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")
Show that a trophic cascade resulting from an apex predator’s lethal effects on herbivores extends to the soil nutrient pool.dynamics.
apex predators could effect ecosystem productivity
Strzelecki Desert, Australia
Response variable :
fauna counts, vegetation plots, proportaion of prey in scats
Fauna 2, scats 2 x 5km transects, herbivore exclusion 4, Soil 9 cores
