Floral traits and pollination of Solidago altissima: mechanisms of local adaptation among and within biomes
Solidago altissima is an herbaceous, clonal plant that has differentiated into two subspecies in the prairie and forest biomes in Minnesota. The mechanisms that have driven the divergent evolution of these subspecies are not well understood. The evolution of floral traits is influenced by the …

Intraspecific plant polyploidy effects on goldenrod insect herbivores
… of genetic variability within a plant species, Solidago altissima L. (Asteraceae) and how this variation influences its herbivore community. More specifically, this thesis quantifies the spatial scale at which ploidy variation exists within and among population geographic distributions of …

A Geographic Mosaic of Speciation in Eurosta solidaginis
… is a fly that induces galls on tall goldenrod (Solidago altissima; Compositae) in North America with populations in the forest and prairie biomes of Minnesota, which are under divergent ecologically-based selection pressures. Previous research indicates that the goldenrod, the gallfly, and the …

Mechanisms Promoting Spatial and Temporal Variability in Plant Defense
… value of resistance and tolerance of goldenrod (Solidago altissima). Within replicate early- and late-successional fields, I quantified the spatial structure of herbivore damage and goldenrod resistance, tolerance, and fitness traits, and assessed whether the spatial structure of defense was …
