Download or read book River Biota written by Peter P. Calow and published by John Wiley & Sons. This book was released on 2009-07-08 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with all ecosystems, river systems involve a complex interaction of a rich diversity of micro-organisms, plants and animals with their physical and chemical environment. The river habitat presents unique problems for organisms exposed to unidirectional currents, seasonal variation in flow, and disturbance due to pollution and other human interference. The book starts with a description of the taxa, their adaptations and their ecologies, followed by chapters describing the ecosystem processes in terms of trophic interactions and the key production processes related to photosynthesis and decomposition. A major chapter then considers the principles, practices and problems associated with making reliable observations on river organisms, leading to final chapters investigating how river biota are impacted by human activity and how, in turn, they can be used as indicators of these effects in river-management programmes.

Download or read book Ecology and Conservation of the San Pedro River written by Juliet C. Stromberg and published by University of Arizona Press. This book was released on 2009 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --

Download or read book River Life and the Upspring of Nature written by Naveeda Khan and published by Duke University Press. This book was released on 2022-12-19 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: In River Life and the Upspring of Nature Naveeda Khan examines the relationship between nature and culture through the study of the everyday existence of chauras, the people who live on the chars (sandbars) within the Jamuna River in Bangladesh. Nature is a primary force at play within this existence as chauras live itinerantly and in flux with the ever-changing river flows; where land is here today and gone tomorrow, the quality of life itself is intertwined with this mutability. Given this centrality of nature to chaura life, Khan contends that we must think of nature not simply as the physical landscape and the plants and animals that live within it but as that which exists within the social and at the level of cognition, the unconscious, intuition, memory, embodiment, and symbolization. By showing how the alluvial flood plains configure chaura life, Khan shows how nature can both give rise to and inhabit social, political, and spiritual forms of life.

Download or read book Biodiversity Conservation in Costa Rica written by Gordon W. Frankie and published by Univ of California Press. This book was released on 2004-02-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beautiful tropical dry forest of northwest Costa Rica, with its highly seasonal rainfall and diversely vegetated landscape, is disappearing even more rapidly than Costa Rica's better-known rain forest, primarily because it has been easier to convert to agriculture. This book, based on more than thirty years of study, offers the first comprehensive look at the ecology, biodiversity, and conservation status of this endangered and fragile region. The contributors, from Costa Rica, Britain, Mexico, and the United States, and representing the fields of ecology, environmental education, policy, and the law, examine the major plant and animal groups living in the dry forest and present the first technical evaluation of Costa Rica's conservation efforts. As they assess the status of their area of specialty in the dry forest, the contributors also look beyond this particular region to show how its plants and animals are ecologically and evolutionarily connected to other geographic areas in Costa Rica and Central America. Their chapters cover topics such as watershed and coastal management, plant phenology, pollination, insects, birds, mammals, amphibians, and reptiles. They also consider the socioeconomic, policy, legal, and political aspects of biodiversity conservation, giving the volume a wide-ranging perspective and making a unique contribution to our knowledge of the tropical dry forest. The book concludes with an important synthesis of the contributors' recommendations on future directions, policies, and actions that will better conserve biodiversity in Costa Rica and other neotropical forests as well.
