Book Description
Zooplankton are of key importance in the structure and functioning of aquatic food webs. They contribute to a large part of the functional and structural biodiversity of predator and prey plankton communities. Promptly responding to long-term and seasonal changes in the physical and chemical environment, they are sensitive indicators of patterns and mechanisms of impact drivers, both natural and human induced. In this volume, we aim to present evidence for both long-term and seasonal changes in zooplankton community structure and dynamics, investigating different approaches from population dynamics to advanced molecular techniques and reconstructing past communities from subfossil remains in lake sediments.

Book Description
This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.

Book Description
Takes the hallmarks of metapopulation theory to the next level by considering a group of communities, each of which may contain numerous populations, connected by species interactions within communities and the movement of individuals between communities. This book seeks to understand how communities work in fragmented landscapes.

Book Description
This substantially revised and update edition of a work first published in 1980 in the USA and deals with the ecological effects of water pollution. It is the result of twenty years of teaching the subject and will be essential reading for all those interested in water quality.

Book Description
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.

Book Description
The Middle Paraná river is one of the largest in the world. Exceptionally rich in fauna and flora, it provides researchers with a glimpse into an ecosystem yet undisturbed by human civilization. This fascinating book covers all the key aspects of the Paraná’s fluvial limnology and ecology, arranged in discrete and easily navigable sections. First, the physical and chemical environment is explained, then the river’s plant life, followed by its invertebrate life, and finally the vertebrates that inhabit the river.

Book Description
In North America, concepts of Historical Range of Variability are being employed in land-management planning for properties of private organizations and multiple government agencies. The National Park Service, U.S. Fish & Wildlife Service, Bureau of Land Management, U.S. Forest Service, and The Nature Conservancy all include elements of historical ecology in their planning processes. Similar approaches are part of land management and conservation in Europe and Australia. Each of these user groups must struggle with the added complication of rapid climate change, rapid land-use change, and technical issues in order to employ historical ecology effectively. Historical Environmental Variation in Conservation and Natural Resource Management explores the utility of historical ecology in a management and conservation context and the development of concepts related to understanding future ranges of variability. It provides guidance and insights to all those entrusted with managing and conserving natural resources: land-use planners, ecologists, fire scientists, natural resource policy makers, conservation biologists, refuge and preserve managers, and field practitioners. The book will be particularly timely as science-based management is once again emphasized in United States federal land management and as an understanding of the potential effects of climate change becomes more widespread among resource managers.

Book Description
This important new book by Colin Reynolds covers the adaptations, physiology and population dynamics of phytoplankton communities. It provides basic information on composition, morphology and physiology of the main phyletic groups represented in marine and freshwater systems and in addition reviews recent advances in community ecology.
