Executive Summary

Changing climate and introduced species are placing an increasing number of species at risk of extinction. Increasing extinction risk is increasing calls to protect species by relocating, or translocating, them to locations with more favorable biotic or climatic conditions. Managed relocation, or assisted migration, of species entails risks to both the conservation target organisms being moved as well as the recipient ecosystems into which they are moved.

Recognizing this risk, calls have been made for practitioners interested in considering a managed relocation project to engage in a serious risk assessment prior to advancing a project. We engaged a …

Protocol For Monitoring Fish Communities In Small Streams In The Heartland Inventory And Monitoring Network, Version 2.0, Hope R. Dodd, David G. Peitz, Gareth Rowell, Janice A. Hinsey, David E. Bowles, Lloyd W. Morrison, Michael D. Debacker, Jennifer L. Haack-Gaynor, Jeffrey M. Williams

United States National Park Service: Publications

Executive Summary

Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. …

Morrison, Janice A. Hinsey, J. Tyler Cribbs, Gareth A. Rowell, Michael D. Debecker, Jennifer L. Haack-Gaynor, Jeffrey M. Williams

United States National Park Service: Publications

Executive Summary

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and …

Responses Of Multiple Structural And Functional Indicators Along Three Contrasting Disturbance Gradients, Amelie Truchy, Ryan A. Sponseller, Frauke Ecke, David G. Angeler, Maria Kahlert, Mirco Bundschuh, Richard K. Johnson, Brendan G. Mckie

School of Natural Resources: Faculty Publications

Ecosystem functioning and community structure are recognized as key components of ecosystem integrity, but comprehensive, standardized studies of the responses of both structural and functional indicators to different types of anthropogenic pressures remain rare. Consequently, we lack an empirical basis for (i) identifying when monitoring ecosystem structure alone misses important changes in ecosystem functioning, (ii) recommending sets of structural and functional metrics best suited for detecting ecological change driven by different anthropogenic pressures, and (iii) understanding the cumulative effects of multiple, co-occurring stressors on structure and function. We investigated variation in community structure and ecosystem functioning of stream ecosystems along …

Motivations To Participate In Hunting And Angling: A Comparison Among Preferred Activities And State Of Residence, Matthew P. Hinrichs, Mark P. Vrtiska, Mark Pegg, Christopher J. Chizinski

School of Natural Resources: Faculty Publications

Motivations for hunting and fishing extend beyond harvesting game and include social, psychological, emotional, and physical benefits. We used data from a web-based questionnaire to compare relationships between preferred hunting or fishing activity types, state of residence, and motivations of hunters and anglers across the central United States (U.S.). Exploratory factor analysis yielded four motivation factors: nature, social, food, and challenge. Differences in terms of state were negligible across all motivation factors (η²_p < .01), indicating similarity across states. Nature (η²_p = .01) and social (η²_p < .01) factors were the first and …

A Novel Strategy To Reconstruct Ndvi Time-Series With High Temporal Resolution From Modis Multi-Temporal Composite Products, Linglin Zeng, Brian Wardlow, Shun Hu, Xiang Zhang, Guoqing Zhou, Guozhang Peng, Daxiang Xiang, Rui Wang, Ran Meng, Weixiong Wu

Center for Advanced Land Management Information Technologies: Publications

Vegetation indices (VIs) data derived from satellite imageries play a vital role in land surface vegetation and dynamic monitoring. Due to the excessive noises (e.g., cloud cover, atmospheric contamination) in daily VI data, temporal compositing methods are commonly used to produce composite data to minimize the negative influence of noise over a given compositing time interval. However, VI time series with high temporal resolution were preferred by many applications such as vegetation phenology and land change detections. This study presents a novel strategy named DAVIR-MUTCOP (DAily Vegetation Index Reconstruction based on MUlti-Temporal COmposite Products) method for normalized difference vegetation index …

What Determines The Success And Failure Of Environmental Crowdfunding?, Takahiro Kubo, Diogo Veríssimo, Shinya Uryu, Taro Mieno, Douglas Macmillan

Department of Agricultural Economics: Faculty Publications

Online crowdfunding can help address the perennial financial shortfalls in environmental conservation and management. Although many online crowdfunding campaigns fail to collect any funds due to not achieving their targets, little is known about what drives success. To address this knowledge gap, we applied a mixed-methods approach to data from 473 successful and failed campaigns hosted on the online crowdfunding platform Readyfor. We found that fundraising performance varied by topic, with campaigns on pet animal management outperforming those focussed on landscape management and sustainable use. We also found that marketing strategies associated with online findability and increased reach through social …

Resource allocation within trees is a zero-sum game. Unavoidable trade-offs dictate that allocation to growth-promoting functions curtails other functions, generating a gradient of investment in growth versus survival along which tree species align, known as the interspecific growth–mortality trade-off. This paradigm is widely accepted but not well established. Using demographic data for 1,111 tree species across ten tropical forests, we tested the generality of the growth–mortality trade-off and evaluated its underlying drivers using two species-specific parameters describing resource allocation strategies: tolerance of resource limitation and responsiveness of allocation to resource access. Globally, a canonical growth–mortality trade-off emerged, but the trade-off …

Diversification Of Angiosperms During The Cretaceous Period, Sakia Fields

Department of Environmental Studies: Undergraduate Student Theses

The topic of the Angiosperms relatively sudden appearance and diversification is a topic that has puzzled plenty of biologists and is even referred to as an “abominable mystery” by Charles Darwin. Up to date, many hypotheses have been proposed using various forms of data to form them. The available knowledge used to evaluate this topic has changed over the years, which has created some theme shifts. Some of the best supported of these hypotheses are more recent, but this does not make older articles unworthy of being evaluated, as they still often have relevant information. In the past, their appearance …

How Is Remote Sensing Being Used To Prevent Wildfires Today?, Luke Lauby

Department of Environmental Studies: Undergraduate Student Theses

Wildfires frequencies and severities are on the rise. To properly combat and contain them, artificial intelligence should be utilized. An in-depth literature review was conducted in order to evaluate the current state of artificial intelligence specifically relating to wildfire prevention and suppression efforts. The findings in this research sheds further light on the helpful implications that these technologies (both satellites and UAVs) do, and can have on wildfire suppression. If further adopted in wildfire suppression efforts, artificial intelligence can play a more effective role. Through this, fires can become better prevented, more controllable, and better understood using modern technology.

The Effect Of Agkistrodon Contortrix And Crotalus Horridus Venom Toxicity On Strike Locations With Live Prey, Chase Giese

Department of Environmental Studies: Undergraduate Student Theses

This paper aims to uncover if there is a significant difference in the strike location of snake species that have different values of LD50% venom. It is thought that most snakes strike their prey in the anterior (head) area in order for their venom to work quicker in killing them. Venom toxicity is measured by its LD50% value, which is the amount of venom, in mg/kg, to kill 50% of a test population. The Copperhead has an LD50% value of 10.9 mg/kg, and the Timber Rattlesnake has an LD50% value of 1.64 mg/kg. The hypothesis was that if venom toxicity …

Distribution Of Green Spaces In Omaha, Nebraska, Sofia Gavia

Department of Environmental Studies: Undergraduate Student Theses

The distribution of parks often depends on the races, ethnicity, and socioeconomic class of a community’s households. Parks and green spaces provides community residents recreational opportunities, economic benefits, and improves community public health. The unequal distribution of parks and green spaces in a city is a social issue found across the country. Limited research has been done on the relationship between green spaces and park access and social justice in Omaha, Nebraska. This study discusses whether there is a difference in how parks are distributed in Omaha, NE in terms of social justice and equitable distribution. Research is done using …

Temporal And Spatial Interactions Between Coyotes And Red Foxes Along The Urban–Rural Interface, Adam Mortensen

Department of Environmental Studies: Undergraduate Student Theses

Intraguild competition between predators may cause one predator to alter their temporal activity patterns or occupancy to reduce competition or avoid aggressive encounters. I conducted a temporal activity pattern and occupancy study of coyotes (Canis latrans) and red foxes (Vulpes vulpes) in and around Lincoln, Nebraska using camera traps deployed from September of 2020 to May of 2021. I evaluated the activity patterns of coyotes, red foxes, and humans in urban and rural settings along with the activity patterns of red foxes when sympatric or allopatric with coyotes and determined the coefficient of overlap (Δ) between …

Relationship Of Land Use Categories And Water Quality For Low Order Streams, Jake Mcenaney

Department of Environmental Studies: Undergraduate Student Theses

The relationship of land use categories and water quality was explored in three different streams in the tri-state area of Nebraska, Iowa, and Missouri. These streams included: a fourth order stream, Salt Creek, near Waverly, NE, a third order stream, Maple Creek, near Nickerson, NE, and a sixth order stream, Nodaway River, near Graham, MO. Stream order was to be kept relatively low due to the impact tributary rivers have on a given stream's nitrate concentration. Nearby land use is expected to impact nutrient concentrations to a greater extent for smaller rivers than on larger rivers with more tributaries. First, …
