Genetic assessment of captive red panda (Ailurus fulgens) population

چکیده
Red panda (Ailurus fulgens) is threatened across its range by detrimental human activities and rapid habitat changes necessitating captive breeding programs in various zoos globally to save this flagship species from extinction. One of the ultimate aims of ex situ conservation is reintroduction of endangered animals into their natural habitats while maintaining 90 % of the founder genetic diversity. Advances in molecular genetics and microsatellite genotyping techniques make it possible to accurately estimate genetic diversity of captive animals of unknown ancestry. Here we assess genetic diversity of the red panda population in Padmaja Naidu Himalayan Zoological Park, Darjeeling, which plays a pivotal role in ex situ conservation of red panda in India. We generated microsatellite genotypes of fifteen red pandas with a set of fourteen loci. This population is genetically diverse with 68 % observed heterozygosity (HO) and mean inbreeding (FIS) coefficient of 0.05. However population viability analysis reveals that this population has a very low survival probability (<2 %) and will rapidly loose its genetic diversity to 37 % mainly due to small population size and skewed male-biased sex ratio. Regular supplementation with a pair of adult individuals every five years will increase survival probability and genetic diversity to 99 and 61 % respectively and will also support future harvesting of individuals for reintroduction into the wild and exchange with other zoos.

Characterization of the Gut Microbiota in the Red Panda (Ailurus fulgens)
The red panda is the only living species of the genus Ailurus. Like giant pandas, red pandas are also highly specialized to feed mainly on highly fibrous bamboo. Although several studies have focused on the gut microbiota in the giant panda, little is known about the gut microbiota of the red panda. In this study, we characterized the fecal microbiota from both wild (n = 16) and captive (n = 6)...

In a recent survey, 30% of the European red panda (Ailurus fulgens) population was found to be infected with a newly discovered metastrongyloid nematode. In a following prospective study, four naturally infected captive-bred red pandas infected with this parasite were examined and compared with two uninfected control animals. On clinical examination, no abnormalities were detected with respect ...

The red panda (Ailurus fulgen) is reddish brown, long-tailed mammal, found in the mountain forests of the Himalayas and adjacent areas of eastern Asia, which subsists mainly on bamboo (Choudhury, 2001). This species as with most Carnivora, possesses paired anal glands used by both sexes to scent-mark. Red pandas emit a musky odor from these glands when excited (Nowak, 1991), and according to Ro...

The red panda (Ailurus fulgens) has a similar diet, primarily bamboo, and shares the same habitat as the giant panda, Ailuropoda melanoleuca. There are considerable efforts underway to understand the ecology of the red panda and to increase its populations in natural reserves. Yet it is difficult to design an effective strategy for red panda reintroduction if we do not understand its basic biol...
