Book excerpt: Wigeongrass (Ruppia maritima L.) is a submersed macrophyte of nearly cosmopolitan distribution and worldwide importance as a waterfowl food. Unfortunately, the plant no longer inhabits vast areas disturbed by human activities. Taxonomic status of the plant is uncertain, especially in North America. In mild climates, in habitats subject to environmental extremes, the plant behaves as an annual (vegetation perishes), or as a perennial in deeper, more stable habitats (some vegetative parts grow year round). Drupelets (seeds) provide a mechanism for wigeongrass to survive periods of drought and excessive water salinity. These sexual propagules can be washed ashore or carried by birds or fish for long distances. Wigeongrass mostly occurs in temporarily to permanently flooded mesohaline-hyperhaline estuarine wetlands, but it also occurs inland in fresh to hypersaline palustrine and lacustrine wetlands. Most populations inhabit warm, relatively unpolluted, and well lit waters

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.

Download or read book Impaired Wetlands in a Damaged Landscape written by Kevin P. Timoney and published by Springer. This book was released on 2015-07-01 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a scientific monograph that examines the flora and vegetation of natural mineral wetlands in comparison to mineral wetlands affected by bitumen exploitation. The work is of broad relevance because (a) wetland loss and degradation is a global problem; (b) the continued global increase in fossil fuel exploitation is resulting in widespread damage; and (c) bitumen (tar sands, oil sands) exploitation is a rapidly growing and destructive set of activities. The core of the work is a meta-analysis of 417 vegetation plots. Analyses of change over time and chemical and physical attributes of water and soil are presented for the subset of plots with sufficient data. The purpose of the work is to demonstrate that: (1) There are marked differences between natural and industrially-affected wetlands. (2) Industrially-affected mineral wetlands differ from natural wetlands in their vegetation assemblages, their depressed vegetation and species diversity, and their abundance of exotic weeds. (3) Successful post-bitumen mining wetland reclamation has not been accomplished and may not be attainable within the foreseeable future given the ecological and physical conditions of the industrial wetlands, current reclamation practices, and lax regulatory standards. In regard to government policy and industrial practices, it finds that they are responsible for reclamation failure on a grand scale.

Download or read book Large Asian Lakes in a Changing World written by Steffen Mischke and published by Springer Nature. This book was released on 2020-05-11 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describing the natural state of eight important lakes in Asia and the human impact on these lake ecosystems, this book offers a valuable reference guide. Over the past several decades the Aral Sea, Dead Sea, Lake Balkhash and other major lakes in Asia have undergone significant changes with regard to their size, water level, chemical composition, and flora and fauna. Most of these changes resulted from the loss of water from tributaries (now used for irrigation farming) or increasing consumption in local industries and households. However, significant human impacts may have begun as early as 2000 years ago. In addition to the three lakes mentioned above, Lake Sevan (Armenia), the Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan), Lake Issyk-Kul (Kyrgyzstan), and Lake Lop Nur (China) are discussed as the most prominent examples of changing lake ecosystems. In contrast, an example of an almost pristine lake ecosystem is included with the report on Lake Uvs Nuur (Mongolia). For each lake, the book summarizes its origin and early geological history, and reconstructs its natural state and variability on the basis of proxy records from drilled or exposed lake sediments that have accumulated since the last ice age. The frequently observed reductions in lake level and size during most recent decades led often to significant environmental impacts in the respective lake catchments including vegetation deterioration, soil erosion and badland formation, soil salinization or the formation of sinkholes.

Download or read book Oceanography and Marine Biology written by R.N. Hughes and published by CRC Press. This book was released on 2016-11-25 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever-increasing interest in oceanography and marine biology and their relevance to global environmental issues create a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its founding by the late Harold Barnes more than 50 years ago. Its objectives are to consider, annually, the basic areas of marine research, returning to them when appropriate in future volumes; to deal with subjects of special and topical importance; and to add new subjects as they arise. The favourable reception and complimentary reviews accorded to all the volumes shows that the series is fulfilling a very real need. Volume 54 follows closely the objectives and style of the earlier volumes, continuing to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments. It is consistently among the highest ranking series in terms of impact factor in the marine biology category of the citation indices compiled by the Institute for Scientific Information/Web of Science.
