Abstract Stachyuraceae, an East Asian endemic family of shrubs or small trees, comprises a
single genus, Stachyurus (c. 11 spp.). Despite previous extensive studies based on both …

Species concept and delimitation are fundamental to taxonomic and evolutionary studies.
Both inadequate informative sites in the molecular data and limited taxon sampling have …

Phenotypic polymorphism within a species is a notable phenomenon in evolutionary biology
to understand the process of adaptive speciation and other historical events. The Saxifraga …

Premise of research. The disjunct distribution of plant genera between eastern Asia (EA)
and eastern North America (ENA) has long attracted the attention of biologists and …

Informed species delimitation is crucial in diverse biological fields; however, it can be
problematic for species complexes. Showing a peripatric distribution pattern, Stewartia …

Tertiary relicts often show evolutionary stasis in morphology and ecology and have been
hypothesized to retain stable population sizes in refugia. However, recent studies have …

Phylogenetic analyses using diverse datasets can yield conflicting inference of evolutionary
history. Phylogenetic conflicts observed in both animal and plant systems have often been …

Numerous temperate plants and animals on the Qinghai-Tibet Plateau (QTP) are
hypothesized to have differentiated due to vicariant allopatric speciation associated with the …

Understanding how species adapt to extreme environments is an extension of the main
goals of evolutionary biology. While alpine plants are an ideal system for investigating the …

Stachyuraceae consist of a single genus Stachyurus with about ten species endemic to
eastern Asia. The family was recently shown to be sister to the western North American …
