Fungal infestation boosts fruit aroma and fruit removal by mammals and birds

Abstract For four decades, an influential hypothesis has posited that competition for food resources between microbes and vertebrates selects for microbes to alter these resources in ways that make them unpalatable to vertebrates. We chose an understudied cross kingdom interaction to experimentally...
