Researchers working on the population genetics of zooplankton—small marine animals—during a Bering Sea Ecosystem study discovered that a key copepod is a different but closely related species to the temperate species reported previously. As tiny crustaceans, copepods are an important link in the ecosystem, transferring energy from the plants at the base of the food web to fish. Identifying the exact copepod species that inhabits the Bering Sea will help researchers better understand changes occurring in this highly productive region. Image: Matt Wilson and Jay Clarke
