Book Description

The existence of rapid and even catastrophic turnovers within the Phanerozoic ecosystems has been discussed controversially for more than 170 years. Since 1980 this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth. This theory stimulated several thousand papers and is still controversial. The international research programme on "Global Biological Events in Earth History" attempts to bring the discussion back to the facts by using multidisciplinary investigations of the major Phanerozoic events. The results of an international group of experts are presented giving a wealth of information and a thorough discussion of the causes of the various global events.

Book Description

Their story began 500 million years ago, but we only started to get to know them in 1746, when Linné described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

Book Description

Ostracoda (Crustacea) are potentially excellent model organisms for evolutionary studies, because they combine an extensive fossil record with a wide recent distribution and therefore allow studies on both patterns and processes leading to extant diversity. The main scientific domains contributing theories, concepts, and data to evolutionary biology are morphology (including ontogeny), palaeontology, genetics, and ecology, and to all of these aspects ostracods can contribute. This is clearly illustrated by the fifteen papers presented under Theme 3 of the 13th International Symposium on Ostracoda (Chatham, UK) in 1997 which are grouped in the present proceedings, one of three volumes resulting from this meeting. The contributions deal with the evolution of both extant and fossil forms (including most of the Phanaerozoic), ecology of both marine and freshwater taxa, and (developmental) morphology of both soft parts and valves. Although the canvas is wide, each paper clearly shows how studies on Ostracoda can be relevant to general theory on evolutionary biology and ecology.

Book Description

Ostracod crustaceans, common microfossils in marine and freshwater sedimentary records, supply evidence of past climatic conditions via indicator species, transfer function and mutual climatic range approaches as well as the trace element and stable isotope geochemistry of their shells. As methods of using ostracods as Quaternary palaeoclimate proxies have developed, so too has a critical awareness of their complexities, potential and limitations. This book combines up-to-date reviews (covering previous work and summarising the state of the art) with presentations of new, cutting-edge science (data and interpretations as well as methodological developments) to form a major reference work that will constitute a durable bench-mark in the science of Ostracoda and Quaternary climate change. - In-depth and focused treatment of palaeoclimate applications - Provides durable benchmark and guide for all future work on ostracods - Presents new, cutting-edge science

Book Description

This book is the first volume of a new interdisciplinary series on "Impact Studies". The volumes of this series aim to include all aspects of research related to impact cratering - geology, geophysics, paleontology, geochemistry, mineralogy, petrology, planetolgy, etc. Future volumes will include monographs, field guides, conference proceedings, etc. All contributions in this book were peer-reviewed to ensure high scientific quality. The thirteen papers in the present volume result from a workshop of the European Science Foundation (ESF) IMPACT programme ("Response of the Earth System to Impact Processes"). This programme is an interdisciplinary effort aimed at understanding impact processes and their effects on the Earth System, including environmental, biological, and geological changes, and consequences for the biodiversity of ecosystems. The goals of the programme, and details about our activities, can be found on the web at . The IMPACT programme has currently 15 member nations from allover Europe. The activities of the programme range from workshops to specific topics regarding impact cratering, short courses on impact stratigraphy, shock metamorphism, etc. , mobility grants for students and young researchers, development of teaching aids, and publications. The third IMPACT workshop was held in Quillan, in the foothills of the French Pyrenees, in September 1999.

Book Description

The Late Devonian and Permian-Triassic intervals are among the most dynamic episodes of Earth history, marked by large secular changes in continental ecosystems, dramatic fluctuations in ocean oxygenation, major phases of biotic turnover, volcanism, bolide impact events, and rapid fluctuations in stable isotope systems and sea level. This volume highlights contributions from a broad range of geological sub-disciplines currently striving to understand these critical intervals of geologically rapid, global-scale changes.* Provides updated, current models for the mid-Late Devonian and Permian-Triassic mass extinction episodes* Highlights several new analytical approaches for developing quantitative datasets* Takes an integrated approach presenting datasets from a broad range of sub-disciplines

Book Description

The first book to review all the evidence concerning both the dinosaur extinctions and all the other major extinctions - of plant, animal, terrestrial, and marine life - in the history of life. All the extinction mechanisms are critically assessed, including meteorite impact, anoxia, and volcanism. - ;Why do mass extinctions occur? The demise of the dinosaurs has been discussed exhaustively, but has never been out into the context of other extinction events. This is the first systematic review of the mass extinctions of all organisms, plant and animal, terrestrial and marine, that have occurred in the history of life. This includes the major crisis 250 million years ago which nearly wiped out all life on Earth. By examining current paleontological, geological, and sedimentological evidence of environmental changes, the cases for explanations based on climate change, marine regressions, asteroid or comet impact, anoxia, and volcanic eruptions are all critically evaluated. -

Book Description

Seven original case-studies are presented in this volume, each describing the application of micropaleontology and palynology in applied geology: (1) a study of the modern distribution of coccolith sedimentation in the North Sea and its potential for future application in basin analysis; (2) ostracods are shown to be good paleoenvironmental indicators in the early Cretaceous and Tertiary; (3) a biogenic gas seep in the North Sea is shown to be marked by diagnostic benthonic foraminifera; (4) in the North Sea hydrocarbon exploration, integrated studies of micropaleontology have provided invaluable data; (5) palynofacies analysis are shown to be vital in determining depositional events and hydrocarbon source rock potential; (6) the application of paleontology and sedimentology to sequence stratigraphy is demonstrated in the early Cretaceous; and (7) the application of micropaleontology is shown to be an essential tool in both engineering and economic geology. Most chapters have been prepared by earth scientists from industry. The study of microfossils presented in this book provides invaluable data for stratigraphers, petroleum geologists and for engineers and economic geologists working in hydrocarbon exploration and basin analysis.

Book Description

There are many competitive works on the market concerning evolutionary biology, but this volume is quite distinctive in its idiographic aspect focusing on Ostracoda viewed from a wide range of disciplines, ages and environments. The book deals with various lines of idiographic biology and palaeontology of Ostracoda and nomothetic trials focusing strongly on evolutionary biology. Particular themes are morphology, biology, evolution, speciation, ecology, palaeoecology, deep sea fauna, biogeography, palaeobiogeography, biostratigraphy and exploration, all concerning Ostracoda.The last decade has witnessed a spectacular renewal of interest in the study of Otracoda, particularly in the evolutionary biology of Ostracoda, including speciation. Ostracoda are unique, ranging in age from the Cambrian period to modern times with carapaces ready to be preserved as fossils, providing various lines of invaluable evidence regarding evolutionary processes.More than 120 participants from 20 countries assembled at the Ninth International Symposium on Ostracoda and this book is a collection of all the papers presented at the Symposium, plus selected papers submitted by non-attending members. It presents an outstanding record of much pioneering research and will be of interest to specalists in Ostracoda as well as all earth and life scientists concerned with evolution. Its value is further enhanced by easy-to-use indexes of authors, localities and taxa.
