Societies develop as a result of the interactions of individuals as they compete and cooperate with one another in the evolutionary struggle to survive and reproduce successfully. Gorilla society is arranged according to these different and sometimes conflicting evolutionary goals of the sexes. In seeking to understand why gorilla society exists as it does, Alexander H. Harcourt and Kelly J. Stewart bring together extensive data on wild gorillas, collected over decades by numerous researchers working in diverse habitats across Africa, to illustrate how the social system of gorillas has evolved and endured.

Gorilla Society introduces recent theories explaining primate societies, describes gorilla life history, ecology, and social systems, and explores both sexes’ evolutionary strategies of survival and reproduction. With a focus on the future, Harcourt and Stewart conclude with suggestions for future research and conservation. An exemplary work of socioecology from two of the world’s best known gorilla biologists, Gorilla Society will be a landmark study on a par with the work of George Schaller—a synthesis of existing research on these remarkable animals and the societies in which they live.

Early descriptions of the Great Plains often focus on a vast, grassy expanse that was either burnt or burning. The scene continued to burn until the land was plowed under or grazed away and broken by innumerable roads and towns. Yet, where the original landscape has persisted, so has fire, and where people have sought to restore something of that original setting, they have had to reinstate fire. This has required the persistence or creation of a fire culture, which in turn inspired schools of science and art that make the Great Plains today a regional hearth for American fire.

Volume 5 of To the Last Smoke introduces a region that once lay at the geographic heart of American fire, and today promises to reclaim something of that heritage. After all these years, the Great Plains continue to bear witness to how fires can shape contemporary life, and vice versa. In this collection of essays, Stephen J. Pyne explores how this once most regularly and widely burned province of North America, composed of various subregions and peoples, has been shaped by the flames contained within it and what fire, both tame and feral, might mean for the future of its landscapes.

Included in this volume:

• How wildland and rural fire have changed from the 19th century to the 21st century
• How fire is managed in the nation’s historic tallgrass prairies, from Texas to South Dakota, from Illinois to Nebraska
• How fire connects with other themes of Great Plains life and culture
• How and why Texas has returned to the national narrative of landscape fire

Beginning with an overview of how human civilization has altered the face of the Earth, particularly by the destruction of forests, the book details the startling consequences of these actions. Rice provides compelling reasons for government officials, economic leaders, and the public to support efforts to save threatened and endangered plants. Global campaigns to solve environmental problems with plants, such as the development of green roofs and the Green Belt Movementùa women's organization in Kenya that empowers communities worldwide to protect the environmentùshow readers that efforts to save wild plants can be successful and beneficial to the economic well-being of nations.

Through current scientific evidence, readers see that plants are vital to the ecological health of our planet and understand what can be done to lead to a betterùand greenerùfuture

Benefits of plants:

• Help modulate greenhouse gases
• Produce almost all oxygen in the air
• Create cool shade that reduces energy costs
• Prevent floods, droughts, and soil erosion
• Produce all of the food in the world
• Create and preserve soil
• Create natural habitats
• Heal the landscape after natural and human disasters

Few places in the world can claim such a diversity of species as the Gulf of California (Sea of Cortez), with its 6,000 recorded animal species estimated to be half the number actually living in its waters. So rich are the Gulf's water that over a half-million tons of seafood are taken from them annually—and this figure does not count the wasted by-catch, which would triple or quadruple that tonnage. This timely book provides a benchmark for understanding the Gulf's extraordinary diversity, how it is threatened, and in what ways it is—or should be—protected.

In spite of its dazzling richness, most of the Gulf's coastline now harbors but a pale shadow of the diversity that existed just a half-century ago. Recommendations based on sound, careful science must guide Mexico in moving forward to protect the Gulf of California.

This edited volume contains contributions by twenty-four Gulf of California experts, from both sides of the U.S.-Mexico border. From the origins of the Gulf to its physical and chemical characteristics, from urgently needed conservation alternatives for fisheries and the entire Gulf ecosystem to information about its invertebrates, fishes, cetaceans, and sea turtles, this thought-provoking book provides new insights and clear paths to achieve sustainable use solidly based on robust science. The interdisciplinary, international cooperation involved in creating this much-needed collection provides a model for achieving success in answering critically important questions about a precious but rapidly disappearing ecological treasure.
