Production, Persistence And Diversity Of Species In Temperate Grasslands, Meredith L. Mitchell, Brendan P. Christy Jan 2015

Production, Persistence And Diversity Of Species In Temperate Grasslands, Meredith L. Mitchell, Brendan P. Christy

IGC Proceedings (1993-2023)

Temperate grassland areas are considered to be semi-arid, with rainfall typically between 250 and 500 mm, much of it occurring in the late spring and early summer. Grazing plays an important role in all these grasslands with impacts on diversity and persistence. Against this assumption that seasonal productivity would be more uniform within a pasture that was diverse, the research suggested that species rich pastures were less stable, because this species richness was composed of non-perennial, volunteer and weed species. This paper explores the concept that systems diversity of temperate grassland does not always equate to production. In these systems …

Ecologically And Socially Sustainable Livestock Development In Marginal Areas, Ilse Köhler-Rollefson Jan 2015

Ecologically And Socially Sustainable Livestock Development In Marginal Areas, Ilse Köhler-Rollefson

IGC Proceedings (1993-2023)

“Marginal areas” are perceived as difficult and unproductive landscapes, always under the threat of drought, desertification and poverty. Yet, both dryland and high altitude marginal areas have an extraordinary output of livestock products; in the efficiency of producing human-edible protein they far surpass more fertile areas. This productivity under adverse climatic conditions rests on sophisticated strategies and social institutions developed by pastoral communities to deal with variability in the availability of resources. It depends on the use of animal genetic resources that are adapted to make best use of local vegetation and can cope with seasonal variations in availability. Livestock …

Three Is Company: Fixing The Grazing-Land Business Conundrum, Ralph Von Kaufmann Jan 2015

Three Is Company: Fixing The Grazing-Land Business Conundrum, Ralph Von Kaufmann

IGC Proceedings (1993-2023)

Grazing-lands have the largest footprint on the world’s land surface area but this is not reflected in the amount of business conducted on them. The most common land use systems are very land intensive, i.e., they use a lot of land to produce not very much and few jobs. The health of the planet depends on having healthy grazing-lands but there is a perfect storm brewing in which the demand from expanding pastoral communities for more food and jobs cannot be met just by applying good grazing-land management practices. Compatible businesses must be found that can create jobs without increasing …

Thiol Dioxygenases: An Investigation Into The Mechanisms Of Cysteine Dioxygenase And 3-Mercaptopropionic Acid Dioxygenase, Joshua Crowell

Chemistry & Biochemistry Dissertations

Thiol dioxygenase (TDO) enzymes catalyze the molecular oxygen-dependent oxidation of sulfur containing amino acid derivatives. The loss of the ability to regulate thiols has been linked to a number of neurological diseases. Two TDO enzymes, a mammalian cysteine dioxygenase (CDO) and a bacterial 3-mercaptopropionic acid dioxygenase, are examined by probing the various effects on the steady-state kinetic parameters kcat and kcat/KM. Both of these enzymes show a similar deviation from the iconic 2-His-1-carboxylate facial triad active site motif that dominates the mononuclear non-heme iron oxidase/oxygenase class of enzymes. However, CDO shows an unusual covalently crosslinked Cys-Tyr pair within 3.3 Å …

Quality Seed Production And Effective Marketing Systems For Development Of Grasslands, M. Philip Rolston Jan 2015

Quality Seed Production And Effective Marketing Systems For Development Of Grasslands, M. Philip Rolston

IGC Proceedings (1993-2023)

Seed quality is defined as (i) maintaining genetic purity using seed certification principles (generation system; isolation; previous cropping history); (ii) achieving high levels of physical purity (especially low weed seed levels) by in field weed control and seed cleaning; (iii) achieving high levels of seed germination at harvest and maintaining germination through the seed supply chain. Seed production systems must not only produce high quality seed but also achieve economic seed yields. Seed crops have to be profitable (by being high yielding) to justify the investment of time and input costs to achieve quality. This in turn requires supporting research …

Biochemical, Kinetic And Spectroscopic Characterizations Of Non-Heme Iron Oxygenase Enzymes, Bishnu P. Subedi

Chemistry & Biochemistry Dissertations

MiaE is a non-heme diiron enzyme which catalyzes the O2-dependent hydroxylation of selected tRNA-nucleotides as part of a multienzyme posttranscriptional hypermodification pathway. This tRNA-modifying enzyme is postulated to signal O2-availability within the pathogenic bacteria, Salmonella typhimurium. Recombinant MiaE was cloned from Salmonella typhimurium genomic DNA, purified to homogeneity, and characterized by steady-state kinetics and spectroscopic techniques (UV-visible, Circular Dichroism, dual mode electron paramagnetic resonance (EPR), and Mössbauer) for comparison to other non-heme diiron enzymes. Remarkably, regardless of the substrate used in peroxide-shunt assays, hydroxylation of the terminal isopentenyl-C4-position was observed with > 97% E-stereoselectivity. The role of tRNA-protein macromolecular interactions on …

Valuing Variability--New Perspectives On Climate Resilient Dryland Development, Saverio Kratli Jan 2015

Valuing Variability--New Perspectives On Climate Resilient Dryland Development, Saverio Kratli

IGC Proceedings (1993-2023)

Valuing Variability is a challenge to the view of the drylands as naturally vulnerable to food insecurity and poverty. It argues that improving agricultural productivity in dryland environments is possible by working with climatic uncertainty rather than seeking to control it – a view that runs contrary to decades of development practice in arid and semi-arid lands.

Analyzing Site Suitability For Baldcypress (Taxodium Distichum) Regeneration Along A Hydrologic Gradient In South Louisiana Swamps, Marcus Rutherford

LSU Master's Theses

The future of Louisiana’s coastal cypress-tupelo forests is threatened by prolonged or permanent flooding during the growing season. Permanent inundation prevents baldcypress seedlings from becoming established. The upper limit of submergence with respect to adequate planted baldcypress seedling performance has not been effectively tested under actual field conditions. Similarly, an effective method for determining a site’s regeneration potential based on present vegetation attributes has not been developed. To test first-year performance of planted baldcypress seedlings under varying levels of submergence, I planted 900 of both 1-0 and 2-0 age-class bare-root seedlings across 12 different sites covering a range of hydrologic …

A Plausibly Deniable Encryption Scheme For Personal Data Storage, Andrew Brockmann Jan 2015

A Plausibly Deniable Encryption Scheme For Personal Data Storage, Andrew Brockmann

HMC Senior Theses

Even if an encryption algorithm is mathematically strong, humans inevitably make for a weak link in most security protocols. A sufficiently threatening adversary will typically be able to force people to reveal their encrypted data. Methods of deniable encryption seek to mend this vulnerability by allowing for decryption to alternate data which is plausible but not sensitive. Existing schemes which allow for deniable encryption are best suited for use by parties who wish to communicate with one another. They are not, however, ideal for personal data storage. This paper develops a plausibly-deniable encryption system for use with personal data storage, …
