Marine sediments support complex interactions between macro-and microorganisms that have global implications for carbon and nutrient cycles. What is the state of the science on such interactions from coastal and estuarine environments to the deep sea? How does such knowledge effect environmental management? And what does future research hold in store for scientists, engineers, resource managers, and educators?Interactions between Macro- and Microorganisms in Marine Sediments responds to these questions, and more, by focusing on:? Interactions between plants, microorganisms, and marine sediment? Interactions between animals, microorganisms, and marine sediment? Interactions between macro- and microorganisms and the structuring of benthic communities? Impact of macrobenthic activity on microbially-mediated geochemical cycles in sediments? Conceptual and numeric models of diagenesis that incorporate interactions between macro- and microorganismsHere is an authoritative overview of the research, experimentation and modeling approaches now in use in our rapidly evolving understanding of life in marine sediments.

As researchers try to predict the effects of human modification at all trophic levels and mediate the impact of rapid environmental change, it has become clear it is no longer a matter of agreeing that both bottom-up and top-down forces play important roles in diverse ecosystems. Rather, the question is: how do these forces interact across aquatic and terrestrial systems? Written by leading experts in the field, this book presents a unique synthesis of trophic relationships within and across ecosystems that is a valuable foundation for the development of cross-system, multidisciplinary research. It also provides new insights into population biology and community ecology and examines the interactive effects of bottom-up and top-down forces on biodiversity at each trophic level. A one-stop resource for learning about bottom-up and top-down interactions, this book encourages discussion and collaboration among researchers to identify similarities and differences in trophic interactions across aquatic and terrestrial systems.

Estuaries are among the most biologically productive ecosystems on the planet--critical to the life cycles of fish, other aquatic animals, and the creatures which feed on them. Estuarine Ecology, Second Edition, covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems. Authored by a team of world experts from the estuarine science community, this long-awaited, full-color edition includes new chapters covering phytoplankton, seagrasses, coastal marshes, mangroves, benthic algae, Integrated Coastal Zone Management techniques, and the effects of global climate change. It also features an entriely new section on estuarine ecosystem processes, trophic webs, ecosystem metabolism, and the interactions between estuaries and other ecosystems such as wetlands and marshes

(A) Graphical depiction of atmospheric warming and increasing atmospheric carbon dioxide (CO2atm), which drives ocean warming, contribute to the decreases in dissolved oxygen (DO), and lowers pH and saturation state index of calcium carbonate (Ω). The partial pressure of CO2 (pCO2) increases due to increasing atmospheric CO2 that is absorbed into the seawater (i.e., ocean acidification), along with other biological processes in the marine environment.

Community ecology is the study of the interactions between populations of co-existing species. Co-edited by two prominent community ecologists and featuring contributions from top researchers in the field, this book provides a survey of the state-of-the-art in both the theory and applications of the discipline. It pays special attention to topology, dynamics, and the importance of spatial and temporal scale while also looking at applications to emerging problems in human-dominated ecosystems (including the restoration and reconstruction of viable communities). Community Ecology: Processes, Models, and Applications adopts a mainly theoretical approach and focuses on the use of network-based theory, which remains little explored in standard community ecology textbooks. The book includes discussion of the effects of biotic invasions on natural communities; the linking of ecological network structure to empirically measured community properties and dynamics; the effects of evolution on community patterns and processes; and the integration of fundamental interactions into ecological networks. A final chapter indicates future research directions for the discipline.

This book informs readers on the ecology, ecosystem services, and management of Sundaland wetland ecosystems, discussing the concepts and tools necessary to conserve these imperiled habitats. Sundaland is a biogeographically defined area of South East Asia characterised by an exceptional concentration of endemic species. The unprecedented loss of wetland habitats within Sundaland warrants urgency in implementing conservation actions. The authors are both researchers who have witnessed the ongoing losses of wetland habitats in Sundaland. The first chapter introduces fundamental concepts of ecosystems, ecological processes and ecosystem services of coastal and inland wetlands. The second chapter provides an overview of the global and regional conservation status of these ecosystems. The third chapter advances the importance of wetlands management at the landscape level (drainage basins), and proposes to adopt the concept of Ecotonal Networks (ENTs) as a sustainable management method, within the theoretical framework of Resilience Theory. The fourth chapter showcases potential flagship species that can aid in raising awareness on these endangered but poorly-known ecosystems. The fifth chapter discusses sustainable ecotourism as a viable and profitable industry to manage non-urban wetland areas of Sundaland, while providing specific suggestions for future developments. The book is written for ecosystem managers, conservation scientists, ecologists, and nature enthusiasts. It consists of a coherently arranged set of scientifically accurate tools that consider societal, cultural, and economic factors to succeed in the conservation of the Sundaland wetlands, as well as other wetland habitats in the world.

ANOXIA defines the lack of free molecular oxygen in an environment. In the presence of organic matter, anaerobic prokaryotes produce compounds such as free radicals, hydrogen sulfide, or methane that are typically toxic to aerobes. The concomitance of suppressed respiration and presence of toxic substances suggests these habitats are inhospitable to Eukaryota. Ecologists sometimes term such environments 'Death Zones'. This book presents, however, a collection of remarkable adaptations to anoxia, observed in Eukaryotes such as protists, animals, plants and fungi. Case studies provide evidence for controlled beneficial use of anoxia by, for example, modification of free radicals, use of alternative electron donors for anaerobic metabolic pathways, and employment of anaerobic symbionts. The complex, interwoven existence of oxic and anoxic conditions in space and time is also highlighted as is the idea that eukaryotic inhabitation of anoxic habitats was established early in Earth history.

Dynamic Sedimentary Environments of Mangrove Coasts provides knowledge on the importance of sedimentary dynamics in managing mangrove forests. In the first part of the book, the editors seamlessly offer a general introduction of mangrove sedimentary dynamics. This leads into more in-depth information on soil surface elevation change, sea level rise, and the importance of sedimentary dynamics in the loss or gain of blue carbon. The book concludes the discussion of mangrove sedimentary dynamics by addressing the issues of climate change (e.g. sea level rise and blue carbon) on mangrove restoration and sediment.This book will assist coastal managers and academics in addressing the gaps in mangrove restoration and coastal management. As such, it will be a valuable reference for advanced undergraduate students, graduate students, researchers, academics in the field of coastal restoration, and coastal management practitioners. - Provides a state-of-the-art summary of research into sedimentary dynamics in mangrove forests - Includes updates on issues of climate change-relevant to mangroves, such as blue carbon and sea level rise - Presents scientific background and successful case studies for mangrove restoration that can solve problems relating to mangrove management
