Natural resources and associated biological diversity provide the basis of livelihood for human population, particularly in the rural areas and mountain regions across the globe. Asia is home to the world's highest mountain regions including the Himalayas, Karakorum and Hindukush. These regions are renowned around the globe because of their unique beauty, climate, and biocultural diversity. Because of geoclimatic conditions, the mountains of Asia are medicinal and food plant diversity hot spots. The indigenous communities residing in the valleys of these mountains have their own culture and traditions, and have a long history of interaction with the surrounding plant diversity. Local inhabitants of these mountains areas possess significant traditional knowledge of plant species used as food, medicine, and for cultural purposes. So far, many workers have reported traditional uses of plant species from different regions of Asia including some mountain areas; however, there is not one inclusive document on the ethnobotany of mountains in Asia. This book provides a comprehensive overview on ethno-ecological knowledge and cross cultural variation in the application of plant species among various communities residing in the mountains of Asia; cross cultural variation in traditional uses of plant species by the mountain communities; high value medicinal and food plant species; and threats and conservation status of plant species and traditional knowledge. This book should be useful to researchers of biodiversity and conservation, ethnobiologists, ethnoecologists, naturalists, phytochemists, pharmacists, policy makers, and all who have a devotion to nature.
This book examines sociobiology and evolution from the scientific and philosophical perspectives. Both sociobiology and evolution are areas of modern biology fraught with controversy and misunderstanding, yet fundamental to a coherent view of human life. For scientists and philosophers of science, at issue are the basic underpinnings of biology: explanation, determination, teleology, reductionism, and hierarchy. Professor Dyke describes the controversies involved, and argues that progress in sociobiology and evolution is hindered by an outmoded philosophical view of science - one that does not adequately take into account recent advances in our understanding of basic biological processes. The author aims to shift the focus from a philosophical understanding of biology to a dynamic, philosophically aware science.
This book illustrates the key role played by taxonomy in the conservation and sustainable utilisation of plant biodiversity. It is a tribute to the work of Professor Vernon Heywood who has done so much to highlight the importance of sound scholarship, training and collaboration for plant conservation. Divided into four parts, the book opens with an overview of the place of taxonomy in science and in implementing the Convention on Biological Diversity. Part 2 outlines the theoretical basis of taxonomy, how it is done and how it contributes to measuring diversity. The third part explains how taxonomy is used to establish conservation priorities and actions and the concluding part illustrates taxonomy in the practice and measurement of effective conservation action. With contributions from taxonomists and also the users of taxonomy, the volume will provide a balanced treatment, suitable for advanced students, researchers and conservation professionals.
This fully updated edition explores conceptual as well as technical guidelines for plant taxonomists and geneticists, such as the increasing use of next-generation sequencing (NGS) technologies for numerous applications in plant taxonomy. The volume provides molecular approaches to be used within an "integrative taxonomy" framework, combining a range of nucleic acid and cytogenetic data together with other crucial information (taxonomy, morphology, anatomy, ecology, reproductive biology, biogeography, paleobotany, etc.), which will help not only to best circumvent species delimitation but also to resolve the evolutionary processes in play. Written for the highly successful Methods in Molecular Biology series, 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. Authoritative and up-to-date, Molecular Plant Taxonomy: Methods and Protocols, Second Edition is an ideal guide for researchers seeking a better understanding of evolutionary processes, at species and population level, through molecular techniques.
Microbes are ubiquitous in nature. Among microbes, fungal communities play an important role in agriculture, the environment, and medicine. Vast fungal diversity has been associated with plant systems, namely epiphytic fungi, endophytic fungi, and rhizospheric fungi. These fungi associated with plant systems play an important role in plant growth, crop yield, and soil health. Rhizospheric fungi, present in rhizospheric zones, get their nutrients from root exudates released by plant root systems, which help with their growth, development, and microbe activity. Endophytic fungi typically enter plant hosts through naturally occurring wounds that are the result of plant growth, through root hairs, or at epidermal conjunctions. Phyllospheric fungi may survive or proliferate on leaves depending on material influences in leaf diffuseness or exudates. The diverse nature of these fungal communities is a key component of soil-plant systems, where they are engaged in a network of interactions endophytically, phyllospherically, as well as in the rhizosphere, and thus have emerged as a promising tool for sustainable agriculture. These fungal communities promote plant growth directly and indirectly by using plant growth promoting (PGP) attributes. These PGP fungi can be used as biofertilizers and biocontrol agents in place of chemical fertilizers and pesticides for a more eco-friendly method of promoting sustainable agriculture and environments. This first volume of a two-volume set covers the biodiversity of plant-associated fungal communities and their role in plant growth promotion, the mitigation of abiotic stress, and soil fertility for sustainable agriculture. This book should be useful to those working in the biological sciences, especially for microbiologists, microbial biotechnologists, biochemists, and researchers and scientists of fungal biotechnology.
The question of whether biologists should continue to use the Linnaean hierarchy is a hotly debated issue. Invented before the introduction of evolutionary theory, Linnaeus' system of classifying organisms is based on outdated theoretical assumptions, and is thought to be unable to provide accurate biological classifications. Ereshefsky argues that biologists should abandon the Linnaean system and adopt an alternative that is more in line with evolutionary theory. He illustrates how the continued use of this system hampers our ability to classify the organic world, and then goes on to make specific recommendations for a post-Linnaean method of classification.

Chaetomium genus was established by Gustav Kunze in 1817. According to Index Fungorum Partnership, there are 273 Chaetomium species accepted till now. Members of the genus Chaetomium are capable of colonizing various substrates and are well-known for their ability to degrade cellulose and to produce a variety of bioactive metabolites. More than 200 compounds have been reported from this genus. A huge number of new and bioactive secondary metabolites associated with unique and diverse structural types, such as chaetoglobosins, epipolythiodioxopiperazines, azaphilones, depsidones, xanthones, anthraquinones, chromones, and steroids, have been isolated and identified. Many of the compounds have been reported to possess significant biological activities, such as antitumor, antimalarial, cytotoxic, enzyme inhibitory, antimicrobial, phytotoxic, antirheumatoid and other activities. Chaetomium taxa are frequently reported to be cellulase and ligninase producers with the ability to degrade cellulosic and woody materials. This is the first, comprehensive volume covering Chaetomium genus in detail. It includes the latest research, methods, and applications, and was written by scholars working directly in the field. The book also contains informative illustrations and is fully referenced for further reading.
This book provides a knowledge-based view to the dynamic capabilities in an organization. The author integrates two existing views on gaining competitive advantage: the Knowledge View which suggests that the capability of organizations to learn faster than competitors is the only source of competitiveness; and the Dynamic Capability View which speculates that a fi rm's competitive advantage rests on it's ability to adapt to changes in the business environment. Using the IT sector in India as a case study, this book provides and tests a new framework-Knowledge-Based Dynamic Capabilities-in the prediction of competitive advantage in organizations.

A revised and fully updated edition encourages the reader to view existing classification systems objectively as it reflects upon the rapid advances that have occurred since the first edition's publication.
Taxonomy is an ever-changing, controversial and exCitmg field of biology. It has not remained motionless since the days of its founding fathers in the last century, but, just as with other fields of endeavour, it continues to advance in leaps and bounds, both in procedure and in philosophy. These changes are not only of interest to other taxonomists, but have far reaching implications for much of the rest of biology, and they have the potential to reshape a great deal of current biological thought, because taxonomy underpins much of biological methodology. It is not only important that an ethologist. physiologist. biochemist or ecologist can obtain information about the identities of the species which they are investigating; biology is also uniquely dependent on the comparative method and on the need to generalize. Both of these necessitate knowledge of the evolutionary relationships between organisms. and it is the science of taxonomy that can develop testable phylogenetic hypotheses and ultimately provide the best estimates of evolutionary history and relationships.
We are a weird species. Like other species, we have a culture. But by comparison with other species, we are strangely unstable: human cultures self-transform, diverge, and multiply with bewildering speed. They vary, radically and rapidly, from time to time and place to place. And the way we live - our manners, morals, habits, experiences, relationships, technology, values - seems to be changing at an ever accelerating pace. The effects can be dislocating, baffling, sometimes terrifying. Why is this? In A Foot in the River, best-selling historian Felipe Fernandez-Armesto sifts through the evidence and offers some radical answers to these very big questions about the human species and its history - and speculates on what these answers might mean for our future. Combining insights from a huge range of disciplines, including history, biology, anthropology, archaeology, philosophy, sociology, ethology, zoology, primatology, psychology, linguistics, the cognitive sciences, and even business studies, he argues that culture is exempt from evolution. Ultimately, no environmental conditions, no genetic legacy, no predictable patterns, no scientific laws determine our behaviour. We can consequently make and remake our world in the freedom of unconstrained imaginations. A revolutionary book which challenges scientistic assumptions about culture and how and why cultural change happens, A Foot in the River comes to conclusions which readers may well find by turns both daunting and also potentially hugely liberating.

Written in an accessible style by internationally renowned authors in the field, readers are straightforwardly guided through fundamental principles and terminology. Simple worked examples and easy-to-understand diagrams also help readers navigate complex problems that have perplexed scientists for centuries. This practical guide is an essential addition for advanced undergraduates, postgraduates and researchers in taxonomy, systematics, comparative biology, evolutionary biology and molecular biology.
How does death help us understand the living? Death is more than the last event of life; it is interwoven into our growth, development, protection against disease, and more. It influences the direction of entire species via the cycle of a lifespan, and it involves asking many fascinating questions. How do we differentiate between life and death, though? How do we know when a person, animal, or cell is really dead? How much grey area is there in the science? Why do we age? Can we do anything about it? Scientifically, there's much we can learn about a living thing from its cells. In all living things, cells seem to carry "death" gene programs. Some living organisms have created systems to use these to their own advantage. Humans, for example, use the death of specific cells to hone our immune system and to give us fingernails and hair. Perhaps the most dramatic use occurs during the metamorphosis of insects and frogs. Even single-celled organisms use "quorum sensing" to eliminate some cells to ensure the overall survival of their colony in harsh environments. Thus, there is more to death than just dying. This latest book from science writer Gary C. Howard ties together the many ways that death helps us understand life. He synthesizes the involvement and relation of cells, tissues, organisms, and populations, explaining what happens at the end of life. Between discussions about popular topics such as the ethics of extending life and cell regeneration, Howard also answers fascinating questions about life and death. The resulting book examines how the end of life is determined and what we can learn from this process.
The field of molecular evolution has experienced explosive growth
in recent years due to the rapid accumulation of genetic sequence
data, continuous improvements to computer hardware and software,
and the development of sophisticated analytical methods. The
increasing availability of large genomic data sets requires
powerful statistical methods to analyze and interpret them,
generating both computational and conceptual challenges for the
field.
This book presents current knowledge of the early vertebrates--mainly fish, but including some terrestrial creatures--which lived about 250 to 470 million years ago. The work focuses on anatomical and phylogenetic questions, but includes information on fossil discovery and preparation, as well as the analysis of the characteristics from which their relationships may be reconstructed. The author addresses both new and old problems in the evolution of certain anatomical details and deals briefly with the animals' way of life, extinction, and former distribution. The book is the first in its field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationships, or cladogram, with a selection of characters at each node, and a succinct phylogenetic classification.
This text can be read at many levels. Not least it is an extraordinary inventory - an illustrated summary of all the Earthly creatures that have ever lived. Whatever living thing you come across, from E-coli to an oak tree or an elephant, this book will show you what kind of creature it is, and how it relates to all others. Yet there are far too many creatures to present merely as a catalogue. The list of species already described is vast enough - nearly two million - but there could in reality be as many as 30 million different animals, plants, fungi and protists - and perhaps another 400 million different bacteria and archaea. In the 4000 million years or so since life first began on Earth, there could have been several thousand billion different species. The only way to keep track of so many is to classify - placing similar creatures into categories, which nest within larger categories, and so on. As the centuries have passed, so it has become clear that the different groups are far more diverse than had ever been appreciated. Thus Linneus in the 18th century placed all living things in just two kingdoms, Animals and Plants.
Scaling relationships are a persistent theme in biology. Examples include branching patterns of blood vessels, structural and functional correlates of body size, distribution of body size and abundance among species, and variations in populations within an area or over time. This book, based on a conference at the Santa Fe Institute, brings together many of the most prominent workers in the area to assess our current understanding of scaling relationships at the physiological, biomechanical, and ecological levels.
Now that scientists can sequences genes with relative ease, the relationships among living organisms are becoming better known. Those relationships are summarized as phylogenetic trees. This book reveals how those trees can be used to give insights into diverse fields of biological enquiry including ecology, epidemiology, development, conservation, and the evolutionary process itself.
Designed to help students make better taxonomic judgments, this case book contains exercises and case studies which describe how to recognize similarities and differences in sets of comparative data. It explains interpretation with reference to the various ranks in the Linnean hierarchy.
In his historical perspective on the changes in scientific thought over the last 100 years, Carl N. Degler explores the study of social evolution and the ongoing search for human nature. In Search of Human Nature provides a detailed perspective on the reasons behind the shifting emphasis in social thought from biology, to culture, and again to biology. Degler examines why these changes took place, the evidence and people fostering these changes and why students of human nature decided to accept this momentous change in thought. He suggests varying ideologies as the underlying force behind this shift in the study of social science. From Darwin's theory that human social behaviour has drastically evolved from animals, to the belief that human experience serves as the basic differentiating factor in humans, Degler provides a thorough and captivating examination of the roots of human behaviour.
Western philosophy and religion, James Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Here, Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers. Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Virbrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights.
Human Population Biology is a careful integration of the social and biological sciences, drawing on anthropology, biology, human ecology and medicine to provide a comprehensive understanding of how our species adapts to natural and man-made environments. The book's chapters fall into five parts. In Part I, techniques to adapt and apply large-scale demographic methods to smaller populations, particularly important for studying non-Western populations, are presented. In Part II, the relationship of medical genetics to human adaptability and patterns of disease epidemiology in small, non-Western populations are discussed. In Part III work capacity, climatic stress and nutrition are covered. In Part IV methods for growth assessment and prediction are presented and ageing is addressed. The final section, Part V, presents integrated case studies of human adaptation to high altitude, and patterns of modernization and stress resulting from cultural change. |
