Aim Carex atrofusca has an arctic–alpine distribution in the Northern Hemisphere, with only
a few, disjunct localities known in the European Alps. These alpine populations are …

Carex subg. Vignea is characterized by sessile bisexual spikes, distigmatic flowers, and the
lack of cladoprophylls. Phylogenies reconstructed using nrDNA internal and external …

Despite the controversy surrounding Cariceae generic and Carex subgeneric limits, most
debates centre on a relatively small number of highly reduced unispicate taxa. This study …

Evidence suggests that past climatic fluctuations affected speciation of extant cycads.
However, empirical genetic and morphological evidence explaining patterns and processes …

Angiosperms, a trigger for the Cretaceous Terrestrial Revolution (KTR), underwent a rapid
expansion and occupied all the environments during the Mid-Upper Cretaceous. Yet …

The role of geography and ecology in speciation are often discussed in the context of
phylogenetic niche conservatism (PNC), the propensity of lineages to retain ancestral niche …

Carex sect. Spirostachyae comprises 25 species displaying the centre of diversity in
Eurasia, while sect. Elatae comprises 22 species displaying the centre of diversity in tropical …

Many phylogenomic studies based on transcriptomes have been limited to “single-copy”
genes due to methodological challenges in homology and orthology inferences. Only a …

Succulent plants are widely distributed, reaching their highest diversity in arid and semi‐arid
regions. Their origin and diversification is thought to be associated with a global expansion …

Will the ongoing extinction crisis cause a severe loss of evolutionary information
accumulated over millions of years on the tree of life? This question has been largely …
