Available in PDF, EPUB and Kindle. Book excerpt: This book covers studies on the systematics of plant taxa and will include general vegetational aspects and ecological characteristics of plant life at altitudes above 1000 m. from different parts of the world. This volume also addresses how upcoming climate change scenarios will impact high altitude plant life. It presents case studies from the most important mountainous areas like the Himalayas, Caucasus and South America covering the countries like Malaysia, Sri Lanka, India, Nepal, Pakistan, Kirghizia, Georgia, Russia,Turkey, Indonesia, Malaysia and the Americas. The book will serve as an invaluable resource source undergraduates, graduate students, and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: In 1502, Christopher Columbus named Costa Rica, and while gold and silver never materialized to justify the moniker of rich coast in purely economic terms, scientists and ecotravelers alike have long appreciated its incredible wealth. Wealth in Costa Rica is best measured by its biodiversityhome to a dizzying number of plants and animals, many endemic, it s a country that has long encouraged and welcomed researchers from the world over, and is exemplary in the creation and commitment to indigenous conservation and management programs. Costa Rica is considered to have the best preserved natural resources in Latin America. Approximately nine percent (about 1,000,000 acres) of Costa Rica has been protected in 15 national parks, and a comparable amount of land is protected as wildlife refuges, forest reserves or Indian reservations. This long-awaited synthesis of Costa Rican ecosystems is an authoritative presentation of the paleoecology, biogeography, structure, conservation, and sustainable use of Costa Rica s ecosystems. It systematically covers the entire range of Costa Rica s natural and managed, terrestrial, freshwater and marine ecosystems, including its island systems (Cocos Islands), the Atlantic and Pacific oceans and shores (coasts, coral reefs, mangrove forests), its lowlands (dry, season and wet forests), its highlands (the northern volcanoes and southern Talamanca s), and its estuaries, rivers, lakes, swamps and bogs. The volume s integrated, comprehensive format will be welcomed by tropical and temperate biologists alike, by biogeographers, plant and animal ecologists, marine biologists, conservation biologists, foresters, policy-makers and all scientists, natural history specialists and all with an interest in Costa Rica s ecosystems."

Download or read book Volcanic Ash Soils written by S. Shoji and published by Elsevier. This book was released on 1994-01-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

Book excerpt: The effect of land-use on nutrient cycles of tropical streams on the Osa Peninsula, Costa Rica: a paired catchment approach to investigate current conditions and projected changes. Kelly N. Bringhurst Abstract This study is concerned with potential environmental degradation of soils, rivers and coastal regions of the Osa Peninsula, Costa Rica due to deforestation. A paired, small-catchment approach to the study of environmental pressures on nutrient transfer and aquatic enrichment was used with one catchment that had been cleared for pasture (CN9) and the second primarily undisturbed tropical wet forest (CS 1). Nutrients and related parameters in soils and transferred in normal hydrological discharge were investigated. Soils in the study area are oxisols with concentrations of organic matter, total and plant available P higher in the forested catchment. Indirect measures of suspended sediment by turbidity showed an increase in the deforested catchment stream. Water input via rainfall for the year June 2008-June 2009 was approximately 5000 mm. Stream discharge was approximately 3300 mm year" for each catchment as measured by continuous recorders and evapotranspiration was, on average, 1500 mm year". These data suggested a good resolution of the water balance from independent measurements. The effect of deforestation on stream discharge was a 59% increase in flow during the wet season and an increase in the Q5:Q95 ratio showing that the deforested stream was flashier. Loss of forest canopy and decreased organic matter in the soil resulted in a depletion of available N. The deforested catchment loss of dissolved inorganic nitrogen (DIN) increased 33% over the forested catchment. Soluble reactive phosphorus (SRP) showed a 47% increase in the deforested catchment compared with the forested catchment. The molar N:P ratios were lower than expected and both streams were well below the 0.06 mg L-1 level at which N- limitation has been reported. Effects of nutrient loading have been observed through increased algal growth on equipment surfaces in the deforested catchment stream and increased nutrient yields will likely lead to eutrophication of coastal waters. Key Words - eutrophication, phosphorus, nitrogen, suspended sediment, deforestation, tropical forest.
