Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.

Download or read book Mechanisms of Migration in Fishes written by James D. McCleave and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Download or read book The Pundits written by Derek Waller and published by University Press of Kentucky. This book was released on 2014-07-11 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: On a September day in 1863, Abdul Hamid entered the Central Asian city of Yarkand. Disguised as a merchant, Hamid was actually an employee of the Survey of India, carrying concealed instruments to enable him to map the geography of the area. Hamid did not live to provide a first-hand count of his travels. Nevertheless, he was the advance guard of an elite group of Indian trans-Himalayan explorers—recruited, trained, and directed by the officers of the Great Trigonometrical Survey of India—who were to traverse much of Tibet and Central Asia during the next thirty years. Derek Waller presents the history of these explorers, who came to be called "native explorers" or "pundits" in the public documents of the Survey of India. In the closed files of the government of British India, however, they were given their true designation as spies. As they moved northward within the Indian subcontinent, the British demanded precise frontiers and sought orderly political and economic relationships with their neighbors. They were also becoming increasingly aware of and concerned with their ignorance of the geographical, political, and military complexion of the territories beyond the mountain frontiers of the Indian empire. This was particularly true of Tibet. Though use of pundits was phased out in the 1890s in favor of purely British expeditions, they gathered an immense amount of information on the topography of the region, the customs of its inhabitants, and the nature of its government and military resources. They were able to travel to places where virtually no European count venture, and did so under conditions of extreme deprivation and great danger. They are responsible for documenting an area of over one million square miles, most of it completely unknown territory to the West. Now, thanks to Waller's efforts, their contributions to history will no longer remain forgotten.

Download or read book Drift Exploration in the Canadian Cordillera written by Peter T. Bobrowsky and published by Province of British Columbia, Ministry of Energy, Mines and Petroleum Resources. This book was released on 1995 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the frequency of near-surface mineral discoveries in the British Columbia Cordillera diminishes, exploration is more frequently focused on regions of high potential but mantled by unconsolidated sediments or drift, dominated by Quaternary deposits. This volume is a compilation of papers on various aspects of drift exploration, using examples from British Columbia. Topics of the papers include Quaternary geology, recognition of paleo-flow direction, drift potential mapping, drilling methods, glacial dispersal determination using indicator clasts, till geochemistry, biogeochemical sampling, lake sedimentology, laboratory techniques, shallow seismic methods, borehole analysis, and resistivity mapping. Case studies elaborating on drift exploration concepts are dispersed throughout the compilation.

Download or read book The Cross and the River written by Ḥagai Erlikh and published by Lynne Rienner Publishers. This book was released on 2002 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing Egyptian-Ethiopian dispute over the Nile waters is potentially one of the most difficult issues on the current international agenda, central to the very life of the two countries. Analyzing the context of the dispute across a span of more than a thousand years, The Cross and the River delves into the heart of both countries' identities and cultures. Erlich deftly weaves together three themes: the political relationship between successive Ethiopian and Egyptian regimes; the complex connection between the Christian churches in the two countries; and the influence of the Nile river system on Ethiopian and Egyptian definitions of national identity and mutual perceptions of the Other. Drawing on a vast range of sources, his study is key to an understanding of a bond built on both interdependence and conflict.

Download or read book Adaptive management of fisheries in response to climate change written by ​Bahri, T., Vasconcellos, M., Welch, D.J., Johnson, J., Perry, R.I., Ma, X. & Sharma, R. and published by Food & Agriculture Org.. This book was released on 2021-02-01 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report aims to accelerate climate change adaptation implementation in fisheries management throughout the world. It showcases how flexibility can be introduced in the fisheries management cycle in order to foster adaptation, strengthen the resilience of fisheries, reduce their vulnerability to climate change, and enable managers to respond in a timely manner to the projected changes in the dynamics of marine resources and ecosystems. The publication includes a set of good practices for climate-adaptive fisheries management that have proven their effectiveness and can be adapted to different contexts, providing a range of options for stakeholders including the fishing industry, fishery managers, policymakers and others involved in decision-making. These good practices were linked to one or more of the three common climate-related impacts on fisheries resources: distributional change; productivity change; and species composition change. Therefore, these three impacts can serve as practical entry points to guide decision-makers in identifying good practice adaptation measures suitable for their local contexts. These good practices are based upon transferable experiences and lessons learned from the thirteen case studies across the globe and hopefully will contribute to greater uptake and implementation of climate-adaptive fisheries management measures on the ground.
