A Taxonomic Study Of Crotaphytus Collaris Between The Rio Grande And Colorado Rivers, William Ingram Iii, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

Little work has been done previously on the taxonomy of Crotaphytus collaris baileyi. This and the demonstration by Fitch and Tanner that C. c. baileyi is a heterogeneous grouping prompted the present study. Only the populations of the type material, the Upper Colorado River Basin, and the Chihuahuan Desert were studied. Multivariate, variance, canonical and discriminant analyses of external characters were performed, and pattern-coloration characters were examined on living specimens.

The results of the analyses show significance between all three populations. The discriminant functions distinguished between the populations with 80% reliability and patternal characters were discriminatory with near 100% reliability. …

Basic Pig Breeding, P Mcnamara

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

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.

Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh

Brigham Young University Science Bulletin, Biological Series

This is a review of the use of public lands in Wah Wah and Pine Valleys in western Utah for grazing of livestock, mining, and other private enterprises. The total area of the two valleys is approximately 1,440 square miles of which about 30 square miles are privately owned. From the time grazing of domestic livestock was initiated in the 1870's and 1880's until 1934, the land was free public domain and was grazed on a first-come, first-served basis. Passage of the Taylor Grazing Act in 1934 ended free use of public lands. Existing evidence indicates that by 1934 the …

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The problem of phylogenic relationships within the iguanine phyletic line and the Madagascar iguanids have been investigated in order to explain the discontinuous distribution exhibited by the members of the family Iguanidae. Owing to inconclusive results from cytology and histological methods, the comparative morphology of the anterior osteology, myology, tongues, and hemipenes were used to determine relationships.

An examination of the above structures of the members of the iguanine phyletic lines and a comparison with the Madagascar iguanids indicates the following: ( 1 ) The Madagascar genera Chalarodon and Oplurus appear to be more closely related to each other than …

Pasture Legume Varieties And Ewe Fertility, T Marshall, H. E. Fels, H. G. Neil, R. C. Rossiter

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

ALTHOUGH it was first thought that all varieties of subterranean clover would cause ewe infertility, research in the last 10 to 15 years has shown that varieties differ in potency.

The relative level of potency has also been shown to remain consistent for any one variety under normal conditions.

Rural Radio Reports - Animals And Birds Declared Vermin, A R. Tomlinson

Mycotic Dermatitis (Lumpy Wool) Of Sheep, M R. Gardiner

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

MYCOTIC dermatitis is a common disease of the skin and overlying wool of sheep (and other herbivorous animals).

The photographs show the typical crusts and scabs which result from infection of skin, hair and wool follicles by the mycotic dematitis organism.

This article reviews the causes of lumpy wool infection and sets out control measures.

Mulesing : Still The Best Weapon Against Fly-Strike, R A. Mills

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

Infectious Sinusitis Of Turkeys, J Edgar

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

Climatic conditions in W.A. are ideal for turkey production if advantage is taken of the wide open spaces. Over-crowded, poorly ventilated quarters are ideal for the spread of infectious sinusitis, and the disease, once established, is hard to eliminate without a complete change of birds.

This article provides advice for the prevention of this important disease at a time when turkey raising is increasing in W.A.

Wildlife Hazards From 1080 Baiting, A R. Tomlinson, C. D. Gooding

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

ONE-SHOT oat baiting with sodium fluoroacetate (1080) is a relatively safe method of trail baiting rabbits.

The hazard to wildlife is small and every effort is made to further reduce the hazard by selective application of the poison.

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The differences observed from the osteology and myology are few and subtle.

Neither species is consistent in having all of the anatomical characters equal. E. skiltonianus, however, is more variable than gilberti. This species: 1. exhibits a wider range of variation in the number of slips of the intermandibularis anterior; 2. has two distinct bundles of the depressor mandibularis; and 3. has variation in the anterior suture pattern of the frontal, nasal, prefrontal and maxilla elements. E. gilberti on the other hand has: 1. only one distinct bundle of the depressor mandibularis; 2. a frequent reduction of the relative size …

Mites And Lice Of The National Reactor Testing Station, Dorald M. Allred

Brigham Young University Science Bulletin, Biological Series

Mites of 47 species and lice of 16 species were taken from reptiles of 3 species, birds of 23 species, and mammals of 18 species at the National Reactor Testing Station between June, 1966, and September, 1967. Mammals differed in degree of infestation relative to their geographic distribution at the station. The number of species of ectoparasites which occurred on a particular kind of host generally was in direct proportion to the number of hosts examined, but exceptions occurred in some instances. In some cases the rate of infestation differed relative to the sex of the host. The greatest numbers …
