Research overview: genetic rescue for inbred urban felid populations

When urban felid populations become severely inbred, genetic rescue, the introduction of individuals or gene flow from other populations, can restore diversity and demographic vigour. This overview synthesises the concept and its precedents, including the celebrated recovery of Florida panthers after introductions, and its relevance to freeway-isolated southern California pumas and other fragmented felids. It examines the genetic and ecological rationale, the risks of outbreeding and disease, and the choice between assisted gene flow and restoring natural connectivity through crossings. The synthesis frames genetic rescue as a powerful but carefully weighed tool for felid populations stranded by urbanisation.
