Available in PDF, EPUB and Kindle. Book excerpt: Aquatic ecosystems have formed the focus of several UNESCO research projects because of the impact on them of human activities such as intensification of agricultural activity, erosion and sedimentation due to irrigation projects, groundwater pollution and eutrophication. Interfaces, or ecotones, between terrestrial and aquatic ecosystems were found to have an essential role in the movement of water and materials throughout the landscape. Ecotones are zones where ecological processes are more intense and resources more diversified. They are also zones which react quickly to human influences and changes of environmental variables. This volume summarises the results presented at an international conference dedicated to the study of groundwater/surface water ecotones, with contributors of international scientific reputation representing the multidisciplinary viewpoints of hydrologists, biologists and ecologists. It addresses areas of active research in hydrology and biology, and is aimed towards researchers, water resource project managers and policy makers.
Download or read book Nutrient Dynamics and Retention in Land Water Ecotones of Lowland Temperate Lakes and Rivers written by A. Hillbricht-Ilkowska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.

Download or read book Fresh Surface Water Volume II written by James C.I. Dooge and published by EOLSS Publications. This book was released on 2009-08-25 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fresh Surface Water theme is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The occurrence of surface water in abundance is unique to planet Earth among the inner or terrestrial planets. This is only one of the environmental consequences of the anomalous properties of water. Water has been central to human life and human thought throughout history. The availability of fresh surface water varies between continents, between regions within any given continent, between countries in a given region, and between catchments in a given country.Five key topics have been identified under the theme of Fresh Surface Water. These are: Origin, Resources and Distribution of Rivers and Streams; Characteristics of River Systems; Transport Processes in River Systems; River Ecosystems; The Uses of River Water and Impacts, which are then expanded into multiple subtopics, each as a chapter. These three volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, Managers, and Decision makers and NGOs

Download or read book Ecophysiology and Food Web Dynamics of Spring Ecotone Communities in the Edwards Aquifer USA written by Parvathi Rajan Nair and published by . This book was released on 2019 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring orifices serve as ecotones between groundwater and surface water habitats. It is thought that organisms living in physicochemically stable spring ecotones should exhibit small tolerance ranges; however, previous experiments examining this prediction are equivocal. I examined this hypothesis by investigating effects of elevated temperature and decreased dissolved oxygen on several riffle beetle species (Coleoptera: Elmidae), including two ecotone specialists. Results indicate that ecotone-associated species exhibit stenothermal tolerance profiles when compared to surface species. I also examined resource use in invertebrate communities at two spring ecotones using stable isotopes of carbon (d13C) and nitrogen (d15N) and amino acid-specific stable isotopes (d13CAA). Results indicate that spring ecotones contain trophically complex communities with substantial niche partitioning among species. I finally examined the hypothesis that subterranean organisms in systems with ample energy resources (such as guano caves or spring ecotones) may not exhibit reduced metabolic rates. I assessed metabolic and biochemical responses of a subterranean amphipod (Stygobromus pecki) that inhabits spring ecotones and compared these responses to their epigean relative. Results indicate that S. pecki, despite its occupation of relatively resource rich spring opening ecotones, still exhibit lower metabolic rates relative to their epigean relative. Cumulatively, this body of research provides new and critical information on the ecology and evolution of spring ecotone communities, which are among the least studied and poorly understood aquatic ecosystems.
Download or read book Groundwater and Surface Water Pollution written by David H.F. Liu and published by Routledge. This book was released on 2019-01-22 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater and Surface Water Pollution contains almost all the technical know-how required to clean up our water supply. It provides a survey of up-to-date technologies for remediation, as well as a step-by-step guide to pollution assessment for both ground and surface waters. The book defines groundwater, aquifers and surface water and discusses the physical properties of soils, liquids, vadose zones and aquifers. It emphasizes controlling nonpoint source pollution, best management practices, and an integrated management approach. The editors cover not only engineering but also legal, medical, agricultural, meteorological, biological and other fields of study. They reach beyond the simplistic hydrological cycles usually addressed to the complexities encountered by rapidly-changing land-use patterns. In addition to focusing on causes, effects, and remedies, Groundwater and Surface Water Pollution stresses reuse, recycling, and recovery of resources. Nature does not cause pollution. Through total recycling, we can, like nature, make resources out of wastes. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.

Download or read book Streams and Ground Waters written by Jeremy B. Jones and published by Elsevier. This book was released on 1999-12-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Streams around the world flow toward the sea in floodplains. All along this transit, there is exchange of water between the stream itself and the surrounding sediments which form the floodplain. Many chemical, biological, and geological processes occur when water moves back and forth between streams and these flood plain sediments. Streams and Groundwaters focuses on the consequences of water flow between streams, their underlying sediments, and surrounding landscapes. Certain to appeal to anyone interested in stream ecology, the management of stream ecosystems, or landscape ecology, this volume should become a oft-opened reference.
