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... -

Occurrence-based diversity estimation reveals macroecological and conservation knowledge gaps for global woody plants.
Incomplete sampling of species’ geographic distributions has challenged biogeographers for many years to precisely quantify global-scale biodiversity patterns. After correcting for the spatial inequality of sample completeness, we generated a global species diversity map for woody angiosperms (82,974 species, 13,959,780 occurrence records). The standardized diversity estimated more pronounced latitudinal and... -

Truongsonia (Arecaceae: Arecoideae: Truongsonieae)—a new palm genus and tribe from Vietnam.
A genus and species of palm from the Truong Son Range in Vietnam, Truongsonia lecongkietii, is described as new to science. Phylogenomic analysis strongly supports the placement of the new taxon in subfamily Arecoideae as sister to the African endemic tribe Podococceae, which comprises a single genus Podococcus. A new... -

Six new species of Maesa (Primulaceae) from Papua New Guinea.
Six new species of Maesa (Primulaceae-Maesoideae) from Papua New Guinea, namely M. angustibracteolata, M. aurulenta, M. brassii, M. oblanceolatifolia, M. pusilliflora and M. prolatifructa are described and illustrated based on observations from herbarium specimens; the taxonomic affinities of each species are also discussed.Sumanon, Pirada ; Eiserhardt, Wolf L. ; Balslev, Henrik ; Utteridge, Timothy M.

Global beta-diversity of angiosperm trees is shaped by Quaternary climate change.
As Earth’s climate has varied strongly through geological time, studying the impacts of past climate change on biodiversity helps to understand the risks from future climate change. However, it remains unclear how paleoclimate shapes spatial variation in biodiversity. Here, we assessed the influence of Quaternary climate change on spatial dissimilarity...Xu, Wu-Bing ; Guo, Wen-Yong ; Serra-Diaz, Josep M. ; Schrodt, Franziska ; Eiserhardt, Wolf L. …

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. …
