Download or read book Diversity and Eco Physiological Responses of Aquatic Plants written by Chunhua Liu and published by Frontiers Media SA. This book was released on 2020-06-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic plants refer to a diverse group of aquatic photosynthetic organisms large enough to be seem with the naked eye, and the vegetative parts of which actively grow either permanently or periodically (for at least several weeks each year) submerged below, floating on, or growing up through the water surface. These include aquatic vascular plants, aquatic mosses and some larger algae. Aquatic plants are grouped into life forms, each of which relates differently to limiting factors and has distinct ecological functions in aquatic ecosystems. Life form groups include emergent macrophytes (plants that are rooted in sediment or soils that are periodically inundated, with all other structures extending into the air), floating-leaved macrophytes (rooted plants with leaves that float on the water surface), submersed macrophytes (rooted plants growing completely submerged), free submerged macrophytes (which are not rooted but attached to other macrophytes or submerged structures) and free-floating macrophytes (plants that float on the water surface). Aquatic plants play an important role in the structure and function of aquatic ecosystems by altering water movement regimes, providing shelter and refuge and serving as a food source. In addition, aquatic plants produce large standing crops which can also stabilize sediments, accumulate large amounts of nutrients thus improving water healthy. Thus, because of their ecological role, aquatic plants are an important component of aquatic ecosystems. Aquatic plants are very vulnerable to human activities and global changes, and many species of the plants had become endangered in the past several decades due to habitat loss, flooding, damming, over foraging, biological invasion and eutrophication, which might not be halted but enforced in the future when more extreme weathers coincide with enhanced human activities.
Download or read book Biology Ecology and Management of Aquatic Plants written by Joseph Caffrey and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical and physical, and biological and biomanipulation. This series of papers from over 20 different countries was generated from the tenth in the highly successful series of European Weed Research Society symposia on aquatic plant management, this being the tenth. It provides a valuable insight into the complexities involved in managing aquatic systems, discusses state-of-the-art control techniques and deals with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.

This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
Download or read book Aquatic Plant Book written by Christopher D. K. Cook and published by . This book was released on 1996 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The book is a comprehensive guide to the aquatic plants of the world. It describes and illustrates 407 genera; including all ferns and flowering plants that are likely to be found in or floating on permanent or semi-permanent, fresh or salt water anywhere in the world. Care has been taken to describe juvenile and vegetative features which are often ignored in floristic literature but are so important for the identification of aquatics particularly as many species have short-lived or insignificant flowers that are easily overlooked or some species rarely develop flowers at all. The identification keys are based, when possible, on easily seen vegetative features. This book is also a reference work: for each genus information on distribution (native and introduced ranges), like forms, ecology, pollination mechanisms, disseminules and their dispersal mechanisms, uses, economic importance, and references to the literature is given." "It is hoped that this book will be of use not only to botanists and zoologists but also to all people concerned with aquatic ecosystems (natural or man-made) whether they be managers, engineers, weed controllers or conservation officers. Gardeners and aquarists should also find much useful information."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved

Download or read book Handbook of Plant Science 2 Volume Set written by Keith Roberts and published by John Wiley & Sons. This book was released on 2007-12-10 with total page 1697 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Science, like the biological sciences in general, has undergone seismic shifts in the last thirty or so years. Of course science is always changing and metamorphosing, but these shifts have meant that modern plant science has moved away from its previous more agricultural and botanical context, to become a core biological discipline in its own right. However the sheer amount of information that is accumulating about plant science, and the difficulty of grasping it all, understanding it and evaluating it intelligently, has never been harder for the new generation of plant scientists or, for that matter, established scientists. And that is precisely why this Handbook of Plant Science has been put together. Discover modern, molecular plant sciences as they link traditional disciplines! Derived from the acclaimed Encyclopedia of Life Sciences! Thorough reference of up-to-the minute, reliable, self-contained, peer-reviewed articles – cross-referenced throughout! Contains 255 articles and 48 full-colour pages, written by top scientists in each field! The Handbook of Plant Science is an authoritative source of up-to-date, practical information for all teachers, students and researchers working in the field of plant science, botany, plant biotechnology, agriculture and horticulture.

Download or read book The Status and Distribution of Freshwater Biodiversity in Central Africa written by E. G. E. Brooks and published by IUCN. This book was released on 2011 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main reasons cited for inadequate representation of biodiversity in the development processes is a lack of readily available information on inland water taxa. In response to this need for basic for information on species, the IUCN Species Programme conducted a regional assessment of the status and distribution of 2,261 taxa of freshwater fishes, molluscs, odonates, crabs and selected families of aquatic plants from throughout central Africa. This study is based on the collation and analysis of existing information, and the knowledge of regional experts.
