Book Description
Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. - Presents algae as the important player in relation to environmental health - Prepared by leading authorities in the field - Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms - Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems

Book Description
This volume explores modern concepts of trophic and guild interactions among natural enemies in natural and agricultural ecosystems - a field that has become a hot topic in ecology and biological control over the past decade. It is the first book on trophic and guild interactions to make the link to biological control, and is compiled by internationally recognized scientists who have combined their expertise.

Book Description
"Pinus radiata (radiata pine) is a versatile, fast-growing, medium-density softwood, suitable for a wide range of end-uses. Its silviculture is highly developed, and is built on a rm foundation of over a century of research, observation and practice. Radiata pine is often considered a model for growers of other plantation species. This book explores current knowledge of, and experience with radiata pine forest plantation management and examines its long-term sustainability. Radiata pine management needs to integrate the biological aspects of tree-growing, with socio-economics, management objectives, practical considerations and other constraints and opportunities. Although stands of radiata pine may appear to be simple, they are actually quite complex ecosystems because they contain large, long-lived trees that change dramatically over time and interact in changing ways with the environment and with other organisms. The focus of this book is on the principles and practices of growing radiata pine sustainably. It also looks ahead to emerging challenges facing radiata pine plantation management, such as the effects of climate change, new diseases and other threats, and meeting changing product needs and societal demands."--Page 4 of cover.

Book Description
In recent years, the Confederate flag has become as much a news item as a Civil War relic. Intense public debates have erupted over Confederate flags flying atop state capitols, being incorporated into state flags, waving from dormitory windows, or adorning the T-shirts and jeans of public school children. To some, this piece of cloth is a symbol of white supremacy and enduring racial injustice; to others, it represents a rich Southern heritage and an essential link to a glorious past. Polarizing Americans, these flag wars reveal the profound--and still unhealed--schisms that have plagued the country since the Civil War. The Confederate Battle Flag is the first comprehensive history of this contested symbol. Transcending conventional partisanship, John Coski reveals the flag's origins as one of many banners unfurled on the battlefields of the Civil War. He shows how it emerged as the preeminent representation of the Confederacy and was transformed into a cultural icon from Reconstruction on, becoming an aggressively racist symbol only after World War II and during the Civil Rights movement. We gain unique insight into the fine line between the flag's use as a historical emblem and as an invocation of the Confederate nation and all it stood for. Pursuing the flag's conflicting meanings, Coski suggests how this provocative artifact, which has been viewed with pride, fear, anger, nostalgia, and disgust, might ultimately provide Americans with the common ground of a shared and complex history.
