image: The root vole (Microtus oeconomus) is often a dominant species in rodent communities, inhabiting various types of wet grasslands. Continent-scale collapses in population cycles of this species and other grass-eating voles could have profound effects on predators and on other components of the food web. This image relates to a paper that appeared in 5 April, 2013, issue of Science, published by AAAS. The paper, by Thomas Cornulier at the University of Aberdeen in Aberdeen, UK, and colleagues was titled, "Europe-Wide Dampening of Population Cycles in Keystone Herbivores." view more
