Population genetic structure of the seed pathogen Pyrenophora semeniperda on Bromus tectorum in western North America.
We examined genetic variation in the ascomycete pathogen Pyrenophora semeniperda cultured from seeds of the invasive grass Bromus tectorum in the Intermountain West of North America. We sequenced the internal transcribed spacer (ITS) region of the nuclear ribosomal RNA genome in 417 monoconidial cultures collected from 20 sites in Washington, Idaho, Utah and Colorado, USA. ITS sequence diversit...
متن کاملDeclining Mountain Snowpack in Western North America*
JANUARY 2005 AMERICAN METEOROLOGICAL SOCIETY | ountain snowpack in western North America is a key component of the hydrologic cycle, storing water from the winter (when most precipitation falls) and releasing it in spring and early summer, when economic, environmental, and recreational demands for water throughout the West are frequently greatest. In most river basins of the West, especially in...
متن کاملPhylogeography of chestnut-backed chickadees in western North America
North American chickadees and titmice are believed to be descendents of Eurasian lineages that crossed the Bering land bridge in the late Pliocene 3.5 to 4 million years ago (Gill et al. 2005; see also Chapters 1 and 2). The North American chickadees are divided into two groups based on phenotypic differences (references in Gill et al. 1989). The black-capped group contains four species: black-...

متن کاملNeurospora in temperate forests of western North America.
The fungal genus Neurospora has a distinguished history as a laboratory model in genetics and biochemistry. The most recent milestone in this history has been the sequencing of the genome of the best known species, N. crassa. The hope and promise of a complete genome sequence is a full understanding of the biology of the organism. Full understanding cannot be achieved, however, in the absence o...
