Predators keep the world green, ecologists find

Predators are, ironically, the key to keeping the world green, because they keep the numbers of plant-eating herbivores under control, reports a research team lead by John Terborgh, a professor of environmental science at Duke University's Nicholas School of the Environment and Earth Sciences. Th...

Internet viruses help ecologists control invasive species

Studying how computer viruses spread through the internet is helping ecologists to prevent invasions of non-native species.
