| Research Project Title: | The chemical ecology of Delphinium, Lupinus, and Veratrum. |
| Investigator: | Daniel Cook |
| Abstract:: | The genera Delphinium, Lupinus, and Veratrum are potentially toxic and/or teratogenic to herbivores on rangelands. The bio-active compounds responsible for the toxic and/or teratogenic potential of these genera represent different types of alkaloids and are well characterized chemically. Our general research interests relate to the chemical ecology of these bioactive compounds. The proposed research will survey the nectar and pollen of select species within these genera for the presence of these alkaloids. If the pollen and/or nectar are found to contain these compounds, follow-up studies will be pursued in the future to determine if there is any adaptive advantage to having these alkaloids in the pollen and/or nectar. In addition, we plan to determine if experimental manipulations of temperature results in changes to the qualitative and/or quantitative composition of the toxic alkaloids in Delphinium nuttallianum. |
