Dynamics Of Resprouting And Forest Regeneration Following Anthropogenic Land Use In The Central Amazon Basin, Scott Lawrence Kosiba
Dynamics Of Resprouting And Forest Regeneration Following Anthropogenic Land Use In The Central Amazon Basin, Scott Lawrence Kosiba
LSU Doctoral Dissertations
Tree mortality is increasing with the effects of climate change and drought across the Amazon Basin while intense fires are becoming more prevalent. Tropical moist forest trees generally lack adaptations that protect against mortality during an intense fire, so anthropogenic burning typically kills high percentages of trees. Following disturbances where prescribed burning is used to limit woody encroachment and to fertilize the soil, abandoned land in central Amazonia becomes dominated by the pioneer tree genus, Vismia. Although the mechanisms by which Vismia comes to dominate previously-burned areas are not known, previous studies on anthropogenic land use and forest succession …

Structure And Functional Potential Of Microbial Communities In Subglacial Lake Whillans And At The Ross Ice Shelf Grounding Zone, West Antarctica, Amanda Marie Achberger
LSU Doctoral Dissertations
The abundance of liquid water found beneath the Antarctic Ice Sheet (AIS) is thought to provide a suitable habitat for microbial life. However, the thick ice sheet has posed a significant obstacle to accessing this isolated system and as a consequence, little data exists to infer ecosystem processes occurring beneath ice sheets. To address this deficit, data generated through 16S rRNA (genes and molecules) and metagenomic sequencing was used to evaluate the diversity and potential metabolic function of communities inhabiting Subglacial Lake Whillans (SLW) and the ocean basin into which it discharges (Whillans Ice Stream grounding zone; WIS-GZ). The analysis …
Metabolic Preconditioning Of Mammalian Cells: Approaches For Increasing Biostability After Desiccation, Apurva Shrihari Borcar
Metabolic Preconditioning Of Mammalian Cells: Approaches For Increasing Biostability After Desiccation, Apurva Shrihari Borcar
LSU Doctoral Dissertations
Selected species in nature are able to tolerate prolonged periods of severe water stress. Survival of cellular desiccation in these anhydrobiotic organisms is conferred by a number of mechanisms including accumulation of stabilizing solutes, such as trehalose, and expression of Late Embryogenesis Abundant (LEA) proteins. An additional feature shared by some anhydrobiotic animals is the capacity to suppress mitochondrial oxidative phosphorylation in preparation for desiccation. These mechanisms improve the physiological robustness of cells to stress. The primary aim of this dissertation is to evaluate forms of metabolic preconditioning and to test the most propitious as a means to improve desiccation …
