A Reassessment Of The Conservation Status Of A Critically Endangered Neotropical Frog, Mannophryne Olmonae, Using Occupancy Modeling Techniques, Jessica Mcquigg

Senior Independent Study Theses

Amphibian species worldwide are threatened with decline and extinction, making species monitoring an important scientific endeavor. The Bloody Bay Poison Frog, Mannophryne olmonae, a Tobago island endemic, was identified as critically endangered by the IUCN in 2004. Recent evidence suggests that a less severe conservation status may be appropriate for M. olmonae. This study employs acoustic calling surveys, land-use information, and multi-year (2011 and 2012) occupancy modeling techniques to propose an appropriate conservation status for this species. This study suggests that M. olmonae occupies a larger geographic range than was previously thought, and is not experiencing population declines. …

The Role Of Natural Products In Acidovorax Delafieldii Ath2-2rs/1 Survival In A Dry Formulation, David N. Thomas

Honors Theses

If rhizobacteria are to be used for weed biocontrol, a practical means of storing them must be found. In this project I sought to use the natural products exopolysaccharide and hydroxygectoine to improve the survival of Acidovorax delafieldii dry formulated with either an oat flour, maltose, and trehalose formulation or Celite (diatomaceous earth). When formulated with the oat flour, maltose, and trehalose, the expolysaccharide allowed for modest survival after 24 hours of drying. Using Celite, a preferred carrier, hydroxyectoine led to bacterial populations of 6.2 x 10(4) cells / g formulation after 24 hours of drying after 48 hours of …

Food Resource Availability For Carnaby's Cockatoo Calyptorhynchus Latirostris On The Swan Coast Plain, Teagan Johnston

Theses: Doctorates and Masters

To achieve a balance between sustainable development and conservation of threatened species, management depends on understanding the predicted response and interaction of that species with their environment in order to develop appropriate mitigating solutions. The Carnaby’s cockatoo Calyptorhynchus latirostris is declining across much of its range due to the detrimental effect of habitat degradation and loss. Since the decline of food resource availability in non-breeding areas is believed to be contributing to the reduction in the number of Carnaby’s cockatoos knowledge of the birds’ foraging ecology and the influence of external factors on food resource availability is essential for effective …

Working With Science Teachers To Transform The Opportunity Landscape For Regional And Rural Youth: A Qualitative Evaluation Of The Science In Schools Program, Grania R. Sheehan, Jennifer Mosse

Australian Journal of Teacher Education

This article reports on a qualitative evaluation of the Science in Schools program; a suite of science based activities delivered by staff of a regional university campus and designed to provide professional development for science teachers working in non-metropolitan schools in a socioeconomically disadvantaged region of Australia. The research identified a range of issues including: the influence of socioeconomic disadvantage and rurality on teachers’ professional learning needs, and the importance of subject specific discourse communities and content knowledge for new and out-of-field teachers. Implications for the design and implementation of school-university partnerships are discussed.

Knowledgeable Learning And Conceptual Change: Value Adding To Teacher Training, Tony Yeigh

Australian Journal of Teacher Education

This report concerns the use of pre and post responses to an online questionnaire as evidence of knowledgeable learning by education students at a regional Australian university. Factor analysis was used to reveal conceptual changes in the students’ thinking about classroom management across a unit of learning they had undertaken. These changes primarily involved movement from an authoritarian, rule-based management approach, toward a more differentiated, inclusive approach to management. The implications these changes have for unit delivery, as well as for validation of the engagement process, are discussed, and recommendations made concerning ongoing research and the design of online learning.

P900: A Putative Novel Erp Component That Indexes Counter-Measure Use In The P300-Based Concealed Information Test, John B. Meixner Jr., Elena Labkovsky, J. Peter Rosenfeld, Michael R. Winograd, Michael Winograd, Alexander Sokolovsky, Jeff Weishaar, Tim Ullmann

Scholarly Works

Countermeasures pose a serious threat to the effectiveness of the Concealed Information Test (CIT). In a CIT experiment, Rosenfeld and Labkovsky in Psychophysiology 47(6):1002–1010, (2010) observed a previously unknown positive ERP component at about 900 ms poststimulus at Fz and Cz that could potentially serve as an index of countermeasure use. Here, we explored the hypothesis that this component, termed P900, occurs in response to a signal that no further specific response is required in a trial, and could thus appear in countermeasure users that respond differentially depending on the stimulus that appears. In the present experiments, subjects viewed four …

3d Micron-Scale Imaging Of The Cortical Bone Canal Network In Human Osteogenesis Imperfecta (Oi), John R. Jameson, Carolyne Albert, Bjoern Busse, Peter A. Smith, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Osteogenesis imperfecta (OI) is a genetic disorder leading to increased bone fragility. Recent work has shown that the hierarchical structure of bone plays an important role in determining its mechanical properties and resistance to fracture. The current study represents one of the first attempts to characterize the 3D structure and composition of cortical bone in OI at the micron-scale. A total of 26 pediatric bone fragments from 18 individuals were collected during autopsy (N_c=5) or routing orthopaedic procedures (N_OI=13) and imaged by microtomography with a synchrotron light source (SRµCT) for several microstructural parameters including cortical porosity …

What Are The Mechanisms Of Action Of Stereotype Threat And How Does It Contribute To The Development Of Cardiovascular Disease In African Americans, Anthony Gage

Graduate Research Papers

The rate of hypertension and cardiovascular disease for African Americans is disproportionately higher compared to Whites Americans. Previous research has focused much of its attention on biological and socioeconomic differences as a pathway to explain the disparity in rates of cardiovascular disease. Reviewed is the connection between socioeconomic status and cardiovascular disease, but also extends the reach of etiology to include racially induced cardiovascular reactivity responses in African American. Stereotype threat occurs when a member of a stereotyped group encounters a situation where a stereotype exists, the threat of confirming the stereotype produces an exaggerated cardiovascular response. This model takes …

The Isolation And Characterisation Of Acientobacter Baumannii Bacteriophage, Mohamed Farag M. Elbreki

Theses

Acinetobacter baumannii is a pathogen, which has an increasing prevalence of multidrug resistance. It exists widely in natural environments, and frequently in health-care settings where it has proven difficult to eradicate using antibiotic therapy. A possible alternative to conventional antibiotics is the use of bacteriophages (phages) as antibacterials. In this project, extensive screening of environmental samples such as soils, sewage and waters was undertaken to identify suitable phages. Three phages were successfully isolated from municipal waste in the Cork area. These were subsequently characterized in detail and examined by electron microscopy, which showed that they were all of the Myoviridae …

Cumulative Response Of Ecosystem Carbon And Nitrogen Stocks To Chronic Co2 Exposure In A Subtropical Oak Woodland, Bruce A. Hungate, Paul Dijkstra, Zhuoting Wu, Benjamin D. Duval, Frank P. Day, Alisha L.P. Brown

Biological Sciences Faculty Publications

·Rising atmospheric carbon dioxide (CO₂) could alter the carbon (C) and nitrogen (N) content of ecosystems, yet the magnitude of these effects are not well known. We examined C and N budgets of a subtropical woodland after 11 yr of exposure to elevated CO₂.

·We used open-top chambers to manipulate CO₂ during regrowth after fire, and measured C, N and tracer ¹⁵N in ecosystem components throughout the experiment.

·Elevated CO₂ increased plant C and tended to increase plant N but did not significantly increase whole-system C or N. Elevated CO₂ increased soil …
