Available in PDF, EPUB and Kindle. Book excerpt: Throughout the Southwest, complex geology and physiography concomitant with climatic variability contribute to diverse stream hydrogeomorphologies. Many riparian plant species store their seeds in soil seed banks, and germinate in response to moisture pulses, but the climatic controls of this response are poorly understood. To better understand the ecological implications of a changing climate on riparian plant communities, I investigated seed bank responses to seasonal temperature patterns and to stream hydrogeomorphic type. I asked the following questions: Are there distinct suites of warm and cool temperature germinating species associated with Southwestern streams; how do they differ between riparian and terrestrial zones, and between ephemeral and perennial streams? How does alpha diversity of the soil seed bank differ between streams with ephemeral, intermittent, and perennial flow, and between montane and basin streams? Do streams with greater elevational change have higher riparian zone seed bank beta-diversity? Does nestedness or turnover contribute more to within stream beta-diversity? I collected soil samples from the riparian and terrestrial zones of 21 sites, placing them in growth chambers at one of two temperature regimes, and monitoring emergence of seedlings for 12 weeks. Results showed an approximately equal number of warm and cool specialists in both riparian and terrestrials zones; generalists also were abundant, particularly in the riparian zone. The number of temperature specialists and generalists in the riparian zones did not differ significantly between perennial headwater and ephemeral stream types. In montane streams, alpha diversity of the soil seed bank was highest for ephemeral reaches; in basin streams the intermittent and perennial reaches had higher diversity. Spatial turnover was primarily responsible for within stream beta-diversity—reaches had different species assemblages. The large portion of temperature specialists found in riparian seed banks indicates that even with available moisture riparian zone plant community composition will likely be impacted by changing temperatures. However, the presence of so many temperature generalists in the riparian zones suggests that some component of the seed bank is adapted to variable conditions and might offer resilience in a changing climate. Study results confirm the importance of conserving multiple hydrogeomorphic reach types because they support unique species assemblages.

Available in PDF, EPUB and Kindle. Book excerpt: Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.

Download or read book Ecology of Soil Seed Banks written by Mary Allessio Leck and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Soil Seed Banks examines the factors that influence seed bank dynamics and the variety of patterns found among different species. This book presents seed banks in a community context to explore the ecological implications of different patterns, and thus begin the development of a synthesis by comparing various communities. Organized into five parts, this book first examines the general processes that influence inputs or losses from the seed bank, including predation, dormancy/germination mechanisms, and their evolutionary importance. Then, this text examines seed banks in a community context. Only eight vegetation types are included, but the range in diversity of life form, length of growing season, and dominant environmental conditions allow comparisons of seed bank patterns. This book also explores the role of seed banks in vegetation management. This reference material will be a valuable reference material to population and community ecologists and managers. Evolutionary consequences of seed banks should be of interest to population and theoretical biologists.
Download or read book Bioassessment and Management of North American Freshwater Wetlands written by Russell B. Rader and published by John Wiley & Sons. This book was released on 2001-08-07 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first resource of its kind-essential practical guidance on wetlands bioassessment and management Although bioassessment has become a vital tool in the successful management of many aquatic ecosystems, to date there has been no single book that covers the application of bioassessment principles to wetland ecosystems. This contributed volume fills this important gap in the literature, with a multifaceted look at the issues and techniques involved in the successful bioassessment and management of freshwater wetlands. The book is divided into two parts-bioassessment and wildlife management. After a review of general bioassessment principles, Part I discusses the statistical issues related to sampling numerous sites, as well as the application of multivariate procedures and invertebrate functional groups to wetland bioassessment. A series of case studies examines bioassessment results using various organismal groups, followed by several chapters that trace the relationship between bioassessment and wetland restoration. Coverage also explores how to use and sample bacteria, algae, macrophytes, and invertebrates. Part II covers key management topics, including many that are frequently overlooked in other treatments of the subject. Separate chapters discuss how to manage fish, waterbirds, and mosquitoes in wetlands. Other chapters address timber harvest strategies and impact assessment, as well as the biological control of an invasive wetland plant. As wetland managers work to strike a vital balance between resource exploitation and resource protection, this book offers an important repository of practical information to use in meeting this formidable challenge. It will be welcomed by wetland managers and scientists, environmental engineers, ecologists, civil engineers, and others whose work involves wetlands study and management.

Book excerpt: Excerpt from Seed Rain and Seed Bank of Third-and Fifth-Order Streams on the Western Slope of the Cascade Range Little research has been conducted on either the seed bank or the seed rain, seed input, of riparian zones. Possibly, this is because riparian zones frequently are severely disturbed by flooding, and, as with our study sites, they represent narrow interruptions in forest cover. These characteristics, however, do not diminish the eco logical importance of these zones. Riparian zones are distinctive as interfaces be tween two markedly different environments - aquatic and terrestrial (swanson and others As such, riparian zones have sharp gradients of environmental factors and ecological processes. These gradients contribute to the diversity and the spatial and temporal heterogeneity of adjoining terrestrial and aquatic systems (gregory and others With their unique physica characteristics, riparian zones clearly are an important habitat for the study of plant succession.
