This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation.

This volume includes treatments of systematics and related topics for both fungi and fungus-like organisms in four eukaryotic supergroups, as well as specialized chapters on nomenclature, techniques and evolution. These organisms are of great interest to mycologists, plant pathologists and others, including those interested in the animal parasitic Microsporidia. Our knowledge of the systematics and evolution of fungi has made great strides since the first edition of this volume, largely driven by molecular phylogenetic analyses. Consensus among mycologists has led to a stable systematic treatment that has since become widely adopted and is incorporated into this second edition, along with a great deal of new information on evolution and ecology. The systematic chapters cover occurrence, distribution, economic importance, morphology and ultrastructure, development of taxonomic theory, classification, and maintenance and culture. Other chapters deal with nomenclatural changes necessitated by revisions of the International Code of Nomenclature for algae, fungi and plants, including the elimination of separate names for asexual states, as well as methods for preservation of cultures and specimens, character evolution and methods for ultrastructural study, the fungal fossil record, and the impact of whole genomes on fungal studies.

This book represents a cutting-edge contribution giving an all-around perspective of eco-immunology today. Beside questions of the utmost importance for the whole community of immunologists, e.g, the intrinsic limits of immunological experiments performed at the bench on a limited number of selected models, the book covers several other facets of the eco-immunological approach, including host-parasite interactions, human aging and population immunology. Throughout the book the importance of population dynamics and evolutionary diversification of immune systems is frequently recalled, and makes the reader aware of the basic similarities and differences existing between humans and the models adopted for studying human immune system. The evidenced differences have been recently challenging the reliability of several established animal models and in the book it is discussed for the first time in analytical terms whether mice are reliable models of human inflammatory disorders.

Controversy over human evolution remains widespread. However, the human genome project and genetic sequencing of many other species have provided myriad precise and unambiguous genetic markers that establish our evolutionary relationships with other mammals. Human Evolution: Genes, Genealogies and Phylogenies identifies and explains these identifiable, rare and complex markers including endogenous retroviruses, genome-modifying transposable elements, gene-disabling mutations, segmental duplications and gene-enabling mutations. The new genetic tools also provide fascinating insights into when and how many features of human biology arose: from aspects of placental structure, vitamin C dependence and trichromatic vision, to tendencies to gout, cardiovascular disease and cancer. Bringing together a decade's worth of research and tying it together to provide an overwhelming argument for the mammalian ancestry of the human species, the book will be of interest to professional scientists and students in both the biological and biomedical sciences.

Species are not functionally independent. From a long-term perspective, only ecosystem with a fully integrated nutrient cycle is alive. The lack of trophic autonomy should be considered one of the key factors that ensure and maintain biodiversity. The variability of abiotic conditions, both in space and in time, also creates a huge diversity of niches and subniches for genotypes and species. In addition, life maintains its essential variables (biomass and productivity) as stable as possible due to the diversity of structures (genes, macromolecules, metabolic pathways, genotypes, species, etc.): the structures that reach optima are multiplied and thus activated, while the functioning of those which lost their optima is suppressed. The facts and concepts presented in this monograph thus support the conclusions that (a) genotype and species diversity is supported by trophic specialisation (b) biodiversity helps to stabilise the functions (essential variables) of individuals, populations, and ecological communities (c) in evolution, the emergence of biodiversity is determined by heritable variation and the advantage of specialised (more effective) structures over non-specialised ones (d) biodiversity is characterised by its ability to increase itself and to organise itself into relatively consistent structures, which we call production pyramids and nutrient cycles. This book therefore provides an answer to the question "why the diversity of life is of such and such a nature".

RNA viruses provide unique insights into the patterns and processes of evolutionary change in real time. The study of viral evolution is especially topical given the growing awareness that emerging and re-emerging diseases (most of which are caused by RNA viruses) represent a major threat to public health. However, while the study of viral evolution has developed rapidly in the last 30 years, relatively little attention has been directed toward linking work on the mechanisms of viral evolution within cells or individual hosts, to the epidemiological outcomes of these processes. This novel book fills this gap by considering the patterns and processes of viral evolution across their entire range of spatial and temporal scales. The Evolution and Emergence of RNA Viruses provides a comprehensive overview of RNA virus evolution, with a particular focus on genomic and phylogenetic approaches. This is the first book to link mechanisms of viral evolution with disease dynamics, using high-profile examples in emergence and evolution such as influenza, HIV, dengue fever, and rabies. It also reveals the underlying evolutionary processes by which emerging viruses cross species boundaries and spread in new hosts.

New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species. Detailed descriptions provide information about the paleobiology of this species, particularly with regards to how growth and development affected diet. Overall snout shape became progressively wider and more robust with age, suggesting that dietary shifts from juvenile to adult were not only a matter of size change, but of functional performance as well. These newly described elements provide additional characters upon which to base more robust phylogenetic analyses. The authors provide a revised diagnosis of this species, describing the new material and discussing incidents of apparent ontogenetic variation across the sampled population. The results of the ensuing phylogenetic analyses both situate Deltasuchus within an endemic clade of Appalachian crocodyliforms, separate and diagnosable from goniopholidids and pholidosaurs, herein referred to as Paluxysuchidae. This title is also available as Open Access on Cambridge Core.

When I first proposed a series entitled Current Mammalogy to the pub lishers, they were reluctant to undertake such a project because they viewed the field of mammology as overly fragmented. At first I found this idea to be difficult to accept; however, upon reflection, I came near to agreeing with it. Although many of us work on mammals, we gen erally feel more allegiance to our specialties, such as systematics, ge netics, cytogenetics, ecology, behavior, pest control, paleontology, wildlife management, primatology, and marine mammalogy, than we do to the general field of mammalogy. However, rather than becoming discour aged from pursuing this project, I became more certain than ever that a series such as Current Mammalogy was needed. We hope to make this series a place where specialists can present their ideas not only to other members of their specialty, but to those outside the area as well. Hopefully, this exchange of ideas will be a mutually beneficial exercise. The Editorial Board of Current Mammalogy has decided to keep the range of subjects in each volume as broad as possible rather than concentrating on one or two topics, in the hope that this will keep the series as useful as possible to the broadest range of readers."

Cellular-molecular approach to evolution has led to radical changes in our understanding of biologic principles ranging from the Cell, to the Life Cycle, Development, Homeostasis, Senescence/Aging, Heterochrony, Pleiotropy, Phenotype, and perhaps the purpose of life itself. Much of this new way of thinking about biology and medicine emanates from experimental evidence for epigenetic inheritance. This leads one to question whether our unicellular state is the actual primary level of selection. One particular system that is now recognized as being under the auspices of epigenetic inheritance is the endocrine system, which is conventionally thought to regulate physiologic homeostasis. However, because the sex hormones play such a major role in behaviors related to the acquisition of epigenetic data, and the processing of such epigenetic data by the gonads during meiosis, their role in the evolution of the organism become tractable. The composite of the activities of the individual over the course of its lifetime can now be understood causally, resulting from the orchestration of its physiology by hormones, prenatally, postnatally and during the aging process, across the entire life span of the organism. Specific behaviors over the course of the life cycle during childhood, adolescence, puberty, adulthood and aging can now be understood mechanistically rather than merely as milestones in the various stages of life. With the above considerations in mind, this book presents the cellular-evolutionary perspective towards the relationship of the organism with its surroundings, human and non-human alike renders biology and medicine a continuum instead of fragmented, un-related anecdotes.

Charles Darwin's "Historical Sketch" has appeared as a preface to nearly every authorized edition of Darwin's Origin of Species since the second English edition was published in 1860. The "Historical Sketch" provides a brief history of opinion about the species question as a prelude to Darwin's own independent contribution to the subject, but its provenance is somewhat obscure. While some previous thinkers anticipated portions of Darwin's theory long before he did, none of them saw the complete picture as clearly as Darwin. As such, he was able to claim originality and priority for the idea that has transformed our understanding of nature. His "Historical Sketch" was written as an attempt to address these issues. Some things are known about its production, such as when it first appeared and what changes were made to it between its first appearance in 1860 and its final form in 1866. Other questions remain unanswered. How did it evolve in Darwin's mind? Why did he write it at all? What did he think he was accomplishing by prefacing it to Origin of Species? Curtis Johnson approaches these questions, offering some clarity on the originality of Darwin's work. Darwin's "Historical Sketch" is the first comprehensive study of Darwin's "Preface" to Origin of Species. Johnson conveys the pressure Darwin felt from friends and other correspondents to showcase the originality of his theory, and he tackles questions of originality by carefully examining the 35 authors Darwin referenced in this monumental text.

This book answers the question "What is it that viruses do?" by presenting three aspects of viral ecology. The first aspect explains how viruses affect the population diversity and energetics of their host communities. Perhaps the most notable example of this concept is our understanding that primary production within ecosystems often depends upon those viruses which serve as controllers of nutrient recycling, connecting the aquatic and terrestrial realms in ways that can be assessed locally and globally. The second aspect describes genetic partnerships which exist between hosts and their viruses. These include processes termed endogeny and lysogeny by which the host carries at least a partial genomic copy of the virus. Fluidity of these collective genomes is expressed on an evolutionary time scale and the mutual life cycles which they produce represent a forging of shared genomic fate that obligates partnership of the virus and its host. The viral sequences represent a source of potential benefit as well as potential peril for the host and can implement phenotypic changes in the host. Hosts often use those changes as tools. As humans, the most notable example would be that mammals rely upon temporary activation of their endogenous viral genes in order to successfully develop a placenta. The third aspect is defending the health of a host, which relies upon activity in two directions. Hosts often use their captured viral genes to identify and subsequently direct battle against invading viruses. This natural concept has been engineered for combating cancer, is useful for suppressing the detrimental consequences of genetic diseases, and has been developed to create targeted antiviral vaccines. But, the defense has to work in two directions and the host can use other symbiotic microorganisms as protection against its viruses. This book will appeal to a wide readership by providing a broad perspective of viral ecology, and all scientists will find it helpful for gaining a view of fields beyond their specialization.

The epistemological synthesis of the various theories of evolution, since the first formulation in 1802 with the transmission of the inherited characters by J.B. Lamarck, shows the need for an alternative synthesis to that of Princeton (1947). This new synthesis integrates the scientific models of self-organization developed during the second half of the 20th century based on the laws of physics, thermodynamics, and mathematics with the emergent evolutionary problematics such as self-organized memory. This book shows, how self-organization is integrated in modern evolutionary biology. It is divided in two parts: The first part pays attention to the modern observations in paleontology and biology, which include major theoreticians of the self-organization (d'Arcy Thompson, Henri Bergson, Rene Thom, Ilya Prigogine). The second part presents different emergent evolutionary models including the sciences of complexity, the non-linear dynamical systems, fractals, attractors, epigenesis, systemics, and mesology with different examples of the sciences of complexity and self-organization as observed in the human lineage, from both internal (embryogenesis-morphogenesis) and external (mesology) viewpoints.

The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

This book presents a detailed examination of the current state of knowledge in the field of paleoneurology in the main amniote groups (reptiles, birds and mammals), and advances resulting from new non-invasive technologies. The study of fossil endocasts is an area of considerable current interest, and has long been central to our understanding of the evolution of the brain, development of senses and behavioral adaptations in diverse vertebrate groups and across vertebrates as a whole. Recent advances in non-invasive imaging have significantly increased the number of fossil taxa for which brain morphology is known, and it may now be possible to quantitatively analyze the relative size of brain regions. Providing a general overview of current perspectives and problems in evolutionary neuroanatomy, this book is intended for a wide range of readers, including undergraduate and graduate students, teachers, and anyone with a special interest in paleoneurology. It is also useful as supplementary reading for courses in digital anatomy, vertebrate comparative anatomy, computed morphometrics, paleontology, neurology and radiology as well as evolution programs

Widely seen as evolution's founding figure, Charles Darwin is taken by many evolutionists to be the first to propose a truly modern theory of evolution. Darwin's greatness, however, has obscured the man and his work, at times even to the point of distortion. Accessibly written, this book presents a more nuanced picture and invites us to discover some neglected ambiguities and contradictions in Darwin's masterwork. Delisle and Tierney show Darwin to be a man who struggled to reconcile the received wisdom of an unchanging natural world with his new ideas about evolution. Arguing that Darwin was unable to break free entirely from his contemporaries' more traditional outlook, they show his theory to be a fascinating compromise between old and new. Rediscovering this other Darwin - and this other side of On the Origin of Species - helps shed new light on the immensity of the task that lay before 19th century scholars, as well as their ultimate achievements.

This book discusses the history of invertebrate fossil understanding and classification by exploring fossil studies between the 15th and 18th centuries. Before the modern age, the understanding of fossil findings went through several phases. The treatment by philologists, philosophers and historians of natural sciences involved religious, sometimes folkloristic, aspects before scientific ones. This work showcases and assesses these original findings by carrying out a bibliographical, and above all iconographical research, aimed at finding the first printed images of the objects that we now know as fossils. From here, the authors provide an understanding of the true nature of fossils by analyzing them through modern academic viewpoints, and describing each fossil group from a paleontological and taxonomic point of view, retracing their treatment in the course of the centuries. As a point of reference for each fossil group treated, the authors have considered indispensable the use of ancient prints as evidence of the first iconographic sources dedicated to fossils, starting from those in the late fifteenth century, dedicated to the most common groups of invertebrates without neglecting a necessary exception, the ichthyodontolites, fundamental in the discussion in Italy on the interpretation of the organic origin of fossils, and from the end of the sixteenth century to about half of the eighteenth century. The abundant iconographic apparatus used, often unpublished or specially reworked, is essential and functional to the understanding of the various aspects addressed, a visual complement to the text and vice versa, designed and used taking its cue from the need imposed on early scholars to document their discoveries visually. Among the chosen images there is no shortage of original attributions to fossil finds that have been poorly understood or misidentified until now. The English translation of this book from its Italian original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the authors.

The four volumes of Game Equilibrium Models present applications of non-cooperative game theory. Problems of strategic interaction arising in biology, economics, political science and the social sciences in general are treated in 42 papers on a wide variety of subjects. Internationally known authors with backgrounds in various disciplines have contributed original research. The reader finds innovative modelling combined with advanced methods of analysis. The four volumes are the outcome of a research year at the Center for Interdisciplinary Studies of the University of Bielefeld. The close interaction of an international interdisciplinary group of researchers has produced an unusual collection of remarkable results of great interes for everybody who wants to be informed on the scope, potential, and future direction of work in applied game theory. Volume I Evolution and Game Dynamics mainly deals with dynamic stability with respect to evolutionary processes. The book offers not only theoretical classification of the foundations of evolutionary game theory, but also exciting new biological applications. Volume II Methods, Morals and Markets contains areas of research which will attract the interest of economists, political scientists, mathematicians and philosophers. The papers deal with the methodology of analysis of games, game theoretic contributions to fundamental ethical questions facing societies and game-theoretic analyses of market environments. Volume III Strategic Bargaining contains ten papers on game equilibrium models of bargaining. All these contributions look at bargaining situations as non-cooperative games. General models of two-person and n-person bargaining areexplored. Volume IV Social and Political Interaction contains game equilibrium models focussing on social and political interaction within communities or states or between states, i.e. national and international social and political interaction. Specific aspects of those interactions are modelled as non-cooperative games and their equilibria are analysed.

Epigenetic modifications comprise heritable gene expression changes that occur without alteration of the DNA sequence and 'co-act' with genetic factors to shape development processes and evolutionary trajectories. Multicellular organisms receive different types of environmental stimuli/stresses that trigger epigenetic modifications during development. These environmentally driven mechanisms represent an underlying cause of phenotypic diversity, especially in metazoans. This book aims to present some of the latest epigenetic insights into the development of metazoans (including humans) as an intersection between their ecology and evolution.

The Wrong Ape for Early Human Origins examines ways in which the chimpanzee referential model has exerted a primary influence on evolutionary theory, dominating portraits of proto- and early human social life, and in the broader sense, of human nature itself. Evidence on which this model is based is revisited, along with new cross-disciplinary findings that point to alternative scenarios for hominin phylogeny, ecology and subsistence, primeval kinship, cognition and language, and the respective roles played by aggression and cooperation as evolutionary drivers. Recent advances in phylogenetics, evolutionary biology, and new additions to the fossil record are rendering linear, monotypic models obsolete. Contemporary theories on species divergence and change over time are shifting attention from ancient genotypes to factors that influence gene expression, and from innate prescriptive behaviors to epigenesis and the capacity for behavioral plasticity. This broader platform has the potential to fundamentally revise current notions about the basic nature, phenotypic traits, and lifeways of ancestral humans. It informs a different profile of our progenitors—one that reflects greater ecological bandwidth, reliance on creative niche construction, and hominin agency in the structuring of ancient reproductive and social groups.

This book introduces the value of a Darwinian social evolutionary approach to understanding social change. The chapters discuss several different perspectives on social evolutionary theory, and go on to link these with comparative and historical sociological theory, and two case-studies. Kerr brings together social change theory and theories on nationalism, whilst also providing concrete examples of the theories at work. The book offers a vision of rapprochement between these different areas of theory and study, and to where this could lead future studies of comparative history and sociology. As such, it should be useful to scholars and students of nationalism and social change, sociologists, political scientist and historians.
