Abstract The South American Dry Diagonal, also called the Diagonal of Open Formations, is
a large region of seasonally dry vegetation extending from northeastern Brazil to northern …

In the 21st century, phylogeography has experienced dramatic growth in the data and
methods used by the field. Insect (more generally, hexapod) phylogeography has …

Phylogeography investigates historical drivers of the geographical distribution of
intraspecific lineages. Particular attention has been given to ecological, climatic and …

The Caatinga biogeographical region, located in the semi-arid region of northeastern Brazil,
is characterized by high levels of cactus diversity and endemism. In this study, we …

Climate change is a major threat to ecosystems and global biodiversity, directly impacting
spatial species distribution. Using a species distribution modeling approach to predict …

The Drosophila repleta group is an array of more than 100 species endemic to the “New
World”, many of which are cactophilic. The ability to utilize decaying cactus tissues as …

Cactus species are well represented in arid and semiarid environments, where they
sometimes even dominate the landscape, forming true cactus forests. In this review, we …

Hybridization and introgression are processes that contribute to shaping biological diversity.
The factors promoting the formation of these processes are multiples but poorly explored in …

Pleistocene climatic changes have played a major role in the evolution of Brazilian Atlantic
Forest and South America biodiversity but their impacts on the genetic structure of widely …

Evolutionary processes related to climatic changes and ecological factors, such as
microhabitat affinities and food specialization, can be important contributors to …
