Thomas H.Q. Powell and his team conducted a study that primarily focused on the impact of changing temperatures on two diverging populations of the Hawthorn fly. While one population continued to feed on the hawthorn fruit, the other resorted to consuming apple trees in the 1850s. An investigation was conducted to determine how future temperature changes may affect these populations and how they interact with parasitic wasps. The hawthorn-eating flies were resilient to shifts in temperature. This may have taken place because of greater genetic variation. The apple-eating flies were thrown out of sync with the trees, and the future … Continue reading The Tragic Fate of Hawthorn Flies in a Changing Climate: Unraveling the Web of Species Interactions
