Polyploidy inference across time scales in the charismatic carnivorous plant genus Drosera L. (Droseraceae, Caryophyllales)
… of different types and ages, and to develop Drosera as a system for chromosome evolution. This was achieved by using chromosome evolution models to test different rates of chromosome evolution between different subgenera in Chapter 1. In Chapter 2, I inferred the parental lineages of Drosera …

The effects of size and habitat on δ N-15 of carnivorous plants (Drosera spp.)
… role of nutrient-poor habitats in carnivorous Drosera capensis and Drosera aliciae, and how that role changes under sunny and shady environmental conditions. The main purpose of the study was to evaluate Givnish's (1984) cost/benefit model used to explain the evolution of carnivory in …

The ecophysiological significance of insectivory as well as nitrogen and phosphorus availability to sundew nutrient cycling, growth, and success
… in field populations and greenhouse plantings. Drosera rotundifolia was studied in the field, and D. binata var. multifida and D. capensis were studied in long-established plantings in the greenhouse. In each case, experiments were performed by enclosing insects and/or adding phosphorus and/or …

The Function of Insect Trapping by Penstemon Digitalis and Cirsium Discolor
… plants have been shown to be carnivorous, e.g., Drosera spp. and Pinguicula spp., and in some cases they have been shown to provide defense against herbivores. In most plants, however, the function of such insect-trapping is not known. In two herbaceous plants native to central Illinois, …

Conditions Responsible For The Success Of Carnivorous Plants In Nutrient-Poor Wetlands
… address the second question, I used carnivorous drosera tracyi to experimentally test the effects of light availability and the availability of nutrients found in higher concentrations in prey versus nutrients found in higher concentrations in post-fire ash on relative investment in carnivory …
