DOWNLOAD EBOOKSouth African temporarily open/closed estuaries (TOCEs) and similar systems along the coastlines of other regions of the world, especially Australia, are amongst the most productive aquatic ecosystems. They shift seasonally from mostly open mouth states during rainy seasons to mostly closed mouth states during the dry part of the year. This allows a whole range of juvenile forms of estuarine-dependent and estuarine-associated marine species to be recruited inside their sheltered and productive reaches, where they complete their growth to maturity. This book covers topics such as the structure and function of open/closed estuaries in South Africa, as well as outlining the future management decisions that need to be made in order to ensure the longevity of these productive ecosystems.

DOWNLOAD EBOOKSt Lucia is the world's oldest protected estuary and Africa's largest estuarine system. It is also the centerpiece of South Africa's first UNESCO World Heritage Site, the iSimangaliso Wetland Park, and has been a Ramsar Wetland of International Importance since 1986. Knowledge of its biodiversity, geological origins, hydrology, hydrodynamics and the long history of management is unique in the world. However, the impact of global change has culminated in unprecedented challenges for the conservation and management of the St Lucia system, leading to the recent initiation of a project in support of its rehabilitation and long-term sustainability. This timely volume provides a unique source of information on the functioning and management of the estuary for researchers, students and environmental managers. The insights and experiences described build on over 60 years of study and management at the site and will serve as a valuable model for similar estuaries around the world.

DOWNLOAD EBOOKOriginally published in 1981, Living Shores was for many years the standard reference for marine science students but was also embraced by a popular market for its fascinating insights into marine and coastal habitats and the life they support. After a long absence, this classic has been revived and thoroughly reworked to incorporate the many dramatic changes that our oceans and coasts have undergone over the past few decades. This book is the fi rst of a two volume set, and examines the di_ erent marine ecosystems and how humankind interacts with them. It discusses the evolution of the sea and continents and looks at the ecology of coastal systems, including intertidal zones, beaches, dunes, estuaries, islands, kelp forests and reefs. The book unpacks the relationship between humans and the marine environment, and the consequences of harvesting and mining to meet our needs. It also addresses the impact of climate change, and highlights what can be done to protect our environment. Richly supported by full-colour photography and numerous explanatory illustrations, diagrams and graphs, this book will prove invaluable to students and teachers but will also appeal to anyone with a fascination for nature and our marine world in particular.

DOWNLOAD EBOOKAlthough the main focus of this book is on the estuaries, its scope goes well beyond this particular coastal feature. Indeed, the estuary can only be considered as part of the life cycle of the entire river and the marine area it feeds into: an area particularly subject to human and natural pressures. The main estuaries and deltas of West and Central Africa region provide a variety of goods and services to its coastal population. The most important of them are related to critical fish habitat, wood and charcoal from mangroves, as well as space for agriculture, aquaculture, urban development, tourism and transport. Particular emphasis has been made in this book on mangroves that play a significant role in terms of flood control, groundwater replenishment, coastline stabilization and protection against storms. They also retain sediments and nutrients, purify water, and provide critical carbon storage. Such hydrological and ecological functions explain the focus on serving mangrove ecosystems and the nearby communities, which draw significant income from fishing, rice production, tourism, salt extraction and other activities such as harvesting honey and medicinal plants, hence the need for preserving mangrove ecosystems to ensure sustainability of the estuaries and deltas of West and Central Africa region. The book has a foreword by Mr. Achim Steiner, United Nations Under-Secretary General and Executive Director of UNEP who is stating that credible and up-to-date information is essential for the public at large but more specifically for scientists, researchers, managers, decision-makers all working together in order to safeguard, protect and sustainably manage estuaries, deltas and lagoons, and the coastal and ocean waters of Western and Central Africa.

DOWNLOAD EBOOKResearch on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.
