Research Interests

For many years I have been interested in the ecological genetics of cyanogenesis in plants. This has pioneered the study of plant/herbivore interactions mediated by plant chemistry, with the bonus of showing how it is possible to use genetics to prove chemical defense by plants. It has been known for many years that some plants are cyanogenic and whole conferences have been held to discuss cyanogenics in cassava. We now know that 16 of the 24 most important food plants are cyanogenic. Field research on cyanogenic plants has highlighted the need to be able to identify, not only individual perennial forbs from year to year, but also the male parents of seeds collected from wild plants. I am interested in the ecological genetics of flower colours and consequently in the colour of flowers as perceived by bees. Techniques for measurement of temperature within flowers are being developed with Dr. T. J. Crawford, University of York, UK. I have also been continuing the long-term study of the scarlet tiger moth at Cothill Fen near Oxford in England.
