Dogs have been introduced in various places across the world, where they were not found before by humans. In a recent study, researchers from the Ashoka Trust for Research in Ecology and the Environment study how dogs affect the local biodiversity.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
