Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.
