A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner
A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner
Brigham Young University Science Bulletin, Biological Series
The heterogeneous nature of the collared lizards west of the Colorado River prompted this study. Samples from known populations of C. c. auriceps, C. c. baileyi, and C. c. fruscus were used as a base for defining the western populations. External morphology and cranial morphology were compared by cluster, canonical, and discriminant analyses.
Results of these analyses show a western complex of four populations which are distinct from the three base populations of the collaris complex. Members within the western complex are distinguishable with at least 90 percent reliability by discriminant analysis. Because of intergradation patterns seen in western Sonora, …
A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox
A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox
Brigham Young University Science Bulletin, Biological Series
A comparative study of micrometeorologic conditions on irrigated and non-irrigated pasture plots was conducted at Provo, Utah, from 1970 to 1972. Daily measurements were taken of the following: precipitation cither as rain or snow, new snowfall and total snow depth during the winter; relative humidity in a standard weather shelter; number of hours at maximum relative humidity; cloud cover each morning; potential evaporation; total wind 1 m above ground level; temperature extremes in a standard weather shelter; and temperatures both on irrigated and non-irrigated plots with sensing devices located 5 cm beneath soil surface under grass cover, at soil surface …

Taxonomy Of The Genus Chloris (Gramineae), Dennis E. Anderson
Taxonomy Of The Genus Chloris (Gramineae), Dennis E. Anderson
Brigham Young University Science Bulletin, Biological Series
This study is a worldwide taxonomic treatment utilizing endomorphic characters such as cytology, histology, and embryology, in addition to the traditional exomorphic features. New chromosome numbers and histological information are reported. Relationships between Chloris and other genera in the Chlorideae are discussed. A total of 56 species is recognized in the genus; each is described and illustrated. Complete synonymies are included as well as a list of unidentified or rejected names. Distributions and maps are given for each species, along with lists of specimens examined during studies at various herbaria. Reports of field studies involving introgression among certain species are …
