Our world is swarming with invisible organisms - bacteria and fungi that affect their hosts and environments in diverse ways. This text looks at the mysterious microscopic world of microbes and investigates how they behave, and why. It tells stories of how scientists have discovered the laws of behaviour of the world of microbes, including the principles of locomotion, navigation, survival, reproduction and communication. In addition, the text relates the behaviour of bacteria and other microbes to our more familiar world and shows their impact on our lives.

Kermit the Frog famously said that it isnÕt easy being green, and in Living at Micro Scale David Dusenbery shows that it isnÕt easy being smallÑexisting at the size of, say, a rotifer, a tiny multicellular animal just at the boundary between the visible and the microscopic. ÒImagine,Ó he writes, Òstepping off a curb and waiting a week for your foot to hit the ground.Ó At that scale, we would be small enough to swim inside the letter O in the word Òrotifer.Ó What are the physical consequences of life at this scale? How do such organisms move, identify prey and predators and (if theyÕre so inclined) mates, signal to one another, and orient themselves? In clear and engaging prose, Dusenbery uses straightforward physics to demonstrate the constraints on the size, shape, and behavior of tiny organisms. While recounting the historical development of the basic concepts, he unearths a corner of microbiology rich in history, and full of lessons about how science does or does not progress. Marshalling findings from different fields to show why tiny organisms have some of the properties they are found to have, Dusenbery shows a science that doesnÕt always move triumphantly forward, and is dependent to a great extent on accident and contingency.

26 habitats to explore, featuring more than 250 animals. Did you know that a sword-billed hummingbird has a beak longer than its body, that a giant anteater's tongue can delve two feet into a termite mound in pursuit of food, or that a lion's mane jellyfish can grow tentacles as long as three buses? See how the most sublime animals on the planet size up and compare them all in one go using the enormous fold-out chart at the back of the book.

Your concrete road map to rapidly grow your business and get your life back! Have you ever wanted to grow your business but held back because of fear that it would take over your life? As an owner, it’s all too common to feel you have to choose between your personal life and the success of your business. But the surprising truth is that the only way to truly scale and grow your company is to reduce its reliance on you. This means that, done right, scaling ensures that you can grow your business without sacrificing your life. Jeff Hoffman, a serial entrepreneur and former CEO in the Priceline (Priceline Yardsale) family of companies, and David Finkel, CEO of Maui Mastermind, a business coaching company with thousands of clients worldwide, offer a concrete road map for rapidly growing your business while also gaining more personal freedom. You’ll not only learn the best strategies to generate growth, but you’ll also get proven insider tips to sustain that growth through sound systems, empowered teams, and intelligent internal controls. Hoffman and Finkel will also show you how to overcome predictable obstacles in any pillar of your business—including sales, operations, and finance—with insight for building better lead-generation systems, managing cash flow, and retaining talent. You’ll learn how to: • Escape the Self-Employment Trap and build a business, not a job. • Systematize your business to reduce costs and increase capacity. • Ensure your company survives the “Hit by a Bus” test. • Uncover your company’s top leverage points (and execution strategies to implement what you discover). • Fund your growth with the seven cash flow commandments. • And much more. Scale offers a game plan to work less and get your business to produce more. Written by two worldclass entrepreneurs who have started, scaled, and successfully exited from multiple businesses, which collectively have generated tens of billions of dollars in sales, it gives you their bottom-line best ideas to effectively grow your company. If you have ever felt stuck in your business, not knowing the best way forward, this book is your mustread guide.

Small-scale fisheries are a major source of food and employment around the world. Yet, many small-scale fishers work in conditions that are neither safe nor secure. Millions of them are poor, and often they are socially and politically marginalized. Macro-economic and institutional mechanisms are essential to address these poverty and vulnerability problems; however, interventions at the local community level are also necessary. This requires deep understanding of what poverty means to the fishers, their families and communities; how they cope with it; and the challenges they face to increase resiliency and improve their lives for the better. This book provides a global perspective, situating small-scale fisheries within the broad academic discourse on poverty, fisheries management and development. In-depth case studies from fifteen countries in Latin America, Europe, South and Southeast Asia, and sub-Saharan Africa, demonstrate the enormously complex ecological, economic, social, cultural and political contexts of this sector. Conclusions for policy-making, formulated as a joint statement by the authors, argue that fisheries development, poverty alleviation, and resource management must be integrated within a comprehensive governance approach that also looks beyond fisheries. The scientific editors, Svein Jentoft and Arne Eide, are both with the Norwegian College of Fishery Science, Faculty of Biosciences, Fisheries and Economics, University of Tromsø, Norway.

This stunning photographic essay opens a new frontier for readers to explore through words and images. Microbial studies have clarified life’s origins on Earth, explained the functioning of ecosystems, and improved both crop yields and human health. Scott Chimileski and Roberto Kolter are expert guides to an invisible world waiting in plain sight.

"This is science writing as wonder and as inspiration." —The Wall Street Journal Wall Street Journal From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in. Visionary physicist Geoffrey West is a pioneer in the field of complexity science, the science of emergent systems and networks. The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science: West found that despite the riotous diversity in mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism’s body. West’s work has been game-changing for biologists, but then he made the even bolder move of exploring his work’s applicability. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. Recently, West has applied his revolutionary work to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune.
