This study provides the first robust population estimate for Wilkerr using spatially explicit capture-recapture modelling. The research estimates approximately 77 adult Wilkerr, with a 95% credible interval of 64–94 adults, across an estimated 5,515 km² study area. The results highlight the exceptionally low density and small size of this isolated population and provide an important baseline for long-term monitoring and conservation.

This study examined the interactions between target and non-target species with buried 1080 baits in southeastern Australia's Big Desert-Wyperfeld region. The findings revealed that non-target native mice accounted for 88% of bait interactions, often engaging with the baits sooner than target species like foxes and dingoes. ​​​

This study is the first to recognise Big Desert dingoes as genetically distinct, shedding light on their unique genetic structure within the broader dingo population. It highlights how geographic and ecological factors shape their diversity and emphasises the importance of preserving these local populations, which play a vital role in maintaining ecological balance and contribute to the broader genetic landscape of the species.

This study by Cairns et al. provides strong evidence that dingoes are a distinct evolutionary lineage, separate from domestic dogs. Using genetics, behaviour, ecology and archaeology, the research confirms dingoes meet all criteria to be considered taxonomically unique. Recognising dingoes as Canis dingo or Canis lupus dingo is crucial for their conservation and acknowledges their cultural significance to First Nations peoples.

This study examined dingo ancestry and domestic dog introgression across Australia, finding limited evidence of recent hybridisation in the populations examined. The results challenge long-standing assumptions that contemporary dingoes are extensively hybridised with domestic dogs and support the conservation value of genetically distinct regional dingo populations, including Wilkerr.

This study analysed the diets of dingoes, foxes and feral cats in the Big Desert, Wyperfeld and Ngarkat area. Dingoes mainly ate large native herbivores like kangaroos and emus (71% of their diet), while foxes consumed significantly more livestock and both foxes and cats preyed heavily on small native mammals, including threatened species. The findings highlight dingoes’ distinct ecological role and question the justification for broad-scale lethal control.

This study shows that male dingo urine contains chemical cues that signal age. Researchers found clear scent differences between younger, prime-aged, and older males. Wild dingoes responded most to the scent of prime-aged males, suggesting they use these cues to assess the age or status of others. This highlights how scent marking supports social and territorial behaviour in wild dingoes.
