Available in PDF, EPUB and Kindle. Book excerpt: Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent ecosystems. Mangrove forests, a common interface habitat in tropical coastal zones, once lined much of the tropical and subtropical shores worldwide. However, anthropogenic influences on these systems have led to a ~35% reduction in mangrove area over the last fifty years. In light of the perceived importance of mangrove forests as coastal habitat, the rapid decline of this habitat type, and the potential implications of mangrove habitat loss to adjacent ecosystems, it is important to build upon the current state of knowledge for mangrove forests. The chapters in this dissertation report on the following topics. First I review the published literature to examine the available evidence for connections between mangrove forests and coral reefs. I synthesize previous research findings, highlight areas of future research priorities, and propose a conceptual model of how areas of mangrove disturbance and resulting impacts on coral reefs are related. Second, I assess the effects of mangrove clearing on the immediate habitat. I examine how the physical environment changes following mangrove clearing by examining abiotic factors. I also measure changes in algal biomass and diversity to determine what effects physical changes have on the primary producer community. My results indicate that mangrove clearing has dramatic effects on both the physical and biotic environment. Based on measured changes in abiotic and biotic conditions, K. Frasier and I investigate how larval and zooplankton communities differ between intact and cleared mangrove areas. We find that diversity and community composition differ between intact and cleared mangrove areas, highlighting an additional effect of mangrove disturbance with potential implications for adjacent systems. To address the unanswered question of whether and how abiotic and biotic changes in cleared mangrove areas impact adjacent coral reefs, I repeat and expand upon the study I had conducted on abiotic and biotic changes following mangrove removal. The results in the immediate habitat indicate that the effects of mangrove disturbance are broad. Results from the reefs indicate that mangrove disturbance does have effects on adjacent coral reefs. To determine the relative importance of mangrove-derived nutrients to adjacent coral reef ecosystems and to examine how distance from mangroves to reefs and clearing of mangroves affected energy transfer, I sample sessile reef invertebrates. I employ carbon, nitrogen and sulfur stable isotope analysis as a tool to evaluate whether sessile invertebrates: corals, sponges, a bivalve and feather duster worm, utilize mangrovederived nutrients. Though the pattern varies by taxon, this research provides evidence that sessile reef invertebrates utilize mangrove-derived nutrients. Finally, I examine the effect of two consecutive storm events, the 2005 Tropical Storm (later Category 5 Hurricane) Wilma and the subsequent Tropical Storm Gamma, on the coastal zone. The retention rate of field equipment following storm events provides a picture of how coastal protection changes following anthropogenic mangrove disturbance and the implications of continuing mangrove loss as storm frequency and intensity increase in parallel with climate change. These studies provide new evidence on the effects of disturbance to mangroves on coastal and reef systems. Many new research areas are raised by the results presented here. However, these data provide a useful framework for considering conservation and management strategies for mangrove forest? coral reef systems.

This book was released on 2009-09-23 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 that result from the mutual exchange of nutrients, organic matter, fish, and crustaceans. A group of leading authors from around the world reviews the patterns and underlying mechanisms of important biogeochemical and biological linkages among tropical coastal ecosystems in 15 chapters. Included are chapters that review cutting-edge tools to study and quantify these linkages, the importance of such linkages for fisheries, and how tropical ecosystems should be conserved and managed for sustainable use by future generations. The book uses examples from all over the world and provides an up-to-date review of the latest published literature. This book is a ‘must read’ for professionals working on the conservation, management, and ecology of mangrove, seagrass and coral reef ecosystems.

Download or read book Encyclopedia of Modern Coral Reefs written by David Hopley and published by Springer Science & Business Media. This book was released on 2010-11-26 with total page 1226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

Available in PDF, EPUB and Kindle. Book excerpt: Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental resource managers. This book addresses current and emerging threats as well as challenges and opportunities for managing corals and associated fisheries. It provides an information baseline toward a better understanding of how corals and the consequences of coral condition influence fish populations, especially as they relate to management of those populations. The book contains content from presentations modified as a result of interactions and discussions with colleagues and peer reviews by global experts in corals and fisheries. Many chapters include additional materials not presented in the workshop. There are also papers that were not presented at the workshop but contribute to the central theme of the book. Topics covered include: Global decline in coral reefs and impacts on fishery yields Distribution and diversity in the Gulf of Mexico Implementation of Coral Habitat Areas of Particular Concern (CHAPCs) Deepwater coral/sponge habitats Coral populations on offshore platforms Mangrove connectivity for sustaining coral reef fisheries Restoring deepwater coral ecosystems and fisheries after the Deepwater Horizon oil spill Predictive mapping of coral reef fish Covering a range of subject matter, most of the chapters offer suggestions for future research on the interrelationships between corals and fisheries. In addition, the final chapter presents a summary on these interrelationships and discusses managing them for the future.

Download or read book The Energetics of Mangrove Forests written by Daniel Alongi and published by Springer Science & Business Media. This book was released on 2009-01-18 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their importance in sustaining livelihoods for many people living along some of the world’s most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against coastal erosion. This book presents a functional overview of mangrove forest ecosystems; how they live and grow at the edge of tropical seas, how they play a critical role along most of the world’s tropical coasts, and how their future might look in a world affected by climate change. Such a process-oriented approach is necessary in order to further understand the role of these dynamic forests in ecosystem function, and as a first step towards developing adequate strategies for their conservation and sustainable use and management. The book will provide a valuable resource for researchers in mangrove ecology as well as reference for resource managers.

Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades since publication of the first edition, substantial advancements have been made in the science, the need for transdisciplinary approaches to coral reef protection greater than ever before. This new edition, now in full color throughout with accompanying animations, goes beyond identifying foundational information and current problems to pinpoint science-based solutions for managers, stakeholders and policy makers. Coral reefs are connected by currents that carry plankton and the larvae of many reef-based organisms. Further, they supply food to reefs. Currents also bring pollutants from the land and, together with the atmosphere, affect the surrounding ocean. The chapters in this book provide a much-needed review of the biophysics of reefs with an emphasis on the Great Barrier Reef as an ecosystem. The focus is on interactions between currents, waves, sediment and the dynamics of coastal and reef-based ecosystems. The topographic complexity of reefs redirects mainstream currents, creates tidal eddies, mushroom jets, boundary layers, stagnation zones, and this turbulence is enhanced by the oceanographic chaos in the adjoining Coral Sea. This is the environment in which particles and organisms, of a range of sizes live, from tiny plankton to megafauna. This generates faunal connectivity at scales of meters to thousands of km within the Great Barrier Reef and with the adjoining ocean. Pollution from land-use is increasing and remedial measures are described both on land and on coral cays. The impact of climate change is quantified in case studies about mangroves and corals. Modelling this biophysical complexity is increasing in sophistication, and the authors suggest how the field can advance further.
