The capacity of the Amazon forest to store carbon in a changing climate will ultimately be determined by how fast trees die – and what kills them. Now, a huge new study has unraveled what factors control tree mortality rates in Amazon forests and helps to explain why tree mortality […]

A recent study examining carbon storage in Pacific Northwest forests demonstrated that although large-diameter trees (21 inches) only comprised 3% of total stems, they accounted for 42% of the total aboveground carbon storage. The researchers highlight the importance of protecting large trees and strengthening existing forest management policies so that […]

Progeny of novel combination is more vigorous and productive than parental plants. Novel grafted plants — consisting of rootstock epigenetically modified to “believe” it has been under stress — joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive, and resilient than the […]

Rubisco is the most abundant enzyme on the planet. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it’s central to the process of carbon fixation and is one of Earth’s oldest carbon-fixing enzymes. Researchers at UC Davis and LBNL have now discovered an alternative form […]

The study is the first to measure vegetation changes across the Arctic tundra, from Alaska and Canada to Siberia, using satellite data from Landsat, a joint mission of NASA and the U.S. Geological Survey.
