  The story of how Yellowstone, established in 1872 as the world’s first national park, has become synonymous with nature conservation—and an examination of today’s challenges to preserve the region’s wilderness heritage. For more than 150 years, the Yellowstone region—now widely known as the twenty-three million acre Greater Yellowstone Ecosystem—has played a prominent role in the United States’ nature conservation agenda. In this book, Robert B. Keiter, an award-winning public land law and policy expert, traces the evolution and application of fundamental ecological conservation concepts tied to Yellowstone.
   
  
  Keiter’s book highlights both the conservation successes and controversies connected with this storied region, which has been enmeshed in change. 
  But in the face of explosive human population growth and related development pressures, new efforts must also account for the region’s privately owned lands along with accelerating recreational activities that present quite different problems.
  
  Exploring both notable conservation accomplishments and the ongoing challenges confronting this special place, Keiter’s book explains the many forces—scientific, political, economic, legal, cultural, climatic, and more—at work driving controversy and change across the region. But more than this, Conserving Nature in Greater Yellowstone shows us that the lessons gleaned from Yellowstone’s expansive nature conservation efforts are profoundly important for both the country and the world.

  Aztec Astronomy and Astrology:...

  Nearly 500 years after the Spanish conquered their mighty empire, the Aztecs are often remembered today for their major capital, Tenochtitlan, as well as being fierce conquerors of the Valley of Mexico who often engaged in human sacrifice rituals. Unlike the Maya, the Aztecs are not widely viewed or remembered with nuance, in part because their own leader burned extant Aztec writings and rewrote a mythologized history explaining his empire’s dominance less than a century before the Spanish arrived. Naturally, Cortes and other Spaniards depicted the Aztecs as savages greatly in need of conversion to Catholicism. While the Maya are remembered for their astronomy, numeral system, and calendar, the Aztecs have primarily been remembered in a far narrower way, despite continuing to be a source of pride to Mexicans through the centuries. 
  	For the Aztec, astronomy was not a purely scientific pursuit but intimately linked to religious, mythological, and ideological elements that were of the highest importance. The celestial realm held a sacred nature, as did the many gods and goddesses that dwelt there, so for all Mesoamerican cultures, astronomy was a fundamental part of their daily lives. Thus, astronomy was present in their calendars, religion, and even agriculture, and in close relation to astronomy, the concept of time was also an essential part of their worldview. The Aztec recorded many of the astronomical events they observed in codices and hieroglyphic inscriptions, but the main evidence of their deep astronomical knowledge comes from their calendar system. This information was then used to plan the orientation of buildings and ceremonial centers, which were aligned to sunrises or sunsets corresponding to special dates, such as solstices or equinoxes. Observational calendars were also used to schedule agricultural activities, as well as rituals, festivals, and celebrations, on an annual cycle.

  To Everything a Season is a beautifully crafted personal and reflective account of many years of the changing seasons, from autumn    to autumn, in and around a village on the edge of the Cambridge Fenland. It is an uplifting reflection about change: what was, what is, what will be.   
  It is about the miracle of the rich gift of life. It is also about death, loss, and the rebirth of the old into something rich and strange.   
  But it is also a book suffused with a gentle humour, with a deep love and sympathy for our fellow creatures. Charles Moseley tackles what we have done to the world of which we are not owners or masters but stewards, not only for our children but for the whole web of life on which everything depends.

  Space Piracy is a forward-thinking resource that considers, analyzes, and provides solutions to the influence of the ignoble side of humanity in the realm of outer space, where potential for crime, corruption, piracy, and war increases as the exploitation of space as a commercial resource continues to develop. This book blends the authors' knowledge with that of subject matter experts to deliver a holistic understanding of criminality in space and help listeners broaden their horizons beyond their own area of specialization. 
   
   
   
  Some of the topics explored in this insightful book include space hacking, from software, data, network, and hardware risks to existing cybersecurity standards and practices in space; criminal organizations that might pursue criminal activities in space, including cartels, kidnappers and devicenappers, and governments; and laws and treaties relevant to space crime, such as the Communications Satellite Act and the Outer Space Treaty of 1967. 
   
   
   
  Filled with practical, thought-provoking knowledge and guidance, Space Piracy earns a well-deserved spot on the bookshelves of professionals working in the best of humanity's institutions, including law and intelligence services, finance, insurance and risk management, corporations, and the sciences, who seek to combat what the worst of us may be dreaming up.

  When Derek Yu released Spelunky for free in 2008, his roguelike-inspired platformer took the indie game community by storm with its combination of classic platform mechanics, extreme difficulty, and random level generation. Four years later, Spelunky's HD remake went on to become PC Gamer's Game of the Year and earn perfect scores from Polygon and Eurogamer. But how is a "perfect" game made? 
   
    
   
  Spelunky is Boss Fight's first autobiographical book: the story of a game's creation as told by its creator. Using his own game as a vehicle, Derek Yu discusses such wide-ranging topics as randomization, challenge, indifferent game worlds, player feedback, development team dynamics, and what's required to actually finish a game. Grab some ropes, a mattock, and your favorite pug—this book is going to dig deep.
