Book Synopsis Echinoderm Paleobiology by : William I. Ausich
Download or read book Echinoderm Paleobiology written by William I. Ausich and published by Indiana University Press. This book was released on 2008-07-18 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.
Book Synopsis A Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology by : Colin D. Sumrall
Download or read book A Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology written by Colin D. Sumrall and published by Cambridge University Press. This book was released on 2023-04-13 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, dividing it into axial regions generally associated with elements of the ambulacral system and extraxial regions that are not. UEH describes the detailed construction of the axial skeleton, dividing it into homologous plates and plate series based on symmetry, early growth, and function. These hypotheses are not in conflict; the latter is rooted in refinement of the former. Some interpretive differences arise because many of the morphologies described from eleutherozoan development are difficult to reconcile with Paleozoic forms. Conversely, many elements described for Paleozoic taxa by UEH, such as the peristomial border plates, are absent in eleutherozoans. This Element recommends these two hypotheses be used together to generate a better understanding of homology across Echinodermata.
Book Synopsis Molecular Paleobiology of the Echinoderm Skeleton by : Jeffrey R. Thompson
Download or read book Molecular Paleobiology of the Echinoderm Skeleton written by Jeffrey R. Thompson and published by Cambridge University Press. This book was released on 2022-12-01 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. The genetic regulatory networks underpinning development in echinoderms are some of the best known for any model group. Additionally, the echinoderms have an excellent fossil record, elucidating in in detail the evolutionary changes underpinning morphological evolution. In this Element, the echinoderms are discussed as a model group for molecular palaeobiological studies, integrating what is known of their development, genomes, and fossil record. Together, these insights shed light on the molecular and morphological evolution underpinning the vast biodiversity of echinoderms, and the animal kingdom more generally.
Book Synopsis Computational Fluid Dynamics and its Applications in Echinoderm Palaeobiology by : Imran A. Rahman
Download or read book Computational Fluid Dynamics and its Applications in Echinoderm Palaeobiology written by Imran A. Rahman and published by Cambridge University Press. This book was released on 2020-11-19 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational fluid dynamics (CFD), which involves using computers to simulate fluid flow, is emerging as a powerful approach for elucidating the palaeobiology of ancient organisms. Here, Imran A. Rahman describes its applications for studying fossil echinoderms. When properly configured, CFD simulations can be used to test functional hypotheses in extinct species, informing on aspects such as feeding and stability. They also show great promise for addressing ecological questions related to the interaction between organisms and their environment. CFD has the potential to become an important tool in echinoderm palaeobiology over the coming years.
Book Synopsis Echinoderm Morphological Disparity: Methods, Patterns, and Possibilities by : Bradley Deline
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.
Book Synopsis Virtual Paleontology by : Jennifer E. Bauer
Download or read book Virtual Paleontology written by Jennifer E. Bauer and published by Cambridge University Press. This book was released on 2021-11-11 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Imaging and visualizing fossils in three dimensions with tomography is a powerful approach in paleontology. Here, the authors introduce select destructive and non-destructive tomographic techniques that are routinely applied to fossils and review how this work has improved our understanding of the anatomy, function, taphonomy, and phylogeny of fossil echinoderms. Building on this, this Element discusses how new imaging and computational methods have great promise for addressing long-standing paleobiological questions. Future efforts to improve the accessibility of the data underlying this work will be key for realizing the potential of this virtual world of paleontology.
Book Synopsis Disarticulation and Preservation of Fossil Echinoderms: Recognition of Ecological-Time Information in the Echinoderm Fossil Record by : William I. Ausich
Download or read book Disarticulation and Preservation of Fossil Echinoderms: Recognition of Ecological-Time Information in the Echinoderm Fossil Record written by William I. Ausich 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 history of life on earth is largely reconstructed from time-averaged accumulations of fossils. A glimpse at ecologic-time attributes and processes is relatively rare. However, the time-sensitive and predictability of echinoderm disarticulation makes them model organisms to determine post-mortem transportation and allows recognition of ecological-time data within paleocommunity accumulations. Unlike many other fossil groups, this has allowed research on many aspects of echinoderms and their paleocommunities, such as the distribution of soft tissues, assessment of the amount of fossil transportation prior to burial, determination of intraspecific variation, paleocommunity composition, estimation of relative abundance of taxa in paleocommunities, determination of attributes of niche differentiation, etc. Crinoids and echinoids have received the most amount of taphonomic research, and the patterns present in these two groups can be used to develop a more thorough understanding of all echinoderm clades.

Book Synopsis Testing Character Evolution Models in Phylogenetic Paleobiology by : April Wright
Download or read book Testing Character Evolution Models in Phylogenetic Paleobiology written by April Wright and published by Cambridge University Press. This book was released on 2021-08-26 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a tree, and then inference of a macroevolutionary model using that tree. Newer models blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve many more parameters than prior models, including parameters about which empiricists may have little intuition. In this Element, we set forth a framework for fitting complex, hierarchical models. The authors ultimately fit and use a joint tree and diversification model to estimate a dated phylogeny of the Cincta (Echinodermata), a morphologically distinct group of Cambrian echinoderms that lack the fivefold radial symmetry characteristic of extant members of the phylum. Although the phylogeny of cinctans remains poorly supported in places, this Element shows how models of character change and diversification contribute to understanding patterns of phylogenetic relatedness and testing macroevolutionary hypotheses.

Book Synopsis Functional Micromorphology of the Echinoderm Skeleton by : Przemyslaw Gorzelak
Download or read book Functional Micromorphology of the Echinoderm Skeleton written by Przemyslaw Gorzelak and published by Cambridge University Press. This book was released on 2021-02-11 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Echinoderms elaborate a calcite skeleton composed of numerous plates with a distinct microstructure (stereom) that can be modelled into different shapes thanks to the use of a transient amorphous calcium carbonate (ACC) precursor phase and the incorporation of an intraorganic matrix during biomineralization. A variety of different types of stereom microarchitecture have been distinguished, each of them optimized for a specific function. For instance, a regular, galleried stereom typically houses collagenous ligaments, whereas an irregular, fine labyrinthic stereom commonly bears muscles. Epithelial tissues, in turn, are usually associated with coarse and dense stereom microfabrics. Stereom can be preserved in fossil echinoderms and a wide array of investigating methods are available. As many case studies have shown, a great deal of important paleobiological and paleoecological information can be decoded by studying the stereom microstructure of extinct echinoderms.

Book Synopsis The Taphonomy of Echinoids by : James H. Nebelsick
Download or read book The Taphonomy of Echinoids written by James H. Nebelsick and published by Cambridge University Press. This book was released on 2021-10-21 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of echinoid evolution, diversity, and ecology has always suffered from the fact that they are represented by taxa showing widely differing architectural designs of their multi-plated skeletons, inhabiting a large range of marine paleoenvironments, which result in highly varying taphonomic biases dictating their presence and recognition. This Element addresses the taphonomy of echinoids and includes: a general introduction to the morphological features of echinoids that play a role in their preservation; a review of processes which play an important role in the differential preservation of both regular and irregular echinoids including predation and transport; a summary of taphonomic pathways included in actualistic studies for recent sea urchins and then reconstructed for fossil taxa; and finally, a case study of the variation of echinoid taphonomy across a shelf gradient using the rich Miocene echinoid fauna of Sardinia.
Book Synopsis Life Sculpted by : Anthony J. Martin
Download or read book Life Sculpted written by Anthony J. Martin and published by University of Chicago Press. This book was released on 2023-06-02 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As the co-discoverer of the first known burrowing dinosaur and a popular science author, Anthony J. Martin is an expert at explaining his fossil-finding work to broad audiences. In this engaging book, Martin uses modern and fossil traces to introduce readers to a menagerie of animals and other lifeforms that dig, crunch, bore, and otherwise reshape our planet. We meet elephants that dig ballroom-sized caves alongside volcanoes, parrotfishes that chew coral reefs and poop out sandy beaches, dinosaur-eating crocodiles, and moon snails that drill into clams, or even other moon snails. In a detective story that spans millions of years, ranging from microbes to whales, Martin shows how when life got hard, life got boring, using bodies and behavior to hide, eat, attack, and defend, affecting both our world and our understanding of evolution, climate, and life itself"--
Book Synopsis Reproductive and Developmental Strategies by : Kazuya Kobayashi
Download or read book Reproductive and Developmental Strategies written by Kazuya Kobayashi and published by Springer. This book was released on 2018-06-01 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides new insights into the universality of biological systems in animal reproduction and development by a comparative study of a variety of mechanisms in animals ranging from basal invertebrates to vertebrates, including mammals. Animals accomplish genetic diversity through meiosis and fertilization, and during embryogenesis animals must produce specialized cell types, including germ cells, in accordance with their individual body plan. This series of phenomena is essential to the continuity of life in the animal kingdom, and animals show various reproductive and developmental strategies. This volume, comprising four parts, reviews animal kingdom diversity, including reproductive strategies and germ cell differentiation mechanisms (Part 1), sex determination and differentiation (Part2), the mechanisms of fertilization (Part 3), and body axis formation (Part 4). Readers will find descriptions of the reproduction or development of 180 species, 13 phyla, 35 classes, 74 orders, 117 families, and 151 genera in this book. Of particular interest is the diversity of molecules and mechanisms used to achieve the same biological purpose in different animals. Undergraduates, graduate students, and professional scientists who want a deeper understanding of animal reproductive and developmental mechanisms will find this book to be of great value.
