- Scientists rethink how much carbon forests can store
Scientists found that oak trees continue photosynthesis after their annual growth stops, suggesting forests may not store as much carbon as previously assumed. The study, published in Science Advances, indicates climate models might overestimate carbon storage by assuming increased photosynthesis directly translates to tree growth.
- Oak trees are delaying spring to starve caterpillars
Oak trees delay leaf growth to starve caterpillars, reducing insect survival and leaf damage. This defense mechanism is more efficient than chemical defenses. Oak trees can delay leaf growth by just three days to achieve this effect.
