This book focuses on the interactive effects of environmental
stresses with plant and ecosystem functions, especially with
respect to changes in the abundance of carbon dioxide. The
interaction of stresses with elevated carbon dioxide are presented
from the cellular through whole plant ecosystem level. The book
carefully considers not only the responses of the above-ground
portion of the plant, but also emphasizes the critical role of
below-ground (rhizosphere) components (e.g., roots, microbes, soil)
in determining the nature and magnitude of these interactions.
* Will rising CO2 alter the importance of environmental stress in
natural and agricultural ecosystems?
* Will environmental stress on plants reduce their capacity to
remove CO2 from the atmosphere?
* Are some stresses more important than others as we concern
ourselves with global change?
* Can we develop predictive models useful for scientists and
policy-makers?
* Where should future research efforts be focused?
The emerging multidisciplinary field of earth system science sets
out to improve our understanding functioning ecosystems, at a
global level across the entire planet. Stable Isotopes and
Biosphere - Atmosphere Interactions looks to one of its most
powerful tools - the application of stable isotope analyses - to
understanding biosphere-atmosphere exchange of the greenhouse
gases, and synthesizes much of the recent progress in this work.
Stable Isotopes and Biosphere - Atmosphere Interactions describes
recent progress in understanding the mechanisms, processes and
applications of new techniques. It makes a significant contribution
to the emerging, multidisciplinary study of the Earth as an
interacting system. This book will be an important reference for
students and researchers in biology, ecology, biogeochemistry,
meteorology, and atmospheric science and will be invaluable for
anyone with any interest in the future of the planet.
* Describes applications of new stable isotope techniques to the
emerging fields of earth system science and global change
* Illustrates advances in scaling of physiological processes from
leaf/soil to the global scale
* Contains state-of-the-art, critical reviews written by
international researchers and experts
The Rhetoric of Religious Cults takes as its departure point the
notion that 'cults' have a distinctive language and way of
recruiting members. First outlining a rhetorical framework, which
encompasses contemporary discourse analysis, the persuasive texts
of three movements - Scientology, Jehovah's Witnesses and Children
of God - are analysed in detail and their discourse compared with
other kinds of recruitment literature. Cults' distinctive negative
profile in society is not matched by a linguistic typology. Indeed,
this negative profile seems to rest on the semantics and
application of the term 'cult' itself.
Increased longevity and better health are changing the nature of
family life. In the context of changes in the world of work,
increased divorce and a declining welfare state, multi-generation
or 'beanpole families' are a potential resource for family support.
Focusing on four-generation families and the two central careers of
the life course - employment and care - Working and Caring Over the
Twentieth Century explores this question. Based upon new research
that employed biographical methods, it maps in detail from 1910 to
the late 1990s the lives of men and women as great-grandparents,
grandparents and parents. The book provides unique insights into
processes of change and continuity in family lives and the ways in
which different generations of men and women make sense of their
lives.
Ecology at the ecosystem level has both necessitated and benefited from new methods and technologies as well as those adapted from other disciplines. With the ascendancy of ecosystem science and management, the need has arisen for a comprehensive treatment of techniques used in this rapidly-growing field. Methods in Ecosystem Science answers that need by synthesizing the advantages, disadvantages and tradeoffs associated with the most commonly used techniques in both aquatic and terrestrial research.The book is divided into sections addressing carbon and energy dynamics, nutrient and water dynamics, manipulative ecosystem experiements and tools to synthesize our understanding of ecosystems. Detailed information about various methods will help researchers choose the most appropriate methods for their particular studies. Prominent scientists discuss how tools from a variety of disciplines can be used in ecosystem science at different scales.
This book examines the differences and similarities in the earth
system components - the ocean, atmosphere, and the land - between
western portions of the northern and southern Western Hemispheres,
past, present, and projected. The book carefully examines the
physical and biological patterns and responses of given biomes, or
ecological communities in the two regions. Special emphasis is
placed on the relationship of physicial and biotic systems to
biogeochemistry and the evolving biota patterns of land margins and
surfaces. The text concludes with an assessment of the direct
impact on humans on these biomes, giving full consideration to the
land-use drivers of global change.

The climbing habit in plants has apparently evolved numerous times.
Species that climb are well represented in habitats ranging from
tropical rain forests through temperate forests to semi-deserts.
The Biology of Vines, first published in 1992, is a treatment of
what is known about climbing plants, written by a group of experts
and covering topics ranging from the biomechanics of twining to
silvicultural methods for controlling vine infestations. Also
included are detailed accounts of climbing plant evolution, stem
anatomy and function, climbing mechanics, carbon and water
relations, reproductive ecology, the role of vines in forest
communities and their economic importance. The chapters are based
on research on herbaceous vines and woody climbers (lianas) in both
temperate and tropical zones, deserts and rain-forests and Old and
New World areas. Much remains to be learned about the biology of
these plants, but this volume provides a substantial foundation
upon which further research can be based.
No other disjunct pieces of land present such striking similarities
as the widely sepa 1 rated regions with a mediterranean type of
climate, that is, the territories fringing the Mediterranean Sea,
California, Central Chile and the southernmost strips of South
Mrica and Australia. Similarities are not confined to climatic
trends, but are also reflected in the physiognomy ofthe vegetation,
in land use patterns and frequently in the general appearance of
the landscape. The very close similarities in agricultural
practices and sometimes also in rural settlements are dependent on
the climatic and edaphic analogies, as well as on a certain
commonality in qdtural history. This is certainly true for the
Mediterranean Sea basin which in many ways represents a sort of
ecological-cultural unit; this is also valid for CaUfornia and
Chile, which were both settled by Spaniards and which showed
periods of vigorous commercial and cultural interchanges as during
the California gold rush. One other general feature is the massive
interchange of cultivated and weed species of plants that has
occurred between the five areas of the world that have a
mediterranean-type climate, with the Mediterranean basin region
itself as a major source. In spite of their limited territorial
extension, probably no other parts of the world have played a more
fundamental role in the history of mankind. Phoenician, Etruscan,
Hellenic, Jewish, Roman, Christian andArab civilizations, among
others, haveshapedmanyofman's present attitudes, including his
position and perception vis-a-vis nature."
Harold A. Mooney and Richard J. Hobbs At present there is enormous
concern about the changes that are occurring on the surface of the
earth and in the earth's atmosphere, primarily as a result of human
activities. These changes, particularly in the atmosphere, have the
potential for altering the earth's habitability. International pro
grams unprecedented in scope, including the International Geosphere
Biosphere Program, have been initiated to describe and understand
these changes. The global change program will call for coordinated
measure ments on a global scale of those interactive physical and
biological pro cesses that regulate the earth system. The program
will rely heavily on the emerging technology of remote sensing from
airborne vehicles, particularly satellites. Satellites offer the
potential of continuously viewing large seg ments of the earth's
surface, thus documenting the changes that are occur ring. The
task, however, is not only to document global change, which will be
an enormous job, but also to understand the significance of these
changes to the biosphere. Effects on the biosphere may cover all
spatial scales from global to local. The possibility of measuring
biosphere function remot ly and continuously from satellite imagery
must be explored quickly and thoroughly in order to meet the
challenge of understanding the con sequences of global change.
Initial guidelines and approaches are currently being formulated
(Dyer and Crossley, 1986; JOI, 1984; NAS, 1986; Rasool, 1987).
There are many conceptual and technical issues that must be
resolved H. A. Mooney and R. J."

The biota of the earth is being altered at an unprecedented rate.
We are witnessing wholesale exchanges of organisms among geographic
areas that were once totally biologically isolated. We are seeing
massive changes in landscape use that are creating even more
abundant succes sional patches, reductions in population sizes, and
in the worst cases, losses of species. There are many reasons for
concern about these trends. One is that we unfortunately do not
know in detail the conse quences of these massive alterations in
terms of how the biosphere as a whole operates or even, for that
matter, the functioning of localized ecosystems. We do know that
the biosphere interacts strongly with the atmospheric composition,
contributing to potential climate change. We also know that changes
in vegetative cover greatly influence the hydrology and
biochemistry ofa site or region. Our knowledge is weak in important
details, however. How are the many services that ecosystems provide
to humanity altered by modifications of ecosystem composition?
Stated in another way, what is the role of individual species in
ecosystem function? We are observing the selective as well as
wholesale alteration in the composition of ecosystems. Do these
alterations matter in respect to how ecosystems operate and provide
services? This book represents the initial probing of this central
ques tion. It will be followed by other volumes in this series
examining in depth the functional role of biodiversity in various
ecosystems of the world."
The diversity of the earth's climates superimposed upon a complex
configuration of physical features has provided the conditions for
the evolution of a remarkable array of living things which are
linked together into complex ecosystems. The kinds of organisms
comprising the ecosystems of the world, and the nature of their
interactions, have constantly changed through time due to
coevolutionary interactions along with the effects of a continually
changing physical environ ment. In recent evolutionary time there
has been a dramatic and ever-accelerating rate of change in the
configuration of these ecosystems because of the increasing
influence of human beings. These changes range from subtle
modifications caused by anthropogenically induced alterations in
atmospheric properties to the total destruction of ecosystems. Many
of these modifications have provided the fuel, food, and fiber
which have allowed the expansion of human populations.
Unfortunately, there have been many unanticipated changes which
accompanied these modifications which have had effects detrimental
to human welfare in cluding substantial changes in water and air
quality. For example, the use of high-sulfur coal to produce energy
in parts of North America is altering the properties of freshwater
lakes and forests because of acidification."
Prolonged seasonal drought affects most of the tropics, including
vast areas presently or recently dominated by 'dry forests'. These
forests have received scant attention, despite the fact that humans
have used and changed them more than rain forests. This volume
reviews the available information, often making contrasts with
wetter forests. The world's dry forest heterogeneity of structure
and function is shown regionally. In the neotropics, biogeographic
patterns differ from those of wet forests, as does the spectrum of
plant life-forms in terms of structure, physiology, phenology and
reproduction. Biomass distribution, nutrient cycling, below-ground
dynamics and nitrogen gas emission are also reviewed. Exploitation
schemes are surveyed, and examples are given of non-timber product
economies. It is hoped that this review will stimulate research
leading to more conservative and productive management of dry
forests.

State-of-the-art approaches and insightful discussions on
challenging topics in skull base surgery Advances in endoscopic,
microsurgical, radiosurgical, and pharmacotherapeutic strategies
have revolutionized the treatment of skull base pathologies.
Controversies in Skull Base Surgery, edited by Andrew Little and
Michael Mooney and authored by esteemed multidisciplinary
contributors, focuses on management strategies and treatment
options for a wide range of tumors affecting the skull base, while
addressing the most urgent and challenging questions facing skull
base surgeons today. Throughout nine sections and 46 chapters,
experts describe the treatment of neoplasms such as vestibular
schwannoma, meningioma, pituitary adenoma, craniopharyngioma,
chordoma, cranial nerve schwannoma, sinonasal malignancies, and
others. In many chapters, authors provide instructional case
studies and suggestions for future studies to help clarify areas of
controversy. This textbook is unique in that it tackles problems
typically minimized or ignored by other texts that impact a
patient's quality of life and recovery. Key Highlights
Reader-friendly tables feature concise summaries, author pearls,
and levels of available evidence Pearls and insights on hotly
debated issues such as the role of radiosurgery, surgery vs.
medical management, radical resection vs. subtotal resection, and
proton-beam vs. photon therapy for various pathologic conditions
Controversies not frequently discussed in depth, including the use
of lumbar drains, postoperative antibiotics, and cerebral
revascularization in skull base surgery; multidisciplinary
collaboration in endoscopic endonasal surgery; skull base
reconstruction techniques; and the future of robotics in skull base
surgery This stellar resource will benefit all residents and
advanced practice providers who evaluate and treat patients with
skull base pathologies, including neurosurgeons, otolaryngologists,
and radiation and medical oncologists. This book includes

Building on their important findings in The Source of the River,
the authors now probe even more deeply into minority
underachievement at the college level. Taming the River examines
the academic and social dynamics of different ethnic groups during
the first two years of college. Focusing on racial differences in
academic performance, the book identifies the causes of students'
divergent grades and levels of personal satisfaction with their
institutions. Using survey data collected from twenty-eight
selective colleges and universities, Taming the River considers all
facets of student life, including who students date, what fields
they major in, which sports they play, and how they perceive their
own social and economic backgrounds. The book explores how black
and Latino students experience pressures stemming from campus
racial climate and "stereotype threat"--when students underperform
because of anxieties tied to existing negative stereotypes.
Describing the relationship between grade performance and
stereotype threat, the book shows how this link is reinforced by
institutional practices of affirmative action. The authors also
indicate that when certain variables are controlled, minority
students earn the same grades, express the same college
satisfaction, and remain in school at the same rates as white
students. A powerful look at how educational policies unfold in
America's universities, Taming the River sheds light on the social
and racial factors influencing student success.
Invasive alien species are among today's most daunting
environmental threats, costing billions of dollars in economic
damages and wreaking havoc on ecosystems around the world. In 1997,
a consortium of scientific organizations including SCOPE, IUCN, and
CABI developed the Global Invasive Species Programme (GISP) with
the explicit objective of providing new tools for understanding and
coping with invasive alien species.
Invasive Alien Species is the final report of GISP's first phase
of operation, 1997-2000, in which authorities from more than thirty
countries worked to examine invasions as a worldwide environmental
hazard. The book brings together the world's leading scientists and
researchers involved with invasive alien species to offer a
comprehensive summary and synthesis of the current state of
knowledge on the subject.
Invasive alien species represent a critical threat to natural
ecosystems and native biodiversity, as well as to human economic
vitality and health. The knowledge gained to date in understanding
and combating invasive alien species can form a useful basis on
which to build strategies for controlling or minimizing the effects
in the future. Invasive Alien Species is an essential reference for
the international community of investigators concerned with
biological invasions.
The rapidly changing nature of animal production systems,
especially increasing intensification and globalization, is playing
out in complex ways around the world. Over the last century,
livestock keeping evolved from a means of harnessing marginal
resources to produce items for local consumption to a key component
of global food chains. "Livestock in a Changing Landscape" offers a
comprehensive examination of these important and far-reaching
trends. The books are an outgrowth of a collaborative effort
involving international nongovernmental organizations including the
United Nations Food and Agriculture Organization (UN FAO), the
International Livestock Research Institute (ILRI), the Swiss
College of Agriculture (SHL), the French Agricultural Research
Centre for International Development (CIRAD), and the Scientific
Committee for Problems of the Environment (SCOPE). "Volume 1"
examines the forces shaping change in livestock production and
management; the resulting impacts on landscapes, land use, and
social systems; and potential policy and management responses.
"Volume 2" explores needs and draws experience from region-specific
contexts and detailed case studies. The case studies describe how
drivers and consequences of change play out in specific
geographical areas, and how public and private responses are shaped
and implemented. Together, the volumes present new, sustainable
approaches to the challenges created by fundamental shifts in
livestock management and production, and represent an essential
resource for policy makers, industry managers, and academics
involved with this issue
