Polyploidy in the Conifer Genus Juniperus: An Unexpectedly High Rate
Recent research suggests that the frequency of polyploidy may have been underestimated in gymnosperms. While there are few reports of polyploids in the genus Juniperus, data are still missing for most species. In this study, we evaluated the extent of polyploidy in Juniperus by conducting the first comprehensive screen across...Farhat, Perla ; Hidalgo, Oriane ; Robert, Thierry ; Siljak-Yakovlev, Sonja ; Leitch, Ilia …

Plastid phylogenomic insights into the evolution of Caryophyllales
The Caryophyllales includes 40 families and 12,500 species, representing a large and diverse clade of angiosperms. Collectively, members of the clade grow on all continents and in all terrestrial biomes and often occupy extreme habitats (e.g., xeric, salty). The order is characterized by many taxa with unusual adaptations including carnivory,...Yao, Gang ; Jin, Jian-Jun ; Li, Hong-Tao ; Yang, Jun-Bo ; Mandala, Venkata …

Phytolith-based environmental reconstruction from an altitudinal gradient in Mpumalanga, South Africa, 10,600 BP–present
Studying vegetation change across biome boundaries provides insight into vegetation resilience. In this study, shifts in grassland composition are reconstructed from sediments in three wetland sites across altitudinal gradient from 2128 to 897 m.a.s.l., representing a gradient from the grassland biome to the grassland/savanna boundary in the Mpumalanga region, north-eastern South...Breman, Elinor ; Ekblom, Anneli ; Gillson, Lindsey ; Norström, Elin
