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!

Several web pages that provide helpful advice about http://tos.org/resources/publications/sci_speaking.html Specific for poster presentations: Steve Ellis recommended some readings for us. Here they are: http://libcloud.s3.amazonaws.com/93/3a/3/4738/GardenersBewareReport_2014.pdf http://www.pnas.org/content/early/2013/10/18/1314923110.full.pdf+html http://www.gmfreecymru.org/pivotal_papers/JEIT-D-12-00001_proofs.pdf http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0103592 http://modernfarmer.com/2013/05/can-a-lawsuit-save-americas-bees/ Also, here are two mainstream media pieces on the topic of honeybees and pesticides: http://video.msnbc.msn.com/nightly-news/47379683#47379683 http://www.mprnews.org/story/2013/05/26/environment/pesticides-suspected-in-minnesota-bee-deaths Join the summer fun in West Central Minnesota!

Our host, UThink, is retiring at the end of December 2014. This June will be the last month we post flogs here. We’ll let you know where we are moving when we find a new host! You can always learn what we are up to on our website and on twitter. Gia gave a presentation at the NU research expo. Here are the details… Hallaman, G. “Ant Diversity for Six Western Minnesota Tallgrass Prairie Remnants: The Connection between Ants and Echinacea angustifolia.” Northwestern Undergraduate Research and Arts Exposition, June 2, Evanston, IL USA, 2014 (Oral 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. 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. 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. X-ray image of 30 packets of achenes from
Echinacea angustifolia. Click on thumbnail to enlarge. 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.
