The Cactaceae family, with about sixteen hundred species, is cultivated worldwide for fruits, forage, fodder, and even as a vegetable. Cacti are recognized for their attractive flowers, special stem shapes, and ability to tolerate drought. Because of their efficient use of water and other adaptations, biological and agronomic interest in cacti has soared.

Described as "a writer in the tradition of Henry David Thoreau, John Muir, and other self-educated seers" by the San Francisco Chronicle, David Rains Wallace turns his attention in this new book to another distinctive corner of California-its desert, the driest and hottest environment in North America. Drawing from his frequent forays to Death Valley, Red Rock Canyon, Kelso Dunes, and other locales, Wallace illuminates the desert's intriguing flora and fauna as he explores a controversial, unresolved scientific debate about the origin and evolution of its unusual ecosystems. Eminent scientists and scholars appear throughout these pages, including maverick paleobiologist Daniel Axelrod, botanist Ledyard Stebbins, and naturalists Edmund Jaeger and Joseph Wood Krutch. Weaving together ecology, geology, natural history, and mythology in his characteristically eloquent voice, Wallace reveals that there is more to this starkly beautiful landscape than meets the eye.

This book provides reviews and primary research articles that discuss the replication, repair, maintenance, and structures of plant organelle genomes. Rearrangements of these genomes are common and provide a way to distinguish closely related plant species. Some articles in the book discuss recent advances in identifying specific proteins and potential mechanisms involved in DNA replication, recombination, and repair in plant mitochondria and chloroplasts.

This book focuses attention on significant novel approaches developed to monitor land surface by exploiting satellite data in the infrared and visible ranges. Unlike in situ measurements, satellite data provide global coverage and higher temporal resolution, with very accurate retrievals of land parameters. This is fundamental in the study of climate change and global warming. The authors offer an overview of different methodologies to retrieve land surface parameters— evapotranspiration, emissivity contrast and water deficit indices, land subsidence, leaf area index, vegetation height, and crop coefficient—all of which play a significant role in the study of land cover, land use, monitoring of vegetation and soil water stress, as well as early warning and detection of forest fires and drought.
