Antarctic Climate Evolution, Second Edition, enhances our
understanding of the history of the world's largest ice sheet, and
how it responded to and influenced climate change during the
Cenozoic. It includes terrestrial and marine geology,
sedimentology, glacier geophysics and ship-borne geophysics,
coupled with results from numerical ice sheet and climate modeling.
The book's content largely mirrors the structure of the Past
Antarctic Ice Sheets (PAIS) program (www.scar.org/science/pais),
formed to investigate past changes in Antarctica by supporting
multidisciplinary global research. This new edition reflects recent
advances and is updated with several new chapters, including those
covering marine and terrestrial life changes, ice shelves, advances
in numerical modeling, and increasing coverage of rates of change.
The approach of the PAIS program has led to substantial improvement
in our knowledge base of past Antarctic change and our
understanding of the factors that have guided its evolution.
This book focuses on British fossils and the story of life on our
islands, including details of the great fossil collections of
Britain.
Paleocological Research on Easter Island: Insights on Settlement,
Climate Changes, Deforestation and Cultural Shifts examines the
area's climatic and ecological history, a topic not usually
addressed in other literature. The book provides a thorough and
synthetic account of all paleoecological works developed to date,
including the latest discoveries. Finally, it attempts to match
paleoecological evidence with the results of other disciplines
creating a multidisciplinary framework. This approach to the field
is ideal for researchers, university professors and graduate
students in a varied range of disciplines and subdisciplines,
including ecology, paleoecology, paleoclimatology, biogeography,
sedimentology, and paleontology. Users will find synthesized
information on Easter Island from the last millennia that will help
pave the way towards an integrated interdisciplinary vision of the
island's environmental-ecological-cultural system as a complex
functional unit. Human and environmental deterministic views are
avoided and the Easter Island enigmas are analyzed under a holistic
perspective of continuous feedbacks and synergies among the
different components of the system.
Everyone is familiar with the dodo and the wooly mammoth, but
how many people have heard of the scimitar cat and the Falkland
Island fox? "Extinct Animals" portrays over 60 remarkable animals
that have been lost forever during the relatively recent geological
past. Each entry provides a concise discussion of the history of
the animal--how and where it lived, and how it became extinct--as
well as the scientific discovery and analysis of the creature. In
addition, this work examines what led to extinction--from the role
of cyclical swings in the Earth's climate to the spread of humans
and their activities. Many scientists believe that we are in the
middle of a mass extinction right now, caused by the human
undermining of the earth's complex systems that support life.
Understanding what caused the extinction of animals in the past may
help us understand and prevent the extinction of species in the
future.
"Extinct Animals" examines the biology and history of some of
the most interesting creatures that have ever lived, including: The
American Terror Bird, which probably became extinct over 1 million
years ago, who were massive predators, some of which were almost 10
feet tall; the Rocky Mountain Locust, last seen in 1902, formed the
most immense animal aggregations ever known, with swarms estimated
to include over 10 trillion insects; the Giant Ground Sloth, which
was as large as an elephant; and the Neandertals, the first
Europeans, which co-existed with prehistoric Homo sapiens. "Extinct
Animals" includes illustrations--many created for the work--that
help the reader visualize the extinct creature, and each entry
concludes with a list of resources for those who wish to do further
research.
This book envisages a multi-proxy approach using stable isotopes,
geochemical proxies, magnetic susceptibility and associated biotic
events for paleoclimatic and paleoenvironmental interpretations of
the Mesozoic sedimentary record of India. Mesozoic rocks of India
record abnormal sea level rise, greenhouse climate, intensified
volcanism, hypoxia in seawater, extensive black shale deposition,
and hydrocarbon occurrence. The Mesozoic has also witnessed mass
extinction events, evolution of dinosaurs, and breakdown of the
supercontinent Pangea and the formation of Gondwana. Although the
Mesozoic geology of India has witnessed significant progress in the
last century, literature survey reveals a huge gap in knowledge
regarding sequence stratigraphy, chemostratigraphy and key
geological events. A synthesis of sedimentological, paleontological
and chemical data is included to presenting a comprehensive
understanding of the Indian Mesozoic record to students,
researchers and professionals.
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.
