Life-history and physiological trade-offs to reproduction of invasive and noninvasive Rubus

Creator:: McDowell, Susan C.
Abstract:: The goal of this dissertation was to improve our understanding of the physiology and life-history of invasive plants and of the mechanisms underlying life-history trade-offs. I compared invasive and noninvasive species of Rubus (blackberry) that grow together in the Pacific Northwest. Three hypotheses were investigated: (1) Invasive Rubus have higher...

A biosystematic study of some North American species of Agrostis L. and Podagrostis (Griseb.) Scribn. & Merr.

Creator:: Carlbom, Curt Gerald, 1932-
Abstract:: A taxonomic investigation was made of 24 taxa belonging to the section Trichodium (Michx.) Trin., of Agrostis, and the genus Podagrostis. Experimental methods were employed, including: uniform garden culture of transplants and plants grown from seeds collected in natural populations; breeding studies; physiological and phenological investigations; cytological studies; ecological studies...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

Technology and the origin of human hemispheric asymmetry

Creator:: Boraas, Alan Sivert
Abstract:: This paper proposes that human asymmetrical hemispheric function originated because of the cognitive requirements of tool-making. The human brain can be considered to be a product of two evolutionary episodes. The first episode was shared with other mammals and resulted in a brain composed of a reptilian complex, paleomammalian and...

A fistful of Astragalus : phenotypic and genotypic basis of the most taxon rich species in the North American flora

Creator:: Knaus, Brian J.
Abstract:: The study of the infra-specific ranks (i.e., subspecies and variety) can be considered the study of the process of speciation. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxon rich species in the U.S. flora currently including 40 taxonomic varieties. These varieties were described using traditional taxonomic methods primarily...

Somaclonal variation, regeneration and transformation of quince (Cydonia oblonga Mill.) and pear (Pyrus communis L.)

Creator:: Bunnag, Sumonthip
Abstract:: Quince (Cydonia oblonga Mill.) is widely used as a dwarfing rootstock for pear {Pyrus communis L.). The disadvantage of this rootstock is its inefficient uptake of Fe, resulting in leaf chlorosis. Application of tissue culture and gene transfer techniques may lead to production of quince clones with improved Fe efficiency....
