Available in PDF, EPUB and Kindle. Book excerpt: INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.

Download or read book Phenology: An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2013-07-30 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology refers to recurring plant and animal life cycle stages, such as leafing and flowering, maturation of agricultural plants, emergence of insects, and migration of birds. It is also the study of these recurring events, especially their timing and relationships with weather and climate. Phenological phenomena all give a ready measure of the environment as viewed by the associated organism, and are thus ideal indicators of the impact of local and global changes in weather and climate on the earth’s biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing, and other areas. Like its predecessor, this second edition of Phenology is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students, and interested members of the public. With updated and new contributions from over fifty phenological experts, covering data collection, current research, methods, and applications, it demonstrates the accomplishments, progress over the last decade, and future potential of phenology as an integrative environmental science.

Available in PDF, EPUB and Kindle. Book excerpt: This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book excerpt: El Autana is a sandstone tepuy or butte about 400 miles south of Caracas in the Amazon Territory of Venezuela. We climbed the left hand ridge in the photograph in three days in 1974. A cathedral sized cave pierces the mountain from side to side, so that light shines through about 400 ft from the top. Like all good jungle mountains, this too has its indian legend. At dusk, when the sun shines through the cave that pierces the mountain from one side to side, the Piaroa indians call the cave the 'Eye of the Gods'. Stephen Platt, David Nott, Wilmer Perez la Riva and Carlos Reyes climbed the North Ridge in its entirety and then descended to the caves were we spent three nights, exploring the galleries and traversing around the mountain along the horizontal fault line at the height of the cave. On the third day we completed the ridge to the summit. Night caught us abseiling down the last overhanging 300ft wall and we stumbled back to base camp by the meagre light of our only pocket torch.

Download or read book Psammic Peinobiomes written by Joseph Alfred Zinck and published by Springer Nature. This book was released on 2023-09-30 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book represents a multidisciplinary approach to understanding soil–landscape–vegetation relationships and, specifically, the ecophysiology of plant communities developing on sandy soils of very low fertility that are subject to seasonal flooding. It provides an overview of the white sand ecosystems within the Amazon basin, and focuses on the forest and herbaceous (meadows) vegetation growing on the dystrophic sandy soils of the upper Negro and Orinoco river basins. Several chapters describe physiographic aspects of the study area using integrated remote sensing and in situ sampling. By doing so they attain a comprehensive description of the origin and evolution of soils and landscapes, an advanced classification of soils, and a mapping of the geographic distribution of psammophilous vegetation. This volume also provides a phytosociological classification of extensive forested areas, and a detailed description of the structure and diversity of little-known herbaceous formations.It targets professionals in the fields of ecology, ecophysiology, geomorphology, soils, vegetation, and the environmental sciences. The information it offers may be of significant use to researchers, protected area planners, and environmental policy makers.

Download or read book Ecological Sustainability for Non-timber Forest Products written by Charlie M. Shackleton and published by Routledge. This book was released on 2015-03-24 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing knowledge about and appreciation of the importance of Non-timber Forest Products (NTFPs) to rural livelihoods in developing countries, and to a lesser extent, developed countries. However, there is also an assumption on the part of policy-makers that any harvesting of wild animal or plant products from the forests and other natural and modified ecosystems must be detrimental to the long-term viability of target populations and species. This book challenges this idea and shows that while examples of such negative impacts certainly exist, there are also many examples of sustainable harvesting systems for NTFPs. The chapters review and present coherent and scientifically sound information and case studies on the ecologically sustainable use of NTFPs. They also outline a general interdisciplinary approach for assessing the sustainability of NTFP harvesting systems at different scales. A wide range of case studies is included from Africa, Asia and South America, using plant and animal products for food, crafts, textiles, medicines and cosmetics.
