Review Of Grass: In Search Of Human Habitat. By Joe C. Truett. Foreword By Harry W. Greene., Mary Ann Vinton Oct 2011

Review Of Grass: In Search Of Human Habitat. By Joe C. Truett. Foreword By Harry W. Greene., Mary Ann Vinton

Great Plains Research: A Journal of Natural and Social Sciences

Much of the book is devoted to discussing the heavy human dependence on grasslands and whether this relationship can be maintained in company with grassland conservation. Can humans continue to use grasslands for food, fiber, and newer uses like biofuels and carbon banking while still sustaining the ecosystem? Many of us in academic ecology struggle with resolving perceived conflicts between conservation and human grassland use. In many cases, a "win-win" scenario exists in which, for example, the proper use of livestock grazing is perfectly compatible with a healthy grassland ecosystem. In other cases, such as conserving prairie dog populations, tensions …


Future Participation In The Conservation Reserve Program In North Dakota, Lorilie M. Atkinson, Rebecca J. Romsdahl, Michael J. Hill Oct 2011

Future Participation In The Conservation Reserve Program In North Dakota, Lorilie M. Atkinson, Rebecca J. Romsdahl, Michael J. Hill

Great Plains Research: A Journal of Natural and Social Sciences

The purpose of this study was to gauge the impact of agriculture and energy policies on conservation practices through a survey of conservation reserve program (CRP) contract holders in a selected Prairie Pothole Region of North Dakota-Burleigh, Kidder, and Stutsman Counties. The survey results showed that 48% of respondents are considering returning CRP acres to annual crop production once the contract expires. The largest influence on post-CRP land use was the market prices for production of annual crops. Respondents also identified lack of knowledge of conservation programs as a large hurdle to participation. This may indicate a need for improved …

Effects Of Herbicides And Grazing On Floristic Quality Of Native Tallgrass Pastures In Eastern South Dakota And Southwestern Minnesota, Alexander J. Smart, Matthew J. Nelson, Peter J. Bauman, Gary E. Larson Oct 2011

Effects Of Herbicides And Grazing On Floristic Quality Of Native Tallgrass Pastures In Eastern South Dakota And Southwestern Minnesota, Alexander J. Smart, Matthew J. Nelson, Peter J. Bauman, Gary E. Larson

Great Plains Research: A Journal of Natural and Social Sciences

Historic herbicide use and grazing have influenced natural diversity and quality of native pasturelands in the Great Plains. Floristic quality assessments are useful to assist agencies in prioritizing conservation practices to enhance native grasslands. The objective of this study was to determine the effects of past land-use practices on the floristic quality of remnant native pastures in eastern South Dakota and southwestern Minnesota. Floristic quality assessments were conducted on 30 native pastures and categorized by past management practices (herbicide application and grazing intensity). Mean coefficient of conservatism (C) and floristic quality index (FQI) were calculated for each site~Results showed that …


Ecoregional Differences In Late-20th-Century Land-Use And Land-Cover Change In The U.S. Northern Great Plains, Roger F. Auch, Kristi Sayler, Darrell E. Napton, Janis L. Taylor, Mark S. Brooks Oct 2011

Ecoregional Differences In Late-20th-Century Land-Use And Land-Cover Change In The U.S. Northern Great Plains, Roger F. Auch, Kristi Sayler, Darrell E. Napton, Janis L. Taylor, Mark S. Brooks

Great Plains Research: A Journal of Natural and Social Sciences

Land-cover and land-use change usually results from a combination of anthropogenic drivers and biophysical conditions found across multiple scales, ranging from parcel to regional levels. A group of four Level III ecoregions located in the u.s. northern Great Plains is used to demonstrate the similarities and differences in land change during nearly a 30-year period (1973-2000) using results from the U.S. Geological Survey's Land Cover Trends project. There were changes to major suites of land-cover; the transitions between agriculture and grassland/shrubland and the transitions among wetland, water, agriculture, and grassland/shrubland were affected by different factors. Anthropogenic drivers affected the land-use …


Understanding Bioprospecting: Can Indigenous Populations Benefit From The Search For Pharmaceuticals In Areas Of High Biodiversity, Emily Schwindt May 2011

Understanding Bioprospecting: Can Indigenous Populations Benefit From The Search For Pharmaceuticals In Areas Of High Biodiversity, Emily Schwindt

Department of Environmental Studies: Undergraduate Student Theses

Bioprospecting is a controversial issue, and anthropologists and other scientists are quick to take sides. The idea of large corporations pumping money into conservation and development programs, while developing what could be the latest life-saving drug simply sounds too good to be true, and often times is. However, if all parties work together and proceed with caution, these benefits could become more than a fantasy. Looking at case studies from Costa Rica, India, South Africa and Panama this paper attempts to find patterns among successful bioprospecting agreements and note shortcomings and identify risks. This information will be used to suggest …


Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins May 2011

Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins

Department of Environmental Studies: Undergraduate Student Theses

A case study was organized at Saratoga Elementary school in Lincoln, Nebraska to obtain data on what children desire in a garden space. To collect this data a school garden space was constructed and an after school garden club was implemented. Students who participated in the after school garden club partook in the study by drawing their ideal garden. Elements that the subjects drew were identified and categorized into ‘highly desired’ and ‘somewhat desired’.

These elements were then incorporated into a proposed garden design plan for Saratoga. The proposal plan uses Permaculture design methods to emphasize sustainability.


Assessing Anglers Identification Of Common Fish Species Of Nebraska, Jason Reed May 2011

Assessing Anglers Identification Of Common Fish Species Of Nebraska, Jason Reed

Department of Environmental Studies: Undergraduate Student Theses

Creel surveys, also known as angler surveys, entail individual interviews with anglers. The interviews include a variety of questions pertaining to their fishing trip on that particular day. The interviewer asks the angler questions that include, but are not limited to what species they caught that day, the size of the fish, how many hours they spent fishing that day, what bait they were using, etc. If the angler does not know the species caught or misidentifies the species there is the potential for the recorded data to negatively impact management techniques that rely on the creel survey data. One …


Archaeoparasitology Of Chaco Canyon, Rachel Paseka May 2011

Archaeoparasitology Of Chaco Canyon, Rachel Paseka

Department of Environmental Studies: Undergraduate Student Theses

Ancient cultures of the Colorado Plateau have been a focus of archaeoparasitology since its inception, and a vast parasitological history is recorded in coprolites preserved in this arid region. The inhabitants of Chaco Canyon dominated Ancestral Puebloan culture between 1050 and 1120 AD and were responsible for the construction of great towns, road systems, and early agriculture. Analysis of the parasites preserved in fecal remains contributes to an increased knowledge of ancient Chacoan health and culture. Nineteen coprolites from four sites in Chaco Canyon were rehydrated and analyzed microscopically for parasite remains. Rhabditiform and filariform nematode larvae were found from …


Review Of Paradise Found: Nature In America At The Time Of Discovery. By Steve Nicholls, John Herron Apr 2011

Review Of Paradise Found: Nature In America At The Time Of Discovery. By Steve Nicholls, John Herron

Great Plains Research: A Journal of Natural and Social Sciences

Covering 500 years in 500 pages, Paradise Found details the amazing abundance of the natural world that greeted the first European arrivals to North America. Such a perspective is not wholly original; pre-Columbian biodiversity has been a popular topic of investigation for two generations of scholars. But as filmmaker, entomologist, and author Steve Nicholls explains, past catalogs of plenty have, if anything, underestimated the bounty of the precontact physical world. Explaining in full detail the transition from ecological complexity to fragile instability makes the narrative of loss all the more powerful. Paradise Found is short on silver linings. This account …


Review Of The Tallgrass Prairie Center Guide To Prairie Restoration In The Upper Midwest. By Daryl Smith, Dave Williams, Greg Houseal, And Kirk Henderson., Gerry Steinauer Apr 2011

Review Of The Tallgrass Prairie Center Guide To Prairie Restoration In The Upper Midwest. By Daryl Smith, Dave Williams, Greg Houseal, And Kirk Henderson., Gerry Steinauer

Great Plains Research: A Journal of Natural and Social Sciences

Tallgrass prairie restoration in the Upper Midwest is the focus of this guide. Its geographic area of coverage includes the eastern fifth of South Dakota and Nebraska and northeast Kansas, a region some ascribe to the eastern Great Plains. Two types of prairie restoration are dealt with: prairie reconstruction, which the authors define as creating prairie from scratch on sites where prairie plants no longer exist; and prairie remnant restoration, defined as upgrading degraded existing prairies. The book comprises five sections: "Reconstruction Planning," "Implementing Reconstruction," "Prairie Restoration and Management," "Special Cases," and "Native Seed Production." There are 16 chapters, each …


Review Of The River Returns: An Environmental History Of The Bow. By Christopher Armstrong, Matthew Evenden, And H.V. Nelles., Ted Binnema, David Vogt Apr 2011

Review Of The River Returns: An Environmental History Of The Bow. By Christopher Armstrong, Matthew Evenden, And H.V. Nelles., Ted Binnema, David Vogt

Great Plains Research: A Journal of Natural and Social Sciences

This book should be read more as a collection of essays on a wide variety of topics related to the Bow River than as a monograph. Each of its thirteen chapters examines an aspect of the history of human interactions with the river, ranging from ranching, forestry, hydroelectricity, and irrigation to urban sanitation, recreational fishing, flooding, and park building. The Bow River is amenable to a discussion of such diverse themes. Its headwaters are among the glaciers of the Rocky Mountains in Banff National Park, but it also flows through the ranching country of the foothills, the major urban center …


Review Of Barnum Brown: The Man Who Discovered Tyrannosaurus Rex. By Lowell Dingus And Mark A. Norell., Donald M. Henderson Apr 2011

Review Of Barnum Brown: The Man Who Discovered Tyrannosaurus Rex. By Lowell Dingus And Mark A. Norell., Donald M. Henderson

Great Plains Research: A Journal of Natural and Social Sciences

The book itself is well written, and follows Brown's life chronologically from birth to death. Along the way, the narrative delves, sometimes quite deeply, into the people and events, both American and foreign, that would have influenced Brown's life and work at the time. The reams of facts, figures, and dates in the book are meticulously referenced using the extensive archives of the AMNH. Brown was notorious for not keeping field notes, and correspondence to and from the field with his bosses, as well as annual reports, are the sources for most of the details of Brown's life while associated …

Review Of A Dry Oasis: Institutional Adaptation To Climate On The Canadian Plains. Edited By Gregory P. Marchildon., Siân Mooney

Great Plains Research: A Journal of Natural and Social Sciences

A Dry Oasis examines past and potential future climate challenges on the Canadian Plains. The book provides extensive discussion, data, and analysis of challenges related to water supply and management within the South Saskatchewan River Basin (SSRB). Past challenges, experiences, and institutional responses are described and used to frame possible future adaptation pathways under expected future climate change. The book provides an excellent grounding in the historical settlement and development of the SSRB, paying particular attention to the ways that the economy, society, and institutions have adapted in response to climatic variability.


Estimation Of Land Surface Evapotranspiration With A Satellite Remote Sensing Procedure, Ayse Kilic, Ian Ratcliffe, Pariskhit Ranade, Kenneth Hubbard, Ramesh K. Singh, Babuarao Kamble, Jeppe Kjaersgaard Apr 2011

Estimation Of Land Surface Evapotranspiration With A Satellite Remote Sensing Procedure, Ayse Kilic, Ian Ratcliffe, Pariskhit Ranade, Kenneth Hubbard, Ramesh K. Singh, Babuarao Kamble, Jeppe Kjaersgaard

Great Plains Research: A Journal of Natural and Social Sciences

There are various methods available for estimating magnitude and trends of evapotranspiration. Bowen ratio energy balance system and eddy correlation techniques offer powerful alternatives for measuring land surface evapotranspiration. In spite of the elegance, high accuracy, and theoretical attractions of these techniques for measuring evapotranspiration, their practical use over large areas can be limited due to the number of sites needed and the related expense. Application of evapotranspiration mapping from satellite measurements can overcome the limitations. The objective of this study was to utilize the METRICTM (Mapping Evapotranspiration at High Resolution using Internalized Calibration) model in Great Plains environmental …


Review Of The Ecology And Management Of Prairies In The Central United States. By Chris Helzer., David J. Gibson Apr 2011

Review Of The Ecology And Management Of Prairies In The Central United States. By Chris Helzer., David J. Gibson

Great Plains Research: A Journal of Natural and Social Sciences

This relatively short book is an informative and easyto- read account of the author's philosophy and advice on how to manage prairies in the Central U.S., an area corresponding to the eastern portion of the Great Plains where tall- and mixed-grass prairie occurred. With fragmentation and huge losses of this region's natural prairie habitat, there is a growing appreciation for active management of remnants and prairie restoration. This book provides an excellent introduction to this topic.


Review Of The Vanishing Face Of Gaia: A Final Warning, By James Lovelock; Foreword By Martin Rees, Robert F. Diffendal Jr. Apr 2011

Review Of The Vanishing Face Of Gaia: A Final Warning, By James Lovelock; Foreword By Martin Rees, Robert F. Diffendal Jr.

Great Plains Research: A Journal of Natural and Social Sciences

In his latest book, The Vanishing Face of Gaia, James Lovelock writes a clear narrative about the major impacts humans are having on the tightly coupled biotic/ abiotic system we call the Earth and that Lovelock refers to as Gaia in his many scholarly works. He tells us that this coupled system acts in concert to maintain the Earth's environment at an optimal condition for the organisms that live together here, modifying, for example, the atmosphere so that its composition stays at about 21% oxygen and 78% nitrogen (in the tale of Goldilocks and the Three Bears this would …
