Hyperparasitism and Disease Ecology in Plant Communities
Mentor & Lab: Edith Lai, Parker & Gilbert Lab
Positions: 1 intern
Tentative dates: Mid June through Mid August 2025
Project Location: Coastal Biology Building for lab work and Santa Cruz County for fieldwork day trips
Project Background: How are diseases regulated in natural communities? Powdery mildew fungi are widespread pathogens affecting thousands of plant species around the world, including many of conservation and agricultural value. We are studying the ecology of a fungal hyperparasite (a parasite of parasites) that attacks powdery mildew fungi and reduces disease impacts for plants. In the Summer of 2025, we will be surveying plant communities throughout Santa Cruz County for infection to map the distribution of disease and hyperparasitism infections.
Intern duties: The intern will be conducting both field and lab work at approximately a 50/50 split. Fieldwork will consist of visiting local parks, farms, and neighborhood gardens to survey plants for powdery mildew infection and bring infected leaf samples back to the lab. Lab work will consist of microscopy, fungal culturing, and molecular work (DNA extractions + PCR). In addition, the intern will be involved in data management and data analysis.
Intern qualifications:
Comfortable with moderate amounts of physical activity in the field
Would prefer the intern to have their own method of transportation, but not a strict requirement
Strong attention to detail and willingness to learn new things
Do you recommend the intern(s) volunteer in your lab during Spring quarter?
Yes, we recommend starting in Spring quarter
