Evaluation of regional species diversity is one of the important components of the global biodiversity research. Studies on vertical distribution pattern of amphibian species richness could provide a scientific basis for biodiversity conservation. In order to understand the amphibian biodiversity and the altitudinal distribution characteristics in Wuyishan Nature Reserve, we surveyed the amphibians in 22 sample lines from 300 to 2161 m, which were divided into 10 sections for every 200 m from July 22 to August 4, 2014. The results showed that: (1) Thirty two species of amphibians belonging to 22 genera, 9 families, 2 orders were recorded, of which the Ranidae (37.9% of total species) was the predominant family. (2) Amolops chunganensis was a new record in the nature reserve. (3) With the increase of altitude, the amphibian richness presented a plateau pattern then decreased, which was mainly influenced by habitat complex. Meanwhile, the Stevens and cross species methods were used to examine whether Rapoport’s rule is applicable to species specific elevational range sizes of amphibians. The results suggested that amphibian range in this nature reserve did not support Rapoport’s rule. © 2015, editorial Board of Chinese Journal of Ecology. All rights reserved.

The research area belongs to Jiangxi Wuyishan National Nature Reserve, it is the highest mountain land in east of China subtropical area, and the original nature of forest is relatively intactly preserved. During 2004—2012, one main line and six auxiliary sample lines were laid across all the typical habitats at the scope of the altitude between 300 and 2160m in the research area, 188 kinds of forest breeding birds have been recorded, occupies 71.76 percent of the species number of forest breeding birds in China's eastern hilly and plain subregion. Among these breeding birds, dominant families with 10 kinds or more species number are: Turdidae 13 kinds, Muscicapidae 10 kinds, Timaliidae 21 kinds, Sylviidae 22 kinds, occupies 35.1 percent of the species number of forest breeding birds in the research area and 51.2 percent of the Passeriformes. The research area was divided into 4 categories of habitat in accordance with altitude, vegetation form and human interference degree and analyzed. The result shows that recovering secondary area have the most species number(138 kinds) > original forest (127 kinds) > production activities interference area (119 kinds) > peak scrub meadow area (51 kinds), among the four areas the numerical value of every index of peak scrub meadow area is the smallest for the habitat condition factors, the remaining three kinds of habitat subareas sustain Mid-domain effect both in overall bird species number, Passeriformes bird species number, and in the bird species number of dominant families. The G-F index reduces as the altitude increases, namely production activities interference area(DG-F =0.775) > recovering secondary area (DG-F =0.772) > original forest (DG-F =0.760) > peak scrub meadow area (DG-F =0.603);in the G-F index analysis of Passeriformes bird species, the G-F index of original forest (DG-F =0.650) is slightly higher than that of the recovering secondary area (DG-F=0.633), which shows that bigger forest inner space and the various interior hierarchical structure of climax community have positive significance for the diversity of Passeriformes birds. Analysis shows that recovering secondary area and original forest area have the highest similarity coefficient, and indicates that the ecological functions of secondary forest after about 30 years natural succession recovery is already approximate to that of the climax community for forest breeding birds,while the similarity coefficient of production activities interference area and peak scrub meadow area is the lowest. Meanwhile, the Birds ecological Niche differentiation manifestation of Galliformes is most typical. © 2014, Ecological Society of China. All rights reserved.
