The book presents comprehensive information on fundamental, and
applied knowledge for developing varieties resistant individually
as well as to all the major pathogens of crucifers, such as Albugo,
Alternaria, Erysiphe, Hyaloperonospora, Plasmodiophora,
Leptosphaeria, Sclerotinia, Turnip mosaic virus, Verticillium, and
Xanthomonas through the use of latest biotechnological approaches
including identification of R genes and their incorporation into
agronomically superior varieties. The chapters include the
information's viz., principles of host resistance, identification
of R-genes sources, inheritance of disease resistance, host
resistance signaling network system to multiple stresses. The book
also covers transfer of disease resistance, and management of
disease resistance. Standardized, reproducible techniques are also
included for the researchers of cruciferous crops for developing
resistant cultivars. The book deals with the gaps in understanding,
knowledge of genomics, and offers suggestions for future research
priorities in order to initiate the advance research on disease
resistance. This book is immensely useful to the researchers
especially Brassica breeders, teachers, extension specialists,
students, industrialists, farmers, and all others who are
interested to grow healthy, and profitable cruciferous crops all
over the world.
Information is a core concept in animal communication: individuals
routinely produce, acquire, process and store information, which
provides the basis for their social life. This book focuses on how
animal acoustic signals code information and how this coding can be
shaped by various environmental and social constraints. Taking
birds and mammals, including humans, as models, the authors explore
such topics as communication strategies for "public" and "private"
signaling, static and dynamic signaling, the diversity of coded
information and the way information is decoded by the receiver. The
book appeals to a wide audience, ranging from bioacousticians,
ethologists and ecologists to evolutionary biologists. Intended for
students and researchers alike, it promotes the idea that Shannon
and Weaver's Mathematical Theory of Communication still represents
a strong framework for understanding all aspects of the
communication process, including its dynamic dimensions.
Plastics have now been our most used materials for over fifty
years. This book adopts a new approach, exploring plastics'
contribution from two perspectives: as a medium for making and
their value in societal use. The first approach examines the
multivalent nature of plastics materiality and their impact on
creativity through the work of artists, designers and
manufacturers. The second perspective explores attitudes to
plastics and the different value systems applied to them through
current research undertaken by design, materials and socio-cultural
historians. The book addresses the environmental impact of plastics
and elucidates the ways in which they can and must be part of the
solution. The individual viewpoints are provocative and
controversial but together they present a balanced and scholarly
un-picking of the debate that surrounds this ubiquitous group of
materials. The book is essential reading for a wide academic
readership interested in the Arts and Humanities, especially Design
and Design History; Anthropology; and Cultural, Material and Social
Histories.
This book discusses recent brain research and the potentially
dangerous dual-use applications of the findings of these research
projects. The book is divided into three sections: Part I examines
the rise in dual-use concerns within various state's chemical and
biological non-proliferation regime's during this century, as well
as the rapid technologically driven advances in neuroscience and
the associated possible misuse considerations in the same period.
Part II reviews the brain research projects in the EU, USA, Japan,
China and several other countries with regard to their objectives,
achievements and measures to deal with the problem of dual-use.
Part III assesses the extent to which the results of this civil
neuroscience work, which is intended to be benign, are being, and
could be protected against future hostile applications in the
development of novel chemical and biological weapons.
This is the past as we've never seen it before. Otherlands is an epic, exhilarating journey into deep time, showing us the Earth as it used to exist, and the worlds that were here before ours.
Award-winning young palaeobiologist Thomas Halliday immerses us in a series of ancient landscapes, from the mammoth steppe in Ice Age Alaska to the lush rainforests of Eocene Antarctica, with its colonies of giant penguins, to Ediacaran Australia, where the moon is far brighter than ours today. We visit the birthplace of humanity; we hear the crashing of the highest waterfall the Earth has ever known; and we watch as life emerges again after the asteroid hits, and the age of the mammal dawns.
Otherlands is a staggering imaginative feat: an emotional narrative that underscores the tenacity of life - yet also the fragility of seemingly permanent ecosystems, including our own. To read it is to see the last 500 million years not as an endless expanse of unfathomable time, but as a series of worlds, simultaneously fabulous and familiar.
This book examines the biology of tuco-tucos (Ctenomys) from an
evolutionary perspective. Historically, these subterranean rodents
have long attracted the attention of scientists due to its
remarkable chromosomes variability and rapid diversification. A
wealth of knowledge on physiology, ecology, genetics, morphology,
paleontology, and taxonomy has been documented in the last 70 years
through numerous single publications. In this volume, expert
investigators review and frame these essays with the breadth of
current understanding. The collection of chapters are presented
into the major topics: i) Evolution of Ctenomys, ii) Geographic
Patterns, iii) Organismal Biology, and iv) Environmental
Relationships. Given its scope, the book will be of interest to
both students and researchers and may stimulate further research
with this exciting model on a wide range of evolutionary topics.

This book provides concrete scientific basis that we can conceive
the possibility of modifying or even completely canceling aging
process, despite the fact that aging is commonly regarded as the
result of the overall effects of many uncontrollable degenerative
phenomena. The authors illustrate in detail the mechanisms by which
cells and the whole organism age. Actions by which it is possible,
or will be possible within a limited time, to operate for modifying
aging are also debated. The discussion is conducted within the
frame and the concepts of evolutionary medicine, which is also
indispensable for distinguishing between the manifestations of
aging and: (i) diseases that worsen with age, and (ii) acceleration
of normal aging rates, caused by unhealthy lifestyle habits and
other avoidable factors. The book also discusses the impact of
aging on overall mortality and the strange situation that,
according to official statistics, aging does not exist as cause of
death. This book is a turning point between a gerontology and
geriatrics conceived as the study and vain treatment of an
incurable condition and one in which these disciplines examine the
how and why of a physiological phenomenon that can be modified up
to a possible total control. This means transforming the medical
prevention and treatment of physiological aging from the greatest
failure to the greatest success of medicine.
This book contains a compendium of induced pluripotent stem cells
(iPSCs) articles and reviews concerning state of the art
technologies and how they are being applied to human
neurodevelopmental disorders. With the establishment of effective
technologies to produce iPSCs and their derivatives, like neural
precursors, neurons, and glia, researchers have new platforms to
study neurodevelopmental disorders. iPSC technology enables
researchers to study how human neurons develop in individuals with
neurodevelopmental disorders, providing an unparalleled opportunity
to investigate their etiology. In turn, researchers have now begun
to understand the underlying molecular and cellular pathways that
contribute to human diseases. iPSCs technologies also provide an
emerging tool for future translational studies and disease
classification. The chapters will emphasize how among the diverse
idiopathic and genetic disorders, there are common clinical as well
as cellular and molecular phenotypes.
This book compiles for the first time all the current information
on the electronic monitoring of the feeding behavior of
phytophagous true bugs. It includes state-of-the-art illustrations
of feeding sites on the various plant structures, and examines how
the different feeding strategies are related to the variable
waveforms generated using the electropenetrography (EPG) technique.
Further, the book describes the mouthparts and modes of feeding and
discusses the physical and chemical damage resulting from feeding
activities. Covering in detail all EPG studies developed and
conducted using true bugs published to date, it explores the use of
electronic monitoring of feeding coupled with histological analyses
to improve strategies to control true bugs, from traditional
chemical methods to gene silencing (RNAi).
Light scattering from particles in the nanometric and micrometric
size range is relevant in several research fields, such as aerosol
science and nanotechnology. In many applications, the description
of the optical properties of non-spherical, inhomogeneous particles
is still inadequate or requires demanding numerical calculations.
Lorenz-Mie scattering and effective medium approximations represent
currently the main theoretical tools to model such particles, but
their effectiveness has been recently called into question. This
work examines how the morphology of a particle affects its
scattering parameters from an experimental standpoint, supporting
findings with extensive simulations. The dust content of Antarctic,
Greenlandic, and Alpine ice cores is analysed with a
particle-by-particle approach. Moreover, a study on colloidal
aggregates shows that correlations among the fields radiated by
primary particles are responsible for the poor agreement of
effective medium approximations with experimental results. On the
theoretical side, an interpretation in terms of the structure
factor is given, which satisfactorily describes the data. The
insights of this thesis are relevant for quantifying the
contribution of mineral dust to the radiative energy balance of the
Earth.
Algae are simple, primitive, heterogeneous, autotrophic, eukaryotic
or prokaryotic organisms that lead a symbiotic, parasitic or
free-living mode of life. Microalgae and macroalgae possess great
potential in various fields of application. Microalgae are
ubiquitous and extremely diverse microorganisms that can accumulate
toxic contaminants and heavy metals from wastewater, making them a
superior candidate to become a powerful nanofactory. Algae were
discovered to reduce the presence of metal ions, and afterwards aid
in the biosynthesis of nanoparticles. Since algae-mediated biogenic
nanoparticles are eco-friendly, cost-effective, high-yielding,
speedy and energy-efficient, a large number of studies have been
published on them in the last few years. This book focuses on
recent progress on the utilization of algae for the synthesis of
nanoparticles, their characterization and the possible mechanisms
involved. Bioprospecting Algae for Nanosized Materials describes
the synthesis of algal nanomaterials and its application in various
fields for sustainable development. This book outlines the
procedures to prepare phyconanomaterials, techniques to utilize the
nanomaterials, and applications in agriculture, environment and
medicine.
This book provides a practical guide to the analysis of data from
randomized controlled trials (RCT). It gives an answer to the
question of how to estimate the intervention effect in an
appropriate way. This problem is examined for different RCT
designs, such as RCTs with one follow-up measurement, RCTs with
more than one follow-up measurement, cluster RCTs, cross-over
trials, stepped wedge trials, and N-of-1 trials. The statistical
methods are explained in a non-mathematical way and are illustrated
by extensive examples. All datasets used in the book are available
for download, so readers can reanalyse the examples to gain a
better understanding of the methods used. Although most examples
are taken from epidemiological and clinical studies, this book is
also highly recommended for researchers working in other fields.
We are witnessing an alarming, global biodiversity crisis with an
ongoing loss of species and their habitats. In response, a number
of tools and approaches - including some that are contested - are
being explored and promoted. Biodiversity offsets are one such
approach, and deserve critical examination since the debate
surrounding them has often been oversimplified and lacking
practical evidence. As such, this study presents a refined typology
including seven types of biodiversity offsets and taking into
account different contexts, governance arrangements and drivers. It
draws on a detailed analysis of theoretical concepts to explain the
voluntary implementation of biodiversity offsets using an
internet-based (netnographic) research approach. Furthermore it
builds on a broad global explorative base of 72 practical examples
and presents in-depth case studies for each type. The results
reveal a number of global tendencies that allow recommendations to
be made for different locations, contexts and stakeholders. They
also encourage the expansion of this research field to respond to
the pressing needs of policy and practice.
This open access volume presents state-of-the-art inference methods
in population genomics, focusing on data analysis based on rigorous
statistical techniques. After introducing general concepts related
to the biology of genomes and their evolution, the book covers
state-of-the-art methods for the analysis of genomes in
populations, including demography inference, population structure
analysis and detection of selection, using both model-based
inference and simulation procedures. Last but not least, it offers
an overview of the current knowledge acquired by applying such
methods to a large variety of eukaryotic organisms. Written in the
highly successful Methods in Molecular Biology series format,
chapters include introductions to their respective topics, pointers
to the relevant literature, step-by-step, readily reproducible
laboratory protocols, and tips on troubleshooting and avoiding
known pitfalls. Authoritative and cutting-edge, Statistical
Population Genomics aims to promote and ensure successful
applications of population genomic methods to an increasing number
of model systems and biological questions.
