Book Description
Ecosystems can be considered as dynamic and interactive clusters made up of plants, animals and micro-organism communities. Inevitably, mankind is an integral part of each ecosystem and as such enjoys all its provided benefits. Driven by the increasing necessity to preserve the ecosystem productivity, several ecological studies have been conducted in the last few years, highlighting the current state in which our planet is, and focusing on future perspectives. This book contains comprehensive overviews and original studies focused on hazard analysis and evaluation of ecological variables affecting species diversity, richness and distribution, in order to identify the best management strategies to face and solve the conservation problems.

Book Description
This volume does not aim at merely adding to the vast and increasing number of individual publications on `biodiversity'. Rather it is our objective to investigate biodiversity on the previously little studied coenosis and landscape levels. Phytosociological and animal-ecological fields are considered, as well as theoretical approaches to biodiversity and aspects of its application in nature and landscape protection and preservation. Since biodiversity has so far been predominantly studied in the Anglo-American area, it seemed to be of value to discuss this complex topic from a central and southern European viewpoint, based on data gathered in these regions, and thus to promote a global discussion.

Book Description
The book describes richness and diversity of Georgia’s vegetation. Contrasting ecosystems coexist on the relatively small territory of the country and include semi-deserts in East Georgia, Colchic forests with almost sub-tropical climate in West Georgia and subnival plant communities in high mountains. West Georgia lacks xerophilous vegetation zone and mesophilous forest vegetation spreads from the sea level to subalpine zone. The Colchic refugium (West Georgia) ensured survival of the Tertiary’s mesophilous forest flora. Vertical profile of the vegetation is more complex in East Georgia with semi-desert, steppe and arid open forest zone. In South Georgia the montane zone represented by montane steppe is devoid of forests

Book Description
In the Mediterranean basin, one of the richest biodiversity hotspots on the planet, evergreen oak woodlands are essential elements. This book facilitates a more detailed ecological understanding of Quercus calliprinos, a lesser-known Mediterranean forest species that could make an important contribution to the struggle to counteract climate change and biodiversity loss. The book also discusses two further crucial species of the Mediterranean evergreen woodlands, Quercus ilex and Quercus suber, focusing on the role of forest management in their conservation.

Book Description
Ladies a n d g e n t 1 e m e n , I have the pleasure to welcome you here in Prague in the name of the Czechoslovak Academy of Sciences and to open the Fifth Inter national Colloquium on Soil Zoology. We are very glad that Czecho slovakia was chosen for this important meeting. It is clear to all of us that the soil plays and will play a de cisive part in providing food for the explosive increase of human pop ulation. For this reason we watch with great anxiety the negative influence of human activities on the environment accompanied also by the other destructive intervention into the soil ecosystem, its devas tation by inefficient management, application of herbicides and pesti cides pollution by the waste products of industry and human settlements. The basis for solving these accumulating and now sometimes latent prob lems is among others a good knowledge of the role of soil organisms in the cycles of materials and in the energy flow. Soil zoology as a part of soil biology is still at the beginning of this trend The lack of in formation about life in soil is obvious when compared with the results of a related biological science dealing with the water ecosystem.

Book Description
Wetlands are very sensitive ecosystems, functioning as a habitat for many organisms. Protection and regeneration of wetlands are of great importance in ecological research and in nature conservation. A huge amount of research has been done on the hydrology, plants and animals in wetlands. Knowledge about soil organisms and soil ecological processes of wetlands is still lacking. This knowledge is a prerequisite for landscape planning purposes or climate change predictions. In the case of climate change, trace gas emissions from wetlands are of great interest. The authors provide an overview of the state-of-the-art on soil ecology in wetlands. The book is divided into the following main chapters: 'Wetlands as habitats for soil organisms', 'Soil ecological processes in fens and floodplains', 'Carbon and nitrogen dynamics in soils with different water regimes' and 'Trace gas emissions'.

Book Description
The Handbook of Vegetation Science is growing. After the first volumes und er my editorship have appeared the interest of the scientific community has been revived and many new volume editors have started their work. The present volume wasjointly designed by Drs. J. White and W. Beeftink. Due to unforseen developments Dr. White signs now as the sole editor. The development of this volume within the series had a special history as Dr. White pointsout in his preface. Adding to this I need only to state that I found it essential to include the topic of this volume into a Hand book of Vegetation Science. lt was included therefore in my first revised Iist of topics to be included in the Handbook when I took over from Dr. Tüxen. It is a great pleasure for me to see this volume appear. Having read through the many contributions to this volume I can certainly congratu late Drs. White and Beeftink for their success in generating so much interest in this volume among their colleagues. The cooperation on this volume is forme the first sign that the new concept of the Handbook has been understood by the generation of scientists which I have to address. The influence this volume will have on the field ofplant population studies only time can teil. It appears to me, however, that this volume will become a standard resource for some future. Dr. White asked me to have this volume dedicated to Dr. Rabotnov.

Book Description
Radiobiology has made great steps forward in the last five years in the development of new mechanisms forming the basis of various radiation effects, specifically among the mechanisms of low rate irradiation by low doses. Investigations of radiation apoptosis, radiation hormesis, radioadaptive response, and by-stander effects have been intensively developed. Processes of premature ageing induced by irradiation are examined. All these questions are discussed here. The greatest part is devoted to assessments of the health of the population irradiated inhabiting the radionuclide-contaminated territories and people from other regions of the former USSR involved in the liquidation on the accident consequences.
