Genetics and bee conservation: telling the full story of a species’ decline

We’ve all probably watched bees engage in pollination as they move from flower to flower collecting pollen. This process is essential to the reproduction of many plants, including crops. When most people think of pollinators, they think of the honey bee (Apis mellifera). However, more than 20,000 species of bees have been described—all of which are pollinators! In fact, honey bees are actually native to southeast Asia and have spread across the globe due to human activities, potentially competing with other bees. Despite the honey bee’s ubiquity and popularity, native bees are important pollinators because ecological adaptations that differ from those of honey bees. For example, the tongues of many native bees such as bumble bees can reach the nectar of longer flowers for pollination better than the honey bee.

Why YY Males? Using Hatchery Brook Trout to Eliminate an Invasive Species

Brook Trout were first introduced to the American West in the early 1900s. Since then, they have hurt native fish populations through competition and predation. In this study, scientists examine the effectiveness of using genetic technology to shift the ratio of male to female Brook Trout in the wild, which could eventually help remove them from their non-native streams.
