Turning Students Into Problem Solvers, Larkin A. Powell, Andrew J. Tyre, Michael J. Conroy, James T. Peterson, B. Ken Williams Jul 2011

Turning Students Into Problem Solvers, Larkin A. Powell, Andrew J. Tyre, Michael J. Conroy, James T. Peterson, B. Ken Williams

School of Natural Resources: Faculty Publications

In the popular movie Apollo 13, based on the actual NASA mission, three astronauts are stranded in space, their craft’s electrical system broken, their oxygen quickly running out. To help them fix the problem and return home safely, mission controllers summon a group of engineers, dump a pile of equipment onto a desk—the tools available to the astronauts—and tell them to find a solution, or more specifically, “a way to put a square peg in a round hole. Rapidly.” Eventually, the engineers’ plan saves the day, and the astronauts make it home.

State and federal agency biologists generally do …

Cedar Infestation Impacts Avian Communities Along The Niobrara River Valley, Nebraska, January S. Frost, Larkin A. Powell Jul 2011

Cedar Infestation Impacts Avian Communities Along The Niobrara River Valley, Nebraska, January S. Frost, Larkin A. Powell

School of Natural Resources: Faculty Publications

Habitat modification has the potential to cause changes in structure and composition of bird communities. Our goal was to determine the response of Songbird community composition to eastern red cedar (Juniperus virginiana) removal in The Nature Conservancy’s Niobrara Valley Preserve, Nebraska. We used point counts to survey birds in the riparian matrix of grassland and forest habitats. More than 60 species were recorded on surveys during 2004–2005. We also use the program PRESENCE to determine the response of five species to various habitat components, including cedar density: House Wren (Troglodytes aedon), Spotted Towhee (Pipilo maculates …

The Distribution And Life Cycle Of Alliaria Petiolate In Lincoln, Nebraska, Caleb Pharris Jul 2011

The Distribution And Life Cycle Of Alliaria Petiolate In Lincoln, Nebraska, Caleb Pharris

Department of Environmental Studies: Undergraduate Student Theses

Alliaria petiolata (Garlic Mustard) is a biennial alien invasive plant species of the Brassicacea family. It is responsible for displacing native plant species throughout North America and its management has proven to be extremely difficult. Recently several populations of Alliaria petiolata have been discovered in southwestern Lincoln, Nebraska. The spread of Alliaria petiolata is a concern for natural resource managers and the general public. Due to the difficulty of its control, Alliaria petiolata is capable of creating monocultures which diminish the aesthetic value of an ecosystem. While most commonly found in the understory of hardwood forests, it is capable of …


Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger Jul 2011

Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger

Physics Faculty Publications

This paper addresses the issue of how to account for short‐term temporal variability of renewable energy sources and power demand in long‐term climate change mitigation scenarios in energy‐economic models. An approach that captures in a stylized way the major challenges to the integration of variable renewable energy sources into power systems has been developed. As a first application this approach has been introduced to REMIND‐D, a hybrid energy‐economy model of Germany. An approximation of the residual load duration curve is implemented. The approximating function endogenously changes depending on the penetration and mix of variable renewable power. The approach can thus …


Spatial Accuracy Of Climate Networks In Nebraska, Andrea J. Coop Jul 2011

Spatial Accuracy Of Climate Networks In Nebraska, Andrea J. Coop

School of Natural Resources: Dissertations, Theses, and Student Research

Climate data has become increasingly scrutinized for its accuracy because of the need for reliable predictions about climate change. The U.S. has taken great strides to keep up with the demand for accurate climate data. Over the last thirty years, vast improvements to instrumentation, data collection, and station siting have created more accurate data records. This study is to explore the accuracy of existing networks. This study analyzes three climate networks used in Nebraska: the U.S. Historical Climatology Network (HCN), the Automated Weather Data Network (AWDN), and the newest network, the U.S. Climate Reference Network (CRN). Each of these networks …


Late Holocene History Of Dune Activity Along The Elkhorn River In Northeastern Nebraska, Rebecca A. Young Jul 2011

Late Holocene History Of Dune Activity Along The Elkhorn River In Northeastern Nebraska, Rebecca A. Young

School of Natural Resources: Dissertations, Theses, and Student Research

The Nebraska Sand Hills have been an important study area for dune activation and the nature of prehistoric drought events in the Great Plains. However, little has been done to understand the impact of these droughts to smaller dune fields along the eastern margin of the Great Plains. This study focuses on the Stanton dune field which is found about 145 km east of the Sand Hills along the southern edge of the Elkhorn River valley in northeastern Nebraska. With a wetter and slightly cooler climate regime than that of the Nebraska Sand Hills and most other central Great Plains …

Green Jobs And The Ohio Economy: The Workforce Skills And Training Ohio Green Industries Need, Wright State University, Center For Urban And Public Affairs, U.S. Department Of Labor Employment And Training Administration

Economic Development

In spring 2011, a survey was conducted with private employers representing selected sectors within the potential green industry. The following report presents research results about employers and the labor force skills they require to be successful in Ohio’s Green Industry.

As mentioned in earlier parts of this report series, there are many challenges to studying the green economy. The word “potential” in the first sentence of this report is a critical term, because there is no known listing of companies in the green industry. Green industry business association lists exist, but those are membership-based lists and not intended to be …

Navigating the Future of the Colorado River (Martz Summer Conference, June 8-10)

Competition for scarce Colorado River water resources is nothing new, but the conflicts that prompted the seven basin states to negotiate the 1922 Colorado River Compact have grown considerably fiercer and more complex in recent decades. In 2007, responding to the challenges of increasing demand and sustained drought, the seven basin states and a number of other affected interests agreed to a set of interim guidelines for allocating Colorado River water in the event of shortages. This agreement represents an important evolution in the governance of the Colorado River, suggesting that the many interests in the basin can work together …

Detecting Spatiotemporal Changes Of Corn Developmental Stages In The U.S. Corn Belt Using Modis Wdrvi Data, Toshihiro Sakamoto, Brian D. Wardlow, Anatoly A. Gitelson Jun 2011

Detecting Spatiotemporal Changes Of Corn Developmental Stages In The U.S. Corn Belt Using Modis Wdrvi Data, Toshihiro Sakamoto, Brian D. Wardlow, Anatoly A. Gitelson

School of Natural Resources: Faculty Publications

The dates of crop developmental stages are important variables for many applications including assessment of the impact of abnormal weather on crop yield. Time-series 250-m vegetation-index (VI) data acquired from the Moderate Resolution Imaging Spectroradiometer (MODIS) provide valuable information for monitoring the spatiotemporal changes of corn growth across large geographic areas. The goal of this study is to evaluate the performance of a new crop phenology detection method, namely, two-step filtering (TSF), for revealing the spatiotemporal pattern of specific corn developmental stages (early vegetative: V2.5; silking: R1; dent: R5; mature: R6) over an eight-year period (2001–2008) across Iowa, Illinois, and …


An Analysis Of A Management Case: Green Hill Beach Development Of The Rhode Island Coastal Zone, John R. Braddon Jun 2011

An Analysis Of A Management Case: Green Hill Beach Development Of The Rhode Island Coastal Zone, John R. Braddon

Marine Affairs Theses and Major Papers

One of the most valuable and misused assets possessed by the United States is the rich and highly varied coastal zone. The genesis of much of our material wealth and the basis for success of the early colonies has been our national fascination with the sea. As our industry and population have expanded, the coastal zone has been neglected seriously to the detriment of both current and future generations of Americans. Abuse of the coastal zone stems from employing it as a dumping ground, using the rivers flowing into it for effluent disposal and haphazard, poorly planned development. Since the …

Camera Study For Mammalian Carnivore Presence Across Seasons In Montana De Oro State Park, San Luis Obispo County, Ca, Samuel R. Young

Natural Resources Management and Environmental Sciences

Montana de Oro (MDO) is one of the largest state parks in California. Little is known however about its wildlife or their habits. Large predators such as mountain lion (Puma concolor) and black bear (Ursus americanus), and non–native species such as red fox (Vulpes vulpes) and feral pig (Sus scropha) are of management concern because of their potentially dramatic ecological roles. Cameras were deployed at 5 sites along the Coon Creek hiking trail in spring (May 3–June 7), summer (July 15–August 19), and fall (October 10–November 23) sessions with the goal of …


Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster Jun 2011

Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster

The Prairie Naturalist

We conducted an experiment to investigate effects of species, water (W), and nitrogen (N) on competition among little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), and indiangrass (Sorghastrum nutans). All biomass parameters and the root:shoot ratio of little bluestem were reduced by the presence off 1 of 2 other species, and its shoot biomass and total biomass were both increased by addition of N. Root and shoot biomass of sideoats grama were reduced by the presence of indiangrass and its total biomass was reduced by the presence of itself, whereas its shoot biomass was increased by addition of W at …
