Villalobos-Barrantes H. M., Meriño B. M., Walter H. E., Guerrero P. C., Independent Evolutionary Lineages in a Globular Cactus Species Complex Reveals Hidden Diversity in a Central Chile Biodiversity Hotspot, Genes, 2022, 13(2):240, doi: 10.3390/genes13020240
This study of the Eriosyce curvispina complex combines a five-region DNA phylogeny with 12 microsatellite markers in nine populations. It reveals independent lineages and geographically structured variation. The authors discuss consequences for species delimitation and conservation while leaving formal nomenclatural changes to subsequent research.
