In this study, we present estimates of fine-scale spatial genetic structure, mating system, and genetic diversity for both a typical grassland population and a rare understory population within an Araucaria Forest fragment.
Studied Butia eriospatha populations, GRA (open grassland in a and c), and FOR (forest in b and d).

In Mesoamerican cloud forests, such as this one in the El Triunfo Biosphere Reserve in Mexico, climate change and deforestation are leading to plant species moving upslope. However, an analysis of forest plant traits from across the tropical Americas suggests that forests are not changing fast enough to keep up with climate change.
