The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted
the attention of naturalists for centuries. Despite major advances in recent years in our …

Hybridization can facilitate both evolutionary diversification and extinction and has had a
critical role in plant evolution, with c. 25% of species known to hybridize in some temperate …

The American tropics (the Neotropics) are the most species-rich realm on Earth, and for
centuries, scientists have attempted to understand the origins and evolution of their …

Recent debates on the number of plant species in the vast lowland rain forests of the
Amazon have been based largely on model estimates, neglecting published checklists …

The Amazonian landscape evolution is the result of the combined effect of Andean
tectonism, climate and the Earth's interior dynamics. To reconstruct the landscape evolution …

Coevolutionary models suggest that herbivores drive diversification and community
composition in plants. For herbivores, many questions remain regarding how plant defenses …

Ecological theory predicts that the high local diversity observed in tropical forests is
maintained by negative density–dependent interactions within and between closely related …

Evaluating the factors that drive patterns of population differentiation in plants is critical for
understanding several biological processes such as local adaptation and incipient …

The forests of Amazonia are among the most biodiverse plant communities on Earth. Given
the immediate threats posed by climate and land-use change, an improved understanding of …

The Cerrado is a biodiversity hotspot in central Brazil that is the largest expanse of savanna
in the Neotropics. Here, we aim to identify and delimit biogeographic districts within the …
