Implications Of Salinity Normalization Of Seawater Total Alkalinity In Coral Reef Metabolism Studies, Travis A. Courtney, Tyler Cyronak, Alyssa J. Griffin, Andreas J. Andersson

Marine & Environmental Sciences Faculty Articles

Salinity normalization of total alkalinity (TA) and dissolved inorganic carbon (DIC) data is commonly used to account for conservative mixing processes when inferring net metabolic modification of seawater by coral reefs. Salinity (S), TA, and DIC can be accurately and precisely measured, but salinity normalization of TA (nTA) and DIC (nDIC) can generate considerable and unrecognized uncertainties in coral reef metabolic rate estimates. While salinity normalization errors apply to nTA, nDIC, and other ions of interest in coral reefs, here, we focus on nTA due to its application as a proxy for net coral reef calcification and the importance for …

The Utilization Of Enzymes And Enzyme Products For Antimicrobial Effects, Brandon Edward Burdette

Theses and Dissertations

Bacterial resistance is outpacing the discovery of novel antimicrobials. Therefore, it is essential to look at antimicrobials using novel methods. MTAN is a crucial enzyme for some bacteria such as Helicobacter pylori. Transition state analog inhibitor design and fragment-based drug design are drug design approaches typically used independently, but combining these techniques yields inhibitors that bind tightly and are effective in pM concentrations. We demonstrate the efficacy of the combined techniques by investigating the inhibition of HpMTAN, which is an essential enzyme. Enzyme byproducts can also be effective for causing bacterial cell death, hydrolyzing GsdmD by caspases-1/4/5/11 results in an …

Valuing The Pasture Resource - Importance Of Perennials In Higher Rainfall Regions Of South Eastern Australia, P. M. Dowling, R. E. Jones, David R. Kemp, D. L. Michalk

IGC Proceedings (1977-2023)

The premature decline of perennial grass based pastures in southern temperate Australia results in poor productivity and unstable pastures that allow invasion by less desirable weedy species and the potential for soil degradation. The loss of perennial species is attributed to overgrazing arising from an undervaluation of the pasture resource. Resowing pastures is largely uneconomic so maintenance of, or increasing the perennial, is dependent on improved grazing and pasture management practices. A key to changing perceptions is valuing the true worth of the perennial component. Results are presented from a model that takes into account the seasonality of production of …
