Phylogenetics often uncovers contradicting hypotheses regarding the relationships within the same group of organisms, a phenomenon known since the beginning of the molecular systematics era. While, historically, single marker-based analyses produced discordance, nowadays entire cellular genomes or portions of the same genomic compartment conflict with others or the rest, respectively. In contrast to the beginning of the molecular systematics era, when adding markers and taxa offered a way out of systematic errors, genome inference-based incongruences cannot be addressed and explained easily. Disagreeing phylogenomic hypotheses might originate from various evolutionary processes, including but not limited to hybridization or incomplete lineage sorting, thereby leading to gene tree-versus species tree-associated discrepancies. Today, this can be expanded to genome discordance, where phylogenomic signals of organellar genomes (plastid, mitochondrial) and the nuclear genome disagree due to intrinsically different coalescent paths or phenomena like organelle capture.

Big data is revolutionizing our ability to measure and study the human brain. New technology increases the resolution of images that are being study as well as enables researchers to study the brain as it functions. These technological advances are combined with efforts to collect neuroimaging data on large numbers of subjects, in some cases longitudinally. This combination of advances in measurement and scope of studies requires novel development in the statistical analysis. Fast, scalable, robust and accurate models and approaches need to be developed to make headway on these problems. This volume represents a unique collection of researchers providing deep insights on the statistical analysis of big neuroimaging data.

This book provides in-depth information on Caatinga’s geographical boundaries and ecological systems, including plants, insects, fishes, amphibians, reptiles, birds, and mammals. It also discusses the major threats to the region’s socio-ecological systems and includes chapters on climate change and fast and large-scale land-use changes, as well as slow and small-scale changes, also known as chronic human disturbances. Subsequent chapters address sustainable agriculture, conservation systems, and sustainable development. Lastly, the book proposes 10 major actions that could enable the transformation of Caatinga into a place where people and nature can thrive together. “I consider this book an excellent example of how scientists worldwide can mobilize their efforts to propose sound solutions for one of the biggest challenges of modern times, i.e., how to protect the world’s natural ecosystems while improving human well-being. I am sure this book will inspire more research and conservation action in the region and perhaps encourage other groups of scientists to produce similar syntheses about their regions.” Russell Mittermeier, Ph.D. Executive Vice-Chair, Conservation International

Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

To document the world's diversity of species and reconstruct the tree of life we need to undertake some simple but mountainous tasks. Most importantly, we need to tackle species rich groups. We need to collect, name, and classify them, and then position them on the tree of life. We need to do this systematically across all groups of organisms and b

The past decade has witnessed an explosion of our knowledge on the structure, coding capacity and evolution of the genomes of the two DNA-containing cell organelles in plants: chloroplasts (plastids) and mitochondria. Comparative genomics analyses have provided new insights into the origin of organelles by endosymbioses and uncovered an enormous evolutionary dynamics of organellar genomes. In addition, they have greatly helped to clarify phylogenetic relationships, especially in algae and early land plants with limited morphological and anatomical diversity. This book, written by leading experts, summarizes our current knowledge about plastid and mitochondrial genomes in all major groups of algae and land plants. It also includes chapters on endosymbioses, plastid and mitochondrial mutants, gene expression profiling and methods for organelle transformation. The book is designed for students and researchers in plant molecular biology, taxonomy, biotechnology and evolutionary biology.

Providing a list of methods useful both to those who wish to study pseudogenes and to those who actually want to avoid their inadvertent detection, Pseudogenes: Functions and Protocols explores techniques involving pseudogenic DNA, RNA, and peptides/proteins, once believed to lack any functionality, but now known to be involved in complex regulatory circuits. After a few introductory chapters that overview the functions so far attributed to pseudogenes, this thorough volume delves into methods for pseudogene identification, for the detection of pseudogene transcription and translation, and for the study of the functions of pseudogenic RNA and proteins, as well as methods to avoid pseudogene detection when the focus of the research is their highly homologous parental counterparts. As part of the highly successful Methods in Molecular Biology series, chapters feature the kind of detailed descriptions and implementation advice that ensures successful results in the lab. Authoritative and practical, Pseudogenes: Functions and Protocols will contribute to the high interest of the scientific community toward pseudogenes, while stimulating the conception of pseudogene - centered research projects and providing experimental protocols that can facilitate their execution.
