Fisheries Report No 9 - The Fauna And Flora Of Monte Bello Islands, A. A. Burbidge Dr Jan 1971

Fisheries Report No 9 - The Fauna And Flora Of Monte Bello Islands, A. A. Burbidge Dr

Fisheries Research Reports

Two visits were made to the Monte Bello Islands in 1970 and 1971.

The aim of the visits was to examine the islands for the presence of native mammals and other fauna, and to explore the possibility of re-establishing fauna now extinct,

The first survey was carried out in conjunction with a more detailed examination of the Dampier Archipelago. The fisheries patrols vessel "Dampier" was used to reach the islands and as a base. Personnel were R. Johnstone (W.A. Museum), E.J. Little and J.D. Harman (crew of the "Dampier"), R.F. Dear and A.A, Burbidge, all from the Department of Fisheries …


Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr Jan 1971

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …

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 Dec 1970

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 Oct 1970

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 …

Distribution Of The Native Trees Of Utah, Kimball S. Erdman Sep 1970

Distribution Of The Native Trees Of Utah, Kimball S. Erdman

Brigham Young University Science Bulletin, Biological Series

Although botanists have been actively collecting in Utah for well over a century, the distribution of many plants are as yet imperfectly known. This is, in part, due to the scattered nature of Utah herbarium material. Also the terrain of the state has impeded collection in more rugged and remote areas. The present study gathers together the data from the major collections of native Utah trees and clarifies our present understanding of tree distributions in the state. The older collection records have been extensively supplemented by the field work of the author and other botanists.

The great diversity of environments …

Osteological And Mylogical Comparisons Of The Head And Thorax Regions Of Cnemidophorus Tigris Septentrionalis Burger And Ameiva Undulata Parva Barbour And Nobel (Family Teiidae), Don Lowell Fisher, Wilmer W. Tanner Jun 1970

Osteological And Mylogical Comparisons Of The Head And Thorax Regions Of Cnemidophorus Tigris Septentrionalis Burger And Ameiva Undulata Parva Barbour And Nobel (Family Teiidae), Don Lowell Fisher, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The anterior osteological elements of the skull, lower jaw, and wrist along with the anterior myological characters discussed and figured in this report suggest that A. u. parva and C. t. septentrionalis are members of distinct groups which can be differentiated by internal morphologic characters. Although comparisons were restricted to highly geographically separated individuals of the same family, their general body form and structure appear to be similar.

A great number of anatomical structures are shared in common, but the significant differences between them include:

1. General skull appearance. The skull of C. is generally lighter, that is the bones …


Pinyon-Juniper Succession After Natural Fires On Residual Soils Of Mesa Verde, Colorado, James A. Erdman Jun 1970

Pinyon-Juniper Succession After Natural Fires On Residual Soils Of Mesa Verde, Colorado, James A. Erdman

Brigham Young University Science Bulletin, Biological Series

A mountain brush vegetation typified by Gambel oak (Quercus gambelii) and serviceberry (Amelanchier utahensis) dominates the uplands of Mesa Verde National Park. There is evidence that this brush element is a successional stage that has been maintained by repeated natural fires in a large part of the Mesa Verde landscape. This study was conducted to determine the role of fire in the region's ecology, the nature of the climax pinyon pine (Pinus edulis) and Utah juniper (Juniperus osteosperma) vegetation, and the major successional stages that lead to the climax condition.
