A new study couples an emission and transport scheme of pollen from vegetation, and explores pollen’s evolution in different atmospheric conditions and its impacts on clouds and precipitation.
To find the first direct evidence of heightened UV radiation during the end-Permian mass extinction, researchers turned to chemical evidence preserved in pollen grains.
Pollen from sediment cores shows that a now dry channel cutting through Giza was once a flowing waterway that Egyptian pyramid builders could have used to transport supplies.
Lo uses her background in atmospheric sciences to forecast pollen concentrations.
Sixty-six million years ago, an asteroid reset most of life on Earth. But without this catastrophic event, the composition of neotropical rain forests wouldn’t be the same.
Researchers hiked and rappeled into two caves in Jamaica to collect over 40 kilograms of excrement.
Physicians, public health officials, and experts in remote sensing and ecology recently met to identify ways that satellites, webcams, and crowdsourced science could help them manage asthma and allergies.
Researchers used a sediment core from a lake in California’s San Bernardino Mountains to track the effect of climate on vegetation, fire, and erosion between about 120,000 and 15,000 years ago.
A new methodology calculates the soil properties most likely to preserve pollen.
In the Andes, islands in the sky flicker, and evolution kicks into high gear.
