Cultural use of tropane alkaloids of Brugmansia species and cultivars in Colombia depends on local plant growth environment rather than genetic diversity

The paper shows that tropane alkaloid content and use of Brugmansia species in Colombia depend on local environmental factors, not genetic diversity.

Allopatric speciation is more prevalent than parapatric ecological divergence in a recent high-Andean diversification (Asteraceae: Linochilus)

The study tests whether allopatric or parapatric ecological divergence drives speciation in the paramo genus Linochilus, finding allopatric speciation is more prevalent.

The Nature of Espeletia Species

This study examines whether Espeletia species are distinct natural groups or arbitrary divisions by analyzing phenotypic and genomic data from 538 specimens, finding low concordance between phenotypic groups and genomic clusters.
