Repeated upslope biome shifts in Saxifraga during late-Cenozoic climate cooling.
Mountains are among the most biodiverse places on Earth, and plant lineages that inhabit them have some of the highest speciation rates ever recorded. Plant diversity within the alpine zone - the elevation above which trees cannot grow—contributes significantly to overall diversity within mountain systems, but the origins of alpine... -

Evolutionary history, traits, and weediness in Digitaria (Poaceae: Panicoideae).
Digitaria is a large pantropical genus, which includes a number of economically problematic agricultural weeds. Difficulties in species identification and the circumscription of the genus have previously hindered progress in understanding its evolution and developing a stable classification. We investigate the evolutionary history of Digitaria by combining two approaches: (i)... -

The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation.
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ from each other and from the species tree. The effect of these topological incongruences...Carruthers, Tom ; Sun, Miao ; Baker, William J. ; Smith, Stephen A. ; de Vos, Jurriaan M. …
