Book Description
Stranded on an alien planet, light years from home, wandering from blistering heat to searing cold, Nils Kruger was not a happy man. So when he met another being - even though it wasn't human - things seemed to be looking up. The alien might be helpless, or it might be dangerous, but one thing was for sure - they stood a better chance for survival if they worked together. But as the two creatures overcame their mutual suspicion, as they worked together, as the language barrier was broken down, Nils came to a terrifying conclusion - this alien was more intelligent than a human. And to it, Nils was the alien

Book Description
This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.

Book Description
In communities throughout precontact Mesoamerica, calendar priests and diviners relied on pictographic almanacs to predict the fate of newborns, to guide people in choosing marriage partners and auspicious wedding dates, to know when to plant and harvest crops, and to be successful in many of life's activities. As the Spanish colonized Mesoamerica in the sixteenth century, they made a determined effort to destroy these books, in which the Aztec and neighboring peoples recorded their understanding of the invisible world of the sacred calendar and the cosmic forces and supernaturals that adhered to time. Today, only a few of these divinatory codices survive. Visually complex, esoteric, and strikingly beautiful, painted books such as the famous Codex Borgia and Codex Borbonicus still serve as portals into the ancient Mexican calendrical systems and the cycles of time and meaning they encode. In this comprehensive study, Elizabeth Hill Boone analyzes the entire extant corpus of Mexican divinatory codices and offers a masterful explanation of the genre as a whole. She introduces the sacred, divinatory calendar and the calendar priests and diviners who owned and used the books. Boone then explains the graphic vocabulary of the calendar and its prophetic forces and describes the organizing principles that structure the codices. She shows how they form almanacs that either offer general purpose guidance or focus topically on specific aspects of life, such as birth, marriage, agriculture and rain, travel, and the forces of the planet Venus. Boone also tackles two major areas of controversy—the great narrative passage in the Codex Borgia, which she freshly interprets as a cosmic narrative of creation, and the disputed origins of the codices, which, she argues, grew out of a single religious and divinatory system.

Book Description
The association between our ancestors and fire, somewhere around six to four million years ago, had a tremendous impact on human evolution, transforming our earliest human ancestor, a being communicating without speech but with insight, reason, manual dexterity, highly developed social organization, and the capability of experimenting with this new technology. As it first associated with and then began to tame fire, this extraordinary being began to distance itself from its primate relatives, taking a path that would alter its environment, physiology, and self-image. Based on her extensive research with nonhuman primates, anthropologist Frances Burton details the stages of the conquest of fire and the systems it affected. Her study examines the natural occurrence of fire and describes the effects light has on human physiology. She constructs possible variations of our earliest human ancestor and its way of life, utilizing archaeological and anthropological evidence of the earliest human-controlled fires to explore the profound physical and biological impacts fire had on human evolution.

Book Description
The Natural Law of Cycles assembles scientific work from different disciplines to show how research on angular momentum and rotational symmetry can be used to develop a law of energy cycles as a local and global influence. Angular momentum regulates small-scale rotational cycles such as the swimming of fish in water, the running of animals on land, and the flight of birds in air. Also, it regulates large-scale rotation cycles such as global currents of wind and water.James H. Bunn introduces concepts of symmetry, balance, and angular momentum, showing how together they shape the mobile symmetries of animals. Chapter 1 studies the configurations of animals as they move in a head-first direction. Chapter 2 shows how sea animals follow currents and tides generated by the rotational cycles of the earth. In chapter 3, Bunn explores the biomechanical pace of walking as a partial cycle of rotating limbs. On a large scale, angular momentum governs balanced shifts in plate tectonics.Chapter 4 begins with an examination of rotational wind patterns in terms of the counter-balancing forces of angular momentum. The author shows how these winds augment the flights of birds during migrations. A final chapter centres on the conservation of energy as the most basic principle of science. Bunn argues that in the nineteenth century the unity of nature was seen in the emergent concept of energy, not matter, as the source of power, including the movements of animals and machines. In each chapter Bunn features environmental writers who celebrate mobile symmetries. This book will interest students, naturalists, and advocates of the environmental movement.

Book Description
The book presents a wide range of techniques for extracting information from satellite remote sensing images in forest fire danger assessment. It covers the main concepts involved in fire danger rating, and analyses the inputs derived from remotely sensed data for mapping fire danger at both the local and global scale. The questions addressed concern the estimation of fuel moisture content, the description of fuel structural properties, the estimation of meteorological danger indices, the analysis of human factors associated with fire ignition, and the integration of different risk factors in a geographic information system for fire danger management.
