The rediscovery of remnant Florida panthers (Puma concolor coryi) in southern Florida swamplands prompted a program to protect and stabilize the population. [] Key Result We have assessed the demographic, population-genetic, and biomedical consequences of this restoration experiment and show that panther numbers increased threefold, genetic heterozygosity doubled, survival and fitness measures improved, and inbreeding correlates declined significantly. Although these results are encouraging, continued…

A cat's tale: the impact of genetic restoration on Florida panther population dynamics and persistence.

Examination of the dynamics and persistence of the endangered Florida panther Puma concolor coryi population and the potential influence of genetic restoration on population growth and persistence parameters provides strong evidence that genetic restoration substantially contributed to the observed increases in theFlorida panther population.

The impact of genetic restoration on cranial morphology of Florida panthers (Puma concolor coryi)

A high-resolution digital imaging system was used to compare cranial morphology from several groupings of Florida panthers that were defined by genetic restoration to elucidate any morphological changes this event may have had on cranial profile, and indicated that cranial measurements ofFlorida panthers were not significantly altered by genetic restored.

Intentional genetic introgression influences survival of adults and subadults in a small, inbred felid population.

The results indicate that intentional admixture, achieved here by releasing individuals from another population, appears to have been successful in improving demographic performance in this highly endangered population of Florida panthers.

Long-term evaluation of male Florida panther (Puma concolor coryi) reproductive parameters following genetic introgression

The progressive improvement of sperm metrics demonstrates that the benefits of genetic introgression continue to have a positive impact on the population >25 years since the release of the Texas pumas, however, the Florida panther population remains small, isolated, and vulnerable to deterministic and stochastic events that warrants continued monitoring.

Genetic Restoration of Black Rhino In South Africa: Conservation Implications

Globally, wildlife populations are becoming increasingly small and isolated. Both processes contribute to an elevated risk of extinction, notably due to genetic factors related to inbreeding

Does genetic introgression improve female reproductive performance? A test on the endangered Florida panther

It is suggested that genetic introgression can have differential effects on components of fitness and highlight the importance of examining multiple demographic parameters when evaluating the effects of management actions.

Mountain lion genomes provide insights into genetic rescue of inbred populations

A high-quality mountain lion genome is assembled and a panel of resequenced individuals from across their geographic range is analyzed, finding strong geographical structure and signatures of severe inbreeding in all North American populations.



Estimation of the bottleneck size in Florida panthers

The recent intensive monitoring both before and after the introduction of Texas pumas in 1995 will make the recovery and genetic restoration of Florida panthers a classic study of an endangered species.

Importance of Genetic Variation to the Viability of Mammalian Populations

  • R. Lacy
  • Biology, Environmental Science
  • 1997
Small populations lose genetic variability because of genetic drift, and inbreeding within populations can further decrease individual variability, and genetic threats to population viability will be expressed through their effects on and interactions with demographic and ecological processes.

Genetic rescue guidelines with examples from Mexican wolves and Florida panthers

Ten guidelines are presented that can be used to evaluate when genetic rescue is a good management option, the appropriate procedures for genetic rescue planning and management, and the potential negative genetic consequences of genetic rescue.


In three recent cases, introductions into populations with low fitness appeared to restore fitness to levels similar to those before the effects of genetic drift, and the Speke's ...


Type A Florida panthers had the lowest testicular volume and sperm-motility ratings and were the only animals exhibiting unilateral cryptorchidism, demonstrating the existence of major morphological and physiological differences among populations of F. concolor , a finding potentially related to differences in genetic diversity.

Genomic ancestry of the American puma (Puma concolor).

The marked uniformity of mtDNA and a reduction in microsatellite allele size expansion indicates that North American pumas derive from a recent (late Pleistocene circa 10,000 years ago) replacement and recolonization by a small number of founders who themselves originated from a centrum of puma genetic diversity in eastern South America.

Genetics and demography in biological conservation.

The practical need in biological conservation for understanding the interaction of demographic and genetic factors in extinction may provide a focus for fundamental advances at the interface of ecology and evolution.

Bureaucratic mischief: recognizing endangered species and subspecies.

The interpretive difficulties posed by molecular results for four endangered groups are summarized and three opinions from the Solicitor's Office of the Department of the Interior have ruled with the force of precedent that hybrids between endangered species, subspecies, or populations cannot be protected.
