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 …

Context A comprehensive understanding of how rapidly changing environments affect
species gene flow is critical for mitigating future biodiversity losses. While recent …

Aim Phylogeographic studies show how historical and current changes in landscapes shape
the geographic distribution of genetic diversity in species of animals and plants. In particular …

The combination of niche modelling and landscape genetics (genomics) helps to
disentangle processes that have shaped population structure in the evolutionary past and …

Local adaptation is important when predicting arthropod‐borne disease risk because of its
impacts on vector population fitness and persistence. However, the extent that vector …

Abstract Systematic revisions of South American marsupials have contributed to our
knowledge about genus and species diversity in the last decades, including studies of the …

The riverine barrier hypothesis has been extensively explored in Neotropical rainforests,
while its importance in drier regions such as the Caatinga, a seasonally dry tropical forest in …

Context Rivers, landscape, and climate can alter patterns of gene flow and consequently,
shape intraspecific genetic variation. While rivers are predicted to halt gene flow in terrestrial …

Abstract Aim Knowledge about the Neotropical dry formations, particularly the Caatinga,
remains rudimentary compared to other biotas in the region. Here we address several …

Recent advances in the field of landscape genetics provide ways to jointly analyze the role
of present-day climate and landscape configuration in current biodiversity patterns …
