Life in Ephemeral Waters

More than a natural history, this book explains the underlying forces that drive ecological change and movement in Australian wetlands.

An academically focused collection of papers highlighting the successes and challenges of a move from disaster to risk management in responding to drought. The book passes on the experiences gained from Australia’s trail-blazing new policy, introduced in 1992.

Freshwater life – the first illustrated field guide of its kind for the wider southern African region – describes a vast range of plant and animal groups in a single volume. A ground-breaking concept that encompasses diverse groups from the large and conspicuous vertebrates to the diverse microscopic taxa, the book facilitates identification and describes the ecology of more than 1,000 freshwater organisms. Species have been selected on the basis of how likely they are to be encountered, and each account is accompanied by photographs and a distribution map. A comprehensive introduction details the ecology and signifi cance of freshwater systems. This indispensible, easy-to-use guide will prove invaluable to outdoor enthusiasts, students and conservationists.

This book is an overview of freshwater invertebrates, and a useful identification guide for both academics and enthusiasts.

Australia is the world's driest inhabited continent. Water is our limiting resource. It might therefore be thought that our water resources would be the subject of the most intensive study. Certain aspects, it must be conceded, have received much attention, notably the availability of water in terms of actual quantity. The size of the surface water and the groundwater resource is well understood and indeed receives about as much study as can reasonably be expected in a country with as sparse a population and level of scientific manpower as ours. Although the importance of understanding the water resource in terms of quantity is widely accepted, what has not been generally appreciated is that for this resource to be 'available' to human society for all the different uses to which it is put, it is not sufficient that there exists within easy reach of the end users a certain total volume of water. For that water to fulfil its functions-for agriculture, industry, the home, recreation, biological conservation-it must be in a certain state: it must conform to certain chemical, physical and biological criteria, and what has not been sufficiently appreciated in Australian society is that the condition a water is in depends very much on the ecology of the waterbody in which it resides. There are waterbodies in the world, for example high-altitude glacial lakes, which are naturally so pristine that their water could be used for any purpose without treatment.

The interdisciplinary nature of limnology requires lucid and well-integrated coverage of biology, chemistry, physics, earth science, and resource management. Paul Weihe skillfully accomplishes this objective in his revision of Gerald Cole’s classic limnology text. This long-awaited revision introduces concepts in straightforward terms, replete with detailed examples, elegant illustrations, and up-to-date, well-researched documentation. Outstanding features of the fifth edition include: • A global outlook with examples from every continent • Discussions of the impact of environmental challenges (e.g., climate change, eutrophication, river regulation) with case studies of real-world examples • A chapter devoted to wetlands • A thorough examination of biogeochemistry, including recent anthropogenic alteration and a reconsidered understanding of stoichiometric relationships • Expanded treatment of hydrology, utilizing empirical approaches to discharge determination and effects of land-use changes • A reorganized presentation of biodiversity, explicitly correlating profiles of biota with community ecology and ecosystem function • Updated taxonomy with a description of the new metagenomic approach, nomenclature strictly adhering to the intergovernmental Integrated Taxonomic Information System

Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. Provides up-to-date reviews of research findings and management strategies using international examples Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach Reveals the relevance of this scientific understanding to managers and policymakers

Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.

This is the second volume on dormancy in aquatic organisms. The book is divided into three parts whereby the first part is devoted to several groups of aquatic organisms which are under-studied in terms of the dormancy’s role in the life cycle. The second part looks at the use of dormancy phenomena in science and potential human applications. Furthermore, part 3 comprises of examples of using modeling in relation to dormancy phenomenon and it opens with a theoretical analysis of studies of biological information, including seasonal information. This work can be used as a text book for students as well as a manual for science and practice purposes in ecology, aquaculture, nature protection and space researches with regards to creating ecological life supporting systems and discovering extraterrestrial life on other planets with harsh environmental conditions.

In "Life's Matrix", Philip Ball writes of water's origins, history, and unique physical character. His provocative exploration of water on other planets highlights the possibilities of life beyond Earth. It also examines the grim realities of depletion of natural resources and its effects on the availability of water in the 21st century. Illustrations.

Jan Bowers lives in the right place. A lover of nature and the outdoors, an avid hiker and backpacker, she is surrounded by mountain ridges, peaks, and canyons of almost every description. In this book, she invites us to come along and find out why some of these places are special, why some of them stay in her mind long after she has returned to the workaday world of the city. Readers have come to expect the best from this writer, termed "a rare talent. . . uncommonly good at the craft" by Wilderness magazine. Her new book is filled with creeks and meadows, tiny ferns and towering oaks, bears and butterflies and Red-tailed Hawks. We see gray clouds clogging the sky in a canyon, "wildly, almost tastelessly romantic, as full of clouds as a tea kettle with steam," and we startle a female grouse and her half-dozen fuzzy chicks "exploding from underfoot like billiard balls scattered with a cue stick." Faced with the prospect of moving to another place, Bowers finds herself thinking about the familiar world in new and unfamiliar ways. Through her eyes, too, we see how an interest in nature and the outdoors developed from early childhood and how simple curiosity has led her to the most surprising discoveries. At odd and unexpected moments, her work also seems to bring new insights into herself and her life as a writer, a wife, and a mother. These pages promise a new adventure at every turn in the trail. For sheer terror, there's a climb up the face of Baboquivari, for laughs, there's the great bagworm caper, and for some quiet truths, there are themes of gain and loss, of connection and reconcilliation. Crunching through winter snow or sweating under summer sun, we know we're in the hands of an experienced guide. And we know we couldn't ask for a better companion.

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
