Download or read book Evolutionary Innovations written by Matthew H. Nitecki and published by University of Chicago Press. This book was released on 1990-07-14 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary innovations—the bony skeleton of vertebrates, avian flight, or the insect pollination system of angiosperms, for example—have in recent years become the focus of much fertile new research in evolutionary biology. Innovations may hold the keys to understanding why whole new groups of organisms evolve or, conversely, why groups of organisms become extinct. This volume brings together contributors from the fields of morphology, genetics, embryology, physiology, and paleontology to present research on evolutionary innovations and to suggest directions for further work. The topics covered include the plurality of evolutionary innovations, patterns and processes at different hierarchical levels, evolutionary genetics of adaptations, heterochrony and other mechanisms of radical evolutionary change in early development, developmental mechanisms at the origin of morphological novelty, the evolution of morphological variation patterns, functional design and its punctuated products, plausibility and testability in assessing the consequences of evolutionary innovations, paradigms and pitfalls of studying physiological evolution, polyphyletic constructional breakthroughs in fossil and extant species, ecology of evolutionary innovations in the fossil record.

This title offers 50 papers presented at the sixth European Conferences on Echinoderms (ECE), covering population biology, biodiversity, anatomy and functional morphology, physiology and behavior, biological cycles, and resource potential. This book reflects the great diversity of its contributors, offering an opportunity to cover a broad range of important questions in a single, authoritative reference.
Download or read book Deep Sea Biology written by John D. Gage and published by Cambridge University Press. This book was released on 1991-04-18 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely volume provides a comprehensive account of the natural history of the organisms associated with the deep-sea floor and examines their relationship with this inhospitable environment--perhaps the most remote and least accessible location on the planet. The authors begin by describing the physical and chemical nature of the deep-sea floor and the methods used to collect and study its fauna. Then they discuss the ecology of the deep sea by exploring spatial patterns, diversity, biomass, vertical zonation, and large-scale distribution of organisms. Subsequent chapters review current knowledge of feeding, respiration, reproduction, and growth processes in these communities. The unique fauna of hypothermal vents and seeps are considered separately. Finally, there is a pertinent discussion of human exploitation of deep-sea resources and potential use of this environment for waste disposal.
Download or read book Fossil Crinoids written by Hans Hess and published by Cambridge University Press. This book was released on 2002 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crinoids have graced the oceans for more than 500 million years. Among the most attractive fossils, crinoids had a key role in the ecology of marine communities through much of the fossil record, and their remains are prominent rock forming constituents of many limestones. This is the first comprehensive volume to bring together their form and function, classification, evolutionary history, occurrence, preservation and ecology. The main part of the book is devoted to assemblages of intact fossil crinoids, which are described in their geological setting in twenty-three chapters ranging from the Ordovician to the Tertiary. The final chapter deals with living sea lilies and feather stars. The volume is exquisitely illustrated with abundant photographs and line drawings of crinoids from sites around the world. This authoritative account recreates a fascinating picture of fossil crinoids for paleontologists, geologists, evolutionary and marine biologists, ecologists and amateur fossil collectors.

Australian Echinoderms is an authoritative account of Australia’s 110 families of echinoderms. It brings together in a single volume comprehensive information on the identification, biology, evolution, ecology and management of these animals for the first time. Richly illustrated with beautiful photographs and written in an accessible style, Australian Echinoderms suits the needs of marine enthusiasts, academics and fisheries managers both in Australia and other geographical areas where echinoderms are studied.
Download or read book Causes of Evolution written by Robert M. Ross and published by University of Chicago Press. This book was released on 1990-12-18 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: By studying evolution across geological time, paleontologists gain a perspective that sometimes complements and sometimes conflicts with views based solely on studies of extant species. The contributors to Causes of Evolution consider whether factors exerting major influences on evolution are biotic or abiotic, intrinsic or extrinsic. Causes of Evolution presents a broad sampling of paleontological research programs encompassing vertebrates, invertebrates, and vascular plants; empirical work and theoretical models; organisms ranging in age from Cambrian to Recent; and temporal scales from ecological time to hundreds of millions of years. The diverse array of research styles and opinions presented will acquaint scientists in related fields with the strengths and weaknesses of paleontology as an approach to evolutionary studies and will give evolutionary biologists of every stripe new bases for evaluating the scope and bias of their own work.
Download or read book Life Traces of the Georgia Coast written by Anthony J. Martin and published by Indiana University Press. This book was released on 2013 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

Download or read book The Evolution and Fossil Record of Parasitism written by Kenneth De Baets and published by Springer Nature. This book was released on 2022-01-01 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume two focuses on the importance of direct host associations and host responses such as pathologies in the geological record to constrain the role of antagonistic interactions in driving the diversification and extinction of parasite-host relationships and disease. To better understand the impact on host populations, emphasis is given to arthropods, colonial metazoans, echinoderms, mollusks and vertebrates as hosts. In addition, novel techniques used to constrain interactions in deep time are discussed ranging from chemical and microscopic investigations of host remains, such as blood and coprolites, to the statistical inference of lateral transfer of transposons and host-parasite coevolutionary dynamics using molecular divergence time estimation.

This book was released on 2012-12-06 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword: "Predator-prey interactions are among the most significant of all organism-organism interactions....It will only be by compiling and evaluating data on predator-prey relations as they are recorded in the fossil record that we can hope to tease apart their role in the tangled web of evolutionary interaction over time. This volume, compiled by a group of expert specialists on the evidence of predator-prey interactions in the fossil record, is a pioneering effort to collate the information now accumulating in this important field. It will be a standard reference on which future study of one of the central dynamics of ecology as seen in the fossil record will be built." (Richard K. Bambach, Professor Emeritus, Virginia Tech, Associate of the Botanical Museum, Harvard University)
Download or read book Evolutionary Ecology of Marine Invertebrate Larvae written by Tyler J. Carrier and published by Oxford University Press. This book was released on 2018 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: "More than seventy percent of the earth's surface is covered by the ocean which is home to a staggering and sometimes overwhelming diversity of organisms, the majority of which reside in pelagic form. Marine invertebrate larvae are an integral component of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This accessible, upper-level text provides an important and timely update on the topic of larval evolution and ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content is structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; larval ecology in extreme and changing environments. This novel synthesis integrates traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research to provide a research and teaching tool for decades to come." -- from the rear cover.

Download or read book Nature written by Geerat Vermeij and published by Princeton University Press. This book was released on 2009-02-09 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: From humans to hermit crabs to deep water plankton, all living things compete for locally limiting resources. This universal truth unites three bodies of thought--economics, evolution, and history--that have developed largely in mutual isolation. Here, Geerat Vermeij undertakes a groundbreaking and provocative exploration of the facts and theories of biology, economics, and geology to show how processes common to all economic systems--competition, cooperation, adaptation, and feedback--govern evolution as surely as they do the human economy, and how historical patterns in both human and nonhuman evolution follow from this principle. Using a wealth of examples of evolutionary innovations, Vermeij argues that evolution and economics are one. Powerful consumers and producers exercise disproportionate controls on the characteristics, activities, and distribution of all life forms. Competition-driven demand by consumers, when coupled with supply-side conditions permitting economic growth, leads to adaptation and escalation among organisms. Although disruptions in production halt or reverse these processes temporarily, they amplify escalation in the long run to produce trends in all economic systems toward greater power, higher production rates, and a wider reach for economic systems and their strongest members. Despite our unprecedented power to shape our surroundings, we humans are subject to all the economic principles and historical trends that emerged at life's origin more than 3 billion years ago. Engagingly written, brilliantly argued, and sweeping in scope, Nature: An Economic History shows that the human institutions most likely to preserve opportunity and adaptability are, after all, built like successful living things.
