Annotated Checklist Of The Vascular Plants Of Washington County, Utah, Susan Elizabeth Meyer
Annotated Checklist Of The Vascular Plants Of Washington County, Utah, Susan Elizabeth Meyer
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis is comprised of two parts, the annotated checklist of plants and the explanatory text which precedes it.
The checklist includes entries for the 1,207 vascular plant species known to occur in Washington county. each entry consists of species name, floristic component classification, community type occurrence, range termination information, specimen citations, and in some cases notes and relevant synonymy.
The explanatory text includes a discussion of the methods used in the preparation of the checklist, a description of the study area, a conspectus of botanical research in the area, and a summary of the systematic and phytogeographic affiliations of …
Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
Feeding Behavior Of Pen Reared Mule Deer Under Winter Range Conditions, Michael A. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the feeding responses of mule deer to a system of spring livestock grazing. The specific purposes were 1) to determine botanical composition of diets selected by mule deer on a winter range subjected to previous spring grazing by sheep compared to one with no sheep grazing and 2) to develop a basis for predicting selection of individual plants by deer, based on physical characteristics of the plants and the species and physical proximity of associated plants.
The study was conducted within the framework of a completely randomized experimental design with two treatments. Variables controlled for each unit …
Vegetational Response To Three Environmental Gradients In A Salt Playa Near Goshen, Utah County, Utah, Michael Grant Skougard
Vegetational Response To Three Environmental Gradients In A Salt Playa Near Goshen, Utah County, Utah, Michael Grant Skougard
Theses and Dissertations
The plant communities and individual plant species in and around a salt playa near Goshen, Utah County, Utah were studied in relation to three environmental gradients. Forty-eight stands were sampled by means of meter square gradients. Frequency data for all participating plant species were taken. Soil samples were collected from each site and analyzed to establish the environmental gradients (i.e., total soluble salts, soil moisture and hydrogen ion concentration. Results indicate that community vegetation types respond differentially to the three gradients and can be segregated on the basis of one or more of the gradients. The total soluble salts gradient …
Correlations Between Plant Species Diversity And Flower Characteristics In The Wasatch Mountains Of Utah And Idaho, William Kent Ostler
Correlations Between Plant Species Diversity And Flower Characteristics In The Wasatch Mountains Of Utah And Idaho, William Kent Ostler
Theses and Dissertations
An analysis of the relative abundance of the prevalent species in 25 major plant communities of the Wasatch Mountains demonstrates that variation in species diversity is significantly correlated with many floral characteristics. Wind pollinated flowers decrease in abundance while animal pollinated flowers increase along the diversity gradient. Both relationships are highly significant statistically. Color diversity and species diversity are significantly and positively correlated in open communities but are not correlated in forest communities. The percent sum frequency of yellow and pink-magenta flowers decreased with increasing species diversity while blue and whitish flowers increased. Also, zygomorphic flowers and flowers in which …
