Phylogeographic studies have merged different disciplines to explain speciation processes
at both spatial and time scales. Although the number of phylogeographic extant studies has …

The roles of intra‐and interspecific gene flow in speciation and species evolution are topics
of great current interest in molecular ecology and evolutionary biology. Recent modelling …

Abstract The Atlantic rainforest of Brazil harbors outstanding species richness and levels of
endemism, representing one of the most biodiverse regions on Earth. Yet, a lot is still …

The present study uses published phylogeographical studies to test the Carnaval–Moritz
(CM) model of forest dynamics in the Atlantic forest of Brazil. The model predicts that a large …

Ecological and evolutionary studies largely assume that island populations display low
levels of neutral genetic variation. However, this notion has only been formally tested in a …

The Pampas in the southern Neotropics is a vast region with vegetation composed mainly of
grasses, and it may be the least-studied ecosystem in southern South America. Contrary to …

Bromeliaceae is a morphologically distinctive and ecologically diverse family originating in
the New World. Three centers of diversity, 58 genera, and about 3,140 bromeliad species …

Understanding the genetic diversity and population structure of Hevea is of great importance
for managing its conservation and for utilization of rubber genetic resources. In this study, we …

Pollinators can be a limited resource and natural selection should favour differences in
phenotypic characteristics to reduce competition among plants. Bats are important …
