Seagrasses: Biology, Ecology and Conservation

Book Description

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-ofâ€“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.

Book Description

Seagrasses, a group of about sixty species of underwater marine flowering plants, grow in the shallow marine and estuary environments of all the world's continents except Antarctica. The primary food of animals such as manatees, dugongs, green sea turtles, and critical habitat for thousands of other animal and plant species, seagrasses are also considered one of the most important shallow-marine ecosystems for humans since they play an important role in fishery production. Though they are highly valuable ecologically and economically, many seagrass habitats around the world have been completely destroyed or are now in rapid decline. The World Atlas of Seagrasses is the first authoritative and comprehensive global synthesis of the distribution and status of this critical marine habitat--which, along with mangroves and coral reefs, has been singled out for particular attention by the United Nations Convention on Biodiversity.
Illustrated throughout with color maps, photographs, tables, and more, and written by a large team of international collaborators, this unique volume covers seagrass ecology, scientific studies to date, current status, changing distributions, threatened areas, and conservation and management efforts for twenty-four regions of the world. As human populations expand and continue to live disproportionately in coastal areas, bringing new threats to seagrass habitat, a comprehensive overview of coastal resources and critical habitats is more important than ever. The World Atlas of Seagrasses will stimulate new research, conservation, and management efforts, and will help better focus priorities at the international level for these vitally important coastal ecosystems.

I bought this for the maps. I originally borrowed it from the library to aid me with my research...recent and comprehensive world maps of seagrass distribution are not that easy to come by and this book includes one for every imaginable species. It was so useful that I decided I wanted to always have it on hand. In the text it gives nice descriptions of seagrass composition for different areas of the world and in the back has drawings, distribution maps, and estimated coverage of each species. The only thing I wished it included is standard characteristics of each species in the back. This book pulls together information from a remarkable number of sources into one place and ended up saving me a lot of time and headaches.

Seagrasses: Biology, Ecology and Conservation

ASIN: 0849320453

Book Description

Seagrasses are becoming widely used as in situ indicators of the relative health and condition of subtropical and tropical estuarine ecosystems. To permit meaningful management of our estuaries, there is clearly a need to develop and refine ways of effectively monitoring and assessing seagrasses. Seagrasses: Monitoring, Ecology, Physiology, and Management includes the peer-reviewed, written results of presentations made at a recent workshop that addressed this very issue. A total of 28 original research and review chapters are organized around four major themes: Ecology and Physiology, Monitoring and Trends, Management, and Restoration. Additional research study results, not completed at the time of the workshop, are also included as they are directly related to the topic of seagrass management ecology. Overall, Seagrasses: Monitoring, Ecology, Physiology, and Management encompasses the latest research in seagrass management ecology to assist in the promotion of a dialogue between the research and environmental management communities. Not only will this work serve as a cornerstone for continued improvement in effectively monitoring the health and condition of near coastal waters, but also as a reference central to the premise that effective and efficient assessment of seagrasses will aid in estuarine ecosystem management.

Book Description

Mangroves and seagrasses form extensive and highly productive ecosystems that are biologically diverse and economically valuable. This new edition has been thoroughly revised and updated to provide a comprehensive introduction to all aspects of the biology and ecology of mangroves and seagrasses, using a global range of examples. It deals with the adaptations of these plants to their exacting environment, the rich and diverse communities of organisms that depend on mangrove forests and seagrass meadows (including tree-climbing shrimps, synchronously flashing fireflies and 'gardening' seacows), the links between mangrove, seagrass, and other habitats, the evolution, biodiversity and biogeography of mangroves and seagrasses, and the likely effects of global climate change. The economic value of mangroves and seagrasses is also discussed, including approaches to rational management of these vital resources, and techniques for the restoration of degraded habitats. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these aquatic environments although pollution, conservation and experimental aspects are also considered. The book is intended for students, naturalists and professionals and assumes no previous knowledge of mangrove or seagrass ecology.

Seagrasses: Biology, Ecology and Conservation

ASIN: 0444508910

Book Description

This thorough and informative volume presents a set of detailed, globally applicable techniques for seagrass research.
The book provides methods for all aspects of seagrass science from basic plant collection to statistical approaches and investigations of plant-animal interaction. The emphasis is on methods that are applicable in both developing and developed countries.

The importance of seagrasses in coastal and near shore environments, and ultimately their contribution to the productivity of the world's oceans, has become increasingly recognised over the last 40 years.
Seagrasses provide food for sea turtles, nearly 100 fish species, waterfowl and for the marine mammals the manatee and dugong. Seagrasses also support complex food webs by virtue of their physical structure and primary production and are well known for their role as breeding grounds and nurseries for important crustacean, finfish and shell fish populations. Seagrasses are the basis of an important detrital food chain. The plants filter nutrients and contaminants from the water, stabilise sediments and act as dampeners to wave action. Seagrasses rank with coral reefs and mangroves as some of the world's most productive coastal habitat and strong linkages among these habitats make the loss of seagrasses a contributing factor in the degradation of the world's oceans.

Contributors from around the world provide up-to-date methods for comparable collection of ecological information from both temperate and tropical seagrass ecosystems.

Book Description

Seagrass in Australia: Strategic Review and Development of an R&D Plan was commissioned by the Fisheries Research and Development Corporation (FRDC) and follows the Corporation's Fisheries Habitat Review. It reflects a shift from viewing fished species or even fisheries habitats as separate, unconnected entities to viewing them as components of larger ecosystems, and it seeks to develop a comprehensive, ecosystem-based management plan.

Description:
Land-based nutrient pollution represents a significant human threat to coral reefs globally. We examined this phenomenon in shallow seagrass and coral reef communities between the Content Keys (southern Florida Bay) and Looe Key (south of Big Pine Key) in the Lower Florida Keys by quantifying the role of physical forcing (rainfall, wind, tides) and water management on mainland South Florida to nutrient enrichment and blooms of phytoplankton, macroalgae, and seagrass epiphytes. Initial studies (Phase I) in 1996 involved daily water quality sampling (prior to, during, and following physical forcing events) at three stations (AJ, an inshore area directly impacted by sewage discharges; PR, a nearshore patch reef located inshore of Hawk Channel; and LK, an offshore bank reef at Looe Key) to assess the spatial and temporal patterns in advection of land-based nutrients to the offshore reefs. Concentrations of dissolved inorganic nitrogen (DIN=NH"4^++NO"3^-+NO"2^-), soluble reactive phosphorus (SRP), and chlorophyll a increased at PR and LK following a wind event (~15 knots, northeast) in mid-February. The highest DIN (mostly NH"4^+) and SRP concentrations of the entire study occurred at the inshore AJ during an extreme low tide in March. Following the onset of the wet season in May, mean NH"4^+ and chlorophyll a concentrations increased significantly to maximum seasonal values at PR and LK during summer; relatively low concentrations of NO"3^- and a low f-ratio (NO"3^-/NH"4^++NO"3^-) at all stations during summer do not support the hypothesis that the seasonal phytoplankton blooms resulted from upwelling of NO"3^-. A bloom of the seagrass epiphyte Cladosiphon occidentalis (phaeophyta) followed the onset of the rainy season and increased NH"4^+ concentrations at LK, resulting in very high epiphyte:blade ratios (~3:1) on Thalassia testudinum. Biomass of macroalgae increased at all three stations from relatively low values ( <50 g dry wt m^-^2) in winter and early spring to higher values (~100-300 g dry wt m^-^2) typical of eutrophic seagrass meadows and coral reefs following the onset of the rainy season. The mean @d^1^5N value of Laurencia intricata (rhodophyta) during 1996 at AJ (+4.7%%) was within the range reported for macroalgae growing on sewage nitrogen; lower values at the more offshore PR (+3.1%%) and LK (+2.9%%) were at the low end of the sewage range, indicating an offshore dilution of the sewage signal during the 1996 study. However, transient increases in @d^1^5N of Cladophora catanata (chlorophtyta) from ~+2% to +5% at LK concurrent with elevated NH"4^+ concentrations following rain and/or wind events in May and July suggest episodic advection of sewage nitrogen to the offshore LK station. The Phase II study involved sampling of macroalgae for @d^1^5N along a gradient from the Content Keys through Big Pine Key and offshore to LK in the summer wet season of 2000 and again in the drought of spring 2001. During the July 2000 sampling, macroalgae in nearshore waters around Big Pine Key had elevated @d^1^5N values (~+4%%) characteristic of sewage enrichment; lower values (~+2%%) at LK were similar to values reported for macroalgae in upstream waters of western Florida Bay influenced by nitrogen-rich Everglades runoff. That pattern contrasted with the drought sampling in March 2001, when @d^1^5N values of macroalgae were elevated (+6%%) to levels characteristic of sewage enrichment over a broad spatial scale from the Content Keys to LK. These results suggest that regional-scale agricultural runoff from the mainland Everglades watersheds as well as local sewage discharges from the Florida Keys are both significant nitrogen sources supporting eutrophication and algal blooms in seagrass and coral reef communities in the Lower Florida Keys. Hydrological and physical forcing mechanisms, including rainfall, water management on the South Florida mainland, wind, and tides, regulate the relative importance and variability of these anthropogenic nitrogen inputs over gradients extending to the offshore waters of the Florida Reef Tract.
