@cambridgeuniversity: 🐸 "I thought, this is obviously a prank." When Dr Silviu Petrovan from St Catharine's College was asked to identify a live frog found in roses in a UK florists, he was stunned: it was a South American tree-frog. "It made me realise that if you can get such fragile small vertebrates arriving alive in a flower shipment without being noticed at customs, just how hard it must be to detect very small agricultural insect pests or their eggs," he said. So he launched a study. What he found was alarming: insects, fungi, reptiles, spiders and agricultural pests are being transported live across the world on ornamental plants destined to brighten up our homes and gardens. #CambridgeUniversity #UniversityOfCambridge #Biology #Frogs #Conservation
