This proceedings presents a compilation of 20 manuscripts and five posters summarizing results of research studies and management projects conducted throughout the United States in areas with special natural resource values. Topics include the restoration of various fire dependent forest ecosystems…

Large commercial crops of morels are harvested annually from montane coniferous forests of the Northwestern United States. Although some morels fruit annually in nondisturbed forests, others fruit copiously in areas experiencing fire, insect infestations, tree mortality, and soil disturbance. Many…

Korean pine-broadleaved forests are very biologically diverse. In the Russian Far East, these forests are subject to a high level of use by humans and are systematically influenced by fire. Intensive exploitation in the past has led to a decrease in the resource potential. Sound decisionmaking and…

Bull trout (Salvelinus confluentus) is a species of conservation concern-listed as "threatened" under the Endangered Species Act-throughout its native range in the western United States. The authors were assembled by the Clark Fork River Aquatic Implementation Team, composed of biologists…

Effective population size (Ne) is an important concept in the management of threatened species like bull trout Salvelinus confluentus. General guidelines suggest that effective population sizes of 50 or 500 are essential to minimize inbreeding effects or maintain adaptive genetic variation,…

This comprehensive guide focuses on restoration of small-scale impact caused by human actions in wilderness and backcountry areas. The guide's goals are to: 1) Help practitioners develop plans that thoroughly address the question of whether site restoration is the best management action and, if so…

Technologies for the production of alternative fuels are receiving increased attention owing to concerns over the rising cost of petrol and global warming. One such technology under development is the use of yeasts for the commercial fermentation of xylose to ethanol. Several approaches have been…

Pichia stipitis is widely studied for its capacity to ferment d-xylose to ethanol. Strain improvement has been facilitated by recent completion of the P. stipitis genome. P. stipitis uses CUG to code for serine rather than leucine, as is the case for the universal genetic code thereby limiting the…

We describe the structure, organization, and transcriptional impact of repetitive elements within the lignin-degrading basidiomycete, Phanerochaete chrysosporium. Searches of the P. chrysosporium genome revealed five copies of pce1, a 1,750-nt non-autonomous, class II element. Alleles encoding a…

These proceedings provide a synopsis of the Third Workshop on Genetics of Bark Beetles and Association Microorganisms, which was held May 20-2, 2006 in Asheville, NC. Twenty- five participants from five countries attended the meeting. The proceedings are structured into four parts: Phylogenetics of…
