LIMNOECOLOGY THE ECOLOGY OF LAKES AND STREAMS PDF

The Ecology of Lakes and Streams Second Edition Winfried Lampert and Ulrich Sommer Successful first edition, thoroughly revised and updated Concise, readable introduction to limnoecology, placing the subject in the context of modern ecology Applies evolutionary theory to an understanding of freshwater ecosystems, thereby filling a niche between traditional limnology and evolutionary ecology Global examples encourage international appeal New emphasis on food webs, species diversity and ecosystem functioning, climate change, conservation and management New to this Edition: Thoroughly revised throughout to incorporate findings from new technologies and methods notably the rapid development of molecular genetic methods and stable isotope techniques that have allowed a rapid and ongoing development of the field. New emphasis on food webs, species diversity and ecosystem functioning, climate change, conservation, and management Limnoecology The Ecology of Lakes and Streams Second Edition Winfried Lampert and Ulrich Sommer Description This concise, readable introduction to limnology the science of investigating the structure and function of inland waters , places the subject in the context of modern ecology. Unlike most ecological textbooks, which use examples taken almost exclusively from terrestrial systems, this book integrates the fields of limnology and ecology by presenting empirical data drawn entirely from freshwater ecosystems in order to advance ecological theories limnoecology. This second edition builds upon the strengths of the first with the structure of the book following the same hierarchical concept of ecology, from habitat properties, individuals, populations, coupled populations and communities to ecosystems. However, it has been thoroughly revised throughout to incorporate findings from new technologies and methods notably the rapid development of molecular genetic methods and stable isotope techniques that have allowed a rapid and ongoing development of the field.

A second, revised German edition was released in The second English edition that is now available is not a direct translation, but an updated and extended version of the second German edition.

The chapter on ecological genetics now includes several subchapters on the development and application of molecular genetic methods. Similarly, the use of stable isotopes for the analysis of aquatic food webs and carbon cycling has been incorporated. Subchapters and sections on species diversity and ecosystem functioning, climate change and conservation management complement this new edition.

The general purpose and the style of this textbook remained unchanged. Throughout this text, interactions between organisms and populations are discussed with respect to their selective advantage or disadvantage for the players.

Although ecological research is often concerned with proximate factors, Lampert and Sommer always quest for the ultimate factor that may provide a gain in fitness for a certain genotype. This is obvious alone from the uneven length of the individual chapters. Following two short introductory chapters on the relationship between ecology and evolution Chapter 1 and methods of ecological research Chapter 2 , the physical, chemical and hydroecological features of aquatic habitats are briefly dealt with in the third chapter.

The following chapters follow a hierarchical sequence from individuals Chapter 4 through populations Chapter 5 to communities Chapter 7.

Some ecosystem perspectives Chapter 8 , including man-made alterations and threats, round off the ecological play. The final chapter critically assesses the role of ecology as a scientific discipline in the present societal context.

The authors provide a plethora of examples, many of which originate from their own research and research conducted by their associates and collaborators.

Presently, Sommer is the leading scientist of a large German research programme investigating the shift of aquatic communities in response to the climate change. Accordingly, he provides many examples of the issues of biodiversity and climate change.

Yet, the reader does not get the impression that the various chapters have different authors; the text is easy to read, and the style of the book is consistent, reflecting the long-standing cooperation between these two eminent scientists.

Both authors mainly worked on mesotrophic to eutrophic temperate lakes e. Lake Constance. Accordingly, the selection of case studies focuses on the central European experience and is biased towards lake plankton. The authors are aware that some of their insight gained in north-temperate lakes cannot easily be applied to tropical or ultra oligotrophic lakes; one such an example is the seasonal succession of plankton outlined early in their conceptual model Sommer et al.

Results from many case studies and laboratory experiments are illustrated in numerous clear figures, most of them conveniently found on the same or the opposing page. Text boxes explain the key methods such as molecular analysis of bacterial diversity and quantification of selectivity in some detail.

Review questions at the end of most chapters help students to consolidate their knowledge. A table of abbreviations and a glossary facilitate rapid orientation for undergraduate students and researchers from disciplines outside limnology. With approximately pages, this textbook cannot cover all aspects of freshwater ecology. Fields that are left out are, for instance, paleolimnology and hydroecology ecohydrology. Fisheries ecology has been treated cursorily, mainly with respect to predation and cascading effects on the food web.

Microbes other than small eukaryotic algae receive little attention. The lengthy discussion of the mechanistic theory of competition appears somewhat outdated considering that, as the authors concede, equilibrium conditions are rarely met in situ.

Surprisingly, there is no hint that oscillations and chaotic fluctuations in species abundances allow the coexistence of many species depending on a limited number of resources Huisman and Weissing, The potential significance of deterministic chaos and recent experimental evidence for its existence are briefly discussed in the chapter on populations.

The emphasis the authors place on explaining competitive interactions and the predictive power of mechanistic models under equilibrium conditions illustrates their general view of ecology and natural selection.

Within this context, I am unaware of any other textbook that explains basic ecological principles and evolutionary oriented, ecological thinking better than this one.

It presents several new developments in ecology and emphasizes evolutionary ecology. Unlike most ecology textbooks, which use examples taken almost exclusively from terrestrial systems, this book focuses on the relationship between limnology and ecology by presenting empirical data drawn entirely from limnology in order to advance more general ecological theories. All the experimental and observational examples are drawn from the same set of organisms of inland waters and their ecosystems. This unique text covers all the key issues of limnology, while its structure and underlying concepts conform to ecology, making it equally useful in both fields.
