The Effect Of Prescribed Fires On Vernal Herbs, 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 ...
Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, 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 ...
Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, 2016 University of Southern Mississippi
Effects Of Fire On Soil Co₂ Efflux In A Mature Longleaf Pine Forest, Knox Lemee Flowers
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 ...
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, 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
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 ...

Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, 2016 California Polytechnic State University - San Luis Obispo
Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson
Master's Theses and Project Reports
It is widely accepted that allelopathy is not only significant, but more or less singular, in the inhibition of understory vegetation in California Eucalyptus globulus (blue gum) plantations. However, there is no published documentation of allelopathy by blue gums against California native species. Here, we present evidence that germination and early seedling growth of five California native species are not inhibited by chemical extracts of blue gum foliage, either at naturally-occurring or artificially concentrated levels. In the greenhouse, seeds were germinated in field-collected soil from mature blue gum plantations and the adjacent native, coastal scrub communities. In petri plates, seeds ...
The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, 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
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, 2016 University of Southern Mississippi
Fire And Fuels: Vegetation Change Over Time In The Zuni Mountains, New Mexico, Luke Wylie
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, 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 ...
Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, 2016 United States Forest Service
Piecemeal Reform Of Trade And Environmental Policy When Consumption Also Pollutes, Mark R. Metcalfe, John C. Beghin
We incorporate endogenous (price-responsive) consumption pollution into a dual trade model to assess welfare effects of coordinated trade and environmental piecemeal reform in a small, open and distorted economy. Pollution is generated by production and consumption. Producers control the level of pollution and face incentives to abate both types of pollution. We identify sufficient conditions for welfare-improving reforms of trade and environmental policies. An additional domestic environmental policy instrument must be imposed on exportables because of their supply response to foreign environmental taxes.
The Impacts Of Elephant Grazing On Plant Succession In Tropical Forests Of Africa, 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 ...

The forest in Massachusetts has changed since the earliest colonial settlement and today the floristic composition is more homogeneous. This study investigates the potential change in the floristic composition over thirty years in Worcester County State Forests. Shannon, richness and evenness indices for two periods were compared, and Jaccard index was used to analyze similarity in composition between the periods. The possible influence of severe weather events was also analyzed.
It was found Changes in the floristic composition, but the magnitude of the changes ...
Benefits And Risks Of Imidacloprid-Based Management Programs For Hemlock Woolly Adelgid, 2016 University of Tennessee - Knoxville
Benefits And Risks Of Imidacloprid-Based Management Programs For Hemlock Woolly Adelgid, Elizabeth Paige Benton
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, 2016 Murray State University
Analysis Of Forest Structure Among Management Types At Land Between The Lakes, Kentucky, Miranda Thompson
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
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, 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, 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.
