A Clark’s nutcracker (Nucifraga columbiana) at the School of Biological Sciences at the University of Nebraska-Lincoln. This and other corvid species are studied to learn how cognition evolved, how animals use cognitive abilities to solve problems in nature and how cognitive abilities can affect the evolutionary process

A fisheries technician for dam owner Avista, uses a radio antenna to track tagged bull trout in a stream that feeds into Noxon Reservoir. Biologists track a handful of tagged fish daily to try and learn about their migratory movements, which a series of dams on the nearby Clark Fork River have severely impeded.
