Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza

Journal of the Arkansas Academy of Science

Like most species of Passiflora, P. lutea is reported to produce one-day flowers with complicated floral movements and requires deposition of non-self pollen for fruit production. Medium sized bees are the most likely pollinators in central Texas. We report on a series of observations and experimental manipulations that compare the reproductive biology of P. lutea in central Arkansas to that reported previously from plants about 800 km distant in central Texas. We observed floral movements and floral visitors, compared fruit production of flowers available to pollinators versus flowers from which pollinators were excluded, and compared fruit production of flowers that …

Algae In Agricultural Fields From St. Francis County, Arkansas, T. Smith

Journal of the Arkansas Academy of Science

On August 9th, 2007, two agriculture fields (rice and sorghum fields) were sampled for freshwater algae in St. Francis County. The purpose of this study was to document the algal species in the rice and sorghum fields and compare the similarities of species composition. There were a total of 53 species identified. Overall, diatoms and cyanobacteria were equally dominant with both represented by 21 species (39.6% of the total) and 11 green algal species (20.8%) were present. The sorghum field was dominated by Chlorogloeopsis fritschii and Chroococcus limneticus, while Anabeana cylindrica was abundant in the rice field.

Acidification And Stress Physiology In A Plethodontid Salamander, Desmognathus Ochrophaeus, Lauren Ricciardella

Electronic Theses and Dissertations

In western Pennsylvania, chronically and episodically acidified stream habitats are common. The mountain dusky salamander, Desmognathus ochrophaeus, is an abundant species that is associated with acidified streams. The focus of this research was to (1) examine the effects of acidified habitats on the stress hormone, corticosterone, and (2) examine the effects of corticosterone on behavior. In an acidified stream site, males had a blunted corticosterone stress response after capture and handling compared to an acid neutral site. There was a trend for elevated corticosterone to inhibit several aspects of male mating behavior, including insemination of females. These data suggest that …

Riparian Buffer Design Guidelines For Water Quality And Wildlife Habitat Functions On Agricultural Landscapes In The Intermountain West, Craig W. Johnson, Susan Buffler

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Intermountain West planners, designers, and resource managers are looking for science-based procedures for determining buffer widths and management techniques that will optimize the benefits riparian ecosystems provide. This study reviewed the riparian buffer literature, including protocols used to determine optimum buffer widths for water quality and wildlife habitat functions. We selected an existing protocol for determining buffer widths for water quality functions that could be readily adapted for use in this region. The protocol is based on the best available science, uses existing or easily obtained data, and is practical for in-field applications. The protocol was modified to accommodate Intermountain …

Discrete Return Lidar-Based Prediction Of Leaf Area Index In Two Conifer Forests, Jennifer L. R. Jensen, Karen S. Humes, Lee A. Vierling, Andrew T. Hudak

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Leaf area index (LAI) is a key forest structural characteristic that serves as a primary control for exchanges of mass and energy within a vegetated ecosystem. Most previous attempts to estimate LAI from remotely sensed data have relied on empirical relationships between field-measured observations and various spectral vegetation indices (SVIs) derived from optical imagery or the inversion of canopy radiative transfer models. However, as biomass within an ecosystem increases, accurate LAI estimates are difficult to quantify. Here we use lidar data in conjunction with SPOT5-derived spectral vegetation indices (SVIs) to examine the extent to which integration of both lidar and …

Conservation Buffers: Design Guidelines For Buffers, Corridors, And Greenways, Gary Bentrup

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Conservation Buffers: Design Guidelines for Buffers, Corridors, and Greenways

Over 80 illustrated design guidelines for conservation buffers are synthesized and developed from a review of over 1,400 research publications. Each guideline describes a specific way that a vegetative buffer can be applied to protect soil, improve air and water quality, enhance fish and wildlife habitat, produce economic products, provide recreation opportunities, or beautify the landscape. These science-based guidelines are presented as easy-to-understand rules-of-thumb for facilitating the planning and designing of conservation buffers in rural and urban landscapes.

Effects Of Habitat Disturbance On Survival Rates Of Softshell Turtles (Apalone Spinifera) In An Urban Stream, Michael Plummer, David G. Krementz, Larkin A. Powell, Nathan Mills

School of Natural Resources: Faculty Publications

We monitored Spiny Softshell Turtles (Apalone spinifera) using mark-recapture during 1994– 2005 in Gin Creek, Searcy, Arkansas. In 1997–2000 the creek bed and riparian zone were bulldozed in an effort to remove debris and improve water flow. This disturbance appeared to reduce the quantity and quality of turtle habitat. We tested for the potential effect of this habitat disturbance on the survival rates of marked turtles. We estimated annual survival rates for the population using models that allowed for variation in survival by state of maturation, year, and effects of the disturbance; we evaluated two different models of …

Marginalized Students' Perspectives Of School Consolidation: A Case Study In Rural West Virginia, Betty A. Sias

Theses, Dissertations and Capstones

While prior research provides evidence that school consolidation impacts student achievement, the economic efficiency at state and district levels, dropout rates, participation in extracurricular activities, curriculum offerings, and the length of bus rides, “little is known about what happens in consolidated schools to impact student learning,” (Blake, 2003, p. 21) and little attention has been given to studying students’ lived experiences of consolidation. This qualitative case study explored these issues by attempting to understand students’ transition to a consolidated high school, as well as their current experiences with and perceptions of consolidation in a rural community in West Virginia. The …

Unqualified Interests, Definitive Definitions: Washington V. Glucksberg And The Definition Of Life, Alexa Hansen

UC Law Constitutional Quarterly

In Washington v. Glucksberg, the Supreme Court upheld a Washington statute that forbade physician-assisted suicide under rational basis review. One of the articulated state interests was the state's "unqualified interest in preserving life." However, the Court neglected to define when life ends, which would mark the end of the state's unqualified interest. Without a definition for the end of life, the Court assumed its eventual conclusion: it is impossible for an individual interest to overcome an unqualified interest in an undefined term.

By adopting "whole brain death" as the definition of the end of life, the Court would provide a …

A Review Of The Literature On Mathematics And Science Teacher Quality, Johnna J. Bolyard, Patricia S. Moyer-Packenham

Teacher Education and Leadership Faculty Publications

A large body of literature exists that examines teacher quality characteristics and the relationship of indicators of those characteristics to teacher effectiveness. This existing research literature broadly views teacher quality research without illuminating specific areas of teacher quality, such as mathematics and science. In an effort to focus the literature base for researchers and policymakers more narrowly, this review specifically examines teacher quality as it relates to mathematics and science teaching and learning. The review highlights key policy and practitioner perspectives, provides a focused synthesis on current research findings on mathematics and science teacher quality, and suggests areas of research …

The Education Of Students With Emotional And Behavioral Disorders In Today's Schools, Matthew Spreter

Education Masters

One of the most controversial issues in Special Education today is the placement of students with Emotional and Behavioral Disorders (FJBD). Many professionals support inclusion of students with EJBD into the general education environment, while others take a more conservative approach. In order to evaluate educational placement of students with EJBD, research from journal articles and text was conducted to determine if there was any consensus among professionals in the field. The researcher interviewed a number of school professionals, representative of those who might make up a Committee for Special Education (CSE). It was deemed important to hear from real …

Estimating Maximum Performance: Effects Of Intraindividual Variation, Stephen C. Adolph, Trevor Pickering '05

All HMC Faculty Publications and Research

Researchers often estimate the performance capabilities of animals using a small number of trials per individual. This procedure inevitably underestimates maximum performance, but few studies have examined the magnitude of this effect. In this study we explored the effects of intraindividual variation and individual sample size on the estimation of locomotor performance parameters. We measured sprint speed of the lizard Sceloporus occidentalis at two temperatures (20 degrees C and 35 degrees C), obtaining 20 measurements per individual. Speed did not vary temporally, indicating no training or fatigue effects. About 50% of the overall variation in speed at each temperature was …

A Model For Rolling Swarms Of Locusts, Chad M. Topaz, Andrew J. Bernoff, Sheldon Logan '06, Wyatt Toolson '07

All HMC Faculty Publications and Research

We construct an individual-based kinematic model of rolling migratory locust swarms. The model incorporates social interactions, gravity, wind, and the effect of the impenetrable boundary formed by the ground. We study the model using numerical simulations and tools from statistical mechanics, namely the notion of H-stability. For a free-space swarm (no wind and gravity), as the number of locusts increases, the group approaches a crystalline lattice of fixed density if it is H-stable, and in contrast becomes ever denser if it is catastrophic. Numerical simulations suggest that whether or not a swarm rolls depends on the statistical mechanical properties of …
