Welfare science of prey base management for jaguar conservation, examining how prey depletion affects jaguar health, ranging behavior, and the welfare of individual jaguars in prey-stressed habitats.
The welfare science of jaguar prey base management demonstrates how individual predator welfare is linked to the ecological integrity of entire prey communities. A jaguar in prey-depleted habitat is a jaguar experiencing nutritional stress — with measurable body condition impacts, extended and riskier ranging, and increased exposure to lethal human conflict. This welfare chain — prey depletion to jaguar stress to livestock conflict to jaguar death — is broken at its most effective point by protecting prey populations. Anti-poaching enforcement that might appear to be purely conservation intervention is simultaneously an effective jaguar welfare intervention by restoring the nutritional security that enables jaguars to live within adequate territories without encountering humans and livestock.
