Fire Effects On Seedling Establishment Success Across Treeline: Implications For Future Tree Migration And Flammability In A Changing Climate, F. S. Chapin Iii, Teresa N. Hollingsworth, Rebecca E. Hewitt
Joint Fire Science Program Research Project Reports
Understanding the complex mechanisms controlling treeline advance or retreat in the arctic and subarctic has important implications for projecting ecosystem response to changes in climate. Changes in landcover due to a treeline biome shift would alter climate feedbacks (carbon storage and energy exchange), ecosystem services such as wildlife and berry habitat, and landscape flammability. Wildfire frequency and extent has increased in the last half-century in the boreal forest and tundra in response to warmer weather and lower precipitation. Invasion of tundra by trees may be facilitated by wildfire disturbance, which exposes new seedbeds, increases nutrient availability immediately post-fire, and creates …

Nebraska Water Center: Faculty Publications
Several groups of microorganisms are capable of producing toxins in aquatic environments. Cyanobacteria are prevalent blue green algae in freshwater systems, and many species produce cyanotoxins which include a variety of chemical irritants, hepatotoxins and neurotoxins. Production and occurrence of potent neurotoxic cyanotoxins β-N-methylamino-L-alanine (BMAA), 2,4-diaminobutyric acid dihydrochloride (DABA), and anatoxin-a are especially critical with environmental implications to public and animal health. Biomagnification, though not well understood in aquatic systems, is potentially relevant to both human and animal health effects. Because little is known regarding their presence in fresh water, we investigated the occurrence and potential for bioaccumulation of cyanotoxins …

Sampling For Effective Ex Situ Plant Conservation, Edward O. Guerrant Jr., Kayri Havens, Pati Vitt
Environmental Science and Management Faculty Publications and Presentations
Sampling a whole flora or any significant subset for ex situ conservation purposes is a complex, long-term proposition. Thus, it is important to consider what constitutes an adequate sample not only for all taxa as a whole but also for each taxon individually as well as how to strategically schedule collection over time. There are five basic sampling questions: from which species to collect, from how many and which populations, from how many and which individuals, how many and what kind of propagules to collect, and, finally, at what point is the desired sample size too great for a population …

Calculating The Solar Energy Of A Flat Plate Collector, Ariane Rosario
Undergraduate Journal of Mathematical Modeling: One + Two
The amount of solar energy that could be obtained by a flat plate solar collector of one square meter dimension is calculated in three different locations: Tampa FL, Fairbanks AL, and Pontianak Indonesia, considering the varying sunset time for each day of the year. The results show that if the collectors are placed near the equator, more total energy could be obtained. In fact, by placing a solar collector in Pontianak, Indonesia 12.42% more solar energy can be obtained than by placing it in Tampa and 96.9% more solar energy than Alaska.

Winter Wind Chill Climatology For The High Plains Region, Holly B. Lussenden, Natalie A. Umphlett, Martha D. Shulski, Daniel Ebert
High Plains Regional Climate Center: Staff Publications
During the winter months in the High Plains region of the United States, wind chill temperatures can reach dangerous levels for humans and animals. Knowing the frequency in which extreme wind chill temperatures occur could help forecasters know when to issue wind chill advisories and also the general public understand just how rare, or common, certain wind chill temperatures are. A climatology spanning a 37-year period was created using data from 57 stations in and around the plains portion of the High Plains region from the Integrated Surface Hourly Database at National Climatic Data Center (NCDC). These climatologies were completed …

The Effects Of Angling Pressure On Northern Pike Size Structure, Ryan Carrow
Journal of Earth and Life Science
A number of conditions within a lake system can affect northern pike (Esox lucius) size structure. Of these conditions, the amount of angling pressure may have the biggest effect on the size structure of northern pike in Minnesota lake systems. In this study, five private and five public lakes were chosen near Bemidji, Minnesota. Each lake was fished for twenty angling hours using live northern hog suckers (Hypentelium nigricans) or golden shiners (Notemigonus crysoleucas). Total length (mm) and weight (kg) were measured for each northern pike caught. The number of fish houses that were …
Achieving ‘Net Zero Energy’ Performance Through Retrofitting Of Residential Buildings In Ireland.,

Achieving ‘Net Zero Energy’ Performance Through Retrofitting Of Residential Buildings In Ireland., M. Alan Costello
Theses
A Net Zero Energy Building (nZEB) is a residential or commercial building that consumes net zero energy over a set period of time, usually taken as one year. In short, for every unit of energy the building consumes over a year, it must generate a unit of energy to maintain an overall net balance. This is achieved by reducing the operational energy usage to a very low level through energy efficient design, and then providing renewable generation technologies on site to cater for the remaining energy demand.
Energy use in all sectors of society is under scrutiny at present, largely …

Introduction To Deliberation, Democracy, And Civic Forums: Improving Equality And Publicity, Chad Raphael, Christopher F. Karpowitz
Communication
Innovative forums that integrate citizen deliberation into policy making are revitalizing democracy in many places around the world. Yet controversy abounds over whether these forums ought to be seen as authentic sources of public opinion and how they should fit with existing political institutions. How can civic forums include less powerful citizens and ensure that their perspectives are heard on equal terms with more privileged citizens, officials, and policy experts? How can these fragile institutions communicate citizens' policy preferences effectively and legitimately to the rest of the political system? Deliberation, Democracy, and Civic Forums proposes creative solutions for improving equality …

A Review Of The Hyporheic Zone, Stream Restoration, And Means To Enhance Denitrification, Leanne Merill, David J. Tonjes
Technology & Society Faculty Publications
The hyporheic zone is the subsurface area below and adjacent to a stream where groundwater mixes with stream water, through vertical, lateral, and longitudinal flows. The hyporheic zone connects the stream to uplands and other terrestrial environments. It is a zone of distinct faunal communities, high biological diversity and ecological complexity, and is the site of chemical processing and transformations of ground- and stream waters. The hyporheic zone is important to the overall ecosystem ecology of the stream, and it can influence stream water chemistry. Flows, reactions, and biota in the hyporheic zone are heterogeneous and patchy, making it difficult …

The Perils Of Ignoring (Or Misunderstanding) Politics And Organizing, David Johns
Political Science Faculty Publications and Presentations
Conservation scientists and advocates were surprised by the U.S. Congress stripping away protection for wolves in the US northern Rocky Mountains. If they had paid attention to earlier political lessons in which court victories had been undermined by determined political organizing they would not have been surprised and could have adopted strategies that would have given them much more leverage with elected officials. Instead conservationists were out-organized and elected officials normally supportive of the U.S. Endangered Species Act responded to anti-wolf groups because they brought more pressure to bear than conservationists. Although political lessons are specific to the system in …

Getting Plant Conservation Right (Or Not): The Case Of The United States, Kayri Havens, Andrea T. Kramer, Edward O. Guerrant Jr.
Environmental Science and Management Faculty Publications and Presentations
Effective plant conservation includes addressing basic needs such as information about species distribution and rarity; research, management, education, and training capacity to mitigate threats facing threatened species; policy and funding to support continued capacity and conservation; and, ultimately, a public that understands and supports the importance of plants and the need for their conservation. Coordination of plant conservation efforts is also needed to ensure that resources and expertise are used in a strategic, efficient, and effective manner.We argue that no country is currently getting plant conservation right; plants are becoming increasingly rare around the world. Plants are often not fully …
