Cedar Waxwing Bird (IMAGE) Penn State Caption Invasive fruiting plants sometimes can be beneficial to an ecosystem, contrary to prevailing ideas, according to research by Penn State University scientists to be published during 2011 in the journal Diversity and Distributions. The discovery is expected to affect the prevailing approach to ecosystem maintenance, which typically involves efforts to eliminate non-native, invasive shrubs.
