Reflecting the expertise and perspective of five leading
mammalogists, the fourth edition of Mammalogy: Adaptation,
Diversity, Ecology significantly updates taxonomy, includes a new
chapter on mammalian molecular phylogenetics, and highlights
several recently described species. There are close to 5,500
species in the class Mammalia, including the blue whale-the largest
animal that has ever lived-and the pygmy shrew, which weighs little
more than a penny. The functional diversity of mammals has allowed
them to play critical roles in every ecosystem, whether marine,
freshwater, alpine, tundra, forest, or desert. Many mammal species
are critically endangered and present complex conservation and
management challenges. This book touches on those challenges, which
are often precipitated by overharvesting and habitat loss, as well
as emerging threats, such as the impact of wind turbines and white
nose syndrome on bats and chronic wasting disease on deer. Among
the updates and additions to the fourth edition of Mammalogy are
numerous new photos, figures, and cladograms, over 4,200
references, as well as: a completely new chapter on mammalian
phylogeny and genomics; current taxonomy - including major changes
to orders, suborders, and superfamilies of bats and rodents; an
explanation of the recent inclusion of whales with terrestrial
even-toed ungulates; updates on mammalian structural, functional
adaptations, and fossil history; and, recent advances in our
understanding of phylogeny, biogeography, social behavior, and
ecology; a discussion of two new orders and thirteen newly
recognized extant families It also includes: reflections on the
implications of climate change for mammals; thorough examinations
of several recently described species, including Durrell's vontsira
( Salanoia durrelli) and the Laotian rock rat ( Laonastes
aenigmamus); an explanation of mammalian biomechanics, such as that
seen in lunge feeding of baleen whales; Breakout boxes on unique
aspects of mammals, including the syntax of bat songs, singing
mice, and why there are no green mammals (unless we count
algae-covered sloths). Maintaining the accessible, readable style
for which Feldhamer and his coauthors are well known, this new
edition of Mammalogy is the authoritative textbook on this
amazingly diverse class of vertebrates.
Landraces possess a very large genetic base in population structure
and are dynamic populations of cultivated plants with historical
origin, distinct identity, and without any formal crop improvement.
They are often genetically diverse, locally adapted, and associated
with traditional farming systems. Resistance genes to biotic and
abiotic stress factors, which are especially diversified in
landraces, are of great interest to plant breeders, faced with
global climate challenge. In addition, gene pools made of different
landraces grown in different ecological conditions can be used for
wheat breeding to enhance quality; yield and other desirable
agricultural parameters. An estimated 75% of the genetic diversity
of crop plants was lost in the last century due to the replacement
of high yielding modern varieties. There is, thus, an urgent need
to preserve existing species, not only for posterity but also as a
means to secure food supply for a rising world population. In this
book, we provide an overview of wheat landraces with special
attention to genetic diversities, conservation, and utilization.
The state of Sao Paulo, Brazil, is one of the most densely
populated and developed areas in South America. Such development is
evident both in terms of industrialization and urbanization, as
well as in agriculture, which is heavily based on sugar cane,
Eucalyptus plantations and livestock. This intense land use has
resulted in great alteration of the original land cover and
fragmentation of natural ecosystems. For these reasons, it is
almost a paradox that jaguar, a species that requires large areas
of pristine forest to exist, is still found in some parts of the
state of Sao Paulo. It is possible that wild animals could leave in
coexistence with intense land use, or is it the case that such rare
encounters with large wild animals in Sao Paulo will disappear in
the near future? All ecologists are aware of the problems of
habitat changes caused by humans, but it was not until recent years
that researchers started to consider that the land used for
production could also serve as an important habitat for many
different kinds of wild species. This book is about this new
approach to conservation. It also highlights the important role
that sciences could and should have in this discussion in order to
better understand the problems and propose possible solutions.
This book describes the alarming condition of agriculture in the
Anthropocene, when the ethical conception of agriculture as a
service of common utility for both society and environment has
progressively been marginalized. The ethical utility of agriculture
has been sidetracked with the increasing industrialisation of
society, the involvement of agriculture in the business-as-usual
economy, and the consequential environmental and societal impacts
it has had. Thus, re-establishing a meaningful bridge between
ethics and agriculture is necessary. A relatively new science
(ecology) with both a new epistemological tool (that of the
ecosystem concept), and a unique narrative of sustainable
development, can help bridge this gap. This book focuses on ethics
as a lever for raising scientific, technical, social, economic and
political solutions to adopt in agriculture as a model of symbiotic
relationships between man and nature. It provides a detailed
discussion of the ecological intensification practices in order to
maximize ecological and ethical services, wherein agroecosystems
will follow.
Dokuchaev carried out most of his research in Ukraine. His student
and friend, Volodymyr Vernadsky, went on to create
trans-disciplinary environmental sciences and the concept of Earth
as a living organism, famously taken up by James Lovelock. That
spring of ideas still flows and the researches captured in this
volume are relevant to present-day problems, and not only in
Ukraine. Soils have always been under stress but, in the
Anthropocene, mankind is in the driving seat. As a sequel to Soil
Science Working for a Living: Applications of soil science to
present-day problems, we consider issues of policy as well as soil
genesis, attributes and functions in various environments, natural
and man-made. We consider human impacts on the soil cover through
its use and misuse, highlight methods of research and assessment of
soil quality, and the threats of soil degradation. The
distinguished contributors also describe and propose various
options for evaluation and remediation of degraded soils, drawing
on the latest methods of modelling and cartography as well as
long-term field experiments and long experience. The book will be
invaluable to researchers and practitioners in soil science
including graduate and post-graduate education, academics and
professionals.
The Bahia Blanca Estuary is one of the largest coastal systems in
Atlantic South America. This mesotidal estuary, situated in a sharp
transition between humid subtropical and semiarid climates, has a
unique combination of large interannual climatic variations. The
estuarine area encompasses roughly 2300 square kilometers and is
composed of wide expanses of intertidal flats, salt marshes, and
emerged islands, which create intricate landscape patterns. Natural
environments in the estuary sustain a high concentration of marine
and terrestrial species, including endemic, threatened, and
endangered fish and shorebirds. Puerto Cuatreros, in the inner zone
of the estuary, hosts a permanent marine research station, whose
records span more than 30 years of biophysical variables, and
represent one of the largest time series of ecological data in
South America. Beyond its ecological relevance, the Bahia Blanca
Estuary is under increasing anthropogenic pressure from large urban
settlements, industrial developments and harbors, raising the
question of how to balance conservation and development. The Bahia
Blanca Estuary: Ecology and Biodiversity offers a comprehensive
review of life in the ecosystems of the estuary. The book is
divided into five major sections, the first of which provides a
description of the regional setting and covers key aspects of
estuarine dynamics. The three following sections are dedicated to
different habitat types and, within each section, the chapters are
organized around major functional groups from pelagic and benthic
environments. The fifth and final section covers issues related to
management and conservation. Overall, the book provides essential
and up-to-date reference material on the biodiversity and ecosystem
processes of the Bahia Blanca Estuary, and will appeal to a broad
international audience.
This book presents the phylogeny, taxonomy and biogeography of
freshwater red algae. Its content is divided into five chapters.
The first chapter provides a brief history of freshwater red algal
research, habits and collecting methods, general biogeographic
trends and an overview of the taxonomic/phylogenetic placement of
freshwater taxa. The other four chapters are taxonomic treatments
of non-marine red algae based on taxonomic levels, i.e. classes
within the phylum Rhodophyta, orders within each class, families
within each order, and genera within each family. Descriptions,
phylogenetic data (including numerous trees), geographic range
(maps for most species) and dichotomous keys for identification are
presented. Comprehensive data are provided for more than 220
species.
This book presents research findings and conclusions that has been
developed as algorithms or intelligent new methods solving problems
in the fields of air pollution, climate and health, natural hazards
and risks, water resources, human activities and management and
informatics, remote sensing, high-performance computing and GIS for
environmental monitoring and management. Environmental protection
and disaster risk topics are challenging fields, that scientific
world is trying to address as much as it can. Earthquakes, floods,
fires, droughts, blizzards, dust storms, natural releases of toxic
gases and liquids, diseases and other environmental variations
affect hundreds of millions of people each year. Many disaster
events are triggered by human activities. Dealing with these
problems will require systems thinking and integrating
multidisciplinary science. Actions in these directions are taken
more and more in the recent years by political bodies, NGOs and
scientific groups trying to find sustainable solutions for the
future generations. Every point of view matter when it comes to our
global home - The Planet Earth.
This book looks at the case study of Hachioji as a major transit
hub with a world-class public transportation system in Japan. It
tracks how Tokyo slowly expands into its suburban, rural or
sub-rural districts. It also wants to profile the multiple
identities of a city that is simultaneously an ecological asset, a
heritage locale in addition to a logistics hub. The volume is
probably the first of its kind to analyze the western sector of the
largest city in the world.
This book complies latest advancement in the field of environmental
biotechnology. It focuses on topics that comprises industrial,
environment and agricultural related issues to microbiological
studies and exhibits correlation between biological world and
dependence of humans on it. It is designed into three sections
covering the role of environmental biotechnology in industry,
environmental remediation, and agriculture. Ranging from
micro-scale studies to macro, it covers up a huge domain of
environmental biotechnology. Overall the book portrays the
importance of modern biotechnology technologies in solving the
problems in modern day life. The book is a ready reference for
practicing students, researchers of biotechnology, environmental
engineering, chemical engineering and other allied fields likewise.
