This richly illustrated book, replete with several QR codes for short, original films, focuses on being compassionate to creatures less than ourselves.From the Introduction: We go through our lives consuming the flesh of other living animals despite our capacity to refrain from doing so. It has been estimated that we kill 55 billion animals each year for food (Hussain). We are willingly neglecting the welfare of 55 billion lives every year when we have other food options for our survival. In the 21st century, we have a moral duty and responsibility not to continue the horrendous suffering endured by animals simply for profit and appetite. Ending the unimaginable suffering of animals for which we bear a responsibility will increase our own eudaimonia since being compassionate to others also benefits us. As we expand our moral circle of compassion and consideration, the individual self can gain a greater sense of well-being.

This book is reflecting upon core theories in evolutionary biology ¿ in a historical as well as contemporary context. It exposes the main areas of interest for discussion, but more importantly draws together hypotheses and future research directions.The Modern Synthesis (MS), sometimes referred to as Standard Evolutionary Theory (SET), in evolutionary biology has been well documented and discussed, but was also critically scrutinized over the last decade. Researchers from diverse disciplinary backgrounds have claimed that there is a need for an extension to that theory, and have called for an Extended Evolutionary Synthesis (EES).The book starts with an introductory chapter that summarizes the main points of the EES claim and indicates where those points receive treatment later in the book. This introduction to the subjects can either serve as an initiation for readers new to the debate, or as a guide for those looking to pursue particular lines of enquiry. The following chapters are organized around historical perspectives, theoretical and philosophical approaches and the use of specific biological models to inspect core ideas. Both empirical and theoretical contributions have been included. The majority of chapters are addressing various aspects of the EES position, and reflecting upon the MS. Some of the chapters take historical perspectives, analyzing various details of the MS and EES claims. Others offer theoretical and philosophical analyses of the debate, or take contemporary findings in biology and discuss those findings and their possible theoretical interpretations. All of the chapters draw upon actual biology to make their points. This book is written by practicing biologists and behavioral biologists, historians and philosophers - many of them working in interdisciplinary fields. It is a valuable resource for historians and philosophers of biology as well as for biologists. Chapters 8, 20, 22 and 33 are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This volume is a monograph of the genus Diplusodon (Lythraceae), written by the world authority on this plant group. Diplusodon is a monophyletic genus of shrubs and subshrubs, with showy, 6-merous, actinomorphic flowers, and floral tubes on which the sepals alternate with conspicuous epicalyx segments. The capsular fruit contains winged seeds and, uniquely for the family, is divided by a bipartite placenta with two semi-lunate septa. Diplusodon is the second largest genus in the Lythraceae and occurs mostly in the Cerrado Biome, the floristically diverse savannah that covers more than two million km2 of the Central Brazilian Plateau, extending west into Bolivia, south to Paraguay and east to the Caatinga. A total of 104 species and eight varieties are recognized in the genus, for which 46 lectotypes, one neotype, one new status and one new combination are designated, nine new species are described, and 15 taxaare placed in synonymy. New information on floral and vegetative morphology, pollen, cytology, chemistry, floral biology, and habitat are provided for the genus. In addition, keys to the species are accompanied by descriptions, illustrations, distribution maps, and assignment of conservation status.

This edited book brings together comprehensive information on various aspects of the biofortification of staple crops. It addresses the present status of food and nutritional security and highlights the importance of micronutrients in human health, a historical account of biofortification, current approaches and challenges, crop-specific biofortification efforts and various breeding approaches, including conventional, and genomics enabled improvement.  It also explains the efficacy of biofortification, bioavailability, and future thrust. It is an inclusive source of information on different aspects of micronutrients in crops of global importance.  Malnutrition is a serious global issue, with millions of people being undernourished, several suffering from micronutrient deficiencies, and the adult population struggling with obesity. Despite significant economic progress, South Asia and Sub-Saharan Africa are still home to an undernourished population. Nutrition-related health problems are related to hidden hunger and are widespread in the developing world. Women and preschool children are more vulnerable. Even though global food production has increased manifolds, estimates indicate that over 60% of the world's population is deficient in essential micronutrients such as iron, zinc, iodine, and selenium, often causing health problems and developmental delays. Linking agricultural production with human nutrition and health is crucial for ensuring nutrition security. Much research has been carried out to assess genetic diversity related to micro-nutrients in staple crops, their bioavailability, and the efficacy of biofortified germplasm. Biofortified varieties developed in different crops through conventional breeding are being up-scaled for reducing the micronutrient deficiencies in other countries.  This book is a ready reference for researchers, academicians, extension personnel, policymakers, students, and value chain stakeholders engaged in agriculture, nutrition, and health sectors promoting nutrition-sensitive diets.
