Myriad branches in the tree of life are intertwined through ecological relationships. Biologists
have long hypothesized that intimate symbioses between lineages can influence …

When lineages of hosts and microbial symbionts engage in intimate interactions over
evolutionary timescales, they can diversify in parallel (ie, co‐diversify), producing …

Summary The Andean mountains of South America are the most species‐rich biodiversity
hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land …

Orchids constitute one of the most spectacular radiations of flowering plants. However, their
origin, spread across the globe, and hotspots of speciation remain uncertain due to the lack …

High‐throughput sequencing is helping biologists to overcome the difficulties of inferring the
phylogenies of recently diverged taxa. The present study analyzes the phylogenetic signal of …

Rapid evolutionary radiations are among the most challenging phylogenetic problems,
wherein different types of data (eg, morphology and molecular) or genetic markers (eg …

Abstract Background The genus Ligusticum consists of approximately 60 species distributed
in the Northern Hemisphere. It is one of the most taxonomically difficult taxa within Apiaceae …

Quercus acutissima, an important endemic and ecological plant of the Quercus genus, is
widely distributed throughout China. However, there have been few studies on its …

The concordance of evolutionary histories and extant species interactions provides a useful
metric for addressing questions of how the structure of ecological communities is influenced …

PREMISE The inference of evolutionary relationships in the species‐rich family Orchidaceae
has hitherto relied heavily on plastid DNA sequences and limited taxon sampling. Previous …
