Despite low genetic diversity, the critically endangered Cat Ba langurs (Trachypithecus poliocephalus) have retained key genetic traits that help them survive in their isolated environment on Cat Ba Island in Vietnam, says a new study.
- One of the remarkable adaptations is the ability to drink salt water.
- Due to the dramatic decline of its population, Cat Ba langurs suffer from genetic impoverishment, high inbreeding and a potentially increased susceptibility to disease.
- Analysis of their genetic information shows that genetic diversity has been maintained in functionally important areas of their genetic information.
- This enables the Cat Ba langurs to continue to cope adequately with changing environmental conditions.
- This extraordinary ability is a direct consequence of their isolated island home, where there are only limited freshwater sources.
