What to know about Scientific Methodology

Researchers used DNA metabarcoding to analyze the stomach contents of culled feral cats in Australia, finding that traditional manual analysis underestimates the variety of native mammal and bird species consumed. The study suggests that integrating DNA analysis with traditional methods will provide a more accurate understanding of the impact of invasive predators on native wildlife.

What happened

Feral cats likely kill far more Australian native animals than we thought: First DNA analysis Lisa Lock Scientific Editor Alexander Pol Deputy Editor Australia's unique animal species are in sharp decline, with more than 40 mammal extinctions over the past…

Why it matters

This atrocious mammal conservation record is the worst in the world.

Common ground

Unfortunately, this is not simply a historical problem—almost 700 animals are currently at risk of future extinction.

The specific figure of 'almost 700 animals' is mentioned in the cross-reference (The Conversation) and one web search result that appears to be mirroring the same reporting. Other sources discuss general declines or different numbers (e.g., 67 official extinctions), making this specific number difficult to corroborate across truly independent organizations.
