One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

This authored book assesses the spatial patterns of climate change and gender inequalities across the Global South, and analyzes the disproportionate impacts that climate change processes have on women in these regions. Though many books attempt to incorporate gender issues into climate change, this book examines the issue as a whole by addressing the relationship between climate change and gender from a number of perspectives. The book incorporates case studies from various regions of the Global South, a designation broadly defined as the countries of Africa, Middle and South America, and most of Asia including the Middle East. In the book's two main sections, readers will learn about how climate change affects access to regional opportunities and resources, the obstacles created by climate change that affect women more strongly than men, and how affected female populations adapt to changing conditions and protect their local livelihoods. Section one, covering chapters 1 and 2, addresses the spatial patterns of climate change and gender inequalities/inequities across the Global South by analyzing long-term trends from the latest reports of the Intergovernmental Panel on Climate Change (IPCC) and the World Economic forum. Section two, covering chapters 3 through 7, discusses the critical issues related to climate change and gender inequality, and presents literature reviews and case studies in the Global South. The different issues and perspectives discussed include health, water and food security, education, conflicts, migration, participation in decision-making processes, and changing urban social landscapes. The concluding chapter discusses policy initiatives and makes recommendations to some of the gender mainstreaming through empowerment and participation. This interdisciplinary book will appeal to academics and policy-makers beyond just the fields of environmental sciences and gender studies, and may be adopted as a resource for graduate students and researchers.

This multi-author, six-volume work summarizes our current knowledge on the developmental biology of all major invertebrate animal phyla. The main aspects of cleavage, embryogenesis, organogenesis and gene expression are discussed in an evolutionary framework. Each chapter presents an in-depth yet concise overview of both classical and recent literature, supplemented by numerous color illustrations and micrographs of a given animal group. The largely taxon-based chapters are supplemented by essays on topical aspects relevant to modern-day EvoDevo research such as regeneration, embryos in the fossil record, homology in the age of genomics and the role of EvoDevo in the context of reconstructing evolutionary and phylogenetic scenarios. A list of open questions at the end of each chapter may serve as a source of inspiration for the next generation of EvoDevo scientists. Evolutionary Developmental Biology of Invertebrates is a must-have for any scientist, teacher or student interested in developmental and evolutionary biology as well as in general invertebrate zoology. This volume starts off with three chapters that set the stage for the entire work by covering general aspects of EvoDevo research, including its relevance for animal phylogeny, homology issues in the age of developmental genomics, and embryological data in the fossil record. These are followed by taxon-based chapters on the animals that are commonly considered to have branched off the Animal Tree of Life before the evolution of the Bilateria: the Porifera, Placozoa, Cnidaria (with the Myxozoa being treated separately) and Ctenophora. In addition, the Acoelomorpha, Xenoturbellida and Chaetognatha are examined, including their currently hotly debated phylogenetic affinities.

The main focus of this book entitled is to provide an up-to-date coverage of marine sponges and their significance in the current era. This book is an attempt to compile an outline of marine sponge research to date, with specific detail on these bioactive compounds, and their pharmacological and biomedical applications. The book encompasses twenty chapters covering various topics related to Marine Sponges. Initial couple of chapters deal about the worldwide status of marine sponge research, the recent findings regarding dynamics of sponges, and several interesting research areas, that are believed to be deserving of increased attention. Variety of sponges, their toxicology, metagenomics, pharmaceutical significance and their possible applications in biomedicine has been discussed in detail. The second half of this part includes chapters on chemical ecology of marine sponges followed by the discussion on importance of bioeroding sponges in aquaculture systems. The following four chapters of the book deal majorly with the chemical molecules of marine sponges. In the fifth chapter, marine sponge-associated actinobacteria and their pysicochemical properties have been discussed followed by their bioactive potential. The biological application of marine sponges has been presented in later chapters with the classification of biologically active compounds being explored in detail. The second half of the book presents the vast repertoire of secondary metabolites from marine sponges, which include terpenoids, heterocycles, acetylenic compounds, steroids and nucleosides. Further, the bioactive potential of these compounds has also been discussed. One of the constituent chapter elaborates the bioactive alkaloids from marine sponges namely, pyridoacridine, indole, isoquinolene, piperidene, quinolizidine, steroidal and bromotyrosine alkaloids isolated from them. In the next couple of chapters, important sponge polymers and the anticancer effects of marine sponge compounds have been presented. The most interesting aspect of sponge biology is their use in biomedical arena. An effort has been made in this book, to cover the major constituents of sponges and their biomedical potentials. The major portion of sponge body is composed of collagen and silica and used in tissue engineering as scaffold material. This part of the book compiles chapters delineating the isolation of sponge biomaterials including collagen and their use in medical diagnostics. Overall, this book would be an important read for novice and experts in the field of sponge biology.

This book summarizes the latest advances in sponge science through a concise selection of studies presented at the VIII World Sponge Conference. The collection of articles reflects hot, ongoing debates in molecular research, such as the monophyletic versus paraphyletic nature of the sponge group, or the new awareness on pros and cons of standard barcodes and other markers in sponge taxonomy and phylogeny. It also features articles showing how the new sequencing technologies reveal the functional and phylogenetic complexity of the "microbial universe" associated to sponge tissues. The ecological interactions of sponges, the effects of nutrients and pollutants, the variability in reproductive patterns, and the processes generating genotypic and phenotypic variability in sponge populations are covered in several contributions. Zoogeography, population structure and dynamics are also approached with both traditional and molecular tools. The effect of anthropogenic disturbance on the natural environment finds its place in this volume with papers dealing with metal accumulation and the potential role of sponges as biomonitors. Biodiversity data from unexplored tropical and deep sea areas are presented. We hope readers will enjoy the selection of papers, which we believe represent collectively a significant contribution to our current understanding of sponges.

Understanding Human Anatomy and Pathology: An Evolutionary and Developmental Guide for Medical Students provides medical students with a much easier and more comprehensive way to learn and understand human gross anatomy by combining state-of-the-art knowledge about human anatomy, evolution, development, and pathology in one book. The book adds evolutionary, pathological, and developmental information in a way that reduces the difficulty and total time spent learning gross anatomy by making learning more logical and systematic. It also synthesizes data that would normally be available for students only by consulting several books at a time. Anatomical illustrations are carefully selected to follow the style of those seen in human anatomical atlases but are simpler in their overall configuration, making them easier to understand without overwhelming students with visual information. The book’s organization is also more versatile than most human anatomy texts so that students can refer to different sections according to their own learning styles. Because it is relatively short in length and easily transportable, students can take this invaluable book anywhere and use it to understand most of the structures they need to learn for any gross anatomy course.

From medieval bestiaries to Borges’s Book of Imaginary Beings, we’ve long been enchanted by extraordinary animals, be they terrifying three-headed dogs or asps impervious to a snake charmer’s song. But bestiaries are more than just zany zoology—they are artful attempts to convey broader beliefs about human beings and the natural order. Today, we no longer fear sea monsters or banshees. But from the infamous honey badger to the giant squid, animals continue to captivate us with the things they can do and the things they cannot, what we know about them and what we don’t. With The Book of Barely Imagined Beings, Caspar Henderson offers readers a fascinating, beautifully produced modern-day menagerie. But whereas medieval bestiaries were often based on folklore and myth, the creatures that abound in Henderson’s book—from the axolotl to the zebrafish—are, with one exception, very much with us, albeit sometimes in depleted numbers. The Book of Barely Imagined Beings transports readers to a world of real creatures that seem as if they should be made up—that are somehow more astonishing than anything we might have imagined. The yeti crab, for example, uses its furry claws to farm the bacteria on which it feeds. The waterbear, meanwhile, is among nature’s “extreme survivors,” able to withstand a week unprotected in outer space. These and other strange and surprising species invite readers to reflect on what we value—or fail to value—and what we might change. A powerful combination of wit, cutting-edge natural history, and philosophical meditation, The Book of Barely Imagined Beings is an infectious and inspiring celebration of the sheer ingenuity and variety of life in a time of crisis and change.
