Journal of the Department of Agriculture, Western Australia, Series 4
ALTHOUGH the flora of Western Australia strongly attracted early botanists and collectors, it was virtually neglected by settlers faced with a century or more of hard pioneering.
Only recently has enthusiasm for our remarkable flora developed within the State and, with the formation of sponsoring societies and the establishment of the Kings Park Botanic Gardens, native species have become popular in home and civic gardens.
A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner
Bulletin of the University of Nebraska State Museum (1924–2023)
An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …
The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra
The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra
Bulletin of the University of Nebraska State Museum (1924–2023)
The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

Ornamental Trees For The Farm Garden, P Luff
Journal of the Department of Agriculture, Western Australia, Series 4
THE need for trees in the farm garden is being realized by many people.
Trees around the homestead are required to give such features as shade, colour, fragrance and many other advantages to generally make an area more livable.
Besides these advantages, trees appear to help smaller plants flourish by increasing the humidity and providing various degrees of shade and sunlight.

UNDER natural conditions animals have considerable control over their movements and over their proximity to each other.
Today, however, there is a trend in animal husbandry towards greater intensificaton, and this is most evident in the poultry industry.

The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble
The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble
Bulletin of the University of Nebraska State Museum (1924–2023)
Larandrena contains a single species, A. miserabilis Cresson. This small, common Andrena is found throughout most of the United States and southern Canada in the spring. The subgeneric position, nomenclature, redescription. variation, notes on the biology, parasites, range, seasonal activity and plant host records are included. A. rniserabilis is thought to be an important pollinator of fruit trees.

Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent
Bulletin of the University of Nebraska State Museum (1924–2023)
A new fossil sciurid, Citellus kimballensis, is described. This new species was found in the Kimball Formation, uppermost Ogallala (very late Pliocene) at the University of Nebraska State Museum Collecting Locality Cn-1O1, northeast of Sidney, Cheyenne County, Nebraska. Characters of the dentition and skull of C. kimballensis are compared with those of other species of the genus, and with those of Cynomys.

Development, Verification, And Use Of Methods To Model Chemical And Thermal Processes Lakes Mead And Powell, Bureau Of Reclamation
Publications (WR)
PURPOSE The purpose of the proposed research is to quantify the effects that Lakes Mead and Powell have on the salinity in the Colorado River system, and to evaluate changes that cap be made to the operating system of the reservoirs (within legal/institutional constraints) to enhance salt precipitation and/or minimize evaporation within the reservoirs. The effect of any changes (i.e., selective withdrawal uses, pumped storage, etc.) on reservoir evaporation could also be evaluated with a goal of minimizing evaporation. This will be accomplished through the development of a mathematical model of the reservoirs as described below. BACKGROUND Two major problems …

This study on Microtus montanus was divided into three major sections: 1) An examination of nests, burrows, and runways, 2) A comparison of two methods of home range analysis--live trapping and radio-isotope tracing, and 3) A comparison of the home range of Microtus montanus with other species of Microtus as published in the literature.
Preliminary Studies Of Germination Requirements Of Shadscale Atriplex Confertifolia Torr. And Ferm. Wats, Ijaz Hussain
Preliminary Studies Of Germination Requirements Of Shadscale Atriplex Confertifolia Torr. And Ferm. Wats, Ijaz Hussain
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Shadscale (Atriplex confertilolia (Torr. and Frem.) Wats.) is an important component of the salt-desert-shrub vegetation type in the intermountain region. This species dominates a large portion of the 41 million acres occupied by this vegetation type. Shapscale reaches greatest importance at lower elevations of Utah and Nevada, where despite the low productivity due to its harsh habitat, this vigorous shrub furnishes considerable winter grazing for sheep and cattle. Gates et al. (1966) have observed that poor drainage conditions, coupled with low precipitation, results in the concentration of salts, a chief habitat factor determining the growth and distribution of this species. …

Individual Sow Feeders, P Mcnamara
Journal of the Department of Agriculture, Western Australia, Series 4
FOOD is the major cost in any pig enterprise and it is particularly easy for waste to occur in the breeding herd.
Individual feeders enable the pigman to feed each sow according to her need, and enable the sows to eat their feed slowly or quickly as they choose.

Review Of Silvicultural Research: White Spruce And Trembling Aspen Cover Types, Mixedwood Forest Section, Boreal Forest Region, Alberta-Saskatchewan-Manitoba, J. M. Jarvis, G. A. Steneker, R. M. Waldron, J. C. Lees
Aspen Bibliography
The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …

Factors Affecting Nesting Success Of The Canvasback In The Aspen Parklands, Jerome H. Stoudt
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The Minnedosa study area is located in the southwestern portion of Manitoba just south of the town of Minnedosa. It is 90 square miles in size and roughly square in shape. The Aspen Parkland, in which the study area is located, is characterized by gently rolling terrain and black soils. Mixed farming is the rule with emphasis on small grain production consisting of wheat, barley, and oats. Roughly 50 percent of the water areas in the parkland are ringed with aspen, Populus tremuloides, and large blocks of aspen are interspersed throughout the area. The Minnedosa area differs because of …
