These proceedings present the most up-to-date information on the interrelations between microorganisms and plants in the rhizosphere, and the possibility of utilizing these relationships to improve plant growth, health and yields. The application of some biological preparations may in the future partially replace the use of agrochemicals and thus contribute to environmental improvement and enhancement of the quality of soil, water and foodstuffs. The Symposium brought together specialists from fifteen countries to assess the advances in a field which has recently attracted considerable interest and is also important for society at large. The book contains over sixty contributions from rhizosphere microbiologists, focusing on the study of the function of microorganisms in the root system of crop plants and in its immediate vicinity, the effect of the plants themselves on this function, the interrelationships among different microorganisms in the rhizosphere and the elucidation of the mechanisms of microbial action in the agroecosystem. All these lines of research are intimately associated with the problems of soil fertility and crop yields, which in turn have a direct bearing on the nutrition of mankind and on environmental protection. The papers have been divided into four topics: symbiotic microorganisms in the root system; associative microorganisms in the root system; soil-borne phytopathogenic and phytotoxic microorganisms; and microbial preparations stimulating growth and improving the plant health. Each section starts with invited lectures from outstanding specialists. The work includes numerous tables, figures and references. The volume is primarily directed at soil microbiologists, plant pathologists and physiologists, ecologists as well as specialists in agronomy and environmental protection.

"A book about the influence of estrogens on memory would have been unthinkable as recently as 30 years ago. Although a few small studies in the late 1970's reported a beneficial effect of estrogens on memory in human women (Hackman and Galbraith, 1976; Fedor-Freybergh, 1977), examination of the role of estrogens in memory did not truly capture more widespread attention until the pioneering work of Barbara Sherwin and colleagues in 1988 and beyond. In her initial paper, Sherwin showed that bilateral removal of the ovaries (aka surgical menopause) led to impaired short-term and long-term memory, whereas treatment of surgically menopausal women with estradiol alone, testosterone alone, or estradiol plus testosterone prevented this decline (Sherwin, 1988). As a search for the terms "estrogen" and "memory" in PubMed illustrates, well over 2000 papers have been published on the subject of estrogens and memory in the ensuing decades. The vast majority of these studies have focused on the hippocampus, a bilateral medial temporal lobe structure essential for the formation of episodic memories, particularly those with spatial, contextual, relational, temporal, and recognition components (Olton et al., 1979; Morris et al., 1982; Kim and Fanselow, 1992; Squire, 1992; Cohen and Stackman, 2015; Tonegawa et al., 2015; Eichenbaum, 2017). Although various forms of learning and memory are mediated by numerous brain regions, including the prefrontal cortex, medial temporal lobe cortices, amygdala, striatum, and cerebellum, the hippocampus has received the lion's share of attention due to its central importance for episodic memory formation. Hippocampal damage produces profound retrograde amnesia for facts and events, as well as anterograde amnesia for new information and impairments in spatial navigation (Winocur, 1990; Anagnostaras et al., 2001; Clark et al., 2002; Gilboa et al., 2006). Hippocampal dysfunction in middle-aged and aged subjects is a primary contributor to age-related memory decline (Golumb et al., 1996; Grady et al., 2003; Apostolova et al., 2010; Burke and Barnes, 2010; Small et al., 2011; Yassa et al., 2011), and has also been implicated in the cognitive impairments observed in diseases such as schizophrenia and depression (Small et al., 2011; Nakahara et al., 2018; Santos et al., 2018; Ott et al., 2019). Moreover, the hippocampi of patients with Alzheimer's disease are substantially atrophied and burdened with copious amounts of amyloid plaques and neurofibrillary tangles, the hallmark pathologies of this insidious disease (Hyman et al., 1984; Walsh and Selkoe, 2004; Selkoe and Hardy, 2016). As such, understanding how estrogens influence hippocampal functioning may provide important insights not only about the fundamental neurobiology of memory processes, but also into the etiology of neuropsychiatric and neurodegenerative diseases"--

Epigenetics commonly acts at the chromatin level modulating its structure and consequently its function in gene expression and as such plays a critical role in plant response to internal and external cues. This book highlights recent advances in our understanding of epigenetic mechanisms as a major determinant through which internal and external signals, such as those occurring during hybridization, flowering time, reproduction and response to stress, communicate with plant cells to bring about activation of multiple nuclear processes and consequently plant growth and development. The outcome of these processes may persist for generations long after the initial cues have expired and may contribute to plant evolution.

Since the beginning of industrialization in the last century, a steady increase in energy consumption can be observed. At the same time, energy generation switched from wood and coal to predominantly oil, coal and natural gas. Soon, many countries became aware of the fact that the resources of fossil fuels, especially of oil and natural gas are finite. Diversification of energy sources became a requirement for the future. Governments expressed their concern by setting up natural energy programmes while international organisations undertook assessments of the global energy resources and possible rates of supply and substitution. When it comes to setting up energy policies, the following factors must be taken into consideration: population growth, level and nature of socio-economic activity, the costs of energy, the adequacy and reliability of supply, the availability of technology and supporting infrastructure, the success of energy conservation programmes and concern about the environment, safety aspects of production and use of energy as well as educational efforts toward a rational use of energy. When we express our most urgent concern, the long-term global energy provision, experts offer four interrelated partial strategies: - the strategy of rational use and conservation of energy - the strategy of using renewable energy sources - the coal strategy including coal gasification and liquefaction - the nuclear power strategy. Any strategy, however, for securing future energy supply has, from my point of view, to be thoroughly examined as to its impact on the environment.

Based on work by the Miombo Network in southern Africa, this book helps decision-makers and general readers alike improve their understanding of the socio-ecology of the Miombo woodlands across southern Africa. It also highlights the importance of and the need for further research on the unique Miombo ecology and its link with economic development. One major challenge facing these woodlands is the influence that direct (both natural and anthropogenic) and indirect drivers of change, as well as interactions between these, have had over the centuries. As such the book explores the socio-economic and ecological interactions that occur in these woodlands and discusses the need for further research to provide a better understanding of these interactions. Drawing on data and information from numerous studies conducted in the last 20 years, the book presents a comparative analysis of policy changes and management experiences in the countries concerned. It also addresses issues of global climate change, since they have an impact on Miombo ecosystem management and restoration, and provides future projections based on an assessment of how climate change has affected the Miombo woodlands in the past.
