Species distribution modeling and molecular markers suggest longitudinal range shifts and cryptic northern refugia of the typical calcareous grassland species <i>Hippocrepis comosa</i> (horseshoe vetch).

There were highly significant positive correlations between DW and all genetic variation measures ( r = .729413, p < .0001, t = 6.3977), meaning that a high number of rare markers (high DW) were associated with high genetic variation.
