Maxent Modeling For Predicting Potential Distribution Of Goitered Gazelle In Central Iran: The Effect Of Extent And Grain Size On Performance Of The Model, Rasoul Khosravi, Mahmoud Reza Hemami, Mansoureh Malekian, Alan Flint, Lorraine Flint Jan 2016

Maxent Modeling For Predicting Potential Distribution Of Goitered Gazelle In Central Iran: The Effect Of Extent And Grain Size On Performance Of The Model, Rasoul Khosravi, Mahmoud Reza Hemami, Mansoureh Malekian, Alan Flint, Lorraine Flint

Turkish Journal of Zoology

The spatial scale of environmental layers is an important factor to consider in developing an understanding of ecological processes. This study employed Maxent modeling to investigate the geographic distribution of goitered gazelle, Gazella subgutturosa (Güldenstädt, 1780), in central Iran using uncorrelated variables at a spatial resolution of 250 m. We used spatial downscaling to downscale WorldClim data to 250-m resolution. We evaluated the sensitivity of the model to different grain and extent sizes from 250 m to 3 km. We compared the performance of the model at different scales using suitability indexes (AUC) and predicted habitat areas. Two models performed …


Spatial And Temporal Variations Of Screening For Breast And Colorectal Cancer In The United States, 2008 To 2012, Xue Feng, Xi Tan, Ebtihag Alenzi, Pragya Rai, Jongwha Chang Jan 2016

Spatial And Temporal Variations Of Screening For Breast And Colorectal Cancer In The United States, 2008 To 2012, Xue Feng, Xi Tan, Ebtihag Alenzi, Pragya Rai, Jongwha Chang

Faculty & Staff Scholarship

Cancer screening tests are important tools to combat cancer-related morbidity and mortality. There is limited up-to-date research on spatial and temporal variations of colorectal and breast cancer screening in the United States.

County-level data of cancer screening adherence rates were generated from 2008 to 2012 Behavioral Risk Factor Surveillance System. We performed the univariate local indicators for spatial analyses (LISA) for the geographic differences of screening adherence rate and the differential LISA for the change of screening adherence rate from 2008 to 2012.

In the univariate LISA, low-to-low clusters were consistently identified in counties of New Mexico, Wyoming, and Mississippi …


The Association Between Graduated Driver Licensing Laws And Travel Behaviors Among Adolescents: An Analysis Of Us National Household Travel Surveys, Motao Zhu, Peter Cummings, Songzhu Zhao, Thomas Rice Jan 2016

The Association Between Graduated Driver Licensing Laws And Travel Behaviors Among Adolescents: An Analysis Of Us National Household Travel Surveys, Motao Zhu, Peter Cummings, Songzhu Zhao, Thomas Rice

Faculty & Staff Scholarship

Background: Young novice drivers have crash rates higher than any other age group. To address this problem, graduated driver licensing (GDL) laws have been implemented in the United States to require an extended learner permit phase, and create night time driving or passenger restrictions for adolescent drivers. GDL allows adolescents to gain experience driving under low-risk conditions with the aim of reducing crashes. The restricted driving might increase riding with parents or on buses, which might be safer, or walking or biking, which might be more dangerous. We examined whether GDL increases non-driver travels, and whether it reduces total travels …


White-Tailed Deer (Odocoileus Virginianus) Subsidize Gray Wolves (Canis Lupus) During A Moose (Alces Americanus) Decline: A Case Of Apparent Competition?, Shannon M. Barber-Meyer, L. David Mech Jan 2016

White-Tailed Deer (Odocoileus Virginianus) Subsidize Gray Wolves (Canis Lupus) During A Moose (Alces Americanus) Decline: A Case Of Apparent Competition?, Shannon M. Barber-Meyer, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Moose (Alces americanus) in northeastern Minnesota have declined by 55% since 2006. Although the cause is unresolved, some studies have suggested that Gray Wolves (Canis lupus) contributed to the decline. After the Moose decline, wolves could either decline or switch prey. To determine which occurred in our study area, we compared winter wolf counts and summer diet before and after the Moose decline. While wolf numbers in our study area nearly doubled from 23 in winter 2002 to an average of 41 during winters 2011–2013, calf:cow ratios (the number of calves per cow observed during winter …


Patuxent’S Long-Term Research On Wolves, L. David Mech Jan 2016

Patuxent’S Long-Term Research On Wolves, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The gray wolf (Canis lupus) was one of the first species placed on the Endangered Species List in 1967. The Endangered Species Act of 1973 legally protected the wolf along with other listed species.

Patuxent Wildlife Research Center (Patuxent) in Laurel, MD, began its Endangered Wildlife Program in 1966, and U.S. Fish and Wildlife Service (USFWS) biologist Ray Erickson was assigned to lead it. In 1973, I was transferred to the program from Region 3 of the USFWS, having been employed there since 1969 to study wolves in Minnesota.

Endangered Species Act protection of the wolf fostered its quick …

Determinants Of Spread In An Urban Landscape By An Introduced Lizard, Jason J. Kolbe, Paul Vanmiddlesworth, Andrew C. Battles, James T. Stroud, Bill Buffum, Richard T. T. Forman, Jonathan B. Losos

Biological Sciences Faculty Publications

Context: Urban landscapes are a mixture of built structures, human-altered vegetation, and remnant semi-natural areas. The spatial arrangement of abiotic and biotic conditions resulting from urbanization doubtless influences the establishment and spread of non-native species in a city.

Objectives: We investigated the effects of habitat structure, thermal microclimates, and species coexistence on the spread of a non-native lizard (Anolis cristatellus) in the Miami metropolitan area of South Florida (USA).

Methods: We used transect surveys to estimate lizard occurrence and abundance on trees and to measure vegetation characteristics, and we assessed forest cover and impervious surface using GIS. We …


A Comparative Study Of The Flora And Soils Of Great Duck And Little Duck Islands, Maine, Usa, Luka Negoita, Matthew Dickinson, Glen Mittelhauser, Nishanta Rajakaruna Jan 2016

A Comparative Study Of The Flora And Soils Of Great Duck And Little Duck Islands, Maine, Usa, Luka Negoita, Matthew Dickinson, Glen Mittelhauser, Nishanta Rajakaruna

Faculty Publications, Biological Sciences

Strong environmental gradients and varied land-use practices have generated a mosaic of habitats harboring distinct plant communities on islands on the coast of Maine. Botanical studies of Maine's islands, however, are generally limited in number and scope. Baseline studies of Maine's islands are necessary for assessing vegetation dynamics and changes in habitat conditions in relation to environmental impacts imposed by climate change, rising sea levels, invasive species, pests and pathogens, introduced herbivores, and human disturbance. We conducted a survey of the vascular plants and soils of forest, field, and ocean-side communities of Great Duck and Little Duck Islands, ME. These …

03. Population Demographics Of The Loggerhead Shrike: Insights Into The Species Decline From A Long-Term Study In The Midewin National Tallgrass Prairie, Amy A. Chabot, Fran Harty, James Herkert, William Glass

North American Prairie Conference Proceedings

We monitored a breeding population of loggerhead shrikes (Lanius ludovicianus) in the Midewin National Tallgrass Prairie from 2005 to 2016. Demographic data were compiled annually, including information on population size, age structure, and reproductive success. We banded adult shrikes, with some additional effort focused on nestlings (2005–2007) and independent hatch-year birds (2014–2016). We measured return rate as the number of birds that were previously banded. Site reuse rates were quantified as the use of a breeding territory in multiple years. Site fidelity, the use of a site by the same male or female in consecutive years, and dispersal distance of …


The Spatial Distribution Of Terrestrial Stable Carbon Isotopes In North America, And The Impacts Of Spatial And Temporal Resolution On Static Ecological Models, Sydney M. Firmin Jan 2016

The Spatial Distribution Of Terrestrial Stable Carbon Isotopes In North America, And The Impacts Of Spatial And Temporal Resolution On Static Ecological Models, Sydney M. Firmin

Electronic Theses and Dissertations

Due to the unique spatial and temporal characteristics of ecological phenomena, the extent and grain size of spatial data sets essentially filter the observations. This thesis examines the impacts of temporal and spatial resolution on the modeling of terrestrial stable carbon isotopic landscapes (isoscapes). I model the distribution of leaf stable carbon isotope composition (delta13C) for the continent of North America at multiple temporal and spatial resolutions. I generate each delta13C isoscape variation by first predicting the relative abundance of C3/C4 vegetation cover using monthly climate grids, crop distribution/type grids, and remote sensing data of plant …


Serum Chemistry, Blood Gas, And Physiological Measures Of Sandhill Cranes Sedated With Alpha-Chloralose, Richard R. Sim, Barry K. Hartup Jan 2016

Serum Chemistry, Blood Gas, And Physiological Measures Of Sandhill Cranes Sedated With Alpha-Chloralose, Richard R. Sim, Barry K. Hartup

Proceedings of the North American Crane Workshop

Capture techniques that lessen handling stress may also lessen pathologic influences on physiologic measures, improving the validity of these measures for use in individual health assessment of freeranging wildlife. Since 1990, the International Crane Foundation (ICF) has successfully used chemical immobilization with alpha-chloralose (AC; C6H11Cl3O6), a chloral derivative of glucose, to facilitate captures of sandhill cranes (Grus canadensis tabida) for ecological studies (Hayes et al. 2003). Although this chemical has been used orally for the immobilization of many species, the physiologic effects of AC are not well understood in cranes. …

Major: Curriculum and Instruction

Degree: Doctor of Philosophy

There has been great debate about the reasons why African American male students reject the institution of school and school related content. Furthermore, data from multiple sources, including, national and local assessments and governmental studies, document a gap in achievement and school retention rates between African American students and their White counterparts. The data substantiates the notions that African American males have an aversion …


Endangered Species Research In Hawaii: The Early Years (1965–87), Michael J. Scott, Cameron B. Kepler Jan 2016

Endangered Species Research In Hawaii: The Early Years (1965–87), Michael J. Scott, Cameron B. Kepler

United States Geological Survey: Staff Publications

Hawaii is an ecologically isolated archipelago 2,500 miles from the nearest continent. Its isolation resulted in a taxonomically unbalanced flora and fauna with remarkable examples of adaptive radiation among those groups of organisms that won the dispersal sweepstakes. It was one of the last oceanic island groups to be populated by humans, about 900 A.D. by Polynesian travelers and in 1778 by Europeans. Relatively recent colonization by humans did not save it, however, from the biodiversity losses suffered by other isolated archipelagos—it only delayed them (Scott and others, 1988; Pratt and others, 2009a).


The Influence Of A Severe Reservoir Drawdown On Springtime Zooplankton And Larval Fish Assemblages In Red Willow Reservoir, Nebraska, Jason A. Deboer, Christa M. Webber, Taylor A. Dixon, Kevin L. Pope Jan 2016

The Influence Of A Severe Reservoir Drawdown On Springtime Zooplankton And Larval Fish Assemblages In Red Willow Reservoir, Nebraska, Jason A. Deboer, Christa M. Webber, Taylor A. Dixon, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Reservoirs can be dynamic systems, often prone to unpredictable and extreme waterlevel fluctuations, and can be environments where survival is difficult for zooplankton and larval fish. Although numerous studies have examined the effects of extreme reservoir drawdown on water quality, few have examined extreme drawdown on both abiotic and biotic characteristics. A fissure in the dam at Red Willow Reservoir in southwest Nebraska necessitated an extreme drawdown; the water level was lowered more than 6 m during a two-month period, reducing reservoir volume by 76%. During the subsequent low-water period (i.e., post-drawdown), spring sampling (April-June) showed dissolved oxygen concentration was …

Conservation Biology Of The Endangered Swamp Metalmark Butterfly (Calephelis Muticum), Alison Gordon Jan 2016

Conservation Biology Of The Endangered Swamp Metalmark Butterfly (Calephelis Muticum), Alison Gordon

Theses & ETDs

The Swamp Metalmark (Calephelis muticum) is a small North American butterfly (Riodinidae: Lepidoptera). It resides solely in calciferous fens, a wetland found only in the glaciated Midwest. Environmental processes, like succession, coupled with nearby anthropogenic change have fragmented these fens into small, isolated patches. This habitat loss has resulted in small, isolated populations throughout the range. These small populations are much more vulnerable to disease and are less likely to recover after a significant population decline. In this thesis, I evaluated two populations of C. muticum;one at the Riveredge Nature Center (Saukville, WI) and one along Boone Creek Road (Boone …

Arsenic In Drinking Water And Lung Cancer Mortality In The United States: An Analysis Based On Us Counties And 30 Years Of Observation (1950-1979)., Hamid Ferdosi, Elisabeth K Dissen, Nana Ama Afari-Dwamena, Ji Li, Rusan Chen, Manning Feinleib, Steven H Lamm

Epidemiology Faculty Publications

Background. To examine whether the US EPA (2010) lung cancer risk estimate derived from the high arsenic exposures (10-934 µg/L) in southwest Taiwan accurately predicts the US experience from low arsenic exposures (3-59 µg/L). Methods. Analyses have been limited to US counties solely dependent on underground sources for their drinking water supply with median arsenic levels of ≥3 µg/L. Results. Cancer risks (slopes) were found to be indistinguishable from zero for males and females. The addition of arsenic level did not significantly increase the explanatory power of the models. Stratified, or categorical, analysis yielded relative risks that hover about 1.00. …

A New Look At Care In Pregnancy: Simple, Effective Interventions For Neglected Populations, Stephen Hodgins, James M. Tielsch, Kristen Rankin, Amber Robinson, Annie Kearns, Jacquelyn Caglia

Global Health Faculty Publications

Background

Although this is beginning to change, the content of antenatal care has been relatively neglected in safe-motherhood program efforts. This appears in part to be due to an unwarranted belief that interventions over this period have far less impact than those provided around the time of birth. In this par, we review available evidence for 21 interventions potentially deliverable during pregnancy at high coverage to neglected populations in low income countries, with regard to effectiveness in reducing risk of: maternal mortality, newborn mortality, stillbirth, prematurity and intrauterine growth restriction. Selection was restricted to interventions that can be provided by …

Assessing Future Vegetation Trends And Restoration Prospects In The Karst Regions Of Southwest China, Xiaowei Tong, Kelin Wang, Martin Brandt

KIP Articles

To alleviate the severe rocky desertification and improve the ecological conditions in Southwest China, the national and local Chinese governments have implemented a series of Ecological Restoration Projects since the late 1990s. In this context, remote sensing can be a valuable tool for conservation management by monitoring vegetation dynamics, projecting the persistence of vegetation trends and identifying areas of interest for upcoming restoration measures. In this study, we use MODIS satellite time series (2001–2013) and the Hurst exponent to classify the study area (Guizhou and Guangxi Provinces) according to the persistence of future vegetation trends (positive, anti-persistent positive, negative, anti-persistent …

Social Disparities In Exposure To Point-Of-Sale Cigarette Marketing, Mohammad Siahpush, Evi A. Farazi, Jungyoon Kim, Tzeyu L. Michaud, Aaron Yoder, Ghada Soliman, Melissa Tibbits, Minh N. Nguyen, Raees A. Shaikh

Journal Articles: Epidemiology

While most ecological studies have shown that higher levels of point-of-sale (POS) cigarette marketing are associated with larger proportions of residents from lower socioeconomic and minority backgrounds in neighborhoods, there are no studies that examine individual-level social disparities in exposure to POS cigarette marketing among smokers in the United States. Our aim was to examine these disparities in a Midwestern metropolitan area in the United States. We conducted a telephone survey to collect data on 999 smokers. Cigarette marketing was measured by asking respondents three questions about noticing advertisements, promotions, and displays of cigarettes within their respective neighborhoods. The questions …


Characterization Of Mechanisms That Mediate Cancer Metastatic Colonization, Alexander Huan Nguyen Jan 2016

Characterization Of Mechanisms That Mediate Cancer Metastatic Colonization, Alexander Huan Nguyen

Student Theses and Dissertations

Metastatic disease is the major cause of death in all solid tumor cancers. Current therapeutic strategies fail to target metastasis as the genes and mechanisms that regulate this process remain poorly understood. Metastatic colonization is the final step of the metastatic cascade whereby cancer cells form a tumor at a distant site. This final step is the culmination of clonal evolution of cancer populations that results in a highly aggressive population with enhanced metastatic capacity and often presents clinically as numerous inoperable tumor nodules that lead to mortality. Characterization of the mechanisms that govern metastatic colonization at cellular and molecular …


Relationship Between Family Income And Obesity Among African American Adults, Charles Dadzie Boison Jan 2016

Relationship Between Family Income And Obesity Among African American Adults, Charles Dadzie Boison

Walden Dissertations and Doctoral Studies

Obesity is a chronic disease that is caused by a number of factors such as diet, genetics, physical inactivity, and poor dietary habits. This research focused on how income affects obesity among a target population in the African American community in Durham, North Carolina (NC). It has been noted that chronic diseases that are diet-related, for example, obesity, diabetes, hypertension, and high cholesterol, affect African Americans disproportionately, especially those who earn low income. Some studies have also reported that those who make higher income have higher rates of obesity. This inconsistency and gap in the literature prompted research on this …


An Ecological Perspective On Pertussis, Jody Ruth Goard Jan 2016

An Ecological Perspective On Pertussis, Jody Ruth Goard

Walden Dissertations and Doctoral Studies

In 2012, 48,277 cases of pertussis were diagnosed in the United States. Pertussis, otherwise known as whooping cough, is a highly contagious, often debilitating, sometimes deadly, vaccine-preventable disease with an increasing incidence and death rate in the U.S, which may be due to vaccine exemptions. The purpose of this project was to determine if a relationship exists between immunization policies and immunization exemption rates, immunization exemption rates and pertussis rates, and immunization policies and pertussis rates in each state. Bronfenbrenner's bio-ecological framework was used to guide the project. Publically available data from the Centers for Disease Control and Prevention (CDC), …
