Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The object of this book is to explain how to create a synthesis of complex biostratigraphic data, and how to extract from such a synthesis a relative time scale based exclusively on the fossil content of sedimentary rocks. Such a time scale can be used to attribute relative ages to isolated fossil-bearing samples. The book is composed of 10 chapters together with several appendices. It is a totally revised version of 'Biochronological Correlations' published in 1991 and includes various new chapters. The book offers a solution for the theoretical problem of how fossils can be used to make reliable quantitative stratigraphic correlations in sedimentary geology. It also describes the use of highly efficient software along with several examples. The authors compare their theoretical model with 2 other relevant studies: probabilistic stratigraphy and constrained optimization (CONOP).

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book is the first of its kind, providing in-depth analysis of the retrograde evolution occurring during major extinction periods. The text offers a non-strictly adaptative explanation of repetition of phyla after the major extinctions, utilizing a study of seven phylogenetically distinct groups. This opens a new experimental field in evolutionary biology with the possibility of reconstructing ancestral forms in lab by applying artificial stresses.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The object of this book is to explain how to create a synthesis of complex biostratigraphic data, and how to extract from such a syn thesis a relative time scale based exclusively on the fossil content of sedimentary rocks. Such a time scale can be used to attribute relative ages to isolated fossil-bearing samples. From a practical point of view, the method described in this book will particularly interest paleontologists and geologists who must construct zonations and establish correlations on the basis of bio stratigraphic data that are both plentiful and apparently contra dictory. It is well known that the difficulties involved in constructing bio chronologic scales are largely due to the discontinuous nature of the fossil record. We know that the relationships between the first ap pearances (or disappearances) of different fossil species are rarely constant in stratigraphic sections that are distant from each other. It if often extremely difficult to discover datums or sets of species that are useful in making significant biochronologic correlations on a large scale. The theoretical model explained here (known as the Unitary As sociation Method) provides clear solutions to most of these problems. That method is purely deterministic, as opposed to statistical and probabilistic analytical techniques producing 'average' ranges. We demonstrate in Chapter 15 why most of these techniques produce results which are usually not compatible with the original biostrati graphic observations (i.e., the taxonomic contents of the studied sam ples are not reproduced in the outputs).; The application of a deterministic mathematical model in solving stratigraphical problems leads to more realistic results than by statistic or probabilistic approaches. The aim of this analytical method, elaborated by the author, is to resolve systematically the multiple contradictions inherent to the stratigrahic record of fossil species. A theoretical part treating the interpretation of highly complex biostratigraphic data is followed by the presentation of the computer-aided Unitary Association Method. Geologists and structural geologists as well as micro-palaentologists in science and practice will benefit from this new tool in stratigraphy. Das Problem der biostratigraphischen Korrelation stellt sich Geologen, Paläontologen, Strukturgeologen, Sedimentologen in Lehre und Forschung, aber auch in der Erdölindustrie. Für sie bietet dieses Buch die Grundlage für einen sedimentstratigraphischen Kurs und eine hervorragende Methode zur Erstellung einer biostratigraphischen Zeitskala.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution.Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of 'reverse evolution' by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.
