Biosystematic studies of the Mimulus moschatus complex in the Pacific Northwest

Creator:: Meinke, Robert James
Abstract:: Populations of an unknown species of Mimulus, herein described as Mimulus hymenophyllus Meinke, were located and studied near Horse Creek, a tributary of the Snake River in eastern Wallowa County, Oregon. The new species is differentiated from its apparent closest relative, Mimulus jungermannioides Suksd., by an annual habit, long petioles,...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Ecological Monitoring of Vascular Plant Resources at the Governor Tom McCall Preserve at Rowena Plateau: Initiation of Long-term Studies for Management.

Creator:: Meinke, Robert J. and Magee, Teresa K.
Abstract:: The bluffs and plateaus of the eastern Columbia River are floristically rich and ecologically intricate. A previous descriptive study of the unique scabland vegetation on the Gov. Tom McCall Preserve at Rowena Plateau in Oregon included delineation of several distinct or intergrading native and non-native vegetation units. In this study...

An Evaluation of Putative Sympatric Speciation within Limnanthes (Limnanthaceae)

Creator:: Meyers, Stephen C., Liston, Aaron, and Meinke, Robert
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies within 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...

Seed viability studies for recovery of Plagiobothrys hirtus (Boraginaceae), the rough popcornflower

Creator:: Wilson, Courtney, Amsberry, Kelly, and Meinke, Robert J.
Abstract:: Plagiobothrys hirtus is Oregon’s top priority for endangered plant species recovery, and the wetlands of Douglas County provide the only habitat for this plant in the world. The goal is to downlist this species from endangered to threatened, and in order to do that, existing populations must be protected, and...

Effects of clay-water interactions on water retention in porous media

Creator:: Lenhard, Robert J. (Robert James)
Abstract:: Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...

A force analysis of directional falling

Creator:: McRae, James Robert
Abstract:: Environmental concerns have prompted the need for reviving an old art: controlled felling. The methods currently used, jacking and lining, present new and varied problems for the faller in today's environment. One of the major concerns of the faller is the purpose of this paper what kind of forces are...

An introduction to the formulation of logging production forecasts by computer models

Creator:: Craig, Robert James
Abstract:: Potentially large savings can be realized within the forest industry by improved machine scheduling, labour scheduling, machine investment, inventory management, and the maximization of wood value. Forecasting must change within the forest industry from Ttguesstimatesll to more efficient production forecasting models. Much work needs to be done with data collection...
