Early Development of the Shoulder Girdle and Sternum in Marsupials (Advances in Anatomy, Embryology and Cell Biology #109)
by Milan KlimaThe development of the breast-shoulder apparatus in the Marsupialia was inves tigated and compared with the conditions in Monotremata and Placentalia. The results were achieved by the investigation of material comprising altogether 109 histological serial sections of intrauterine embryos, neonates, and pouch young from 11 marsupial species. Additionally, 54 skeletons of subadult and adult marsupials from 25 species were included for comparison. The embryonic states show a strong similarity to the developmental stage of the breast-shoulder apparatus in the monotremes. In contrast, the adult breast-shoulder apparatus generally corresponds to that in placentals. The following elements can be observed in the marsupial breast-shoulder apparatus during embryogenesis: scapula, metacoracoid, procoracoid, first rib, paired sternal elements, unpaired sternal element, and clavicle. All the elements mentioned together form a compact, continuous arch in both the intrauterine embryos and the neonates. In the pouch young, this arch is reduced rather soon after birth, so that a compact connection between the left and the right half of the body no longer exists. All that remains is a loose connection via the clavicle. The metacoracoid becomes the processus coracoideus scapulae. The procoracoid becomes the praeclavium. The unpaired sternal element fuses with the paired sternal element, generating the uniform manubrium sterni. The first rib takes its usual position in the thorax. In the pouch young, the breast shoulder apparatus as a whole already shows all the typical characteristics that can be determined in adults.
Early Embryonic Development of Animals (Results and Problems in Cell Differentiation #18)
by Wolfgang HennigFour of the major animal systems studied for the mechanisms of their early embryonic development are treated in this volume. The articles address the specific questions studied in the various systems, discuss the fundamental questions raised by the particular organism and explain the techniques used to find answers to these questions. Questions of patternformation, early organogenesis and the genetics of the early development arecovered as well as the question of parental imprinting phenomena in mammals which are important for the early differentiation. The development of the mouse, Drosophila, Caenorhabditis and the zebrafish is emphasized by leading experts of their fields, and current problems in each system are exposed. For the zebrafish the advantages of this new system for developmental biology studies are summarized and discussed in their values, while in the other system the emphasis is laid on one of the actual field of research.
Early Evolution of Human Memory: Great Apes, Tool-making, and Cognition
by Héctor M. Manrique Michael J. WalkerThis work examines the cognitive capacity of great apes in order to better understand early man and the importance of memory in the evolutionary process. It synthesizes research from comparative cognition, neuroscience, primatology as well as lithic archaeology, reviewing findings on the cognitive ability of great apes to recognize the physical properties of an object and then determine the most effective way in which to manipulate it as a tool to achieve a specific goal. The authors argue that apes (Hominoidea) lack the human cognitive ability of imagining how to blend reality, which requires drawing on memory in order to envisage alternative future situations, and thereby modifying behavior determined by procedural memory. This book reviews neuroscientific findings on short-term working memory, long-term procedural memory, prospective memory, and imaginative forward thinking in relation to manual behavior. Since the manipulation of objects by Hominoidea in the wild (particularly in order to obtain food) is regarded as underlying the evolution of behavior in early Hominids, contrasts are highlighted between the former and the latter, especially the cognitive implications of ancient stone-tool preparation.
Early Evolutionary History of the Synapsida (Vertebrate Paleobiology and Paleoanthropology)
by Christian F. Kammerer Kenneth D. Angielczyk Jörg FröbischNon-mammalian synapsids were the dominant terrestrial vertebrates from the Late Carboniferous to the Middle Triassic and play a key role in understanding the origin and evolution of mammals. Despite these facts and the outstanding fossil record of the group, early synapsids remain obscure. This book showcases the full breadth of contemporary research on non-mammalian synapsids, ranging from taxonomy and phylogenetics to functional morphology, biogeography, paleoecology, and patterns of diversity. It also underscores the importance and potential of studying non-mammalian synapsid paleobiology in its own right, not just in the context of mammalian evolution.
Early Life History and Recruitment in Fish Populations (Fish & Fisheries Series #21)
by R. C. Chambers Edward A. TrippelMany of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.
Early Life History of Fish: An energetics approach (Fish & Fisheries Series #4)
by E. KamlerAmong the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold Antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air breathing in catfish and lungfish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are ofconsiderable importance to the survival ofthe human species in the form of nutritious and delicious food of numerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology, but an additional aim is for the books to be accessible to a wide spectrum ofnon specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Earth Matters on Stage: Ecology and Environment in American Theater (Routledge Studies in Theatre, Ecology, and Performance)
by Theresa J. MayEarth Matters on Stage: Ecology and Environment in American Theater tells the story of how American theater has shaped popular understandings of the environment throughout the twentieth century as it argues for theater’s potential power in the age of climate change. Using cultural and environmental history, seven chapters interrogate key moments in American theater and American environmentalism over the course of the twentieth century in the United States. It focuses, in particular, on how drama has represented environmental injustice and how inequality has become part of the American environmental landscape. As the first book-length ecocritical study of American theater, Earth Matters examines both familiar dramas and lesser-known grassroots plays in an effort to show that theater can be a powerful force for social change from frontier drama of the late nineteenth century to the eco-theater movement. This book argues that theater has always and already been part of the history of environmental ideas and action in the United States. Earth Matters also maps the rise of an ecocritical thought and eco-theater practice – what the author calls ecodramaturgy – showing how theater has informed environmental perceptions and policies. Through key plays and productions, it identifies strategies for artists who want their work to contribute to cultural transformation in the face of climate change.

The Earth Moved: On the Remarkable Achievements of Earthworms
by Amy Stewart"You know a book is good when you actually welcome one of those howling days of wind and sleet that makes going out next to impossible." —The New York Times In The Earth Moved, Amy Stewart takes us on a journey through the underground world and introduces us to one of its most amazing denizens. The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.
