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 …

Phylogeographic studies base inferences on large data sets and complex demographic
models, but these models are applied in ways that could mislead researchers and …

The effects of genetic introgression on species boundaries and how they affect species'
integrity and persistence over evolutionary time have received increased attention. The …

Knowledge of tadpole morphology and natural history is essential to understand and protect
anuran diversity. We provide a regional taxonomic catalog of the tadpoles that occur in the …

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 …

Understanding historical range shifts and population size variation provides an important
context for interpreting contemporary genetic diversity. Methods to predict changes 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 …

Animal pollinators mediate gene flow among plant populations, but in contrast to well‐
studied topographic and (Pleistocene) environmental isolating barriers, their impact on …

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

The Hengduan Mountains Region (HMR) is the largest “evolutionary frontier” of the northern
temperate zone, and the origin and maintenance of species in this area is a research …
