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...

Mixing of chlorophyll from the Middle Atlantic Bight cold pool into the Gulf Stream at Cape Hatteras in July 1993

Creator:: Wood, A. Michelle, Sherry, Nelson D., and Huyer, Adriana, 1945-
Abstract:: In July 1993 we collected hydrographic data and information on chlorophyll distribution on the continental shelf north of Cape Hatteras and across the shelf break at Cape Hatteras. The data show that a warm, transparent mixed layer lies over much colder, euphotic, chlorophyll-rich bottom water on the shelf. This layer...

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...
