2017 update: Dykstra’s local adaptation experiment

This summer, Amy and members of Team Echinacea continued to monitor the progress of Echinacea plants in her local adaptation plots. We found 221 basal plants, but no flowering plants this year. Amy has 3 sites: Western South Dakota, Central South Dakota, and West Central Minnesota. At each site achenes from all sites have been sowed. Team Echinacea is able to help with the assessment of survival and fitness traits of the individuals in the Minnesota plot.

Amy presents her local adaptation research so far at lunch this summer.

Start year: 2008

Location: Grand River National Grassland (Western South Dakota), Samuel H. Ordway Prairie (Central South Dakota), Staffanson Prairie Preserve (West Central Minnesota), and Hegg Lake WMA (West Central Minnesota).

Overlaps with: Dykstra’s interpopulation crosses

Data collected:  Plant fitness measurements (plant status, number of rosettes, number of leaves, and length of longest leaf)
