Distribution And Productivity Of Naturalized Alfalfa In Mixed-Grass Prairie, Lan Xu, Arvid Boe, Patricia Johnson, Roger N. Gates, Christopher G. Misar

Natural Resource Management Faculty Publications

Alfalfa (Medicago sativa L.) is an important forage and conservation crop in North America but occurrences of naturalized alfalfa in rangelands are rare. A naturalized population of yellow-flowered alfalfa in mixed-grass prairie on the Grand River National Grassland in South Dakota has potential agricultural value for the region. Despite this value, the distribution pattern of this alfalfa among and within native plant communities in the northern Great Plains is unknown. Field studies were conducted from 2003 through 2006 along topographic positions at two sites where yellow-flowered alfalfa was naturalized to evaluate the relationships of yellow-flowered alfalfa on biomass production, cover, …

Enhancing Rural Economies Through Agroforestry, Gary Bentrup, Dean Current, Christopher Hartley, Marlen Eve, Tricia Kovacs, Kate Mcfarland, Eric Norland, David Smith, Susan Stein, Richard Straight

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Executive Summary

Accelerating the adoption of agroforestry will require a better understanding of the economic opportunities and financial benefits to society, says a recent assessment of United States agroforestry.1 Providing this understanding is critical for agroforestry to reach its full potential, whereby it enhances rural economies and provides ecological services that people need, such as clean drinking water. To assess emerging opportunities, the United States Department of Agriculture (USDA) convened more than 60 people in March 2018 to learn, network, and, above all, generate ideas for raising the economic profile and viability of agroforestry in the United States.

Analysing Habitat Connectivity And Home Ranges Of Bigmouth Buffalo And Channel Catfish Using A Large-Scale Acoustic Receiver Network, Eva C. Enders, Colin Charles, Douglas A. Watkinson, Colin Kovachik, Douglas R. Leroux, Henry Hansen, Mark Pegg

School of Natural Resources: Faculty Publications

The determination if fish movement of potadromous species is impeded in a river system is often difficult, particularly when timing and extent of movements are unknown. Furthermore, evaluating river connectivity poses additional challenges. Here, we used large-scale, long-term fish movement to study and identify anthropogenic barriers to movements in the Lake Winnipeg basin including the Red, Winnipeg, and Assiniboine rivers. In the frame of the project, 80 Bigmouth Buffalo (Ictiobus cyprinellus) and 161 Channel Catfish (Ictalurus punctatus) were tagged with acoustic transmitters. Individual fish were detected with an acoustic telemetry network. Movements were subsequently analyzed using a continuous-time Markov model …

River-Wide Habitat Availability For Fish Habitat Guilds: Implications For In-Stream Flow Protection, Jonathan Spurgeon, Mark A. Pegg, Piotr Parasiewicz, Joe Rogers

School of Natural Resources: Faculty Publications

The variation in river discharge alters habitat heterogeneity with implications for the distribution of fish species with different habitat requirements. Assessments of habitat availability following changes in river discharge are difficult to apply at broad spatial scales and with relevance to multiple species. We used a MesoHABSIM modeling approach to quantify river-wide changes in habitat availability for five fish habitat guilds under three river discharge levels along the Niobrara River, NE, USA.We used a time-series of river discharge (1958–2010) to create uniform continuous under-threshold habitat duration curves that identified habitat conditions that may result in periods of stress for fish …

Seasonal Dynamics Of Lipid Metabolism And Energy Storage In The Brazilian Free-Tailed Bat, Elizabeth J. Rogers, Amie S. Sommers, Liam P. Mcguire

School of Natural Resources: Faculty Publications

As small, flying, mammalian endotherms, insectivorous bats are adapted to operate at high levels of energy expenditure. In response to seasonally variable challenges, we predicted that bats should balance energy budgets by flexibly adjusting aspects of their physiology or behavior in ways that elevate metabolic capacity. We examined variation in energy storage and pathways for oxidative metabolism in Brazilian free-tailed bats (Tadarida brasiliensis) related to estimated costs associated with reproduction and migration. We collected pectoral muscle and liver from female T. brasiliensis at six time points during the summer and fall and measured changes in the activity of four enzymes …

Seamless Lidar Surveys Reveal Rates And Patterns Of Subsidence In The Mississippi River Delta, Celeste E. Woock

LSU New Orleans Theses and Dissertations

Light Detection and Ranging (Lidar) data are used to report the temporal and spatial patterns of subsidence as well as the potential contributors to subsidence within the Barataria and Terrebonne Bays. In recent decades, subsidence in southeast Louisiana has become a topic of substantial and growing concern to the scientific community, the local residents, and all those invested in the region. Lidar data were acquired from the United States Geological Survey (USGS) and the LSU Center for Geoinformatics. The data has been manipulated to map the differenced Lidar, complete an instantaneous slope analysis, and determine the thickness of the Holocene …

Fish Community Response To In-Channel Woody Debris In A Channelized River System, Michael W. Archer, Brenda M. Pracheil, Alexandrea E. Otto, Mark A. Pegg

School of Natural Resources: Faculty Publications

Additions of large wood (LW) have become a go-to technique for recovering altered river ecosystems. However, successful applications of this technique are generally limited to unchannelized rivers and headwater streams. Channelization of rivers, that is, engineering river channels to reduce recruitment and retention of in-channel structure, may, by definition, limit success of this restoration technique. Moreover, sufficient time has passed (a century or more) since initial channelization of many large rivers that portions of the fish community associated with LW may have become extirpated. Thus, the maxim that LW leads to a positive fish community response may not hold true. …

Ecological Interventions To Prevent And Manage Zoonotic Pathogen Spillover, Susanne H. Sokolow, Nicole Nova, Kim M. Pepin, Alison J. Peel, Juliet R.C. Pulliam, Kezia Manlove, Paul C. Cross, Daniel J. Becker, Raina K. Plowright, Hamish Mccallum, Giulio A. De Leo

United States Department of Agriculture Wildlife Services: Staff Publications

Spillover of a pathogen from awildlife reservoir into a human or livestock host requires the pathogen to overcome a hierarchical series of barriers. Interventions aimed at one or more of these barriers may be able to prevent the occurrence of spillover. Here, we demonstrate how interventions that target the ecological context in which spillover occurs (i.e. ecological interventions) can complement conventional approaches like vaccination, treatment, disinfection and chemical control. Accelerating spillover owing to environmental change requires effective, affordable, durable and scalable solutions that fully harness the complex processes involved in cross-species pathogen spillover.

United States Department of Agriculture Wildlife Services: Staff Publications

Understanding the distribution of biodiversity across the Earth is one of the most challenging questions in biology. Much research has been directed at explaining the species latitudinal pattern showing that communities are richer in tropical areas; however, despite decades of research, a general consensus has not yet emerged. In addition, global biodiversity patterns are being rapidly altered by human activities. Here, we aim to describe large‐scale patterns of species richness and diversity in terrestrial vertebrate scavenger (carrion‐consuming) assemblages, which provide key ecosystem functions and services. We used a worldwide dataset comprising 43 sites, where vertebrate scavenger assemblages were identified using …

The Economic Impacts Of Blackbird (Icteridae) Damage To Sunflower In The Usa, Karina Ernst, Julie Elser, George Linz, Hans Kandel, Jason Holderieath, Samantha Degroot, Steven Shwiff, Stephanie Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Blackbird (Icteridae) damage to ripening sunflower (Helianthus annuus L.) has been a persistent economic issue in the USA for the last five decades. To quantify losses, we surveyed blackbird damage from 2001 to 2013 (excluding 2004) to physiologically mature sunflower in eight states: North Dakota, South Dakota, Texas, Nebraska, Minnesota, Colorado, Kansas, and Vermont.

RESULTS:We pooled data gathered during the most recent 5 years (2009 to 2013) of the survey and found losses averaged $US2.5 million and $US11.3 million for confectionery and oilseed hybrids, respectively. Three states, North Dakota, South Dakota, and Nebraska, had sufficient acreage and bird damage …

An Integrated Resource Plan For Public Service Company Of Colorado (Psco), Rawley Loken, Alex Smith

Utilizing Compost For Carbon Sequestration: A Strategy For Climate Goals And Land Use Management, Sarah R. Koplowicz

Master's Projects and Capstones

In recent years, research has been developed for the use of compost combined with managed grazing (and manure) on grasslands (DeLonge et al, 2013) or rangelands, resulting in carbon sequestration from the atmosphere back into soil at a relatively high rate . The Marin Carbon Project (MCP) was established as a collaborative effort to analyze the potential effects of this technique for greenhouse gas mitigation. The MCP established that combining compost applications with managed livestock grazing benefits the soil health and native plant community, while simultaneously enabling carbon sequestration through the mechanisms of plant production and microbial activity. Additional recent …

Facilitating Greenhouse Gas Reduction And Climate Change Adaptation Within The Coastal Zone: A Policy Analysis For The California Coastal Commission, Nicole Young

Master's Theses

California is already experiencing impacts to its coastline due to climate change, and more severe impacts are anticipated if greenhouse gas emissions continue to rise. These climate change impacts are especially strong within the California coastal zone, which falls under the jurisdiction of the California Coastal Commission. The Commission has a history of rigorous environmental protection and is committed to protecting California’s coast through proactive planning and regulation, however they will need to initiate coastal policies with ambitious targets to facilitate effective climate change adaptation and mitigation. This study analyzed existing California climate policies and Coastal Commission policies to identify …

Wildfire Exposure To Critical Habitat Of Endangered And Threatened Species In California, Kristin Butcher

Master's Theses

Researchers, fire ecologists and wildlife managers are concerned about impact to endangered and threatened species and their critical habitat due to the projected increase in future wildfires. Wildfires have been studied in California for the last six decades and have been increasing at an alarming rate since the 1980’s. In this study, I use the 2018 spatial dataset for critical habitat of federally endangered and threatened species located in the state boundaries of California and compare it to a spatial dataset for wildfires that have occurred over the span of 32 years (1984 to 2016). Trends are derived from spatial …

Habitat Selection By American Beaverat Multiple Spatial Scales, Guiming Wang, Lance F. Mcclintic, Jimmy D. Taylor

United States Department of Agriculture Wildlife Services: Staff Publications

Background: Semiaquatic mammals require both aquatic and terrestrial habitats, particularly interfaces between the two habitats. As ecosystem engineers, American beaver (Castor canadensis) consume and fell a great amount of deciduous trees. We tested the prediction that open water and amounts of food resources, including hardwood forests (i.e., deciduous trees as the dominant form of vegetation), herbaceous and woody wetlands, and shrubs, would influence the second-order habitat selection (i.e., placing home ranges on the landscape) by American beaver, whereas the third-order habitat selection of American beaver would be associated with woody wetland and shrub edges. We investigated hierarchical habitat selection by …

Riparian Resilience In The Face Of Interacting Disturbances, Alexa S. Whipple

2019 Symposium

Riparian systems of the dryland western United States provide critical ecosystem functions such as diverse habitat for numerous species, flood attenuation and essential water storage in water-limited environments. These systems have experienced long term disturbance from anthropogenic activities including the grazing of livestock in dryland riparian systems and near extirpation of a keystone riparian species, Castor canadensis (beaver). However, increasing frequency of large-scale wildfires and climate change driven weather is altering the severity and scale of riparian disturbance. Beaver restoration has been gaining use to address long term riparian disturbances, yet little is understood regarding the impact of restored beaver …

Gas Production Kinetics And In Vitro Degradability Of Tannin-Containing Legumes, Alfalfa And Their Mixtures., Sebastian Lagrange, S. Lobón, Juan J. Villalba

Wildland Resources Student Research

The aim of this study was to determine in vitro ruminal degradability and gas production kinetics of sainfoin (Onobrichis viciifolia; SF), birdsfoot trefoil (Lotus corniculatus; BFT), alfalfa (Medicago sativa L.; ALF) and their binary or trinary mixtures using the gas production technique. The proportions in the mixtures represented: (1) those selected by lambs in a free-choice experiment (70:30 and 50:35:15 ratios for binary and trinary combinations, respectively), or (2) equal proportions (50:50 or 33:33:33 ratios for binary or trinary mixtures, respectively). Organic matter digestibility was greater in ALF and BFT than in SF (0.791 and 0.796 vs …

Understanding Ngos And Their Effectiveness Through A Comparative Study Of Their Role In Redd+, Jessica Russo

Political Science Student Scholarship

This thesis explores the following question: what roles do NGOs play and how effective may they be in efforts at global governance? Through a comparative case study analysis of NGOs advocating for Reducing Emissions for Deforestation and forest Degradation (REDD+) and NGOs implementing REDD+ projects, specifically the Surui Forest Carbon Project located in the state of Rondônia, Brazil, I examine whether NGOs are more effective taking on the role as advocates or policy implementers. For this work, I will argue that independent of the multiplicity of roles that NGOs play, their effectiveness is a function of the level of their …

Epidemic Growth Rates And Host Movement Patterns Shape Management Performance For Pathogen Spillover At The Wildlife–Livestock Interface, Kezia R. Manlove, Laura M. Sampson, Benny Borremans, E. Frances Cassirer, Ryan S. Miller, Kim M. Pepin, Thomas E. Besser, Paul C. Cross

United States Department of Agriculture Wildlife Services: Staff Publications

Managing pathogen spillover at the wildlife–livestock interface is a key step towards improving global animal health, food security and wildlife conservation. However, predicting the effectiveness of management actions across host–pathogen systems with different life histories is an on-going challenge since data on intervention effectiveness are expensive to collect and results are system-specific.We developed a simulation model to explore how the efficacies of different management strategies vary according to host movement patterns and epidemic growth rates. The model suggested that fast-growing, fast-moving epidemics like avian influenza were best-managed with actions like biosecurity or containment, which limited and localized overall spillover risk. …

Chapter 1 utilizes a variety of sources from Stephen Hume’s A Stain upon the Sea to Miller’s Living in the Environment, to examine the integral part salmon plays in both freshwater and marine ecosystems, the ecosystem services salmon contribute in wild and farmed settings, and the trends in salmon consumption around the world. Chapter 2 examines the historically relevant role salmon held among indigenous societies and how that role has changed …

Effects Of Forest Management On Densities And Nest Survival Of Breeding Birds In Upland Hardwood Ecosystems, Michael Barnes

Electronic Theses & Dissertations

Over the past 50 years, significant declines in 47% of Neotropical migrant bird species have been documented in North America. Declines are most likely due to the loss and fragmentation of breeding, wintering, and stopover habitat mainly caused by agriculture and urban development. This loss of critical habitat results in population sinks that need to be maintained by immigration from a population source found in continuously forested landscapes. However, in landscapes harvested for timber, forest management practices alter the landscape and as a result, affect breeding bird abundances and nest success. The objective of our study was to determine the …

Rock ptarmigan (Lagopus muta) and willow ptarmigan (L. lagopus) are Arctic birds with a circumpolar distribution but there is limited knowledge about their status and trends across their circumpolar distribution. Here, we compiled information from 90 ptarmigan study sites from 7 Arctic countries, where almost half of the sites are still monitored. Rock ptarmigan showed an overall negative trend on Iceland and Greenland, while Svalbard and Newfoundland had positive trends, and no significant trends in Alaska. For willow ptarmigan, there was a negative trend in mid-Sweden and eastern Russia, while northern Fennoscandia, North America and Newfoundland had no significant trends. …

Policy Insights From Comparing Carbon Pricing Modeling Scenarios, Alexander R. Barron, Marc A.C. Hafstead, Adele C. Morris

Environmental Science and Policy: Faculty Publications

Carbon pricing is an important policy tool for reducing greenhouse gas pollution. The Stanford Energy Modeling Forum exercise 32 convened eleven modeling teams to project emissions, energy, and economic outcomes of an illustrative range of economy-wide carbon price policies. The study compared a coordinated reference scenario involving no new policies with policy scenarios that impose a price on all fossil fuel-related carbon dioxide (CO2) emissions in the U.S. The CO2 price scenarios begin in 2020 at $25/ton or $50/ton and rise each year over inflation at one percent or five percent. The scenarios also vary by the use of the …

Are Firm Emissions Data Likely To Be Accurate Under Carbon-Dioxide Cap & Trade Programs? An Economic Analysis, Kyle Beck

Senior Honors Projects, 2010-2019

Numerous policy makers around the world have implemented carbon dioxide (CO2) cap and trade programs in an effort to combat global climate change. However, under this policy option emitters face incentives to both overstate prior emission levels and then exaggerate emissions reductions induced by regulation. I first build a simple conceptual model which demonstrates these incentives for fraud, and then outline institutional conditions which could plausibly enhance, or else reduce, firm incentives to disseminate erroneous emissions data under this policy option. Next I analyze real world evidence suggesting that duplicitous emissions data, particularly for the pre-regulatory period, is a serious …

School of Natural Resources: Faculty Publications

The inverse relationship between body size and environmental temperature is a widespread ecogeographic pattern. However, the underlying forces that produce this pattern are unclear in many taxa. Expectations are particularly unclear for migratory species, as individuals may escape environmental extremes and reorient themselves along the environmental gradient. In addition, some aspects of body size are largely fixed while others are environmentally flexible and may vary seasonally. Here, we used a long-term dataset that tracked multiple populations of the migratory piping plover Charadrius melodus across their breeding and non-breeding ranges to investigate ecogeographic patterns of phenotypically flexible (body mass) and fixed …
