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

A Revision Of Cryptantha Subgenus Oreocarya, Larry C. Higgins
A Revision Of Cryptantha Subgenus Oreocarya, Larry C. Higgins
Brigham Young University Science Bulletin, Biological Series
This study is a taxonomic revision of Cryptantha subgenus Oreocarya (Boraginaceae), together with descriptions of species, synonyms, distribution maps, and discussions. The present treatment recognizes fifty-seven species and fourteen varieties, all separated by means of a comprehensive key, A history of the group, along with a discussion of distribution, ecology, and phylogeny is presented. As a basis for the comparison of taxa much of the research has been concentrated on morphological variation in herbarium specimens. Particular attention has been directed to a study of pubescence types, branching patterns, flowers, calyces, and fruit. The herbarium research has been correlated with extensive …

Poison Plants Of Western Australia : The Toxic Species Of The Genera Gastrolobium And Oxylobium : Thick-Leaf Poison (Gastrolobium Crassifolium Benth.), Narrow-Leaf Poison (Gastrolobium Stenophyllum Turcz.), Mallet Poison (Gastrolobium Densifolium C.A. Gardn.), Wall-Flower Poison (Gastrolobium Grandifolorum F. Muell), T E H Aplin
Journal of the Department of Agriculture, Western Australia, Series 4
THIS article deals with three species of Gastrolobium which are found in the south-west region of Western Australia. Two of these extend into the Eyre District, the third species is found in the Lake Grace area. The fourth species, Wall-flower poison, is the only toxic species of the genus found outside the State.
Vegetation And Soils Of The Balsam Fir Habitat Type Of Southern St. Louis County, Andrew F. Robinson Jr.
Vegetation And Soils Of The Balsam Fir Habitat Type Of Southern St. Louis County, Andrew F. Robinson Jr.
Journal of the Minnesota Academy of Science
ABSTRACT - The vegetation and soils of the Abies balsamea/Lonicera canadensis/Cornus canadensis habitat type were characterized from field reconnaissance, soils and plant tissue analysis of six balsam fir stands of Northeastern Minnesota. From nutrient analysis, the concentration of phosphorous and potassium was found to be much higher in living balsam fir needles than in surrounding soils.

The Vessel Member Of Myrica Esculenta Buch.-Ham., Lucy B. Abbe, Ernst C. Abbe
Journal of the Minnesota Academy of Science
ABSTRACT- The vessel members of Myrica escu/enta from two_ trees, one in Sarawak, the other in Singapore, are described. The differences in habitat as well as in vertical position in each-tree have a minor influence on dimensional characteristics of the vessel members. However, radial position is very significant. Average length of element increases from 600μ, to 950μ, b~tween .05 cm from the pith to 1.75 cm from the pith and then ceases to elongate appreciably. Average diameter over the same radial distance increases from 30μ, to l 05μ. Also over the same radial distance, the average number of perforations of …
Land Use In Wah Wah And Pine Valleys, Western Utah, Joseph R. Murdock, Stanley L. Welsh
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
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 …

Fisheries Report No Viii (8) - Report On A Visit Of Inspection To Barrow Island November 1969, A. A. Burbidge, A. R. Main
Fisheries Research Reports
The aim of the inspection was to examine the effects on the fauna and flora of the oil exploration initiated in mid-1963 by West Australian Petroleum Pty. Ltd. (WAPET) and the construction and development programme which followed in 1966 and which is now nearing completion.
