Terrestrial Ecosystems in the Past 100 Million Years


Terrestrial ecosystems are the large‐scale associations of the biological communities living on land. Although the last 100 million years represent only a small fraction (perhaps 2%) of the earth's history, revolutionary changes in terrestrial life occurred during this period.
