Plant Responses To Drought In A Semiarid Grassland: An Isotopic Approach, Elizabeth V. Fain

Biology ETDs

Dryland ecosystems are facing unprecedented climate extremes as a result of global climate change. Water is the most limiting factor in dryland ecosystems, therefore plants in drylands have developed crucial water-use strategies for drought survival. It is important to understand plant physiological responses to water stress as drylands are projected to experience more frequent, severe droughts in the coming decades. To test how plants respond to drought in a semiarid grassland, we measured δ13C, δ15N, and C/N ratio of common C3 and C4 plants (Bouteloua gracilis, B. eriopoda, Pleuraphis jamesii, Salsola tragus, Machaeranthera pinnatifida, …

Evaluating The Effect Of Woodchips On Soil Matric Potential, Temperature, Weed Biomass, And Yield Of Selected Crops, Leonard Githinji, Patrick Johnson

Professional Agricultural Workers Journal

Organic mulches are very popular for weed control in sustainable agricultural systems where the application of synthetic herbicides is restricted. A study was conducted to evaluate the effectiveness of organic mulch in controlling weeds, enhancing soil matric potential, and soil temperature. Blended hardwood mulch was applied to the soil surface at a thickness of 10 cm. The experimental design was laid out as a completely randomized design with two treatments, viz., mulch and no-mulch, replicated 5 times. Data were collected during the growing period for weed biomass, soil matric potential, soil temperature, and yield of selected crops. Results from a …

Gendered Geographies Of Care: Women As Health Workers In An Indigenous Health Project In The Peruvian Amazon, Daniela Peluso

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article examines how women as primary gatekeepers for well being became involved as health promoters in a local indigenous health care project in the Amazonian region of Madre de Dios, Peru. Here, I provide a case study of the processes and transitions that the project underwent from its inception to its eventual inclusion of indigenous women health promoters into its programs among indigenous communities from the mid 1980’s through the early 1990’s, at a time when western primary health care was even less accessible then it is today. The article begins with an overview of Madre de Dios and …

The Immune Synapses Reveal Aberrant Functions Of Cd8 T Cells During Chronic Hiv Infection, Nadia Anikeeva, Maria Steblyanko, Leticia Kuri-Cervantes, Marcus Buggert, Michael R. Betts, Yuri Sykulev

Department of Microbiology and Immunology Faculty Papers

Chronic HIV infection causes persistent low-grade inflammation that induces premature aging of the immune system including senescence of memory and effector CD8 T cells. To uncover the reasons of gradually diminished potency of CD8 T cells from people living with HIV, here we expose the T cells to planar lipid bilayers containing ligands for T-cell receptor and a T-cell integrins and analyze the cellular morphology, dynamics of synaptic interface formation and patterns of the cellular degranulation. We find a large fraction of phenotypically naive T cells from chronically infected people are capable to form mature synapse with focused degranulation, a …

The Risks Posed By Mosquito Ultra-Low Volume Applications To Procambarus Clarkii Production, Timothy Mcnamara

LSU Doctoral Dissertations

Mosquito abatement has received much scrutiny due to concerns about the impacts of control applications on non-target organisms. In Louisiana, a great deal of this concern has come from crawfish farmers claiming mosquito abatement applications have damaged crawfish production. To determine which mosquito abatement practices and products pose a risk to crawfish production, we conducted a series of studies examining mosquito abatement practices in the vicinity of crawfish production fields and the impacts of common mosquito abatement product exposure on crawfish health and production. We found that mosquito ULV applications are the most likely to result in exposure to crawfish …

Community Health Workers In Central-Southern Amazonia: An Ethnographic Account Of The Munduruku People Of Kwatá Laranjal Indigenous Land, Daniel Scopel, Raquel Dias-Scopel, Esther Jean Langdon

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article analyzes the role of Munduruku indigenous community health workers (CHW) with the expansion of biomedical services as part of state presence and territorial control in Brazil. Centuries of interethnic contacts among the Munduruku have resulted in a plurality of health practices. Since 1999, Primary services have increased significantly, when the Indigenous Health System (SASI) was created. CHWs were incorporated as part of the health teams serving the indigenous lands. Munduruku CHWs have not only assumed an important role in the delivery of biomedical services, but also are key in the articulation between different traditions of care. Although there …

The Detection Of Periodic Reemergence Events Of Sars-Cov-2 Delta Strain In Communities Dominated By Omicron., Claire E. Westcott, Kevin J. Sokoloski, Eric C. Rouchka, Julia H. Chariker, Rochelle H. Holm, Ray A. Yeager, Joseph B. Moore Iv, Erin M. Elliott, Daymond Talley, Aruni Bhatnagar

Faculty and Staff Scholarship

Despite entering an endemic phase, SARS-CoV-2 remains a significant burden to public health across the global community. Wastewater sampling has consistently proven utility to understanding SARS-CoV-2 prevalence trends and genetic variation as it represents a less biased assessment of the corresponding communities. Here, we report that ongoing monitoring of SARS-CoV-2 genetic variation in samples obtained from the wastewatersheds of the city of Louisville in Jefferson county Kentucky has revealed the periodic reemergence of the Delta strain in the presence of the presumed dominant Omicron strain. Unlike previous SARS-CoV-2 waves/emergence events, the Delta reemergence events were geographically restricted in the community …

Utilizing Maternal Investment Strategies Of Sharks To Develop Management Tools To Aid In Shark Conservation, Dennis Deeken

USF Tampa Graduate Theses and Dissertations

Every generation, breeding females and males repopulate ecosystems with the next generation of offspring. Two models link maternal investments in offspring size and number to natural selection processes. In unstable resource environments, bet-hedging models predict a conservative tradeoff in maternal investments resulting in moderate egg size and clutch size within a given range of sizes for a given species. r/K selection models make predictions on maternal investments across species. In unstable resource environments, r-selected species invest in large broods of small offspring. In stable environments, K-selected species invest in small broods of large offspring. The maternal risk management model predicts …

To Be Or Not To Be: A Tale Of Staphylococcal Gpsb, Lauren R. Hammond

USF Tampa Graduate Theses and Dissertations

There are two big drivers motivating studies into bacterial cell division. The first is a desire to understand life around us. One of the defining characteristics of life is the ability for a cell to grow and divide, and without in-depth knowledge of this process, we cannot truly understand the complexities that allow for life on this planet. The second motivator is to identify new drug targets in the ongoing fight against antimicrobial resistance. Many infectious organisms have become resistant to commonly used antibiotics, and the bacterial cell division machinery is a largely untapped essential process with many potential therapeutic …

Lord Of The Z-Rings: Uncovering The Role Of Mraz And Ftsl In Bacillus Subtilis Cell Division, Maria Louise White

USF Tampa Graduate Theses and Dissertations

Cell division is a complex and highly orchestrated process that requires careful coordination. The process of cell division in prokaryotes primarily occurs via binary fission, where one mother cell becomes two genetically identically and equally sized daughter cells. In most bacteria a key protein, FtsZ, forms a FtsZ ring (Z-ring) to mark the division site and recruit proteins involved in cytokinesis. Whilst much has been learned about the contents and assembly of the divisome in model organisms such as Escherichia coli and Bacillus subtilis factors governing the regulation of divisome are much more poorly understood. …

Design And Assessment Of A Novel Edna Survey Method For The Eastern Indigo Snake (Drymarchon Couperi), Emily K. Galbraith

USF Tampa Graduate Theses and Dissertations

1. Accurate information about species range declines is the cornerstone of effective conservation when habitat loss drives biodiversity loss. The Eastern Indigo snake (Drymarchon couperi) is an apex predator in Florida and, like many other native Florida species, is threatened by widespread habitat destruction. Environmental DNA (eDNA) monitoring of this elusive snake would provide a low-risk and low-cost approach to expand our knowledge of the species’ range and distribution.

2. We designed and tested an eDNA assay that can detect the presence of Eastern Indigo snake from soil samples of their natural habitat. This assay was …

Range-Bounded Adaptive Therapy In Metastatic Prostate Cancer, Renee Brady-Nicholls, Heiko Enderling

Faculty, Staff and Student Publications

Adaptive therapy with abiraterone acetate (AA), whereby treatment is cycled on and off, has been presented as an alternative to continuous therapy for metastatic castration resistant prostate cancer (mCRPC). It is hypothesized that cycling through treatment allows sensitive cells to competitively suppress resistant cells, thereby increasing the amount of time that treatment is effective. It has been proposed that there exists a subset of patients for whom this competition can be enhanced through slight modifications. Here, we investigate how adaptive AA can be modified to extend time to progression using a simple mathematical model of stem cell, non-stem cell, and …

Characterization Of A Bioactive Peptide T14 In The Human And Rodent Substantia Nigra: Implications For Neurodegenerative Disease, Susan Adele Greenfield, Giovanni Ferrati, Clive W Coen, Auguste Vadisiute, Zoltan Molnár, Sara Garcia-Rates, Sally Frautschy, Gregory M Cole

Faculty, Staff and Student Publications

The substantia nigra is generally considered to show significant cell loss not only in Parkinson's but also in Alzheimer's disease, conditions that share several neuropathological traits. An interesting feature of this nucleus is that the pars compacta dopaminergic neurons contain acetylcholinesterase (AChE). Independent of its enzymatic role, this protein is released from pars reticulata dendrites, with effects that have been observed in vitro, ex vivo and in vivo. The part of the molecule responsible for these actions has been identified as a 14-mer peptide, T14, cleaved from the AChE C-terminus and acting at an allosteric site on alpha-7 nicotinic receptors, …

Solid wastes deposited in the coastal zone that date from an era of lax environmental regulations continue to pose significant challenges for regulators and coastal managers worldwide. The increasing risk of contaminant release from these legacy disposal sites, due to a range of factors including rising sea levels, associated saline intrusion, and greater hydrological extremes, have been highlighted by many researchers. Given this widespread challenge, and the often-limited remedial funds available, there is a pressing need for the development of new advanced site prioritization protocols to limit potential pollution risks to sensitive ecological or human receptors. This paper presents a …

The COVID-19 pandemic along with its confinement period boosted lifestyle modifications and impacted women and men differently which exacerbated existing gender inequalities. The main objective of this paper is to assess the gender-based differentials in food consumption patterns, dietary diversity and the determinants favoring weight change before and amid the COVID-19 pandemic among Arab men and women from 10 Arab countries. A cross-sectional study was conducted based on a convenience sample of 12,447 households' family members (mean age: 33.2 ± 12.9; 50.1% females) and information from participants aged 18 years and above was collected about periods before and during the …

Bap1 Maintains Hif-Dependent Interferon Beta Induction To Suppress Tumor Growth In Clear Cell Renal Cell Carcinoma., Lauren Langbein, Rayan El Hajjar, Shen He, Eleonora Sementino, Zhijiu Zhong, Wei Jiang, Benjamin E Leiby, Li Li, Robert G Uzzo, Joseph R Testa, Haifeng Yang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BRCA1-associated protein 1 (BAP1) is a deubiquitinase that is mutated in 10-15% of clear cell renal cell carcinomas (ccRCC). Despite the association between BAP1 loss and poor clinical outcome, the critical tumor suppressor function(s) of BAP1 in ccRCC remains unclear. Previously, we found that hypoxia-inducible factor 2α (HIF2α) and BAP1 activate interferon-stimulated gene factor 3 (ISGF3), a transcription factor activated by type I interferons and a tumor suppressor in ccRCC xenograft models. Here, we aimed to determine the mechanism(s) through which HIF and BAP1 regulate ISGF3. We found that in ccRCC cells, loss of the von Hippel-Lindau tumor suppressor (VHL) …

Effect Of Animal Stocking Density And Habitat Enrichment On Survival And Vitality Of Wild Green Shore Crabs, Carcinus Maenas, Maintained In The Laboratory, Charlotte H. Wilson, Russell C. Wyeth, John I. Spicer, Iain J. Mcgaw

School of Biological and Marine Sciences

The wide geographic distribution, large size and ease of capture has led to decapod crustaceans being used extensively in laboratory experiments. Recently in the United Kingdom decapod crustaceans were listed as sentient beings, resulting in their inclusion in animal care protocols. Ironically, little is known about how captive conditions affect the survival and general condition of wild decapod crustaceans. We used the green shore crab, Carcinus maenas, to investigate the effects of stocking density and shelter on survival and vitality indices during a 6 month period in the laboratory. Neither stocking density nor the presence of shelter affected survival. Stocking …

Relevance And Equality: An Analytical Account, Pedro Moniz Lopes

The Journal of Contemporary Legal Issues

In day-to-day life, one is compelled to compare. In replying to a question on one’s favorite things, one will group them together based on the satisfaction one is provided with, leaving out the rest. In discussing the issue of spiteful people, one is promptly reminded of some common features of individuals whose actions typically meet the required criteria (or the criteria one sets for such category). In metaphorical speech—for instance, by descriptively asserting that “no man is an island”—one grounds the assertion on past knowledge of the prototypical isolation of islands to, then, negate the transfer of such features to …
