Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.
This comprehensive text addresses all of the subjects that a reader who is new to the field will need to know and will be a welcome reference for practitioners at all levels. It includes a history of the discipline, biological and ecological background, principles of the field, basic scientific information on the structure and growth of trees, the complete range of dendrochronology methods, and a full description of each of the relevant subdisciplines.
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.
This book describes the traditional use of wild plants among the Arikara (Sahnish) for food, medicine, craft, and other uses. The Arikara grew corn, hunted and foraged, and traded with other tribes in the northern Great Plains. Their villages were located along the Missouri River in northern South Dakota and North Dakota. Today, many of them live at Fort Berthold Reservation, North Dakota, as part of the MHA (Mandan, Hidatsa, Arikara) Nation. We document the use of 106 species from 31 plant families, based primarily on the work of Melvin Gilmore, who recorded Arikara ethnobotany from 1916 to 1935. Gilmore interviewed elders for their stories and accounts of traditional plant use, collected material goods, and wrote a draft manuscript, but was not able to complete it due to debilitating illness. Fortunately, his field notes, manuscripts, and papers were archived and form the core of the present volume. Gilmore's detailed description is augmented here with historical accounts of the Arikara gleaned from the journals of Great Plains explorers-Lewis and Clark, John Bradbury, Pierre Tabeau, and others. Additional plant uses and nomenclature is based on the field notes of linguist Douglas R. Parks, who carried out detailed documentation of the tribe's language from 1970-2001. Although based on these historical sources, the present volume features updated modern botanical nomenclature, contemporary spelling and interpretation of Arikara plant names, and color photographs and range maps of each species. Kelly Kindscher collected and assembled the historical Gilmore materials; Logan Sutton contributed the Arikara spellings and linguistic analyses; and, Michael and Loren Yellow Bird-Arikara themselves-provided the cultural context. The work serves as an important regional ethnobotany of the Arikara Tribe, one of the most influential on the Northern Plains, and should be of great interest to ethnobotanists, ethnomedical practitioners, historians, and other Indigenous Peoples. More importantly, this book is for the Arikara people of all ages as documentation of, and reconnection to, their cultural heritage.
