摘要
两栖动物因为其独特的习性和生活史,可作为评判环境质量的指示生物。为了解海南鹦哥岭国家级自然保护区两栖动物多样性现状和时空格局,共设置11条涵盖小溪、河流和农田3种生境类型的观测样线,于2018年4、6和8月分别进行调查,共记录两栖动物9种535只,隶属于1目5科7属,其中,记录到的海南特有种脆皮大头蛙被列入《中国生物多样性红色名录》濒危(EN)等级,泽陆蛙为优势物种;各调查月份两栖动物物种多样性指标之间无显著差异,但4月和6月两栖动物个体数量明显高于8月;不同生境类型物种多样性间存在显著差异,农田生境两栖动物多样性水平相对较低。通过此次调查对鹦哥岭国家级自然保护区两栖动物现状和分布格局有了一定了解,并结合自然因素和人为因素对当地两栖动物多样性保护提出相关建议。
In the context of global biodiversity decline,biodiversity is becoming one of the hottest research topics in the field of contemporary ecology.Amphibians have unique habits and life histories,so that,they can be used as indicators to judge environmental quality.To understand the current status and spatio-temporal pattern of amphibian diversity in Yinggeling National Nature Reserve,Hainan Province,11 sampling transects representing three habitats(stream,river,and cropland)were established.Field investigations were conducted in April,June,and August of 2018.A total of 535 individuals belonging to one order,five families,seven genera and nine species were recorded.Limnonectes fragilis is a vulnerable species endemic to Hainan,and Fejervarya multistriata is the dominant species.Species diversity indexes did not differ significantly among the three months,whereas significantly more amphibians were observed in April and June than in August.Species diversity indexes varied significantly among the three habitat types,with all three indexes(Shannon-Wiener index,Pielou′s evenness index,and Simpson index)being comparatively lower in farmland habitats.This investigation has shown the current situation and distribution pattern of amphibians in Yinggeling Nature Reserve,and the way of how to combine with natural and anthropogenic factors in making relevant suggestions on protection of local amphibian diversity and environments.
