Ancient plankton communities stressed before mass extinction

Changes in our modern ecosystems, such as declines in biodiversity and invasive species, are similar to those that preceded the first of Earth’s mass extinctions about 443 million years ago, according to a new study. Researchers recently found that ancient plankton communities began to show environmental stress nearly 400,000 years before the extinction, as the planet cooled.
