Asia-Pacific Symposium on Mangrove Ecosystems


Book Description

Mangrove ecosystems are typical formations found in coastal deposits of mud and silt throughout the tropics and some distance into the subtropical latitudes. The total wordwide mangrove area, which is estimated at about 170,000 km2 with some sixty species of trees and shrubs exclusive to the habitat, dominates approximately 75% of the world's coastline between latitudes 25°N and 25°S. Such unique intertidal ecosystems support genetically diverse communities of terrestrial and aquatic organisms that are of direct or indirect socioeconomic values. Mangrove forests play important roles as coastal stabilization and protection against winds and storms; producers of nutrients, forest resources and animal species of economic importance. Recently, the issues on the conservation, proper utilization and management of mangrove forests have been widely discussed. Unfortunately, overexploitation and destruction of mangroves seriously threatens the sustainability of such a unique ecosystem. This volume includes papers on three main areas: recent advances in mangrove ecology; application and utilization of mangrove resources; and conservation and management of the ecosystems.




Aspects of Littorinid Biology


Book Description

Members of the family Littorinidae are among the most widely studied gastropod molluscs and the more questions we answer about this group, the more questions are inevitably posed. Littorinid research spans diverse disciplines, from molecular biology, physiology, ecology, systematics and evolutionary biology to elegant anatomical studies. The papers n this volume reflect the current research being carried out on littorinids, and fall into three broad themes: systematics, ecology, and pollution studies. This book is primarily targeted at the research level, while providing useful information for advanced first-degree students conducting research projects.










Biology and Evolution of the Mollusca, Volume 1


Book Description

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.




The Excavation of Nong Nor


Book Description

Nong Nor is a prehistoric coastal site located in the Chonburi Province, Southeast Asia. It was excavated between 1991 and 1993 and shows two phases of occupation: the first, c.2500 BC, a brief stay by a community of hunter-gatherers living on shellfish, dolphins and sharks; the second, an extensive cemetery of 170 graves dating to 1100-700 BC, some with grave goods and a small group of unusually wealthy ones. The authors, in their conclusion, suggest that the first inhabitants of Nong Nor may have been ancestral to the later inhabitants of nearby Khok Phanom Di.
