Demise of the dingo

Wallach A. D., Johnson C. N., Ritchie E. G. & O’Neill A. J. (2010) Predator control promotes invasive dominated ecological states. Ecology Letters 13, 1008-18.

Aim: 
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: 
Manipulative experiment
Key Results: 
Lethal control fractures dingo social structure and leads to bottom-up driven increases in invasive mesopredators and herbivores.
Treatments: 
Dingo control vs un-controlled properties
Response: 
Where control is relaxed, dingoes re-establish top–down regulation of ecosystems, allowing for the recovery of biodiversity and productivity.
Models: 
Model selection, principle components
Reviewer: 
Aaron Greenville
Locations: 
Arid Australia
Response variable : 
index of abundance, scentmarking rates
Replication: 
5 dingo control and 2 uncontrolled sites.
Ecosystem: 
Arid zone
