Ecology and Management of Tidal MarshesA Model from the Gulf of Mexico
Author: Charles L. CoultasPublisher: CRC Press
ISBN: 9781574440263
Category : Technology & Engineering
Languages : en
Pages : 382
Book Description
This is a major compendium of the existing knowledge of the ecology and management of tidal marshes by some of the leading experts in the field. The major theme of the book is the interconnectedness of the marsh, plants, marine organisms, soils and geology, energy and money flow, and legal and management effects on the system. Emphasis is placed throughout on the fact that nature has provided a free service that can either be maintained and enhanced by man or destroyed and forever lost. At a time of declining fisheries, this book points the way to management strategies that are needed to effect improvement.
The Ecology of a Salt Marsh

Book Description
Ecologists have two long-standing ways to study large ecosystems such as lakes, forests, and salt-marsh estuaries. In the first, which G. E. Hutchinson has called the holological approach, the whole ecosystem is first studied as a "black box," and its components are investigated as needed. In the second, which Hutchinson has called the merological approach, the parts of the system are studied first, and an attempt is then made to build up the whole from them. For long-term studies, the holological approach has special advantages, since the general patterns and tentative hypotheses that are first worked out help direct attention to the components of the system which need to be studied in greater detail. In this approach, teams of investigators focus on major func tions and hypotheses and thereby coordinate their independent study efforts. Thus, although there have been waves, as it were, of investigators and graduate students working on different aspects of the Georgia salt-marsh estuaries (personnel at the Marine Institute on Sapelo Island changes every few years), the emphasis on the holo logical approach has resulted in a highly differentiated and well-coordinated long-term study. Very briefly, the history of the salt-marsh studies can be outlined as follows. First, the general patterns of food chains and other energy flows in the marshes and creeks were worked out, and the nature of imports and exports to and from the system and its subsystems were delimited.
Estuarine Comparisons
Author: Victor S KennedyPublisher: Elsevier
ISBN: 1483257851
Category : Science
Languages : en
Pages : 728
Book Description
Estuarine Comparisons compares the knowledge gained about many of the world's estuaries. The book compares the Pacific, Gulf, and Atlantic coast estuaries, and the physical, chemical, and biological parameters in estuaries throughout the world. The text also compares the features of North Sea, east and West Atlantic, Gulf, and Pacific estuaries, as well as of pioneering work in the Chang Jiang estuary of China, one of the largest in the world. Comparisons of anadromous fisheries, estuarine microbiology, and many other interactive features over a wide variety of latitudinal and longitudinal variation are also encompassed. People interested in estuaries, including ecologists, will find the book invaluable.
Integration of Ecosystem Theories: A Pattern
Author: Sven Erik JørgensenPublisher: Springer Science & Business Media
ISBN: 9401157480
Category : Science
Languages : en
Pages : 394
Book Description
The book integrates for the first time existing ecosystem theories and is therefore able to present a full ecological and theoretical pattern. It shows that we are able to understand ecosystems and their reactions, provided that we use all basic systems ecology for different aspects of ecosystem properties. The first edition of this book was published in 1992. This second edition contains the many recently published and presented contributions on ecosystem theories, which show even more strongly that an integration of the existing ecosystem theories is needed and also possible.
Coastal-Offshore Ecosystem Interactions
Author: Bengt-Owe JanssonPublisher: Springer Science & Business Media
ISBN: 3642524524
Category : Science
Languages : en
Pages : 376
Book Description
stable isotope ratios act as naturally-occurring tracers for organic matter, making possible, under certain conditions, the quantification of coastal-offshore exchanges. In general, organic matter has isotope ratios characteristic of its origin (e. g. plants with different modes of photosynthesis and different growth conditions, anthropogenic compounds). These ratios are maintained as the organic matter moves through the biosphere and geosphere. A mixture of organic matter from two sources has isotope ratios intermediate between those of the two sources, in proportion to the fraction of material from each source. Isotope ratios are one of the few methods which can trace organic matter as it moves through natural ecosystems. Ratios can be measured on both the total organic matter and on particular chemical fractions or compounds. When used on organisms, isotope ratios provide information of organic matter actually assimilated into body tissues, not just material ingested. As with all tools, this method has certain limitations which must be borne in mind when interpreting its results. Firstly, specific environmental conditions must be met. This generally means an ecosystem with a limited and known number of sources of organic matter having different isotope ratios. Two sources with different isotope ratios are ideal; additional sources with other isotope ratios complicate interpretation. Secondly, the difference in isotope ratios of the two sources should be large compared with analytical variability. Thirdly, the ratios within each source should vary as little as possible.
