Protecting Pollinators — With rapidly growing concerns over pollinators, public interest has led to much debate on how to help protect them. Because pollinators are such an amazingly diverse group of organisms, both taxonomically and ecologically, their conservation is both extremely complex and important. Join Adrian Carper, a postdoctoral researcher and lecturer in the Department of Ecology and Evolutionary Biology, as he reviews the many types of Colorado’s pollinators and together explore their biologies, natural histories, and conservation statuses. As a researcher studying pollinators, he will then review some of the impediments to pollinator conservation, including some of the biggest threats to Colorado’s pollinators, and discuss how through both research and public involvement, we can help inform and impact their conservation right here in Colorado; 6:15 p.m., Sept. 17, CU Museum of Natural History, 15th and Broadway, Boulder; free; 303-492-6892.
