Temperate woody plants in the Northern Hemisphere have long been known to exhibit high
species richness in East Asia and North America and significantly lower diversity in Europe …

Premise of the Study A key question in evolutionary biology is why some clades are more
successful by being widespread geographically, biome diverse, or species‐rich. To extend …

speciose Magnolioideae with approximately 300 species in varying numbers of genera and …

Hybridization caused by frequent environmental changes can lead both to species
diversification (speciation) and to speciation reversal (despeciation), but the latter has rarely …
