Colman N. J., Gordon C. E., Crowther M. S. & Letnic M. (2014) Lethal control of an apex predator has unintended cascading effects on forest mammal assemblages. Proc. R. Soc. Biol. Sci. Ser. B 281, 20133094.

Aim: 
To investigate if lethal control of an apex predator, the dingo, drive unintended shifts in forest ecosystem structure of mammals and vegetation
Type of Study: 
manipulative experiment
Key Results: 
Both predation by foxes and depletion of understorey vegetation by macropods were related to small mammal decline at sites where dingoes numbers were lowered by lethal control.
Treatments: 
Baiting/lethal control
Response: 
Study suggests that apex predators’ suppressive effects on herbivores and mesopredators occur simultaneously and should be considered in tandem in order to appreciate the extent of apex predators’ indirect effects
Models: 
Frequentist
Reviewer: 
Aaron Greenville
Locations: 
South-eastern NSW
Response variable : 
dingo, fox, bandicoot, possum, gliderand small mammal abundances; macropod dung counts, veg structure
Replication: 
6 paired sites
Ecosystem: 
Forest
