Changing patterns of genetic differentiation in the slender wild oat, Avena barbata.

Proceedings of the National Academy of Sciences of the United States of America - 4 Oct 2022

Latta Robert G, Crosby Kate, Hamrick James L

Abstract excerpt

The slender wild oat (Avena barbata) was widely studied in California using allozymes in the 1970s and interpreted as a case of ecotypic adaptation to contrasting moisture environments. However, common garden studies suggested that the moist-associated ("mesic") ecotype had high fitness in both moist and dry habitats, thus predicting an adaptive spread into areas occupied by the dry associated ("xeric") ecotype....
