Nutrient Acquisition by Plants
This is an integrated review of the mechanisms controlling plant nutrient uptake and how plants respond to changes in the environment. Among key topics covered are: soil nutrient bioavailability; root responses to variations in nutrient supply; nitrogen fixation; root architecture; life span; mycorrhizae; responses to climate change. The book helps us understand the mechanisms that govern present-day plant communities and to predict the response of plants to a changing climate.

Big Sagebrush
Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.
Ella Baker and the Black Freedom Movement, Second Edition
One of the most important African American leaders of the twentieth century and perhaps the most influential woman in the civil rights movement, Ella Baker (1903–1986) was an activist whose remarkable career spanned fifty years and touched thousands of lives. A gifted grassroots organizer, Baker shunned the spotlight in favor of vital behind-the-scenes work that helped power the Black freedom struggle. Making her way in predominantly male circles while maintaining relationships with a vibrant group of women, students, and activists, Baker was a national officer and key figure in the NAACP, a founder of the Southern Christian Leadership Conference, and a prime mover in the creation of the Student Nonviolent Coordinating Committee. In this definitive biography, Barbara Ransby chronicles Baker's long and rich career, revealing her complexity, radical democratic worldview, and enduring influence on group-centered, grassroots activism. Beyond documenting an extraordinary life, Ransby paints a vivid picture of the African American fight for justice and its intersections with other progressive struggles worldwide throughout the twentieth century.
