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 2021-05-07 with total page 565 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 one focuses on identifying parasitism in the fossil record, and sheds light on the distribution and ecological importance of parasite-host interactions over time. In order to better understand the evolutionary history of parasites and their relationship with changes in the environment, emphasis is given to viruses, bacteria, protists and multicellular eukaryotes as parasites. Particular attention is given to fungi and metazoans such as bivalves, cnidarians, crustaceans, gastropods, helminths, insects, mites and ticks as parasites. Researchers, specifically evolutionary (paleo)biologists and parasitologists, interested in the evolutionary history of parasite-host interactions as well as students studying parasitism will find this book appealing.
Download or read book Preparing Dinosaurs written by Caitlin Donahue Wylie and published by MIT Press. This book was released on 2021-08-31 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the work and workers in fossil preparation labs reveals the often unacknowledged creativity and problem-solving on which scientists rely. Those awe-inspiring dinosaur skeletons on display in museums do not spring fully assembled from the earth. Technicians known as preparators have painstakingly removed the fossils from rock, repaired broken bones, and reconstructed missing pieces to create them. These specimens are foundational evidence for paleontologists, and yet the work and workers in fossil preparation labs go largely unacknowledged in publications and specimen records. In this book, Caitlin Wylie investigates the skilled labor of fossil preparators and argues for a new model of science that includes all research work and workers. Drawing on ethnographic observations and interviews, Wylie shows that the everyday work of fossil preparation requires creativity, problem-solving, and craft. She finds that preparators privilege their own skills over technology and that scientists prefer to rely on these trusted technicians rather than new technologies. Wylie examines how fossil preparators decide what fossils, and therefore dinosaurs, look like; how labor relations between interdependent yet hierarchically unequal collaborators influence scientific practice; how some museums display preparators at work behind glass, as if they were another exhibit; and how these workers learn their skills without formal training or scientific credentials. The work of preparing specimens is a crucial component of scientific research, although it leaves few written traces. Wylie argues that the paleontology research community's social structure demonstrates how other sciences might incorporate non-scientists into research work, empowering and educating both scientists and nonscientists.
Download or read book Evolution of the Vertebrate Ear written by Jennifer A. Clack and published by Springer. This book was released on 2016-12-21 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.
Download or read book Freshwater Fishes written by Lionel Cavin and published by Elsevier. This book was released on 2017-05-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 15,000 species, nearly a quarter of the total number of vertebrate species on Earth, freshwater fishes are extremely varied. They include the largest fish species, the beluga at over 7 meters long, and the smallest, the Paedocypris at just 8 millimeters, as well as the carnivorous, such as the piranha, and the calm, such as the Chinese algae eater. Certain species evolve rapidly, cichlids for example, while others transform very slowly, like lungfish. The fossils of these animals are very diverse in nature, sometimes just small scattered bones where sites correspond to ancient river beds or magnificent fossils of entire fish where there was once a lake. This book covers the history of these fishes over the last 250 million years by exploring the links between their biological evolution and the paleogeographic and environmental transformations of our planet, whether these be gradual or sudden. - Gathers and synthetizes data from a vast number of publications regarding past freshwater assemblages and several fish lineages that invaded freshwaters - Describes the work of the author's own team, concerning fauna from the Cretaceous of France, Morocco, and Thailand - Presents the recent results of the tempo of diversification in freshwater environments and the evolutionary histories of clades and gar lineages

Available in PDF, EPUB and Kindle. Book excerpt: Comprising by far the largest and most diverse group of vertebrates, fishes occupy a broad swathe of habitats ranging from the deepest ocean abyss to the highest mountain lakes. Such incredible ecological diversity and the resultant variety in lifestyle, anatomy, physiology and behavior, make unraveling the evolutionary history of fishes a daunting task. The successor of a classic volume by the same title, Interrelationships of Fishes, provides the latest in the "state of the art" of systematics and classification for many of the major groups of fishes. In providing a sound phylogenetic framework from leading authorities in the field, this book is an indispensable reference for a broad range of biologists, especially students of fish behavior, anatomy, physiology, molecular biology, genetics and ecology--in fact, anyone who wishes to interpret their work on fishes in an evolutionary context. - Provides thorough and comprehensive treatment of the Phylogency of fishes - Assembles an International team of expert contributors - Useful to a wide variety of fish biologists
Download or read book Sturgeon biodiversity and conservation written by Vadim J. Birstein and published by Springer Science & Business Media. This book was released on 1997-05-31 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

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.
