Aim: 
Proposed the Enemy Constraint Hypothesis, which predicts weakened top-down effects on mesopredators towards the edge of top predators’ ranges.
Type of Study: 
Pre-existing contrasts ("natural experiment")
Key Results: 
The effects of top predators on mesopredators increase from the margin towards the core of their ranges
Treatments: 
mesopredatorss
Response: 
Studies assessing the strength of topdown mesopredator control will need to consider whether the mesopredator is located on the periphery or core of the top predator’s range
Models: 
Frequentist
Reviewer: 
Aaron Greenville
Locations: 
Australia, Europe and North America
Response variable : 
Bounty records
Replication: 
North America:136 hunting units; Europe 255 hunting units; Australia 145 100 x 100km areas.
Ecosystem: 
From Arid to forest,
