Dissolved Inorganic Carbon Metabolism In Bacteria, Jana Wieschollek Oct 2025

Dissolved Inorganic Carbon Metabolism In Bacteria, Jana Wieschollek

USF Tampa Graduate Theses and Dissertations

Dissolved inorganic carbon (DIC: CO2, HCO3⁻, CO32⁻) plays a central role in the metabolism of all living organisms. DIC is necessary for steps in essential biosynthetic processes, such as the synthesis of amino acids and nucleobases; in autotrophic bacteria, organic molecules are synthesized entirely from DIC. To ensure a steady supply of CO2 and HCO3 - needed for biosynthesis and/or autotrophy, organisms use bicarbonate transporters to increase the cytoplasmic concentration of this anion, and carbonic anhydrase (CA) to speed the interconversion of CO2 and HCO3 -, both in the cytoplasm and at the cell surface. This dissertation investigates DIC metabolism …

Oxygen Supply Capacity Of The Atlantic Horseshoe Crab,, Marty Sims Oct 2025

Oxygen Supply Capacity Of The Atlantic Horseshoe Crab,, Marty Sims

USF Tampa Graduate Theses and Dissertations

The horseshoe crab, Limulus polyphemus, inhabits shallow bays and estuaries where it encounters variable oxygen levels. Moreover, each year, the biomedical industry harvests hemolymph from hundreds of thousands of horseshoe crabs to use in bacterial contamination testing, yet the effects of bloodletting on their physiology are relatively unknown. This study aims to determine the oxygen supply capacity of Limulus polyphemus in relation to environmental hypoxia and biomedical bloodletting. Study animals were collected from the intertidal waters of Tampa Bay, Florida. Experiments included a control group that did not undergo substantial blood-volume reduction and a treatment group from which 10% of …

The intestinal mucosal epithelium forms a barrier between luminal contents and the body. MicroRNAs (miRNAs) regulate mucosal homeostasis by controlling inflammatory responses and structural integrity. Here, we discovered a protective role for miR147 in intestinal inflammation using a miR147tdTomato reporter mouse. miR147 was enriched in the intestines, with the highest expression in the colonic epithelial cells at the luminal surface, with prominent expression in differentiated enterocytes. Mice with general or intestinal epithelial deletion of miR147 showed increased intestinal inflammation and diminished mucosal healing during colitis. RNA sequencing of miR147-deficient cells showed dysregulated immune signaling, with upregulated proinflammatory cytokine pathways and …

Grassland For Sustainable Ecosystems, Malcolm Hadley Oct 2025

Grassland For Sustainable Ecosystems, Malcolm Hadley

IGC Proceedings (1977-2023)

Grasslnnds present many advantages for examining issues related to sustainability. Grasslands include planted pastures as well as a variety of natural rangelands in situations ranging from semi-arid to subhumid. Diversity is also reflected in the spectrum of grassland users and uses, for example, nomadic pastoralism, extensive ranches, intensive pastures, wildlife tourism, game hunting. And in terms of sustainability of resource management, grasslands encompass a wide range of contrasting situations and conflicts in resource use. Heavy grazing pressure associated with increasing human populations in certain tropical savannas, the implications of rural depopulation to traditional pasture management in alpine regions, and the …

Science And Information For Our Grasslands, G A. Nores, R R. Vera Oct 2025

Science And Information For Our Grasslands, G A. Nores, R R. Vera

IGC Proceedings (1977-2023)

This paper favours a view of grasslands, and agricultural research in general, that extends well beyond the limits of the scientific community and promotes the active involvement of scientists in current societal debates from a scientific perspective. It is argued that in developed countries environmental concerns rather than production growth will tend to dominate future social debate. In developing countries there is a need to balance agricultural growth with responsible management of natural resources. Needs for new technology go beyond improving biophysical efficiency, and involve economic and social efficiency objectives. The relevance of grassland research is assessed in terms of …

Vegetation Dynamics In Grazed Systems: A Hierarchical Perspective, D D. Briske Oct 2025

Vegetation Dynamics In Grazed Systems: A Hierarchical Perspective, D D. Briske

IGC Proceedings (1977-2023)

Grassland vegetation consists of a series of hierarchical levels including the tiller, plant, population and community which collectively influence the productivity and stability of grazed systems. These hierarchical levels may respond uniformly to influence vegetation dynamics, but frequently additional complexity is encountered by the occurrence of opposing responses between or among hierarchical levels. Consequently, it is important to con­sider responses at several hierarchical levels to achieve an accurate interpretation of vegetation dynamics to graz­ing within the community. The significance of a hierarchical perspective to vegetation management is illustrated with examples from bunchgrass dominated rangelands at the level of the individual …

Forage Conservation And Physico-Chemical Conversion, E Zimmer Oct 2025

Forage Conservation And Physico-Chemical Conversion, E Zimmer

IGC Proceedings (1977-2023)

The factors on which the digestibility of organic matter (dMO) of forages depend are now well-known. In temperate forages, this digestibility depends mainly on the growth stage, the rank of the growth-cycle, and the botanical species. It is constantly decreasing with advancing age, especially during the first growth-cycle. In after­math growth-cycles, high temperatures accelerate the decrease of digestibility with age. Tropical forages follow the same laws, but tropical grasses are less digestible than cool-season grasses, especially at young stages and in warm weather. This is partly due to the fact that high temperatures increase cell-wall contents and lignification, and also …

The Feeding Value Of Forages, C Demarquilly Oct 2025

The Feeding Value Of Forages, C Demarquilly

IGC Proceedings (1977-2023)

The lower productivity of legume based swards and their instability of yield from year to year compared with nitrogen fertilised grass swards continues to be a major constraint on the integration of leguminous nitrogen fixing species into present-day farming systems. Most legume systems have a high biological nitrogen fixation (BNF) potential which is rarely attained in the· field due to limiting environmental or management factors. Enhancement of BNF through manipulation of the Rhizobium and plant components of the symbiosis must be viewed as a long-term objective. Optimisation of nitrogen fixation in the short-term may best be achieved through optimisation of …
