This study was conducted from 2012-2013 in a 96 year old longleaf pine at the Lake Thoreau Environmental Center located Lamar County, MS. Measurements of soil CO₂ efflux (i.e., soil respiration or SR) rates (µmol m-2 sec-1) were taken across 8 field plots (4 burned, 4 unburned) before and after a prescribed fire on that occurred in May, 2012. These measurements were taken over diurnal cycles using a LICOR LI-8100A automated soil gas flux system with long term chambers. SR rates and soil temperature measurements were collected during 3 sampling periods in 2012 and 1 sampling period ...


Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch 2016 Stephen F Austin State University

Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch

Electronic Theses and Dissertations

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to ...


Forage Availability And Nutritional Carrying Capacity For Cervids Following Prescribed Fire And Herbicide Applications In Young Mixed-Hardwood Forest Stands In The Cumberland Mountains, Tennessee, Jordan Scott Nanney 2016 University of Tennessee, Knoxville

Forage Availability And Nutritional Carrying Capacity For Cervids Following Prescribed Fire And Herbicide Applications In Young Mixed-Hardwood Forest Stands In The Cumberland Mountains, Tennessee, Jordan Scott Nanney

Masters Theses

I evaluated the influence of timber harvest combined with prescribed fire and/or herbicide in young mixed-hardwood forest on forage availability and nutritional carrying capacity (NCC) for elk (Cervus elaphus) and white-tailed deer (Odocoileus virginianus) at the North Cumberland Wildlife Management Area (WMA), July-August, 2013-15. I combined land cover data, forest management data, field management data, and forage availability data to model summer elk forage availability across the WMA.

I compared forage availability, NCC (animal days/ha) using 12 and 14% crude protein (CP) nutritional constraints, and vegetation composition among 6 young forest treatments, reclaimed surface mines (MINE), and closed-canopy ...

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas 2016 University of San Francisco

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas

Master's Projects

In the past 30 years, anthropogenic activities like urbanization, agriculture, road fragmentation and deforestation have resulted in changes in the land use and land cover (LULC) in the Mexican Water Forest. Due to the important ecosystem services, and the natural resources this forest provides, in Mexico, it has become increasingly necessary to use new technologies and tools to support the planning, implementation and integration of forest management and conservation plans, as well as ecological and socioeconomic analysis of this ecosystem. Remote Sensing techniques and Geographic Information Systems (GIS) have been a true technological and methodological revolution in the acquisition, management ...


Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie 2016 University of Southern Mississippi

Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie

Master's Theses

The Zuni Mountains are a region that has been dramatically changed by human interference. Anthropogenically, fire suppression practices have allowed a buildup of fuels and caused a change in the fire-adapted ponderosa pine ecosystem such that the new ecosystem now incorporates many fire-intolerant species. As a result, the low-severity fires that the ecosystem once depended on to regenerate the forest are much reduced, and these low-severity fires are now replaced by crown-level infernos that threaten the forest and nearby towns. In order to combat these effects, land managers are implementing fuel reduction practices and are striving to better understand the ...


Determining The Pollination Mechanism Of A Problematic Invasive Species In The Gulf South: Triadica Sebifera, Jennifer Wester Clark 2016 University of New Orleans

Determining The Pollination Mechanism Of A Problematic Invasive Species In The Gulf South: Triadica Sebifera, Jennifer Wester Clark

University of New Orleans Theses and Dissertations

Understanding the ecology of invasive species is vital to curb the homogenizing of ecosystems, yet the pollination mechanisms of the Chinese tallow tree (Triadica sebifera) in its introduced habitat remain ambiguous. This study examines self-pollination, wind pollination, and flower-visiting insects of tallow in a bottomland hardwood forest and Longleaf pine savannah in the U.S. Gulf South. These data suggest that self-pollination and airborne pollination are possible, but likely rare occurrences, although the possibility of apoxisis was not investigated. Seed production in exclusion experiments was significantly less than in open-pollinated flowers, and wind dispersal of tallow pollen dropped to essentially ...


The Impacts Of Elephant Grazing On Plant Succession In Tropical Forests Of Africa, Nadia Swit 2016 Cleveland State University

The Impacts Of Elephant Grazing On Plant Succession In Tropical Forests Of Africa, Nadia Swit

The Downtown Review

Succession occurs in an ecosystem when there is a change in the species structure and diversity in an ecological community over time. While this can allow for greater biodiversity, occasionally diversity can be stunted based on the level of disturbance and the invasiveness of the first pioneering species. As in the case of arrested succession, continual disturbance prohibits changes in the environment and suppresses species establishment. The effects of this continued disturbance are seen in the tropical forests in national parks in Uganda and Tanzania in Eastern Africa with African elephants (Loxodonta africana). The continuous browsing on trees by the ...


Benefits And Risks Of Imidacloprid-Based Management Programs For Hemlock Woolly Adelgid, Elizabeth Paige Benton 2016 University of Tennessee - Knoxville

Benefits And Risks Of Imidacloprid-Based Management Programs For Hemlock Woolly Adelgid, Elizabeth Paige Benton

Doctoral Dissertations

Hemlock woolly adelgid, Adelges tsugae (Annand) (HWA) (Hemiptera: Adelgidae), has caused widespread decline of eastern hemlock, Tsuga canadensis (L.) Carriére. This collaborative retrospective analysis with Great Smoky Mountains National Park (GRSM) provides research-based management guidance on imidacloprid treatments and nontarget risks to aquatic systems.

Imidacloprid and olefin concentrations were assessed in foliage from different diameter at breast height (DBH) size hemlocks 4 – 7 yr post-imidacloprid treatment. Imidacloprid concentrations were below the LC50 [lethal concentration] for HWA, but olefin was above the LC50 4 yr post-treatment. HWA populations were suppressed, and hemlock canopies were healthy. Treatment efficacy can last ...

Analysis Of Forest Structure Among Management Types At Land Between The Lakes, Kentucky, Miranda Thompson 2016 Murray State University

Analysis Of Forest Structure Among Management Types At Land Between The Lakes, Kentucky, Miranda Thompson

Scholars Week

Fire is a dynamic disturbance that once created and maintained the oak savannas and oak forests of the Southeast. These forests are characterized by open structures with herbaceous understories, which provide significant habitat and food for native wildlife species. In the absence of fire, canopies close and fire-intolerant, shade-tolerant species begin to crowd the understory and midstory. This process, known as mesophication, occurs when increasingly cool, damp, and shaded conditions create a less flammable fuel bed and improve conditions for mesophytic species creating deteriorating conditions for shade-intolerant, fire-adapted species such as oaks (Quercus spp.). The use of prescribed fire is ...

Assessing The Impacts Of Federal Forest Planning On Wildfire Risk Mitigation In The Pacific Northwest, Usa, Alan A. Ager, Michelle A. Day, Karen C. Short, Cody R. Evers 2016 USDA Forest Service

Assessing The Impacts Of Federal Forest Planning On Wildfire Risk Mitigation In The Pacific Northwest, Usa, Alan A. Ager, Michelle A. Day, Karen C. Short, Cody R. Evers

Environmental Science and Management Faculty Publications and Presentations

We analyzed the impact of amenity and biodiversity protection as mandated in national forest plans on the implementation of hazardous fuel reduction treatments aimed at protecting the wildland urban interface (WUI) and restoring fire resilient forests. We used simulation modeling to delineate areas on national forests that can potentially transmit fires to adjacent WUI. We then intersected these areas with national forest planning maps to determine where mechanical treatments are allowed for restoration and fire protection, versus areas where they are prohibited. We found that a large proportion of the national forest lands (79%) can spawn fires that burn adjacent ...


The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown 2016 Colby College

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric ...

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou 2016 Colby College

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.


Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda 2016 Colby College

Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda

Journal of Environmental and Resource Economics at Colby

This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.


Media Effects On Solar Panel Installations Across 20 States, Casey Romeo 2016 Colby College

Media Effects On Solar Panel Installations Across 20 States, Casey Romeo

Journal of Environmental and Resource Economics at Colby

This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic ...
