Spatial Analysis Of Borrow Pits Along The Platte River In South-Central Nebraska, Usa, In 1957 And 2016, Nicole M. Pauley, Mary J. Harner, Emma M. Brinley Buckley, Paul R. Burger, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Central Platte River Valley (CPRV) of Nebraska provides critical habitat for wildlife, while serving agricultural, indus­trial, and other human uses. Mining of sand and gravel from the floodplain of the Platte River has supported construction of roads and other uses, and this extraction has created many borrow-pit ponds, lakes, and other small bodies of standing water (hereafter borrow-pits), further transforming riparian and prairie habitats. The objective of this study was to compare the abundance, size, and distribution of borrow pits before construction of Interstate 80 (1957) and at present (2016) from Lexington to Chapman, Nebraska, a length of river …

Season-Ahead Forecasting Of Water Storage And Irrigation Requirements – An Application To The Southwest Monsoon In India, Arun Ravindranath, Naresh Devineni, Upmanu Lall, Paulina Concha Larrauri

Publications and Research

Water risk management is a ubiquitous challenge faced by stakeholders in the water or agricultural sector. We present a methodological framework for forecasting water storage requirements and present an application of this methodology to risk assessment in India. The application focused on forecasting crop water stress for potatoes grown during the monsoon season in the Satara district of Maharashtra. Pre-season large-scale climate predictors used to forecast water stress were selected based on an exhaustive search method that evaluates for highest ranked probability skill score and lowest root-mean-squared error in a leave-one-out cross-validation mode. Adaptive forecasts were made in the years …

Tracking Drought Perspectives: A Rural Case Study Of Transformations Following An Invisible Hazard, Theresa Jedd, Deborah J. Bathke, Duane Gill, Bimal Paul, Nicole Wall, Tonya K. Bernadt, Jacob Petr, Anthony James Mucia, Milan Wall

School of Natural Resources: Faculty Publications

Rural towns are especially susceptible to the effects of drought because their economies are dependent on natural resources.However, they are also resilient in many ways to natural hazards because they are rich in civic engagement and social capital. Because of the diverse nature of drought’s impacts, understanding its complex dynamics and its effects requires a multidisciplinary approach. To study these dynamics, this research combines appreciative inquiry, the Community Capitals Framework, and a range of climatological monitoring data to assess the 2012–14 Great Plains drought’s effect on McCook, Nebraska. Community coping measures, such as water-use reduction and public health programs, were …

Ecosystem Services And U.S. Stormwater Planning: An Approach For Improving Urban Stormwater Decisions, Todd K. Bendor, Vivek Shandas, Brian Miles, Kenneth Belt, Lydia Olander

Urban Studies and Planning Faculty Publications and Presentations

Green stormwater infrastructure (GI) is gaining traction as a viable complement to traditional “gray” infrastructure in cities across the United States. As cities struggle with decisions to replace deteriorating stormwater infrastructure in the face of looming issues such as population growth and climate change, GI may offer a costeffective, efficient, and sustainable approach. However, decision makers confront challenges when integrating GI within city plans, including uncertainties around GI capacity and maintenance, resistance to collaboration across city governance, increasingly inflexible financing, accounting practices that do not incorporate the multiple values of GI, and difficulties in incorporating ecological infrastructure into stormwater management. …

Motivations, Specializations, Identities, And Constraints Associated With Hunting In Nebraska, Alisha Grams

School of Natural Resources: Dissertations, Theses, and Student Research

This research herein examines the statewide motivations, specializations, identities, and constraints of Nebraska resident hunters. An online survey was conducted in the fall of 2017 asking respondents about their motivations, skills, demographics, and constraints to personal hunting experiences to determine what factors affect hunters. We used factor analysis to examine the effect of motivations, specializations, and constraints to see which factors influence participation. By understanding multiple attributes of our hunters, we gain further insight into participation trends and recreationists needs and expectations. Results suggested that our biggest constraint to overcome is land access, while most people are motivated to hunt …

Wood Waste And Race: The Industrialization Of Biomass Energy Technologies And Environmental Justice, Sarah Mittlefehldt

Journal Articles

In the 1980s, engineers developed new ways to use one of humanity’s oldest fuel sources—wood—to create electrical power. This article uses envirotechnical analysis to examine the development of a wood-burning power plant in Flint, Michigan, and argues that when public officials began working with major energy corporations to build industrial biomass facilities in the 1980s and 1990s, new energy technologies designed to run on renewable fuels became part of an entrenched fossil fuel–based power structure that maintained deep historical inequalities. Like other examples of environmental injustice, the burdens of industrial-scale biomass power systems tended to fall on poor, nonwhite communities. …

Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using > 500,000 time-series observations for 81 species across 86 North American study areas. The effect of climate on local colonization and persistence probabilities varies among eco-regions and depends on local climate, species life-histories, and taxonomic classification. We found that local species richness is most sensitive to changes in water availability during breeding and changes in …

Eddy Covariance Flux Errors Due To Random And Systematic Timing Errors During Data Acquisition, Gerardo Fratini, Simone Sabbatini, Kevin Ediger, Brad Riensche, George Burba, Giacomo Nicolini, Domenico Vitale, Dario Papale

School of Natural Resources: Faculty Publications

Modern eddy covariance (EC) systems collect high-frequency data (10–20 Hz) via digital outputs of instruments. This is an important evolution with respect to the traditional and widely used mixed analog/digital systems, as fully digital systems help overcome the traditional limitations of transmission reliability, data quality, and completeness of the datasets.

However, fully digital acquisition introduces a new problem for guaranteeing data synchronicity when the clocks of the involved devices themselves cannot be synchronized, which is often the case with instruments providing data via serial or Ethernet connectivity in a streaming mode. In this paper, we suggest that, when assembling EC …

Does Environment Filtering Or Seed Limitation Determine Post-Fire Forest Recovery Patterns In Boreal Larch Forests?, Wen H. Cai, Zhihua Liu, Yuan Z. Yang, Jian Yang

Forestry and Natural Resources Faculty Publications

Wildfire is a primary natural disturbance in boreal forests, and post-fire vegetation recovery rate influences carbon, water, and energy exchange between the land and atmosphere in the region. Seed availability and environmental filtering are two important determinants in regulating post-fire vegetation recovery in boreal forests. Quantifying how these determinants change over time is helpful for understanding post-fire forest successional trajectory. Time series of remote sensing data offer considerable potential in monitoring the trajectory of post-fire vegetation recovery dynamics beyond current field surveys about structural attributes, which generally lack a temporal perspective across large burned areas. We used a time series …

Short-Term Low Salinity Mitigates Effects Of Oil And Dispersant On Juvenile Eastern Oysters: A Laboratory Experiment With Implications For Oil Spill Response Activities, Meagan N. Schrandt, Sean Powers, F.Scott Rikard, Wilawan Thongda, Eric Peatman

University Faculty and Staff Publications

Following the Deepwater Horizon oil spill, eastern oyster (Crassostrea virginica) reefs in the northern Gulf of Mexico were exposed to oil and various associated clean-up activities that may have compromised oyster reef health. Included in the exposure was oil, dispersant, and in some locales, atypical salinity regimes. Oil and dispersants can be detrimental to oysters and the effects of salinity depend on the level. In addition to these extrinsic factors, genetic diversity of oyster populations may help the oysters respond to stressors, as demonstrated in other systems. We used a 3×3×2 factorial design to experimentally examine the effects …

Public Perceptions Of Mountain Lake Fisheries Management In National Parks, Ariana M. Chiapella, Max Nielsen-Pincus, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

The legacy of fish stocking in mountain lake ecosystems has left behind a challenge for land managers around the globe. In the US and Canada, historically fishless mountain lakes have been stocked with trout for over a century. These non-native trout have cascading ecosystem effects, and can accumulate atmospherically deposited contaminants. While the negative impacts of stocking in these ecosystems have become increasingly apparent, wilderness fishing has garnered cultural value in the angling community. As a result, public lands managers are left with conflicting priorities. National park managers across the western US are actively trying to reconcile the cultural and …

Potable Water Reuse In Albuquerque, Nm: A Large Scale Community Survey To Understand Public Perceptions And The Impact Of Educational Materials On Acceptance, Lauren Nicole Distler

Architecture and Planning ETDs

In New Mexico and much of the American Southwest, ensuring clean, reliable, and sustainable drinking water supplies is one of the most significant planning challenges. One option to create more diverse and reliable water supplies is potable water reuse. There are two types of potable water reuse: indirect and direct potable reuse (IPR and DPR). Planned potable water reuse has not been widely implemented, largely due to negative public perceptions. This research involves the design and implementation of a large-scale survey administered to a sample of 4,000 water utility customers in Albuquerque, NM, to examine public acceptance of potable water …

Occupancy And Habitat Use By Six Species Of Forest Ungulates On Tiwai Island, Sierra Leone, Kathryn R. Mccollum, Emily Belinfante, April L. Conway, John P. Carroll

School of Natural Resources: Faculty Publications

Forest ungulates in West Africa are common bushmeat species and are subject to habitat degradation through deforestation. Based on historical data, there are possibly 12 species of forest Bovidae and Tragulidae found in eastern Sierra Leone. We used camera trapping to assess occupancy by forest ungulates on and around a small protected area, Tiwai Island, Sierra Leone. We then assessed habitat over two field seasons during 2008–2011 for those species where we had sufficient numbers of detections. We detected 6 of 12 potential species and obtained enough data to further assess the habitat of two species. Species detected included the …

Invasive-Plant-Removal Frequency—Its Impact On Species Spread And Implications For Further Integration Of Forest-Management Practices, Bernabas Wolde, Pankaj Lal

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

For a given invasive plant species and control method, effective invasive plant eradication requires regular monitoring and management. While most previous studies characterize invasive plant species, develop appropriate control methods, or prioritize species for management using aggressiveness and other considerations, few study why some forestland owners are less likely than others to regularly remove invasive plant species. Such information is useful in prioritizing and targeting forestland owners who are at greater risk for invasion, with the stands threatening adjacent forestlands. Towards this end, we surveyed 1800 forestland owners in Virginia and Texas. We use data on forestland owners’ socioeconomics and …

Economics Of Managing Loblolly Pine Plantations For Increased Wildlife Biodiversity, Melissa Griffith

Electronic Theses and Dissertations

The goal of this thesis was to identify the differences between the costs incurred and revenues gained from managing loblolly pine (Pinus taeda) plantations in East Texas for strictly timber production or a combination of timber production and wildlife biodiversity. Management regimes evaluated had varying planting densities, thinning frequency and intensities, prescribed burn intervals, and site indices. Economic analyses used to evaluate management regimes over a range of nonindustrial private landowner (NIPF) alternative rates of return (ARRs) and site indexes were net present worth, land expectation value, and equal annual annuity. These economic analyses demonstrated that altering management …

Management Implications Of Sex-Specific Habitat Use By Nycticeius Humeralis In North-Central Arkansas, Megan Lynn Buckley

Student Theses and Dissertations

The goal of this study was to evaluate evening bat (Nycticeius humeralis) habitat use and provide a proxy strategy to evaluate habitat use by other species. I used the software Maximum Entropy to evaluate habitat suitability models for evening bats using three different modeling strategies; percent variable contribution, the jackknife test, and variable response curves. The predictors included in the models were 10 land use land cover classes, four forest management strategies, slope, and the normalized difference vegetation index (NDVI). The results of this research showed that distance to burned stands and proximity to edge habitat are the most important …

Growth Of Pelagic Age-0 Yellow Perch In Relation To Hatch Dates And Water Temperature In North-Central Minnesota Lakes, Ethan Karppinen

Biology Graduate Theses

Exposure to consistent water warming rates and access to abundant populations of edible sized zooplankton affects growth and increases the probability of survival for newly hatched Yellow Perch Perca flavescens. Seven lakes with varying physical characteristics were selected in north-central Minnesota to study abiotic (water temperature) and biotic (zooplankton community and fish growth) progressions during the spring and early summer (April-June). Mean water temperatures from ice-out to 28 June (11.98-14.62 °C) had significant relationships with mean depth (P < 0.01, R? = 0.85), max depth (P < 0.01, R? = 0.73), and total volume (P < 0.01, R2 = 0.54). Hatch periods ranged from 13 to 19 days in 2015 and 13 to 25 days in 2016. Cumulative degree-days (CDD) were used to predict Yellow Perch hatch periods and explain growth. CDD predicted 21-81% of hatch periods in 2015 and 11-50% in 2016. Mean predicted total lengths at 28 June were 19.65-30.41 mm in 2015 and 20.88-28.54 mm in 2016. There was a significant relationship between CDD and predicted total length (R? = 0.62, P < 0.01) to explain differences in Yellow Perch total length while inhabiting the pelagic zone. Observed gape measurements were highly correlated with predicted gapes from the Schael formula (R? = 0.89, P < 0.01) that was used to assess the availability of edible sized zooplankton for age-0 Yellow Perch in each lake. No predator-prey mismatches were found and earlier hatch dates produced age-0 Yellow Perch with greater predicted total lengths in late June on the majority of lakes. This suggests that earlier hatched Yellow perch have an advantage over later hatched Yellow Perch in attaining greater lengths by late June. Our study provides information on a variety of physical and biological progressions in lakes, which may be used for fisheries management practices in the future.

Quantifying The Environmental Performance Of A Stream Habitat Improvement Project, Cody Morse

Master's Theses

River restoration projects are being installed worldwide to rehabilitate degraded river habitat. Many of these projects focus on stream habitat improvement (SHI), and an estimated 60%of the 37,000 projects listed in the National River Restoration Science Synthesis Program focus on SHI for salmon and trout species. These projects frequently lack a sufficient monitoring program or account for the environmental costs associated with SHI. The present study used life cycle assessment (LCA) techniques and topographic effectiveness monitoring to quantify environmental costs on the basis of geomorphic change. This methodology was a novel approach to assessing the cost-benefit relationship of SHI. To …

Boundary Spanners And Trust Development Between Stakeholders In Integrated Water Resource Management: A Mixed Methods Study, Jodi L. Delozier

School of Natural Resources: Dissertations, Theses, and Student Research

Natural resource issues are inherently complex, even more so are those that involve the management of water. Because watersheds tend to cross multiple jurisdictional and geographical boundaries, a diverse set of stakeholders are needed to develop appropriate and sustainable management policy. This research sheds light on the importance of boundary spanners assisting in the development of trust between stakeholders in integrated water resource management (IWRM). Previous literature has explored the advantages to boundary spanning leadership in business practice, emergency management, university and community management as well as fish and wildlife management, but has failed to address the area of integrated …

Distribution And Habitat Association Of The Northern Long-Eared Bat, Zachary A. Warren

School of Natural Resources: Dissertations, Theses, and Student Research

Because of white-nose syndrome, the northern long-eared bat (Myotis septentrionalis) is experiencing rapid population declines across the majority of its range. This decline has prompted increased regulatory protection and thus an increased need for effective habitat management strategies. Insight into the species habitat associations, however, is a prior necessity to ensure management practices are biologically relevant. Understanding these relationships requires a holistic approach that addresses the multiple ways in which the species is interacting with its environment. The objective of my thesis was to address these relationships following a multi-scale approach that assessed the factors associated with roost …

A Comparison Of Vnir And Mir Spectroscopy For Predicting Various Soil Properties, Joshua R. Gates

School of Natural Resources: Dissertations, Theses, and Student Research

Soil plays an important role in our daily lives, namely producing food, cleaning water and storing carbon. The ability to rapidly and cost-effectively quantify the various components of soils can help us understand and better manage this important resource. This study aims to compare the ability of visible near-infrared (VNIR) spectroscopy and mid-infrared (MIR) spectroscopy to quickly and accurately predict various important soil properties (electrical conductivity, soil pH, cation exchange capacity, exchangeable cations, phosphorus, carbon, beta-glucosidase enzyme activity and nitrogen). Prediction models were developed using partial least squares regression (PLSR) techniques. Three different calibration sampling methods were tested along with …

Cosmic Ray Neutrons Provide An Innovative Technique For Estimating Intermediate Scale Soil Moisture, Thigesh Vather, Colin Everson, Michael Mengistu, Trenton E. Franz

School of Natural Resources: Faculty Publications

Soil moisture is an important hydrological parameter, which is essential for a variety of applications, thereby extending to numerous disciplines. Currently, there are three methods of estimating soil moisture: ground-based (in-situ) measurements; remote sensing based methods and land surface models. In recent years, the cosmic ray probe (CRP), which is an in-situ technique, has been implemented in several countries across the globe. The CRP provides area-averaged soil moisture at an intermediate scale and thus bridges the gap between in-situ point measurements and global satellite-based soil moisture estimates. The aim of this study was to test the suitability of the CRP …
