Biological Invasions
This new volume on Biological Invasions deals with both plants and animals. It differs from previous books on the subject by extending from the level of individual species to an ecosystem and global level. Topics of highest societal relevance, such as the impact of genetically modified organisms, are interlinked with more conventional ecological aspects, including biodiversity. The combination of these approaches is new and makes compelling reading for researchers and environmentalists. The book’s 22 chapters cover a huge range of subjects relevant to the field. These include pathways of biological invasions (e.g. ballast water, waterways), traits of successful invaders (e.g. chemical weapons, empty niches), and patterns of invasion and invasibility, such as man-induced predisposition by fire, land use and eutrophication, and the role of climate change.
Biological adhesives
Many plants, animals, and microbes use adhesive polymers and structures to attach to inert substrates, to each other, or to other organisms. This is the first major review that brings together research on many of the well-known biological adhesives. Emphasizing the diversity of biological adhesives and associated adhesion processes, it deals with bacteria, fungi, algae, and marine and terrestrial animals. It bridges a variety of disciplines including biochemistry, molecular biology, biomechanics, bioengineering, microbiology, organism structure and function, and ultrastructure. As we learn more about the molecular and mechanical properties of these adhesives, we begin to understand why they adhere so well and how they develop cohesive strength. With this understanding comes the prospect of developing synthetic or semi-synthetic adhesives with broad applications in areas such as medicine, dentistry, and biotechnology. The book is suitable for both industrial and academic researchers.

Au-delà de linformation, la prévention : Par l’équipe du département de prévention Épidaure = Prevention goes beyond information : By the Epidaure Prevention department team
The prevention of the most frequent and deadly pathologies (cancers, cardiovascular diseases, accidents) essentially involves modifying risky behavior, a challenge which cannot be resolved by the simple dissemination of information. To be able to modify behavior, it is necessary to take into account, on the one hand, the individuals themselves and what leads them to change their ways of living and, on the other hand, the cultural, social, physical and economic environment. who shapes people and whose modifications are necessary for individual changes. Thus, preventive health actions are effective as long as they strengthen the ability to exercise control over individual and collective health determinants.
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.
Associative and endophytic nitrogen-fixing bacteria and cyanobacterial associations
Associative and Endophytic Nitrogen-fixing Bacteria and Cyanobacterial Associations This book is part of the seven-volume series that was launched a few years ago with the ambitious objectives of reviewing the field of nitrogen fixation from its earliest beginnings through the millennium change and of consolidating the relevant information - from fundamental to agricultural and environmental aspects – all in one place. Volume 5 covers the biology of bacteria that associate with n- leguminous plants. The subject matter includes a wide range of associations; it covers the bacterial species that associate either with the surface or within the tissues of grasses (often referred as plant growth-promoting rhizobacteria) and also the symbiotic associations that cyanobacteria form with fungi, algae, and both lower and higher plants. This volume does not deal with the Frankia-actinorhizal plant associations, which is the topic of Volume 6
Association Mapping in Plants
For the past decade, there has been success in using conventional map-based strategies in identification and cloning of quantitative trait loci (QTL) in model plant species including tomato and Arabidopsis. These quantitative traits are generally the products of many loci with varying degrees of effect upon the observed phenotypes. Recently, a new approach to genetic mapping has emerged called association mapping. This new technique takes into account the thousands of genes to evaluate for QTL effect and is a more efficient approach that does not require generation of segregating populations/large numbers of progeny. As it can utilize all of the historic recombination events in a diverse population of individuals it can generate higher resolution genetic maps and, is needed to complement current map based cloning methods.
Assessing Race, Ethnicity and Gender in Health
Where there are patients, clients, or study participants, there are data. And when data involve personal variables of race, ethnicity, gender, and/or sexual orientation, questions of relevance and marginalization often arise. Assessing Race, Ethnicity, and Gender in Health brings needed clarity to the debate by identifying the ethical issues as well as the technical challenges inherent in measuring these elusive concepts.
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.
