Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie

Fisheries Research Reports

The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.

The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Light And Electron Microscopy Investigation Of Developing Wheat Caryopses Infected By Tilletia, Melvin Douglas Grove

Theses and Dissertations

Caryopses of wheat were studied during infection by Tilletia caries and T. controversa. Initially the pathogens penetrated embryos of the host. After the embryo tissue was consumed by the fungi, endosperm tissue was penetrated and consumed. Initial penetration of endosperm tissue was in localized areas. During infection the fungus mycelium spread intercellularly, but occasionally was seen intracellularly. As the host tissue was consumed teliospores were formed. At maturity a host cell layer 4-6 cells thick remained which retained the mature teliospores. Histochemical studies indicated that carbohydrates and lipids of the host disappeared soon after invasion by the pathogens. Nuclei and …

Community Characteristics Of Six Burned Aspen-Conifer Sites And Their Related Animal Use /|Clarry H. Kleinman, Larry H. Kleinman

Theses and Dissertations

Six forest areas destroyed by fire representing different seral stages of aspen development and conifer invasion were studied to determine successional dynamics and the related livestock and big game use. Factors measured were: (a) age, basal area, density and frequency of aspen and conifer trees; (b) density and frequency of under-story species; (c) forage production for forbs, grasses, and browse, and (d) animal-days use for deer, cattle and sheep. Aspen appeared in the community the spring following the fire and conifers appeared fifteen to twenty years later. Conifers had begun to dominate aspen on an eighty-two year old stand. The …

Community Structure And Production In A Marsh On The Southern Branch Of The Elizabeth River, Virginia, Michael Bassett Robblee

Biological Sciences Theses & Dissertations

Four different plant communities occur on the Southern Branch of the Elizabeth River, Virginia, 1. Spartina alterniflora, 2. Distichlis spicata - Spartina patens - Juncus roemerianus, J. Baccharis halimifolia - Iva frutescens and 4. Spartina cynosuroides. The cordgrasses s. alterniflora and S. cynosuroides dominate the marsh.

Based-on standing crop estimates S. alterniflora produced 1218.6 grams dry wt/m² and S.cynosuroides 1681.3 grams dry wt/m², which is much higher than generally assumed for Virginia marshes. Evidence for the presence of two crops of S. alterniflora on the marsh during the growing season is-presented.

Two animal associations, composed …

*The first 11 pages are adapted from J.B. Bardsley's "How to make more profit on dairy farms".

This book is designed to show you how to draw up partial budgets.

If you are like most farmers you are probably searching for different ways of running your farm to increase farm income. Choices between alternatives are very difficult, and require a great deal of careful thought and planning, especially where large cash outlays are involved. But to decide how, where and what to produce with any confidence you need to consider all the physical …

Choices between alternatives are very difficult, and require a great deal of careful thought and planning, especially where large cash outlays are involved.

Effects Of A Nuclear Detonation On Arthropods At The Nevada Test Site, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

Fifty-three arthropod species were studied in an area affected by an underground nuclear detonation. These were represented by 10 species of ants, 17 beetles, 5 orthopterans, 4 scorpions, 6 solpugids, and 11 spiders (Table 16). Relative populations were determined prior to the detonation and at three periods after the detonation–(1) one and two months after (August and September 1962), (2) 11 months after (June 1963), and (3) 13 months after (August 1963). One and two months after the detonation, the number of species was reduced from the expected by 48 percent, by 52 percent after 11 months, and by 66 …

An Ecological Survey Of The Algae Of Huntington Canyon, Utah, Lorin E. Squires, Samuel R. Rushforth, Carol J. Endsley

Brigham Young University Science Bulletin, Biological Series

A quantitative and ecological study of the algae of Huntington Canyon, Emery County, Utah, was conducted from March 1971 to April 1972. Net plankton, nannoplankton, periphyton, and visible attached algae were studied. Certain physical and chemical parameters in the waters of Huntington Creek and a small pond along its course were also measured.

Huntington Creek contains a wide diversity of genera and species of algae. Diatoms are the main constituent of the flora of this stream throughout the year. Hydrurus foetidus is prevalent in Huntington Creek from late winter to early summer, and filamentous blue green algae abound in the …

The Peregrine Falcon In Utah, Emphasizing Ecology And Competition With The Prairie Falcon, Richard D. Porter, Clayton M. White

Brigham Young University Science Bulletin, Biological Series

This study was undertaken to record the known history of the Peregrine Falcon (Falco peregrinus) in Utah as we have been able to construct it from both the literature and from our original research that extends over about a 30-year period in the state. The present total population of the peregrine in Utah is possibly only 10 percent of what it has been in historic times. In an effort to find explanations for the decline, we have explored hypotheses of climatic changes, impact of pesticides, disease, and human disturbances. We conclude that pesticide contamination and climatic changes may …

Breeding Ecology Of Raptors In The Eastern Great Basin Of Utah, Dwight G. Smith, Joseph R. Murphy

Brigham Young University Science Bulletin, Biological Series

A comparative study of the breeding ecology of 12 raptor species was conducted in the eastern Great Basin from 1967-1970. The project was designed to determine the composition and densities, habitat selection, territoriality and predatory habits of raptorial birds in a semiarid environment. All topics were analyzed comparatively, relating the requirements and activities of the 12 raptor species.

Average yearly population densities of all species approximated 0.5 pairs per square mile, but much of the available habitat was not utilized. Predominant raptors were the Ferruginous Hawk and Great Horned Owl. Other important raptors included the Golden Eagle, Red-tailed Hawk and …

Bacteriophage Φ6: A Lipid-Containing Virus Of Pseudomonas Phaseolicola, Anne K. Vidaver, R. K. Koski, James L. Van Etten

Department of Plant Pathology: Faculty Publications

The purification and properties of a lipid-containing bacteriophage, φ 6, are described. The phage contains a lipid envelope which is probably essential for infection. Infectivity of φ 6 was lost in the presence of organic solvents, sodium deoxycholate, and phospholipase A. The fatty acid composition of the phage lipid was similar to that of the Pseudomonas phaseolicola host cells. The phage was composed of about 25% lipid, 13% RNA, and 62% protein. The buoyant density of φ6 was 1.27 g/ml in cesium chloride. The morphology of φ6 was unusual; it had a polyhedral head of about 60 nm surrounded by …

Formation And Control Of Chlorophyll, Solanine Alkaloids, And Sprouts Of Potato (Solanum Tuberosum L.) Tubers And Carbonyl Compound Of Tomato (Lycopersicon Esculentum Mill.) Fruits, S. J. Jadhav

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Part I. Formation and control of chlorophyll, solanine alkaloids, and sprouts of potato (Solanum tuberosum L.) tubers

Incorporation of radioactive carbon from acetic acid-2-¹⁴C (sodium salt), β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C, L-leucine-U-¹⁴C, L-alanine-U-¹⁴C, and D-glucose-U-¹⁴C into the predominant glycosidic steroidal alkaloids, ⍺-solanine and ⍺-chaconine of potato sprouts was 4.88, 9.0, 15, 24, and 20 times less than that of mevalonic acid (MVA)=2-¹⁴C (DBED salt), respectively. The efficiency ratio revealed that β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C was incorporated via acetate or acetoacetate. The distribution of radioactivity originated from D-glucose-U-^{14 …}
