Tenebrionidae Beetles Of The Nevada Test Site, Vasco M. Tanner, Willis A. Packham Feb 1965

Tenebrionidae Beetles Of The Nevada Test Site, Vasco M. Tanner, Willis A. Packham

Brigham Young University Science Bulletin, Biological Series

The intent of this study conducted over a period of three years was to ( 1 ) provide descriptions of the species of tenebrionids found at the Nevada Test Site, (2) determine their relative abundance, (3) determine their seasonal activity, and (4) ascertain their plant community relationships.

A total of 14,650 beetles representing 46 kinds of tenebrionids was collected with sunken can traps, by hand, and ultra-violet light. Collections were made at regular intervals in the following plant communities: Larrea-Franseria, Lycium, Atriplex-Kochia, Grayia-Lycium (disturbed and undisturbed areas), Salsola, Coleogyne, Pinyon-Juniper, and Mixed.

The data obtained from this study indicate that …

Damage Caused By Hormone-Like Herbicides, G R W Meadly Jan 1965

Damage Caused By Hormone-Like Herbicides, G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

THE discovery of the selective action of herbicides such as 2,4-D and MCPA resulted in a rapid expansion in the use of these chemicals for agricultural purposes, particularly for the control of weeds in cereal crops.


Clover Disease Of Sheep In Western Australia, A B. Beck, M. R. Gardiner Jan 1965

Clover Disease Of Sheep In Western Australia, A B. Beck, M. R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

DURING the past five years there has been a marked increase in the incidence of breeding abnormalities of sheep associated with the grazing of subterranean clover pastures.

This complex of diseases first became a major problem in Western Australia in the years following 1940 and eventually became known as "clover disease".

Presettlement Vegetation And Vegetational Change In Three Valleys In Central Utah, Earl M. Christensen, Hyrum B. Johnson Aug 1964

Presettlement Vegetation And Vegetational Change In Three Valleys In Central Utah, Earl M. Christensen, Hyrum B. Johnson

Brigham Young University Science Bulletin, Biological Series

Historical information, survey records, and relict vegetation were used as sources of data for determining the nature of the presettlement vegetation of Pavant, Round, and Juab Valleys in central Utah. The foothills were covered with bunch grasses (principally Agropyron spicatum and Poa secunda), scattered junipers (Juniperus utahensis), and sagebrush (Artemisia tridentate). Western wheatgrass (Agropyron smithii) was common on level areas within the foothills. Below the foothill region on the more gentle slopes and benchlands there was a broad belt dominated by bunch grasses. The grassy area intergraded into a zone dominated by northern …

Influence Of Sodium And Calcium Chlorides In The Nutrient Solution On Secretions Of Salt Glands Of Tamarix Species, Don L. Chadwick May 1964

Influence Of Sodium And Calcium Chlorides In The Nutrient Solution On Secretions Of Salt Glands Of Tamarix Species, Don L. Chadwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt glands are an adaptation for living in saline habitats possessed by several species of plants. In the family of Plumbaginaceae at least three mangrove genera, Aegialitis, Aegiceras, and Avicennia, possess salt glands according to Scholander (1962). Salt glands of the small ornamental shrubs, Statice gmelini, and Limonium latifoluim of the same family, were studied by Ruhland (1915) and Arisz (1955). Spartina townsendii of the Graminaceae and Tamarix petandra, Tamarix hispida, and Tamarix aphylla of the Tamaricaceae families also have the glands.

The Control Of Bitter Pit In Apples, Frank Melville, S. E. Hardisty, N. S. Shorter Jan 1964

The Control Of Bitter Pit In Apples, Frank Melville, S. E. Hardisty, N. S. Shorter

Journal of the Department of Agriculture, Western Australia, Series 4

Bitter pit is a physiological disorder of apples which causes considerable wastage of otherwise sound fruit .

It is a problem of world-wide occurrence and in Western Australia growing conditions appear particularly favourable for its development.

In recent years a practical means of control by calcium sprays has been developed.


Modern Methods Boost Apple Production In A South-West Orchard, N H. Shorter Jan 1964

Modern Methods Boost Apple Production In A South-West Orchard, N H. Shorter

Journal of the Department of Agriculture, Western Australia, Series 4

A WELL-KNOWN South-West apple orchard with an impressive cropping record is owned by W. F. & E. M. Dilley and Sons, of Upper Capel, near Donnybrook.

Trees in this orchard have been producing consistently heavy crops for many years and, furthermore, yields have increased steadily over a 10-year period.


Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates Oct 1963

Mites On Kangaroo Rats At The Nevada Test Site, Morris A. Goates

Brigham Young University Science Bulletin, Biological Series

A systematic study of parasitic mites on kangaroo rats of two species at the Nevada Test Site was conducted from August 1959 to December 1961. The intent was to determine the kinds, numbers, seasonal occurrences and ecological relationships of mites in nuclear disturbed and contiguous undisturbed areas. A total of 1,256 rats from nine plant communities was examined.

The 6,208 mites collected represented 16 species including four undescribed. Fourteen were found on both kinds of rats. Considerably more rats were infested with chiggers than with mesostigmatids. Each species of mite occurred alone on its host at least 20% of the …
