In summers 2018 and 2019, Amy mapped and collected leaf tissue from all individuals in the study areas and harvested heads from a subset of Echinacea individuals at populations in the NW corner of the Echinacea Project study area (populations: ALF, EELR, KJ, NWLF, GC, SGC, NGC, KJ, NNWLF) to map pollen movement (see Reproductive Fitness in Remnants). Amy analyzed patterns of gene flow, by assessing how individuals’ location and timing of flowering influence their reproductive success and distance of pollen movement. The now four-year-old seedlings are planted in p10.
There was no fieldwork conducted this summer but, in exciting news, Amy used the seed set data from the gene flow in remnants experiment in her dissertation chapter, “Variation in reproductive fitness among individual plants depends on the spatial proximity of prospective mates and the timing of their reproduction”. Amy defended her dissertation in May, and this chapter is currently in preparation for publication!
