Biological homogenization is the dominant process shaping the
future global biosphere. As global transportation becomes faster
and more frequent, it is inevitable that biotic intermixing will
increase. Unique local biotas will become extinct only to be
replaced by already widespread biotas that can tolerate human
activities. This process is affecting all aspects of our world:
language, economies, and ecosystems alike. The ultimate outcome is
the loss of uniqueness and the growth of uniformity. In this way,
fast food restaurants exist in Moscow and Java Sparrows breed on
Hawaii. Biological homogenization qualifies as a global
environmental catastrophe. The Earth has never witnessed such a
broad and complete reorganization of species distributions.
Coastal ecosystems are centres of high biological productivity, but
their conservation is often threatened by numerous and complex
environmental factors. Citing examples from the major littoral
habitats worldwide, such as sandy beaches, salt marshes and
mangrove swamps, this text characterises the biodiversity of
coastline environments and highlights important aspects of their
maintenance and preservation, aided by the analysis of key
representative species. Leaders in the field provide reviews of the
foremost threats to coastal networks, including the effects of
climate change, invasive species and major pollution incidents such
as oil spills. Further discussion underscores the intricacies of
measuring and managing coastline species in the field, taking into
account the difficulties in quantifying biodiversity loss due to
indirect cascading effects and trophic skew. Synthesising the
current state of species richness with present and projected
environmental pressures, the book ultimately establishes a research
agenda for implementing and improving conservation practices moving
forward.
Biological invaders represent one of the primary threats to the
maintenance of global biodiversity, human health, and the success
of human economic enterprises. The continuing globalization of our
society ensures that the need to understand the process of
biological invasion will only increase in the future. There is also
a growing recognition that the study of biological invaders
provides a unique insight into basic questions in ecology and
evolution.
The study of exotic birds has had a particularly long history and
has come to represent a fascinating intersection between the study
of biological invasions, avian conservation biology, and basic
principles of ecology and evolution. Avian Invasions summarizes and
synthesizes this unique historical record and unravels the insights
that the study of exotic birds brings to all three of these
research strands. It includes chapters on the well-known
contributions of exotic bird study to ecological science, and on
the post-establishment evolution of introduced bird populations.
The result is the most comprehensive picture yet of the invasion
process.
Avian Invasions is aimed at professional avian biologists and
ornithologists as well as graduate students of avian ecology,
evolution and conservation. It also appeals to a more general
audience of invasion ecologists.

Beginning at the turn of the century, Rudolf Steiner began to
express a passionate interest in Christianity. For him, the event
he called the "Mystery of Golgotha" is more than the central event
of Christianity; it is, in fact, the turning point in time for all
human and earthly evolution. In his Autobiography, Steiner
clarified his views on Christianity: "Some of what I said and wrote
during that period 1890s] seems to contradict the way I described
Christianity later on. This is because, when I wrote the word
Christianity, I was referring to the teachings of a "world beyond"
that was active in all Christian doctrines at the time. The whole
meaning of religious experiences pointed to a world of spirit, one
that was supposed to be unattainable by human intellect. Whatever
religion might have to say and whatever precepts for moral life it
might offer arise from what is revealed to human beings from
outside. My own direct, inner perception of spirit objected to
this; it wanted to experience the worlds of both spirit and the
physical in perceptions of the human being and nature. And my
ethical individualism objected to this. It rejected the external
support of commandments for morality; such support came instead as
the result of spiritual soul development within the human being,
where divinity lives. That was a trying time for my soul as I
looked at Christianity. This period lasted from the time I left the
Weimar work until I wrote my book Christianity as Mystical Fact.
These kinds of tests are obstacles, placed in one's path by destiny
(or karma), and they must be overcome through spiritual
development. In these talks, Rudolf Steiner offers his profound
insights into the essential truths behind the Christ event, as well
as the historic and prehistoric events-on Earth and in the
spiritual worlds-leading up to the turning point in time. He shows
that the ancient mysteries of the East, the Persians, the
Egyptians, the Greeks, and the streams behind those impulses-going
back to Atlantis and Lemuria-all lead to the event of Christ's
incarnation and the Mystery of Golgotha, through which the Earth
became the body of Christ. Further, Steiner talks about what those
events mean for the future of humanity and the Earth." The Gospel
of St. John and Its Relation to the Other Gospels is an essential
document in the literature of Christology and for understanding the
central place of esoteric Christianity in Anthroposophy.
Published by Sinauer Associates, an imprint of Oxford University
Press. The abiotic characteristics of the environment-including
temperature, oxygen availability, salinity, and hydrostatic
pressure-present challenges to all biochemical structures and
processes. This volume first examines the nature of these
perturbations to biochemical systems and then elucidates the major
adaptive strategies that enable organisms from all Domains of
Life-Archaea, Bacteria, and Eukarya-to conserve common types of
biochemical structures and processes across a wide range of
environments. In addition to these conservative adaptations that
foster a biochemical unity among diverse species, other adaptations
can be viewed as innovative changes that enable organisms to
exploit new features of the environment that may themselves be the
result of biological activities. The opening chapter outlines the
basic principles of biochemical adaptations and raises the
questions that serve as the focal points for the detailed analysis
found in the next three chapters, which are devoted to the study of
relationships involving oxygen, temperature, and water-solute
effects. In these three chapters, the effects of the variable in
question on fundamental biochemical processes and structures are
examined. This analysis forms a basis for the subsequent analysis
of how adaptive changes modify biochemical systems to establish
environmental optima and tolerance limits. This analysis includes
examples from all Domains of Life to emphasize the commonality of
the fundamental strategies of biochemical adaptation. The final
chapter examines the challenges organisms face from the rapid
environmental changes that are occurring in the Anthropocene. The
effects of co-occurring changes in multiple stressors are examined
to provide a realistic and integrative analysis of effects of
global change. The underlying genetic capacities of different types
of organisms to adapt to rapid environmental change are discussed
to provide a basis for predicting the relative success different
species-including our own-face in a rapidly changing world.
In this dynamic look at the current state of character education,
Alan Lockwood assesses its strengths and weaknesses and finds fault
with leading advocates for failing to respond to sound critiques of
their work. Lockwood argues that contemporary character education
can be significantly improved by using key principles from
established theories and research on developmental psychology. He
offers numerous examples to support his recommendations while
inviting character education theorists and practitioners to
generate their own implications from his presentation. This book is
a valuable resource for anyone interested in improving the quality
of values-based education for children and adolescents.
Rudolf Steiner shows the need to "expand the horizon of life into
the breadth of the world" in order to overcome today's hermitlike
existence. He shows that the path to becoming true citizens of the
cosmos is through the forces of the Archangel Michael, who is
always present and prepared to help us.
