DOWNLOAD EBOOK →A modified one-dimensional Ripley's K statistic was used to estimate the distances at which clusters of individual species were evident: these distances varied by species and prairie. The relationship between the frequency of each species and soil P, pH, and % OM also varied by species, with few clear trends. There were few species that co-occurred more or less frequently than expected by chance, with no clear trends based on functional groups. Because of the high heterogeneity at this local scale, it does not seem feasible to recommend that reconstructed prairies be seeded to create specific patterns on a small spatial scale. Rather, planting a highly diverse seed mix over a relatively uniform site or part of a site may be the best method to reconstruct highly diverse prairies. My data also provide a reference against which diversity and species composition of reconstructed prairies in southern Iowa could be evaluated.

DOWNLOAD EBOOK →TheTallgrass Restoration Handbook is a hands-on manual that provides a detailed account of what has been learned about the art and science of prairie restoration and the application of that knowledge to restoration projects throughout the world. Chapters provide guidance on all aspects of the restoration process, from conceptualization and planning to execution and monitoring. Appendixes present hard-to-find data on plants and animals of the prairies, seed collection dates, propagation methods, sources of seeds and equipment, and more. Also included is a key to restoration options that provides detailed instructions for specific types of projects and a comprehensive glossary of restoration terms. Written by those whose primary work is actually the making of prairies, The Tallgrass Restoration Handbook explores a myriad of restoration philosophies and techniques and is an essential resource for anyone working to nurture our once vibrant native landscapes back to a state of health.

DOWNLOAD EBOOK →An ideal text for students taking a course in landscape ecology. The book has been written by very well-known practitioners and pioneers in the new field of ecological analysis. Landscape ecology has emerged during the past two decades as a new and exciting level of ecological study. Environmental problems such as global climate change, land use change, habitat fragmentation and loss of biodiversity have required ecologists to expand their traditional spatial and temporal scales and the widespread availability of remote imagery, geographic information systems, and desk top computing has permitted the development of spatially explicit analyses. In this new text book this new field of landscape ecology is given the first fully integrated treatment suitable for the student. Throughout, the theoretical developments, modeling approaches and results, and empirical data are merged together, so as not to introduce barriers to the synthesis of the various approaches that constitute an effective ecological synthesis. The book also emphasizes selected topic areas in which landscape ecology has made the most contributions to our understanding of ecological processes, as well as identifying areas where its contributions have been limited. Each chapter features questions for discussion as well as recommended reading.

DOWNLOAD EBOOK →The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

DOWNLOAD EBOOK →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.
