Published: 13 April 2021
...Renee L. Brawata ABSTRACT The removal of apex carnivores from ecosystems can impact the abundance and diversity of species in lower trophic levels. In arid ecosystems, where “bottom up” forces of primary productivity and resource availability strongly affect trophic interactions, the role of “top...

... 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...

Approximately 75% of the invertebrates caught were soil detritivores during their larval stage. Because invertebrates are so diverse, and our knowledge of their ecological functioning...

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...
