In summers 2018 and 2019, I mapped and collected leaf tissue from all individuals in the study areas and harvested seedheads from a subset of Echinacea individuals at populations in the NW corner of the study area (populations: ALF, EELR, KJ, NWLF, GC, SGC, NGC, KJ, NNWLF) to map pollen movement (see Reproductive Fitness in Remnants). To analyze patterns of gene flow, I will assess how individuals’ location and timing of flowering influence their reproductive success and distance of pollen movement. I am currently wrapping up genotyping the DNA from the leaf tissue samples and a subset of the seeds I collected. This summer, the team measured the 3-year-old seedlings from the gene flow study that are planted in exPt10. I did not do additional field work for this project this year.
- Start year: 2018
- Location: Roadsides, railroad rights of way, and nature preserves in and around Solem Township, MN
- Overlaps with: Reproductive Fitness in Remnants, Phenology in the Remnants
- Data collected: exPt10 measure data is in the cgdata repo.
- Products: I presented a poster based on the locations and flowering phenology of individuals from summer 2018 at the International Pollinator Conference in Davis, CA this summer. The poster is linked here: https://echinaceaproject.org/international-pollinator-conference/.
