Book Description
The rapid evolution of terrestrial ecosystems in the Devonian Period combined with climate change and many global events had a pronounced influence on sedimentation and biodiversity in various terrestrial and marine settings. This volume presents a number of case studies which cover the following topics land-sea transitional settings, the role of ecological-evolutionary subunits, the diversity and palaeoecology of reef building organisms and microfloras with respect to sedimentary processes and global events.

Book Description
What do we now know about the origins of plants on land, from an evolutionary and an environmental perspective? The essays in this collection present a synthesis of our present state of knowledge, integrating current information in paleobotany with physical, chemical, and geological data.

Book Description
Stratigraphy has come to be indispensable to nearly all branches of the earth sciences, assisting such endeavors as charting the course of evolution, understanding ancient ecosystems, and furnishing data pivotal to finding strategic mineral resources. This book focuses on traditional and innovative stratigraphy techniques and how these can be used to reconstruct the geological history of sedimentary basins and in solving manifold geological problems and phenomena.

Book Description
This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.

Book Description
Presents information from the primary abiotic forces defining the system, and from the present hydrology, biogeochemistry and physics of major sites of organic carbon production of the McMurdo Dry Valleys. Additionally, research on the physical, chemical, and biological properties of the dry valley soils is included. The role of environmental management in long-term ecological studies is also addressed. The accompanying CDROM provides details and scale to visualize the McMurdo Dry Valleys from an ecosystem perspective.
