Carnivorous plants attract bats with echo reflectors
An international team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Greifswald, and Universiti Brunei Drussalam has discovered that Nepenthes hemsleyana – a pitcher plant found in Borneo – uses an echo reflector to attract bats. However, it is not the bats themselves that the plants are after, but their droppings. As the pitcher plants grow in soil that is low in nutrients they need additional fertiliser and the bats’ droppings provide them with vital nutrients. In return, the plants offer the bats the perfect place to sleep inside their pitchers.
