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 …
