Parallel Seasonal Patterns Of Photosynthesis, Fluorescence, And Reflectance Indices In Boreal Trees, Kyle R. Springer, Ran Wang, John A. Gamon
Parallel Seasonal Patterns Of Photosynthesis, Fluorescence, And Reflectance Indices In Boreal Trees, Kyle R. Springer, Ran Wang, John A. Gamon
School of Natural Resources: Faculty Publications
Tree species in the boreal forest cycle between periods of active growth and dormancy alter their photosynthetic processes in response to changing environmental conditions. For deciduous species, these changes are readily visible, while evergreen species have subtler foliar changes during seasonal transitions. In this study, we used remotely sensed optical indices to observe seasonal changes in photosynthetic activity, or photosynthetic phenology, of six boreal tree species. We evaluated the normalized difference vegetation index (NDVI), the photochemical reflectance index (PRI), the chlorophyll/carotenoid index (CCI), and steady-state chlorophyll fluorescence (FS) as a measure of solar-induced fluorescence (SIF), and compared these …
Common Carp Disrupt Ecosystem Structure And Function Through Middle-Out Effects, Mark A. Kaemingk, Jeffrey C. Jolley, Craig P. Paukert, David W. Willis, Kjetil Henderson, Richard S. Holland, Greg A. Wanner, Mark L. Lindvall
Common Carp Disrupt Ecosystem Structure And Function Through Middle-Out Effects, Mark A. Kaemingk, Jeffrey C. Jolley, Craig P. Paukert, David W. Willis, Kjetil Henderson, Richard S. Holland, Greg A. Wanner, Mark L. Lindvall
School of Natural Resources: Faculty Publications
Middle-out effects or a combination of top-down and bottom-up processes create many theoretical and empirical challenges in the realm of trophic ecology. We propose using specific autecology or species trait (i.e. behavioural) information to help explain and understand trophic dynamics that may involve complicated and nonunidirectional trophic interactions. The common carp (Cyprinus carpio) served as our model species for whole-lake observational and experimental studies; four trophic levels were measured to assess common carp-mediated middle-out effects across multiple lakes. We hypothesised that common carp could influence aquatic ecosystems through multiple pathways (i.e. abiotic and biotic foraging, early life feeding, nutrient). Both …
How Do Undergraduate Stem Mentors Reflect Upon Their Mentoring Experiences In An Outreach Program Engaging K-8 Youth?, Kari Nelson, Jaime Sabel, Cory Forbes, Neal Grandgenett, William Tapprich, Christine E. Cutucache
How Do Undergraduate Stem Mentors Reflect Upon Their Mentoring Experiences In An Outreach Program Engaging K-8 Youth?, Kari Nelson, Jaime Sabel, Cory Forbes, Neal Grandgenett, William Tapprich, Christine E. Cutucache
School of Natural Resources: Faculty Publications
Background: Many university students are becoming involved in mentoring programs, yet few studies describe the impact of mentoring on the mentor. Additionally, many studies report that students graduating from college are not prepared to enter the workforce in terms of key career skills and/or content knowledge. Herein, we examine the impact of our program, NE STEM 4U (Nebraska Science, Technology, Engineering and Math for You), in which undergraduate (UG) mentors engage K-8 youth in after-school STEM experiments. The UGs reflected upon their experiences using post-mentoring evaluations, 12- and 24-week interviews, and exit surveys. Many of the questions asked of the …
Population Growth And Mortality Sources Of The Black Bear Population In Northern Georgia, Andrew R. Little, Adam Hammond, James A. Martin, Kristina L. Johannsen, Karl V. Miller
Population Growth And Mortality Sources Of The Black Bear Population In Northern Georgia, Andrew R. Little, Adam Hammond, James A. Martin, Kristina L. Johannsen, Karl V. Miller
School of Natural Resources: Faculty Publications
An understanding of black bear (Ursus americanus) population trends and cause-specific mortality is needed to direct management decisions in northern Georgia given an increasing human population. Therefore, we evaluated black bear population trends and mortality sources across 26 counties and 18 Wildlife Management Areas in northern Georgia from 1979–2014. We collected harvest data from 6,433 individuals during the study period. Using age-at-harvest data, population reconstruction illustrated an increasing trend in the bear population for both males (λ = 1.113) and females (λ = 1.108). Bait station indices reflected a similar increase in the bear population based on increased …
Exploring Elementary Students’ Scientific Knowledge Of Agriculture Using Evidence-Centered Design, Molly Brandt, Cory Forbes, Jenny Keshwani
Exploring Elementary Students’ Scientific Knowledge Of Agriculture Using Evidence-Centered Design, Molly Brandt, Cory Forbes, Jenny Keshwani
School of Natural Resources: Faculty Publications
The public is more disconnected from agriculture than ever. Americans are now two to four generations removed from the farm with a majority of Americans having no direct experience in agriculture. As a result, the public lacks the knowledge and appreciation of the food, fuel, and fiber it demands. The National Agricultural Learning Objectives (NALOs) were recently developed to describe students’ agricultural knowledge but have, as yet, not been used to guide research into students’ agricultural literacy. The purpose of this project is to further understand students’ agricultural literacy through NALO-based assessment of students’ knowledge. This study focused on the …
Unusual Aerobic Performance At High Temperatures In Juvenile Chinook Salmon, Oncorhynchus Tshawytscha, Jamilynn B. Poletto, Dennis E. Cocherell, Sarah E. Baird, Trinh X. Nguyen, Valentina Cabrera-Stagno, Anthony P. Farrell, Nann A. Fangue

School of Natural Resources: Faculty Publications
Understanding how the current warming trends affect fish populations is crucial for effective conservation and management. To help define suitable thermal habitat for juvenile Chinook salmon, the thermal performance of juvenile Chinook salmon acclimated to either 15 or 19°C was tested across a range of environmentally relevant acute temperature changes (from 12 to 26°C). Swim tunnel respirometers were used to measure routine oxygen uptake as a measure of routine metabolic rate (RMR) and oxygen uptake when swimming maximally as a measure of maximal metabolic rate (MMR) at each test temperature. We estimated absolute aerobic scope (AAS = MMR − RMR), …
Nest Site Selection And Nest Survival Of Greater Prairie-Chickens Near A Wind Energy Facility, Jocelyn Olney Harrison, Mary B. Brown, Larkin A. Powell, Walter H. Schacht, Jennifer A. Smith
Nest Site Selection And Nest Survival Of Greater Prairie-Chickens Near A Wind Energy Facility, Jocelyn Olney Harrison, Mary B. Brown, Larkin A. Powell, Walter H. Schacht, Jennifer A. Smith
School of Natural Resources: Faculty Publications
Rapid development of wind energy facilities in the Great Plains of North America has raised concerns regarding their potential negative impact on the nesting ecology of Greater Prairie-Chickens (Tympanuchus cupido pinnatus). We investigated the effects of a pre-existing, 36-turbine wind energy facility on nest site selection and nest survival of Greater Prairie-Chickens in the unfragmented grasslands of the Nebraska Sandhills, USA. In 2013 and 2014, we monitored 91 nests along a 24-km disturbance gradient leading away from the wind energy facility. We found little evidence of an effect of the wind energy facility on Greater Prairie-Chicken nest site …

School of Natural Resources: Faculty Publications
In response to recent educational imperatives in the United States, modeling and systems thinking have been identified as being critical for science learning. In this paper, we investigate models in the classroom from two important perspectives: (1) from the teacher perspective to understand how teachers perceive models and use models in the classroom and (2) from the students perspective to understand how student use model-based reasoning to represent their understanding in a classroom setting. Qualitative data collected from 19 teachers who attended a professional development workshop in the northeastern United States indicate that while teachers see the value in teaching …
Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau
Reframing Communication About Zika And Mosquitoes To Increase Disease Prevention Behavior, Amanda E. Sorensen, Rebecca C. Jordan, Shannon Ladeau
School of Natural Resources: Faculty Publications
Emergence of invasive vector species and the diseases they carry present a clear danger to the public as well as a challenge for scientists and experts to control effectively. Given the urgent need to address this phenomenon, we suggest that desired public action toward these invasive vectors can be motivated through intentional framing in science communication. In this paper, we sought to evaluate the effect of framing about ZIKV (Zika virus) on reported willingness to comply with mosquito prevention action. Post framing intervention, we found a significant increase (N = 26, p < 0.001) in individuals willing to take preventative action against mosquitoes. By methodically investigating best communication practices, this study and others can help practitioners mobilize communities to address large-scale ecological problems. Additionally, the principles outlined here may be transferrable to other communication efforts about ecological issues outside of ZIKV and mosquitoes.

Culturally Induced Range Infilling Of Eastern Redcedar: A Problem In Ecology, An Ecological Problem, Or Both?, Aubrey Streit Krug, Daniel R. Uden, Craig R. Allen, Dirac L. Twidwell Jr
Culturally Induced Range Infilling Of Eastern Redcedar: A Problem In Ecology, An Ecological Problem, Or Both?, Aubrey Streit Krug, Daniel R. Uden, Craig R. Allen, Dirac L. Twidwell Jr
School of Natural Resources: Faculty Publications
The philosopher John Passmore distinguished between (1) “problems in ecology,” or what we might call problems in scientific understanding of ecological change, and (2) “ecological problems,” or what we might call problems faced by societies due to ecological change. The spread of eastern redcedar (Juniperus virginiana) and conversion of the central and southern Great Plains of North America to juniper woodland might be categorized as a problem in ecology, an ecological problem, or both. Here, we integrate and apply two interdisciplinary approaches to problem-solving—social-ecological systems thinking and ecocriticism—to understand the role of human culture in recognizing, driving, and …

School of Natural Resources: Faculty Publications
In the summer of 2012, the central plains of the United States experienced one of its most severe droughts on record. This study examines the meteorological impacts of irrigation during this drought through observations and model simulations using the Community Land Model coupled to the Weather Research and Forecasting (WRF) Model. A simple parameterization of irrigation processes is added into the WRF Model. In addition to keeping soil moisture in irrigated areas at a minimum of 50% of soil moisture hold capacity, this irrigation scheme has the following new features: 1) accurate representation of the spatial distribution of irrigation area …

A Quantitative Framework For Assessing Ecological Resilience, Didier L. Baho, Craig R. Allen, Ahjond Garmestani, Hannah Fried-Petersen, Sophia E. Renes, Lance Gunderson, David G. Angeler
School of Natural Resources: Faculty Publications
Quantitative approaches to measure and assess resilience are needed to bridge gaps between science, policy, and management. In this paper, we suggest a quantitative framework for assessing ecological resilience. Ecological resilience as an emergent ecosystem phenomenon can be decomposed into complementary attributes (scales, adaptive capacity, thresholds, and alternative regimes) that embrace the complexity inherent to ecosystems. Quantifying these attributes simultaneously provides opportunities to move from the assessment of specific resilience within an ecosystem toward a broader measurement of its general resilience. We provide a framework that is based on reiterative testing and recalibration of hypotheses that assess complementary attributes of …

Anthropogenic disturbances can affect species of conservation concern by influencing their behavior. Of special concern is the possibility that noise from anthropogenic structures in grassland habitats, such as wind turbines and roads, may affect the propagation of the low-frequency boom chorus of lekking male Greater Prairie-Chickens (Tympanuchus cupido). We used sound pressure levels from acoustic recordings taken at 10 leks in the Nebraska Sandhills, USA during 2013 and 2014 in a SPreAD-GIS sound propagation model to make spatial projections of the boom chorus under a variety of conditions including landscape composition, conspecific attendance, and weather. We then used sets of …

Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological potential (i.e. potential vegetation), and often fail to account for ongoing changes due to stressors such as land use change and climate change and their effects on plant and animal communities. We use Fisher information, an information theory-based method, on both terrestrial and aquatic animal data (U.S. Breeding Bird Survey and marine zooplankton) to identify ecological boundaries, and compare our results to traditional …

Humans have altered nearly every natural disturbance regime on the planet through climate and land-use change, and in many instances, these processes may have interacting effects. For example, projected shifts in temperature and precipitation will likely influence disturbance regimes already affected by anthropogenic fire suppression or river impoundments. Understanding how disturbance-dependent species respond to complex and interacting environmental changes is important for conservation efforts. Using field-based demographic and movement rates, we conducted a metapopulation viability analysis for piping plovers (Charadrius melodus), a threatened disturbance-dependent species, along the Missouri and Platte rivers in the Great Plains of North America. …

Plant Uptake And Stream Chemistry Set Global Bounds On Nitrogen Gas Emissions From Humid Tropical Forests, E.N.J. Brookshire, S. Gerber, W. Greene, R.A. Jones, Steven A. Thomas
School of Natural Resources: Faculty Publications
Denitrification and hydrologic leaching are the two major pathways by which nitrogen is lost from the terrestrial biosphere. Humid tropical forests are thought to dominate denitrification from unmanaged lands globally, but there is large uncertainty about the range and key drivers of total N gas emissions across the biome. We combined pantropical measures of small watershed stream chemistry with ecosystem modeling to determine total nitrogen gas losses and associated uncertainty across humid tropical forests. Our calculations reveal that denitrification in soils and along hydrologic flowpaths contributes on average >45% of total watershed N losses. However, when denitrification occurs exclusively in …

Ungulate Predation And Ecological Roles Of Wolves And Coyotes In Eastern North America, John F. Benson, Karen M. Loveless, Linda Y. Rutledge, Brent R. Patterson
School of Natural Resources: Faculty Publications
Understanding the ecological roles of species that influence ecosystem processes is a central goal of ecology and conservation biology. Eastern coyotes (Canis latrans) have ascended to the role of apex predator across much of eastern North America since the extirpation of wolves (Canis spp.) and there has been considerable confusion regarding their ability to prey on ungulates and their ecological niche relative to wolves. Eastern wolves (C. lycaon) are thought to have been the historical top predator in eastern deciduous forests and have previously been characterized as deer specialists that are inefficient predators of …

The focus of this study is to investigate the arsenic movement and impacts on the residual concentrations on groundwater pollution load. The Gangetic plain area in the Ballia, Uttar Pradesh is selected as study area, which is also reported to extreme arsenic pollution in soil-water system. A modelling approach is developed to assess the arsenic flux in partially saturated zone using data of soil texture, soil hydraulic properties and stratigraphy. Soil type, slope, and land-use cover is considered for estimating the transient flux at the top boundary from daily precipitation and evapotranspiration data of the study area. Solute transport in …
Hyporheic Flow Possibilities Within Lamprey (Petromyzon Marinus) Redds On The Blackledge River In Marlborough Connecticut, Samuel Fixler
Hyporheic Flow Possibilities Within Lamprey (Petromyzon Marinus) Redds On The Blackledge River In Marlborough Connecticut, Samuel Fixler
Environmental Studies Honors Papers
The fluvial geomorphic process of hyporheic flow provides critical nutrients and dissolved oxygen to macroinvertebrates and eggs within riverbeds through hyporheic exchange. Hyporheic flow may operate at similar scales within sea lamprey (Petromyzon marinus) redds. Limited documentation exists on the hyporheic processes within lamprey redds. This study attempts to measure hyporheic flow using a saline injection syringe and salinity probe to record salinity-time curves. The method was applied to several redds on the Blackledge River, Marlborough, Connecticut. The second aspect of this study examined the hydraulic properties of lamprey redds within a controlled environment in a 0.5 m …
Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker
Analysis Of Bioaccumulation Of Selenium Diets In Brook Trout (Salvelnius Fontinalis), Kyle Aaron Tasker
Theses, Dissertations and Capstones
The brook trout (Salvelinus fontinalis) is facing many challenges throughout the Appalachian region, which are thought to be brought on by effects of climate change and the loss of habitat because of the disturbance from the pursuit of energy sources, namely, the mining of coal in the region. Most of the mining occurs in the central plateau and southern mountain region of West Virginia. The brook trout have historically had an expansive range covering this region and has the potential to inhabit the headwater stream systems that occur very prevalently throughout the Appalachians. In the state of West Virginia, the …

“Fence-Line” Contrast Soundscape Study Of Forested Lands In Allegany State Park And Allegheny National Forest: Is There An Impact Of Oil And Gas Development On An Eastern Forest Soundscape?, Kasey Lynne Osborne
Theses, Dissertations and Capstones
“Natural resources”—an inclusive term indiscriminate of splendor or conservation status – require proper management, be it for forest, oil, water, wildlife, or even soundscapes. The soundscape, or all sounds (biophony, anthrophony, geophony) characterizing an area, is both an ecological monitoring tool and a resource itself—a component of the landscape. As energy demands surge, the oil/gas region of the Appalachian Plateau adjusts to unconventional extraction concurrent with traditional drilling operations. Energy development leaves enduring spatial footprints on the landscape, such as fragmentation from well-pad matrices. Soundscape patterns may not be as readily observed as visual cues, but their analysis can reveal …
