Urbanizing Flora of Portland, Oregon, 1806-2008.

Second printing with corrections and additions, December 2009.This is an annotated catalog of the vascular flora of Portland and vicinity. It contains 1,553 taxa in 126 families, and compares the historical flora with changes that have occurred since 1925. Sources included additional publications, the herbarium record, and the botanical observations of the authors and contributors. The vascular flora of the Portland-Vancouver area is documented by herbarium specimens and publications dating back to 1806. Urbanization has had inevitable and predictable effects on the region's vegetation. Wetlands have declined locally by 97 percent, coniferous forest by 92 percent, prairie and savanna by 90 percent, riparian and wetland forest by 58 percent, and oak communities of any sort by 40 percent. Open water features declined 49 percent. Old literature and specimens document the floristic composition of some of these vanished habitats.Keywords: Vegetation description, Oregon flora, Vancouver, Washington, Native Plant Society of Oregon, Portland, Oregon, Oregon Flora Project, Botanical collecting, Urban flor

Large-scale association analysis identifies new lung cancer susceptibility loci and heterogeneity in genetic susceptibility across histological subtypes.

Although several lung cancer susceptibility loci have been identified, much of the heritability for lung cancer remains unexplained. Here 14,803 cases and 12,262 controls of European descent were genotyped on the OncoArray and combined with existing data for an aggregated genome-wide association study (GWAS) analysis of lung cancer in 29,266 cases and 56,450 controls. We identified 18 susceptibility loci achieving genome-wide significance, including 10 new loci. The new loci highlight the striking heterogeneity in genetic susceptibility across the histological subtypes of lung cancer, with four loci associated with lung cancer overall and six loci associated with lung adenocarcinoma. Gene expression quantitative trait locus (eQTL) analysis in 1,425 normal lung tissue samples highlights RNASET2, SECISBP2L and NRG1 as candidate genes. Other loci include genes such as a cholinergic nicotinic receptor, CHRNA2, and the telomere-related genes OFBC1 and RTEL1. Further exploration of the target genes will continue to provide new insights into the etiology of lung cancer

Historical and Existing Vascular and Bryophyte Flora, Former Blue Heron Paper Mill, Willamette Falls, Oregon City, Oregon: Technical Memo to Metro

Willamette Falls has long been a focus of botanical interest, but industrial development at the site has limited public access for over a century. The closure of the Blue Heron paper mill on the south bank of the river, and proposed redevelopment of the site, has given planners an opportunity to revisit this part of the falls and identify its current flora. As part of the preconstruction planning process for public access to the Falls, Metro contracted John Christy to document the historical and existing vascular flora on the site, and Philip Gaddis joined us to document the bryophyte flora

White House publicity operations during the Korean War, June 1950 – June 1951

Truman was the first modern president to face the challenge of selling a limited war. Based on a wide range of primary sources, this article explores the impact that the Korean War had on Truman’s publicity operations. Whereas all wars place important new demands on presidents to speak out more frequently and forcefully, limited wars place significant constraints on what presidents can say and do. During the Korean War, Truman refused to go public at key moments, often employed rhetoric that was more restrained than at earlier moments of the Cold War, and shied away from creating new structures to coordinate the official message. Such actions also had important consequences. In 1950-51, they hampered the task of effective presidential communication, and contributed to the war’s growing unpopularity. For the longer term, they demonstrated the difficulties of selling a limited war, and hence place into sharper context the problems that beset Truman’s successors during the subsequent conflict in Vietnam
