ABSTRACTTo resolve an inconsistency around AD 1895 between radiocarbon (14C) measurements on oak from the British Isles and Douglas fir and Sitka spruce from the Pacific Northwest, USA, we measured the 14C content in single-year tree rings from a Scots pine tree (Pinus sylvestris L.), which grew in a remote location in Saltdal, northern Norway. The dataset covers the period AD 1864–1937 and its results are in agreement with measurements from the US Pacific coast around 1895. The most likely explanation for older ages in British oak in this period seems to be 14C depletion associated with the combustion of fossil fuels.

Thermodynamic Processes

Abstract. Two Lagrangian tracer tools are evaluated for studies on atmospheric moisture sources and pathways. In these methods, a moisture volume is assigned to each particle, which is then advected by the wind flow. Usual Lagrangian methods consider this volume to remain constant and the particle to follow flow path lines exactly. In a different approach, the initial moisture volume can be considered to depend on time as it is advected by the flow due to thermodynamic processes. In this case, the tracer volume drag must be taken into account. Equations have been implemented and moisture convection was taken into account for both Lagrangian and inertial models. We apply these methods to evaluate the intense atmospheric rivers that devastated (i) the Pacific Northwest region of the US and (ii) the western Iberian Peninsula with flooding rains and intense winds in early November 2006 and 20 May 1994, respectively. We note that the usual Lagrangian method underestimates moisture availability in the continent, while active tracers achieve more realistic results.

Phylogeographic study across codistributed taxa provides temporal and spatial perspectives on the assemblage of communities. A repeated pattern of intraspecific diversification within several taxa of the Pacific Northwest has been documented, and we contribute additional information to this growing data set. We analyzed variation in two mitochondrial genes (cytochrome b and control region) for the black bear (Ursus americanus) and expand previous analyses of phylogeographic variation. Two lineages (coastal and continental) exist; the coastal lineage extends along the Pacific coast from the Takhin River north of Glacier Bay National Park, southeast Alaska, to northern California, whereas the continental lineage is more widespread, occurring from central Alaska to the east coast. Both lineages occur along the coast of southeast Alaska, where interlineage divergence ranged from 3.1 to 3.6% (uncorrected p distances). Multiple lineages of other species have also been identified from southeast Alaska, indicating a complex history for the assembly of biotic communities along the North Pacific coast. The overlapping of the distributions of the black bear lineages with those of other birds and mammals suggests comparable routes of colonization.

Local Politician

The Jefferson Davis Highway (JDH) is a controversial Confederate memorial. Since 1913 the United Daughters of the Confederacy (UDC) have placed markers along roadsides across America to commemorate the Confederate President. The women's organization claims that the JDH stretches over four thousand miles from Alexandria, Virginia to the Pacific coast and the Canadian border. In 2002, conflict ensued in the Pacific northwestern state of Washington when a local politician initiated a campaign to remove a granite JDH marker from a state park where it had been erected by the UDC sixty years previously. This led to dispute over whether Jefferson Davis should, or should not, be honoured by a commemorative marker on Washington's border with Canada. Drawing on contemporary secondary sources to interrogate these contests over the meaning of Jefferson Davis and the Confederate legacy, we argue that behind the veneer of heritage and genealogical celebration forwarded by groups such as the UDC there is a neo-Confederate nationalism that works to maintain white supremacy as a dominant interpretation of US history.

The City

The text presents the preliminary results of the ongoing research on the Polish American community in Seattle, Washington. So far overlooked by the historians of the Polish American experience, the local group differs significantly from other centers of the Polish diaspora in the US. Poles settled in the Pacific Northwest from the late nineteenth century onward, and they developed in the city and around it a strong community that is internally diversified. In Seattle they were confronted with German, Irish, and Jewish groups, as was the case in other American cities, but also with other immigrants, for example with numerous Asians, Nordic people, Croatians, and Bulgarians. Contrary to the patterns of the Polish American community building, there has never been a Polish neighborhood in the city, and the Polish Roman Catholic parish was founded in Seattle as late as 1989. In fact, the parish never gained a crucial importance in the local ethnic community, and presently, as it used to be in the past, the immigrant life is organized around the Polish Home that was launched by the pioneer immigrants in 1918/1920. Many descendants of the earlier immigrant generations participate in the events initiated in Seattle by Poles who arrived in the last decades, and several recent immigrants became involved in the Polish Home Association. Moreover, web platforms – new forms of ethnic connection that developed in the last decades, contribute to the increase of the bonding social capital within the Polish group.

Diverse Groups

In the Pacific Northwest, residents are mobilizing to prevent the coastal export of fossil fuels and protect uniqueecosystems and place-based communities. This paper examines the diverse groups, largely from the Bellinghamarea, and how they succeeded in blocking construction of what was to be the largest coal-shipping port in NorthAmerica, the Gateway Pacific Terminal (GPT). Tribes, environmental organizations, faith-based groups, andother citizen groups used a multitude of approaches to prevent development, both independently and in concert.This paper reviews the various ways in which the groups collaborated and supported one another to resist theneoliberalization of the coast and support local sovereignty, unique ecosystems, and place-based communities.Groups like Power Past Coal, Protect Whatcom, and Coal-Free Bellingham fought for important and protectivechanges and evidenced communitywide political support, but the sovereign rights of the Lummi Nation were thelegal bar to constructing the coal terminal.

This is the first report of stunting, stem distortion, delayed emergence and foliar TRV symptoms on potato in the Pacific Northwest where approximately 50% of the US potato crop is grown. The shift in use from 1,3 dichloropropene to oxamyl may suggest these symptoms will be more frequently observed in the future. Accepted for publication 19 May 2007. Published 17 September 2007.
