Determining whether mate-searching males use directional information from female signals in Umbonia crassicornis
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
signals do influence the paths that males take to find females. Our results will guide future research on the actual mechanisms used by treehoppers to determine the direction of a substrate vibration and will continue to provide important insights...

The ramosa1 gene plays a role in shoot-borne root patterning in Zea mays L.
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
to tassels indicating that the role of ra1 may differ depending developmental phase. This research was supported by the NSF UMEB Program, Life Science Mission Enhancement, and USDA ARS....
Differential effects of the components of higher education expenditure on U.S. state economic growth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
externalities as was previously expected. On one hand, some scholars argue that greater public funding on education is needed to increase labor force productivity. On the other hand, research indicates that the cost of human capital investment has increased...
Photolytically-controlled release of dexamethasone [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
photolytically labile molecule. Prior to this, we characterized the diffusion of dex within our hydrogel network. Our experiments demonstrated that we could achieve controlled release of dex wih varying light intensity and it should thus be possible to achieve...
Biotope mapping to compare and contrast Columbia, Missouri neighborhoods
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
How people manage their property can ultimately have an affect on biodiversity, and ecosystem services. Our project seeks to understand the relationship of socioeconomic status to property management and how it affects ...
The impacts of floral fragrances and ant contamination on pollinator behavioral responses
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
World economy, including agriculture and food production, is heavily dependant on animal pollination. For this reason, it is important to understand factors that mediate plant-pollinator interactions. We investigated ...
Resolution of phylogenetic patterns within the angiosperm order Asparagales [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The angiosperm order Asparagales, is an economically important monocot order that includes onions (Allium), asparagus (Asparagus), and agaves (Agave). The core Asparagales includes ten families that form a monophyletic ...
Population trends of forest birds in Missouri, USA: Comparison of point count data with predictions from the BBS [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Long-term population size trends of Neotropical migrants and other forest birds are of primary concern for conservation biologists. The Breeding Bird Survey (BBS) has become an important tool for biologists in estimating ...
The effects of leaf litter type on the growth and development of gray treefrog tadpoles
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Forestry practices are implemented worldwide to manage tree populations and harvest resources. Forestry practices involve the thinning and/or intentional planting of trees which influences canopy cover and litter species. ...
Evaluating the relationship between leaf nitrogen concentration and Minolta SPAD-502 meter readings [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Oak trees are deciduous trees that can live for up to 200 years and face a variety of environmental stresses. Like all plants, oak trees need nutrients, which vary under different stress conditions. We study nitrogen as ...
The influence of increased contact rate among raccoons on a nematode of public, and wildlife health concern, Baylisascar [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Natural and anthropogenic fluctuations in resource availability can alter the behavioral ecology and population dynamics of wildlife. This may have unintended consequences to wildlife disease ecology, as theoretical models ...
Assessing the value of agricultural streams as amphibian refuges [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Although many causes for worldwide amphibian population declines are under investigation, the destruction and alteration of aquatic habitats remains a primary threat. In agricultural landscapes, natural wetlands are often ...
An evaluation of long term changes in clear-cuts and plantations in Mid-Missouri
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Identifying future stand composition is important for several reasons including: aesthetics, wildlife benefits, timber value, and predicting potential changes. I studied the species composition in the over story and the ...
Vegetation classification in urban nature areas in Columbia, Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Urban nature areas are often identified by local governments with no thought to their ecological characteristics or conservation value. We used a vegetation classification procedure, entitation, to classify vegetation types ...
The manifestation of death in Nathaniel Hawthorne's gothic fiction [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Nathaniel Hawthorne is one of the most popular authors of American literature during the 19th century. My research then investigates how Nathaniel Hawthorne's “Alice Doane's Appeal” as well as “The House of Seven Gables” engage with the gothic genre...
Acadian Flycatcher nest placement: A strategy of survival
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Due to recent population declines, the reproductive success of neotropic migratory birds has become a prime research target. Predator-prey interaction, namely nest predation, has been shown to be the leading cause of nest failure of many avian...
Functional analysis of various conserved domains of NPH3 involved in phototropism in Arabidopsis thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Phototropism - the directional growth (curvature) for a plant towards light, is a very important adaptive response in plants in order for them to maximize photosynthesis. Blue light triggers phototropic response in Arabidopsis ...
Using a candidate gene approach to identify the restorer-of-fertility Rf4 gene for maize CMS-C
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Cytoplasmic male sterility (CMS) is a maternally inherited trait that prevents normal pollen development. Although CMS is a mitochondrial mutation, there are nuclear genes known as restorer-of-fertility genes (Rf) that ...
