Aims Biodiversity is traditionally studied mostly at the species level, but biogeographical and
macroecological studies at higher taxonomic levels can provide valuable insights into the …

Traditional classification of speciation modes has focused on physical barriers to gene flow.
Allopatric speciation with complete reproductive isolation is viewed as the most common …

Abstract The Millettioid/Phaseoloid (or the Millettioid) clade is a major lineage of the
subfamily Papilionoideae (Fabaceae) that is poorly understood in terms of its diversification …

Pollen, the microgametophyte of seed plants, has an important role in plant reproduction
and, therefore, evolution. Pollen is variable in, for example, size, shape, aperture number; …

Disjunct clades between the southern and the tropical Andes represent a biogeographical
pattern that has not been studied. One of the plant groups showing this disjunction is the …

We analysed 87 species of Onosma (Boraginaceae) from throughout its distribution range to
investigate its evolutionary history. Using nrDNA ITS and two plastid (rpl32‐trnL (UAG) and …

Using molecular phylogenetic data and methods we inferred divergence times and
diversification patterns for the weevil subfamily Ceutorhynchinae in the context of host-plant …

PREMISE OF THE STUDY: American amphitropical disjunction (AAD) is an important but
understudied New World biogeographic pattern in which related plants occur in extratropical …

Cryptantha, an herbaceous plant genus of the Boraginaceae, subtribe Amsinckiinae, has an
American amphitropical disjunct distribution, found in western North America and western …

Studies about the drivers of angiosperm clade diversifications have revealed how the
environment continuously alters the species chances to adapt or to go extinct. This process …
