Predator presence alone can change prey feeding behavior without a single kill occurring.
For thousands of years, forest ecosystems in central and southern China evolved alongside the South China tiger. Prey species adapted behaviors to avoid ambush, including heightened vigilance and altered grazing patterns. Vegetation communities developed within a predator-regulated herbivore dynamic. When that apex predator disappears, evolutionary relationships become disrupted. Prey may expand into areas previously avoided, reshaping plant distribution. These shifts can accumulate gradually yet permanently. Ecosystems that coevolved with predators do not instantly recalibrate when they vanish.

Behavioral ecology demonstrates that fear itself can structure ecosystems. The mere presence of a predator alters prey feeding intensity and habitat use. Removing that influence changes how energy flows through the system. Forest patches once lightly grazed may experience heavier browsing. The cumulative impact over decades can alter species composition at scale.
The South China tiger’s absence creates what some ecologists describe as orphaned ecosystems, systems missing a historical regulator. Restoration efforts must consider not just physical habitat but lost ecological roles. Reintroducing a predator after long absence may produce unexpected adjustments. The complexity underscores how deeply apex carnivores embed within environmental networks. Their disappearance echoes far beyond direct predation.
