Juniperus Maritima , the Seaside Juniper , a New Species from Puget Sound , North America
نویسنده
چکیده
Based on analyses of terpenoids, nrDNA and trnC-D SNPs as well as morphology and ecology, a new cryptic species, Juniperus maritima, from the Puget Sound region is recognized. The species, previously included in J. scopulorum, is characterized by having seed cones that mature in one year (14-16 months), seeds usually exserted from the cone, obtuse scale leaf tips, usually reniform seed cones, scale leaves overlap less than 1/5 the length, and branchlets smooth and reddish-brown. Called the seaside juniper, it grows on rocky areas (rarely sand dunes) near the sea, in Puget Sound.

Allopatric hybridization and introgression between Juniperus maritima R. P. Adams and J. scopulorum Sarg. II. Additional Evidence from nuclear and cpDNA genes in Montana, Wyoming, Idaho and Utah
A previous study using data from nrDNA (ITS), maldehy, and petN-psbM (cpDNA) confirmed that allopatric hybridization is occurring at Wallowa, OR, eastern WA, and southeastern BC into western Montana. nrDNA was found to be of less use in detecting hybrids than a single copy nuclear gene (SCN), maldehy. This might to be due to concerted evolution in nrDNA or relictual effects from ancient speciat...
متن کاملGas exchange and carbon isotope discrimination of Juniperus osteosperma and Juniperus occidentalis across environmental gradients in the Great Basin of western North America.
We determined how ecophysiological characteristics of two juniper species, Juniperus occidentalis Hook. (western juniper) and Juniperus osteosperma (Torr.) Little (Utah juniper), changed along altitudinal and regional environmental gradients in the Great Basin of western North America. We obtained diurnal measurements of leaf gas exchange and xylem water potential (Psi) from plants at a low and...

Western juniper (Juniperus occidentalis subsp. occidentalis) range expansion into sagebrush steppe ecosystems has affected both native wildlife and economic livelihoods across western North America. The potential listing of the greater sage-grouse (Centrocercus urophasianus) under the U.S. Endangered Species Act has spurred a decade of juniper removal efforts, yet limited research has evaluated...

Determination of suitable species is the most important factor in success of forestation in unfavorable conditions. One of the least costly and the shortest ways for introduction of adaptable species in an area is recognition of the plants that grow naturally. The objective in this study was to find out the effects of protection and water spreading operations on the quantitative improvement of ...

The genus Juniperus (Cupressaceae) consists of approximately GO species distributed in the orthern Hemisphere, except for J.yrocera Hocll. which extends into the Southern Hemisphere in Africa (Florin, 1963). The delimitation of the species of Juniperus is difficult in all of the world; few taxonomic studies have encompassed any large geographical or natural province. Gaussen (1968) lists 99 spe...
