Infection Of Engelmann-Spruce Seed By Geniculodendron Pyriforme In Western North America, M W. Wicklow-Howard

T.W. "Doc" Daniel Experimental Forest

Geniculodendron pyriforme Salt was identified and characterized by Salt (1974) as the fungus responsible for germination failure of Sitka spruce [Picea sitchensis (Bong.) Carr.] seed in Canadian and British forest nurseries. It was confirmed that the fungus isolated by Epners (1964) from seed of Pinus resinosa Ait., P. sylvestris L., P. strobus L., and Picea glauca (Moench.) Voss. in Canadian nurseries was the same (Salt, 1974). In addition, Salt (1970) demonstrated that the pathogen can infect seeds of western hemlock [Tsuga heterophylla (Raf.) Sarg.], lodgepole pine (Pinus contorta Doug!. ex Loud.), Japanese larch [Larix leptolepis (Sieb. and Zucc.) Gord.] and …

Nongame Birds Of The Rocky Mountain Spruce- Fir Forests And Their Management, Kimberly G. Smith

T.W. "Doc" Daniel Experimental Forest

Spruce-fir forests in the Rocky Mountains consist mainly of Engelmann spruce and subalpine fir. The breeding avifaunas in these forests show remarkable consistency in composition along a latitudinal gradient from Montana to Arizona and New Mexico, and with avian communities in the Hudsonian life zone in Washington, Oregon, and California. Woodpeckers, corvids, and seed-eating finches are the most common components. Only the Golden Eagle and a few other raptors are threatened or endangered. Few species winter in these high mountain forests. The distribution of many species is controlled primarily by the vegetation physiognomy, a variable under the control of the …

Spider Community Organization : Seasonal Variation And The Role Of Vegetation Architecture, Cynthia L. Hatley, James A. Macmahon

Green Canyon Environmental Research Area, Logan Utah

The relationship between vegetation architecture and spider community attributes were examined in a big sage community. Spiders were separated into guilds using similarities of species' hunting behavior. Shrub architecture was experimentally manipulated in the field by either clippings 50% of the shrub's foliage to decrease foliage density or tying together a shrub's branches to increase foliage density. Shrub perturbations resulted in changes in the number of spider species, spider guilds and guild importance values. The number on spider species and guilds in the tied shrubs were significantly higher than those in the clipped or control shrubs sampled. Spider species diversity …

Family Dollar Watch, Marilyn B. Noyes

The Relationship Of Food Conversion Efficiency And Growth Potential In Juvenile Mosquitofish, Gambusia Affinis, Joseph J. Cech Jr., Michael J. Massingill, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

New information concerning respiratory metabolic rates of juvenile mosquitofish (i = 915 mg 02 kg-1 h-1 at 20° C) was applied to existing data on mosquitofish respiration and combined with findings on growth and food consumption rates to determine percentages of net ingested energy used for growth and respiration over a 10- 35° C temperature range. The energy percentage used by mosquitofish for respiration was minimized at 25-30° C while that used for growth (= food conversion efficiency) was maximized at the same temperature. A calculated growth potential index, derived from an overall energy balance equation, was also maximized at …

Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey

Aspen Bibliography

Annual early spring burning has markedly altered the physiognomy and species composition of aspen parkland vegetation of east-central Alberta. Burning was conducted in April for at least 24 years when soil moisture was normally high. The number of herbaceous species per quadrat doubled while a number of woody species declined slightly.

Aspen Bibliography

The yield of sawn products from aspen (Populus tremuloides Michx.) trees from northern New Mexico and eastern Utah, both in terms of volume and dollar value, was related to trial tree and log grades. Trial grading systems generally allowed separation of trees and logs into different levels of volume and dollar value recovery.

Propagation Of Quaking Aspen (Populus Tremuloides Michx.) From Root Cuttings, Karen Elizabeth Burr

Aspen Bibliography

Lateral root cuttings were collected at five quaking aspen (Populus tremuloides Michx.) clones in Larimer County, Colorado on October 2, 1977 and May 30, 1978. The October 1977 root cuttings were stored eight months in air-tight plastic bags at 0 to 4°C. On June 1, 1978 the stored (October 1977) and the fresh (May 1978) root cuttings were planted in a greenhouse propagation bench. All sprouts that developed were allowed to grow on half of the 10-cm long root cuttings randomly selected as controls. On the remaining half of the root cuttings, designated pruned, all but the tallest sprout were …

Evaluation Of Legibility Of Reflectorized License Plates, C. Earl Israelsen, Ronald V. Canfield

Reports

The rainfall simulator at the Utah Water Research Laboratory, Utah State University, Logan, Utah, was utilized in evaluating various types of license plates. This unique facility enables the production of controlled uniform rainfall inside the laboratory. For this experiment, rainfall rates of 0" (dry), 1/2" and 2" per hour were used to compare reflective performance of reflective sheeting (RS), beads-on-paint (BOP), and new paint (NP) license plates under dark nighttime conditions. Both new and used license plates were evaluted. The three types of new plates were made and embossed at the Idaho State Prison using stanard state manufacturing procedures. The …

Computer-Aided Design Of Optimal Infrared Detector Preamplifiers, D. Gary Frodsham, Doran J. Baker

Space Dynamics Laboratory Publications

A mathematical model is given for a frequency-compensated detector/preamplifier appropriate for cryogenically-cooled infrared sensors operating under low background conditions. By use of a digital computer, this model is used to rapidly select the optimal combination of design values. These parameters include load resistance, compensation resistance, compensation capacitance, chopping frequency and detector area to meet desired specifications of noise equivalent power, frequency response, dynamic range, and level of output noise. This computer-aided optimal design approach is demonstrated using a contemporary infrared sensor application.
