Demise of the dingo

Morris T. & Letnic M. (2017) Removal of an apex predator initiates a trophic cascade that extends from herbivores to vegetation and the soil nutrient pool. Proc Biol Sci 284, 20170111.

Aim: 
To investigate the effects that removal of an apex predator has on herbivore abundance, vegetation and the soil nutrient pool
Type of Study: 
Pre-existing contrasts ("natural experiment")
Key Results: 
Show that a trophic cascade resulting from an apex predator’s lethal effects on herbivores extends to the soil nutrient pool.dynamics.
Treatments: 
Dingo/non-dingo, grazed/non-grazed
Response: 
apex predators could effect ecosystem productivity
Models: 
Frequentist
