Biodiversity Conservation and Phylogenetic Systematics : Preserving our evolutionary heritage in an extinction crisis
This book brings an updated state of the art of phylogenetic diversity in conservation biology. Nineteen chapters written by scientists from research institutions of fourteen countries demonstrate that approaches for preserving the evolutionary heritage are now very tuned into human impacts and sustainability issues. The questions, methods and applications around which it is organized show the importance of phylogenetic diversity in avoiding biodiversity losses in the present extinction crisis. They touch important points such as the way we value phylogenetic diversity, the importance of thinking at a much wider sample of the Tree of Life, the choice of adequate measures. In methods section, new solutions, such as dealing with abundances, sampling effort, or with information coming from conflicting phylogenetic trees are provided. Application section includes study cases of different groups of organi
Biodiversity and Ecophysiology of Yeasts
In the last few decades more and more yeast habitats that were not investigated earlier, spanning cold climates to tropical regions and dry deserts to rainforests, have been explored. As a result, a large body of ecological data has been accumulated and the number of known yeast species has increased rapidly. This book provides an overview of the biodiversity of yeasts in different habitats. The recent advances achieved by the application of molecular biological methods in the field of yeast taxonomy and ecology are also incorporated in the book. Wherever possible, the interaction between yeasts and the surrounding environment is discussed.
Biodiversity and Conservation in Europe
This book brings together a selection of original studies submitted to Biodiversity and Conservation that address biodiversity and conservation in Europe. Europe is certainly the most intensively inventoried region of the world; detailed maps are available for species distributions while action plans are being drawn up for species under threat. At the same time, the wildlife of Europe has been subject to enormous human pressures, with limited ‘wilderness’ sites remaining in most countries. Europe consequently presents a case-study of what the human impact on biodiversity has been, and also what can be done to improve the situation.
Biocombinatorial approaches for drug finding
Genome- and proteome-based research is generating a significant increase in the number of available drug targets. Correspondingly there is an increasing need for novel, diverse compounds, particularly based on natural compounds, as screening resource

Bacteriocins : Ecology and Evolution
Microbes produce an extraordinary array of defense systems. These include bacteriocins, a class of antimicrobial molecules with narrow killing spectra, produced by bacteria. The book describes the diversity and ecological role of bacteriocins of Gram-positive and Gram-negative bacteria, presenting a new classification scheme for the former and a state-of-the-art look at the role of bacteriocins in bacterial communication. It discusses the molecular evolution of colicins and colicin-like bacteriocins, and provides a contemporary overview of archaeocins, bacteriocin-like antimicrobials produced by archaebacteria. Furthermore, various modeling (in silico) studies elucidate the role of bacteriocins in microbial community dynamics and fitness, delving into rock-paper-scissors competition and the counter-intuitive survival of the weakest. The book makes compelling reading for a multi-faceted scientific audience, including those working in the fields of biodiversity and biotechnology, notably in the human and animal health domain.
Asymmetric Cell Division
Cell biologists have recently become aware that the asymmetry of cell division is an important regulatory phenomenon in the fate of a cell. During development, cell diversity originates through asymmetry; in the adult organism asymmetric divisions regulate the stem cell reservoir and are a source of the drift that contributes to the aging of organisms with renewable cell compartments. Because of the concept of semi-conservative DNA synthesis, it was thought that the distribution of DNA between daughter cells was symmetric. The analysis of the phenomenon in cells during mitosis, however, revealed the asymmetry in the distribution of the genetic material that creates the drift contributing to aging of mammals. On the other hand, cancer cells can originate from a deregulation of asymmetry during mitosis in particular during stem cell expansion. The book describes the phenomenon in different organisms from plants to animals and addresses its implications for the development of the organism, cell differentiation, human aging and the biology of cancers.
Ascochyta blights of grain legumes
Ascochyta blights consistently affect large areas of grain legume production (pea, lentil, chickpea and faba bean) in all countries where they are cultivated. These diseases are capable of causing large yield losses under conducive environmental conditions. This book considers the state of the art by taking a comparative approach of Ascochyta blight diseases of cool season food and feed legumes. Topics considered are pathogen diversity, legume genetics and breeding, and integrated disease management.
Arts and health promotion : Tools and bridges for practice, research, and social transformation
This book offers an overview of the beautiful, powerful, and dynamic array of opportunities to promote health through the arts from theoretical, methodological, pedagogical, and critical perspectives. This is the first-known text to connect the disparate inter-disciplinary literatures into a coherent volume for health promotion practitioners, researchers, and teachers. It provides a one-stop depository for using the arts as tools for health promotion in many settings and as bridges across communities, cultures, and sectors.
Arthropod Diversity and Conservation
Despite their enormous bulk and complexity of architecture, plants make up only around a quarter of a million of the 8 million or so species on Earth. The major components of biodiversity, instead, are the smaller, largely unseen, silent majority of invertebrates – most of which are arthropods. Vertebrates, a mere blip on the biotic horizon, are elevated in importance in the bigger scheme of things only by the human psyche. This collection of more than 30 peer-reviewed papers focuses on the diversity and conservation of arthropods, whose species inhabit virtually every recess and plane – and feature somewhere in virtually every food web – on the planet. Highlighting issues ranging from large-scale disturbance to local management, and from spatial heterogeneity to temporal patterns, these papers reflect some of the most exciting new research taking place today – and in some of the most biodiverse corners of the planet.
Aquatic Biodiversity II : The Diversity of Aquatic Ecosystems
The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers
Antimalarial medicinal plants
Malaria continues to affect a large population of the world, especially in third world countries. The spread of drug-resistant parasites demonstrates the need for antimalarial agents with various modes of action. The search for remedies derived from medicinal plants for the treatment of malaria is reliant on accurate ethnobotanical and ethnopharmacological information obtained from traditional medical practitioners. Antimalarial Medicinal Plants provides information on bioactive compounds and therapeutic potentials of several antimalarial plant species found around the globe. This book evaluates these plant species with respect to their biology, diversity, distribution, and pharmacological values.
An ecological and societal approach to biological control
Biological control is among the most promising methods for control of pests (including vectors), diseases and weeds. In this book ecological and societal aspects are for the first time treated together. In an ecological approach the aim is to evaluate the significance of certain biological properties like biodiversity and natural habitats. Also, it is important to see biological control from an organic (or ecological) farming point of view. In a societal approach terms like ‘consumer’s attitude’, ‘risk perception’, ‘learning and education’ and ‘value triangle’ are recognised as significant for biological production and human welfare.
Alternative Splicing and Disease
Splicing of primary RNA transcript, i.e. removal of introns and joining of exons to produce mature mRNAs competent for translation into proteins, is a quasi-systematic step of gene expression in higher organisms. However, this process is not unequivocal but can follow alternate pathways. Alternative splicing of a given transcript can therefore yield several distinct mRNAs encoding as many different proteins. Its full biological significance has not been appreciated until it was recognized that alternative splicing is so general as to affect about 75% of all human genes. Therefore, alternative splicing not only vastly increases protein diversity but also offers numerous opportunities for aberrant splicing events with pathological consequences.
Algae and Cyanobacteria in Extreme Environments
ALGAE AND CYANOBACTRIA IN EXTREME ENVIRONMENTS is a unique collection of essays, contributed by leading scientists from around the world, devoted to algae – and some related microbes – observed in unexpected harsh habits, which it seems are an oasis or Garden of Eden for these organisms. This timely book on Extremophilic alga, including its especially impressive micrographs, may provide clues about the edges of life on Earth and possibly elsewhere in the universe. This volume is a must for students of the field of biodiversity, as well as those in Phycology, ecology and general biological research.
Agroforestry in Europe : Current Status and Future Prospects
Brings together some of the most important current research in European agroforestry, and evaluates the current scope and future potential of agroforestry across the EU.While the majority of Europe’s agroforestry practices are currently focused in the Mediterranean, this volume draws together examples from a wide range of countries – including Greece, Spain, the UK, Hungary, Germany, Italy, the Netherlands, Switzerland, France and Slovenia. The book also covers a range of agroforestry types, including silvopastoralism – Europe’s predominant form of agroforestry – as well as alley cropping, forest farming, silvoarable systems and the use of trees for shelter. Through these examples the book also discusses the potential roles for these traditional land management systems in addressing both environmental issues such as water quality, biodiversity conservation, desertification, ecosystem services and socioeconomic issues such as rural population stabilization.

Advances in Integrated Soil Fertility Research in sub-Saharan Africa : Challenges and Opportunities
Food insecurity is a central concern and a fundamental challenge for human welfare and economic growth in Africa. Low agricultural production, results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. Land degradation and soil fertility depletion are considered the major threats to food security and natural resource conservation in sub-Saharan Africa (SSA). Investments in technology, policy and institutional reforms are needed to increase agricultural productivity to ensure food security and sustained national economies. Past research has generated numerous soil fertility management technologies which if adopted could propel the African continent out of the poverty trap. However, these technologies have had little, if any, impact due to low adoption by the smallholder farmers.
