Honighäuschen (Bonn) - Although there are some biological processes that are supported by UV radiation, most organisms are stressed by it in various ways, e.g. through DNA damage. Top international experts present an integrated overview of UV radiation and its effects on terrestrial, freshwater and marine Arctic biota. Increased stratospheric ozone depletion and the corresponding increase in ground levels of UV radiation as well as ambient, "natural" UV radiation as a key ecological factor in the Arctic spring and summer are discussed in detail. Additionally, basic information on Arctic ecosystems is given. The volume provides not only an excellent account of present-day knowledge of the subject, but also describes the state of the art on which future research can be built.

Honighäuschen (Bonn) - Harmful algal can cause a variety of deleterious effects, including the poisoning of fish and shellfish, habitat disruptions for many organisms, water discoloration, beach fouling, and even toxic effects for humans. In this volume, international experts provide an in-depth analysis of harmful algae topics and offer a comprehensive synthesis of the latest research in the field.

Honighäuschen (Bonn) - Lake Titicaca, because of its area and volume and its situation at high attitude within the tropics, is a unique hydrological site in the world. It should be noted that it stands at the transition point between two very distinct geographical regions: the desert fringe of the Pacific coast to the west and the great Amazonian forest extending to the Atlantic coast to the east. Many scientists have been attracted to the lake in the past because of its unusual limnological features. In this book the editors have compiled an exhaustive review of current knowledge from the existing literature and from the results of more recent observations. It is certain that this book will become the essential reference work for scientists wanting to make progress in revealing the lake's secrets. It can be stated unequivocally that this work constitutes a complete review of the present state of knowledge on Lake Titicaca and that it provides the latest results of research on this habitat.

Honighäuschen (Bonn) - This book is a compendium of knowledge on the useful properties of algae in the context of application as a useful component of innovative natural products. It presents all aspects of industrial applications of macroalgae biomass derived from the natural environment. Despite many interesting characteristics, algae are still regarded as undervalued raw material, therefore, present in the following chapters are not only environmental benefits arising from the development of excessive algal biomass, but also the distribution and biology of algae in natural conditions in reservoirs, methods of obtaining extracts from biomass of algae for industrial purposes. Furthermore, it also includes topics such as the use of biomass and algae extracts for the industrial purposes, in animal breeding and for agricultural purposes, as well as the economic aspects of algae biomass harvesting for industrial purposes. The book is intended for a wide audience interested in new methods of obtaining the biomass from the natural environment for industrial purposes and the manufacture of products based on bioactive substances obtained from the environment.

Honighäuschen (Bonn) - There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.

$Honighäuschen (Bonn) - Rock surfaces provide a challenging habitat for a broad diversity of micro- or small-sized organisms. They interact with each other forming complex communities as well with their substrate causing biodeterioration of rock. Extreme fluctuation in light, temperature and hydration are the main factors that determine the rock surface habitats. The habitat includes epilithic organisms which thrive on the surface without penetrating the rock, endolithic organisms which live just beneath the surface using a thin layer of the rock surface for protection against adverse conditions of the environment (e.g. light protection, storage of water) and chasmo-endolithic organisms which use fractures of the rock surface for a more habitable environment. The book will provide an overview of the various organismal groups, from prokaryotes to vascular plants and arthropods, as well as survey organism-mediated interactions with the rock surface. The latter include biogenic weathering (biogeochemistry, state-of-the art imaging methods), photosynthesis and nitrogen fixation at and inside the rock surface.$
