Leaf fossils show severe end-Cretaceous plant extinction in Patagonia（图）
Leaf fossils severe end-Cretaceous plant extinction Patagonia
2021/1/18
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants they relied on for food. Fossil leaf assemblages from Patagonia su...
Ecology team finds leaf litter has slower decomposition rate in warm temperatures than previously estimated
Ecology team leaf litter slower decomposition rate warm temperatures previously estimated
2017/7/19
The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists. Using leaf litter data in streams from ...
