The present paper reviews advances in the study of two major intercontinental disjunct
biogeographic patterns:(i) between Eurasian and western North American deserts with the …

The cacti are one of the most celebrated radiations of succulent plants. There has been
much speculation about their age, but progress in dating cactus origins has been hindered …

Understanding the timing of mountain building and desert formation events in western North
America is crucial to understanding the evolutionary history of the diverse arid-adapted biota …

Succulent plants are widely distributed, reaching their highest diversity in arid and semiarid
regions. Their origin and diversification is thought to be associated with a global expansion …

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

The Boraginales are now universally accepted as monophyletic and firmly placed in
Lamiidae. However, a consensus about familial classification has remained elusive, with …

We integrate climatic niche models and dated phylogenies to characterize the evolution of
climatic niches in Oenothera sections Anogra and Kleinia (Onagraceae), and from that we …

A comprehensive analysis of photosynthetic pathways in relation to phylogeny and
elevational distribution was conducted in Bromeliaceae, an ecologically diverse Neotropical …

The evolution of C 4 photosynthesis requires an intermediate phase where photorespiratory
glycine produced in the mesophyll cells must flow to the vascular sheath cells for …
