Living organisms exhibit specific responses when confronted with
sudden changes in their environmental conditions. The ability of
the cells to acclimate to their new environment is the integral
driving force for adaptive modification of the cells. Such
adaptation involves a number of cellular and biochemical alteration
including metabolic homeostasis and reprogramming of gene
expression. Changes in metabolic pathways are generally short-lived
and reversible, while the consequences of gene expression are a
long-term process and may lead to permanent alternation in the
pattern of adaptive responses.
The heart possesses remarkable ability to adapt itself against any
stressful situation by increasing resistance to the adverse
consequences. Stress composes the foundation of many degenerative
heart diseases including atherosclerosis, spasm, thrombosis,
cardiomyopathy, and congestive heart failure. Based on the concept
that excessive stress may play a crucial role in the pathogenesis
of ischemic heart disease, attempts were made to design methods for
preventing of myocardial injury. Creation of stress reactions by
repeated ischemia and reperfusion or subjecting the hearts to heat
or oxidative stress enables them to meet the future stress
challenge. Repeated stress exposures adapt the heart to withstand
more severe stress reactions probably by upregulating the cellular
defense and direct accumulation of intracellular mediators, which
presumably constitute the material basis of increased adaptation to
stress. Thus, the powerful cardioprotective effect of adaptation is
likely to originate at the cellular and molecular levels that
compose fundamental processes in the prophylaxis of such diseases.
Volume six of the Advances in Organ Biology series contains
state-of-the-art reviews on myocardial preservation and cellular
adaptation from the leading authorities in this subject.

This book encompasses the body of available scientific information
on the notothenioid fish Pleuragramma antarctica commonly known as
Antarctic silverfish. This plankton-feeder of the intermediate
trophic level is the most abundant fish in the coastal regions of
high Antarctica, and plays a pivotal ecological role as the main
prey of top predators like seals, penguins, whales and Antarctic
toothfish. Broad circum-polar distribution, a key role in the
Antarctic shelf pelagic ecosystem, and adaptations makes
understanding the species' likely response to environmental change
relevant to foresee the potential responses at the local ecosystem
level. Additionally, a detailed understanding of the abundance and
trophic interactions of such a dominant keystone species is a vital
element of informing the development of marine spatial planning and
marine protected areas in the Antarctic continental shelf region.
Experts in the field provide here unique insights into the
evolutionary adaptation, eco-physiology, trophic ecology,
reproductive and population ecology of the Antarctic silverfish and
provide new clues about its vulnerability in facing the challenges
of the ongoing environmental changes.
This book covers advanced concepts and creative ideas with regard
to insect biorational control and insecticide resistance
management. Some chapters present and summarize general strategies
or tactics for managing insect pests such as the principles of IPM
in various crop systems and biorational control of insect pests,
advances in organic farming, alternative strategies for controlling
orchard and field-crop pests. Other chapters cover alternative
methods for controlling pests such as disruption of insect
reproductive systems and utilization of semiochemicals and
diatomaceous earth formulations, and developing bioacoustic methods
for mating disruption. Another part is devoted to insecticide
resistance: mechanisms and novel approaches for managing insect
resistance in agriculture and in public health.
This book examines the long-term fate of invasive species by
detailing examples of invaders from different zoological and
botanical taxa from various places around the world. Readers will
discover what happened, after a century or so, to 'classical'
invaders like rabbits in Australia, house sparrows in North
America, minks in Europe and water hyacinths in Africa and Asia.
Chapters presented in the book focus on eighteen species in the
form of in-depth case studies including: earthworms, zebra mussels,
Canadian water weed, Himalayan balsam, house sparrows, rabbits,
crayfish plague, Colorado beetles, water hyacinths, starlings,
Argentine ant, Dutch elm disease, American mink, cane toad,
raccoons, Canadian beavers, African killer bees and warty comb
jelly. Invaded areas described are in Africa, Asia, Australia,
Europe, North America, Pacific islands, and South America. Readers
will get some ideas about the likely future of current invaders
from the fate of old ones. This book is intended for undergraduates
studying environmental sciences, researchers and members of
environmental NGO's.
This volume focuses on the latest methods used to sequence,
assemble, and analyze insect genomes. The collection of protocols
in this book provides an introduction to the workflows and
bioinformatics tools available for researchers. The chapters cover
a range of useful topics such as determining genome size by flow
cytometry; High Molecular Weight DNA extraction; improvements to a
genome assembly provided by long-range sequencing approaches;
assessments of orthology and single-copy genes at different
phylogenetic levels; detecting regulatory regions with FAIRE,
RAMPAGE, and computational analysis of cis-regulatory modules in
insects; bioinformatics analysis of epigenetic modifications,
high-throughput scanning of insect genomes (TEEseq) for the
presence of endosymbionts, and leveraging genome sequence
information to design RNAi strategies. Written in the highly
successful Methods in Molecular Biology series format, chapters
include introductions to their respective topics, lists of the
necessary materials and reagents, step-by-step, readily
reproducible laboratory protocols, and tips on troubleshooting and
avoiding known pitfalls. Cutting-edge and thorough, Insect
Genomics: Methods and Protocols is a valuable resource for graduate
students, postdocs, and novice research scientists who are
interested in learning more about this developing field.
The content of this book is intended to provide the toxicologist in
drug development in the pharmaceutical and biotechnology industries
with a broad understanding of bone and its interactions with other
organ systems in safety assessments. The book is divided into three
parts. The first part describes our current understanding of bone
biology and its primary regulatory pathways. Additional chapters
address regulatory and study design considerations for
incorporating bone end points in toxicology studies, with special
consideration being given to juvenile toxicology studies. This is
intended to address recent regulatory requirements to evaluate
skeletal development for drugs in development for pediatric
populations. The second part of the book describes the principal
techniques and methods used in bone research; understanding how
these end-points are derived is fundamental to their appropriate
application. These first two parts of the book provide the
background and the means to develop the concepts in part three
which describes bone and its interaction with other organ systems.
The unique series of chapters in part three, contributed to by key
leaders in their respective fields and in bone research, provides a
comprehensive collective work. Although constantly evolving, the
crosstalk and interaction of the skeleton with several organ
systems is now recognized and well documented, such as for the
reproductive system, muscle and kidney, while our understanding of
the interaction with other organ systems, such as the immune system
and CNS, is in its infancy. Recent work highlights the key role of
the skeleton in the regulation of energy metabolism and the impact
this has on research in metabolic diseases such as obesity and
diabetes. The hope is that this book will enlighten many and
encourage more to explore the impact of new compounds on the
skeleton in the development of effective and safe drugs.
Nature's Machines: An Introduction to Organismal Biomechanics
presents the fundamental principles of biomechanics in a concise,
accessible way while maintaining necessary rigor. It covers the
central principles of whole-organism biomechanics as they apply
across the animal and plant kingdoms, featuring brief,
tightly-focused coverage that does for biologists what H. M.
Frost's 1967 Introduction to Biomechanics did for physicians.
Frequently encountered, basic concepts such as stress and strain,
Young's modulus, force coefficients, viscosity, and Reynolds number
are introduced in early chapters in a self-contained format, making
them quickly available for learning and as a refresher. More
sophisticated, integrative concepts such as viscoelasticity or
properties of hydrostats are covered in the later chapters, where
they draw on information from multiple earlier sections of the
book. Animal and plant biomechanics is now a common research area
widely acknowledged by organismal biologists to have broad
relevance. Most of the day-to-day activities of an animal involve
mechanical processes, and to the extent that organisms are shaped
by adaptive evolution, many of those adaptations are constrained
and channelized by mechanical properties. The similarity in body
shape of a porpoise and a tuna is no coincidence. Many may feel
that they have an intuitive understanding of many of the mechanical
processes that affect animals and plants, but careful biomechanical
analyses often yield counterintuitive results: soft, squishy kelp
may be better at withstanding pounding waves during storms than
hard-shelled mollusks; really small swimmers might benefit from
being spherical rather than streamlined; our bones can operate
without breaking for decades, whereas steel surgical implants
exhibit fatigue failures in a few months if not fully supported by
bone.
Cheetahs: Biology and Conservation reports on the science and
conservation of the cheetah. This volume demonstrates the
interdisciplinary nature of research and conservation efforts to
study and protect the cheetah. The book begins with chapters on the
evolution, genetics, physiology, ecology and behavior of the
species, as well as distribution reports from range countries.
These introductory chapters lead into discussions of the challenges
facing cheetah survival, including habitat loss, declining prey
base, human-wildlife conflict, illegal trade, and newly-emerging
threats, notably climate change. This book also focuses on
conservation strategies and solutions, including environmental
education and alternative livelihoods. Chapters on the role of
captive cheetahs to conservation and the long-term research of the
species are included, as are a brief discussion of the methods and
analyses used to study the cheetah. The book concludes with the
conservation status and future outlook of the species. Cheetahs:
Biology and Conservation is a valuable resource for the regional
and global communities of cheetah conservationists, researchers,
and academics. Although cheetah focussed the book provides
information relevant to the study of broader topics such as
wildlife conservation, captive breeding, habitat management,
conservation biology and animal behaviour. Cover photograph by

The Flowering of Australia's Rainforests provides a comprehensive
introduction to the pollination ecology, evolution and conservation
of Australian rainforest plants, with particular emphasis on
subtropical rainforests and their associated pollinators. This
significantly expanded second edition includes new information on
the impact of climate change, fire, fragmentation and invasive
species. Rainforests continue to be a focus of global conservation
concern, not only from threats to biodiversity in general, but to
pollinators specifically. Within Australia, this has been
emphasised by recent cataclysmic fire impacts, ongoing extreme
drought events, and the wider consideration of climate change. This
second edition strengthens coverage of these issues beyond that of
the first edition. The Flowering of Australia's Rainforests makes
timely contributions to our understanding of the nature and
function of the world's pollinator fauna, plant-reproduction
dependencies, and the evolutionary pathway that has brought them to
their current state and function. Illustrated with 150 colour
plates of major species and rainforest formations, this reference
work will be of value to ecologists and field naturalists,
botanists, conservation biologists, ecosystemmanagers and community
groups involved in habitat restoration. FEATURES: Provides an
overview of the pollination ecology of Australia's rainforests in a
world rainforest context. In particular discusses the pollination
ecology of threatened subtropical rainforests, including the impact
of climate change, fragmentation, fire and invasive species.
Provides an introductory review of plant evolution and
plant-pollinator relationships. Discusses pollination syndromes and
the role and function of pollinator groups. Serves as a companion
volume to The Invertebrate World of Australia's Subtropical
Rainforests
Erythropoietin, Volume 105, the latest release in the Vitamins and
Hormones series first published in 1943, and the longest-running
serial published by Academic Press, provides up-to-date information
on crystal structures and basic structural studies on neurotrophins
and their receptors, neurotrophin functions and the biological
actions of neurotrophins related to clinical conditions and
disease. Topics covered in this new volume include Erythropoietin
Receptor Structural Domains, Analysis of the Asymmetry of Activated
EPO Receptor Enables Designing Small Molecule Agonists, Endogenous
Erythropoietin, Erythropoietin Receptor Signaling and Lipid Rafts,
and Erythropoietin and Hypothalamic-Pituitary Axis. Each thoroughly
reviewed volume focuses on a single molecule or disease that is
related to vitamins or hormones, with the topic broadly interpreted
to include related substances, such as transmitters, cytokines,
growth factors and others. This volume documents the activities of
this vital molecule, also describing the structure and function of
erythropoietin and its receptor.
Bioassays: Advanced Methods and Applications provides a thorough
understanding of the applications of bioassays in monitoring
toxicity in aquatic ecosystems. It reviews the newest tests and
applications in discovering compounds and toxins in the
environment, covering all suitable organisms, from bacteria, to
microorganisms, to higher plants, including invertebrates and
vertebrates. By learning about newer tests, water pollution control
testing can be less time and labor consuming, and less expensive.
This book will be helpful for anyone working in aquatic
environments or those who need an introduction to ecotoxicology or
bioassays, from investigators, to technicians and students.
Documenting and understanding intricate ecological interactions
involving insects is a central need in conservation, and the
specialised and specific nature of many such associations is
displayed in this book. Their importance is exemplified in a broad
global overview of a major category of interactions, mutualisms, in
which the interdependence of species is essential for their mutual
wellbeing. The subtleties that sustain many mutualistic
relationships are still poorly understood by ecologists and
conservation managers alike. Examples from many parts of the world
and ecological regimes demonstrate the variety of mutualisms
between insect taxa, and between insects and plants, in particular,
and their significance in planning and undertaking insect
conservation - of both individual species and the wider contexts on
which they depend. Several taxonomic groups, notably ants, lycaenid
butterflies and sucking bugs, help to demonstrate the evolution and
flexibility of mutualistic interactions, whilst fundamental
processes such as pollination emphasise the central roles of,
often, highly specific partnerships. This compilation brings
together a wide range of relevant cases and contexts, with
implications for practical insect conservation and increasing
awareness of the roles of co-adaptations of behaviour and ecology
as adjuncts to designing optimal conservation plans. The three
major themes deal with the meanings and mechanisms of mutualisms,
the classic mutualisms that involve insect partners, and the
environmental and conservation lessons that flow from these and
have potential to facilitate and improve insect conservation
practice. The broader ecological perspective advances the
transition from primary focus on single species toward consequently
enhancing wider ecological contexts in which insect diversity can
thrive.
Insect Pests of Millets: Systematics, Bionomics, and Management
focuses on protecting the cultivated cereals that many worldwide
populations depend on for food across the semi-arid tropics of the
world. Providing coverage of all the major cultivated millets,
including sorghum, pearlmillet, finger millet, barnyard millet,
prosomillet, little millet, kodomillet, and foxtail millet, this
comprehensive book on insect pests is the first of its kind that
explores systematics, bionomics, distribution, damage, host range,
biology, monitoring techniques, and management options, all
accompanied by useful illustrations and color plates. By exploring
the novel aspects of Insect-plant relationships, including host
signaling orientation, host specialization, pest - host
evolutionary relationship, and biogeography of insects and host
plants, the book presents the latest ecologically sound and
innovative techniques in insect pest management from a general
overview of pest management to new biotechnological interventions.
The success of duck hunters throughout much of North America each
fall depends to a large degree upon the spring productivity of the
breeding waterfowl in the northern prairie states and the central
provinces of Canada. In southern Manitoba, in the Waterfowl
Research Station, a privately endowed outdoor laboratory owned by
the North American Wildlife Foundation and operated by the Wildlife
Management Institute. Its principal purpose is to determine facts
useful in the management and perpetuation of this international
migratory resource. When Dr. Lyle K. Sowls began his studies at
Delta in 1946, many wide gaps remained in the knowledge of the
relationship of breeding ducks to their home range. There were many
scattered observations and a growing mass of data accumulated
through the study of banding returned; but the activities of
individual ducks during the critical spring months and the
activities and the fate of broods each summer remained largely a
mystery. Sowls, working toward his doctorate in wildlife management
as a graduate student of the University of Wisconsin, studied the
waterfowl at Delta for five years in an attempt to plug some of
those gaps through intensive study of the waterfowl on one limited
are. His studies developed new techniques and brought out new facts
that were startling even to waterfowl biologists, facts of prime
importance to the duck hunter or to any one interest in the future
of America's waterfowl flights. As a result of Dr. Sowls' research,
new light has been shed on such factors as predation, renesting,
and homing habits of the important species of game ducks, and
already have become the basis for revised hunting regulations and
give a new understanding of waterfowl problems.
