Book excerpt: This volume contains the proceedings of the NATO ARW on 'Biological Pattern Formation' held at Merton College, University of Oxford, on 27-31 August, 1992. The objective of the workshop was to bring together a select group of theoreticians and experimental biologists to present the latest results in the area of biological pattern formation and to foster interactiqn across dis- plines. The workshop was divided into 5 main areas: (i) limb development, (ii) Dictyostelium discoideum, (iii) Drosophila, (iv) cell movement, (v) g- eral pattern formation. We thank all the participants for their contributions, enthusiasm, and willingness to collaborate. There was a genuine, open, and extremely fru- ful interaction between the experimentalists and theoreticians which made the workshop a success. We also thank The Welcome Trust for providing additional funding. The local organization fell mainly on Denise McKittrick and Beverley Bhaskhare at the Mathematical Institute, Oxford, and Jeanette Hudson and the staff of Merton College. We greatly appreciate their help and patience. We also thank Jonathan Sherratt, Wendy Brandts and Debbie Benson for helping out in the conference and for providing a happy welcome to parti- pants on a typically cold, wet and windy English summer day.

Download or read book Biology of the Chemotactic Response written by Society for General Microbiology. Symposium and published by Cambridge University Press. This book was released on 1990 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tendency of a living organism to move to a more favourable environment is a natural but complex reaction, involving the integration of sometimes conflicting environmental stimuli as well as a coordinated mechanical response. The response of motile, single cell organisms to environmental stimuli provides a useful model for understanding first of all how the environment is monitored and sensed, and secondly how this information is processed to result in an integrated and coordinated response. The volume looks at a large number of well-studied examples of the chemotactic response, in prokaryotes and eukaryotes, and casts new light on how cells process information and react to their environment. This fundamental response is of great importance in understanding one of the characteristic features of living organisms.

Download or read book Cell to Cell Signalling written by A. Goldbeter and published by Academic Press. This book was released on 2014-06-28 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell to Cell Signalling: From Experiments to Theoretical Models is a collection of papers from a NATO Workshop conducted in Belgium in September 1988. The book discusses nerve cells and neural networks involved in signal transfers. The works of Hodgkin and Huxley presents a prototypic combination between experimental and theoretical approaches. The book discusses the coupling process found between secretory cells that modify their behavior. The text also analyzes morphogenesis and development, and then emphasizes the pattern formation found in Drosophila and in the amphibian embryo. The text also cite examples of immunological modeling that is related to the dynamics of immune networks based on idiotypic regulation. One paper analyzes the immune dynamism of HIV infection. The text notes that hormone signaling can be attributed as responsible for intercellular communication. Another paper examines how the dominant follicle in the ovarian cycle is selected, as well as the effectiveness of hormone secretion responsible for encoding the frequency of occurrence of periodic signals. The book also discusses heart signal sources such as cardiac dynamics and the response of periodically excited cardiac cells. The text can prove valuable for practioners in the field of neurology and cardiovascular medicine, and for researchers in molecular biology and molecular chemistry.
Download or read book Behavioral Mechanisms in Evolutionary Ecology written by Leslie Real and published by University of Chicago Press. This book was released on 1994-11-30 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book-length exploration of behavioral mechanisms in evolutionary ecology, this ambitious volume illuminates long-standing questions about cause-and-effect relations between an animal's behavior and its environment. By focusing on biological mechanisms—the sum of an animal's cognitive, neural, developmental, and hormonal processes—leading researchers demonstrate how the integrated study of animal physiology, cognitive processes, and social interaction can yield an enriched understanding of behavior. With studies of species ranging from insects to primates, the contributors examine how various animals identify and use environmental resources and deal with ecological constraints, as well as the roles of learning, communication, and cognitive aspects of social interaction in behavioral evolution. Taken together, the chapters demonstrate how the study of internal mechanistic foundations of behavior in relation to their ecological and evolutionary contexts and outcomes provides valuable insight into such behaviors as predation, mating, and dispersal. Behavioral Mechanisms in Evolutionary Ecology shows how a mechanistic approach unites various levels of biological organization to provide a broader understanding of the biological bases of behavioral evolution.

Available in PDF, EPUB and Kindle. Book excerpt: As a result of the molecular genetic analysis of development similar mechanisms for the regulation of gene expression are found in a wide range of organisms. In "Development - the Molecular Genetic Approach" these common mechanisms as well as the specific events leading to a differentiated cell are described. Particular items treated are, for example, how asymmetry is achieved, how cell size is determined, how cell division is controlled, how cell lineage influences development, how cells know their position, and how cells communicate during development.
Download or read book Nature Alive written by Adam Scarfe and published by Cambridge Scholars Publishing. This book was released on 2018-04-18 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume pays homage to Alfred North Whitehead’s (1861-1947) profound lecture and essay entitled “Nature Alive,” which was one of his most mature expressions of his process-relational metaphysics – a holistic conceptual framework that renders vivid the dynamic character of the natural world and the intrinsic purposiveness, selective agency, and creativity of living organisms. Inspired by, but not beholden to, Whitehead’s process metaphysical “lens,” the contributors to this volume bring a multiplicity of philosophical orientations to the table in challenging the mechanistic and reductionistic neo-Darwinian paradigm that is still dominant today in the life sciences. Mechanistic neo-Darwinism views nature and living organisms as “machines,” namely, as networks of externally related and linear causal “switches,” “dials,” “levers,” “pulleys,” and “gears,” that are “at the ready” for technological and biotechnological manipulation. Seeking a conceptual framework and a language that are more adequate to the study of the natural world and of living creatures than the mechanistic orientation, the contributors to this volume explore several of the “New Frontiers of Biology,” which are areas of biology whose findings to some extent go beyond the explanatory confines of the Modern Synthesis of natural selection and genetics. Most notably, emergence theory, the theory of organic selection, epigenetics, homeostasis, chronobiology, and autopoiesis research can provide us with key insights that can assist us in explaining how living agents emerged, including the evolutionary origins of mentality, consciousness, and mind. Moreover, attention to the “New Frontiers of Biology” can serve to “re-enchant” our understanding of the natural world and to prevent ecological devastation, through a restoration to objectivity of notions such as “intrinsic purposiveness,” “selective agency,” “creativity,” and “intrinsic value.”
Download or read book The Guanine Nucleotide Binding Proteins written by L. Bosch and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the EMBO-NATO-CEC Advanced Research Workshop on "Guanine-nucleotide binding proteins. Common structural and functional properties", which was held in Renesse, The Netherlands, August 6-11, 1988. The transmission of information is one of the most important processes in cellular life and involves the most diverse physiological functions. The cellular membrane, as the obligatory target for external signals, harbours complex pathways transducing the signals from the receptors of the external stimuli to the cytoplasmic effector. Heterotrimeric proteins are fundamental components of these pathways. Other proteins that are monomeric may be found associated with the membrane or in soluble form in the cytoplasm, and' can also function in signal transduction. Intracellular transmission of signals may proceed in an analogous fashion, protein synthesis being a well-known example. It is one of the most remarkable and puzzling observations of recent years that all of these proteins share common properties, both functionally and structurally. The ir primary structures show pronounced s imilari ties, in most cases concentrated in the NH2-terminal portion of the molecule. They all bind guanine nucleotides (hence the general name of G-proteins) and are GTPases, a crucial enzymatic activity, since it converts the active complex induced by GTP into the inactive one induced by GDP. Consensus sequences have been ident if ied as responsable for interact ing with the different parts of the guanine nucleotide.

Download or read book Emergent Forms written by Eugene Curtis Goldfield and published by Oxford University Press, USA. This book was released on 1995 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: While it is often assumed that behavioral development must be based upon both physical law and the biological principles of morphogenesis and selection, forging a link between these phenomena has remained an elusive goal. Now in Emergent Forms, psychologist Eugene C. Goldfield offers an exciting new theoretical framework--based, in part, on the concept of self-organization--that promises to aid researchers in their quest to discover the underlying origins and processes of behavioral development. Addressing the question of how familiar human functional acts--such as eating, walking, manipulating objects, and smiling--emerge during infancy, Goldfield proposes that during perceptually guided spontaneous activity a variety of biodynamic devices for doing different kinds of work are assembled and adapted to specific tasks. Throughout, the theory is examined in the context of development, and extended to atypical development and other domains, such as cognition and language. The author also addresses many long-standing issues in behavioral development, including the apparent disappearance of so-called primitive behaviors, the emergence of new skills, and the role of the caregiver in skill acquisition. The author concludes his work by discussing how the implications of this research can be applied to understanding abnormal development in children who are motor impaired. Interdisciplinary in scope and accessible to a broad range of readers, Emergent Forms will fascinate students and researchers of ecological, developmental, evolutionary, and cognitive psychology.
Download or read book Networks of Interacting Machines written by Dieter Armbruster and published by World Scientific. This book was released on 2005 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review volume is devoted to a discussion of analogies and differences of complex production systems OCo natural, as in biological cells, or man-made, as in economic systems or industrial production. Taking this unified look at production is based on two observations: Cells and many biological networks are complex production units that have evolved to solve production problems in a reliable and optimal way in a highly stochastic environment. On the other hand, industrial production is becoming increasingly complex and often hard to predict. As a result, modeling and control of such production networks involve many different spatial and temporal scales and decision policies for many different structures. The common themes of industrial and biological production include evolution and optimization, synchronization and self-organization, robust operation despite high stochasticity, and hierarchical dynamics. The mathematical techniques used come from dynamical systems theory, transport equations, control theory, pattern formation, graph theory, discrete event simulations, stochastic processes, and others. The application areas range from semiconductor production to supply chains, protein networks, slime molds, social networks, and whole economies."
