Warren E. Johnson led the 2010 assessment of genetic restoration in the Florida panther. The study combined population-genetic, demographic and biomedical observations after introducing Texas ancestry into the small Florida population. It reported increased heterozygosity, improved survival and fitness measures, and reduced correlates of inbreeding.[ref]
Genetic Restoration of the Florida Panther by Warren E. Johnson and others. Abstract and results: genetic, demographic and biomedical consequences
The important scientific connection is between gene flow and population performance. Counting animals alone would not establish whether genetic diversity had changed; genotypes alone would not establish whether survival improved. Studying both helps evaluate genetic rescue, while the ecological setting and continued population management remain part of the interpretation.
