Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …

Detecting Introgressed Populations in the Iberian Endemic Centaurea podospermifolia through Genome Size.
Based on results from previous studies, populations of the Iberian endemic Centaurea podospermifolia north of the Ebro River are considered genetically pure, while those southward are introgressed, with genetic input from C. cephalariifolia. This phenomenon is particularly relevant, especially given both the endangered and protected status for the species, which... -

Hybridization: a ‘double-edged sword’ for Neotropical plant diversity.
Hybridization can facilitate both evolutionary diversification and extinction and has had a critical role in plant evolution, with c. 25% of species known to hybridize in some temperate floras. However, in the species-rich Neotropical flora, the role of hybridization in the evolution of diversity remains unclear. Our review examines studies...Schley, Rowan J ; Twyford, Alex D ; Pennington, R Toby

Mediterranean Subspecies versus Californian Varieties: An Example from Acmispon (Leguminosae, Loteae).
The tribe Loteae of the family Leguminosae has major centers of diversity in the Mediterranean Region and California. It is used here to illustrate different traditions of taxonomic interpretation of infraspecific variation among researchers in different continents. Recent accounts of European and Mediterranean taxa commonly make an emphasis on recognizing...Sokoloff, Dmitry D. ; Akulova-Barlow, Zoya V. ; Govaerts, Rafaël
