Campaigns by zoos, aquariums, and other civil society organizations are an important tool for promoting social changes that benefit the environment. Here, we evaluate a global biodiversity education campaign's impact through a repeated-measures survey of nearly 5000 visitors to 20 zoos and aquariums located in 14 countries.

Flood of Mud: The Roanoke River -- Past and Future is a video project examining long-term impacts of historic land clearing and erosion on temperate rivers and their floodplains. The 17-minute video targets youth and adult visitors to the North Carolina Aquariums. The video highlights the NSF-funded research project EAR-0105929, "Modeling the Impacts of Post-settlement Sediment Deposition on Floodplain Vegetation," which applies paleoecological and dendrochronological methods and computer modeling to examine and predict the impact of sedimentation on forest composition, productivity and functioning of the lower Roanoke River in North Carolina.
