Discovery and SNPS analyses of populations of Juniperus maritima in the Olympic Peninsula, A Pleistocene refugium?
Adams RP, Hunter G, Fairhall TA. 2010. Discovery and SNPS analyses of populations of Juniperus maritima in the Olympic Peninsula, A Pleistocene refugium?. Phytologia. 92(1):68-81
From the Abstract: "Trees from two populations of Juniperus commonly identified as J. scopulorum growing on the northeast side of the Olympic mountains were analyzed by SNPs from nrDNA and petN-psbM (cpDNA) and compared with J. scopulorum (UT), J. virginiana (TN) and J. maritima from Puget Sound. The trees of the Olympic Mountains were found to be J. maritima. The habitat of these newly investigated populations of J. maritima are atypical in that they occupy high elevation sites (600-1700 m), whereas most previous J. maritima sites are seaside. The Deer Park population (1700 m) plants are Krumholz due to the high winds and snowpack conditions. The Cordilleran ice sheet is mapped and the Olympic peninsula is proposed as the site of a Pleistocene refugium for J. maritima."
