Waterbird Populations and Pressures in the Baltic Sea
Author: Henrik SkovPublisher: Nordic Council of Ministers
ISBN: 9289322497
Category : Bird populations
Languages : en
Pages : 203
Book Description
This report outlines the results of the internationally coordinated census of wintering waterbirds in the Baltic Sea 2007-2009 undertaken under the SOWBAS project (Status of wintering Waterbird populations in the Baltic Sea). The estimated total number of wintering waterbirds was 4.41 million compared to 7.44 million during the last co-ordinated census 1992-1993. Despite the general declines stable or increasing populations of herbivorous species were recorded. While benthic carnivores with a coastal distribution have either shown moderate declines, stable or increasing populations seaducks with an offshore distribution have declined seriously. Based on analyses of trends in wintering waterbirds and pressures indicators are suggested as performance indicators in relation to the international and national actions taken to reduce the anthropogenic pressures in the Baltic Sea.

Seagrasses: Biology, Ecology and Conservation
Author: Anthony LarkumPublisher: Springer Science & Business Media
ISBN: 9781402029424
Category : Science
Languages : en
Pages : 724
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-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.
The Maputo Bay Ecosystem

ISBN: 9789987955930
Category : Biotic communities
Languages : en
Pages : 427
Book Description
Maputo Bay comprises the most studied piece of marine water in Mozambique. It harbours extensive critical habitats, such as mangove forests, seagrass meadows and some of the southernmost reef building corals. The Bay is also an important fishing ground, second only to Sofala Bank, especially when it comes to shallow-water shrimp in Mozambique. Maputo Bay is home to high marine biodiversity including several species of special concern such as dugongs, dolphins, turtles, sharks, whales, seahorses, endangered bivalves and vulnerable seagrass Zostera. The book is aimed at decision-makers and managers and is a compilation of research undertaken by numerous researchers from institutions in Mozambique, South Africa, Portugal, Norway, Sweden and the USA.
Photosynthesis in the Marine Environment
Author: Sven BeerPublisher: John Wiley & Sons
ISBN: 1119979579
Category : Science
Languages : en
Pages : 229
Book Description
"Marine photosynthesis provides for at least half of the primary production worldwide..." Photosynthesis in the Marine Environment constitutes a comprehensive explanation of photosynthetic processes as related to the special environment in which marine plants live. The first part of the book introduces the different photosynthesising organisms of the various marine habitats: the phytoplankton (both cyanobacteria and eukaryotes) in open waters, and macroalgae, marine angiosperms and photosymbiont-containing invertebrates in those benthic environments where there is enough light for photosynthesis to support growth, and describes how these organisms evolved. The special properties of seawater for sustaining primary production are then considered, and the two main differences between terrestrial and marine environments in supporting photosynthesis and plant growth are examined, namely irradiance and inorganic carbon. The second part of the book outlines the general mechanisms of photosynthesis, and then points towards the differences in light-capturing and carbon acquisition between terrestrial and marine plants. This is followed by discussing the need for a CO2 concentrating mechanism in most of the latter, and a description of how such mechanisms function in different marine plants. Part three deals with the various ways in which photosynthesis can be measured for marine plants, with an emphasis on novel in situ measurements, including discussions of the extent to which such measurements can serve as a proxy for plant growth and productivity. The final chapters of the book are devoted to ecological aspects of marine plant photosynthesis and growth, including predictions for the future.
Seagrass Ecology
Author: Marten A. HemmingaPublisher: Cambridge University Press
ISBN: 0521661846
Category : Nature
Languages : en
Pages : 310
Book Description
Seagrasses occur in coastal zones throughout the world, in the part of the marine habitat that is most heavily influenced by humans. Decisions about coastal management therefore often involve seagrasses, but a full appreciation of the role of seagrasses in coastal ecosystems has yet to be reached. This book provides an entry point for those wishing to learn about the ecology of this fascinating group of plants, and gives a broad overview of current knowledge, complemented by extensive literature references to guide the reader to more detailed studies.

Managing Seagrasses for Resilience to Climate Change
Author: Mats BjörkPublisher: IUCN
ISBN: 2831710898
Category : Climatic changes
Languages : en
Pages : 60
Book Description
Seagrasses are flowering plants that thrive in shallow oceanic and estuarine waters around the world. Although there are only about 60 species of seagrasses worldwide, these plants play an important role in many shallow, near-shore, marine ecosystems. There is growing evidence that seagrasses are declining globally because of anthropogenic impacts. This paper presents an overview of seagrasses, the impacts of climate change, and other threats to seagrass habitats. Finally, it proposes tools and strategies for managers to help support seagrass resilience.
