Jack Hranicky is a retired U.S. Government contractor, but he has been involved with archaeology as a full-time passion for over 40 years. His main interest is the Paleo-Indian period; however, he has worked in all facets of American archaeology. He has published over 250 papers and over 35 books in archaeology with his most recent being a two-volume, 800-page, 10,000-artifact book on the material culture of Virginia. In Virginia, he is considered an expert on prehistoric stone tools and rockart. The prehistoric Spout Run Observatory site was investigated by him which dated 10,470 YBP. He has served as president of the Archeological Society of Virginia (ASV) and Eastern States Archeological Federation (ESAF), and been past chairman of the Alexandria Archaeology Commission in Virginia. He is a charter member of the Registry of Professional Archaeologists (RPA). And, since he joined the Archeological Society of Virginia (ASV) in 1966, he is its senior member. And finally, his major publication is Bipoints Before Clovis.

Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.

Published with ISME, ITTO and project partners FAO, UNESCO-MAB, UNEP-WCMC and UNU-INWEH This atlas provides the first truly global assessment of the state of the world's mangroves. Written by a leading expert on mangroves with support from the top international researchers and conservation organizations, this full colour atlas contains 60 full-page maps, hundreds of photographs and illustrations and a comprehensive country-by-country assessment of mangroves. Mangroves are considered both ecologically and from a human perspective. Initial chapters provide a global view, with information on distribution, biogeography, productivity and wider ecology, as well as on human uses, economic values, threats, and approaches for mangrove management. These themes are revisited throughout the regional chapters, where the maps provide a spatial context or starting point for further exploration. The book also presents a wealth of statistics on biodiversity, habitat area, loss and economic value which provide a unique record of mangroves against which future threats and changes can be evaluated. Case-studies, written by regional experts provide insights into regional mangrove issues, including primary and potential productivity, biodiversity, and information on present and traditional uses and values and sustainable management.

Aquaculture is the farming of aquatic organisms, principally fish, molluscs, crustaceans and marine algae. It has seen phenomenal worldwide growth in the past fifty years and many people view it as the best solution for the provision of high quality protein to feed the world's growing population, particularly with the rapid decline in wild marine fish populations. Aquaculture now contributes approximately one third of the world's fish production, and has increased by about eight per cent annually over the last thirty years, while wild capture fishery production has remained static. Focused on developing more sustainable aquaculture practices, this book provides an ideal advanced-level textbook. It is based on extensive evidence and knowledge of best practices, with guidance on appropriate adaptation and uptake in a variety of environmental, geographic, socio-economic and political settings. The author concentrates on low-impact aquaculture systems and approaches, which have minimal adverse effects on the environment. He also emphasizes socially responsible and equitable aquaculture development; to enhance the natural resource base and livelihoods. Drawing on a range of case-studies from around the world, the objective is to show where progress in terms of developing ecologically sound and socially responsible forms of aquaculture has been made. A tool-box of approaches to support widespread adoption and appropriate adaptation of regenerating aquaculture strategies is provided, ensuring the book will have practical relevance for both students and professionals.
