...; Oksanen et al. 1981). This could partly explain why tri-trophic cascades have not been demonstrated experimentally in Australian systems (Allen et al. 2013a; Allen et al. 2013b). Mesopredator release can be observed in wild canid populations when suppression by humans is removed, and greater predation...

Much discussion pivots on the possibility of trophic cascade models and mesopredator release/ suppression hypotheses functioning in Australian ecosystems (Johnson and Ritchie 2013; Newsome et al. 2017; Ritchie et al. 2012; Ritchie and Johnson 2009) and the evidence for (e.g. Brook et al. 2012; Johnson...

... In many aquatic systems, cascading trophic interactions are important determinants of community structure, via top-down (predation) and bottom-up (productivity) factors. In contrast, little is known of the importance of these factors in the structuring of diverse terrestrial communities...
