  1. Mechanisms Promoting Spatial and Temporal Variability in Plant Defense

    … and quantify their associated fitness costs and selection gradients. Lastly, I conducted a field experiment to test the prediction that successional changes in the environment alter the adaptive value of resistance and tolerance. To this end, I transplanted goldenrod genets into early- and …

  2. Process Applications of NMR

    … is modified to include flow-compensated slice selection gradients. The accuracy of the compositions measured from volume selective spectra is measured as ±1 mol% and ±2 mol% for static and flowing mixtures respectively. Pulsed field gradient NMR sequences using double echoes for flow …

  3. The Relative Roles of Herbivore- and Pollinator-mediated Selection on the Evolution of Floral Display in the Invasive Plant, Lythrum salicaria

    … some circumstances, may even impose stronger selection on floral display than pollinators. This is especially true when the traits under selection are linked to anti-herbivore defense. Here I describe a study in which I quantified the relative role of herbivores and pollinators in selection
