Phytoplankton in Turbid Environments: Rivers and Shallow Lakes by J.-P. Descy,Colin S. Reynolds,Judit Padisák Pdf

The ecology of potamoplankton has received less attention than lake plankton. These proceedings produce a synthesis of the composition, community structure and dynamics of lotic phytoplankton, which are intuitively submitted to a strong physical control in the flowing environment, perceived as much more `disturbed' than a lake, even than a well-mixed shallow one. It turns out that the boundary between the phytoplankton of rivers and lakes is not as clear-cut as was thought. In particular, most contributions provide arguments emphasizing the prominent role of physical control in both aquatic systems, especially due to the steep light gradient resulting from turbulent mixing in a turbid water column. Similarities and differences between potamoplankton and limnoplankton, largely based on the information gathered by the contributors are discussed in the introductory paper by Reynolds et al.

Phytoplankton and Trophic Gradients by M. Alvarez-Cobelas,Colin S. Reynolds,P. Sanchez-Castillo,Jørgen Kristiansen Pdf

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 are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators. Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.

European Large Lakes by Tiina Nõges,Reiner Eckmann,Külli Kangur,Peeter Nõges,Anu Reinart,Gulnara Roll,Heikki Simola,Markku Viljanen Pdf

Large lakes are important because of their size and ecological distinctiveness as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered.

Phytoplankton responses to human impacts at different scales by Nico Salmaso,Luigi Naselli-Flores,Leonardo Cerasino,Giovanna Flaim,Monica Tolotti,Judit Padisák Pdf

Phytoplankton responses to human impact at different scales provides a state-of-the-art review of changes in the phytoplankton assemblages determined by human alterations of lakes and rivers. A wide spectrum of case studies describe the effects due to eutrophication and climate change, as well as other impacts connected with watershed management, hydrological alterations and introduction of non-indigenous species. The volume also includes two wide reviews on planktonic coccoid green algae and planktic heterocytous cyanobacteria. This book is addressed to ecologists and scientists involved in phytoplankton ecology and taxonomy. Many case studies provide a sound scientific basis of knowledge for a wise management of water bodies. Previously published in Hydrobiologia, vol. 698, 2012

The Alte Donau: Successful Restoration and Sustainable Management by Martin T. Dokulil,Karl Donabaum,Katrin Teubner Pdf

Here we report on a 25-year long-term sequence of measures to return a deteriorated recreational urban lake, Alte Donau in Vienna to acceptable water quality. Metropolitan waters require focused ecosystem management plans and intensive in-lake efforts. We explored physico-chemical conditions, food web from viruses to fish and water birds, the sediments, the littoral zone and the catchment, management and urban planning, and global warming. Several restoration techniques were tested and critically evaluated. The final management plan was based on bi-stable theory. During the recovery phase, numerous surplus adjustments had to be implemented to secure sustainable achievement.

Toxic Cyanobacteria in Water by Ingrid Chorus,Martin Welker Pdf

Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers. Ingrid Chorus headed the department for Drinking-Water and Swimming-Pool Hygiene at the German Environment Agency. Martin Welker is a limnologist and microbiologist, currently with bioMérieux in Lyon, France.

Phytoplankton and Equilibrium Concept: The Ecology of Steady-State Assemblages by Luigi Naselli-Flores,Judit Padisák,Martin F. Bach Pdf

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.
