Our December topic is:  Interactions between Invasive Scotch Broom and Insects along an Elevation Gradient

Scotch broom is an invasive plant species in the Pacific Northwest. Although useful in erosion control and producing beautiful blooms each year, Scotch broom reduces natural biodiversity and timber crop yields. Past research has suggested that broom may be limited by the availability of pollinators and the effectiveness of introduced biological controls. However, such plant-insect interactions have not been evaluated in the mountains where Scotch broom competes with timber crops. Other researchers have also shown that broom evolves to optimize its interaction with pollinators along an elevation gradient. In a series of summer studies, we investigated the interactions between Scotch broom and insects. We found that, despite previous research showing the converse, broom is highly visited by pollinators. We categorized and compared pollinators at several sites along an elevation gradient, and found how flower size varies with elevation and season. The effectiveness of biological controls was also investigated, with implications for their future spread.
 

About the Speaker:

 

Robert Bode got his B.S. in Biology from Hope College in western Michigan and his PhD from Cornell University in Ithaca, New York. His past work has focused on plant-herbivore interactions and the evolution of plant defenses. However, more recently he has focused on the interactions between weedy plants and seed-eating insects. Robert has been an assistant professor at Saint Martin's University since 2014, and currently lives in Olympia with his wife and kids.


About Olympia Science Café:


Science Cafe of Olympia meets each month on the second Tuesday.  It provides an informal atmosphere where people with and without scientific background can meet to deepen their understanding on interesting topics in science and technology.  After a presentation by an expert in the field, the meetings are opened for discussion.  Science Cafes are found nationwide and are loosely affiliated with the U.K.- based Cafe Scientifique, an international organization promoting public engagement with science.

Some of the organizers of the Science Cafe of Olympia are affiliated with the Puget Sound Chapter of the American Chemical Society.
