New Genetic Test Aims to Preserve Gibbon Populations

A new genetic test developed by Dr. Lauren Lansdowne, a PhD student at the University of Leicester, in collaboration with ape specialists at Twycross Zoo, aims to aid in the preservation of endangered gibbon populations. This test, which utilizes mitochondrial DNA, can reliably identify the species of individual gibbons, a crucial step in managing their conservation.

Gibbons, which are small apes closely related to great apes, face significant threats, with nearly all 20 species classified as either endangered or critically endangered. The primary dangers to their survival include habitat loss and the exotic pet trade. Captive breeding programs exist to help maintain gibbon populations, but distinguishing between species is challenging, particularly when hybrids are involved. This difficulty complicates efforts to release gibbons back into the wild.

Dr. Lansdowne's research involved collaboration with Twycross Zoo, the University of Tokyo, and 19 other zoos across Europe, allowing her to analyze genetic samples from over 200 gibbons. Her findings, published in *Conservation Genetics Resources*, confirmed the species of gibbons in European zoos and identified individuals with potential hybrid ancestry.

The ability to accurately identify gibbon species is critical for several reasons. Dr. Lansdowne noted that interbreeding among gibbon species can threaten genetic integrity. Furthermore, wildlife rescue centers often receive confiscated gibbons with little documentation regarding their species, complicating rehabilitation efforts. Without accurate identification, these gibbons cannot be safely released into the wild, leading to prolonged captivity and resource strain on rescue centers.

Dr. Lansdowne emphasized that the new test provides an accessible method for zoos and rescue centers to assess their gibbon populations. This information is vital for guiding future breeding, release, and welfare decisions. Dr. Richard Badge, Associate Professor in Bioinformatics, praised the study as an example of how student research can impact endangered species protection.

• “Dr. Lansdowne's study, one chapter of her PhD thesis, is an excellent example of how research by students in the Department of Genetics, Genomics and Cancer Sciences at the University is having real world impact for the protection of endangered species, both in the wild, and their genetically informed management in captivity. We really hope this simple test will make a difference in protecting our smallest ape relatives.” — Dr. Richard Badge, Associate Professor

The development of this mitochondrial test represents a significant advancement in the conservation of gibbons, providing essential tools for managing their populations in captivity and aiding in their potential reintroduction into the wild. As gibbon species continue to face existential threats, such innovations are crucial for their survival.
