Invertebrates are conspicuous, influential components in all of the
ecosystems of the world. Assemblages of invertebrates assume an
organizing function and hence may be considered as "webmasters" in
these ecosystems. This book reviews and assesses our current
understanding of invertebrates in terrestrial and
terrestrially-dominated (lower-order stream) ecosystems. It
emphasizes the centrality of the activity of invertebrates, which
influence ecosystems function far out of proportion to their
physical mass in a wide range of situations, particularly at the
soil interface between land and air (litter/soil), water and land
(sediments) and in tree canopies and root/soil systems.
Agrarian Landscapes in Transition researches human interaction with
the earth. With hundreds of acres of agricultural land going out of
production every day, the introduction, spread, and abandonment of
agriculture represents the most pervasive alteration of the Earth's
environment for several thousand years. What happens when humans
impose their spatial and temporal signatures on ecological regimes,
and how does this manipulation affect the earth and nature's desire
for equilibrium?
Studies were conducted at six Long Term Ecological Research sites
within the US, including New England, the Appalachian Mountains,
Colorado, Michigan, Kansas, and Arizona. While each site has its
own unique agricultural history, patterns emerge that help make
sense of how our actions have affected the earth, and how the earth
pushes back. The book addresses how human activities influence the
spatial and temporal structures of agrarian landscapes, and how
this varies over time and across biogeographic regions. It also
looks at the ecological and environmental consequences of the
resulting structural changes, the human responses to these changes,
and how these responses drive further changes in agrarian
landscapes.
The time frames studied include the ecology of the earth before
human interaction, pre-European human interaction during the rise
and fall of agricultural land use, and finally the biological and
cultural response to the abandonment of farming, due to complete
abandonment or a land-use change such as urbanization.
Despite the billions of dollars we've poured into foreign wars,
homeland security, and disaster response, we are fundamentally no
better prepared for the next terrorist attack or unprecedented
flood than we were in 2001. Our response to catastrophe remains
unchanged: add another step to airport security, another meter to
the levee wall. This approach has proved totally ineffective:
reacting to past threats and trying to predict future risks will
only waste resources in our increasingly unpredictable world. In
Learning from the Octopus , ecologist and security expert Rafe
Sagarin rethinks the seemingly intractable problem of security by
drawing inspiration from a surprising source: nature. Biological
organisms have been living- and thriving- on a risk-filled planet
for billions of years. Remarkably, they have done it without
planning, predicting, or trying to perfect their responses to
complex threats. Rather, they simply adapt to solve the challenges
they continually face. Military leaders, public health officials,
and business professionals would all like to be more adaptable, but
few have figured out how. Sagarinargues that we can learn from
observing how nature is organized, how organisms learn, how they
create partnerships, and how life continually diversifies on this
unpredictable planet. As soon as we dip our toes into a cold
Pacific tidepool and watch what we thought was a rock turn into an
octopus, jetting away in a cloud of ink, we can begin to see the
how human adaptability can mimic natural adaptation. The same
mechanisms that enabled the octopus's escape also allow our immune
system to ward off new infectious diseases, helped soldiers in Iraq
to recognize the threat of IEDs, and aided Google in developing
faster ways to detect flu outbreaks. While we will never be able to
predict the next earthquake, terrorist attack, or market
fluctuation, nature can guide us in developing security systems
that are not purely reactive but proactive, holistic, and
adaptable. From the tidepools of Monterey to the mountains of
Kazakhstan, Sagarin takes us on an eye-opening tour of the security
challenges we face, and shows us how we might learn to respond more
effectively to the unknown threats lurking in our future.
Richard D. Alexander is an accomplished entomologist who turned his
attention to solving some of the most perplexing problems
associated with the evolution of human social systems. Using
impeccable Darwinian logic and elaborating, extending and adding to
the classic theoretical contributions of pioneers of behavioral and
evolutionary ecology like George Williams, William Hamilton and
Robert Trivers, Alexander developed the most detailed and
comprehensive vision of human social evolution of his era. His
ideas and hypotheses have inspired countless biologists,
anthropologists, psychologists and other social scientists to
explore the evolution of human social behavior in ever greater
detail, and many of his seminal ideas have stood the test of time
and come to be pillars of our understanding of human social
evolution. This volume presents classic papers or chapters by Dr.
Alexander, each focused on an important theme from his work.
Introductions by Dr. Alexander's former students and colleagues
highlight the importance of his work to the field, describe more
recent work on the topic, and discuss current issues of contention
and interest.

Award in Environment/Ecology People across the world know that to
tell how old a tree is, you count its rings. Few people, however,
know that research into tree rings has also made amazing
contributions to our understanding of Earth's climate history and
its influences on human civilization over the past 2,000 years. In
her captivating book Tree Story, Valerie Trouet reveals how the
seemingly simple and relatively familiar concept of counting tree
rings has inspired far-reaching scientific breakthroughs that
illuminate the complex interactions between nature and people.
Trouet, a leading tree-ring scientist, takes us out into the field,
from remote African villages to radioactive Russian forests,
offering readers an insider's look at tree-ring research, a
discipline known as dendrochronology. Tracing her own professional
journey while exploring dendrochronology's history and
applications, Trouet describes the basics of how tell-tale tree
cores are collected and dated with ring-by-ring precision,
explaining the unexpected and momentous insights we've gained from
the resulting samples. Blending popular science, travelogue, and
cultural history, Tree Story highlights exciting findings of
tree-ring research, including the fate of lost pirate treasure,
successful strategies for surviving California wildfire, the secret
to Genghis Khan's victories, the connection between Egyptian
pharaohs and volcanoes, and even the role of olives in the fall of
Rome. These fascinating tales are deftly woven together to show us
how dendrochronology sheds light on global climate dynamics and
uncovers the clear links between humans and our leafy neighbors.
Trouet delights us with her dedication to the tangible appeal of
studying trees, a discipline that has taken her to austere and
beautiful landscapes around the globe and has enabled scientists to
solve long-pondered mysteries of Earth and its human inhabitants.
When organisms are deliberately or accidentally introduced into a
new ecosystem a biological invasion may take place. These so-called
'invasive species' may establish, spread and ecologically alter the
invaded community. Biological invasions by animals, plants,
pathogens or vectors are one of the greatest environmental and
economic threats and, along with habitat destruction, a leading
cause of global biodiversity loss. In this book, more than 50
worldwide invasion scientists cover our current understanding of
biological invasions, its impacts, patterns and mechanisms in both
aquatic and terrestrial systems.
The book discusses the complex interactions between plants and
their associated microbial communities. It also elucidates the ways
in which these microbiomes are connected with the plant system, and
how they affect plant health. The different chapters describe how
microbiomes affect plants with regard to immunity, disease
conditions, stress management and productivity. In addition, the
book describes how an 'additional plant genome' functions as a
whole organ system of the host, and how it presents both challenges
and opportunities for the plant system. Moreover, the book includes
a dedicated section on using omics tools to understand these
interactions, and on exploiting them to their full potential.
The rhizosphere in soil environments refers to the narrow zone of
soil influenced by the root and exudates. Microbial populations in
the rhizosphere can be 10 - 100 times larger than the populations
in the bulk soil. Therefore, the rhizosphere is bathed in root
exudates and microbial metabolites and the chemistry and biology at
the soil-root interface is governed by biotic (plant roots,
microbes) and abiotic (physical and chemical) interactions.
The research on biotic and abiotic interactions in the rhizosphere
should, thus, be an issue of intense interest for years to come.

This edited volume in the Theoretical Ecology series addresses the
historical development and evolution of theoretical ideas in the
field of ecology. Not only does it recount the history of the
discipline by practitioners of the science of ecology, it includes
commentary on these historical reflections by philosophers of
science. Even though the theories discussed are, in many cases, are
at the forefront of research, the language and approach make this
material accessible to non-theoreticians. The book is structured in
5 major sections including population ecology, epidemiology,
community ecology, evolutionary biology and ecosystem ecology. In
each section a chapter by an eminent, experienced ecologist is
complemented by analysis from a newer, cutting-edge researcher.
* Reflection on the past and future of ecology
* A historical overview of major ideas in the field of
ecology
* Pairing of historical views by ecologists along with a
philosophical commentary directed at the practicing scientists
views by a philosopher of science.
* Historical analysis by practicing ecologists including anectodal
experiences that are rarely recorded.
* Based on a very popular symposium at the 2002 Ecological Society
of America annual meeting in Tucson, AZ.
The Phytochemical Society of North America held its forty-fourth
annual meeting in Ottawa, Ontario, Canada from July 24-28, 2004.
This year's meeting was hosted by the University of Ottawa and the
Canadian Forest Service, Great Lakes Forestry Centre and was held
jointly with the International Society of Chemical Ecology. All of
the chapters in this volume are based on papers presented in the
symposium entitled "Chemical Ecology and Phytochemistry of Forest
Ecosystems." The Symposium Committee, Mamdouh Abou-Zaid, John T.
Arnason, Vincenzo deLuca, Constance Nozzolillo, and Bernard
Philogene, assembled an international group of phytochemists and
chemical ecologists working primarily in northern forest
ecosystems. It was a unique interdisciplinary forum of scientists
working on the cutting edge in their respective fields. While most
of these scientists defy the traditional labels we are accustomed
to, they brought to the symposium expertise in phytochemistry,
insect biochemistry, molecular biology, genomics and proteomics,
botany, entomology, microbiology, mathematics, and ecological
modeling.
* A collection of papers presented at the 44th Annual meeting of
the Phytochemical Society of North America
* Representation from a unique interdisciplinary forum of
scientists
* Includes discussions on new genomics research in forest health
This volume continues the retrospective analyses of Volumes I and
II, but goes beyond that in an attempt to understand how phenolic
acids are partitioned in seedling-solution and
seedling-microbe-soil-sand culture systems and how phenolic acid
effects on seedlings may be related to the actual and/or
conditional physicochemical properties (e.g., solubility,
hydrophobicity, pKa, molecular structure and soil
sorption/desorption) of simple phenolic acids. Specifically, it
explores the quantitative partitioning (i.e., source-sink
relationships) of benzoic and cinnamic acids in cucumber
seedling-solution and cucumber seedling-microbe-soil-sand systems
and how that partitioning may influence phenolic acid effects on
cucumber seedlings. Regressions, correlations and conceptual and
hypothetical models are used to achieve these objectives. Cucumber
seedlings are used as a surrogate for phenolic acid sensitive
herbaceous dicotyledonous weed seedlings. This volume was written
specifically for researchers and their students interested in
understanding how a range of simple phenolic acids and potentially
other putative allelopathic compounds released from living plants
and their litter and residues may modify soil chemistry, soil and
rhizosphere microbial biology, seedling physiology and seedling
growth. In addition, this volume describes the potential
relationships, where they may exist, for direct transfer of organic
compounds between plants, plant communication and plant-plant
allelopathic interactions and addresses the following questions:
Can physicochemical properties of phenolic acids be used as tools
to help understand the complex behavior of phenolic acids and the
ultimate effects of phenolic acids on sensitive seedlings? What
insights do laboratory bioassays and the conceptual and
hypothetical models of laboratory systems provide us concerning the
potential behavior and effects of phenolic acids in field systems?
What potential role may phenolic acids play in broadleaf-weed
seedling emergence in wheat debris cover crop no-till systems?
