Electron And Ion Temperatures—A Comparison Of Ground-Based Incoherent Scatter And Ae-C Satellite Measurements, R F. Benson, P Bauer, L H. Brace, Herbert C. Carlson, J Hagen, W B. Hanson, W R. Hoegy, M R. Torr, R H. Wand, Vincent B. Wickwar

All Physics Faculty Publications

The Atmosphere Explorer-C satellite (AE-C) is uniquely suited for correlative studies with ground-based stations because its on-board propulsion system enables a desired ground station overflight condition to be maintained for a period of several weeks. It also provides the first low-altitude (below 260 km) comparison of satellite and incoherent scatter electron and ion temperatures. More than 40 comparisons of remote and in situ measurements were made by using data from AE-C and four incoherent scatter stations (Arecibo, Chatanika, Millstone Hill, and St. Santin). The results indicate very good agreement between satellite and ground measurements of the ion temperature, the average …

Feed Composition, Animal Nutrient Requirements, And Computerization Of Diets, Paul V. Fonnesbeck, Lorin E. Harris, Leonard C. Kearl

Animal, Dairy, and Veterinary Science Faculty Publications

The Symposium is directed to use feed composition and nutrient requirement information to calculate animal diets. Mathematical models (equations) that describe the utilization of nutrients by animals and the variables affecting animal nutrient requirements is presented. The aim is to use feed information and equations that describe nutrient utilization and animal requirements to formulate the most profitable diet for animals in various physiological states and environments. Methods for solving livestock feeding and management problems are presented.

Grindstone Flat And Big Flat Exclosures - A 41-Year Record Of Changes In Clearcut Aspen Communities, United States Department Of Agriculture, Forest Service

Forestry

Deer browsing prevented aspen regeneration in both uncut stands and small 1/20-hectare clearcuts, even though nearby large burns regenerated successfully. Size of the clearcut or burned area may be critical in determining success of aspen regeneration; areas less than about 2 hectares in size may adversely concentrate deer use. Shrub production was less under deer use and forb production was less under cattle use than on protected areas. More apsen suckers were produced in uncut stands where cattle grazed than in stands protected from grazing, suggesting a possible relationship between sucker initiation and reduced competition from the herbaceous understory. Removal …

Estimating Merchantable Volume And Stem Residue In Four Timber Species: Ponderosa Pine, Lodgepole Pine, Western Larch, Douglas-Fir, United States Department Of Agriculture, Forest Service

Forestry

Presents tables and equations for estimating total cubic volumes of wood, wood residue, and bark for ponderosa pine, lodgepole pine, western larch, and Douglas-fir. Tables represent second-growth trees 80 years old or less, ranging in size from 1-1/2 inches d.b.h. to the maximum diameter measured for the respective species. The equations and tables provide a means for estimating wood bark residue volumes from tops, bole sections, and smaller submerchantable stems. Tables and equations can also be used to estimate total cubic volume for the size classes, species, and locale sampled.

Regeneration And Early Growth On Strip Clearcuts In Lodgepole Pine/Bitterbrush Habitat Type, United States Department Of Agriculture, Forest Service

Forestry

Establishment and growth of seedlings 13 years after strip clearcutting was investigated on a lodgepole pine/bitterbrush habitat type in southwestern Montana. Ingress of new seedlings (all from open-coned lodgepole pine) on areas that had been heavily bulldozer scarified was considerably better than on areas without bulldozer scarification. Seed:seedling ratios (established seedlings) ranged from 625:1 to 2,160:1 on scarified sites, and from 1,876:1 to 6,480:1 on unscarified sites. Only 3 years out of 13 resulted in significant numbers of seedlings being established. Advanced regeneration released by logging was growing as rapidly as seedlings established following logging.

Working sets of nomograms for the 20 NFDRS fuel models are not included. However, an order form for obtaining the needed nomograms is provided. USDA Forest Service General Technical Report INT-39, The National Fire-Danger Rating System--1978 by John E. Deeming, Robert E. Burgan, and Jack D. Cohen, a companion publication, covers the NFDRS background, applications, and general principles of the system.

Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C √ó F index, Hilaria jamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.

Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

The Plasma Line Revisited As An Aeronomical Diagnostic: Suprathermal Electrons, Solar Euv, Electron‐Gas Thermal Balance, Herbert C. Carlson, Vincent B. Wickwar, G P. Mantas

All Physics Faculty Publications

Spectra of plasma wave intensities (kT_p) in the ionosphere over Arecibo are calculated and compared with those from observations of the plasma line intensity. This approach involving directly observed quantities avoids the uncertainties that have plagued past comparisons with photoelectron theory. In addition, careful comparisons in physically relevant segments of the spectra show that any significant increase in the magnitude of the solar EUV flux would lead to a contradiction of the observed plasma wave intensities. Further, the comparisons indicate that resolution of the thermal electron‐gas heat balance problem must be sought through better heat transfer rates (e.g., …

A Survey Of Soil Invertebrates In Two Aspen Forests In Northern Minnesota, T.L. Wagner, W.J. Mattson, J.A. Witter

Aspen Bibliography

Productivity of ecosystems depends to a large extent on the quantity of available nutrients. In natural ecosystems, much of the nutrient stock is unavailable because it is bound in live and dead organic matter. Additions to the pool of available nutrients come from several sources, but the largest and most important one is dead organic matter. Therefore, the productivity of ecosystems is often said to be related to the rate of nutrient release from, or the mineralization of, organic litter (Ghilarov 1971, Satchell 1974).
