摘要:

采用占域模型分析了2014和2015年广西大瑶山、猫儿山、弄岗、北流大容山和北流六麻5个区域两栖动物观测数据。大瑶山记录到两栖动物21种,猫儿山23种,弄岗15种,北流大容山26种,北流六麻13种。泽陆蛙、饰纹姬蛙、花姬蛙、沼蛙和斑腿泛树蛙在5个区域都有分布。采用占域模型分析了11种常见两栖动物在空间上的占据概率,估算其占域率和探测率,将5个栖息协变量和1个探测协变量引入模型,初步分析了环境因素对两栖动物占域率分布的影响,并对占域模型的适用性、探测率及调查力度进行评估,从而优化模型以使其更广泛地应用于全国两栖动物的观测,为进一步制定科学的保护和管理对策提供信息。

Abstract:

Based on the 2014 and 2015 amphibian monitoring data of the five regions (Dayao Mountain, Mao'er Mountain, Nonggang, Darong Mountain and Liuma) of Guangxi, site occupancy analysis was done using a site occupancy model. The data show that 21 species were recorded in the Dayao Mountain, 23 in the Mao'er Mountain, 15 in Nonggang, 26 in the Darong Mountain, and 13 in Liuma. Fejervarya multistriata, Microhyla fissipes, Microhyla pulchra, Boulengerana guentheri and Polypedates megacephalus were commonly found in all the five areas. Site occupancy models were used to analyze site occupancy probabilities of the 11 commonly seen species of amphibians for estimation of their site occupancy rates and detection rates, separately. With five habitat covariates and one detection covariate introduced in, the models were used to analyze effects of environmental factors on distribution of the site occupancy rates of the amphibians, and in turn, practicability, detectivity and investigation intensity of the models were evaluated, in an attempt to modify the models and make them more extensively applicable to investigation of amphibians all over the country, and to provide information for further policy-making for scientific protection and management.
