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.

Competition


[field_op_main_image]

Competition among different animals in a natural ecosystem is ubiquitous and determines many characteristics of the ecosystem. Ecologists use different mathematical models to estimate population of animals in the wild and help determine those species that are on the verge of being endangered or extinct. A new study by undergraduates at IISc has proposed a modification to an existing mathematical equation that takes competition of species into account, thus helping ecologists make accurate predictions along with actual field data.
