Under higher CO2 levels, plants take up more toxic materials

Higher concentrations of CO2 in the atmosphere generally increase plant growth and productivity. Plants take up more nutrients from the soil. But according to a new study, they also take up more toxic materials from the soil. Benjamin Duval from the University of Illinois at Urbana-Champaign and colleagues showed in a paper published this month in the journal Environmental Science & Technology that contaminants in the soil become increasingly mobile in vegetation and that these toxins could be... [Read more]

Plants moving downhill in response to climate change

Higher temperatures are forcing species to take to cooler climes at higher elevations, the prevailing wisdom goes. But changes in precipitation also drive change, and in the case of plant species in the Northern Hemisphere, the movement may be driven downhill, not up. That’s according to a recent study published in the journal Science by a team of researchers led by Shawn Crimmins at the Department of Forest Management, at the University of Montana. The study looked at the distribution of 64... [Read more]

Plants are complicated

Planting trees, as everyone knows, is a good way to offset climate change. The more greenery on Earth, the better, since vegetation act as carbon sinks, essentially sucking up the excess CO2 and storing it in leaves, stems, and root systems. But a recent paper published in the journal Nature Geoscience claims we have a long way to go towards understanding the biochemical processes in which plants interact with the climate. Simply looking at the carbon cycle involving plants is not enough, say the... [Read more]
