Book Description
All animals face the possibility of food limitation and ultimately starvation-induced mortality. This book summarizes state of the art of starvation biology from the ecological causes of food limitation to the physiological and evolutionary consequences of prolonged fasting. It is written for an audience with an understanding of general principles in animal physiology, yet offers a level of analysis and interpretation that will engage seasoned scientists. Each chapter is written by active researchers in the field of comparative physiology and draws on the primary literature of starvation both in nature and the laboratory. The chapters are organized among broad taxonomic categories, such as protists, arthropods, fishes, reptiles, birds, and flying, aquatic, and terrestrial mammals including humans; particularly well-studied animal models, e.g. endotherms are further organized by experimental approaches, such as analyses of blood metabolites, stable isotopes, thermobiology, and modeling of body composition.

Book Description
“Surprising. Impressive. Cannibalism restores my faith in humanity.” —Sy Montgomery, The New York Times Book Review For centuries scientists have written off cannibalism as a bizarre phenomenon with little biological significance. Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we’ve come to accept as fact. In Cannibalism: A Perfectly Natural History,zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism’s role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona’s Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother’s skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own. Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

Book Description
Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Book Description
This important book examines the biology of starvation in humans and other organisms. Topics discussed herein include the physiological landscape of the stationary phase and the molecular events that allow the Mycobacterium smegmatis species to survive prolonged periods of starvation; the biochemical aspects of starvation in yeasts; the epidemiology of hunger in the world and the hunger-obesity paradox; starvation of bacteria for amino acids as an example of prokaryotic response to nutritional deprivation; intra-uterine growth retardation due to maternal undernutrition; and the physiological changes during starvation in fish.

Book Description
A New York Times Book Review Editors' Choice What Saladino finds in his adventures are people with soul-deep relationships to their food. This is not the decadence or the preciousness we might associate with a word like “foodie,” but a form of reverence . . . Enchanting." —Molly Young, The New York Times Dan Saladino's Eating to Extinction is the prominent broadcaster’s pathbreaking tour of the world’s vanishing foods and his argument for why they matter now more than ever Over the past several decades, globalization has homogenized what we eat, and done so ruthlessly. The numbers are stark: Of the roughly six thousand different plants once consumed by human beings, only nine remain major staples today. Just three of these—rice, wheat, and corn—now provide fifty percent of all our calories. Dig deeper and the trends are more worrisome still: The source of much of the world’s food—seeds—is mostly in the control of just four corporations. Ninety-five percent of milk consumed in the United States comes from a single breed of cow. Half of all the world’s cheese is made with bacteria or enzymes made by one company. And one in four beers drunk around the world is the product of one brewer. If it strikes you that everything is starting to taste the same wherever you are in the world, you’re by no means alone. This matters: when we lose diversity and foods become endangered, we not only risk the loss of traditional foodways, but also of flavors, smells, and textures that may never be experienced again. And the consolidation of our food has other steep costs, including a lack of resilience in the face of climate change, pests, and parasites. Our food monoculture is a threat to our health—and to the planet. In Eating to Extinction, the distinguished BBC food journalist Dan Saladino travels the world to experience and document our most at-risk foods before it’s too late. He tells the fascinating stories of the people who continue to cultivate, forage, hunt, cook, and consume what the rest of us have forgotten or didn’t even know existed. Take honey—not the familiar product sold in plastic bottles, but the wild honey gathered by the Hadza people of East Africa, whose diet consists of eight hundred different plants and animals and who communicate with birds in order to locate bees’ nests. Or consider murnong—once the staple food of Aboriginal Australians, this small root vegetable with the sweet taste of coconut is undergoing a revival after nearly being driven to extinction. And in Sierra Leone, there are just a few surviving stenophylla trees, a plant species now considered crucial to the future of coffee. From an Indigenous American chef refining precolonial recipes to farmers tending Geechee red peas on the Sea Islands of Georgia, the individuals profiled in Eating to Extinction are essential guides to treasured foods that have endured in the face of rampant sameness and standardization. They also provide a roadmap to a food system that is healthier, more robust, and, above all, richer in flavor and meaning.
