Effects Of Understory Vegetation And Litter On Plant Nitrogen (N), Phosphorus (P), N∶P Ratio And Their Relationships With Growth Rate Of Indigenous Seedlings In Subtropical Plantations, Jun Wang, Dafeng Hui, Hai Ren, Zhanfeng Liu, Long Yang
Biology Faculty Research
Establishing seedlings in subtropical plantations is very important for forest health, succession and management. Information on seedling nutrient concentrations is essential for both the selection of suitable indigenous tree species to accelerate succession of the established plantation and sustainable forest management. In this study, we investigated the concentrations of nitrogen ([N]), phosphorus ([P]), and N∶P ratio in leaves, stems and roots of seedlings of three indigenous tree species (Castanopsis chinensis, Michelia chapensis and Psychotria rubra) transplanted with removing or retaining understory vegetation and litter at two typical subtropical forest plantations (Eucalyptus plantation and native species plantation). We also measured the …

Genetic Engineering Of Black Cherry (Prunus Serotina) For Reproductive Sterility And Insect Pest Resistance, Ying Wang
Open Access Dissertations
Black cherry (Prunus serotina Ehrh.) is one of the most valuable hardwoods for high- end cabinetry, furniture, architectural millwork, paneling, and veneer. However, the damage caused by cambial-mining insect pests triggers gummosis in black cherry, a non-specific defense response in which resinous gum is deposited at the site of injury. The gum defects dramatically decrease the yield of high-quality black cherry lumber, and the value can be reduced by as much as 90%. The goal of this project was to optimize the transformation and in vitro rooting system, and to develop transgenic black cherry for reproductive sterility and insect pest …

Recent climatic trends and climate model projections indicate that climate change will modify rangeland ecosystem functions and the services and livelihoods that they provision. Recent history has demonstrated that climatic variability has a strong influence on both ecological and social components of rangeland systems and that these systems possess substantial capacity to adapt to climatic variability. Specific objectives of this synthesis are to: 1) evaluate options to mitigate greenhouse gas emissions and future climate change; 2) survey actions that individuals, enterprises, and social organizations can use to adapt to climate change; and 3) assess options for system transformation when adaptation …

Why I Love Grasshopper Sparrows, Michele Patenaude
UVM Libraries Conference Day
Since 2001, Michele (a library circulation supervisor in her day job) has conducted a summer breeding-bird survey of Grasshopper Sparrows at Camp Johnson in Colchester, VT. Named Grasshopper Sparrows because their breeding call sounds like a grasshopper, this little brown bird is endemic to certain types of scrubby grasslands which are becoming more scarce in the Northeast. The Grasshopper Sparrow is also declining and the species is not on the list of Vermont Endangered Birds. Come to this presentation and learn about the bird, how Michele surveys them, why they are endangered, and why Michele loves these quiet, little brown …
Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr
Elk (Cervus Elaphus) Seasonal Habitat Selection In A Heterogeneous Forest Structure, Jesse N. Popp, David N.C. Mcgeachy, Josef Hamr
Aspen Bibliography
Seasonal habitat selection by the reintroduced Burwash elk population, approximately 30 km south of Sudbury, Ontario, has been analysed in order to assist in the development of future management. Twenty-five adult females were radio-collared and tracked 1–3 times a week for 3 years. The most prominent patterns included selection of intolerant hardwood forests (trembling aspen, white birch, and balsam poplar) during all seasons, while Great Lakes-St. Lawrence pines (white and red pine dominated stands) were used less than expected based on availability for all seasons. The selection patterns are likely associated with seasonal climatic conditions and forage preferences. Because the …
Multiple Approaches For Assessing Mangrove Biophysical And Biochemical Variables Using In Situ And Remote Sensing Techniques, Francisco Javier Flores De Santiago
Multiple Approaches For Assessing Mangrove Biophysical And Biochemical Variables Using In Situ And Remote Sensing Techniques, Francisco Javier Flores De Santiago
Electronic Thesis and Dissertation Repository
Mangrove forests are important ecosystems and play a key role in maintaining the equilibrium in coastal lagoons and estuaries. However, in recent years, there has been a considerable loss of mangrove extension due to anthropogenic activities. Recent studies suggest that multiple in situ and remote sensing approaches must be carried out to understand the dynamics in these complex ecosystems. Therefore, the objective for this PhD dissertation is to develop multiple techniques for monitoring the seasonal biophysical and biochemical conditions of the mangrove forests. Particular objectives will include: i. Test the feasibility of using a Chlorophyll Content Index from a …

Long-Term Nitrogen Addition Decreases Carbon Leaching In A Nitrogen-Rich Forest Ecosystem, X. Lu, Frank S. Gilliam, G. Yu, H. Chen, J. Mo
Biological Sciences Faculty Research
Dissolved organic carbon (DOC) plays a critical role in the carbon (C) cycle of forest soils, and has been recently connected with global increases in nitrogen (N) deposition. Most studies on effects of elevated N deposition on DOC have been carried out in N-limited temperate regions, with far fewer data available from N-rich ecosystems, especially in the context of chronically elevated N deposition. Furthermore, mechanisms for excess N-induced changes of DOC dynamics have been suggested to be different between the two kinds of ecosystems, because of the different ecosystem N status. The purpose of this study was to experimentally examine …

Emergent Fungal Entomopathogen Does Not Alter Density Dependence In A Viral Competitor, Andrew M. Liebhold, Ruth Plymale, Joseph S. Elkinton, Ann E. Hajek
Emergent Fungal Entomopathogen Does Not Alter Density Dependence In A Viral Competitor, Andrew M. Liebhold, Ruth Plymale, Joseph S. Elkinton, Ann E. Hajek
Articles
Population cycles in forest Lepidoptera often result from recurring density-dependent epizootics of entomopathogens. While these systems are typically dominated by a single pathogen species, insects are often infected by multiple pathogens, yet little is known how pathogens interact to affect host dynamics. The apparent invasion of northeastern North America by the fungal entomopathogen Entomophaga maimaiga some time prior to 1989 provides a unique opportunity to evaluate such interactions. Prior to the arrival of E. maimaga, the oscillatory dynamics of host gypsy moth, Lymantria dispar, populations were apparently driven by epizootics of a nucleopolyhedrovirus. Subsequent to its emergence, E. …

Development And Application Of Mass Spectrometry-Based Proteomics To Generate And Navigate The Proteomes Of The Genus Populus, Paul Edward Abraham
Doctoral Dissertations
Historically, there has been tremendous synergy between biology and analytical technology, such that one drives the development of the other. Over the past two decades, their interrelatedness has catalyzed entirely new experimental approaches and unlocked new types of biological questions, as exemplified by the advancements of the field of mass spectrometry (MS)-based proteomics. MS-based proteomics, which provides a more complete measurement of all the proteins in a cell, has revolutionized a variety of scientific fields, ranging from characterizing proteins expressed by a microorganism to tracking cancer-related biomarkers. Though MS technology has advanced significantly, the analysis of complicated proteomes, such as …

Distribution And Growth Of Autumn Olive In A Managed Landscape, Matthew Ruddick Moore
Masters Theses
Invasions by exotic plant species result in significant challenges for forest managers. Disturbance and increased light have been shown to facilitate the successful establishment and invasion of exotic, invasive plant species. Several studies have sought to determine which key factors lead to greater abundance of exotic, invasive plants on certain sites and this information is important for determining the likelihood for exotic plant invasions at broad scales. Site characteristics that may promote autumn olive (Elaeagnus umbellata) were studied. Our goal was to identify variables associated with forest road edges most important in explaining autumn olive abundance and growth. …

The Life History And Control Of Pityophthorus Juglandis Blackman On Juglans Nigra L. In Eastern Tennessee, Katheryne Avery Nix
Masters Theses
In the last decade, western states have experienced an increasing mortality rate in Juglans nigra L., black walnut, as a result of the fungal species Geosmithia morbida Kolařík et al. that results in numerous cankers that girdle the branches, resulting in dieback and tree mortality. The only known vector of G. morbida is the walnut twig beetle (WTB), Pityophthorus juglandis Blackman. This newly recognized disease/insect complex has been named Thousand Cankers Disease (TCD) due to the quantity of cankers produced by G. morbida.
Recently, TCD was discovered in the eastern U.S. To limit the spread of TCD in eastern …

Estimated Losses Of Plant Biodiversity Across The U.S. From Historical N Deposition From 1985—2010., Christopher M. Clark, Philip E. Morefield, Frank S. Gilliam, Linda H. Pardo
Biological Sciences Faculty Research
Although nitrogen (N) deposition is a significant threat to herbaceous plant biodiversity worldwide, it is not a new stressor for many developed regions. Only recently has it become possible to estimate historical impacts nationally for the United States. We used 26 years (1985–2010) of deposition data, with ecosystem-specific functional responses from local field experiments and a national critical loads (CL) database, to generate scenario-based estimates of herbaceous species loss. Here we show that, in scenarios using the low end of the CL range, N deposition exceeded critical loads over 0.38, 6.5, 13.1, 88.6, and 222.1 million ha for the Mediterranean …
Sump Diving “River Caves”, Mark Wenner
Sump Diving “River Caves”, Mark Wenner
Mammoth Cave Research Symposia
Note: “Sump” is a term used in caving to describe a passage in a cave that is submerged under water.
Sump diving, and “lure of the sump” originated in the UK in the early 1920’s, as did the use of “rebreather’s, and the “self-contained underwater breathing apparatus”, S.C.U.B.A. The techniques developed by cavers, and “sump divers” in Europe, and then used in British cave systems like Wookey Hole set a cave diving precedence; the development of a unique style, and system for diving caves. These diving practices and techniques influenced the exploration of resurgences, springs, siphons, and river caves throughout …
Sable Melodists, Janet Bass Smith
Sable Melodists, Janet Bass Smith
Mammoth Cave Research Symposia
Inside Mammoth Cave on Broadway Avenue, between the last TB hut and Star Chamber, the name Sable Melodists is inscribed on the wall, using what appears to be charcoal. Next to Sable Melodists are the names of two men: R. H. Condon, and J. M. Foans. (See Figures 1, 2, and 3) When the name Sable Melodists was researched several years ago, the only information available was that it was a minstrel group. A recent search revealed more information, and provoked a more complete investigation of minstrel groups and minstrel shows, and their evolution.

Mammoth Cave National Park Npscape, Lillian Scoggins, Shepard Mcaninich
Mammoth Cave Research Symposia
NPScape is designed to address questions related to resource conservation Vulnerability and Opportunity. These dynamics are shaped at the landscape scale by three major factors: Natural Systems, Human Drivers, and Conservation Context. Consider by way of example a focal resource occurring inside a park. That resource is capable of persisting in part because of the ecological attributes of the larger natural system within which it exists. However, the value of the natural system with respect to the focal resource can be challenged by human-mediated drivers of landscape change. Precisely how these drivers interact with the natural system to impact the …

Improvements To The Rv Waste-Transfer Station Design To Reduce Contaminated Storm Runoff, David Solomon, Sean Mcmillian, Ashley West, Lonnie Sharpe
Mammoth Cave Research Symposia
Mammoth Cave in Central Kentucky is the world’s longest cave system and has been designated an international biosphere. It has unique organisms that live in the cave system and they are dependant upon high quality water supplied through rain recharge. We have documented quaternary ammonia compounds (QAC) levels ranging from 0.2 to 22 mg/L in storm fl ow, as well as, other chemicals coming from the RV waste-transfer station. The objective of this project was to re-design the drain system around the dump station to prevent spillage from washing down into the cave. The first design feature is a v-trench …

Use Of Sorption Isotherms To Improve The Efficacy Of The Storm-Water Filters, Hung-Wai Ho, Rick Toomey
Mammoth Cave Research Symposia
Sorption has been widely used as an inexpensive and environmental friendly water treatment technology. A large variety of adsorbents with different adsorption mechanisms have drawn interests, and combinations of adsorbents will enhance sorption of mixed solutions. However, current sorption research tends to focus on single material. The objective of this study was to develop sorption isotherms for ZPG®, (Zeolite, Perlite, Granular Activated Carbon), used in a stormwater filter cartridge. Contaminants of concern include Cu2+ and quaternary ammonia compounds (QAC). Adsorption isotherms were established for Cu2+ and QAC, and the best fit for the isotherm data was a Langmuir isotherm for …

Three Examples Of Chemical Transport In Storm Runoff At Mammoth Cave National Park, Kentucky, Ashley West, David Solomon, Hung-Wai Ho, Victor Roland, Irucka Embry, Rick Toomey, Roger Painter, Lonnie Sharpe, Dafeng Hui
Mammoth Cave Research Symposia
The karst landscape at Mammoth Cave National Park, Kentucky, was formed by water through the dissolution of soluble rocks forming sinkholes, disappearing streams, emerging springs, closed depressions, and a combination of wet and dry caves. The Park’s cave streams and pools provide a home to unique organisms. Surface waters in the Park tend to rapidly drain into subsurface geologic features and caves. This rapid infiltration makes the subsurface vulnerable to contamination. The objective of this investigation was to characterize chemical transport from the surface into the cave. The preliminary results were achieved by tracer studies and monitoring water chemistry along …

Multiple Storm Event Impacts On Epikarst Storage And Transport Of Organic Soil Amendments In South-Central Kentucky, Jason Polk, Sean Vanderhoff, Chris Groves, Benjamin Miller, Carl Bolster
Mammoth Cave Research Symposia
The groundwater in agricultural karst areas, such as Kentucky’s Pennyroyal Plateau, is susceptible to contamination from organic soil amendments and pesticides. During 2011, water samples and geochemical data were collected every four hours before, during, and between storm events from a waterfall in Crumps Cave from January to September to track the transport and residence time of epikarst water and organic soil amendments during variable fl ow conditions. Geochemical data consisting of pH, specific conductivity, temperature, and discharge were collected continuously at 10-minute intervals, along with rainfall amounts. The changes in geochemistry indicate simultaneous storage and transport of meteoric water …
