On Saturday, Katherine continued working with aphids--moving them about in the common garden. I (Karen) continued working on my style persistence project. I am testing style persistence as a measure of pollen limitation in perennial Helianthus species through different pollination treatments. There are some promising preliminary results: for many, when treated with compatible pollen, the styles will shrivel in 1-2 days and will persist longer when treated with incompatible pollen or restricted from pollen. The following pictures show Helianthus pauciflorus after four days with incompatible and compatible pollen, respectively.

On Sunday, some of us took a trip to Glacial Lakes State Park for picnic lunch and 5mile hike. What a great outing!!!!
