Stripe rust is a foliar disease of wheat (Triticum aestivum L.) caused by the air-borne fungus Puccinia striiformis f. sp. tritici and is present in most regions around the world where commercial wheat is grown. Breeding for durable resistance to stripe rust continues to be a priority, but also is...

We present multiple lines of evidence for years to decade-long changes in the location and
character of volcanic activity at West Mata seamount in the NE Lau basin over a 16 year period, and a hiatus
in summit eruptions from early 2011 to at least September 2012. Boninite lava and...

The pathogenic nematodes Pratylenchus neglectus (Rensch, 1924) Filipjev and Schuurmans Stekhoven, 1941 and Pratylenchus thornei Sher and Allen, 1953 cause severe yield losses in wheat (Triticum aestivum L.). The objectives in this study were to assay a collection of Iranian landrace accessions collected from 12 provinces in Iran to identify...

Understanding the drivers and implications of anthropogenic disturbance of ecological connectivity is a key concern for the conservation of biodiversity and 50 ecosystem processes. Here, we review human activities that affect the movements and dispersal of aquatic organisms, including damming of rivers, river regulation, habitat loss and alteration, human-assisted dispersal...

The Ataspaca prospect is in the Cordillera Occidental, 45 km northwest of Tacna, Peru. Epizonal intrusions satellitic to the Caplina- Ataspaca pluton were emplaced 41 m.y. ago into limestones of the Lower Jurassic Pelado Formation along the northeast-trending Chucchuco fault system. Depths of emplacement ranged from 4.5 to 6.0 km....
The fundamental aim of the Oregon Wave Energy Trust’s (OWET’s) cumulative effects framework is to provide an enduring set of information, presented in an effective way to inform substantial decisions about the future and ongoing management of wave energy developments in the context of the existing and future situation. At...
The Pleistocene Carpinteria basin is an east-trending

subcropping against the unconformity indicate most
of the deformation in the Santa Ynez Range prior...

PATRICK ALLAN JACKSON for the degree of MASTER
The Middle Fork John Day Basin in Northeastern Oregon is prime habitat for spring Chinook salmon and Steelhead trout. In 2008, a major tributary supporting rearing habitat, Big Boulder Creek, was restored to its historic mid-valley channel along a 1 km stretch of stream 800 m upstream of the mouth....
