The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. In the tradition of Jared Diamond’s Guns, Germs, and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

    Weight gain and obesity are driven by hormones—in everyone—and only by understanding the effects of insulin and insulin resistance can we achieve lasting weight loss.In this highly readable and provocative book, Dr. Jason Fung sets out an original, robust theory of obesity that provides startling insights into proper nutrition. In addition to his five basic steps, a set of lifelong habits that will improve your health and control your insulin levels, Dr. Fung explains how to use intermittent fasting to break the cycle of insulin resistance and reach a healthy weight—for good.

    This book shows how easy it is to fill our gardens with everything from foxes, frogs and mice, to butterflies, ladybirds and thousands of fascinating creepy-crawlies.

    The result of thorough research, keen insight, and unassailable common sense, Good Calories, Bad Calories immediately stirred controversy and acclaim among academics, journalists, and writers alike. Michael Pollan heralded it as “a vitally important book, destined to change the way we think about food.” Building upon this critical work in Good Calories, Bad Calories and presenting fresh evidence for his claim, Taubes now revisits the urgent question of what’s making us fat—and how we can change—in this exciting new book. Persuasive, straightforward, and practical, Why We Get Fat makes Taubes’s crucial argument newly accessible to a wider audience.Taubes reveals the bad nutritional science of the last century, none more damaging or misguided than the “calories-in, calories-out” model of why we get fat, and the good science that has been ignored, especially regarding insulin’s regulation of our fat tissue. He also answers the most persistent questions: Why are some people thin and others fat? What roles do exercise and genetics play in our weight? What foods should we eat, and what foods should we avoid? Packed with essential information and concluding with an easy-to-follow diet, Why We Get Fat is an invaluable key in our understanding of an international epidemic and a guide to what each of us can do about it.

    The Hidden Half of Nature reveals why good health—for people and for plants—depends on Earth’s smallest creatures. Restoring life to their barren yard and recovering from a health crisis, David R. Montgomery and Anne Biklé discover astounding parallels between the botanical world and our own bodies. From garden to gut, they show why cultivating beneficial microbiomes holds the key to transforming agriculture and medicine.

    Natasha Campbell-McBride set up The Cambridge Nutrition Clinic in 1998. As a parent of a child diagnosed with learning difficulties, she was acutely aware of the difficulties facing other parents like her, and she has devoted much of her time to helping these families. She realised that nutrition played a critical role in helping children and adults to overcome their disabilities, and has pioneered the use of probiotics in this field.Her willingness to share her knowledge has resulted in her contributing to many publications, as well as presenting at numerous seminars and conferences on the subjects of learning disabilities and digestive disorders. Her book "Gut and Psychology Syndrome" captures her experience and knowledge, incorporating her most recent work.She believes that the link between learning disabilities, the food and drink that we take, and the condition of our digestive system is absolute, and the results of her work have supported her position on this subject. In her clinic, parents discuss all aspects of their child's condition, confident in the knowledge that they are not only talking to a professional but to a parent who has lived their experience. Her deep understanding of the challenges they face, puts her advice in a class of it's own.

    

    Randall never gave sleep much thought. That is, until he began sleepwalking. One midnight crash into a hallway wall sent him on an investigation into the strange science of sleep.In Dreamland, Randall explores the research that is investigating those dark hours that make up nearly a third of our lives. Taking readers from military battlefields to children’s bedrooms, Dreamland shows that sleep isn't as simple as it seems. Why did the results of one sleep study change the bookmakers’ odds for certain Monday Night Football games? Do women sleep differently than men? And if you happen to kill someone while you are sleepwalking, does that count as murder?This book is a tour of the often odd, sometimes disturbing, and always fascinating things that go on in the peculiar world of sleep. You’ll never look at your pillow the same way again.

    In Consilience  (a word that originally meant "jumping together"), Edward O. Wilson renews the Enlightenment's search for a unified theory of knowledge in disciplines that range from physics to biology, the social sciences and the humanities.Using the natural sciences as his model, Wilson forges dramatic links between fields. He explores the chemistry of the mind and the genetic bases of culture. He postulates the biological principles underlying works of art from cave-drawings to Lolita. Presenting the latest findings in prose of wonderful clarity and oratorical eloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions of Newton, Einstein, and Richard Feynman.

    They are the powerhouses of our cells, essential for the production and management of energy at cell level. Dr Sarah Myhill, together with Dr John McLaren Howard of Acumen Laboratories and Dr Norman Booth of Mansfield College Oxford, has spent many years studying the relationship between their malfunction and the commonest problem seen by GPs in the UK – fatigue. Their research findings have been published in three scientific papers in the International Journal of Clinical and Experimental Medicine, in 2009, 2012 and 2013. These studies showed that poor functioning of the mitochondria is the central problem in CFS. Patients with the worst mitochondrial function had the worst fatigue and vice versa. This is solid scientific evidence that CFS is a problem with mitochondria and has allowed the objective measurement of fatigue for the first time. With the publication of the third study, which showed that mitochondrial function tests and symptoms improved in patients who took measures to address their mitochondrial problems, Dr Myhill was ready to write this book. Here she explains the importance of healthy mitochondria, how we can measure their functioning and what we can do to keep them healthy, or restore them to health if problems arise. CFS is all in our cells, not in our minds!

    It can be microscopic, yet also accounts for the largest organisms ever recorded, living for millennia and weighing tens of thousands of tonnes. Its ability to digest rock enabled the first life on land, it can survive unprotected in space, and thrives amidst nuclear radiation.In this captivating adventure, Merlin Sheldrake explores the spectacular and neglected world of fungi: endlessly surprising organisms that sustain nearly all living systems. They can solve problems without a brain, stretching traditional definitions of ‘intelligence’, and can manipulate animal behaviour with devastating precision. In giving us bread, alcohol and life-saving medicines, fungi have shaped human history, and their psychedelic properties, which have influenced societies since antiquity, have recently been shown to alleviate a number of mental illnesses. The ability of fungi to digest plastic, explosives, pesticides and crude oil is being harnessed in break-through technologies, and the discovery that they connect plants in underground networks, the ‘Wood Wide Web’, is transforming the way we understand ecosystems. Yet they live their lives largely out of sight, and over ninety percent of their species remain undocumented.Entangled Life is a mind-altering journey into this hidden kingdom of life, and shows that fungi are key to understanding the planet on which we live, and the ways we think, feel and behave. The more we learn about fungi, the less makes sense without them.

    What it has not done is consider the stark reality that most of the time we humans are thinking about social processes, comparing ourselves to and estimating the intentions of others. In Human, Gazzaniga explores a number of related issues, including what makes human brains unique, the importance of language and art in defining the human condition, the nature of human consciousness, and even artificial intelligence.

    Or should you just ignore this relentless bombardment of medical advice and remember that no one gets out alive.With the same brilliance and humour that bowled us over in "The Great Cholesterol Con", Dr Kendrick takes a scalpel to the world of medical research and dissects it for your inspection. He reveals the tricks that are played to make minute risk look enormous. How the drug trials are hyped, the data manipulated, the endless games that are played to scare us into doing what, in many cases, makes the most money. After reading this book you will know what to believe and what to ignore. You'll have a much greater understanding of the world of medical research. A world in crisis.

    The epidemics of obesity, heart disease, and diabetes are not tied to the overabundance of fat or carbs or any other specific nutrient. Instead, we have been led astray by the growing divide between flavor - the tastes we crave - and the underlying nutrition. Since the late 1940s, we have been slowly leeching flavor out of the food we grow. Those perfectly round, red tomatoes that grace our supermarket aisles today are mostly water, and the big breasted chickens on our dinner plates grow three times faster than they used to, leaving them dry and tasteless. Simultaneously, we have taken great leaps forward in technology, allowing us to produce in the lab the very flavors that are being lost on the farm. Thanks to this largely invisible epidemic, seemingly healthy food is becoming more like junk food: highly craveable but nutritionally empty. We have unknowingly interfered with an ancient chemical language - flavor - that evolved to guide our nutrition, not destroy it.With in-depth historical and scientific research, The Dorito Effect casts the food crisis in a fascinating new light, weaving an enthralling tale of how we got to this point and where we are headed. We've been telling ourselves that our addiction to flavor is the problem, but it is actually the solution. We are on the cusp of a new revolution in agriculture that will allow us to eat healthier and live longer by enjoying flavor the way nature intended.
