The gradual heterogeneity of climatic factors pose varying selection pressures across geographic distances that leave signatures of clinal variation in the genome. Separating signatures of clinal adap
The timing of germination is a key life-history trait in plants, which is strongly affected by the strength of seed dormancy. Continental-wide genetic variation in seed dormancy has been related to
Human-facilitated introductions of nonnative populations can lead to secondary contact between previously allopatric lineages, resulting in either homogenization of the lineages or stable hybrid zones
