This volume constitutes the most recent and most comprehensive
consideration of the largest family of bony fishes, the Cichlidae.
This book offers an integrated perspective of cichlid fishes
ranging from conservation of threatened species to management of
cichlids as invasive species themselves. Long-standing models of
taxonomy and systematics are subjected to the most recent
applications and interpretations of molecular evidence and
multivariate analyses; and cichlid adaptive radiations at different
scales are elucidated. The incredible diversity of endemic cichlid
species in African lakes is revisited as possible examples of
sympatric speciation and as serious cases for management in complex
anthropogenic environments. Extreme hydrology and bathymetry as
driver of micro-allopatric speciation is explored in the African
riverine hotspot of diversity of the lower Congo River. Dramatic
new molecular evidence draws attention to the complex taxonomy and
systematics of Neotropical cichlids including the crater lakes of
Central America. Molecular genetics, genomics, imaging tools and
field study techniques assess the roles of natural, sexual and kin
selection in shaping cichlid traits and beyond. The complex
behavioral adaptations of cichlids are considered from a number of
sub-disciplines including sensory biology, neurobiology,
development, and evolutionary ecology. Most importantly, this
volume puts forth a wealth of new interpretations, explanatory
hypotheses and proposals for practical management and applications
that will shape the future for these remarkable fishes in nature as
well as their use as models for the study of biology.
This book presents a timely review of the latest advances in
rhizosphere biology, which have been facilitated by the application
of omics tools. It includes chapters on the use of various omics
tools in rhizosphere biology, focusing on understanding plant and
soil microbe interactions. The role of proteomics and metagenomics
in research on symbiotic association is also discussed in detail.
The book also includes chapters on the use of omics tools for the
isolation of functional biomolecules from rhizospheric
microorganisms. The book's respective sections describe and provide
detailed information on important omics tools, such as genomics,
transcriptomics, proteomics, metabolomics and meta-epigenomics. In
turn, the book promotes and describes the combined use of plant
biology, microbial ecology, and soil sciences to design new
research strategies and innovative methods in soil biology. Lastly,
it highlights the considerable potential of the rhizosphere in
terms of crop productivity, bioremediation, ecological engineering,
plant nutrition and health, as well as plant adaptation to stress
conditions. This book offers both a practical guide and reference
source for all scientists working in soil biology, plant pathology,
etc. It will also benefit students studying soil microbiology, and
researchers studying rhizosphere structure.
The lands and waters of the Mid-Atlantic Region (MAR) have changed
significantly since before the 16th century when the Susquehannock
lived in the area. Much has changed since Captain John Smith
penetrated the estuaries and rivers during the early 17th century;
since the surveying of the Mason-Dixon Line to settle border
disputes among Maryland, Pennsylvania, and Delaware during the
middle of the 18th century; and since J. Thomas Scharf described
the physiographic setting of Baltimore County in the late 19th
century. As early as 1881, Scharf provides us with an assessment of
the condition of the aquatic ecosystems of the region, albeit in
narrative form, and already changes are taking place - the
conversion of forests to fields, the founding of towns and cities,
and the depletion of natural resources. We have always conducted
our work with the premise that "man" is part of, and not apart
from, this ecosystem and landscape. This premise, and the
historical changes in our landscape, provide the foundation for our
overarching research question: how do human activities impact the
functioning of aquatic ecosystems and the ecosystem services that
they provide, and how can we optimize this relationship?
The rapid urbanization and industrialization of developing
countries across the globe have necessitated for substantial
resource utilization and development in the areas of Healthcare,
Environment, and Renewable energy. In this context ,this
resourceful book serves as a definitive source of information for
the recent developments in application of microbial enzymes in
various sectors. It covers applications in fermentation processes
and their products, extraction and utilisation of enzymes from
various sources and their application in health and biomass
conversion for production of value added products. Different
chapters discuss various areas of bioprospecting in enzyme
technology, and describe why these are the mainstays for industrial
production of value added products. The rich compilation of the
cutting-edge advances and applications of the modern industrial
based techniques hold feasible solutions for a range of current
issues in enzyme technology. This book will be of particular
interest for scientists, academicians, technical resource persons,
engineers and members of industry. Undergraduate and graduate
students pursuing courses in the area of industrial biotechnology
will find the information in the book valuable. General readers
having interest towards biofuels, enzyme technology, fermented food
and value added products, phytochemicals and phytopharmaceutical
products will also find the book appealing. Readers will discover
modern concepts of enzymatic bioprocess technology for production
of therapeutics and industrial value added products.
Ecotones are dynamic over-lapping boundary areas where major
terrestrial biomes meet. As past studies have shown, and as the
chapters in this book will illustrate, their structure, size, and
scope have changed considerably over the millennia, expanding and
shrinking as climate and/or other driving conditions, also changed.
Today, however, many of them are changing at a rate not seen for a
long time, perhaps largely due to climate change and other
human-induced factors. Indeed ecotones are more sensitive to
climate change than the biomes on either side, and thus may serve
as critical early indicators of future climate change. As ecotones
change, they also redefine the limits of the biomes on either side
by altering their distributions of species because, in addition to
their own endemic species, any ecotone will also have species from
both adjoining biomes. Consequently, they may also be places of
high levels of species interaction, serving as active evolutionary
laboratories, which generate new species that then migrate back
into adjacent biomes. Ecotones Between Forest and Grassland
explores how these ecotones have changed in the past, how they are
changing today, and how they are likely to change in the future.
The book includes chapters from around the world with a special
focus on South American and Neotropical ecotones.
This volume is a study of human entanglements with Nature as seen
through the mode of haunting. As an interruption of the present by
the past, haunting can express contemporary anxieties concerning
our involvement in the transformation of natural environments and
their ecosystems, and our complicity in their collapse. It can also
express a much-needed sense of continuity and relationality. The
complexity of the question-who and what gets to be called human
with respect to the nonhuman-is reflected in these collected
chapters, which, in their analysis of cinematic and literary
representations of sentient Nature within the traditional gothic
trope of haunting, bring together history, race, postcolonialism,
and feminism with ecocriticism and media studies. Given the growing
demand for narratives expressing our troubled relationship with
Nature, it is imperative to analyze this contested ground. "Chapter

This manual brings together information on all phases of seed
handling and presents the results of more than 20 years of studies.
Forest Service field personnel at several experiment stations and
regional offices furnished a backlog of source material for
treatments of individual genera. The manual consists of two main
parts. Part 1 formulates general principles on the various phases
of seed handling from formation of the seed to sowing. Part 2,
which forms the larger part of the manual, provides relatively
detailed but concise information for 444 species and varieties of
trees and shrubs; this includes data on distribution and use,
discussions of seeding habits, methods of seed collection,
extraction and storage, seed germination, and nursery and field
practice.
This book provides a guided approach to the geostatistical
modelling of compositional spatial data. These data are data in
proportions, percentages or concentrations distributed in space
which exhibit spatial correlation. The book can be divided into
four blocks. The first block sets the framework and provides some
background on compositional data analysis. Block two introduces
compositional exploratory tools for both non-spatial and spatial
aspects. Block three covers all necessary facets of multivariate
spatial prediction for compositional data: variogram modelling,
cokriging and validation. Finally, block four details strategies
for simulation of compositional data, including transformations to
multivariate normality, Gaussian cosimulation, multipoint
simulation of compositional data, and common postprocessing
techniques, valid for both Gaussian and multipoint methods. All
methods are illustrated via applications to two types of data sets:
one a large-scale geochemical survey, comprised of a full suite of
geochemical variables, and the other from a mining context, where
only the elements of greatest importance are considered. R codes
are included for all aspects of the methodology, encapsulated in
the R package "gmGeostats", available in CRAN.
This book provides a comprehensive overview of the current state of
knowledge on plant-microbiome interactions and associations. It
covers all major mechanistic approaches used to investigate
microbes' impacts on plant growth promotion, disease control and
health. The industrial manufacture of nitrogen currently accounts
for roughly 2% of the world's total energy consumption. Microbial
products are expected to reduce the need for costly fertilizers, as
well as chemical pesticides and fungicides. While beneficial
microorganisms are increasingly being used in agriculture, abiotic
and biotic stresses such as heat, drought, cold, and salt can
quickly kill or render them useless in the field. However,
discovering new and better treatments is a lengthy process due to
the considerable microbial diversity found in soils. Researchers
have now proposed using biotechnological approaches to accelerate
the process of microbial technology development. The fact that
plant-associated microbes stimulate plant growth and development is
well known, as the examples of rhizobia and mycorrhizal fungi show.
The mechanisms by which these microorganisms maintain plant growth
include the production of phytohormones, fixation of nitrogen, and
the mobilization of phosphorus and minerals. The plant microbiome
is also involved in pathogen suppression, and especially the root
microbiome acts as a protective shield against soil-borne
pathogens. A special feature of this book is its multidisciplinary
approach, spanning from plant microbiology/biocontrol, fungal and
bacterial endophytes, plant physiology, to biochemistry, proteomics
and genomics. It is ideally suited for researchers and student of
agri-biotechnology, soil biology and fungal biology.
This book provides a comprehensive overview of recent research on
estuaries of the east coast of India, and how changing
biogeochemical dynamics as a result of climate change and human
activity have impacted estuaries and other open water ecosystems.
Though estuaries only cover a very small portion of the earth's
hydrosphere, they are some of the most biogeochemically active
regions among the global water bodies. As such, this book focuses
on estuaries of the east coast of India going all the way to the
Bay of Bengal, which is the world's largest freshwater input from
perennial rivers and rain-fed estuaries, and is therefore a unique
area of study. Through its unique coverage of the Bay of Bengal in
particular, the book presents a new perspective not present in the
literature on estuary biogeochemistry and ecosystem dynamics.
Moreover, the book addresses SDG 13 (Climate Action) and 14 (Life
below Water), with a focus on ecosystem services of the natural
aquatic system.The book will be useful to researchers, policy
makers, coastal managers and marine sustainability scientists and
organizations.
This book provides a conceptually organized framework to understand
the phenomenon of biological invasions at the Anthropocene global
scale. Most advances toward that aim have been provided from North
American and European researchers, with fewer contributions from
Australia and South Africa. Here we fill the void from the
Neotropics, focusing on the research experience in South American
countries, with a strong emphasis on Argentina and Chile. The text
is divided into two parts: The first half comprises self-contained
chapters, providing a conceptual, bibliographic and empirical
foundation in the field of invasion biology, from an Anthropocene
perspective. The second half reviews the ecology, biogeography, and
local impacts in South America of exotic species groups (European
rabbit, Eurasian wild boar, Canadian beaver, North American mink,
and Holarctic freshwater fishes), which are shown to be useful
models for case studies of global relevance.
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.
