Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book excerpt: Cave organisms are the ‘monsters’ of the underground world and studying them invariably raises interesting questions about the ways evolution has equipped them to survive in permanent darkness and low-energy environments. Undertaking ecological studies in caves and other subterranean habitats is not only challenging because they are difficult to access, but also because the domain is so different from what we know from the surface, with no plants at the base of food chains and with a nearly constant microclimate year-round. The research presented here answers key questions such as how a constant environment can produce the enormous biodiversity seen below ground, what adaptations and peculiarities allow subterranean organisms to thrive, and how they are affected by the constraints of their environment. This book is divided into six main parts, which address: the habitats of cave animals; their complex diversity; the environmental factors that support that diversity; individual case studies of cave ecosystems; and of the conservation challenges they face; all of which culminate in proposals for future research directions. Given its breadth of coverage, it offers an essential reference guide for graduate students and established researchers alike.

Available in PDF, EPUB and Kindle. Book excerpt: At the First International Symposium on Aquatic Oligochaete Biology in Sidney, B. C. , the suggestion was made to hold the second in Pallanza, on Lake Maggiore, at the C. N. R. -Istituto Italiano di Idrobiologia. At the same time it was decided that there should be a symposium every third year. The organization of the symposium was made considerably easier by the Senior Editor's having been in personal contact with several Russian colleagues (courtesy of a kind invitation from the U. S. S. R. Academy of Sciences), the 'Hamburg Group' and the Junior Editor. Correspondence with various students of Oligochaeta also furnished many useful suggestions. The Second International Symposium on Aquatic Oligochaete Biology was therefore held in Pallanza in late September 1982 and was attended by 53 scientists from 16 countries in Europe, North America, Asia and Australia. No review papers were formally invited as this had already been done at the first symposium: all the papers were accordingly allotted the same time for oral presentation. These proceedings contain all papers Hrabe and Slepukhina, which were given in absentia, as it presented at the symposium, including those by was impossible for the authors to join the group. The main topics were taxonomy and evolution of Oligo chaeta, life-cyle and population studies, the role of Oligo chaeta in assessing water pollution, physiolog ical studies, community and distribution studies. Special taxonomic workshops took place in the evenings.

Available in PDF, EPUB and Kindle. Book excerpt: As pressures on Australia's inland waters intensify from population growth, expanding resource development and climate change, there is an urgent need to manage and protect these special areas. Understanding their ecology underpins their wise management and conservation. Australian Freshwater Ecology vividly describes the physical, chemical and biological features of wetlands, lakes, streams, rivers and groundwaters in Australia. It presents the principles of aquatic ecology linked to practical management and conservation, and explains the causes, mechanisms, effects and management of serious environmental problems such as altered water regimes, eutrophication, salinization, acidification and sedimentation of inland waters. Key features: contributions from a diverse, highly qualified team of aquatic ecologists whose expertise spans the ecology and management of standing and running waters in Australia sections covering groundwaters, biodiversity, temporary and tropical waters, climate change, invasive species and freshwater conservation numerous Australian case-studies and guest 'text-boxes' showing management in practice concise descriptions of ecological processes and conceptual models illustrated with original, high- quality diagrams and photographs Readable and logically structured, this text supports undergraduate and postgraduate courses in aquatic ecology and management. It is a valuable reference for consultants, restoration ecologists, water resource managers, science teachers, and other professionals with an interest in the ecology of surface and groundwaters.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been a central concern over recent years, with visible and highly publicized consequences such as melting Arctic ice and mountain glaciers, rising sea levels, and the submersion of low-lying coastal areas during mid-latitude and tropical cyclones. This book presents a review of the spatial impacts of contemporary climate change, with a focus on a systematic, multi-scalar approach. Beyond the facts – rises in temperature, changes in the spatial distribution of precipitation, melting of the marine and terrestrial cryosphere, changes in hydrological regimes at high and medium latitudes, etc. – it also analyzes the geopolitical consequences in the Arctic and Central Asia, changes to Mediterranean culture and to viticulture on a global scale, as well as impacts on the distribution of life, for example, in the Amazon rainforest, in large biomes on a global scale, and for birds.

Available in PDF, EPUB and Kindle. Book excerpt: Shallow subterranean habitats (SSHs) are areas of habitable space that are less than 10 m in depth from the surface. These range from large areas such as shallow caves and lava tubes, to tiny areas such as cracks in ceilings, or spaces in soil. Whilst being very different in many ways, they are often bound together by shared characteristics of the habitats and their faunas, and their study can help us to understand subterranean habitats in general. This book concentrates on the more typical SSHs of intermediate size (seepage springs, spaces between rocks, cracks in lava etc.), describing the habitats, their fauna, and the ecological and evolutionary questions posed. Similarities and differences between the habitats are considered and discussed in a broader ecological and evolutionary context. The book is mainly aimed at students and researchers in the field of subterranean biology, but will also be of interest to a wider range of ecologists, evolutionary biologists, freshwater biologists, and conservationists. There will also be an audience of environmental professionals.

Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the latest developments concerning the analysis, fate, behaviour and toxicity of pyrethroid insecticides. Over the last few decades, pyrethroid insecticides have increasingly replaced organochlorine pesticides due to their relatively lower mammalian toxicity, selective insecticide activity and lower environmental persistence. They represent 25% of global sales of insecticides, and are considered to be “safe” since they are converted to non-toxic metabolites by oxidative metabolism in fish and by hydrolysis in mammals. However, recent studies have demonstrated their environmental ubiquity, their bioaccumulation and their toxicity in various aquatic and terrestrial organisms, and even in humans. Featuring contributions by leading experts, the book discusses the physico-chemical properties and uses of pyrethroid insecticides; the latest chemical analytical methods; their occurrence in the environment, biota and food; and their isomeric and enantiomeric behaviour. It particularly highlights the toxicological effects and human exposure to pyrethroid insecticides, and also offers insights into the effects of the salmon industry on the marine environment with a case study of sea lice treatment using pyrethroids. This comprehensive book is a valuable source of information for environmental scientists, policymakers and producers interested in issues related to pyrethroid insecticides.

Available in PDF, EPUB and Kindle. Book excerpt: While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.

This book was released on 2019-04-01 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this widely cited textbook continues to provide a concise but comprehensive introduction to cave and subterranean biology, describing this fascinating habitat and its biodiversity. It covers a range of biological processes including ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation. The authors draw on a global range of examples and case studies from both caves and non-cave subterranean habitats. One of the barriers to the study of subterranean biology has been the extraordinarily large number of specialized terms used by researchers; the authors explain these terms clearly and minimize the number that they use. This new edition retains the same 10 chapter structure of the original, but the content has been thoroughly revised and updated throughout to reflect the huge increase in publications concerning subterranean biology over the last decade.

Book excerpt: The Ecological Bases for Lake and Reservoir Management provides a state-of-the-art review of the range of ecologically-based techniques necessary for the holistic management of lakes and their catchments. Most of the methods, case studies and national policies reviewed are directed towards management of the largest problem - eutrophication - with the emphasis on the multiple-scale approach needed for successful management and restoration. Case studies come from the USA and ten European countries, and range from single lakes through to lake districts and national inventories. Several essays precede the practical chapters with thought-provoking comments on the political, social and economic climate of water management.

Available in PDF, EPUB and Kindle. Book excerpt: This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
