Members of the cactus family are keystone species of arid and semiarid biomes in the
Americas, as they provide shelter and resources to support other members of ecosystems …

Oceanic islands are storehouses for unique creatures. Zoologists have long been fascinated
by island animals because they break all the rules. Speedy, nervous, little birds repeatedly …

Here, we present a review of the studies of evolutionary genetics (phylogenetics, population
genetics, and phylogeography) using genetic data as well as genome scale assemblies in …

Historic demography changes of plant species adapted to New World arid environments
could be consistent with either the Glacial Refugium Hypothesis (GRH), which posits that …

The complex geological and ecological processes that have generated high levels of
biodiversity and endemism in the Baja California Peninsula have been the subject of …

Premise Accurate species delimitation is essential for evolutionary biology, conservation,
and biodiversity management. We studied species delimitation in North American pinyon …

Unraveling the processes involved in the origin of a substantial fraction of biodiversity can
be a particularly difficult task in groups of similar, and often convergent, morphologies. The …

The state of Oaxaca is positioned in a rather unique biogeographical position with the
highest diversity of vascular plants in Mexico. The isolation of xeric valleys surrounded by …

Understanding the factors that explain the patterns of genetic structure or phylogeographic
breaks at an intraspecific level is key to inferring the mechanisms of population …

This study focuses on variation in reproductive systems in Acer (maple) species, and how
Acer might be a useful genus for understanding floral morphology and the evolution of these …
