Book Description
The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the palaeoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic palaeobotany and terrestrial palaeoecology.

Book Description
Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.

Book Description
No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.

Book Description
Published by the American Geophysical Union as part of theSpecial Publications Series. Tectonic, Climatic, and Cryospheric Evolution of the AntarcticPeninsula presents the analysis of data collected during theSHALDRIL program, which sampled the most complete Cenozoicstratigraphic section in the Antarctic Peninsula. The stratigraphicintervals sampled fill major gaps in the existing stratigraphicrecord in the region, which is believed to have been the last placein Antarctica to become fully glaciated and, as such, the lastrefugium for plants and animals living on the continent. Providingpreviously unpublished results from studies aimed at improving ourunderstanding of the changes in climate, glacial setting, and faunaand flora that took place over the past 30 million years, thevolume highlights include discussions of marine seismic and drillcore records documenting the initial growth and expansion of an icesheet across the northernmost Antarctic Peninsula continental shelfin the northwestern Weddell Sea. The book features: Detailed vegetation and phytoplankton evolution from greenhousethrough icehouse conditions in Antarctica's last refugium Sand grain texture and micromorphology indicating ice sheetcontrol of weathering style Exhumational history around the Drake Passage margins fromthermochronology and sediment provenance Comprehensive review of the opening of the ocean passagewaybetween Antarctica and South America and the associated regionaltectonics. Tectonic, Climatic, and Cryospheric Evolution of theAntarctic Peninsula will be of interest to geologists,climatologists, and glaciologists interested in climate andcryosphere evolution and those factors that regulate it.

Book Description
What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditionsâ€"or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient lifeâ€"and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening othersâ€"including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative toolsâ€"and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

Book Description
Antarctica preserves a rock record that spans three and a half billion years of history and has a remarkable story to tell about the evolution of our Earth, from the hottest crustal rocks yet found in an orogenic system, to the assembly and breakup of Gondwana in the Phanerozoic. This volume highlights our improved understanding of the tectonic events that have shaped Antarctica and how these potentially relate to supercontinent assembly and fragmentation. The internal constitution of the East Antarctic Shield is assessed using information available from the basement geology and from detritus preserved as Mesozoic sediments in the Trans Antarctic Mountains. Accretionary orogenesis along the proto-Pacific margin of Antarctica is examined and the volumes of intracrustal melting compared with juvenile magma additions in these complex orogenic systems assessed. This special volume demonstrates the diversity of approaches required to elucidate and understand crustal evolution and evaluate the supercontinent concept.
