Seagrasses occur in coastal zones throughout the world, in the part of the marine habitat that is most heavily influenced by humans. Decisions about coastal management therefore often involve seagrasses, but a full appreciation of the role of seagrasses in coastal ecosystems has yet to be reached. This book provides an entry point for those wishing to learn about the ecology of this fascinating group of plants, and gives a broad overview of current knowledge, complemented by extensive literature references to guide the reader to more detailed studies.
Seagrasses are unique plants; the only group of flowering plants to recolonise the sea. They occur on every continental margin, except Antarctica, and form ecosystems which have important roles in fisheries, fish nursery grounds, prawn fisheries, habitat diversity and sediment stabilisation. Over the last two decades there has been an explosion of research and information on all aspects of seagrass biology. However the compilation of all this work into one book has not been attempted previously. In this book experts in 26 areas of seagrass biology present their work in chapters which are state-of–the-art and designed to be useful to students and researchers alike. The book not only focuses on what has been discovered but what exciting areas are left to discover. The book is divided into sections on taxonomy, anatomy, reproduction, ecology, physiology, fisheries, management, conservation and landscape ecology. It is destined to become the chosen text on seagrasses for any marine biology course.
Seagrasses are flowering plants from one of four plant families, all in the order Alismatales, which grow in marine, fully-saline environments. Seagrasses are sometimes labeled ecosystem engineers, because they partly create their own habitat: the leaves slow down water-currents increasing sedimentation, and the seagrass roots and rhizomes stabilize the seabed. Their importance for associated species is mainly due to provision of shelter, and for their extraordinarily high rate of primary production. This book presents current research in the study of seagrass, including ecosystem modeling of seagrass beds; P. oceanica population genetics and proteomics; the impact of hurricanes on seagrass thalassia testudinum in the Caribbean Sea; GIS mapping of seagrass meadows; and the rise of Ruppia in seagrass beds.
Based on research in Bolinao, this book assesses the importance of small-scale disturbance by burrowing shrimps. It covers the distribution of burrowing shrimp disturbance, the behavior of the snapping shrimp Alpheus macellarius in situ and as observed from tank experiments, and the effects of short-term burial and leaf clipping on the growth patterns of the dominant seagrass Thalassia hemprichii. The book examines the role of bioturbation by burrowing shrimps in seagrass meadows, foraging strategies of A. macellarius and its mutualistic symbiosis with Cryptocentrus spp., shrimp disturbance and T. hemprichii, and small-scale disturbance and large-scale dynamics.
Marine Ecology: Processes, Systems, and Impacts offers a carefully balanced and stimulating survey of marine ecology, introducing the key processes and systems from which the marine environment is formed, and the issues and challenges which surround its future conservation.
Seagrasses are becoming widely used as in situ indicators of the relative health and condition of subtropical and tropical estuarine ecosystems. To permit meaningful management of our estuaries, there is clearly a need to develop and refine ways of effectively monitoring and assessing seagrasses. Seagrasses: Monitoring, Ecology, Physiology, and Management includes the peer-reviewed, written results of presentations made at a recent workshop that addressed this very issue. A total of 28 original research and review chapters are organized around four major themes: Ecology and Physiology, Monitoring and Trends, Management, and Restoration. Additional research study results, not completed at the time of the workshop, are also included as they are directly related to the topic of seagrass management ecology. Overall, Seagrasses: Monitoring, Ecology, Physiology, and Management encompasses the latest research in seagrass management ecology to assist in the promotion of a dialogue between the research and environmental management communities. Not only will this work serve as a cornerstone for continued improvement in effectively monitoring the health and condition of near coastal waters, but also as a reference central to the premise that effective and efficient assessment of seagrasses will aid in estuarine ecosystem management.
Located between the Pacific and Indian Oceans, and between the Asian and Australian continents, the seas of the Indonesian Archipelago have a significant role in global weather patterns and oceanic circulation. The dynamic interplay between geological, physical, chemical, and biological processes, past and present, has given rise to one of the most diverse marine regions on the planet. Using maps and numerous illustrations, This text describes the complex coastal and marine ecosystems of the region in detail. Discussion of development, resource use and ecologically sustainable management plans is also incorporated.
This book provides insights into various aspects of marine faunal communities in India, which are extremely diverse due to the geomorphologic and climatic variations along the Indian coasts. Consisting of 30 chapters by experts in their respective fields, it is divided into two parts: · Part I: Tropical Marine Faunal Communities · Part II: Ecology and Conservation Part I highlights the diversity and distribution of Foraminifera; sponges associated with seagrass; Polychaeta; Opisthobranchia; oysters; copepods; horseshoe and brachyuran crabs; echinoderms; ascidians; fishes; fish parasites; and sea mammals. Topics of Part II include the status and environmental parameters of benthos; the status of coral reefs; the invasion of snowflake coral; the recovery of bleached corals; the socioeconomics and management of dugong; marine biodiversity conservation and management in India; the assessment of the marine fauna of the Indian Wildlife Protection Act; and marine biodiversity protected areas in India. This book will serve as a valuable reference work for marine scientists, as well as for environmental managers and policy makers.
Mangroves and seagrasses form extensive and highly productive ecosystems that are both biologically diverse and economically valuable. This book, now in its third edition and fully updated throughout, continues to provide a current and comprehensive introduction to all aspects of the biology and ecology of mangroves and seagrasses. Using a global range of examples and case studies, it describes the unique adaptations of these plants to their exacting environments; the rich and diverse communities of organisms that depend on mangrove forests and seagrass meadows (including tree-climbing shrimps, synchronously flashing fireflies, and 'gardening' seacows); the links between mangrove, seagrass, and other habitats; and the evolution, biodiversity, and biogeography of mangroves and seagrasses. The economic value of mangroves and seagrasses is also discussed, including approaches to rational management of these vital resources and techniques for the restoration of degraded habitats. A final chapter, new to this edition, examines the potential effects of global climate change including sea level rise. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these fascinating aquatic ecosystems although pollution, conservation, and experimental aspects are also considered. This accessible textbook assumes no previous knowledge of mangrove or seagrass ecology and is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers.
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
The earth where we live is the only planet of our solar system that holds a mass of water we know as the ocean, covering 70.8% of the earth's surface with a mean depth of 3,800 m. When using the term ocean, we mean not only the water and what it contains, but also the bottom that supports the water mass above and the atmosphere on the sea surface. Modern oceanography thus deals with the water, the bottom of the ocean, and the air thereon. In addition, varied interactions take place between the ocean and the land so that such interface areas are also extended domains of oceanography. In ancient times our ancestors took an interest in nearshore seas, making them an object of constant study. Deep seas, on the other hand, largely remained an area beyond their reach. Modern academic research on deep seas is said to have been started by the first round-the-world voyage of Her Majesty's R/V Challenger I from 1872 to 1876. It has been only 120 years since the British ship leftPortsmouth on this voyage, so oceanography can thus be considered still a young science on its way to full maturity.
Marine Ecology is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The ocean is the largest biome on the biosphere, and the place where life first evolved. Life in a viscous fluid, such as seawater, imposed particular constraints on the structure and functioning of ecosystems, impinging on all relevant aspects of ecology, including the spatial and time scales of variability, the dispersal of organisms, and the connectivity between populations and ecosystems. The Theme on Marine Ecology discusses matters of great relevance to our world such as: Productivity of the Oceans; Adaptations to Life in the Oceans. Pelagic Macrofauna; Marine Benthic Flora; Life in Extreme Ocean Environments; Population Dynamics of Phytoplankton; Marine Reptiles: Adaptations, Taxonomy, Distribution and Life Cycles. This volume is aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
Examines the ecological issues of marine ecosytems in unprecedented scope and depth. With contributions from an impressive group of Australian and New Zealand authors.
Seagrasses are a vital and widespread but often overlooked coastal marine habitat. This volume provides a global survey of their distribution and conservation status.
This book began life as a series of lectures given to second andthird year undergraduates at Oxford University. Theselectures were designed to give students insights as to how marineecosystems functioned, how they were being affected by natural andhuman interventions, and how we might be able to conserve them andmanage them sustainably for the good of people, both recreationallyand economically. This book presents 10 chapters, beginningwith principles of oceanography important to ecology, throughdiscussions of the magnitude of marine biodiversity and the factorsinfluencing it, the functioning of marine ecosystems at withintrophic levels such as primary production, competition anddispersal, to different trophic level interactions such asherbivory, predation and parasitism. The final three chapterslook at the more applied aspects of marine ecology, discussionfisheries, human impacts, and management and conservation. Other textbooks covering similar topics tend to treat the topicsfrom the point of view of separate ecosystems, with chapters onreefs, rocks and deep sea. This book however is topic drivenas described above, and each chapter makes full use of examplesfrom all appropriate marine ecosystems. The book is illustratedthroughout with many full colour diagrams and high qualityphotographs. The book is aimed at undergraduate and graduate students atcolleges and universities, and it is hoped that the many examplesfrom all over the world will provide global relevance andinterest. Both authors have long experience of research and teaching inmarine ecology. Martin Speight’s first degree was inmarine zoology at UCNW Bangor, and he has taught marine ecology andconservation at Oxford for 25 years. His research studentsstudy tropical marine ecology from the Caribbean through EastAfrica to the Far East. Peter Henderson is a Senior ResearchAssociate at the University of Oxford, and is Director of PiscesConservation in the UK. He has worked on marine andfreshwater fisheries, as well as ecological and economic impactsand exploitation of the sea in North and South America as well asEurope.
