Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, 2018 University of Nebraska-Lincoln
Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, Edward J. Raynor, Larkin Powell, Walter H. Schacht
Papers in Natural Resources
Better understanding animal ecology in terms of thermal habitat use has become a focus of ecological studies, in large part due to the predicted temperature increases associated with global climate change. To further our knowledge on how ground-nesting endotherms respond to thermal landscapes, we examined the thermal ecology of Sharp-tailed Grouse (Tympanuchus phasianellus) during the nesting period. We measured site-specific iButton temperatures (TiB) and vegetation characteristics at nest sites, nearby random sites, and landscape sites to assess thermal patterns at scales relevant to nesting birds. We asked if microhabitat vegetation characteristics at nest sites matched the characteristics that directed macrohabitat ...
Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, 2018 Utah State University
Community-Level Plant–Soil Feedbacks Explain Landscape Distribution Of Native And Non-Native Plants, Andrew Kulmatiski
Wildland Resources Faculty Publications
Plant–soil feedbacks (PSFs) have gained attention for their potential role in explaining plant growth and invasion. While promising, most PSF research has measured plant monoculture growth on different soils in short-term, greenhouse experiments. Here, five soil types were conditioned by growing one native species, three non-native species, or a mixed plant community in different plots in a common-garden experiment. After 4 years, plants were removed and one native and one non-native plant community were planted into replicate plots of each soil type. After three additional years, the percentage cover of each of the three target species in each community ...
Identifying Riparian Zones Best Suited To Installation Of Saturated Buffers: A Preliminary Multi-Watershed Assessment, 2018 United States Department of Agriculture
Identifying Riparian Zones Best Suited To Installation Of Saturated Buffers: A Preliminary Multi-Watershed Assessment, M. D. Tomer, D. B. Jaynes, S. A. Porter, D. E. James, T. M. Isenhart
Thomas M. Isenhart
Saturated riparian buffers are a new type of conservation practice that divert subsurface tile drainage water from direct discharge to surface water into distribution pipes that discharge the tile water into riparian soils. This enables natural processes of biological uptake and denitrification to decrease nutrient loads that are being lost from croplands via tile drains, reducing water quality impacts from agriculture at relatively little cost. This chapter suggests and evaluates draft criteria that identify riparian zones within a watershed that are suited to installation of saturated buffers. Soils criteria, evaluated using soil survey information, include subsurface accumulations of soil organic ...
Phosphorus Source--Sink Relationships Of Stream Sediments In The Rathbun Lake Watershed In Southern Iowa, Usa, 2018 Iowa State University
Phosphorus Source--Sink Relationships Of Stream Sediments In The Rathbun Lake Watershed In Southern Iowa, Usa, Najphak Hongthanat, John L. Kovar, Michael L. Thompson, James R. Russell, Thomas M. Isenhart
Thomas M. Isenhart
The surface waters of Rathbun Lake watershed in southern Iowa are impacted by agricultural sources of sediments and nutrients, including phosphorus (P). Because stream sediments often play an important role in regulating P concentrations in stream water, we investigated sediment-water column P relationships in four creeks within the watershed and then evaluated the relationship between sediment properties and indicators of the risk of P loss. Based on Mehlich-3-extractable P (17 to 68 mg kg -1) and degree of P saturation (2 to 12 %), stream bank and bed sediments at the four sites were unlikely to serve as major sources of ...

Development And Validation Of A House Finch Interleukin-1Β (Hfil-1Β) Elisa System, Sungwon Kim, Myeongseon Park, Ariel E. Leon, James S. Adelman, Dana M. Hawley, Rami A. Dalloul
James S. Adelman
A unique clade of the bacterium Mycoplasma gallisepticum (MG), which causes chronic respiratory disease in poultry, has resulted in annual epidemics of conjunctivitis in North American house finches since the 1990s. Currently, few immunological tools have been validated for this songbird species. Interleukin-1β (IL-1β) is a prototypic multifunctional cytokine and can affect almost every cell type during Mycoplasma infection. The overall goal of this study was to develop and validate a direct ELISA assay for house finch IL-1β (HfIL-1β) using a cross-reactive chicken antibody.
A direct ELISA approach was used to develop this system using two different coating ...
Application Of Genetics And Genomics To Wildlife Epidemiology, 2018 Iowa State University
Application Of Genetics And Genomics To Wildlife Epidemiology, Julie A. Blanchong, Stacie J. Robinson, Michael D. Samuel, Jeffrey T. Foster
Julie A. Blanchong
Wildlife diseases can have significant impacts on wildlife conservation and management. Many of the pathogens that affect wildlife also have important implications for domestic animal and human health. However, management interventions to prevent or control wildlife disease are hampered by uncertainties about the complex interactions between pathogens and free-ranging wildlife. We often lack crucial knowledge about host ecology, pathogen characteristics, and host–pathogen dynamics. The purpose of this review is to familiarize wildlife biologists and managers with the application of genetic and genomic methodologies for investigating pathogen and host biology to better understand and manage wildlife diseases. The genesis of ...

Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder
Engagement & Service-Learning Summit: Reciprocal & Sustainable Partnerships
The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its ...

Agricultural and Biosystems Engineering Publications
Nutrients in drainage waters from the Upper Mississippi River Basin states have been a well-documented contributor to the Gulf of Mexico hypoxic zone for decades, and in response, twelve states have developed strategies to address this issue, with Iowa, Minnesota, and Illinois performing rigorous science assessments which estimated nitrogen and phosphorus reduction effectiveness for numerous agricultural non-point source conservation practices. The practices identified in these strategies were compared to identify areas of consensus and discord on nutrient load reduction potentials. Additionally, each practice was assessed for (1) the suitability to stack or be layered with other practices (stackability), (2) the ...
Using Unmanned Aerial Systems For Deriving Forest Stand Characteristics In Mixed Hardwoods Of West Virginia, 2018 West Virginia University
Using Unmanned Aerial Systems For Deriving Forest Stand Characteristics In Mixed Hardwoods Of West Virginia, Henry Liebermann, Jamie Schuler, Michael P. Strager, Angela K. Hentz, Aaron Maxwell
Journal of Geospatial Applications in Natural Resources
Forest inventory information is a principle driver for forest management decisions. Information gathered through these inventories provides a summary of the condition of forested stands. The method by which remote sensing aids land managers is changing rapidly. Imagery produced from unmanned aerial systems (UAS) offer high temporal and spatial resolutions to small-scale forest management. UAS imagery is less expensive and easier to coordinate to meet project needs compared to traditional manned aerial imagery. This study focused on producing an efficient and approachable work flow for producing forest stand board volume estimates from UAS imagery in mixed hardwood stands of West ...

Environmental Science and Management Faculty Publications and Presentations
We provide the wildland urban interface (WUI) map of the autonomous community of Catalonia (Northeastern Spain). The map encompasses an area of some 3.21 million ha and is presented as a 150-m resolution raster dataset. Individual housing location, structure density and vegetation cover data were used to spatially assess in detail the interface, intermix and dispersed rural WUI communities with a geographical information system. Most WUI areas concentrate in the coastal belt where suburban sprawl has occurred nearby or within unmanaged forests. This geospatial information data provides an approximation of residential housing potential for loss given a wildfire, and ...
Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark
Scripps Senior Theses
After sixty-two years of U.S. military testing, the small Puerto Rican island of Vieques and its residents continue to fight against ongoing environmental and social effects of U.S. hegemony. Starting with the arrival of the Spanish, then with U.S. occupation and use of Vieques as a military stopover, Viequense residents are used to U.S. governmental presence on their land. Despite the military’s removal from Vieques in 2003, many local residents have a fundamental lack of trust for the U.S. government. Because of this lack of trust and transparency with U.S. governmental actions in ...

Effects Of Subsurface Drainage Systems On Water And Nitrogen Footprints Simulated With Rzwqm2, 2018 Iowa State University
Effects Of Subsurface Drainage Systems On Water And Nitrogen Footprints Simulated With Rzwqm2, Kristina Craft, Matthew J. Helmers, Robert W. Malone, Carl H. Pederson, Linda R. Schott
Agricultural and Biosystems Engineering Publications
Developing drainage water management (DWM) systems in the Midwest to reduce nitrogen (N) transport to the northern Gulf of Mexico hypoxic zone requires understanding of the long-term performance of these systems. Few studies have evaluated long-term impacts of DWM, and the simulation of controlled drainage (CD) with the Root Zone Water Quality Model (RZWQM) is limited, while shallow drainage (SD) has not been examined. We tested RZWQM using nine years (2007-2015) of field data from southeast Iowa for CD, SD, conventional drainage (DD), and undrained (ND) systems and simulated the long-term (1971-2015) impacts. RZWQM accurately simulated N loss in subsurface ...

Effect Of Biomass Inlet Concentration On Mixing In A Double Screw Pyrolyzer, 2017 Iowa State University
Effect Of Biomass Inlet Concentration On Mixing In A Double Screw Pyrolyzer, Breanna L. Marmur, Theodore J. Heindel
Theodore J. Heindel
The renewable energy industry relies on double screw pyrolyzers to convert cellulosic biomass into bio-oil. Bio-oil can then be converted into synthetic gasoline, diesel, and other transportation fuels, or can be converted into biobased chemicals for a wide range of applications. One of the processes by which bio-oil is produced in industry today is through fast pyrolysis, the fast thermal decomposition of organic material in the absence of oxygen. One type of pyrolyzer, a double screw pyrolyzer, features two intermeshing screws encased in a reactor which mechanically conveys and mixes the biomass and heat carrier media. The mixing effectiveness of ...
The Application And Usefulness Of Economic Analyses For Water Quality Management In Coastal Areas, 2017 US Environmental Protection Agency
The Application And Usefulness Of Economic Analyses For Water Quality Management In Coastal Areas, Sheri L. Jewhurst, Kate K. Mulvaney, Marisa J. Mazzotta
Journal of Ocean and Coastal Economics
Economic studies are increasingly sought as tools to contribute to water quality management in estuaries and coastal communities, yet little is known about how the results from existing studies have been received and utilized by the organizations who solicited them. We interviewed managers from eight organizations who solicited economic studies over the past 15 years to understand how useful the studies were to their organizations and what economic research would be most helpful for their management needs. In terms of utility for coastal managers, there are a number of limitations in the studies. These include lack of site-specific data, the ...
Land Use Change And Policy In Iowa’S Loess Hills, 2017 Iowa State University
Land Use Change And Policy In Iowa’S Loess Hills, Gaurav Arora, Peter T. Wolter, David A. Hennessy, Hongli Feng
Land use changes have important implications on ecosystems and society. Detailed identification of the nature of land use changes in any local region is critical for policy design. In this paper, we quantify land use change in Iowa’s Loess Hills ecoregion, which contains much of the state’s remaining prairie grasslands. We employ two distinct panel datasets, the National Resource Inventory data and multi-year Cropland Data Layers, that allow us to characterize spatially-explicit land use change in the region over the period 1982-2010. We analyze land use trends, land use transitions and crop rotations within the ecoregion, and contrast ...
