MARINE BOTANY Second Edition Unmatched in detail and breadth, this Second Edition of MarineBotany explores the startling diversity and environmental dynamicsof the hundreds of micro- and macroalgae, seagrasses, mangroves,and salt marshes as well as phytoplankton (minute, free-floatingphotosynthetic plants) and benthic communities (attached plants)that comprise the flourishing botanical garden submerged in andaround the surface of our vast oceans. Reflecting the latest in research since the original 1981 edition,long considered the classic reference on marine plant life, thisnew edition's enhanced ecological perspective details the ongoingenvironmental challenges endured by these fragile life-forms.Viewing the structure and function of marine plant communities inthe context of abiotic (light, temperature, water movement,nutrients), biotic (photosynthesis, carbon fixation, competition,predation, symbiosis), and anthropogenic influences, the book moveslayer by layer through the ocean, capturing their photosyntheticand adaptive mechanisms. Pollution in the form of oil spills, heavyand radioactive metals, biological damage wrought from harvestingand aquaculture, and the harmful effects of ozone depletion andUV-B rays are detailed, along with the impact of environmentalfactors on morphological and anatomical adaptations. The book alsodescribes the anthropogenic stresses endured by salt marshes,mangals, seagrass communities, and marine plants of coral reefs,concluding with possible management and restorativetechniques. Marine Botany, Second Edition is both a vivid global map andcomprehensive guide to all of the flourishing forms of plant lifeat our oceans' surface, shores, and depths and the dynamics oftheir survival.

Download or read book Marine Benthic Vegetation written by Winfried Schramm and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing amounts of various types of wastes and pollutants including nutrients enter the coastal waters via rivers, direct discharges from land drainage systems, diffuse land runoff, dumping and via the atmosphere. This has led to coastal eutrophication and in extreme cases to hypertrophication. Until recently, coastal eutrophication and the resulting effects on marine macrophytes were mainly treated as local short-term problems. However, the local nearshore problems developed into overall coastal and inshore phenomena, and recently we have been facing coastal eutrophication problems on a global scale. This book is the first comprehensive document, systematically covering the entire coastline of Europe, on the effects of eutrophication on the marine benthic vegetation.

Available in PDF, EPUB and Kindle. Book excerpt: This Research Topic will coincide with an international Blue Carbon Conference at the Royal Society of Edinburgh in November 2021, during the UNFCCC COP26 climate negotiations; we seek to showcase Blue Carbon as a Nature-based Solution for Climate Change, People and Biodiversity. The conference theme identifies the growing climate mitigation opportunities presented by Blue Carbon, yet also seeks to highlight the emergent research that points to the wider climate mitigation services of carbon in the marine environment - what we are calling "beyond the inventory". We welcome contributions that address the science and policy dimensions of Blue Carbon, particularly where these highlight opportunities and mechanisms for the protection, restoration and creation of Blue Carbon habitats. We also welcome case-study examples that highlight successful partnerships in a wide range of international settings and would particularly encourage contributions that show-case legal, policy or investment opportunities.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is having an increasing impact on coastal, estuarine, and marine environments worldwide. This book provides state-of-the-art coverage of climate change effects on estuarine ecosystems from local, regional, and global perspectives. With editors among the most noted international scholars in coastal ecology and estuarine science and contributors who are world-class in their fields, the chapters in this volume consist of comprehensive studies in coastal, estuarine and marine sciences, climate change, and coastal management and provide an extensive international collection of data in tabular, illustrated, and narrative formats useful for coastal scientists, planners, and managers. Comprised of three sections: (1) physical-chemical aspects; (2) biological aspects; and (3) management aspects, the book not only examines climatic and non-climatic drivers of change affecting coastal, estuarine, and marine environments but also their interactions and effects on populations of organisms, communities, habitats, and ecosystem structure and function. Pulling together today’s most salient issues and key literature advances for those concerned with coastal management, it allows the reader to see across direct and indirect interactions among disciplinary and ecosystem boundaries. Climate Change and Estuaries meets the research needs of climate scientists, estuarine and marine biologists, marine chemists, marine geologists, hydrologists, and coastal engineers, while students, professors, administrators, and other professionals will also find it an exhaustive reference.
Download or read book Eelgrass Zostera Marina Ecosystems in Eastern Canada and Their Importance to Migratory Waterfowl written by Mélanie-Louise Leblanc and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Seagrasses are marine flowering plants that create some of the most productive coastal habitats globally and play a key role in the functioning of nearshore ecosystems. The most common seagrass genus in Canada is Zostera and the species Zostera marina (eelgrass) is the predominant seagrass in intertidal and subtidal shoreline zones along the Atlantic, Pacific, and eastern James Bay coasts. Eelgrass has specific habitat requirements, with growth and productivity optimized within particular ranges of salinity, temperature, light availability, and nutrient concentrations. Large eelgrass meadows can impact nearshore environments by filtering the water column, stabilizing sediment, buffering shorelines, and providing habitat for various marine and coastal species, including commercially important species like Atlantic cod (Gadus morhua) and lobster (Homarus americanus). Eelgrass is also a vital food resource for migratory waterfowl, notably Canada Geese (Branta canadensis), Pacific Black Brant (Branta bernicla nigricans), and Atlantic Brant (Branta bernicla hrota). Despite their ecological importance, seagrasses are among the most vulnerable coastal ecosystems on the planet. The global loss of seagrass has been linked to a variety of human activities, including pollution, invasive species, and catchment modifications. There is an urgent need to improve monitoring of seagrass responses to environmental change, better document the importance of seagrass meadows to species reliant on them for food and habitat, and advance effective management and conservation of seagrass ecosystems. In this thesis, I investigated the spatiotemporal dynamics of eelgrass meadows in eastern Canada and the importance of eelgrass as a food source for migratory waterfowl, using remote sensing data, long-term monitoring data (biomass, density, and cover), and field observations. In Chapter 3, I used a novel cost-efficient approach for satellite imaging time-series to examine changes in eelgrass distribution and abundance from 1984 to 2017 in a wetland of international importance in northeastern New Brunswick. With minimal ground truth data, the novel time-series approach revealed a slow and steady decline in eelgrass abundance in some areas of the estuary. In contrast, other areas were characterized by highly dynamic shifts in eelgrass cover over time. I demonstrated how time-series analysis can be used to identify potential drivers of seagrass change and the benefits of including time-series analysis in seagrass monitoring programs. In Chapter 4, I contributed to advancing knowledge of migratory waterfowl stopover behaviour by examining the influence of eelgrass and human activities on Canada Geese habitat selection. Combining field observations of Canada Geese and the eelgrass distribution maps produced in Chapter 3, I found that Canada Geese selected areas with high eelgrass availability during periods of low human disturbance, which emphasized the importance of eelgrass as a food source during the fall migration. However, higher levels of human disturbance led to a redistribution of geese away from dense eelgrass meadows. In Chapter 5, I presented new insights into the recent and current state of eelgrass along the eastern coast of James Bay after a drastic and large-scale decline in the late 1990s. By aggregating, synthesizing, and analyzing long-term monitoring data and current surveys, spanning 1982 - 2020, I provided the first quantitative evidence that changes in eelgrass biomass in northeastern James Bay may reflect synergistic impacts of climate change and altered freshwater discharge regimes. Overall, this thesis advances understanding of how temperate and subarctic Zostera marina ecosystems and associated fauna respond to coastal development and climate change"--
