We tested the idea that state shifts to invasive dominance are symptomatic of losses in ecosystem resilience, due to the suppression of apex predators.
Type of Study:
Lethal control fractures dingo social structure and leads to bottom-up driven increases in invasive mesopredators and herbivores.
Dingo control vs un-controlled properties
Where control is relaxed, dingoes re-establish top–down regulation of ecosystems, allowing for the recovery of biodiversity and productivity.
Model selection, principle components
Response variable :
index of abundance, scentmarking rates
5 dingo control and 2 uncontrolled sites.
