Population genetic and geographic data of six Neotropical plant species

We examined population genetic structure and fine-scale spatial genetic
structure (FSGS) in six perennial understory angiosperms in Andean cloud
forests of northwestern Ecuador. Species belong to three families
(Gesneriaceae, Melastomataceae, and Rubiaceae), and within each family we
paired one insect-pollinated with one hummingbird-pollinated species,
predicting that insect-pollinated species have greater population
differentiation (as quantified with the FST statistic) and stronger FSGS
(as quantified with the SP statistic) than hummingbird-pollinated species.
