The collision of the Indian and Eurasian plates around fifty
million years ago profoundly altered earth's geography and regional
climates. The rise of the Himalaya led to intensification of the
monsoon, the birth of massive glaciers and turbulent rivers, and an
efflorescence of ecosystems along the most extreme elevational
gradient on Earth. When the Ice Age ended, humans became part of
this mix, and today nearly one quarter of the world's population
inhabits its river basins, from Afghanistan to Myanmar. Life in the
Himalaya examines the region's geophysical and biological systems
and explores the past and future of human sustainability in the
mountain's shadow. Maharaj Pandit divides the Himalaya's history
into four phases. During the first, the mountain and its ecosystems
formed. In the second, humans altered the landscape, beginning with
nomadic pastoralism, continuing to commercial deforestation, and
culminating in pockets of resistance to forest exploitation. The
third phase saw a human population explosion, accompanied by road
and dam building and other large-scale infrastructure that degraded
ecosystems and caused species extinctions. Pandit outlines a future
networking phase which holds the promise of sustainable living
within the mountain's carrying capacity. Today, the Himalaya is
threatened by recurrent natural disasters and is at risk of
catastrophic loss of life. If humans are to have a sustainable
future there, Pandit argues, they will need to better understand
the region's geological vulnerability, ecological fragility, and
sociocultural sensitivity. Life in the Himalaya outlines the
mountain's past in order to map a way forward.
This book presents modern approaches for understanding the evolution and diversification of land plants, one of the most exciting areas of plant systematics. It consists of three sections: origin and diversification of primitive land plants; origin and diversification of angiosperms; speciation and mechanisms of diversification. These sections correspond to the three major areas in the evolution of plants. In each section, data from molecular, morphological, and paleontological approaches are presented. Each author introduces recent progress and new findings, and proposes future research. For example, the morphological evolution of reproductive organs, or flowers in angiosperms, is now being clarified from the molecular genetic point of view through the study of regulatory genes such as MADS gene family. With this book, readers can readily understand the state-of-the-art in plant systematics and become aware of prospective future problems.

A modern approach to understanding the evolution and
diversification of land plants, one of the most exciting areas of
plant systematics. It consists of three sections - origin and
diversification of primitive land plants; origin and
diversification of angiosperms; speciation and mechanisms of
diversification - each section corresponding to a major area in
plant evolution. In each case, data from molecular, morphological,
and paleontological approaches are presented, backed by recent
progress and new findings, together with proposals for future
research. A guide to the latest in plant systematics, heightening
awareness of prospective future problems.
How can environmental degradation be stopped? How can it be
reversed? And how can the damage already done be repaired? The
authors of this volume argue that a two-pronged approach is needed:
reducing demand for ecosystem goods and services and better
management of them, coupled with an increase in supply through
environmental restoration."Restoring Natural Capital" brings
together economists and ecologists, theoreticians, practitioners,
policy makers, and scientists from the developed and developing
worlds to consider the costs and benefits of repairing ecosystem
goods and services in natural and socioecological systems. It
examines the business and practice of restoring natural capital,
and seeks to establish common ground between economists and
ecologists with respect to the restoration of degraded ecosystems
and landscapes and the still broader task of restoring natural
capital. The book focuses on developing strategies that can achieve
the best outcomes in the shortest amount of time as it: considers
conceptual and theoretical issues from both an economic and
ecological perspective examines specific strategies to foster the
restoration of natural capital and offers a synthesis and a vision
of the way forwardNineteen case studies from around the world
illustrate challenges and achievements in setting targets, refining
approaches to finding and implementing restoration projects, and
using restoration of natural capital as an economic opportunity.
Throughout, contributors make the case that the restoration of
natural capital requires close collaboration among scientists from
across disciplines as well as local people, and when successfully
executed represents a practical, realistic, and essential tool for
achieving lasting sustainable development."
Faced with widespread and devastating loss of biodiversity in wild
habitats, scientists have developed innovative strategies for
studying and protecting targeted plant and animal species in
"off-site" facilities such as botanic gardens and zoos. Such ex
situ work is an increasingly important component of conservation
and restoration efforts.
Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr.,
Kayri Havens, and Mike Maunder, is the first book to address
integrated plant conservation strategies and to examine the
scientific, technical, and strategic bases of the ex situ approach.
The book examines where and how ex situ investment can best support
in situ conservation. Ex Situ Plant Conservation outlines the role,
value, and limits of ex situ conservation as well as updating best
management practices for the field, and is an invaluable resource
for plant conservation practitioners at botanic gardens, zoos, and
other conservation organizations; students and faculty in
conservation biology and related fields; managers of protected
areas and other public and private lands; and policymakers and
members of the international community concerned with species
conservation.
It has long been recognized that plants and animals profoundly
affect one another's characteristics during the course of
evolution. However, the importance of coevolution as a dynamic
process involving such diverse factors as chemical communication,
population structure and dynamics, energetics, and the evolution,
structure, and functioning of ecosystems has been widely recognized
for a comparatively short time. Coevolution represents a point of
view about the structure of nature that only began to be fully
explored in the late twentieth century. The papers presented here
herald its emergence as an important and promising field of
biological research. Coevolution of Animals and Plants is the first
book to focus on the dynamic aspects of animal-plant coevolution.
It covers, as broadly as possible, all the ways in which plants
interact with animals. Thus, it includes discussions of
leaf-feeding animals and their impact on plant evolution as well as
of predator-prey relationships involving the seeds of angiosperms.
Several papers deal with the most familiar aspect of mutualistic
plant-animal interactions-pollination relationships. The
interactions of orchids and bees, ants and plants, and butterflies
and plants are discussed. One article provides a fascinating
example of more indirect relationships centered around the role of
carotenoids, which are produced by plants but play a fundamental
part in the visual systems of both plants and animals. Coevolution
of Animals and Plants provides a general conceptual framework for
studies on animal-plant interaction. The papers are written from a
theoretical, rather than a speculative, standpoint, stressing
patterns that can be applied in a broader sense to relationships
within ecosystems. Contributors to the volume include Paul Feeny,
Miriam Rothschild, Christopher Smith, Brian Hocking, Lawrence
Gilbert, Calaway Dodson, Herbert Baker, Bernd Heinrich, Doyle
McKey, and Gordon Frankie.
More than eighty years ago, before we knew much about the
structure of cells, Russian botanist Boris Kozo-Polyansky
brilliantly outlined the concept of symbiogenesis, the symbiotic
origin of cells with nuclei. It was a half-century later, only when
experimental approaches that Kozo-Polyansky lacked were applied to
his hypotheses, that scientists began to accept his view that
symbiogenesis could be united with Darwin's concept of natural
selection to explain the evolution of life. After decades of
neglect, ridicule, and intellectual abuse, Kozo-Polyansky's ideas
are now endorsed by virtually all biologists.
Kozo-Polyansky's seminal work is presented here for the first
time in an outstanding annotated translation, updated with
commentaries, references, and modern micrographs of symbiotic
phenomena.
What is the origin of the universe? How did life appear on Earth
and why was much of that life destroyed at various times in Earth's
history? In this book four noted scientists-physicist Alan H. Guth,
astronomer George Wetherill, biologist Lynn Margulis, and
paeleobiologist David Raup- propose answers to these questions,
discussing the newest developments in some exciting areas of
current research. "Comprises four excellent essays. . . . The
authors of this book seek to elucidate the remote, unusual events
that most influenced the history of the cosmos and the earth. They
describe alternative models and the evidence on which these models
are based."-Laurie R. Godfrey, Science Books and Films "For a
scientist who specializes in cosmology and earth history, this book
is a worthwhile documentation of the opinions of four very
different scientists."-G. Ledyard Stebbins, BioScience "Beginning
with a tracing of the universe back to its beginnings, this
fascinating little book presents the current state of knowledge and
recent theories relating to the origins of the universe, our earth
and life on earth. The last chapter explores extinction in our
geologic past. Written by distinguished scientists, all papers
attempt to establish patterns that may characterize other planets
as well as our own."-New Technical Books
