Recently diverged species may hybridize in their contact zones if complete reproductive
isolation has not yet emerged. Petunia inflata and P. interior are closely related species with …

Hybridization between closely related plant species is a widespread phenomenon with
significant evolutionary consequences, so natural hybrid zones provide exciting …

Delimiting species is challenging in recently diverged species, and adaptive radiation is
fundamental to understanding the evolutionary processes because it requires multiple …

Background Theory suggests that the genetic architecture of traits under divergent natural
selection influences how easily reproductive barriers evolve and are maintained between …

ABSTRACT A new species of Petunia (Solanaceae) is described and illustrated for the
Brazilian flora. Petunia toropiensis Stehmann & Larocca is known only from a few sites …

The long-term success of populations is dependent on individual reproductive success, and
in general, increased population size and genetic diversity contribute to population …

Pterodon emarginatus Vogel and P. pubescens (Benth.) Benth. are phylogenetically related
trees that compose a clade of sister species abundant in the Brazilian Savanna. Despite …

Delimiting species is challenging in recently diverged species, and adaptive radiation is
fundamental to understanding the evolutionary processes because it requires multiple …

An accurate taxa delimitation, based on a full understanding of evolutionary processes
involved in taxon differentiation, can be gained from a combination of ecological …

Understanding the association between molecular data and the evolutionary forces induced
by the environment is an important method to improve the knowledge on the species spatial …
