Plant reproduction by means of flowers has long been thought to promote the success and
diversification of angiosperms. It remains unclear, however, how this success has come …

Floral spurs, widely recognized as a classic example of key morphological and functional
innovation and thought to have promoted the origin and adaptive evolution of many …

Background There are conflicting views between palaeobotanists and plant systematists/
evolutionary biologists regarding the occurrence of plant speciation in the Quaternary …

Although the ecological network approach has substantially contributed to the study of plant-
pollinator interactions, current understanding of their functional structure is biased towards …

Specialization has often been claimed to be an evolutionary dead end, with specialist
lineages having a reduced capacity to persist or diversify. In a phylogenetic comparative …

Understanding the processes that underpin adaptive evolutionary shifts within major
taxonomic groups has long been a research directive among many evolutionary biologists …

The exceptional species diversity of flowering plants, exceeding that of their sister group
more than 250-fold, is especially evident in floral innovations, interactions with pollinators …

Disentangling species boundaries and phylogenetic relationships within recent evolutionary
radiations is a challenge due to the poor morphological differentiation and low genetic …

Using a time-calibrated phylogenetic hypothesis including 768 Gesneriaceae species (out
of~ 3300 species) and more than 29,000 aligned bases from 26 gene regions, we test …

Flower form is one of many floral features thought to be shaped by pollinator-mediated
selection. Although the drivers of variation in flower shape have often been examined in …
