Research Project Description:
Working in Dr. Susan Mazers lab in the department of Evolution, Ecology, and Marine Biology I studied the evolution of mating systems in flowering plants. My specific work looks at pollen performance and sexual selection between outcrossing and selfing Clarkia species or sister taxa. Our hypothesis is that outcrossers will have higher pollen tube attrition rates than selfers. In other words, cross pollinators will have more pollen tube deaths than self-pollinators. Our data supports this hypothesis with almost twice the mean pollen attrition rates in the two outcrossing taxa compared to the two selfing taxa.
Our conclusion is that pollen tube attrition occurs at different rates in different species of Clarkia with different mating systems. Specifically, higher attrition rates were observed in the outcrossing species. This was a wonderful program. The knowledge and skills gained will surely improve and enrich learning for my students.

Curriculum Project Description:
Two inquiry-based units are presented: “Flower Power” and “Don’t Blow it”. These lessons are easily adapted to cover a variety of State, Common Core and Health standards. The emphasis is health –a topic which is increasingly being required in science. Both labs include community service and family involvement components.
