Book excerpt: S2Bark beetles, primarily the peach bark beetle, Phlosotribus liminoris (Harris), are the major cause of gum spots in sawtimber-size black cherry, Prunus serotina Ehrh. Approximately 90 percent of all gum spots in the bole sections are caused by bark beetles. Gum spots were studied in 95 black cherry trees near Parsons, West Virginia. Over 50 percent of the bark beetle-caused gum spots occurred during the first 2 years following partial harvest cuts. Cambium miners, Phytobia pruni (Gross), peach tree borers, Synanthedon pictipes (Grote and Robinson) and S. exidiosa (Say) caused little degrade in the quality zone of veneer logs or in factory grade 1 and 2 sawlogs.

Available in PDF, EPUB and Kindle. Book excerpt: Long-term recreation planning requires an understanding of recreation participation patterns. This study examined Vermonters' participation in 27 leisure activities from three domains (outdoor, resource based, and indoor) to see how such participation differed in each domain. Indoor activities were the most popular, followed by resource-based activities and general outdoor activities. Overall participation declined with age, though this effect was mitigated somewhat for older parents. Other socioeconomic and demographic variables had limited effects on participation.

Book excerpt: This work presents a definitive interpretation of the current status of and future trends in natural products—a dynamic field at the intersection of chemistry and biology concerned with isolation, identification, structure elucidation, and chemical characteristics of naturally occurring compounds such as pheromones, carbohydrates, nucleic acids, and enzymes. With more than 1,800 color figures, Comprehensive Natural Products II features 100% new material and complements rather than replaces the original work (©1999). Reviews the accumulated efforts of chemical and biological research to understand living organisms and their distinctive effects on health and medicine Stimulates new ideas among the established natural products research community—which includes chemists, biochemists, biologists, botanists, and pharmacologists Informs and inspires students and newcomers to the field with accessible content in a range of delivery formats Includes 100% new content, with more than 6,000 figures (1/3 of these in color) and 40,000 references to the primary literature, for a thorough examination of the field Highlights new research and innovations concerning living organisms and their distinctive role in our understanding and improvement of human health, genomics, ecology/environment, and more Adds to the rich body of work that is the first edition, which will be available for the first time in a convenient online format giving researchers complete access to authoritative Natural Products content
