Book Description
Prairie mounds are unique soil surface features that will become increasingly scarce as native tallgrass prairies are continually lost. This study aimed to evaluate (i) whether the soil moisture regime (SMR), mound position, and soil depth affect soil volumetric water content (VWC) and (ii) whether the SMR and mound position affect vegetation over time. Soil VWC was measured continuously from April 2017 to June 2018, and vegetation was sampled in June and August 2017 and in May and August 2018. Maximum VWC for selected rainfall events was ~ 2.5 times greater at 10¬†cm in the aquic inter-mound than the udic mound position at 30¬†cm. Soil dry-down rates were four times greater in the udic soil at 10¬†cm than the aquic soil at 30¬†cm. Aboveground plant biomass was numerically largest (8489¬†kg¬†ha,àí1) at the aquic summit in August 2018 and smallest (1280¬†kg¬†ha,àí1) at the aquic inter-mound in May 2018. Results clearly demonstrate the effects that prairie mound topography and differing SMRs have on soil water dynamics and prairie vegetation and suggest that management efforts need to account for mound topography and SMR in order to be most successful.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
In this book, plant biology is considered from the perspective of plants and their surrounding environment, including both biotic and abiotic interactions. The intended audience is undergraduate students in the middle or final phases of their programs of study. Topics are developed to provide a rudimentary understanding of how plant-environment interactions span multiple spatiotemporal scales, and how this rudimentary knowledge can be applied to understand the causes of ecosystem vulnerabilities in the face of global climate change and expansion of natural resource use by human societies. In all chapters connections are made from smaller to larger scales of ecological organization, providing a foundation for understanding plant ecology. Where relevant, environmental threats to ecological systems are identified and future research needs are discussed. As future generations take on the responsibility for managing ecosystem goods and services, one of the most effective resources that can be passed on is accumulated knowledge of how organisms, populations, species, communities and ecosystems function and interact across scales of organization. This book is intended to provide some of that knowledge, and hopefully provide those generations with the ability to avoid some of the catastrophic environmental mistakes that prior generations have made.

Book Description
The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.
