A Population Study Of Three Iris (Iridaceae) Species Native To The Siskiyou Mountains In Southwestern Oregon And Adjacent California, Carol Anne Wilson
A Population Study Of Three Iris (Iridaceae) Species Native To The Siskiyou Mountains In Southwestern Oregon And Adjacent California, Carol Anne Wilson
Dissertations and Theses
The series Californicae is a natural grouping of Iris species native to Oregon, Washington and California. Natural and experimental hybridization is characteristic of the series which has led to confusing taxonomies for some species. Populations of species belonging to this series and found on the northwestern slopes of the Siskiyou Mountains cf southwestern Oregon and adjacent California were investigated. Methods used were numerical classification techniques for morphological characters including both discriminant and K-means cluster analyses and a chemotaxonomi c analysis of flavonoid pigments using thin layer chromatography.

Vegetation Analysis Of Three Zones Of Belmont Prairie, Dupage County, Illinois, Susan Eckert Ruta
Vegetation Analysis Of Three Zones Of Belmont Prairie, Dupage County, Illinois, Susan Eckert Ruta
Masters Theses
Belmont Prairie is located in Downers Grove, DuPage County, Illinois, and is one of the few preserves of a native tall grass prairie. It is located in the Morainal section of the Northeastern Morainal Division, and harbors over 100 species of native prairie plants which are typical of the community type. Three vegetation zones were sampled for species composition and both frequency and relative frequency. These areas are as follows: Dry mesic upland area, sedge meadow, and transitional area.
The upland dry mesic zone had diverse vegetation including forb and grass species such as Parthenium integrifolium, Silphium laciniatum, …

Morphological Variation Of The Foraminifer Elphidium Excavatum (Terquem) On Crumps Bank And Willoughby Bank, Chesapeake Bay, Virginia, Pamela Kay Painter
Morphological Variation Of The Foraminifer Elphidium Excavatum (Terquem) On Crumps Bank And Willoughby Bank, Chesapeake Bay, Virginia, Pamela Kay Painter
OES Theses and Dissertations
Six variants of the highly variable foraminiferal species, Elphidium excavatum (Terquem) were recognized in the Crumps Bank and Willoughby Bank areas of the southern Chesapeake Bay. Measurements of the size of the test, the number of chambers, the number of umbilical bosses, and the number and average length of the sutural bridges on the last formed chamber, and opaqueness or translucence of the test were made on 30 specimens from each of 36 stations selected for differences in environmental parameters. The measurements were statistically analyzed by discriminant analysis to test the hypothesis that the variants are distinct morphotypes and to …

Variation In Leaf Macronutrients Of Overstory Trees As Influenced By Species Season And Soil Type In The Great Dismal Swamp Of Virginia, Bruce J. Bandle
Variation In Leaf Macronutrients Of Overstory Trees As Influenced By Species Season And Soil Type In The Great Dismal Swamp Of Virginia, Bruce J. Bandle
Biological Sciences Theses & Dissertations
Leaf macronutrient variation was studied in four plant communities in the Dismal Swamp of Virginia. composition differed markedly between these sites. Soils and species Eight important overstory trees were studied in August 1980; whereas red maple (Acer rubrum L.} and black gum (Nyssa sylvatica Marsh.}, which occurred on all four sites, were sampled seasonally. Significant differences (p .05) were found in the nutrient concentrations of the leaves between species, seasons, and sites. These differences may be attributed to inherent species characteristics, leaf expansion, nutrient translocation, and differences in soil organic matter content, pH, and degree of …
