Possible relationship between vocal communication system and fat reserve in wintering birds: a test of the optimal body mass theory
(Wichita State University, 2017-12)Fat reserve is a key adaptation in wintering small birds for maximizing individual fitness in a variable environment. Optimal body mass models suggest that winter fat reserve maximizes winter survival by balancing costs, ... -
Proteomic assessment of human ovarian cancer cell lines xenotransplanted into the hamster cheek pouch
(Wichita State University, 2014-07)Ovarian cancer, commonly arises from the surface epithelium, remains the fifth common cause of cancer death in women and the most lethal of gynecological cancers. One reason for such lethality is that the disease is seldom ... -
Proteomic assessment of pharynx (FADU) and tongue (CAL27) cell lines of head and neck squamous cell cancer
(Wichita State University, 2019-12)Head and neck cancer are the sixth most common cancer worldwide and its diagnostic rate is approximately 630,000 new patients a year with more than 350,000 deaths every year. The majority (approximately 90%) of head and ... -
Reassessment of intra- and extra-ovarian expression of growth differentiation factor-9
(2006-05)Mammalian ovarian organogenesis is characterized temporally by oogonial mitosis, oogonial apoptosis, rescue of germ cells via interaction with somatic cells to form primordial follicles, and entrance into meiosis. Recent ... -
Reducing invasion by targeting vulnerable life stages: effects of fire on survivorship of Lespedeza cuneata
(Wichita State University, 2011-12)There is growing interest in whether invasive species may be controlled by targeting key life stages or by tailoring different management strategies to the specific characteristics of particular life stages. In this study, ... -
Relative experimental effects of exogenous and endogenous heterogeneity on plant community composition during community assembly
(Wichita State University, 2021-05)Species diversity is expected to increase with environmental heterogeneity, and this pattern has been confirmed by numerous observational studies. For plants, this spatial heterogeneity is likely driven by differences in ... -
Response of aquatic microinvertebrates within isolated tallgrass prairie stream pools to experimental drying
(Wichita State University, 2021-07)Intermittent streams experience varying drying and rewetting cycles that influence the organisms that are able utilize these systems. These disturbance regimes are expected to be greatly impacted by climate change and other ... -
Reversing songbird decline: The effect of food supplementation on the overwinter survival of the dark-eyed junco (Junco hyemalis)
(Wichita State University, 2014-07)Decline of songbirds is widespread in North America. Habitat loss, fragmentation, and degradation are hypothesized to be a primary cause of avian decline. The Dark-eyed Junco (Junco hyemalis), a granivorous, migratory ... -
The role of altered microRNA expression in an experimental model of estrogen-dependent uterine cancer
(Wichita State University, 2009-07)This project screened for altered expression of small RNA species, microRNAs (miRNA), in the hamster uterus following neonatal exposure to the potent synthetic estrogen and established endocrine disruptor diethylstilbestrol ... -
The role of auxin in the compatible interaction between macrophomina phaseolina and its plant host medicago truncatula
(Wichita State University, 2012-05)Macrophomina phaseolina (M. phaseolina) is a soil-borne fungal pathogen that causes charcoal rot disease in many plant species. This disease causes many problems to the soy industry as no consistently effective control is ... -
Soil community analysis along a salt gradient using denaturing gradient gel electrophoresis of PCR-amplified 16s rRNA genes
(2006-05)Many studies of hyper saline environments have been performed, mainly on aquatic systems. However, the microbial community in terrestrial thallasohaline environments has not been studied extensively. To our knowledge, this ... -
Study of charcoal rot disease using the model plant Arabidopsis Thaliana
(Wichita State University, 2013-07)Macrophomina phaseolina is a warm climate fungal pathogen of the Botryosphaeriaceae family that causes charcoal rot disease in over 700 plant species including commercially grown plants such as soybean, maize, peanut and ... -
Sucretolerance in oligosaline soils and halotolerant bacteria
(Wichita State University, 2014-12)It is well established that microbial growth is decreased with the reduction of available water in a given environment. The availability of water is referred to as water activity and is expressed in aw values, that provide ... -
Suppression of growth of the Phytopathogenic Fungus Macrophomina Phaseolina through application of Exogenous Sirnas
(Wichita State University, 2019-07)Macrophomina phaseolina, causative agent of the plant disease charcoal rot, impacts over 500 plant species, causing devastating crop failures worldwide. In Kansas, it is the biggest cause of soybean crop loss, and disease ... -
The effects of Batrachochytrium dendrobatidis and sub-lethal nitrate concentrations on Xenopus laevis
(Wichita State University, 2013-12)The pathogenic fungus Batrachochytrium dendrobatidus (Bd) is responsible for mass disruption of amphibian species and causes the disease known as chytridiomycosis which disrupts the amphibian skin resulting in high mortality ... -
The influence of soil heterogeneity on plant species richness
(Wichita State University, 2013-12)Environmental heterogeneity is often cited as one of the driving mechanisms behind community species composition and diversity. However, its contribution to species composition in plant communities remains unclear because ... -
The investigation of regulation of glioma cell migration in a three-dimensional model
(Wichita State University, 2017-12)The invasion of glioblastoma is a complex process that involves coordinated interactions between tumor cells and the extracellular matrix. Biomaterial scaffolds now show promise in forming in vitro and in vivo three-dimensional ... -
The link between susceptibility to Macrophomina phaseolina and three phytohormones in Medicago truncatula
(Wichita State University, 2015-07)Macrophomina phaseolina is a major agricultural pest causing the disease charcoal rot in many species of crops. The disease manifests as yellowing (chlorosis) and death (necrosis) of plant tissue by secreting plant toxins ... -
