More Butterfat Per Acre At Denmark Research Station, Department Of Agriculture, Western Australia

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

STOCKING rates on dairy farms are generally too low and can be substantially increased, but unfortunately there is no satisfactory measurement to indicate the potential of a particular pasture or environment.

A trial carried out on Denmark Research Station in 1966-67, to obtain information on carrying capacity of a dryland kikuyu-subterranean clover pasture.

Some Observations On Maccoa Duck Behaviour, Paul A. Johnsgard

Paul Johnsgard Collection

The recent comprehensive review of Maccoa Duck Oxyura maccoa biology by Clark (1964) has provlded the first detailed summary of the species' reproductive behaviour patterns and other aspects of breeding in this little-studied stiff-tail. It has been evident that the evolutionary relationships of the Maccoa Duck to the other southern hemisphere stiff-tails and the northern species of Oxyura are still uncertain at best, as evidenced by the varied taxonomic treatment that the Maccoa has received from Delacour and Mayr (1945), who regarded it as a race of O. australis, from Boetticher (1952), who consldered it as a race of O. …

Overwintering Sites And Winter Mortality Rates Of Certain Predaceous Mites In Central Utah Orchards (Phytoseiidae: Typhlodromus), John Wayne Leetham

Theses and Dissertations

The overwintering habitats and winter mortality rates of predaceous mites (Phytoseiidae: Typhlodromus) were investigated during three successive winters, 1965-66, 1966-67, and 1967-68. Three species were predominant in derelict apple orchards, Typhlodromus mcgregori Chant on twigs and spurs and rough bark of scaffold limbs and trunk, Typhlodromus occidentalis Nesbitt on rough bark of scaffold limbs and trunk, and Amblyseius cucumeris Oudemans in ground cover. Other species (Typhlodromus columbiensis Chant, Typhlodromus caudiglans Schuster, Amblyseius fallacis (Garman), Amblyseius ovatus (Garman), Amblyseius floridanus (Muma), and Amblyseius rosellus Chant) were collected only incidentally. Substantial numbers of T. mcgregori and T. occidentalis were found to fall …

Nesting Ecology Of The Ferruginous Hawk (Buteo Regalis) In West-Central Utah, John Bradford Weston

Theses and Dissertations

During the spring seasons of 1967 and 1968 ecological studies were made of nesting Ferruginou.s Hawks (Buteo regalis) in a 325 square mile area in west-central Utah. In the springs of 1967 and 1968 a systematic search was conducted throughout the study area for Ferruginous Hawk nests. When active nests were located they were kept under observation throughout the study. The density of nesting pairs in 1967 and 1968 ranged from 7 to 15.4 square miles per pair. An annual seasonal displacement was exhibited, with Ferruginous Hawks being present in the study area only during the nesting season, which lasted …

A Study Of The Channel Catfish, Ictalurus Punctatus (Rafinesque), In Mud Lake, Utah, Horst Friedrich Siewert

Theses and Dissertations

From June to November 1967, a study on channel catfish, lctalurus punctatus (Rafinesque), in Mud Lake, Utah Co., Utah was undertaken. The objectives were (I) to estimate if channel catfish are increasing or decreasing in Mud Lake, (2) to estimate the mean size of adult channel catfish in Mud lake, (3) to determine which environmental factors effect the catch of channel catfish, and (4) to determine if the channel catfish in Mud lake are residents year round. A total of 310 mature channel catfish and 920 carp were collected with four hoop nets. Two fingerling were captured by seining. Ratios …

An Investigation Of A Thyroidal Control Of Water Balance In The Leopard Frog, Rana Pipiens, Scott Mcclung Martin

Theses and Dissertations

A possible thyroidal control of water balance in the leopard frog, Rana pipiens, was investigated by (1) chemically thyroidectomizing intact animals by chronic injections of the goitrogen, 6-n-propyl-2-thiouracil (PTU ), or making animals hyperthyroid with thyroxine injections, and (2) dehydration of the frogs in a flow of air to enhance the rate of water loss through the skin, followed by rehydration in tap water until the animals regained their former weight. Radioiodine was employed in limited studies on the frog thyroid gland to ascertain the effects on thyroidal function caused by PTU. The frogs were dehydrated in desiccators in which …

Niche Differentiating Mechanisms In Two Sympatric Species Of Swallows, David Thomas Moody

All Master's Theses

The present study considers certain aspects of the ecologies of cliff swallows (Petrochelidon pyrrhonota) and bam swallows (Hirundo rustica) in an area of overlap, where both species are found nesting together and foraging over the same fields. Careful attention was given to foraging flight patterns, foraging elevations, and food consumed by each species in an effort to determine whether or not there is any evidence of competition for food resources. Aggressive interactions between the species were recorded, and the general timing of their nesting cycles was noted.

Osteology And Myology Of Phrynosoma P. Platyrhinos Girard And Phrynosoma D. Hernandesi Girard, Richard L. Jenkins, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

This study confirms the work of Etheridge (1964) in suggesting the peculiarity of the genus Phrynosoma within the family Iguanidae. The anterior osteology and myology of Phrynosoma platyrhinos platyrhinos Girard and Phrynosoma douglassi hernandesi Girard indicate Phrynosoma to be highly specialized and to differ significantlv from the Iguanid structure as portrayed by Oelrich (1956), Robison and Tanner (1962), and Avery and Tanner (1964). They also differ because of: ( 1 ) absence of lacrimal and postfrontal bones; (2) occurrence of occipital (also mandibular and temporal) spines; (3) posterodorsal shift of the skull elements; (4) divided nature of the M. sternohyoideus, …

Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.

Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10^-4 μg ± 6.6 x 10^-4 μg.

Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.

After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …

Ticks Of The National Reactor Testing Station, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

During the period from June, 1966, to September, 1967, 27 amphibians of two species, 446 reptiles of eight species, 561 birds of 81 species, and 4050 mammals of 26 species were examined for ectoparasites at the National Reactor Testing Station in southern Idaho. Of seven species of ticks collected, the predominant one was Ixodes kingi, found on mammals of 12 species. Next in abundance was Dermacentor andersoni found on birds of three species and mammals of 16 species. Haemaphysalis leporispalustris was taken from birds of 10 species and six spvecies of mammals. Four other species of Ixodes were taken from …

Dispersal Of Mites Within Apple Trees Of An Abandoned Orchard In Central Utah, Eugene Eldon Nelson

Theses and Dissertations

From January to July, 1967, a study of dispersion and distribution characteristics of Typhlodromus mcgregori Chant, Bryobia praetiosa Koch, and Bryobia rubrioculus (Scheuten) was made in an abandoned apple orchard in Highland, American Fork, Utah and in the laboratory at Provo, Utah. Bryobia praetiosa overwintered on the spurs and the other protected sites and with the advent of spring migrated out of the tree and back onto the cover crop. Coinciding with the movement of B. praetiosa out of the tree was the hatching of winter eggs and maturation of B. rubrioculus primarily on the spurs but as far down …
