Improving The Instruction And Learning Of Topographic Maps Through The Use Of Geospatial Technologies, Troy Dean Schwemm

Dissertations and Theses @ UNI

Geographic information technologies (GIT) are spatially based technologies that include geographic information systems (GIS), remote sensing, and global positioning systems (GPS). Though GIT has been used in society for decades, and has grown tremendously in the last 10 years as advancements in technology have become available, its inclusion into the K-12 curriculum has not kept pace. As the educational reform movement places an ever increasing amount of pressure on schools to produce technologically literate, workforce ready graduates, school districts are scrambling to find creative, innovative ways to accomplish this task. Rather than learning passively, GIT allows students to construct their …

Ecological Niche Modeling Of Potential West Nile Virus Vector Mosquito Species In Iowa, Scott R. Larson, John P. Degroote, Lyric C. Bartholomay, Ramanathan Sugumaran

Faculty Work

Ecological niche modeling (ENM) algorithms, Maximum Entropy Species Distribution Modeling (Maxent) and Genetic Algorithm for Rule-set Prediction (GARP), were used to develop models in Iowa for three species of mosquito – two significant, extant West Nile virus (WNV) vectors (Culex pipiens L and Culex tarsalis Coquillett (Diptera: Culicidae)), and the nuisance mosquito, Aedes vexans Meigen (Diptera: Culicidae), a potential WNV bridge vector. Occurrence data for the three mosquito species from a state-wide arbovirus surveillance program were used in combination with climatic and landscape layers. Maxent successfully created more appropriate niche models with greater accuracy than GARP. The three Maxent species’ …

A Late-Quaternary Record Of Environmental Variability From Lake Sediment Cores, Wind River Range, Wyoming, Tyler Johnson

Dissertations and Theses @ UNI

Sediment cores from two alpine lakes in Wyoming's Wind River Range were collected and analyzed to establish a record of depositional and mineralogical variability. Due to the hydrologic setting and isolation of Fiddlers and Louis lakes, these cores yielded the longest continuous limnological record in the region that extends back nearly 20,000 years to full-glacial conditions, a rarity for alpine lakes in the western United States.

To develop a paleolimnological record for Fiddlers and Louis lakes, the sediment cores were analyzed using four laboratory techniques. These techniques included particle size analysis, x-ray diffraction, heavy mineral analysis, and loss-on-ignition. Radiocarbon ages …

Spatio-Temporal Cluster Analysis Of County-Based Human West Nile Virus Incidence In The Continental United States, Ramanathan Sugumaran, Scott R. Larson, John P. Degroote

Faculty Work

Background: West Nile virus (WNV) is a vector-borne illness that can severely affect human health. After introduction on the East Coast in 1999, the virus quickly spread and became established across the continental United States. However, there have been significant variations in levels of human WNV incidence spatially and temporally. In order to quantify these variations, we used Kulldorff's spatial scan statistic and Anselin's Local Moran's I statistic to uncover spatial clustering of human WNV incidence at the county level in the continental United States from 2002– 2008. These two methods were applied with varying analysis thresholds in order …

Think Like A Mountain : The Need For Nature For Increased Mental Health, Erin M. Mclaughlin

Graduate Research Papers

Nature has been an integral part of the human life for thousands of years. Only in the most recent hundred years, societies have begun to view nature as a foreign concept outside of the normal realm of daily life. Along with this disconnect from nature, mental illness has increased in our societal populations. This paper identifies the correlation of the need for nature, the lack of connection to nature, and the significant increase in depression, ADHD, anxiety, and autism diagnoses, among others. It also identifies therapeutic techniques that incorporate and connect with nature, as well as provides a comprehensive reference …

Development Of A Spatial Decision Support Tool For Watershed Critical Area Identification Of Soil Loss And Best Management Practices (Bmps) Evaluation, Luhua Cai

Dissertations and Theses @ UNI

Soil erosion has been identified as a major contributor to water quality degradation. Agriculture is historically known for accelerating soil erosion. In Iowa, with 88% of land in agriculture use, agricultural practices have became the dominant source of nonpoint source pollution and soil erosion is the leading water problem in Iowa. Controls of soil erosion are needed. Best Management Practices (BMPs) are recognized as the most efficient way to control non-point source pollution, and numerous BMPs have been developed for soil erosion control. Therefore, it is important to have a decision support tool that can identify the soil erosion problem …

Monitoring Spatial And Temporal Water Quality Changes In Iowa Lakes Using Airborne Hyperspectral Imagery, Nathan Robert Green

Dissertations and Theses @ UNI

The U.S. Environmental Protection Agency (US EPA) has identified more than 20,000 water bodies across America as polluted mainly due to agricultural non-point source pollution. Current techniques for monitoring and assessing the quality of waters in streams, reservoirs, lakes, and estuaries involve on site measurements and/or the collection of water samples for subsequent laboratory analyses. While this approach yields accurate measurements for a point in time and space, it is expensive, laborious, and cannot provide a temporal or spatial overview of water-quality trends. To overcome this liability, state and local agencies are seeking alternative and more cost effective methods. A …

Extraction Of Transportation Infrastructure From Hyperspectral Remote Sensing Data, James Paul Gerjevic

Dissertations and Theses @ UNI

The goal of this study was to extract transportation infrastructure features from hyper-spectral imagery using data from the high resolution Airborne Visible/Infrared Imaging Spectrometer (AVIRIS).
