Demise of the dingo

Choquenot D. & Forsyth D. M. (2013) Exploitation ecosystems and trophic cascades in non-equilibrium systems: pasture – red kangaroo – dingo interactions in arid Australia. Oikos 122, 1292-306.

Aim: 
Test predictions of the exploitation ecosystem hypothesis (EEH) and model the interactions between pasture, red kanagroos and dingoes.
Type of Study: 
Modelling. Simulation.
Key Results: 
Pasture growth drives kanagroo numbers, but when present, dingoes reduced the upper abundances of kanagroos. This effect was stronger in more productive environments.
Response: 
Culling of dingoes has an effect on EEH and trophic cascades.
Models: 
Mathematical model used
Reviewer: 
Aaron Greenville
Locations: 
Arid Australia
Response variable : 
Pasture biomass, kangaroo and dingo densities.
Replication: 
model run for 10 000 weeks and 500 simulations for all stochstic scenarios.
Ecosystem: 
Arid zone
