Improving Alternate Lignin Catabolite Utilization Of Ligab From Sphingobium Sp. Strain Syk-6 Through Site Directed Mutagenesis, Kevin P. Barry, Erin F. Cohn, Abraham Ngu, Erika A. Taylor 2015 Wesleyan University

Improving Alternate Lignin Catabolite Utilization Of Ligab From Sphingobium Sp. Strain Syk-6 Through Site Directed Mutagenesis, Kevin P. Barry, Erin F. Cohn, Abraham Ngu, Erika A. Taylor

Erika A. Taylor, Ph.D.

Protocatechuate 4,5-dioxygenase (LigAB) catalyzes dioxygenation of multiple lignin derived aromatic compounds—such as protocatechuate (PCA), gallate (GA) and 3-O-methyl gallate (3OMG)—with decreasing proficiency as the molecule size increases. We predicted that phenylalanine-103 of the α subunit (Phe103α) controls substrate specificity through interaction with the C5-funtionality of bound substrates, and mutagenesis would enhance GA and 3OMG catalysis. LigAB with Phe103α mutations (F103 V, F103T and F103H) displayed enhanced catalytic efficiency for dioxygenation of 3OMG, with mutants displaying 12- to 31-fold increases in View the MathML source, making these mutant enzymes more active with 3OMG than its native dioxygenase (DesZ ...

Professional Agricultural Workers Journal

Abstract

The study assessed the impact of using different stocking rates of goats under pine plantation on plant species occurrence and animal productivity. It was conducted on an 11 year-old loblolly pine plantation site in Epes, Alabama from July to October 2011. Thirty-six Kiko crossbred male goat kids of 4 to 5 months of age were assigned to different stocking rates, namely, low (4 goats/acre), medium (8 goats/acre), and high (12 goats/acre) with three replications each. Forage composition, animal daily gain (ADG) and blood urea nitrogen (BUN) were monitored. Bahia grass (Paspalum notatum) was the most dominant ...


Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar 2015 Fordham University

Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar

Student Theses 2015-Present

This thesis compares and explains the advantages aquaponics farming has over modern industrial intensive farming. Through a comparison natural capital usage, conservation, recycling and cost, the thesis advocates for the expansion of aquaponics usage in urban settings. The thesis also explains the history of intensive farming and aquaponics in America, the science of how aquaponics operates, the economic and environmental costs of modern intensive farming versus aquaponics farming, and the social implications of aquaponics. Lastly, I propose a policy that reallocates farm subsidies by modifying the Farm Bill. Then I propose policies that support creating a new standard of farm ...


Assessment Of Pityophthorus Juglandis Colonization Characteristics And Implications For Further Spread Of Thousand Cankers Disease, Jackson Audley 2015 University of Tennessee - Knoxville

Assessment Of Pityophthorus Juglandis Colonization Characteristics And Implications For Further Spread Of Thousand Cankers Disease, Jackson Audley

Masters Theses

Nonnative, invasive forest insect pests are a significant threat to the health of global forest resources. Thousand cankers disease, a recently described disease threatening walnuts, is the result of an invasive insect-pathogen complex in which the walnut twig beetle (Pityophthorus juglandis Blackman) is a vector to the associated fungal pathogen, Geosmithia morbida. Both are native to the southwestern U.S. into northern Mexico, however, have been found well beyond their historic range, and now threaten black walnut (Juglans nigra) in the eastern U.S. Beetles have likely been spread via the transport of infested walnut logs.

The goal of this ...


White Spruce (Picea Glauca), Moose (Alces Alces) And The Origin Of A Zootic Disclimax Community On Isle Royale, Stephen C. Caird 2015 Northern Michigan University

White Spruce (Picea Glauca), Moose (Alces Alces) And The Origin Of A Zootic Disclimax Community On Isle Royale, Stephen C. Caird

NMU Master's Theses

Understory herbivory combined with canopy loss alters trajectories of forest succession, and in extreme cases may produce novel landscapes dominated by the groundcover layer. I investigated the response of woody species to savannas which have emerged in Isle Royale National Park as a result of moose herbivory. I used dendrochronological methods and microsite plots to describe the spatial, temporal, and competitive responses of white spruce (Picea glauca), a non-palatable species, to the savanna environment. Most tree species had lower densities in savannas, however bird-dispersed species mountain ash (Sorbus decora) and chokecherry (Prunus virginiana) were increasing in older savannas. White spruce ...


Exploration Of Spatial And Temporal Changes In Trophic Status Of Lakes In The Northern Temporal Forest Biome Using Remote Sensing, Aleksey Paltsev 2015 The University of Western Ontario

Exploration Of Spatial And Temporal Changes In Trophic Status Of Lakes In The Northern Temporal Forest Biome Using Remote Sensing, Aleksey Paltsev

University of Western Ontario - Electronic Thesis and Dissertation Repository

There is a critical need for detailed surveys of lakes covering large spatial (>100 km2) and temporal scales (decades) to determine if there is an increase in the magnitude and frequency of phytoplankton blooms. Remote sensing was used to: (1) develop a regression model that relates chlorophyll a (chl-a) as a proxy of lake phytoplankton biomass to Landsat TM and ETM+ optical reflectance (r2=0.85, p

Quantifying Land Cover Change Due To Petroleum Exploration And Production In The Haynesville Shale Region Using Remote Sensing, Daniel Unger, I-Kuai Hung, Kenneth W. Farrish, Darinda Dans

Faculty Publications

The Haynesville Shale lies under areas of Louisiana and Texas and is one of the largest gas plays in the U.S. Encompassing approximately 2.9 million ha, this area has been subject to intensive exploration for oil and gas, while over 90% of it has traditionally been used for forestry and agriculture. In order to detect the landscape change in the past few decades, Landsat Thematic Mapper (TM) imagery for six years (1984, 1989, 1994, 2000, 2006, and 2011) was acquired. Unsupervised classifications were performed to classify each image into four cover types: agriculture, forest, well pad, and other ...

Post-Dispersal Seed Fate Of Ocotea Floribunda (Lauraceae) In Monteverde, Costa Rica, Luis Carlos Beltrán ’15 2015 Lake Forest College

Post-Dispersal Seed Fate Of Ocotea Floribunda (Lauraceae) In Monteverde, Costa Rica, Luis Carlos Beltrán ’15

Senior Theses

Ocotea floribunda (Lauraceae) is a Neotropical, bird-dispersed, canopy tree species commonly found in Monteverde, Costa Rica. The post-dispersal fate of seeds was studied to determine how regurgitation by avian frugivores and microhabitat characteristics affect seed removal through a Giving-Up Density (GUD) experiment. The fate of removed seeds was assessed through a concurrent seed-tagging experiment. An on-site camera trap revealed that agoutis (Dasyprocta punctata) remove regurgitated seeds O. floribunda in the open site. Microhabitat characteristics and seed treatment had no significant effect on seed removal rates. Regurgitated seeds were buried in the seed-tagging experiment. Seed infestation rates were assessed following the ...

Building Resilience Into Quaking Aspen Management, Paul C. Rogers 2015 Utah State University

Building Resilience Into Quaking Aspen Management, Paul C. Rogers

Aspen Bibliography

Throughout the 20th century, forest scientists and land managers were guided by principles of succession with regard to aspen forests. The historical model depicted aspen as a "pioneer species" that colonizes a site following disturbance and is eventually overtopped by conifers. Aspen systems are more diverse, however, than previously described. Not only are there distinctive seral and stable aspen, but variations within these types require appropriate management considerations (Rogers et al. 2014). We recommend a strategic approach to aspen resilience that builds upon traditional aspen ecology and incorporates knowledge of varying aspen functional types, effective monitoring, historical disturbance ecology ...


Managing Ungulate Browsing For Sustainable Aspen, Samuel B. St. Clair, Paul C. Rogers, Michael R. Kuhns 2015 Brigham Young University - Provo

Managing Ungulate Browsing For Sustainable Aspen, Samuel B. St. Clair, Paul C. Rogers, Michael R. Kuhns

Aspen Bibliography

In montane forests of the Intermountain West composition and function are often defined by what happens with quaking aspen. Aspen is a pioneer species that regenerates quickly following disturbance and then establishes ecological conditions under which the rest of the biological community develops. Quaking aspen forests have high biodiversity and provide ideal habitat for many animals. Aspen regeneration from root sprouts is highly palatable to wildlife and livestock. When browsing becomes chronic it leads to regeneration failure and eventual loss of aspen forests and associated species. Ironically, this can result in habitat and forage loss for wildlife and livestock. Here ...


Modeling Predator Habitat To Enhance Reintroduction Planning, Shiloh Michael Halsey, William J. Zielinski, Robert M. Scheller 2015 Portland State University

Modeling Predator Habitat To Enhance Reintroduction Planning, Shiloh Michael Halsey, William J. Zielinski, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

Context

The success of species reintroduction often depends on predation risk and spatial estimates of predator habitat. The fisher (Pekania pennanti) is a species of conservation concern and populations in the western United States have declined substantially in the last century. Reintroduction plans are underway, but the ability of the species to establish a selfsustaining population is affected by predation from its primary predator, the bobcat (Lynx rufus).

Objectives

To develop a habitat model that incorporates both habitat of the focal species and the spatial patterning of predator habitat. To locate areas of densely aggregated habitat that would be suitable ...

Bioenergy Harvest, Climate Change, And Forest Carbon In The Oregon Coast Range, Megan K. Creutzburg, Robert M. Scheller, Melissa S. Lucash, Louisa B. Evers, Stephen D. Leduc, Mark G. Johnson

Environmental Science and Management Faculty Publications and Presentations

Forests provide important ecological, economic and social services, and recent interest has emerged in the potential for using residue from timber harvest as a source of renewable woody bioenergy. The long-term consequences of such intensive harvest are unclear, particularly as forests face novel climatic conditions over the next century. We used a simulation model to project the long-term effects of management and climate change on above- and below ground carbon storage in a watershed in northwestern Oregon. The multi-ownership watershed has a diverse range of current management practices, including little-to-no harvesting on federal lands, short-rotation clear-cutting on industrial land, and ...

Natural Resources and the Environment Scholarship

Abstract Opinions about public lands and the actions of private non-industrial forest owners in the western United States play important roles in forested landscape management as both public and private forests face increasing risks from large wildfires, pests and disease. This work presents the responses from two surveys, a random-sample telephone survey of more than 1500 residents and a mail survey targeting owners of parcels with 10 or more acres of forest. These surveys were conducted in three counties (Wallowa, Union, and Baker) in northeast Oregon, USA. We analyze these survey data using structural equation models in order to assess ...
