摘要

摘要在热带国家,频繁的人为干扰是包括鳞翅目在内的许多昆虫类群的群落多样性减少和局部灭绝的主要驱动因素。我们评估了人为干扰对埃塞俄比亚克勒山脉五种不同土地利用类型(破碎森林、农田、牧场、农村居民点和未受干扰的天然林)鳞翅目群落的影响。采用20 W紫外LED灯连续12个月在19个地点取样鳞翅目。共采集了14科339种4559份标本。自然森林的多样性最高,其次是破碎森林、农村居民点、牧场和农田。5种土地利用类型间多样性估算的月变化趋势存在较大差异,Hill - shannon和Hill - Simpson值最高的月份不在天然林,而在乡村聚落和破碎林。稻田和牧场的优势种数最高,约为10%。多元结果清楚地强调了天然林地点与所有其他地点的分离,总的来说,每种土地利用的一致性很大。维管植物的数量与鳞翅目的种类呈高度正线性关系。该研究结果将有助于指导保护管理的优先事项,以防止不可逆转的生物多样性丧失,并维持对农村社区可持续发展至关重要的生态系统提供服务。关键词:蛾类;非洲土地利用;生态系统

Lepidoptera as a tool for the assessment of human disturbance impacting ecological and taxonomic diversity in the Choke Mountains, Ethiopia
AbstractIn tropical countries, frequent anthropogenic disturbances are primary drivers of the reduction in community diversity and local extinction of many insect taxa, including Lepidoptera. We assessed the impact of anthropogenic disturbances on lepidopteran assemblages across five different land use types (Fragmented Forest, Crop Fields, Pasture Land, Rural Settlements and undisturbed Natural Forest) in the Choke Mountains, Ethiopia. Lepidoptera were sampled using 20 W UV LED lights in 19 sites for 12 consecutive months. A total of 4 559 specimens representing 14 families and 339 species were sampled. The highest diversity was obtained from the Natural Forest, followed by the Fragmented Forest, Rural Settlements, Pasture Land and Crop Fields. The monthly trends of the diversity estimates showed strong differences among the five land use types, with months when the highest Hill–Shannon and Hill– Simpson values were observed not in the Natural Forest, but in the Rural Settlements and Fragmented Forest. The highest dominance values were observed in the Crop Fields and Pasture Land, with dominant species percentages of about 10%. The multivariate results clearly highlight the separation of the Natural Forest sites from all other sites and, in general, great consistency within each land use. A high positive linear relationship between the number of vascular plants and sampled Lepidoptera species was observed. The results of this study will be useful for guiding conservation management priorities to prevent irreversible biodiversity loss and maintain ecosystem provisioning services that are essential for the sustainable development of rural communities.Keywords: mothsAfricaland useecosystem monitoringdiversity measures

期刊介绍: African Zoology , a peer-reviewed research journal, publishes original scientific contributions and critical reviews that focus principally on African fauna in terrestrial, freshwater, and marine ecosystems. Research from other regions that advances practical and theoretical aspects of zoology will be considered. Rigorous question-driven research in all aspects of zoology will take precedence over descriptive research. The Journal publishes full-length papers, critical reviews, short communications, letters to the editors as well as book reviews. Contributions based on purely observational, descriptive or anecdotal data will not be considered. The Journal is produced by NISC in association with the Zoological Society of South Africa (ZSSA). Acceptance of papers is the responsibility of the Editors-in-Chief in consultation with the Editors and members of the Editorial Advisory Board. All views expressed are those of the author and not necessarily those of the Editors or the Department.
