Download or read book The Comparative Roles of Suspension Feeders in Ecosystems written by Richard F. Dame and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals are a major link between the water column (pelagic) and the bottom (benthic) habitats in most shallow systems. This coupling is dominated by active processes such as suspension-feeding in which the organism actively uses energy to pump water that is then filtered to remove suspended particles that are consumed while undigested remains are deposited on the bottom. As a result of this feeding on and metabolism of particles, the animals excrete dissolved inorganic and organic waste back into the water column, and thus, become major components in the cycling and feedback of essential elements. With relatively high weight specific filtration rates of 1— 10 liters/hour/gram dry tissue and a propensity to form large aggregated populations (beds, reefs, schools and swarms), these organisms can play an important role in regulating water column processes Although estuarine bivalve molluscs such as oysters and mussels dominate the suspension-feeder literature, other groups including plankton and nekton that are found in estuarine as well as other aquatic systems are also potentially important removers of suspended particles. Thus, a significant part of the NATO Advanced Research Workshop focused on suspension-feeders as controllers of plankton abundance, biomass and diversity, system metabolism, nutrient cycling and scale dependency. Systems dominated by suspension-feeders are typically impacted by human activities including recreation, aquaculture, human and industrial pollution, and bilge water from shipping. Suspension-feeders are often impacted by fisheries and over-exploitation. These impacts commonly result in changes in ecosystem structure either through the food chain concentration of harmful substances or diseases, the introduction of alien species of suspension-feeders, or the instability of suspension-feeders systems through species displacement or phase shifts in the dominance between different suspension-feeding components such as nekton or zooplankton. These issues were addressed near the close of the workshop along with conclusions and syntheses developed by the working groups.
Download or read book Freshwater Aquariums written by David Alderton and published by Fox Chapel Publishing. This book was released on 2003-02-01 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: For beginning aquatic fancier looking to start out right with fish, Freshwater Aquariums by David Alderton is the ideal primer. A vertebrate that breathe primarily by means of gills and swim by means of fins is the author’s lead-in to the first chapter called “What are Fish?” Alderton builds the reader’s confidence by providing solid information about what fish are anatomically speaking, how they evolved, how they breathe, how they move, where they live, and how they behave. The new fancier’s aquarium begins in chapter two with instructions on setting up the tank, including selecting the right size, figuring out how many fish, setting the tank, equipment, substrate, heating, lighting, filtrations, plants, water chemistry, assembly, and more. Choosing the freshwater fishes that appeal to the reader is the subject of “Introducing the Categories of Fish,” which schools readers in seven categories: Cyprinids (e.g., goldfish, minnows, and barbs), Characins (e.g., tetras), Cichlids (e.g., oscars, angelfish, and discus), Anabantoids (gouramis, bettas/Siamese fighting fish, and paradise fish), Toothcarps (guppies, swordtails, platies, black mollies, and killifish), Catfish, and others (loaches and Chinese algae eaters). The purchasing, maintenance, and feeding of fish are described in considerable details, and the author gives a basic overview of breeding and keeping fish healthy as well. Resources, glossary, and index conclude the book.
Download or read book Thorp and Covich s Freshwater Invertebrates written by James H. Thorp and published by Elsevier. This book was released on 2014-09-06 with total page 1149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels
Download or read book Freshwater Microplastics written by Martin Wagner and published by Springer. This book was released on 2017-11-21 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.
Download or read book Invertebrates in Freshwater Wetlands written by Darold Batzer and published by Springer. This book was released on 2016-02-05 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, a wide variety of new chemicals have continued to be developed as a result of industrial development and associated anthropogenic activities. The microbial contaminants in the environment, more precisely, antibiotic-resistant genes/bacteria produced as a result of mutation due to antibacterial drugs, are also considered emerging contaminants and specifically called emerging microbial contaminants such as sapoviruses, Waddlia chondrophila and Streptococcus parauberis. Additionally, pharmaceuticals and personal care products are a diverse group of compounds that include ibuprofen, diclofenac, triclosan, antibiotics, anti-inflammatory agents, steroidal hormones and active ingredients in soaps, detergents and perfumes which could find their way into food materials, are tagged as emerging contaminants. Given this, Emerging Contaminants in Food and Food Products discusses issues around the emerging contaminants in food and food products. Different types of contaminants, such as biological, chemical, organic, inorganic and microbial contaminants in foods, ways of detecting them and regulations surrounding global food safety, are all covered. Key features: Discusses all the categories of contaminants in food and food products. Biological, chemical, organic, inorganic and microbial contaminants. Provides full information on emerging food contaminants, their effect on human and animal health, and how it affects global food security and emerging technological applications in solving this global problem. Gives detection and prevention strategies and guideline policies on emerging contaminants of foods. Brings into account global perspectives on food contaminants and health implications. This volume will serve as an information hub of emerging contaminants for scientists/researchers and professionals globally. This book is a good collection of independent chapters, which presents full insights into the study of emerging contamination in food and the effects of these contaminants in humans and animals.

Download or read book The Role of Food Agriculture Forestry and Fisheries in Human Nutrition Volume II written by Victor R. Squires and published by EOLSS Publications. This book was released on 2011-11-15 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Role of Food, Agriculture, Forestry and Fisheries in Human Nutrition is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Human health and wellbeing depend strongly on production, quality, and availability of food. Agriculture, or cultivation of the soil, harvesting crops, and raising livestock, which are the main sources of food, has no single origin. At different times and in numerous places, many plants and animals have been domesticated to provide food for humankind. Fishing, like farming, is a form of primary food production. Through food gathering, primitive humans first obtained fish and other aquatic products in the shallow waters of lakes and along the seashore, in areas with ebb tides, and in small streams. The breadth and complexity of the subject matter presented here is vast. This volume traces the extraordinary history of human colonization of the habitable world and is a chronicle of humankind’s early communion with the underlying realities of the earth’s physical environment, the eventual destruction of this harmonious relationship, and efforts to repair the damage. To make it easier for the reader the volume is divided into 7 sections Food and agriculture and the use of natural resources examines the relationship between food production and the resource base and demonstrate how humans have adapted and exploited Nature to feed the burgeoning populations of humans and their domestic animals. History of forestry from ancient times to the present day is analyzed and shows the linkage between forest clearance for agriculture and the rise of human populations, and current global environmental issues. History of Fishing is a saga explained that spans the full range from traditional fishing for subsistence through to the evolution of modern factory fishing fleets Impact of global change on agriculture outlines the impact of climate change, human demographic trends and the sustainability issues that arise. Economics and policy of food production analyzes the global trade in foodstuffs and the regional specializations and land use complexities. Fundamentals of human health and nutrition explains the complexities of providing a balanced and safe diet for humans throughout their life cycle from birth to old age. It explores some of the linkages between human health and the quality and quantity of food provided. Human nutrition: an overview provides, a wide ranging summary of the issues and imperatives associated with providing humans with food of a quality and standard that will ensure healthy lives. In the history of human development from the time of the earliest agricultural activities humans have cleared the natural forests and woodlands to obtain building materials and fuel wood, and to provide lands for domestic animals and crops. It is this aspect that is the main focus of the volume. The authors in this volume have analyzed and reviewed the interactions between the utilization of natural resources and human nutrition. Much attention focuses on the specific contribution by agriculture (including livestock husbandry), forestry and fisheries in meeting human needs. This synoptic overview assesses the pattern of past change in the relationship between humans and the resource base on which their lives depend. Lessons learned, or still to be learned, are teased out and elaborated. The vast breadth of the subject matter covered in this volume has meant that the work has benefited from the input of many individual contributors from vastly different parts of the globe. I am grateful to the contributors and reviewers for their time and effort and the exchange of ideas and the learning experience that I obtained by working with such a diverse and learned group. We all owe a debt of gratitude to the vast "invisible college" of colleagues whose publications that have shed light on some of the most pertinent problems facing humankind today. These four 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 Fundamentals of Aquatic Ecology written by R. S. K. Barnes and published by John Wiley & Sons. This book was released on 2009-07-21 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Aquatic Ecology is a completely updated and revised edition of the earlier work, Fundamentals of Aquatic Ecosystems. The new edition has been re-titled to reflect the fact that the authors found that, from the modification exercise, a completely different and new book emerged. The new edition concentrates heavily of the fundamental features common to all aquatic systems, both marine and freshwater. This unique synthesis allows for the discussion of ecological processes comparatively, across environments. A general introduction is followed by discussion of various 'types' of aquatic ecosystems - open waters, coastal zones, benthos, and the aquatic ecosystem as a whole. This is followed by an important new chapter on aquatic ecosystems and global ecology. Later chapters consider the individuals and communities in aquatic ecosystems. A totally re-written and rejuvenated edition of an established student text. Synthesizes both marine and freshwater ecology. Covers both ecosystem ecology and population biology. In depth consideration of man's impact on the aquatic environment.
