... their effects can be beneficial. The positive effects of pests arise when they become deeply embedded in ecological communities and are involved in webs of direct and indirect interactions with other species. In this paper, I first outline the concepts of direct and indirect interactions, and then describe two...

Grazing by livestock is the main “direct” impact of pastoral activity and has resulted in widespread changes in habitat structure and a decrease in primary productivity. The loss in primary productivity may have reduced...

Thus, the overall impact of Cane Toads on Carpet Pythons (and likely, other predator species) is a balance between direct costs and indirect benefits. Negative impacts on individuals may not necessarily...

More recently, research has focussed on the indirect effects that removal of dingoes has on ecosystems (Letnic et al...
