Dingoes are regarded as apex predators and possibly perform an ecological key function. Likely (with increasing evidence from scientific research), they control the diversity of the ecosystem by limiting the number of prey and keeping the competition in check.
Cats in Australia have no natural predators except dingoes and wedge-tailed eagles, and as a result, they are apex predators where neither the dingo nor the eagle exists. [19] Also, dingos do not appear to affect the activity of cats. [20]

The thylacine was an apex predator, [4] ... Examinations of dingo and thylacine skulls show that although the dingo had a weaker bite, its skull could resist greater ...
An apex predator, also known as a top predator or superpredator, is a predator [a] at the top of a food chain, without natural predators of its own. [ 6 ] [ 7 ] Apex predators are usually defined in terms of trophic dynamics , meaning that they occupy the highest trophic levels .
“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
It has been partly successful, though dingoes can still be found in parts of the southern states. Although the fence has helped reduce losses of sheep to predators, this has been countered by holes in fences found in the 1990s through which dingo offspring have passed [2] and by increased pasture competition from rabbits and kangaroos.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
