Field guide to insect visitors of Echinacea angustifolia

Steph wrote a field guide years ago to help us identify insects that visit Echinacea heads during the summer in Minnesota. It still serves us remarkably well, but hasn’t been posted until now. Here it is!

Sarah’s presentation

Sarah Baker presented “Flowering phenology of Echinacea angustifolia in Minnesota tallgrass prairie remnants over three years,” the results of her summer 2013 REU project, at the National Conference on Undergraduate Research, University of Kentucky, on 4 April 2014.

Echinacea Project featured on TV show

Check out this episode of Prairie Yard & Garden. Stuart was interviewed this summer for this half-hour long public TV show about the Echinacea Project. The episode is called “Prairie Flora: History and Future” and it aired yesterday in western MN and the Dakotas.

Please help spread the word about prairies! Here’s the link: http://goo.gl/qU4bcN

The whole interview and much of the footage is from the main common garden experimental plot.

new x-ray images

We took some high-quality images of Echinacea achenes for our q2 experiment this fall; an example is below. Notice how easy it is to distinguish empty achenes from those with embryos. By darkening the room and removing the opaque film, we were able to use lower levels of xrays for a shorter duration than we have previously. This plate was exposed to 12kV x-rays for 4s. We used long, thin glassine envelopes to facilitate counting. Notice also that the laser-printed labels reveal the packet IDs.

Preparing site for new experiment

We are preparing to plant a new experiment this fall. We are cutting down ash trees (Fraxinus pennsylvanicus) in an abandoned agricultural field that was planted with Brome in the 1980s. We will plant Echinacea angustifolia seeds from our experimental crosses this summer. We will hand broadcast two native warm-season grasses: Bouteloua curtipendula (sideoats grama) and Schizachyrium scoparium (little bluestem). Keep up-to-date on progress on this experiment via twitter.
