Book Description
The plankton community is a heterogenous group of tiny plants (phytoplankton) and animals (zooplankton) adapted into live in marine as well as freshwaters. Plankton is the productive base of both freshwater and marine ecosystems, providing food for larger animals and indirectly for humans, so plankton constitutes the basic food sources for any aquatic ecosystem, which supports fish and other aquatic animals. The phytoplankton may become increasingly important in space travel as a source for food and for gas exchange. The present book entitled "Freshwater Plankton and Macrophytes of India" comprises of three sections and the whole subject has been divided into nine chapters, which includes phytoplankton, zooplankton and macrophytes with their introduction, classification, adaptation methods for study, importance, key to identification and taxonomic description of species. The details should help the students as well as researchers to be thorough in the method of collection and identification of different planktonic species. The number of references cited should be adequate to permit easy access to additional information. This book will be immense use to all those who study or teach aquatic ecology and hydrobiology. Not only this, the present book will also be helpful for students, research scholar, professors, scientists as well as limnologists.

Book Description
Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.

Book Description
The book , ‘An Introduction to Phytoplanktons - Diversity and Ecology’ is very useful as it covers wide aspects of phytoplankton study including the general idea about cyanobacteria and algal kingdom. It contains different topics related to very basic idea of phytoplanktons such as, types ,taxonomic description and the key for identification etc. Together with it, very modern aspects of phytoplankton study including different methodologies needed for research students of botany, ecology, limnology and environmental biology are also included. The first chapter is very basic and informative and describes algal and phytoplankton classification, algal pigments, algal bloom and their control, algal toxins, wetlands algae, ecological significance of phytoplanktons etc. A general key for identification of common phytoplankton genera is also included for students who will be able to identify these genera based on the light microscopic characters. In Chapters 2-4, different aspects of phytoplankton research like primary productivity, community pattern analysis and their ecological parameter analysis have been discussed with detailed procedures. Statistical analysis is also discussed in detail. Chapter 5 includes case studies related to review, phytoplankton diversity and dynamics.

Book Description
Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology.Key Features* The first complete accounting of North America's freshwater algal genera in more than 50 years* Includes a guide to the current literature on species identification in each group of algae* High-quality photographs and drawings of more than 770 genera* A clear, easy-to-use introductory key to the diagnostic chapters* Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae* Contributions from 27 experts in all areas of freshwater algae* Extensive literature citations* Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich

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
Phytoplankton plays a key role in aquatic ecosystems where it is the major biomass producer. Phytoplankton is characterised by a high time-space variability which is determined by abiotic and biotic factors. In this book, the role of abiotic factors (light, temperature, nutrients, wind, hydrodynamics, CO2 and UV radiation) and biotic factors (bacteria, zooplankton, macrophytes and fish) is discussed. Anthropogenic pressure can alter those environmental factors, causing undesired changes in the composition and biomass of phytoplankton. This book emphasises the effects on water quality, but bottom sediment is also analysed. The effectiveness of management measures to restore impacted ecosystems is reviewed and ecological modelling is used as a prediction tool. In this book, the authors describe case studies in different systems such as natural lakes, reservoirs, marine systems and aquatic microcosm systems, covering a wide range of geographic areas from African tropical lakes and Brazilian subtropical lakes to peri-Alpine European lakes.
