Book Description
Renowned researchers summarize the current knowledge on ammonoid paleobiology. The book begins with a description of the systematic position of the Ammonoidea within the Cephalopoda, providing the phylogenetic framework for the rest of the book. Following discussions include soft- and hard-part morphology of ammonoids, rate of growth and ontogeny, and taphonomy and ecology. Closing chapters explore the distribution of ammonoids in time and space as well as their extinction at the end of the Cretaceous. With its diverse viewpoints and new material, this resource will benefit researchers and graduate students in paleontology, marine biology, and evolutionary biology.

Book Description
This comprehensive and systematic text book provides teachers and students alike with a profound, yet concise reference for the analysis of narrative texts. It provides appropriate and differentiated terminological and methodological tools to all the questions that arise when analyzing a narrative text. An advantage of this textbook is that the narrative theory models and concepts are presented in understandable and operational analytical categories and parameters and illustrated by tables and matrices to help make the sophisticated analysis easier to understand and memorize. Exemplary model analyses are provided to present and test the performance of this method.This book is valuable not only to literary scholars but is also suitable to teachers and students.Lehrende und Studierende, die einen Erzähltext analysieren wollen, finden in diesem umfassenden, systematischen, profunden und zugleich übersichtlichen Lehrbuch und Nachschlagewerk ein geeignetes und differenziertes terminologisches und methodisches Instrumentarium, um alle Fragen, die bei der Analyse eines Erzähltextes auftauchen, beantworten zu können. Ein Vorzug des vorliegenden Handbuches besteht darin, dass die erzähltheoretischen Modelle und Konzepte in verständliche und operative analytische Kategorien und Parameter umgesetzt und durch Tabellen, Matrizen und graphische Darstellung veranschaulicht werden, um die anspruchsvollen analytischen Raster besser fass- und memorierbar zu machen. In exemplarischen Musteranalysen wird die Leistungsfähigkeit der vorliegenden Erzähltextanalyse erprobt. Das Buch wendet sich nicht nur an Literaturwissenschaftler, sondern ist auch für Lehrkräfte und Schüler geeignet

Book Description
This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

Book Description
More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.

Book Description
Theoretical morphology--which seeks to sketch the range of forms that biological entities could take, with the ultimate goal of discovering why certain forms exist but others do not--is among paleontology's most significant contributions to the understanding of evolution. Today, with the aid of computers in developing conceivable morphologies, the discipline has been able to advance into a remarkable tool for the study of evolution. Yet despite these advances, the field remains largely untapped and ripe with research potential. In this volume, paleontologist George McGhee presents the first complete overview of the field, its advancements in recent years, and the challenges ahead. Theoretical Morphology provides readers with the background they need to launch their own research. McGhee describes the steps involved in defining the geometric parameters (theoretical morphospaces) for an organic form in order to generate a spectrum of other possible forms that have never actually appeared. He also addresses the simulation of actual processes of morphogenesis, with the goal of attaining a more nuanced comprehension of how evolutionary processes work. Theoretical Morphology takes readers through a variety of theoretical morphospaces including those for univalved, bivalved, discrete, and branching growth systems. With a glossary of terms and a comprehensive list of references on the subject, this is an excellent handbook for graduate students or professional scientists interested in employing these cutting-edge techniques in their own research.
