Article: [Population and distribution of western black crested gibbon (Nomascus concolor) at Ailao Mountain, Xinping, Yunnan].[show abstract] [hide abstract]
ABSTRACT: The western black crested gibbon (Nomascus concolor) is mainly distributed in Yunnan, China. Ailao Mountain is located in central Yunnan and divided into three prefectures and six counties. This mountain forms the principle distribution range for western black crested gibbon; however, there are no published data on the gibbon population inhabiting the Xinping administrative. Take the interview results conducted in 2007 and 2009 with local people as the reference, this study conducted an extensive field survey covering all possible habitats from November 2009 to January 2010 using call surveys. Among the one hundred and twenty-four gibbon groups which were confirmed across the Ailao Mountain, the largest known population of western black crested gibbons yet, 85 groups inhabit the national nature reserve and adjacent national forest, 30 groups inhabit the provincial nature reserve and nine groups inhabit the collective forest located outside the reserve and national forest. We found that the western black crested gibbons here have a patchy distribution pattern and occur at higher densities in certain areas. Moreover, the population distribution density and elevation gradient distribution decline from north to south. The results also demonstrated the importance of Ailao Mountain in the western black crested gibbon protection.Zoological Research 12/2011; 32(6):675-83.
Article: Diversity of the Birds Captured at Night in Ailao Mountain, Xinping County, Yunnan Province[show abstract] [hide abstract]
ABSTRACT: The composition of nocturnal migratory birds was investigated by light trapping at Jinshan yakou in Ailao Mountain, Xinping County, Yunnan Province from September 5th to November 5th 2007 and from September 3rd to November 7th 2008. Totally, 7943 individuals of 129 species, which belong to 23 families, 14 orders, were caught. Passerines were the main species at 58.9% of all birds captured. Laniuscristatus , Cuculuspoliocephalus , Lusciniacalliope were predominant and every one was more than 5%. The number of birds captured was highest from 20:00 to 22:00 and from 04:00 to 06:00 every day. During 2007 and 2008£¬Both of Shannon-Wiener diversity index and Pielou evenness index were lowest, and C index was highest in early period. However, both of the Shannon-Wiener diversity index and Pielou evenness index were highest, and C index was lowest in the middle stage. C index and G-F index were higher in 2007 than in 2008. But Shannon-Wiener diversity index and Pielou evenness index were higher in 2008 than in 2007. There were differences with the number and species of the birds captured at night between various birds migration localities. Geography and climate were important factors that affect the differences.Zoological Research (ISSN: 0254-5853) Vol 30 Num 3.
