R1,680 Discovery Miles 16 800 Ships in 12 - 19 working days

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.

R4,944 Discovery Miles 49 440 Ships in 12 - 19 working days

Combining background knowledge and practical tools, Handbook of Inland Aquatic Ecosystem Management gives you an overview of how to manage inland waters in a holistic manner. It examines the problems that threaten aquatic inland water ecosystems and presents a set of toolboxes for solving them. The book focuses on lakes, reservoirs, ponds, rivers, wetlands, lagoons, and estuaries, including the predominant freshwater ecosystems as well as saline and brackish ecosystems. Understand Ecosystem Properties and Ecological Processes The book consists of two parts. The first part reviews the basic scientific knowledge needed in the environmental and ecological management of aquatic ecosystems, from limnology and ecology of inland water ecosystems to environmental physics and chemistry. It emphasizes the interacting processes that characterize all inland aquatic ecosystems and explains the scientific considerations behind the conservation principles and their applications. Define the Problems and Quantify Their Sources The second part of the book presents toolboxes that you can apply to achieve more holistic environmental and ecological management. After an overview of the environmental problems of inland aquatic ecosystems and their sources, the book examines toolboxes to help you identify the problem, namely mass balances, ecological indicators, and ecological models. It also discusses toolboxes that can be used to find an environmental management solution to the problem: environmental technology, cleaner technology, and ecotechnology. Integrate Science and Practical Toolboxes to Manage Inland Waters More Effectively This book shows you how to integrate biology, ecology, limnology, and chemistry with the toolboxes in an up-to-date, multidisciplinary approach to environmental management. It provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems threatening inland aquatic ecosystems.

Oar Feet and Opal Teeth - About Copepods and Copepodologists (Hardcover): Charles B. Miller Oar Feet and Opal Teeth - About Copepods and Copepodologists (Hardcover)
Charles B. Miller
R2,960 Discovery Miles 29 600 Ships in 12 - 19 working days

Oar Feet and Opal Teeth is about free-living copepods and the copepodologists who study them. Copepods are a subclass of the arthropod class Crustacea. They act as dominant herbivores and small predators in the planktonic ecosystems of oceans, estuaries, and lakes. Copepods are likely the largest assemblage of complex animals on earth. These strikingly beautiful small crustaceans are of wide ecological significance and as complex and precisely adapted as insects. Yet few biologists and others interested in animals are familiar with them. In Oar Feet and Opal Teeth, Charles B. Miller introduces these small crustaceans and the scientists devoting their careers to revealing their biology. In twenty-one chapters, Miller details the defining features and general biology of copepods. They typically have four or five pairs of oar-like feet to drive escape jumps. Teeth on mandible extensions are formed with siliceous minerals akin to opal. The first two chapters of the book closely examine the oar feet and mouth parts. Subsequent chapters describe internal anatomy, taxonomy, and many aspects of copepod natural history. Recent evolutionary insights about them are reviewed; those are based on molecular genetics and reach back to the Cambrian explosion. Oar Feet and Opal Teeth includes over twenty biographical sketches of copepodologists from the mid-twentieth century to the present. Among them, Russell Hopcroft, a premier photographer of plankton, has full-color copepod images featured throughout the book. Jeannette Yen learned how Euchaeta marina detects prey and studies how ready-for-mating copepods find each other. Shinichi Uye of Hiroshima University studied the production by copepods of resting eggs and their delayed development. Grace Wyngaard is studying the special embryonic cell-divisions of some lake copepods for eliminating "junk DNA." Miller based most of the profiles featured in the book on personal interviews he conducted.

As in the terrestrial environment, most data collection from freshwater habitats to date falls into the survey, surveillance or research categories. The critical difference between these exercises and a monitoring project is that a monitoring project will clearly identify when we need to make a management response. A Model for Conservation Management and Monitoring Monitoring (as defined by Hellawell) is essentially a tool of practical conservation management, and Fig. 1.1 shows a simple, but effective, model for nature conser- tion management and monitoring. The need for clear decision-making is implicit in this model. First we must decide what would represent a favourable state for the key habitat or species, and then we must decide when to intervene if the state is (or becomes) unfavourable. A third, often overlooked, but equally important, decision concerns when we would consider the habitat or species to have recovered; this is unlikely to be the same point that we became concerned about it. This decision not only has resource imp- cations, it can also have major implications for other habitats and species (prey species are an obvious example). All of these decisions are essential to the devel- ment of an efficient and effective monitoring project.

R4,355 Discovery Miles 43 550 Ships in 10 - 15 working days

Lake Issyk-Kul is a closed lake located in the Tien Shan mountain belt of the Republic of Kyrgyzstan. It is the world's fifth deepest lake (668 m) and the second largest high altitude lake in the world (1607 m above sea level). The lake is affected by several environmental threats of both anthropogenic and natural origin: decline of the lake level resulting in progressively increasing salinity, incomplete vertical water exchange, and risk of contamination by past and present industrial activity.
Although the lake has been intensively studied, the information is only available in unpublished reports or local scientific journals. This book presents for the first time to an international audience the main physical, chemical, biological and geological characteristics of the lake, the fruits of many years of observations, complemented by recent results of international projects. Case studies of similar problems in other parts of the world are presented, together with ethical aspects of the environmental protection of the lake.

R3,881 Discovery Miles 38 810 Ships in 12 - 19 working days

Lakes and rivers of the tropics are rich with variety and human relevance, yet do not figure prominently in surveys of general freshwater biology and limnology. The fruits of their scientific exploration are largely embodied in regional and specialist descriptions and analyses. In this book the authors take a generalized view, on a world-wide scale, that is dynamic and quantitative in outlook. They set out to integrate events and processes under tropical conditions, not only geographically but also within a continuum of physics, chemistry and biology, so providing a foundation that will be of value to all who study and work with tropical inland waters.

R1,507 Discovery Miles 15 070 Ships in 10 - 15 working days

In the decade since the first edition of this book was published advances have been made in our knowledge of the fresh waters of the world, espe cially in understanding many of the processes involved in their functioning as systems and in countering the problems created by human activities. New problems too, many of an international nature, have loomed during this period-of which global warming and the acidification of fresh waters in many parts of the world are notable examples. In addition, much has now been published concerning the aquatic flora, fauna and ecology of previously poorly known geographic areas, notably Australasia. The second edition of this book is a revision which updates the text in the light of recent advances in our knowledge of freshwater biology. Inevitably, in an elementary volume such as this, the treatment of many of the basic principles and processes remains the same. However, several new sections are included covering a range of topics such as acid deposition and the acidification process, bacterial decomposition and aquaculture. The book includes many new references and suggestions for up-to-date reading in particular topics. The objective of the second edition remains the same as that of the first. It is intended as a basic introduction to the major aspects of freshwater biology at a level suitable for undergraduates. It should also prove useful, as apparently did the first edition, to professional workers in related fields, e.g. water engineers and chemists, aquaculturists and planners."

R5,233 Discovery Miles 52 330 Ships in 12 - 19 working days

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives.

This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN.

As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms.

The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.

R2,145 Discovery Miles 21 450 Ships in 12 - 19 working days

This study, conducted in Kenya, gives the first insight into the performance of a constructed treatment wetland receiving pulp and paper mill wastewater in the tropics.

The wetland effectively removed organic matter, suspended solids, phenols and nutrients. BOD and phenols reduction rates are reported for the first time. Design parameters and guidelines for the set-up and maintenance of a full-scale wetland are recommended. The study concludes that integrating a full-scale wetland, as a tertiary stage with the existing treatment ponds would significantly improve the quality of water in River Nzoia downstream of the effluent discharge.

This is a valuable resource book for scientists, managers and students in the field of wetland ecology, water and environmental management.

R1,397 Discovery Miles 13 970 Ships in 9 - 17 working days

The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.

R5,449 Discovery Miles 54 490 Ships in 12 - 19 working days

Global wetlands exhibit significant differences in both hydrology and species composition and range from moss-dominated arctic peatlands to seasonally-flooded tropical floodplains. They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological features of wetland habitats, with an emphasis on wetland plants and animals and their adaptations. It also describes the functional features of wetlands - primary production, litter decomposition, food webs, and nutrient cycling - and their significance locally and globally. The future of wetlands is examined, including the potential threats of global climate change and invasive species, as well as their restoration and creation. This new edition maintains the structure and style of the first, but is fully updated throughout with new chapters on invasive species, restoration/creation, global climate change, and the value of wetlands.

R4,846 Discovery Miles 48 460 Ships in 12 - 19 working days

Snow and ice environments support significant biological activity, yet the biological importance of some of these habitats, such as glaciers, has only recently gained appreciation. Collectively, these ecosystems form a significant part of the cryosphere, most of which is situated at high latitudes. These ice environments are important sentinels of climate change since the polar regions are presently undergoing the highest rates of climate warming, resulting in very marked changes in the extent of ice caps, glaciers, and the sea ice. Glacial systems are also regarded as an analogue for astrobiology, particularly for Mars and the moons of Jupiter (e.g. Europa), and one of the justifications for research in this area is its potential value in astrobiology. This timely and accessible volume draws together the current knowledge on life in snow and ice environments. It describes these often complex and often productive ecosystems, their physical and chemical conditions, and the nature and activity of the organisms that have colonised them. The cryosphere is the domain of extremophiles, organisms able to adapt to the physiological and biochemical challenges of harsh cold conditions where liquid water may only be present for relatively short periods each year. The majority of extremophiles in ice and snow are microorganisms. The Ecology of Snow and Ice Environments is intended for the non-specialist, enabling environmental scientists to understand the biological functioning of extreme cold environments and for biologists to gain knowledge of the nature of the cryosphere.
