Mangrove forests, seagrass beds, and coral reefs are circumtropical ecosystems that are highly productive, and provide many important biological functions and economic services. These ecosystems cover large surface areas in the shallow tropical coastal seascape but have suffered from serious human degradation, especially in the last few decades. Part of their diversity, productivity, and functioning seems to be based on their juxtaposition. Especially in the last decade significant advances have been made on new insights into their ecological connectivity. This authoritative book provides a first-time comprehensive review of the major ecological interactions across tropical marine ecosystems...
Written by an outstanding group of contributors, this book examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them, most notably nutrient over-enrichment from coastal watersheds and airsheds. The contributors target the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms and other climate effects, and the resulting biotic and ecosystem impairments that have developed. The book compares biogeochemical and ecological response to nutrient enrichment and other pollutants in lagoonal estuaries to those in other estuarine types.
With the increasing interest of pop culture and academia towards environmental issues, which has simultaneously given rise to fiction and artworks dealing with interdisciplinary issues, climate change is an undeniable reality of our time. In accordance with the severe environmental degradation and health crises today, including the COVID-19 pandemic, human beings are awakening to this reality through climate fiction (cli-fi), which depicts ways to deal with the anthropogenic transformations on Earth through apocalyptic worlds as displayed in works of literature, media and art. Appealing to a wide range of readers, from NGOs to students, this book fills a gap in the fields of literature, media and art, and sheds light on the inevitable interconnection of humankind with the nonhuman environment through effective descriptions of associable conditions in the works of climate fiction.
In the heart of Africa, a unique lake attracts the attention of scientists since the beginning of the 20th century. At the foot of the Virunga volcano chain, Lake Kivu harbors a vast amount of dissolved carbon dioxide and methane, making this lake the most dangerous lake on Earth. But the lake furnishes also many goods and services for surrounding populations and may soon become the most important energy supplier in the area. At the beginning of gas exploitation, the time has come for gathering the large amount of scientific information acquired during past and present research on Lake Kivu. The eleven chapters cover many aspects of the physics, geochemistry and biology of the lake, with a particular focus on the unique physical and geochemical features of the water column and on the ecological functioning of the surface waters. The impacts of the introduced fish species and the potential impacts of methane exploitation are also summarized. This multi-disciplinary book may also be used as an introduction to the limnology and biogeochemistry of large tropical lakes, as it covers various aspects of the physics, geochemistry, biology and ecology of the African Great Rift lakes.
Wetlands occur at the interface of upland and aquatic ecosystems, making them unique environments that are vital to ecosystem health. But wetlands are also challenging to assess and understand. Wetland researchers have developed specialized analytical methods and sampling techniques that are now assembled for the first time in one volume. More than 100 experts provide key methods for sampling, quantifying, and characterizing wetlands, including wetland soils, plant communities and processes, nutrients, greenhouse gas fluxes,redox-active elements, toxins, transport processes, wetland water budgets,and more.
Available online: https://pub.norden.org/temanord2022-506/ This study shows that we can use satellite imagery to map Nordic salt marshes with an accuracy of 70%. It also shows how we can use satellite imagery to estimate their carbon storage potential. By knowing where our salt marshes are – the Nordic region is better suited to manage these coastal areas sustainably. A step towards achieving our Nordic Vision to become the most sustainable and integrated region in the world by 2030.
The Afrotropical Streams and Rivers: Structure, Ecological Processes and Management is a comprehensive guide that provides assessment of major rivers and tributaries in Africa. Unlike other books available, the editors present a thorough study of geomorphological, hydrological, biological, and ecological processes incorporating a range of plant and animal communities, while considering implications of human communities that depend upon them. This book, edited by a diverse cohort of researchers and/or scholars, is intended as an educational and practical guide for graduate students, researchers and scientists who focus on the biodiversity, conservation and management/policy issues of the African river systems. - Provides a comprehensive introduction to African freshwater rivers, their biota, and abiotic processes. - Contains unique case studies on African streams and rivers. - Organised around an interdisciplinary approach that covers the complex aspects of conservation and management of African river systems on the continent.
The excavation of shell middens and mounds is an important source of information regarding past human diet, settlement, technology, and paleoenvironments. The contributors to this book introduce new ways to study shell-matrix sites, ranging from the geochemical analysis of shellfish to the interpretation of human remains buried within. Drawing upon examples from around the world, this is one of the only books to offer a global perspective on the archaeology of shell-matrix sites. “A substantial contribution to the literature on the subject and . . . essential reading for archaeologists and others who work on this type of site.”—Barbara Voorhies, University of California, Santa Barbara, author of Coastal Collectors in the Holocene: The Chantuto People of Southwest Mexico
Mangroves serve as one of the nature-based solutions for coastal communities. We are now almost at the tipping point where we can restore mangroves ecologically to mitigate climate change and enhance other important ecosystem services under the United Nations Decade on Ecosystem Restoration. Mangrove Ecosystem Restoration focuses on mangrove ecosystem restoration, the ecosystem services mangroves provide, and how to manage and conserve mangroves. The three sections include eight chapters that cover such topics as evaluating mangrove degradation, forest recovery through seedling recruitment, natural regeneration of mangroves, advanced molecular biology for restoring mangroves, and more.
