An abnormally hot year can significantly suppress growth in grasslands, a stifling effect that lingers well into the next year even if temperatures return to normal. It can also hinder how well the grasslands absorb carbon dioxide from the atmosphere.Published: Wednesday, September 17th, 2008Found in: Biology, Botany, Climate Change and Life

A new study provides strong evidence that fruits harm predators with the same chemicals that, for example, give chili peppers their spice.Published: Monday, August 11th, 2008Found in: Botany, Ecology and Life -
Pathogens hitchhike on commercial bees that escape from greenhouses. These escapees bring disease to wild bumblebees.Published: August 16th, 2008; Vol.174 #4Found in: Agriculture, Biology, Botany and Life -
The parasitic vine known as dodder really sucks. It pierces the tissue of other plants — some of which are important crops — extracting water and nutrients needed for its own growth. But it also consumes molecules that scientists could manipulate to bring on the parasite’s demise.Published: August 16th, 2008; Vol.174 #4Found in: Agriculture, Biology, Botany and Life -
