Predator control promotes invasive dominated ecological states
Ecology Letters (2010) 13: 1008–1018 Abstract Invasive species are regarded as one of the top five drivers of the global extinction crisis. In response, extreme measures have been applied in an attempt to control or eradicate invasives, with little success overall. We tested the idea that state shif...
