The evolution and radiation of angiosperms and Gnetales
The Cretaceous is a time of extensive change in terrestrial life. During a relatively short time interval, starting about 130 million years ago, modern ecosystems emerged, replacing the ancient Mesozoic communities. The Early Cretaceous changes were particularly manifested in the dramatic diversification of flowering plants, but several other modern groups proliferated at the same time. Understanding the timing, origin and early diversification of flowering plants and other contemporaneous plant groups has for a long time been a major focus of our research. The research is grouped in several subthemes:
