Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.

This book reviews and summarizes the studies on the fish diversity of Japan. It covers the present knowledge of ichthyofauna, habitat distribution, phylogeography, ecology, morphology, and conservation, as well as the history of ichthyology and fish collections in Japan. The book comprises five parts: I. Fish Diversity and Ichthyology of Japan, II. Habitat Distribution and Species Diversity, III. Diversity within Species: Phylogeographic Perspective on Japanese Fishes, IV. Morphological and Ecological Diversifications, and V. Conservation of Fish Diversity in Japan. The Japanese Archipelago is surrounded by two major warm and one cold currents. It is located in the western North Pacific and encompasses several climatic regimes from north to south. Although the land area of Japan is small, the Exclusive Economic Zone (EEZ) of Japan ranks as the sixth largest in the world, including several marginal seas (Sea of Okhotsk, Sea of Japan, and East China Sea), and deep trenches (Izu-Ogasawara, Japan, and Kurile Trenches). Owing to a variety of marine habitats and a complex geological history, Japan has a rich fish species diversity, representing over 4,500 species in 370 families. The richness of fish species diversity has attracted many scientists since the late 1700s, and continuous studies have led to the development of ichthyology in Japan. With chapters written by leading experts in the field, the book will provide a stimulating and reliable resource for future research and contribute to the progress of ichthyology of the world.

As the world population grows, so does the demand for food, putting unprecedented pressure on agricultural lands. In many desert dryland regions, however, intensive cultivation is causing their productivity to decline precipitously. "Rewilding" the least productive of these landscapes offers a sensible way to reverse the damage, recover natural diversity, and ensure long-term sustainability of remaining farms and the communities they support. This accessibly written, groundbreaking contributed volume is the first to examine in detail what it would take to retire eligible farmland and restore functioning natural ecosystems. The lessons in Rewilding Agricultural Landscapes will be useful to conservation leaders, policymakers, groundwater agencies, and water managers looking for inspiration and practical advice for solving the complicated issues of agricultural sustainability and water management.
