DNA matchmaking in captive facilities: a case study with tigers

Background Genetics driven interventions if adopted in conservation breeding projects may enhance the overall success by prioritizing breeding among genetically most competent individuals and delaying or completely diminishing the ill effects of inbreeding. Methods and results In the present study, we investigated genetic make-up of 15 tigers housed at five different captive facilities of West Bengal in India and report the moderate level of genetic variation. We identified five tigers based on individual genetic attributes that may be prioritized for future breeding or animal exchange programmes. The occurrence of first and second order related individuals in captivity require management attention and they should be paired considering their immediate genetic background. Conclusion Considering tiger as a case study, we highlight the use of genetic assessment and necessity to validate the studbook records in formulating adaptive management strategies for long-term conservation and management of species of interest.

Automated summary

This study investigated the genetic composition of 15 tigers housed at five different captive facilities in West Bengal, India, and found a moderate level of genetic variation. Based on individual genetic attributes, five tigers were identified for prioritized breeding or animal exchange programs. The presence of first and second order related individuals in captivity requires management attention, and they should be paired according to their immediate genetic background.
