The effect of removing keystone species has been extensively studied, particularly with respect to wolves. Just google "keystone species" and the first result features a case study on grey wolf removal and restoration in Yellowstone: https://www.nature.com/scitable/knowledge/library/keystone-species-15786127/ https://www.nature.com/scitable/knowledge/library/keystone-s...
