What is it about?

This original article for the first time reveals plant evolutionary and ecological responses to the climate cooling across the Cretaceous-Paleogene boundary in the phylogenetic context, which will stimulate our understanding of biological feedback on climate change in the past.

Why is it important?

These findings not only interpret how specific plant taxa responded to the cooling across the K-Pg boundary, but also provide a reversed case study for the scientific community to speculate and comprehend how to conserve plant biodiversity for human sustainable development under the global warming today.


This work provides for the first time how plant lineages responded to the cooling across the K-Pg boundary in the changes of morphological characters and distribution ranges, which will expand our knowledge of the bio-adaptation to climate changes.
