Chromosomal rearrangements (CRs) have been known since almost the beginning of
genetics. While an important role for CRs in speciation has been suggested, evidence …

Summary Oaks (Quercus, Fagaceae) are the dominant tree genus of North America in
species number and biomass, and Mexico is a global center of oak diversity. Understanding …

Background Two indicators of a clade's success are its diversity (number of included
species) and its disparity (extent of morphospace occupied by its members). Many large …

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

Species richness varies immensely around the world. Variation in the rate of diversification
(speciation minus extinction) is often hypothesized to explain this pattern, while alternative …

Abstract Knowledge about the mycorrhizal root traits of plants is critical for understanding
ecosystem processes from landscape to global scale. In spite of> 130 years of research …

Determining phylogenetic relationships among very closely related species has remained a
challenge for evolutionary biologists due to interlocus phylogenetic discordance and the …

Repetitive elements can cause large‐scale chromosomal rearrangements, for example
through ectopic recombination, potentially promoting reproductive isolation and speciation …

Most of the world's terrestrial biome types can be found in China. To systematically
investigate species composition and structure of China's forest communities, we launched a …

Carex (Cyperaceae), with an estimated 2000 species, nearly cosmopolitan distribution and
broad range of habitats, is one of the largest angiosperm genera and the largest in the …
