Clarkia in space and time

Population genomics of contemporary adaptation across a species' range

We’re using pool-seq across ~100 populations of Clarkia xantiana — sampled both historically and contemporaneously — to ask how allele frequencies have shifted over recent decades of climate change, and whether the same loci respond to climate across populations and across time. The work leverages long-term demographic and herbarium records from the Moeller and Geber labs, together with newly assembled reference genomes (see Clarkia reference genomes).

With Dave Moeller (Minnesota), Monica Geber (Cornell), and Jacob Landis (Cornell).
