A characterization of seasonal pools in Central Oregon's high desert

Creator:: Dlugolecki, Laura
Abstract:: Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...

Alfalfa cutting management in the Columbia Basin

Creator:: Suttner, Donald Lee
Abstract:: Field studies to determine appropriate cutting management regimes consistent with yield, quality, and persistence of stand were conducted on several alfalfa varieties in the Columbia Basin region of Oregon. Two groups of treatments, including consecutive cuts at the same stage of maturity and cuts made at varying maturities, were imposed...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

The ecology of Lepidurus apus in northern Utah and some limnological requirements for hatching

Creator:: Braswell, Audrey Lee Jr
Abstract:: A survey of the major bodies of water, temporary and perennial, in the region of Northern Utah revealed a limited distribution of the Notostraca. Lepidurus (Linn.), the only representative found, was restricted to a single temporary shallow lake. Dry Lake, in the southern end of Cache County. Dry Lake occupies...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Evolutionary relationships and an investigation of sympatric speciation within Limnanthaceae

Creator:: Meyers, Stephen C.
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Selective control of volunteer wheat (Triticum aestivum (L.) em. Thell.) in new seedlings of alfalfa (Medicago sativa L.) with fluazifop-butyl and sethoxydim

Creator:: Ott, Pablo
Abstract:: Volunteer winter wheat (Triticum aestivum 'Daws') severely suppressed growth of fall-planted alfalfa (Medicago sativa (L.) 'Vernal') seedlings. Wheat competition began soon after alfalfa emerged and continued until the first forage harvest the following May. Alfalfa yield at the first cutting was reduced by 1% for each day volunteer wheat was...
