This study finds no consistent decline in vertebrate abundance or stability with distance from range or climate niche centres, challenging assumptions in ecological models.

The paper quantifies vertebrate population declines under various threats and finds that multiple interacting threats, not just habitat loss or exploitation, drive faster declines.

This study shows response diversity drives community stability in food webs, with food web structure playing a secondary role.

This study shows reintroductions can destabilize food webs and trigger extinction cascades, often undetected because success is measured only by reintroduced species survival.
