摘要:
两栖动物因其生态功能和营养结构中的位置,成为生态系统中重要的类群,对维持群落结构和生态稳定具有重要意义. 监测和分析两栖动物多样性,可以准确地掌握种群动态和主要致危因素,进而对其进行及时有效的保护. 本研究于2018年4月、6月和8月,在福建宁德样区设置了10条样线,针对两栖动物进行了3次样线调查; 依据农田、公路、池塘、河流4种样线类型,用Shannon-Wiener、Simpson和 Pielou指数量化不同月份的物种多样性并进行差异性分析,同时分析了人口聚集区对物种多样性的影响. 调查期间共监测到两栖动物513只,隶属1目5科9属10种; 其中虎纹蛙(Hoplobatrachus rugulosus)为“国家二级”和易危(VU)保护动物、其余9种为国家“三有”保护动物; 泽陆蛙(Fejervarya multistriata)、黑眶蟾蜍(Duttaphrynus melanostictus)、沼水蛙(Hylarana guentheri)均具有较高的优势度指数(Pi),为该样区的优势物种. 不同月份间物种多样性存在显著差异,6月份的多样性指数均最高. 物种的交替出现与生活史周期相吻合,说明该地较适宜两栖动物生存,种间竞争压力不大. 人口聚集区对两栖动物的分布具有一定的影响,与人口聚集区的地理距离越远,物种多样性越高. 另外,结合当地两栖动物分布格局与经济发展,对其多样性保护提供了对策与建议.
Abstract:
Amphibians,because of their ecological function and position in the nutritional structure,have become one of the most important taxa in the ecosystem,playing a critical role in maintaining community structure and ecological stability. Monitoring and analyzing amphibian diversity are of importance in obtaining accurate information about their population dynamics and the main factors affecting such dynamics. In this study,ten sampling lines of four types(farmland,road,pond and stream)set up in the densely-populated area of Ningde,Fujian,East China,were surveyed thrice in April,June and August 2018 for amphibians. We quantified species diversity and its seasonal variation by calculating Shannon-Wiener,Simpson and Pielou indices based on data collected in the three months. We also assessed the anthropogenic impact on species biodiversity in this densely-populated area. A total of 513 amphibians were observed in the survey,and these individuals belonged to one order,five families,nine genera and ten species. All the ten species are protected due to their scientific,economic and/or social values,with Hoplobatrachus rugulosus being the only second-class protected and vulnerable(VU)animal. Fejervarya multistriata,Duttaphrynus melanostictus,and Hylarana guentheri were the three dominant species in this area. Seasonal changes in species diversity were evident,with the greatest diversity index recorded in June. Our data allow the following conclusions. Firstly,the alternating occurrence of species coincides with the life cycle. Secondly,the area we sampled is suitable for amphibians to survive. Thirdly,interspecific competition is not strong,and anthropogenic impact is a factor affecting the distribution of amphibians as revealed by the positive correlation between geographical distance from human habitation and species diversity in this area. Considering the local economic development and distribution pattern of amphibians,we proposed several strategies for protection of amphibian diversity in this densely-populated area.
