DOIAbstract
Baripus is a ground beetle genus endemic to southern South America, currently distributed across grassland and shrub habitats in mountain and lowland regions. The species of this genus are known to have been affected by the Andean orogeny and the climate changes that occurred during this process. In this study, we seek to understand how the orogeny of the Andes may have led to changes in the climatic niches of the species of Baripus over time. We integrated former ecological and historical biogeographic hypotheses, exploring the use of parsimony optimization of phylogenetically structured climate variables and ancestral character state reconstruction methods. We then performed regression analyses of the optimized climatic niche variables wi...
