The determinants of biodiversity patterns can be understood using macroevolutionary
analyses. The integration of fossils into phylogenies offers a deeper understanding of …

A dieback was observed on three-year-old pot-grown plants of Cycas revoluta in Sicily
(Italy). Symptoms, including stunting, yellowing and blight of the leaf crown, root rot and …

Ocean currents play a significant role in driving the long‐distance dispersal (LDD), spatial
distribution and phylogeographic patterns of many organisms. Integrating phylogeographic …

The divergence process of incipient species is fascinating but elusive by incomplete lineage
sorting or gene flow. Species delimitation is also challenging among those morphologically …

Cycads represent one of the most ancestral living seed plants as well as one of the most
threatened plant groups in the world. South China is a major center and potential origin of …

Abstract Background and Aims We conducted a comprehensive analysis of the functional
traits of leaves (leaflets) of cycads. The aim of this study was to clarify the functional …

The angiosperm family Elaeagnaceae comprises three genera and ca. 100 species
distributed mainly in Eurasia and North America. Little family-wide phylogenetic and …

Abstract Background and Aims Previous molecular dating studies revealed historical mass
extinctions and recent radiations of extant cycads, but debates still exist between …

Cycads represent an example of the success of evolutionary stasis. Despite their early
origin, they survived multiple events of mass extinction and diversified in modern tropical …

The paleotropics harbor many biodiversity hotspots and show many different species
richness patterns. However, it remains unclear which factors are the most important in …
