This occurs because apex predators can exert strong suppressive effects on their prey and competitors and perturbation of these interactions can shift the balance of interactions between dyads of species at lower trophic levels and trigger trophic cascades. Dingoes (<jats:italic>Canis dingo<\/jats:italic>) are Australia\u2019s largest mammalian carnivore. Because they are a pest to livestock producers, dingo populations are suppressed in many regions. Suppression of dingo populations has been linked to a suite of ecosystem changes due to ensuing population irruptions of their prey and competitors. Here, we investigate the impact that the suppression of dingoes has on the diet of wedge-tailed eagles (<jats:italic>Aquila audax<\/jats:italic>) in Australia\u2019s Strzelecki Desert. Wedge-tailed eagles are generalist predators that readily shift their diet in relation to prey availability. We assessed the abundance of species frequently preyed on by eagles and quantified prey remains at eagle nests located on either side of a dingo-proof fence where dingoes were common and rare, respectively. Wedge-tailed eagles consumed more species where dingoes were rare compared to where dingoes were common. Kangaroos (Macropodidae) and western bearded dragons (<jats:italic>Pogona vitticeps<\/jats:italic>) were more abundant and were consumed more frequently by eagles where dingoes were rare. Introduced European rabbits (<jats:italic>Oryctolagus cuniculus<\/jats:italic>) were the prey item most frequently identified at eagle nests. However, rabbits were more abundant and their remains were found at a higher proportion of nests where dingoes were common. Our results provide evidence that shifts in the composition of vertebrate assemblages associated with the presence\/absence of dingoes, particularly the irruption of kangaroos, influence the diet of wedge-tailed eagles. More generally, by showing that the presence\/absence of dingoes can influence the diet of wedge-tailed eagles, our study highlights how pervasive apex predators\u2019 effects on ecosystems can be.<\/jats:p>","DOI":"10.1007\/s00114-022-01804-x","type":"journal-article","created":{"date-parts":[[2022,6,8]],"date-time":"2022-06-08T09:05:50Z","timestamp":1654679150000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Irrupting prey populations in the absence of a mammalian apex predator drive shifts in prey selection by eagles"],"prefix":"10.1007","volume":"109","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9255-9167","authenticated-orcid":false,"given":"Matthew","family":"Brun","sequence":"first","affiliation":[]},{"given":"Amoi Stubbs","family":"Oliver","sequence":"additional","affiliation":[]},{"given":"Joel","family":"Alves","sequence":"additional","affiliation":[]},{"given":"Alex","family":"Nankivell","sequence":"additional","affiliation":[]},{"given":"Mike","family":"Letnic","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2022,6,8]]},"reference":[{"key":"1804_CR1","doi-asserted-by":"publisher","first-page":"1525","DOI":"10.1002\/esp.1362","volume":"31","author":"RL Beschta","year":"2006","unstructured":"Beschta RL, Ripple W (2006) River channel dynamics following extirpation of wolves in northwestern Yellowstone National Park, USA.
