摘要:

区域物种多样性评价是全球生物多样性研究的重要部分。研究两栖动物物种丰富度的海拔分布格局能为物种多样性的保护提供科学依据。为了解江西武夷山国家级自然保护区(简称保护区)两栖动物多样性及海拔分布特点,于2014年7月22日—8月4日,选取22条样线开展调查,同时将保护区海拔300~2161 m区间按200 m的间隔分为10个海拔段,对两栖动物的海拔分布特点进行研究。结果表明:1)保护区现已记录两栖动物29种,隶属2目9科22属,以蛙科为主,占两栖物种总数的37.9%;2)崇安湍蛙(Amolops chunganensis)为保护区新纪录;3)两栖动物物种多样性大致呈先平台后递减的海拔分布特点,这可能主要受生境复杂性的影响。此外,本研究采用Stevens法和逐种法对Rapoport法则进行了验证,结果表明,保护区的两栖动物很难判断是否支持Rapoport法则。
 

Abstract: 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.
