Mountains are among the most biodiverse areas on the globe. In young mountain ranges,
exceptional plant species richness is often associated with recent and rapid radiations …

Abstract The Early Cretaceous (145–100 million years ago (Ma)) witnessed the rise of
flowering plants (angiosperms), which ultimately lead to profound changes in terrestrial plant …

Understanding the processes that have generated the latitudinal biodiversity gradient and
the continental differences in tropical biodiversity remains a major goal of evolutionary …

The origin of extant neotropical biodiversity has been a controversial topic since the time of
Darwin. In this review, I discuss the timing of, and potential driving factors associated with …

Abstract Background and Aims As angiosperms became one of the megadiverse groups of
macroscopic eukaryotes, they forged modern ecosystems and promoted the evolution of …

This paper and this issue attempt to address how, when and why the phenomenal c.
100,000 species of seed plants in tropical America (the Neotropics) arose. It is increasingly …

One of the more vexing issues in ecology is how historical processes affect contemporary
patterns of biodiversity. Accordingly, few models have been presented. Two corollary …

There is still limited consensus on the evolutionary history of species-rich temperate alpine
floras due to a lack of comparable and high-quality phylogenetic data covering multiple plant …

Tropical alpine floras are renowned for high endemism, spectacular giant rosette plants
testifying to convergent adaptation to harsh climates with nightly frosts, and recruitment …

Dating the Tree of Life has now become central to relating patterns of biodiversity to key
processes in Earth history such as plate tectonics and climate change. Regions with a …
