Phylogenetic studies of Carex L.(Cyperaceae) have consistently demonstrated that most
subgenera and sections are para‐or polyphyletic. Yet, taxonomists continue to use …

The megadiverse genus Carex (c. 2000 species, Cyperaceae) has a nearly cosmopolitan
distribution, displaying an inverted latitudinal richness gradient with higher species diversity …

Disjunct distributions of flora and fauna have intrigued biogeographers for centuries and
have been central to debates over the roles that dispersal and vicariance have in speciation …

Bipolar disjunct distributions are a fascinating biogeographic pattern exhibited by about 30
vascular plants, whose populations reach very high latitudes in the northern and southern …

PREMISE OF THE STUDY: Historical patterns and processes of plants with an American
amphitropical disjunct (AAD) distribution have long interested botanists and …

Kobresia species are common in meadows on the Qinghai–Tibet Plateau. They are
important food resources for local livestock, and serve a critical foundation for ecosystem …

Abstract Changes in holocentric chromosome number due to fission and fusion have direct
and immediate effects on genome structure and recombination rates. These, in turn, may …

Sabiaceae comprises three genera and ca. 80 species with an amphi-Pacific tropical
disjunct distribution. It has been unclear whether the family is monophyletic, where the family …

PREMISE OF THE STUDY: Bipolar species represent the greatest biogeographical
disjunction on Earth, raising many questions about the colonization and adaptive processes …

Abstract Colobanthus (23 species) and Sagina (30–33 species) together are sister to
Facchinia. Whereas Facchinia is distributed in western Eurasia, Colobanthus is almost …
