A synthesis of tropical freshwater systems which illustrates the basic theory of freshwater biology.
During the past century approximately fifty percent of the world's wetlands have been destroyed, largely due to human activities. Increased human population has lead to shrinkage of wetland areas, and data show that as they shrink, their important functions decline. Reduced wetland area causes more flooding in Spring, less available water during drought, greater risk of water pollution, and less food production and reduced carbon storage. Much of the remaining pristine wetland systems are found in the world's largest wetlands, and yet these areas have received surprisingly little scientific research or attention. This volume presents the views of leading experts on each of the world's largest wetland systems. Here, this international team of authors share their understanding of the ecological dynamics of large wetlands and their significance, and emphasise their need of conservation.
An international symposium on `Ocean, River and Lakes: Energy and Substance Transfers at Interfaces' was held in Nantes, France in October 1996. It was the third International Joint Conference on Limnology and Oceanography which brings together specialists of both environments. Considered to be necessary in Europe, this confrontation of two different aspects of common subjects could produce innovative approaches. The main purpose concerns scientific researches relative to the interfaces between various aquatic environment compartments. The principal treated topics are bioavailability and mobility of substances, influence of biotic and abiotic factors on transfers, and fluxes at the interfaces. It is particularly interesting to note the contribution of Limnologists and Oceanographers on the impact of nutrients and pollutants, and flux quantification of river basin inputs. As well as scientists, this book is also of interest to all engineers and consultants involved in teaching and working in aquatic management, restoration and enhancement.
These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state of the art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status a...

The present volume should be regarded as a general introduction to the subject of ancient lakes. The special nature and environments of the ancient lakes and extant biodiversities are briefly outlined. Tempo and mode of intra-lacustrine speciation are discussed and various factors affecting speciation and extinction events are listed.
