Plants have evolved several ways to deal with heavy metals that might otherwise poison or kill them.
People wouldn’t last long without the countless other species we depend on for survival.
Plants lose huge amounts of water to catch the carbon dioxide they need for photosynthesis – but a new discovery may make them more efficient.
Thanks to their high concentrations of phytoplankton, African lakes emit less CO2 than their boreal counterparts, with important consequences for climate modelling.
More carbon dioxide in the air doesn’t necessarily mean more growth for trees, and the increasing risk of wildfires and drought has major consequences, as an interactive map shows.
Rising carbon dioxide in the atmosphere may be a boon for maize crops in tropical growing regions like those found in much of Africa.
Variegated plants can be more expensive than their all-green counterparts. But there are ways to protect your investment.
New research shows that coast redwood trees have a surprising adaptation that helps them thrive in both wet and dry environments.
The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.
Southern Tasmania’s cool climate was thought to be a climate refuge for tall forests. But that may no longer be true.
Though you might not think so to look at them, plants have a busy day.
Plants need light to feed themselves, so they grow in ways that help them collect as much of it as they can. Sometimes that’s straight up, but not always.
David Attenborough’s new BBC documentary The Green Planet shows plants are stranger than they first appear.
A billion-year-old ‘hydrogen economy’ in the frozen soil of Antarctica provides bacteria with energy, water, and the carbon that makes up their bodies.
We are not at risk of running out of oxygen due to climate change, but ocean creatures are – and that will harm the whole planet.
If a major new study is right, then even our most cautious climate projections have likely been optimistic.
Warmer temperatures cannot increase the amount of carbon deciduous trees absorb in each growing season, a new study suggests.
How ancient microbes survived in a world without oxygen has been a mystery. Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration.
The last time global carbon dioxide levels were around 400ppm was four million years ago. On average, the world was 3℃ warmer, but in high northern latitudes, it was up to 14℃ warmer than today.
Microscopic ocean phytoplankton feed a “biological pump” that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
