"This book introduces bacteria and basic microbiological concepts to readers without previous background in the subject. Each chapter concentrates on a particular topic and can be read in isolation or as part of the whole, and wherever possible points are illustrated through real-world examples and short stories. Although bacterial scientific names are used and translated when possible, in general scientific jargon is avoided in order to make the material as accessible as possible for the lay reader"--

Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions. Because microbes are essential players in the carbon cycle and related processes, microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change. This novel textbook discusses the major processes carried out by viruses, bacteria, fungi, protozoa and other protists - the microbes - in freshwater, marine, and terrestrial ecosystems. It focuses on biogeochemical processes, starting with primary production and the initial fixation of carbon into cellular biomass, before exploring how that carbon is degraded in both oxygen-rich (oxic) and oxygen-deficient (anoxic) environments. These biogeochemical processes are affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predation by various protists in soils and aquatic habitats. The book neatly connects processes occurring at the micron scale to events happening at the global scale, including the carbon cycle and its connection to climate change issues. A final chapter is devoted to symbiosis and other relationships between microbes and larger organisms. Microbes have huge impacts not only on biogeochemical cycles, but also on the ecology and evolution of more complex forms of life, including Homo sapiens..

Published nearly ten years ago, the first edition of Practical Atlas for Bacterial Identification broke new ground with the wealth of detail and breadth of information it provided. The second edition is poised to do the same. Differing fundamentally from the first edition, this book begins by introducing the concept of bacteria community intelligence as reflected in corrosion, plugging, and shifts in the quality parameters in the product whether it be water, gas, oil, or even air. It presents a new classification system for bacterial communities based upon their effect and activities, and not their composition. The book represents a radical departure from the classical reductionist identification of bacteria dominated by genetic and biochemical analyses of separated strains. The author takes a holistic approach based on form, function, and habitat of communities (consorms) of bacteria in real environments. He uses factors related to the oxidation-reduction potential at the site where the consorm is active and the viscosity of the bound water within that consorm to position their community structures within a two-dimensional bacteriological positioning system (BPS) that then allows the functional role to be defined. This book has an overarching ability to define bacterial activities as consorms in a very effective and applied manner useful to an applied audience involved in bacterial challenges. Organized for ease of use, the book allows readers to start with the symptom, uncover the bacterial activities, and then indentify the communities distinctly enough to allow management and control practices that minimize the damage. The broad spectrum approach, new to this edition, lumps compatible bacteria together into a relatively harmonious consortia that share a common primary purpose. It gives a big picture view of the role of bacteria not as single strains but collectively as communities and uses this information to provide key answers to common bacterial problems.

"The authors of this introductory text are acknowledged experts on tropical American orchids with decades of combined experience of orchids in both the wild and culture. You could not find a better trio of enthusiasts and specialists to introduce you to the wonderful and occasionally bizarre world of tropical American orchids."—from the Foreword by Phillip J. Cribb Orchids of Tropical America is an entertaining, informative, and splendidly illustrated introduction to the orchid family for enthusiasts and newcomers seeking to learn about more than 120 widespread orchid genera. Joe E. Meisel, Ronald S. Kaufmann, and Franco Pupulin bring alive the riot of colors, extraordinary shapes, and varied biology and ecology of the principal orchid genera ranging from Mexico and the Caribbean to Bolivia and Brazil. Orchids, likely the most diverse family of plants on earth, reach their peak diversity in the tropical countries of the Western Hemisphere, including, for example, more than 2,500 species in Brazil and 4,000 in Ecuador. The book also highlights reserves in the American tropics where travelers can enjoy orchids in the wild. Whether you journey abroad to see these unique plants, raise them in your home, or admire them from afar, this book offers fascinating insights into the diversity and natural history of orchids. Beyond the plant and flower descriptions, Orchids of Tropical America is packed with informative stories about the ecology and history of each genus. Pollination ecology is given in detail, with an emphasis on how floral features distinctive to the genus are linked to interaction with pollinators. This book also features information on medicinal and commercial uses, notes on the discoverers, and relevant historical data. The easy-to-use identification system permits quick recognition of the most common orchid groups in Central and South America. Genus descriptions are given in plain language designed for a nonscientific audience but will prove highly useful to advanced botanists as well. Descriptions focus on external morphology, and great care has been taken to ensure the guide is useful in the field without reliance on microscopes or dissections. Equally valuable as a field guide, a desktop reference, or a gift, Orchids of Tropical America will make an excellent addition to any orchid lover's library.

It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Every human body carries a secret cargo: a huge population of microorganisms living in the mouth, on the skin, in the gut. They help digest our food. They make essential vitamins. They break down toxins and metabolise drugs. They exert an invisible influence on our hormones, our immune systems, perhaps even our brains. This is the human microbiome – a living, shifting system of previously unimagined importance and complexity. In this first book-length account of this new realm of human biology, award-winning science writer Jon Turney explores the microbiome in detail, charting its birth and development, investigating how it works, and assessing its many implications for our health, including its potential to shed new light on conditions such as bowel diseases, cancer, allergies and asthma. He considers the potential impacts of our modern disinfectant and antibiotic obsessions, and ponders a future of designer microbiomes and mood-altering probiotics. This book will make you think again about your relationship with your body, your habits – even your sense of who and what you are – as it reveals what it means to be a 21st century superorganism.
