This book was released on 2015 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Abstract: Eelgrasses serve as important nursery habitats in the Pacific Northwest for diverse marine life and are widely recognized as indicators of coastal ecological health. Seasonal differences in respiration and Photosynthesis-Irradiance (P-I) relationships of a population of marine eelgrass Zostera marina in Rosario Bay, WA were investigated in order to characterize its growth potential in different seasons. The local light availability in situ for each season was also estimated by combining direct light measurements under different conditions with hourly weather and tide measurements. Measurement of the P-I relationship of blade sections and extrapolation to whole plants demonstrated that sufficient light is present even in the lowest-light season (winter) so that clean eelgrass is able to at least support its metabolism by photosynthesis and experience net growth. However, epiphytic algae living on the blades of Z. marina likely reduces its access to light, especially in summer, and could potentially lead to light limiting conditions.

This book was released on 2007-05-16 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state regional restoration program is underway for America’s most urbanized estuary. Synthesis of the Long Island Sound ecosystem is needed to integrate knowledge across disciplines and provide insight into understanding and managing pressing issues, such as non-point sources of pollution, coastal development, global climatic change, and invasive species. Currently, there is a need for a comprehensive volume that summarizes the ecological and environmental dynamics and status of Long Island Sound and its myriad ecosystems. It has been 30 years since a comprehensive summary of Long Island Sound was prepared and 50 years since the pioneering work of Gordon Riley. Major advances in estuarine science are providing new insights into these systems, and yet, the condition of many estuaries is in decline in the face of continuing coastal development. There is an opportunity to lay a foundation for integrative coastal observing systems that truly provide the foundation for improved decision-making. This book will provide a key reference of our scientific understanding for work performed over the past three decades and guide future research and monitoring in a dynamic urbanized estuary.
Download or read book Restoration of Coastal Marine Ecosystems written by Ronald Osinga and published by Frontiers Media SA. This book was released on 2024-09-23 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human health and wellbeing cannot be sustained without proper ecosystem functioning and high biodiversity is essential to maintain such functioning. Worldwide, unsustainable exploitation of natural resources by a growing human population has imposed serious pressures on ecosystem integrity. To change the tide, the United Nations declared the current decade as the UN Decade of Ecosystem Restoration, with the aim of “supporting and scaling up efforts to prevent, halt and reverse the degradation of ecosystems worldwide”. Large-scale active ecosystem restoration actions will be needed to achieve these ambitious aims. Whereas methodologies for systemic restoration of terrestrial ecosystems have been established, marine ecosystem restoration is still a young field of science, although rapidly emerging. This Research Topic proposal aims to provide a platform for the growing number of marine scientists involved in marine ecosystem restoration. The Research Topic will focus on coastal ecosystems, such as mangrove forests, salt marshes, seagrass beds, kelp forests, shellfish reefs and coral reefs, but will also welcome studies on nearshore environments such as shelf seas, Mediterranean coralligenous habitats and mesophotic reefs.

Download or read book Marine Ecosystem Restoration MER Challenges and New Horizons written by Brian Silliman and published by Frontiers Media SA. This book was released on 2023-10-23 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, marine ecosystems have been lost and degraded due to anthropogenic disturbances. For example, oyster reefs have declined by at least ∼85%, coral reefs by ∼19%, seagrasses by ∼29%, North American salt marshes by ∼42%, and mangroves by ∼35% from the early 19th century. Deepwater reefs and deep-sea vents are not immune and have also been reduced in extent in many areas. Factors driving these losses include habitat destruction, pollution, invasive species, overfishing, trawling, mining and, more recently, climate change effects, such as ocean warming, species range changes and acidification. These habitat declines are occurring at a time when marine waters are being used at or near their maximum productive capacity to meet the contemporary needs of an ever-increasing human population. Because coastal and marine ecosystems generate some of the richest biodiversity hotspots on Earth, and provide critical ecosystem services, including storm protection, fisheries production, and carbon storage, over 1 billion US dollars have been spent globally in an attempt to halt and reverse observed declines. Early conservation efforts aimed at protecting these valuable and threatened habitats focused on reducing human impacts and physical stressors. However, with habitat degradation continuing and sometimes increasing in rate, it is now clear conservation alone will not be sufficient to protect and reestablish coastal ecosystems. Habitat restoration, although in existence for many decades, has recently been elevated as a new primary strategy to stem and even reverse coastal habitat loss. The call for increasing investment in restoration efforts has emerged with significant advances in propagule rearing and dispersion of habitat-forming organisms (e.g., oysters, seagrasses, corals). In addition, restoration resources are increasingly allocated by governments and/or large corporations with the aim to, for example, fix past landscape engineering efforts that had unintended environmental consequences. Such investments are being made to (i) provide jobs for those unemployed during economic downturns, (ii) restore ecosystems destroyed by natural disasters and stressors, (iii) increase coastal defense in response to increased frequency of intense storms, and/or (iv) compensate for pollution-and development-driven habitat degradation. Conservation practitioners have traditionally been skeptical to invest heavily in restoration at large-scales because of the high cost per area (10,000-5,000,000 US$/ha for coastal vs. 500-5,000 US$/ha for terrestrial systems) to replant coastal ecosystems and/or the high chance that the restored ecosystems will not live long (e.g. outplanted corals). For restoration to be effective and employed as a primary method of coastal conservation at relevant scales, we must improve its efficiency, lower costs and rapidly share and incorporate advances. One crucial step will be to identify when and where restoration attempts have been carried out according to state-of-art ecological theory and gauge their success. Another is generating synthesis studies that focus both within and across ecosystems to identify efficiencies, adaptations and innovations. Work that shows theoretical and methodological innovations in specific ecosystems as well as across systems will be critical to pushing all fields of MER forward. Although there is rapidly increasing interest and investment, the field of marine ecosystem restoration is just beginning to undergo synthesis. Therefore, the aim of this Research Topic is to bring together research contributions to help address this synthesis need, provide a spotlight for recent innovations, enhance our understanding of successful methods in marine ecosystem restoration and promote integration of ecological, sociological and engineering theory into restoration practices.
