Project Fossil Atmospheres and Ginkgo leaves
Project Fossil Atmospheres
The project Fossil Atmospheres is about how the cells of leaves on ginkgos have changed over time, and to learn more about the ancient atmosphere of the Earth.
The first species of Ginkgo evolved in the Permian, before the dinosaurs, survived three mass extinctions, and one species is still living today. It is an ideal plant to study because it can provide a record from 300 million years ago through to the present.
By comparing the stomata of fossilized and modern ginkgo leaves, researchers and citizen scientists hope to understand how ginkgo leaves have already changed and how they may change in the future. There have been many different species of Ginkgo, but they all belong to one genus and the leaves are recognizably similar in all the different species.
This ginkgo grove at the Smithsonian Environmental Research Center in Edgewater, Maryland, is part of the experiment.
15 Ginkgo biloba trees are growing in open-topped chambers in natural field conditions, under modern & futuristic CO2: 400, 600, 800 and 1000 ppm.
