A Comparison Of Meteorologic Measurements From Irrigated And Non-Irrigated Plots, Provo, Ut, 1970–1972, Ferron L. Andersen, Phil D. Wright, J. Carl Fox Apr 1974

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 …


A Taxonomic Study Of The Western Collared Lizards, Crotaphytus Collaris And Crotaphytus Insularis, Nathan M. Smith, Wilmer W. Tanner Apr 1974

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, …

Taxonomy Of The Genus Chloris (Gramineae), Dennis E. Anderson Mar 1974

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 …

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg Mar 1974

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg

Department of Agronomy and Horticulture: Faculty Publications

Most reports show good agreement between evapotranspiration (ET) rates estimated by Bowen Ratio-Energy Balance (BREB) method and rates measured with lysimeters, although underestimation by the BREB model has occasionally been reported. This study was conducted to evaluate the performance of the BREB technique in the climatic conditions characteristic of the central Great Plains, a region where a significant proportion of the energy consumed by evapotranspiration is supplied from advected sensible heat.

Agreement between the BREB method and lysimetric measurements of ET is good during non-advective periods but during advective periods the BREB model underestimates ET by about 20%. Data collected …

Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith Jan 1974

Variation In Ligule Spotting In Coreopsis Basalis, Edwin B. Smith

Journal of the Arkansas Academy of Science

The ligules of Coreopsis basalis bear an attractive reddish-brown spot at the base. The spot has been used as a taxonomic character of the species. But there is variation within populations at any one time, and within individuals at sequential times, for the size of the spot. A few individuals lack the ligule spot entirely. Variation in average ligule spot size in greenhouse-grown populations of C. basalis and an artificial hybrid is described. Average spot size declines as the blooming season progresses. Some individuals with spotted ligules early in the season bore spotless ligules late in the season. No correlation …
