Book Description
This volume originated in a belief, shared by the two editors, that the time was ripe for a world-wide survey - or at least sampling - of seasonality in freshwater phytoplankton. An opportunity was provided by the International Limnological Congress (S. I. L. ), held at Lyon in August 1983, to plan a one-day symposium on the topic. From this enjoyable and successful occasion, augmented by additional written contributions, the present volume has emerged. As convenors and editors, we are grateful to the contributors for their cooperation in this international venture. The seasonality of phytoplankton is widely conditioned by that of climate. Thus one may expect to find the geographical differentiation of climatic patterns reflected in the seasonal patterns of algal occurrence. Diversity in the global perspective is also introduced by considerations of geomorphology, geochemistry, and genotypically determined response. Nevertheless, the historical base of our subject is firmly rooted in the north-temperate zone. From its fresh waters, and seas, there have evolved virtually all of the approaches and techniques now being applied to the analysis of phytoplankton seasonal dynamics.

Book Description
The anatomy of water, water as a substance, water as a medium, the principles of the hydrologic cycle, the economics of water, and challenges are all covered in the first chapter of this book. The horizon of the tropical world, the environment, particularly the tropical environment, aquatic biome, tropical aquatic bionetwork, concept of biosphere, and tropical limnology are all covered in the second chapter. The third chapter covers the following topics: the origins of lakes, general lake classification, tropical lakes, lake morphometry, morpho-edaphic index, trophic status index of lakes, wetlands, and mangroves in tropical regions. The lotic environment is the main topic of the fourth chapter, which also covers the idea of stream order, the differences between rivers and streams, the river continuum, physical, chemical, and biological characteristics, and adaptations of fish found in hill streams. Chapter five covers the prokaryota, cyanobacteria, freshwater biota, and water-adapted organisms. The sixth chapter focuses on the algal communities Xanthophyceae, Euglenophyceae, Bacillariophyceae, Chrysophyceae, Phaeophyceae (brown algae), and Chlorophyceae. The seventh and last chapter covers the following topics: Protozoa, Porifera, Rotifera, Coelenterata, Annelida, Arthropoda, Crustacea, Aquatic Insects, Mollusca, Echinodermata, and Brachiopodaa.

Book Description
This volume summarises the outcome of the 13th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP) on if, and if so under what conditions phytoplankton assemblages reach equilibrium in natural environments. Quite a number of ecological concepts use terms such as: ecological equilibrium, stability, steady-state, climax, stable state, etc. However, these ecological concepts often have been "translations" of scientific theories developed in physics or chemistry but they almost always lack scientific corroboration, the problem being that often these concepts remain vague and they are not formally defined. Here an attempt to formally recognize what "equilibrium" is in phytoplankton ecology is traced. The book also contains papers by leading scientists on the taxonomy of two selected key groups: cryptomonads and filamentous cyanoprokaryotes. This volume is addressed to all those involved in phytoplankton taxonomy and ecology and in ecology itself.

Book Description
The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.

Book Description
Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study.

Book Description
Advances in our understanding of the nitrogen cycle and the impact of anthropogenic activities on regional to global scales depend on the expansion of scientific studies to these fast-developing regions. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
