Research overview: the subspecies inflation problem in carnivores and cats

Subspecies inflation, the naming of many weakly supported geographic forms, has long plagued large carnivore taxonomy and complicates conservation. This overview explains how cats accumulated dozens of dubious subspecies through historical type-based descriptions, and why inflated lists are problematic: they can fragment conservation effort, misdirect captive breeding, and exaggerate or understate true diversity. It contrasts inflation with the opposite risk of lumping away genuinely distinct evolutionary units. Using examples from tigers and leopards, the piece shows how molecular phylogeography and the task force trimmed inflated lists while flagging populations that remain genuinely diagnosable. It argues that the goal is accuracy, not minimalism, and that both over-splitting and over-lumping carry costs for the animals being classified.
