Relative abundance of amphibians in forest canopy gaps of natural origin vs. timber harvest origin.— Small–scale canopy gaps created by logging may retain adequate habitat structure to maintain amphibian abundance. We used pitfalls with drift fences to measure relative abundance of amphibians in 44 harvested gaps, 19 natural treefall gaps, and 36 closed–canopy forest plots. Metamorphs had relatively lower capture rates in large harvest gaps for Ambystoma maculatum, Lithobates catesbeianus, L. clamitans, and L. sylvaticus but we did not detect statistically significant (p < 0.1) differences among gap types for Lithobates palustris metamorphs. L. clamitans juveniles and L. sylvaticus juveniles and adults had relatively lower ...

Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman III, Rebecca F. Hazen 2010 Wright State University - Main Campus

Diversity Of Interactions: A Metric For Studies Of Biodiversity, Lee A. Dyer, Thomas R. Walla, Harold F. Greeney, John O. Stireman Iii, Rebecca F. Hazen

Biological Sciences Faculty Publications

Multitrophic interactions play key roles in the origin and maintenance of species diversity, and the study of these interactions has contributed to important theoretical advances in ecology and evolutionary biology. Nevertheless, most biodiversity inventories focus on static species lists, and prominent theories of diversity still ignore trophic interactions. The lack of a simple interaction metric that is analogous to species richness is one reason why diversity of interactions is not examined as a response or predictor variable in diversity studies. Using plant-herbivore-enemy trophic chains as an example, we develop a simple metric of diversity in which richness, diversity indices (e ...


Tillage And Crop Residue Affect Irrigation Requirements, Simon van Donk 2010 University of Nebraska-Lincoln

Tillage And Crop Residue Affect Irrigation Requirements, Simon Van Donk

West Central Research and Extension Center, North Platte

Practicing less tillage and retaining more crop residue on the soil surface can reduce the rate of evaporation of water from the soil. These practices also increase the amount of soil water by increasing the amount of water that infiltrates into the soil and decreasing the amount that runs off across the soil surface. Less tillage and more residue coverage can significantly reduce the amount of irrigation water needed to grow a crop.

Genetic Characteristics And Environmental Parameters For Growing Turfgrass In Closed And Retractable Dome Stadiums, Bruce Bugbee, Paul Johnson 2010 Utah State University

Genetic Characteristics And Environmental Parameters For Growing Turfgrass In Closed And Retractable Dome Stadiums, Bruce Bugbee, Paul Johnson

Turfgrass

Our analysis indicates that electric lighting for turfgrass growth is highly cost effective, if it is coupled with appropriate genetic and environmental changes.

Inadequate light levels for vigorous turf growth is the key challenge associated with growing turf in enclosed and retractable dome stadiums. The light levels of closed stadiums are too low to maintain vigorous plant growth that can quickly recover from the damage caused by athletic events. As a solution, retractable-dome stadiums have been built. However, even with the roof open, light levels in these stadiums are less than half of natural sunlight because of shading from the ...


Role Of Drosophila Rap/Fzr (Cdh1) In Retinal Axon Targeting And Its Interactions With Loco, Liprin-A And Ras, Marta Gronska 2010 CUNY City College

Role Of Drosophila Rap/Fzr (Cdh1) In Retinal Axon Targeting And Its Interactions With Loco, Liprin-A And Ras, Marta Gronska

Master's Theses

The development of the wild type Drosophila compound eye involves stereotypical targeting of photoreceptor axons to the specific layers of the optic ganglion, medulla and lamina, in the third instar larvae. To test the hypothesis that ubiquitin ligases play an important role during retinal axon targeting we have examined the patterns of axon targeting in the developing eye of the retina aberrant in pattern (rap/fzr) mutants. Rap/Fzr is a homolog of mammalian Cdh1, an activator of anaphase promoting complex (APC), an E3 ubiquitin ligase. Previous work has shown that Rap/Fzr is required in cell cycle regulation, glia ...

The Influence Of Stored Product Mites On The Function Of Skin Microvascular Endothelial Cells, Jennifer Graff Curp

Browse all Theses and Dissertations

The prevalence of allergenic diseases and sensitization to stored product mites is increasing worldwide. Stored product mites are prevalent in homes, foods, and some work environments. Stored product mites need to be further studied so we can characterize their inflammatory properties to understand their role in skin disease, and provide proper treatment to patients with mite allergies. The purpose of the study was to show the role of stored product mites in modulating the inflammatory and immune response to human dermal endothelial cells in the skin. The epidermis serves as the first line of defense between the body and the ...

Browse all Theses and Dissertations

The neotropics harbor an enormous diversity of tachinid flies, yet the fauna remains poorly known. The tribe Blondeliini is particularly diverse in this region and desperately needs taxonomic attention. Here, I present a revision of the neotropical genus Erythromelana Townsend including the redescription of three previously described species and the description of 11 new species. Two species previously assigned into this genus, are resurrected as distinct genera. Erythromelana species are widely distributed from southern Mexico to northern Argentina, with the Andes being a hotspot of diversity. Erythromelana are specialized on geometrids in the genus Eois, which mainly feed on plants ...


Inhibition Of Cell Invasion By Targeting Pld, Terry C. Farkaly 2010 Wright State University

Inhibition Of Cell Invasion By Targeting Pld, Terry C. Farkaly

Browse all Theses and Dissertations

Phospholipase D (PLD) is a crucial signaling enzyme involved in many cellular processes. The catalytic activity of PLD is essential for the production of Phosphatidic Acid (PA), a critical second messenger in cell signaling cascades downstream. Using the highly invasive rat mammary adenocarcinoma cell line mTLn3 as a metastatic model, we investigated the proficiency of these cells to invade using matrigels that mimic the basement membrane of the extracellular matrix (ECM), their activity through PLD enzymatic assays, as well as the potency of our potential inhibitors to inhibit PLD-mediated cell invasion and lipase activity. This study reveals that PLD-mediated cell ...


Cellular And Molecular Dissection Of Pluripotent Adult Somatic Stem Cells In Planarians, Norito Shibata, Labib Rouhana, Kiyokazu Agata 2010 Wright State University - Main Campus

Cellular And Molecular Dissection Of Pluripotent Adult Somatic Stem Cells In Planarians, Norito Shibata, Labib Rouhana, Kiyokazu Agata

Biological Sciences Faculty Publications

Freshwater planarians, Plathelminthes, have been an intriguing model animal of regeneration studies for more than 100 years. Their robust regenerative ability is one of asexual reproductive capacity, in which complete animals develop from tiny body fragments within a week. Pluripotent adult somatic stem cells, called neoblasts, assure this regenerative ability. Neoblasts give rise to not only all types of somatic cells, but also germline cells. During the last decade, several experimental techniques for the analysis of planarian neoblasts at the molecular level, such as in situ hybridization, RNAi and fluorescence activated cell sorting, have been established. Moreover, information about genes ...


Antipredatory Defense Of Neonatal Pronghorn (Antilocapra Americana) By Yearling Male Pronghorn In Southwestern South Dakota, Christopher N. Jacques, Jonathan A. Jenks 2010 Wisconsin Department of Natural Resources

Antipredatory Defense Of Neonatal Pronghorn (Antilocapra Americana) By Yearling Male Pronghorn In Southwestern South Dakota, Christopher N. Jacques, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Antipredatory defense of pronghorn (Antilocapra americana) neonates (≤1 month old) by adult females (>18 months old) is well documented throughout the geographic range of this species. However, reports of male pronghorn defending neonates against predators are limited to a single study in northwestern Wyoming where occurrences were documented of adult males assisting female pronghorn in defending neonates against coyotes (Canis latrans). To our knowledge, defense of neonatal pronghorn by yearling males (12–18 months old) has not been reported previously for this species. We report occurrences of antipredatory defense of neonatal pronghorn by yearling males in southwestern South Dakota

The Influence Of Didymosphenia Geminate On Fisheries Resources In Rapid Creek, South Dakota – An Eight Year History, D.A. James, S.R. Chipps

Natural Resource Management Faculty Publications

The aquatic nuisance diatom Didymosphenia geminata was established in Rapid Creek in the Black Hills of South Dakota in 2002. Shortly thereafter, large declines (>50%) of the naturalized brown trout Salmo trutta population were observed. We evaluated the influence of water resources and D. geminata on (1) declines in brown trout biomass, (2) changes in food resources, and (3) diet of brown trout in Black Hills streams. Drought conditions were largely responsible for trout declines in Black Hills streams. However, comparison of brown trout sizestructure between the pre-D. geminata and post-D. geminata periods revealed that juvenile brown trout ...

Migration Of Northern Yellowstone Elk: Implications Of Spatial Structuring, P. J. White, Kelly M. Proffitt, L. David Mech, Shaney B. Evans, Julie A. Cunningham, Kenneth L. Hamlin 2010 National Park Service

Migration Of Northern Yellowstone Elk: Implications Of Spatial Structuring, P. J. White, Kelly M. Proffitt, L. David Mech, Shaney B. Evans, Julie A. Cunningham, Kenneth L. Hamlin

USGS Northern Prairie Wildlife Research Center

Migration can enhance survival and recruitment of mammals by increasing access to higher-quality forage or reducing predation risk, or both. We used telemetry locations collected from 140 adult female elk during 2000– 2003 and 2007–2008 to identify factors influencing the migration of northern Yellowstone elk. Elk wintered in 2 semidistinct herd segments and migrated 10–140 km to at least 12 summer areas in Yellowstone National Park (YNP) and nearby areas of Montana. Spring migrations were delayed after winters with increased snow pack, with earlier migration in years with earlier vegetation green-up. Elk wintering at lower elevations outside YNP ...


Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff 2010 USGS Northern Prairie Wildlife Research Center

Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff

USGS Northern Prairie Wildlife Research Center

Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son.With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this packmate ...


Mzm1 Influences A Labile Pool Of Mitochondrial Zinc Important For Respiratory Function, Aaron Atkinson, Oleh Khalimonchuk, Pamela Smith, Hana Sabic, David Eide, Dennis R. Winge 2010 University of Utah Health Sciences

Mzm1 Influences A Labile Pool Of Mitochondrial Zinc Important For Respiratory Function, Aaron Atkinson, Oleh Khalimonchuk, Pamela Smith, Hana Sabic, David Eide, Dennis R. Winge

Biochemistry -- Faculty Publications

Zinc is essential for function of mitochondria as a cofactor for

several matrix zinc metalloproteins. We demonstrate that a

labile cationic zinc component of low molecular mass exists in

the yeast mitochondrial matrix. This zinc pool is homeostatically

regulated in response to the cellular zinc status. This pool

of zinc is functionally important because matrix targeting of a

cytosolic zinc-binding protein reduces the level of labile zinc

and interferes with mitochondrial respiratory function. We

identified a series of proteins that modulate the matrix zinc

pool, one of which is a novel conserved mitochondrial protein

designated Mzm1. Mutant mzm1∆ cells have ...
