A Best Book of 2020: The Washington Post * NPR * Chicago Tribune * Smithsonian A "remarkable" (Los Angeles Times), "seductive" (The Wall Street Journal) debut from the new cohost of Radiolab, Why Fish Don't Exist is a dark and astonishing tale of love, chaos, scientific obsession, and--possibly--even murder. "At one point, Miller dives into the ocean into a school of fish...comes up for air, and realizes she's in love. That's how I felt: Her book took me to strange depths I never imagined, and I was smitten." --The New York Times Book Review David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. But the more of the hidden blueprint of life he uncovered, the harder the universe seemed to try to thwart him. His specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake--which sent more than a thousand discoveries, housed in fragile glass jars, plummeting to the floor. In an instant, his life's work was shattered. Many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation that he believed would at last protect his work against the chaos of the world. When NPR reporter Lulu Miller first heard this anecdote in passing, she took Jordan for a fool--a cautionary tale in hubris, or denial. But as her own life slowly unraveled, she began to wonder about him. Perhaps instead he was a model for how to go on when all seemed lost. What she would unearth about his life would transform her understanding of history, morality, and the world beneath her feet. Part biography, part memoir, part scientific adventure, Why Fish Don't Exist is a wondrous fable about how to persevere in a world where chaos will always prevail.
In Deep Time, Henry Gee, assistant editor of Nature, shows us that everything we think we know about evolution is wrong. For a long time, popular scientists have told us that by looking at a fossilised bone we could tell whether it belonged to our ancestors or not. This is not true. In Deep Time, Henry Gee, introduces for the first time in the popular science market a new way of thinking that has revolutionised the way that scientists are approaching the past - Cladistics. Cladistics ignores story-telling and authority and proposes a method based on shared characteristics, rather than ancestry and descent. As a result of using this new method Henry Gee is able to show us the wealth of new ideas that is radically altering our notions of the past: Dinosaurs with feathers; why fish developed fingers; what it means to be human.
The protein molecule is the basic building block of every living entity. Its deficiency leads to restricted growth and development of individuals. Globally, such malnutrition is on the rise due to various reasons such as rapid population growth, stagnation of productivity, and ever-rising costs. Millions of people, especially in developing and under-developed countries, suffer from protein malnutrition and the only possible solution is to encourage farmers to grow high-protein food legume crops in their fields for domestic consumption. This, however, could be possible if farmers are provided with new cultivars with high yield, and resistance to major insects, diseases, and key abiotic stresses. The major food legume crops are chickpea, cowpea, common bean, groundnut, lentil, pigeonpea, and soybean. Predominantly, the legume crops are grown under a subsistence level and, therefore, in comparison to cereals and horticultural crops their productivity is low and highly variable. The crop breeders around the globe are engaged in breeding suitable cultivars for harsh and changing environments but success has been limited and not up to needs. With the recent development of new technologies in plant sciences, efforts are being made to help under-privileged farmers through breeding new cultivars which will produce more protein per unit of land area. In this book, the contributors analyze the constraints, review new technologies, and propose a future course of crop breeding programs in seven cold and warm season legume crops.
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 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.
Protozoa may be found in almost every aquatic habitat, each containing dozens of species. The diversity can provide invaluable insights into the nature of the habitat. Protozoa can thus be used to illustrate biological principles. This colour guide makes the identification of individual protozoa easily accessible to students and professionals and provides information on protozoan communities found in different environments by means of a wealth of colour photomicrographs supported by original and detailed line drawings and concise text. The guide has been welcomed by professional practitioners, researchers and instructors, by graduate, undergraduate and secondary level students, in a wide range of disciplines, for its clarity in providing a logical system for learning and recognition, the first step towards understanding and using the protozoan community as a biological indicator of environmental change, pollution and contamination.
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.
White biotechnology, or industrial biotechnology as it is also known, refers to the use of living cells and/or their enzymes to create industrial products that are more easily degradable, require less energy, create less waste during production and sometimes perform better than products created using traditional chemical processes. Over the last decade considerable progress has been made in white biotechnology research, and further major scientific and technological breakthroughs are expected in the future. Fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH), and may be associated with plants (epiphytic, endophytic and rhizospheric). The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and their products (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors, providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest developments and research in white biotechnology with a focus on diversity and enzymes.
This book focuses on the morphology, exine ornamentation and the associated evolutionary trends of crabapple pollen and anatomical developmental patterns. To examine the genetic evolutionary patterns of crabapple pollen traits, we constructed an interval distribution function based on characteristic pollen parameters and used a binary trivariate data matrix (Xi Yi Zi) to reflect the exine ornamentation regularity of the pollen. Our findings should inform the taxonomic status of the genus Malus. Pollen electron micrographs from a total of 26 species and 81 cultivars of Malus were recorded in this book. All 107 figures and 642 scanned pollen images constitute primary data obtained by the authors. The images in this book are clear, three-dimensional, and aesthetically pleasing. They are accompanied with text descriptions and provided a method for the indication of the different types of information that can be expected. This book can provide a reference for scientific researchers, students, and teachers in tertiary institutions that are engaged in research concerning crabapple production.
This revised edition of Bats of Southern and Central Africa builds on the solid foundation of the first edition and supplements the original account of bat species then known to be found in Southern and Central Africa with an additional eight newly described species, bringing the total to 124. The chapters on evolution, biogeography, ecology and echolocation have been updated, citing dozens of recently published papers. The book covers the latest systematic and taxonomic studies, ensuring that the names and relationships of bats in this new edition reflect current scientific knowledge. The species accounts provide descriptions, measurements and diagnostic characters as well as detailed information about the distribution, habitat, roosting habits, foraging ecology and reproduction of each species. The updated species distribution maps are based on 6 100 recorded localities. A special feature of the 2010 publication was the mode of identification of families, genera and species by way of character matrices rather than the more generally used dichotomous keys. Since then these matrices have been tested in the field and, where necessary, slightly altered for this edition. New photographs fill in gaps and updated sonograms aid with bat identification in acoustic surveys. The bibliography, which now contains more than 700 entries, will be an invaluable aid to students and scientists wishing to consult original research.
This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract - stomach, small intestine, caecum and colon - in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.
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.
We have the pleasure to present to you the proceedings of the XIVth congress of the "Association pour l'Etude Taxonomique de la Flore d'Afrique Tropicale" (AETFAT). The XIVth AETFAT congress was held from 22 to 27 August 1994, at the Wageningen International Conference Centre in Wageningen, The Netherlands. The congress was attended by 215 participants, 104 of which came from 28 African countries. During the congress 46 papers and more than 100 posters were presented, the texts of most of which are presented in these Proceedings. The expenses of the congress were covered by grants from the Wageningen Agri- cultural University, the Royal Netherlands Academy of Sciences, and others; see page XVI for a complete list. Funds for the participation of 55 members from Africa came from a number of sponsors, in particular from the Directorate General for International Cooperation, the Technical Centre for Agricultural and Rural Co-operation, the Tropenbos Foundation, and Shell Nederland. We express our sincerest thanks to all contributors. The convenors who organized the symposia, and edited the papers afterwards, are gratefully acknowledged. The editors also acknowledge the valuable help of J.J. Bos and A.J.M. Leeuwenberg, both with preparations in the Organizing Committee, as well as with ftnal editing. The printing was undertaken by Kluwer Academic Publish- ers, in collaboration with A.C. Plaizier.

It includes a comprehensive review of previous track, cladistic and molecular biogeographic analyses and is illustrated with full color maps and vegetation photographs of the respective areas covered. Given its scope, the book will be of interest to students and researchers whose work involves systematic and biogeographic analyses of plant and animal taxa of the Mexican Transition Zone or other transition zones of the world, and to ecologists working in biodiversity conservation, who will be able to appreciate the evolutionary relevance of the Mexican Transition Zone for establishing conservation areas..
Volumes III and IV of this encyclopaedia provide a novel classification of the monocotyledons, a group encompassing plants of most diverse life-forms such as aquatics, terrestrial and epiphytic herbs, and tall trees. Of the 106 families now recognized 104 are treated in the two volumes, while the economically or horticulturally important grass and orchid families are relegated to two subsequent volumes. The classification followed here is based on recent molecular studies as well as on the vast body of information available on this plant group. The wealth and precision of information, but also the keys for the identification of genera and details on their properties, including distribution and diversification, make this work an important source for both the scholar and the practitioner in the fields of pure and applied plant sciences..

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 volume includes treatments of systematics and related topics for both fungi and fungus-like organisms in four eukaryotic supergroups, as well as specialized chapters on nomenclature, techniques and evolution. These organisms are of great interest to mycologists, plant pathologists and others, including those interested in the animal parasitic Microsporidia. Our knowledge of the systematics and evolution of fungi has made great strides since the first edition of this volume, largely driven by molecular phylogenetic analyses. Consensus among mycologists has led to a stable systematic treatment that has since become widely adopted and is incorporated into this second edition, along with a great deal of new information on evolution and ecology. The systematic chapters cover occurrence, distribution, economic importance, morphology and ultrastructure, development of taxonomic theory, classification and maintenance and culture. Other chapters deal with nomenclatural changes necessitated by revisions of the International Code of Nomenclature for algae, fungi and plants, including the elimination of separate names for asexual states, as well as methods for preservation of cultures and specimens, character evolution and methods for ultrastructural study, the fungal fossil record and the impact of whole genomes on fungal studies.
Flora of North America, Volume 3, provides information on many of the most familiar wildflowers and trees in North America. Included are treatments of the buttercup family (Ranunculacaeae), with such plants as delphiniums and columbines, and the poppy family (Papveraceae). Most of the important broadleaf tree species are covered, including the oaks (Fagaceae), elms (Ulmaceae), birches (Betulaceae), walnuts (Juglandaceae), plane trees (Plantanaceae), and magnolias (Magnoliaceae). Many striking families are covered, such as the dutchman's pipe family (Aristochiaceae), and the aquatic families Nymphaeceae (water lilies), and Melumbonaceae (lotus). Identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, phenological information, and other significant biological observations are given for each species. The treatments, written and reviewed by experts throughout the systematic botanical community, are based on original observations of herbarium specimens, and wherever possible, on living plants. These observations are supplemented by critical reviews of the literature.
Fungi belonging to the genera "Trichoderma" and "Gliocladium" are soil-bourne saprophytes which have been used for industrial and agricultural applications for decades. Some strains produce enzymes and antibiotics while others are useful as biological agents for the protections of plants against pathogens. This first volume of two, gives a detailed account of the morphology and taxonomy of "Trichoderma" and "Gliocladium", before disscusing their ecology and basic biology. Molecular biological aspects examined include their genome and gene structure, genetic transformation and asexual genetics. A chapter on safety aspects is also included.
Written by a group of world-renowned virologists, this book reviews all of the most recent advances in rhabdovirology, providing an overiew of the field.
This volume in the "Tertiary Level Biology" series fills a gap in the taxonomic literature by providing a comprehensive survey of the arguments and techniques of systematics as they are applied today to all groups of organisms. It covers the principles of nomenclature and classification, the logic and practice of cladistics, and, in a series of chapters, considers the scope, application, benefits and drawbacks of a wide range of sources of phylogenetically informative character systems, from behaviour and morphology to DNA. There is an emphasis on modern aspects of the subject. This book should be of interest to taxonomists, biochemists and evolutionary biologists at advanced undergraduate and immediate postgraduate levels. |
