Download or read book Sabkha Ecosystems written by H.-J. Barth and published by Springer Science & Business Media. This book was released on 2002-03-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains 31 contributions presenting the results of recent decades' research on the extensive intertidal and inland saline flats of the Arabian Gulf Region, known colloquially as sabkhat. Only relatively recently acknowledged to be valuable ecosystems with research, development, and conservation value, sabkhat are thoroughly explored in this volume by biologists, geologists, archaeologists, ecologists, botanists, zoologists, and other researchers and scientists from many countries. The volume's 31 contributions are organized into three sections: distribution of sabkhat within the Arabian Peninsula and the adjacent countries (13); sabkha ecology (14); and sabkha land use and development (4). The book includes some fairly low-key b & w photographs, charts, and maps. Annotation copyrighted by Book News, Inc., Portland, OR.

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.

Download or read book The Nile Basin written by Martin Williams and published by Cambridge University Press. This book was released on 2019-01-03 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nile Basin contains a record of human activities spanning the last million years. However, the interactions between prehistoric humans and environmental changes in this area are complex and often poorly understood. This comprehensive book explains in clear, non-technical terms how prehistoric environments can be reconstructed, with examples drawn from every part of the Nile Basin. Adopting a source-to-sink approach, the book integrates events in the Nile headwaters with the record from marine sediment cores in the Nile Delta and offshore. It provides a detailed record of past environmental changes throughout the Nile Basin and concludes with a review of the causes and consequences of plant and animal domestication in this region and of the various prehistoric migrations out of Africa into Eurasia and beyond. A comprehensive overview, this book is ideal for researchers in geomorphology, climatology and archaeology.

The view encompasses more than 2000 kilometers from the river junction in the lower part of the picture to just below the Qena-Luxor bend, at the left upper end. The photograph was taken before the Aswan High Dam basin began to rise. The Red Sea and Saudi Arabia and the Ethiopian Highlands form the background.

A big library could be filled by books on this river devoted to exploration and discovery, human history and hydrology. None has so far been written on the biology of the whole river system.

Download or read book Plant Ecology in the Middle East written by Ahmad Hegazy and published by Oxford University Press. This book was released on 2016-01-14 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This advanced textbook explores the intriguing flora and plant ecology of the Middle East, framed by a changing desert landscape, global climate change, and the arc of human history. This vast region has been largely under-recognized, under-studied, and certainly under-published, due in part to the challenges posed to research by political disputes and human conflict, and a treatise on the subject is now timely. The book integrates Middle Eastern plant geography and its major drivers (geo-tectonics, seed and fruit dispersal, plant functional types, etc.) with the principles of plant ecology. The authors include the many specialized adaptations to desert and dryland ecosystems including succulence, water-conserving photosynthesis, and a remarkable range of other life history strategies. They explore the formation of 'climate relicts', and describe the long history of domestication in the region together with the many reciprocal effects of agriculture on plant ecology. The book concludes by discussing conservation in the region, highlighting five regional biodiversity hotspots where the challenges of desertification, habitat loss, and other threats to plant biodiversity are particularly acute. Plant Ecology in the Middle East is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both undergraduate and graduate students taking courses in plant ecology, evolution, systematics, biodiversity, and conservation, and will also be of interest and use to a professional audience of botanists, conservation biologists, and practitioners working in dryland ecosystems.

A description of the natural history of chameleons is given, along with the fossil record and typical characteristics of each genus. The state of chameleons in the modern world is also depicted, complete with new information on the most serious threats to these remarkable reptiles.
