RZSS WildGenes blog: Arabian sand gazelle
September 25, 2015 § Leave a comment
Over the last year we’ve been involved with a project on Arabian sand gazelle with the Office for Conservation of the Environment (OCE) in Oman.
Arabian sand gazelle (Gazella marica) are listed as Vulnerable across their range and are extinct in the wild within Oman. It’s difficult to estimate true numbers, but there are probably no more than 10,000 animals living in remote sandy desert regions of the Arabian Peninsula, such as in the famous Rub’ al Khali or Empty Quarter. Today they are still under threat from illegal hunting (for meat and to a lesser extent for trophies) and habitat loss, and many exist within fenced protected areas.
The Office for Conservation of the Environment in Oman manages a collection of over 400 individual animals at the Al Wusta Wildlife Reserve, in the central region of Oman. Over the last year, RZSS WildGenes has been collaborating with the OCE to use genetic analysis to make management decisions about this valuable collection of animals.
Blood samples were collected from the majority of the animals and tested in the labs at RZSS Edinburgh Zoo. Here we ran genetic test to verify the origin and subspecies status of the animals in the collection. Gazelle taxonomy is very complicated and different gazelle species and subspecies can be hard to distinguish, so this was an important step. Information on genetic diversity and paternity then allowed us to develop breeding recommendation that would enable the population’s genetic diversity to be preserved most effectively in coming generations, both in captivity and for an anticipated reintroduction.
RZSS WildGenes works on a number of reintroductions both within Scotland and worldwide, and the aim is always to maximise the genetic diversity of the founding population to ensure that it is able to evolve and adapt in the face of change, be this environmental change or disease outbreak.
The project also involved training of Scientists from Oman at the laboratory in RZSS Edinburgh Zoo.
Over the next year, RZSS WildGenes will be working with the OCE on a similar project for Arabian oryx.
