Demise of the dingo

Gordon C. E., Feit A., Gruber J. & Letnic M. (2015) Mesopredator suppression by an apex predator alleviates the risk of predation perceived by small prey. Proc. R. Soc. Biol. Sci. Ser. B 282, 20142870.

Aim: 
To investigate if the suppression of abundance and activity of a mesopredator (the feral cat) by an apex predator (the dingo) has positive effects on both abundance and foraging efficiency of a desert rodent.
Type of Study: 
Pre-existing contrasts ("natural experiment") and Manipulative experiment
Key Results: 
This study suggests that apex predators’ suppressive effects on mesopredators extend to alleviate both mesopredators’ consumptive and non-consumptive effects on prey.
Treatments: 
dingo no dingo control
Response: 
Alleviation of mesopredators’ non-consumptive effects could potentially extend to the demography of N. fuscus and contribute to increased abundances, if greater foraging efficiency in the presence of dingoes translates to increased survival and reproductive success.
Models: 
Frequentist
