Evaluation Of A Waistband For Attaching External Radiotransmitters To Anurans, Luke Alexander Groff, Amber Pitt, Robert Baldwin, Aram J K Calhoun, Cynthia Loftin

Publications

Radiotelemetry provides fine-scale temporal and spatial information about an individual's movements and habitat use; however, its use for monitoring amphibians has been restricted by transmitter mass and lack of suitable attachment techniques. We describe a novel waistband for attaching external radiotransmitters to anurans and evaluate the percentages of resulting abrasions, lacerations, and shed transmitters. We used radiotelemetry to monitor movements and habitat use of wood frogs (Lithobates sylvaticus) in 2006 and 2011–2013 in Maine, USA; American toads (Anaxyrus americanus) in 2012 in North Carolina, USA; and, wood frogs, southern leopard frogs (L. sphenocephalus), and green frogs (L. clamitans) in 2012 …

Modeling Gross Primary Production Of Maize And Soybean Croplands Using Light Quality, Temperature, Water Stress, And Phenology, Anthony L. Nguy-Robertson, Andrew E. Suyker, Xiangming Xiao

School of Natural Resources: Faculty Publications

Vegetation productivity metrics, such as gross primary production (GPP) may be determined from the efficiency with which light is converted into photosynthates, or light use efficiency (ϵ). Therefore, accurate measurements and modeling of ϵ is important for estimating GPP in each ecosystem. Previous studies have quantified the impacts of biophysical parameters on light use efficiency based GPP models. Here we enhance previous models utilizing four scalars for light quality (i.e., cloudiness), temperature, water stress, and phenology for data collected from both maize and soybean crops at three Nebraska AmeriFlux sites between 2001 and 2012 (maize: 26 field-years; soybean: …

Parent-Offspring Resemblance In Colony-Specific Adult Survival Of Cliff Swallows, Charles R. Brown, Erin A. Roche, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Survival is a key component of fitness. Species that occupy discrete breeding colonies with different characteristics are often exposed to varying costs and benefits associated with group size or environmental conditions, and survival is an integrative net measure of these effects. We investigated the extent to which survival probability of adult (≥ 1-year old) cliff swallows (Petrochelidon pyrrhonota) occupying different colonies resembled that of their parental cohort and thus whether the natal colony had long-term effects on individuals. Individuals were cross-fostered between colonies soon after hatching and their presence as breeders monitored at colonies in the western Nebraska …

Ethel Austin Martin Program Publications

Background: Birth cohort studies provide the opportunity to advance understanding of the impact of environmental factors on childhood health and development through prospective collection of environmental samples. Methods: We evaluated the feasibility and informative value of the environmental sample collection methodology in the initial pilot phase of the National Children's Study, a planned U.S. environmental birth cohort study. Environmental samples were collected from January 2009–September 2010 at up to three home visits: pre-pregnancy (n¼306), pregnancy (n¼807), and 6-months postnatal (n¼117). Collections included air for particulate matter r2.5 mm (PM2.5), nitrogen dioxide, ozone, volatile organic compounds (VOCs), and carbonyls; vacuum dust …

Using Beaver Works To Estimate Colony Activity In Boreal Landscapes, Carol A. Johnston, Steve K. Windels

Natural Resource Management Faculty Publications

Beaver ponds and beaver-impounded vegetation are indicators of past or present beaver activity that can be detected from aerial photography. A method to quantitatively relate these beaver works with the density of active beaver colonies could benefit beaver management, particularly in areas lacking beaver population data. We compared historical maps (1961–2006) of beaver works at Voyageurs National Park, Minnesota, USA with concurrent aerial surveys of beaver colonies. We tested 2 landscape-scale models of beaver colony density previously developed for a period of beaver population expansion (1940–1986), but they failed to predict colony density after 1986, a period of declining beaver …

Rock Creek Restoration Macroinvertebrate Monitoring Report, Daniel Bedell

Environmental Science and Management Professional Master's Project Reports

Stream restoration is widely used to rebuild habitat for native fisheries, but it is not well understood how current habitat reconstruction practices affect biological diversity. Citizen Science programs have potential to provide supplemental macroinvertebrate data for effectiveness monitoring of reach-scale restoration projects but variability in training, experience and collection methods can make interpretation difficult. The Clackamas Water Environment Services Watershed Health Education Program (WHEP) is an example of a Citizen Science-based program actively collecting biological data from restored streams. The purpose of this project was to use WHEP student-collected data to detect benthic macroinvertebrate community responses to stream restoration practices. …

An Assessment Of The Hydrologic Connection Between Blacktail Creek And A Riverine Wetland For Nutrients Processing Potential, Jonathan Ball

Graduate Theses & Non-Theses

Silver Bow Creek (Blacktail Creek to Warm Springs Creek) is listed as impaired for nitrates, total nitrogen and total phosphorus in the Montana 2014 draft 303(d) list. Blacktail Creek, a head water to Silver Bow Creek, flows approximately 17 miles before joining Silver Bow Creek in Butte, MT. Previous studies have shown that nutrient concentrations in Blacktail Creek are significantly higher than the Montana Department of Environmental Quality (DEQ) target concentrations. In the literature, constructed (treatment) wetlands have been popularly used as an effective Best Management Practice (BMP) to process nutrients from municipal, industrial, and livestock wastewater. While there has …

Dump It Out! An Enquiry Into Consumers’ Everyday Fashion Discourses Through Handbag, Magnum Man Lok Lam, Elita Yee Nee Lam, Wing-Sun Liu

Faculty of Design & Environment (THEi)

Handbag is an iconic fashion accessory in our material culture. Following the tradition of representational thinking, this article introduces the handbag as an epistemic consumption object through which to investigate consumer experiences, practices and identity construction in relation to everyday lived discourses. The handbag research involves an examination of participants’ personal belongings inside their bags together with phenomenological interviews concerning the associated subjective experiences along with these material objects. We demonstrate how these material possessions become the subject of the research that facilitates multiple conversations between researchers and participants as to introspect, evaluate and interpret the significance of symbolic consumption …

Synthesis Of Palladium And Palladium-Copper Nanostructures As Electrocatalysts, Haibin Wu

Graduate Theses and Dissertations

Pd and its alloys are alternatives of Pt as promising catalysts and electrocatalysts for many reactions. Size controlled synthesis of nanoparticles remains a major research subject, since smaller size particles show better catalytic performance. In this work, we developed a modified chemical wet method to prepare Pd and Pd-Cu nanostructures with uniform small size. Different sizes and shapes of Pd nanostructures were successfully synthesized by using the two reducing agents (i.e., L-ascorbyl-6-palmitate or phenylphosphinic acid). The reducing agents play a role to control the final morphologies and sizes of particles. The use of L-ascorbyl-6-palmitate favors to form irregular branch shapes …

Reducing Nutrient Runoff From Poultry Production Facilities Using Locally-Sourced Iron And Aluminum Byproducts, Sheri Lynn Herron

Graduate Theses and Dissertations

Phosphorus (P) inputs to fresh waters can accelerate the eutrophication process. Agricultural nutrient runoff has been shown to be a contributor of P and nitrogen (N). Broiler production areas were evaluated for their potential to contribute P and N to runoff. Broiler house dust (BHD) samples were analyzed and compared to broiler litter (BL), rainfall simulations were conducted on plots adjacent to broiler house fans to evaluate nutrient enrichment in runoff from deposited dust, and runoff was automatically sampled at two culverts draining the land around broiler houses. Following this, an on-farm byproduct containment and nutrient removal structure was designed …

Modification Of Traffic-Related Respiratory Response By Asthma Control In A Population Of Car Commuters, Maria C. Mirabelli, Rachel Golan, Roby Greenwald, Amit U. Raysoni, Fernando Holguin, Priya Kewada, Andrea Winquist, W Dana Flanders, Jeremy A. Sarnat

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

Background: Effects of traffic-related exposures on respiratory health are well documented, but little information is available about whether asthma control influences individual susceptibility. We analyzed data from the Atlanta Commuter Exposure study to evaluate modification of associations between rush-hour commuting, in- vehicle air pollution, and selected respiratory health outcomes by asthma control status.

Methods: Between 2009 and 2011, 39 adults participated in Atlanta Commuter Exposure, and each conducted two scripted rush-hour highway commutes. In-vehicle particulate components were measured during all commutes. Among adults with asthma, we evaluated asthma control by questionnaire and spirometry. Exhaled nitric oxide, forced expiratory volume in …
