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