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.
Download or read book Niche Evolution and Phylogenetic Community Paleoecology of Late Ordovician Crinoids written by Selina R. Cole and published by Cambridge University Press. This book was released on 2022-05-26 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician). Patterns of community structure and niche evolution are evaluated over a ~5 million-year period through comparison with the Brechin Lagerstätte (Katian, Upper Ordovician). The authors establish filtration fan density, food size selectivity, and body size as major axes defining niche differentiation, and niche occupation is strongly controlled by phylogeny. Ecological strategies were relatively static over the study interval at high taxonomic scales, but niche differentiation and specialization increased in most subclades. Changes in disparity and species richness indicate the transition between the early-middle Paleozoic Crinoid Evolutionary Faunas was already underway by the Katian due to ecological drivers and was not triggered by the Late Ordovician mass extinction.

Download or read book Echinoderm Morphological Disparity Methods Patterns and Possibilities written by Bradley Deline and published by Cambridge University Press. This book was released on 2021-02-11 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantification of morphology through time is a vital tool in elucidating macroevolutionary patterns. Studies of disparity require intense effort but can provide insights beyond those gained using other methodologies. Over the last several decades, studies of disparity have proliferated, often using echinoderms as a model organism. Echinoderms have been used to study the methodology of disparity analyses and potential biases as well as documenting the morphological patterns observed in clades through time. Combining morphological studies with phylogenetic analyses or other disparate data sets allows for the testing of detailed and far-reaching evolutionary hypotheses.
Download or read book Foundations of Macroecology written by Felisa A. Smith and published by University of Chicago Press. This book was released on 2014-08-22 with total page 817 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroecology is an approach to science that emphasizes the description and explanation of patterns and processes at large spatial and temporal scales. Some scientists liken it to seeing the forest through the trees, giving the proverbial phrase an ecological twist. The term itself was first introduced to the modern literature by James H. Brown and Brian A. Maurer in a 1989 paper, and it is Brown’s classic 1995 study, Macroecology, that is credited with inspiring the broad-scale subfield of ecology. But as with all subfields, many modern-day elements of macroecology are implicit in earlier works dating back decades, even centuries. Foundations of Macroecology charts the evolutionary trajectory of these concepts—from the species-area relationship and the latitudinal gradient of species richness to the relationship between body size and metabolic rate—through forty-six landmark papers originally published between 1920 and 1998. Divided into two parts—“Macroecology before Macroecology” and “Dimensions of Macroecology”—the collection also takes the long view, with each paper accompanied by an original commentary from a contemporary expert in the field that places it in a broader context and explains its foundational role. Providing a solid, coherent assessment of the history, current state, and potential future of the field, Foundations of Macroecology will be an essential text for students and teachers of ecology alike.
Download or read book Palaeogeography and Palaeobiogeography Biodiversity in Space and Time written by Paul Upchurch and published by CRC Press. This book was released on 2011-10-24 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeography represents one of the most complex and challenging aspects of macroevolutionary research, requiring input from both the earth and life sciences. Palaeogeographic reconstruction is frequently carried out by researchers with backgrounds in geology and palaeontology, who are less likely to be familiar with the latest biogeographic techniques: conversely, biogeographic methods are often devised by neontologists who may be less familiar with the fossil record, stratigraphy, and palaeogeography. Palaeogeography and Palaeobiogeography: Biodiversity in Space and Time bridges the gap between these two communities of researchers, who work on the same issues but typically use different types of data. The book covers a range of topics, and reflects some of the major overall questions in the field such as: Which approaches are best suited to reconstructing biogeographic histories under a range of circumstances? How do we maximize the use of organismal and earth sciences data to improve our understanding of events in earth history? How well do analytical techniques devised for researching the biogeography of extant organisms perform in the fossil record? Can alternative biodiversity metrics, particularly those based on morphological measurements, enhance our understanding of biogeographic patterns and processes? This book approaches palaeobiogeography with coverage of technological applications and detailed case studies. It spans a wide selection of overlapping and integrative disciplines, including evolutionary theory, vicariance biogeography, extinctions, and the philosophical aspects of palaeogeography. It also highlights new technological innovations and applications for research. Presenting a unique discussion of both palaeogeography and palaeobiogeography in one volume, this book focuses both historically and philosophically on the interface between geology, climate, and organismal distribution.

Available in PDF, EPUB and Kindle. Book excerpt: "In a book both beautifully illustrated and deeply informative, Jonathan Losos, a leader in evolutionary ecology, celebrates and analyzes the diversity of the natural world that the fascinating anoline lizards epitomize. Readers who are drawn to nature by its beauty or its intellectual challenges—or both—will find his book rewarding."—Douglas J. Futuyma, State University of New York, Stony Brook "This book is destined to become a classic. It is scholarly, informative, stimulating, and highly readable, and will inspire a generation of students."—Peter R. Grant, author of How and Why Species Multiply: The Radiation of Darwin's Finches "Anoline lizards experienced a spectacular adaptive radiation in the dynamic landscape of the Caribbean islands. The radiation has extended over a long period of time and has featured separate radiations on the larger islands. Losos, the leading active student of these lizards, presents an integrated and synthetic overview, summarizing the enormous and multidimensional research literature. This engaging book makes a wonderful example of an adaptive radiation accessible to all, and the lavish illustrations, especially the photographs, make the anoles come alive in one's mind."—David Wake, University of California, Berkeley "This magnificent book is a celebration and synthesis of one of the most eventful adaptive radiations known. With disarming prose and personal narrative Jonathan Losos shows how an obsession, beginning at age ten, became a methodology and a research plan that, together with studies by colleagues and predecessors, culminated in many of the principles we now regard as true about the origins and maintenance of biodiversity. This work combines rigorous analysis and glorious natural history in a unique volume that stands with books by the Grants on Darwin's finches among the most informed and engaging accounts ever written on the evolution of a group of organisms in nature."—Dolph Schluter, author of The Ecology of Adaptive Radiation

Download or read book Evolutionary Developmental Biology written by Brian K. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although evolutionary developmental biology is a new field, its origins lie in the last century; the search for connections between embryonic development (ontogeny) and evolutionary change (phylogeny) has been a long one. Evolutionary developmental biology is however more than just a fusion of the fields of developmental and evolutionary biology. It forges a unification of genomic, developmental, organismal, population and natural selection approaches to evolutionary change. It is concerned with how developmental processes evolve; how evolution produces novel structures, functions and behaviours; and how development, evolution and ecology are integrated to bring about and stabilize evolutionary change. The previous edition of this title, published in 1992, defined the terms and laid out the field for evolutionary developmental biology. This field is now one of the most active and fast growing within biology and this is reflected in this second edition, which is more than twice the length of the original and brought completely up to date. There are new chapters on major transitions in animal evolution, expanded coverage of comparative embryonic development and the inclusion of recent advances in genetics and molecular biology. The book is divided into eight parts which: place evolutionary developmental biology in the historical context of the search for relationships between development and evolution; detail the historical background leading to evolutionary embryology; explore embryos in development and embryos in evolution; discuss the relationship between embryos, evolution, environment and ecology; discuss the dilemma for homology of the fact that development evolves; deal with the importance of understanding how embryos measure time and place both through development and evolutionarily through heterochrony and heterotrophy; and set out the principles and processes that underlie evolutionary developmental biology. With over one hundred illustrations and photographs, extensive cross-referencing between chapters and boxes for ancillary material, this latest edition will be of immense interest to graduate and advanced undergraduate students in cell, developmental and molecular biology, and in zoology, evolution, ecology and entomology; in fact anyone with an interest in this new and increasingly important and interdisciplinary field which unifies biology.
Download or read book The Geological Record of Ecological Dynamics written by National Research Council and published by National Academies Press. This book was released on 2005-01-13 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to answer important questions about ecosystems and biodiversity, scientists can look to the past geological recordâ€"which includes fossils, sediment and ice cores, and tree rings. Because of recent advances in earth scientists' ability to analyze biological and environmental information from geological data, the National Science Foundation and the U.S. Geological Survey asked a National Research Council (NRC) committee to assess the scientific opportunities provided by the geologic record and recommend how scientists can take advantage of these opportunities for the nation's benefit. The committee identified three initiatives for future research to be developed over the next decade: (1) use the geological record as a "natural laboratory" to explore changes in living things under a range of past conditions, (2) use the record to better predict the response of biological systems to climate change, and (3) use geologic information to evaluate the effects of human and non-human factors on ecosystems. The committee also offered suggestions for improving the field through better training, improved databases, and additional funding.
Download or read book The Structure of Evolutionary Theory written by Stephen Jay Gould and published by Harvard University Press. This book was released on 2002-03-21 with total page 1099 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time--a landmark publication, both for its historical sweep and for its scientific vision. With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution. Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought. In 2001 the Library of Congress named Stephen Jay Gould one of America's eighty-three Living Legends--people who embody the "quintessentially American ideal of individual creativity, conviction, dedication, and exuberance." Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen--and may not see again--for well over a century.
