Available in PDF, EPUB and Kindle. Book excerpt: Hypothesis testing is not a straightforward matter in the fossil record and here, too interactions with biology can be extremely profitable. Quite simply, predictions regarding long-term consequences of processes observed in liv ing organisms can be tested directly using paleontological data if those liv ing organisms have an adequate fossil record, thus avoiding the pitfalls of extrapolative approaches. We hope to see a burgeoning of this interactive effort in the coming years. Framing and testing of hypotheses in paleon tological subjects inevitably raises the problem of inferring process from pattern, and the consideration and elimination of a broad range of rival hy is an essential procedure here. In a historical science such as potheses paleontology, the problem often arises that the events that are of most in terest are unique in the history of life. For example, replication of the metazoan radiation at the beginning of the Cambrian is not feasible. How ever, decomposition of such problems into component hypotheses may at least in part alleviate this difficulty. For example, hypotheses built upon the role of species packing might be tested by comparing evolutionary dy namics (both morphological and taxonomic) during another global diversi fication, such as the biotic rebound from the end-Permian extinction, which removed perhaps 95% of the marine species (see Valentine, this volume). The subject of extinction, and mass extinction in particular, has become important in both paleobiology and biology.

Download or read book Mites written by Marilyn A. Houck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many mites possess extremely intricate life styles in close association with plant and animal hosts. Their polymorphism has made classification a challenge, and their ability to reproduce both sexually and asexually has made efforts to control their populations difficult. This, however, has given rise to theories to explain the origin and function of sexual reproduction in general. In numbers of species and geographic distribution, mites may even surpass the insects. In soils, they are a major component in the system for cycling nutrients. Unlike insects, they have invaded the marine environment. These and a number of other topics are explored in Mites. Because of their extremely small size, mites have been ignored during the development of major evolutionary and ecological theories. Yet mites routinely violate fundamental concepts such as heterochrony, sexual selection, the evolution of sex ratio, and ontogeny. Recent research methodologies have made it practical for the first time to perform experimental work with mites, and since they offer short generation times and rapid research results, they are excellent model systems. Mites announces these results and should appeal to professionals in entomology, acarology, ecology, population genetics, and evolutionary biology.
Download or read book A Primer of Life Histories written by Jeffrey A. Hutchings and published by Oxford University Press. This book was released on 2021-09-15 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.
Download or read book Adventures in the Anthropocene written by Gaia Vince and published by Milkweed Editions. This book was released on 2014-10-20 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: A science journalist travels the world to explore humanity’s ecological devastation—and its potential for renewal in this “compelling read” (Guardian, UK). We live in times of profound environmental change. According to a growing scientific consensus, the dramatic results of man-made climate change have ushered the world into a new geological era: the Anthropocene, or Age of Man. As an editor at Nature, Gaia Vince couldn’t help but wonder if the greatest cause of this dramatic planetary change—humans’ singular ability to adapt and innovate—might also hold the key to our survival. To investigate this provocative question, Vince travelled the world in search of ordinary people making extraordinary changes to the way they live—and, in many cases, finding new ways to thrive. From Nepal to Patagonia and beyond, Vince journeys into mountains and deserts, forests and farmlands, to get an up close and personal view of our changing environment. Part science journal, part travelogue, Adventures in the Anthropocene recounts Vince’s journey, and introduces an essential new perspective on the future of life on Earth.
Download or read book Mechanisms of Life History Evolution written by Thomas Flatt and published by OUP Oxford. This book was released on 2011-05-12 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).

Download or read book Life History Evolution in Plants written by Timo Olavi Vuorisalo and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The lack of discussion of the life histories of modular organisms is the weakness of this book that I most regret. . . . Modular organisms are different. " S. C. Steams: The Evolution of Life Histories (1992) Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance for evolutionary success, much work has also been conducted on patterns of development, growth and senescence, as well as on the shifts in resource allocation related to these processes. The basic axiom of life-history theory is that patterns of life histories, such as reproductive traits, are subject to evolutionary explanation. This idea can be traced back at least as far as Darwin's Origin of Species (1859). In his discussion of plant domestication, Darwin wrote: "I cannot doubt that the continued selection of slight variations, either in the leaves, the flowers, or the fruit, will produce races differing from each other chiefly in these characters". Darwin was impressed by the success of plant breeders in moulding the growth and reproductive parameters of cultivated plants, and believed that natural selection could have a similar impact in natural populations.
Download or read book Primate Life Histories and Socioecology written by Peter M. Kappeler and published by University of Chicago Press. This book was released on 2003-02 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: We know a great deal about roles the environment plays in shaping survival, reproductive success, and even social systems among primates. But how do primate life histories affect social systems and vice versa? Do baboons' patterns of growth, for example, help to structure their societies? Does fission-fusion sociality interact with predator pressure to influence the timing of maturation in chimpanzees? Exploring these issues and many others, the contributors to Primate Life Histories and Socioecology provide the first systematic attempt to understand relationships among primate life histories, ecology, and social behavior conjointly. Topics covered include how primate life histories interact with rates of evolution, predator pressure, and diverse social structures; how the slow maturation of primates affects the behavior of both young and adult caregivers; and reciprocal relationships between large brains and increased social and behavioral complexity. The first collection of its kind, this book will interest a wide range of researchers, from anthropologists and evolutionary biologists to psychologists and ecologists.

Download or read book Animal Body Size written by Felisa A. Smith and published by University of Chicago Press. This book was released on 2013-08-09 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galileo wrote that “nature cannot produce a horse as large as twenty ordinary horses or a giant ten times taller than an ordinary man unless by miracle or by greatly altering the proportions of his limbs and especially of his bones”—a statement that wonderfully captures a long-standing scientific fascination with body size. Why are organisms the size that they are? And what determines their optimum size? This volume explores animal body size from a macroecological perspective, examining species, populations, and other large groups of animals in order to uncover the patterns and causal mechanisms of body size throughout time and across the globe. The chapters represent diverse scientific perspectives and are divided into two sections. The first includes chapters on insects, snails, birds, bats, and terrestrial mammals and discusses the body size patterns of these various organisms. The second examines some of the factors behind, and consequences of, body size patterns and includes chapters on community assembly, body mass distribution, life history, and the influence of flight on body size.
Download or read book Life History Evolution written by Derek A. Roff and published by Sinauer Associates Incorporated. This book was released on 2002 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life History Evolution represents a synthetic approach to the understanding of the evolution of life history variation using the three types of environment (constant, stochastic, predictable) as the focus under which the theory is developed and tested. First, the author outlines a general framework for the study and analysis of life history variation, bringing together the approaches of quantitative genetic modeling and optimality analysis. Using this framework, he then discusses how life histories evolve in the three different types of environments, each of which presents unique characteristics. The theme of the book is that an understanding of evolutionary change requires analysis at both the genetic and phenotypic levels, and that the environment plays a central role in such analyses. Intended for graduate students and researchers, the book's emphasis is on assumptions and testing of models. Mathematical processes are described, but mathematical derivations are kept to a minimum. Each chapter includes a summary, and boxes provide supplementary material.
