Abstract The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the
state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos …

For centuries, scientists have recognized and worked to understand how Earth's mutable
landscape and climate shape the distribution and evolution of species. Here, we describe …

Mexico is considered an exceptional biogeographic area with a varied endemic flora,
however spatial phylogenetic measures of biodiversity have not yet been estimated to …

Most phylogenies are typically represented as purely bifurcating. However, as genomic data
have become more common in phylogenetic studies, it is not unusual to find reticulation …

Around the world, many species are confined to “Sky Islands,” with different populations in
isolated patches of montane habitat. How does this pattern arise? One scenario is that …

Premise Although numerous phylogenetic studies have been conducted in Cactaceae,
whole‐plastome datasets have not been employed. We used the chollas to develop a …

The genus Abies is distributed discontinuously in the temperate and subtropical montane
forests of the northern hemisphere. In Mesoamerica (Mexico and northern Central America) …

Divergence is often ephemeral, and populations that diverge in response to regional
topographic and climatic factors may not remain reproductively isolated when they come into …

Background The age of lineages has become a fundamental datum in studies exploring the
interaction between geological transformation and biotic diversification. However …

Aim We explored lineage diversification within desert‐dwelling fauna. Our goals were (1) to
determine whether phylogenetic lineages and population expansions were consistent with …
